    [0001] TECHNICAL FIELD The present invention relates to the field of electronic wind musical instruments that allow the production of musical notes by positioning the fingers of the hands on keys and blowing into a mouthpiece. The main objective of the invention is to improve the behavior of the electronic wind musical instrument and to strive for an acoustic wind musical instrument, in order to find the same feeling of play, which allows the musician to continue to work on his playing technique and, thus, to progress on both types of instruments.
    [0002] One of the advantages of electronic wind musical instruments is to allow musicians to practice a wind musical instrument at any time, without causing any discomfort to those around them. Indeed, acoustic wind musical instruments are by nature noisy, which does not allow the musician to practice at home, at any time, without disturbing other members of the family or even its neighborhood. Unless you have a soundproof cabin, very expensive and uncomfortable. Thanks to the electronic wind musical instruments, musicians can practice quietly in their homes in all circumstances using a headset, without any hindrance to their neighborhoods. Another advantage of an electronic wind musical instrument is to allow the musician to play amplify, very simply, so as to integrate in a controlled manner with other instruments. Another advantage of this type of instrument lies in the fact of being able to dissociate the technique of fingering from the technique of breath, for learning. Thus, the musician can concentrate on the notes without needing to master a mouthpiece or mouthpiece.
    [0003] Other advantages also exist, for example the possibility of modifying the range of playable notes, of tuning the instrument to measure and reproducibly, and of playing different types of sounds from a single instrument. State of the art 3036838 2 In a first embodiment, according to the prior art, the electronic wind musical instruments comprise a mouth in which the musician blows. A pressure sensor is connected to this mouthpiece, the pressure sensor comprising a membrane which deforms when the musician blows into the mouth. An electronic processing system is connected to the sensor and makes it possible to measure the deformations of the membrane. Keys are also arranged on the instrument and connected to the electronic processing system, said electronic processing system also for measuring the contacts on these keys. The concomitant action of breath in the mouth and manipulation of the keys by the musician allows the electronic processing system to produce musical notes. This design does not reproduce at all the playing sensation of an acoustic wind musical instrument, since the musician blows into the mouth of a pipe whose end communicates directly with the pressure sensor, this mouth being through consequently clogged. To overcome this drawback, an alternative embodiment provides the addition of means 15 for evacuating the blown air which are configured on the mouth or directly on the pressure sensor. This allows an escape of the air when the musician blows in the mouth and, thus, to have sensations a little closer to those of a wind acoustic instrument. By way of example, such an electronic wind instrument design appears in US Pat. No. 5,170,003 where the mouthpiece includes an air vent hole. It is the same in US Patent 3,767,833 which provides a vent hole with, in addition, an adjustable screw for adjusting the evacuation of air. When the air evacuation means are provided directly on the pressure sensor, it comprises a discharge orifice, a pipe being connected to this discharge orifice and configured to open out of the pressure sensor. instrument, either near the sensor or at the longitudinal end of the instrument. The results of this variant of implementation remain however insufficient since the flow of air that evacuates remains very limited. This type of instrument therefore always requires an adaptation of the way of playing for the musician who, therefore, can not go from an electronic wind instrument to an acoustic wind instrument, and vice versa, keeping the same playing conditions.
    [0004] It is also known from US Pat. No. 5,140,888 which describes an electronic wind musical instrument intended to reproduce the sensations of an acoustic wind musical instrument. The musical instrument includes a pipe that extends the full length of the instrument, said pipe having an inlet to a mouth (or spout) and an outlet for discharging the air blown. A pressure sensor is connected upstream on the pipe, close to the mouth, and a chamber provided with a valve is arranged between two portions of the pipe, said chamber allowing to adjust the flow of air as a function of the pressure, when the musician blows into the instrument. SUMMARY OF THE INVENTION The invention uses a variant of an electronic wind musical instrument to reproduce the sensations of an acoustic wind musical instrument, that is, to blow naturally into the mouthpiece. while manipulating the keys to produce the notes, as a musician does with an acoustic wind musical instrument. For this purpose, the invention relates to an electronic wind musical instrument which comprises a body provided with keys configured to be manipulated with the fingers.
    [0005] Different variants of keys are possible, for example mechanical keys or capacitive keys, the latter being preferred. The body preferably comprises an elongated ergonomic shape similar to that of acoustic wind instruments such as, for example, a clarinet, a trumpet or a saxophone. Other forms, however, remain possible.
    [0006] In the remainder of the description, the term instrument defines the electronic wind musical instrument according to the invention, unless otherwise indicated. The instrument includes a mouth (or mouthpiece) in which the musician breathes. This mouthpiece is configured to provide an appropriate mouthing and comprises an inlet port having a cross section preferably of the order of 5 mm 2 to 20 mm 2, which is comparable to a mouthpiece of an acoustic instrument. A duct is connected to the mouth and opens on the outside of the instrument. Thus, the air blown into the mouth can be evacuated from the instrument. In addition, at least one pressure sensor is configured on the conduit to be deformed under the action of the breath, and an electronic processing system is connected to the keys and the pressure sensor. This electronic processing system is configured to produce musical notes depending on the contacts or signals generated by key manipulation and by the at least one pressure sensor that deforms during a breath and provides a measure of the intensity of the breath. Remarkably, the conduit comprises an inlet tube to which is connected the mouthpiece, an outlet tube which opens at the end of the instrument, and an intermediate chamber arranged between said inlet and outlet tubes. . These three elements are configured to pressurize the chamber when blowing into the mouth. In addition, the chamber comprises on its contour a first measurement port on which is connected the pressure sensor disposed outside said chamber.
    [0007] The aforementioned characteristics of the instrument make it possible to maintain a section of the inlet tube which corresponds to that of the tube or cone of an acoustic wind musical instrument, for example a clarinet, a saxophone or a trumpet which communicates with the inlet section on the mouth (or spout). For this, the section of the inlet tube has a diameter of preferably between 10 mm and 30 mm. This inlet tube 15 opens into the chamber, of larger section than the inlet tube or, at the limit, of identical section. This avoids any harmful influence of the chamber on the propagation of the volume of air blown inside the duct. The measuring chamber is dimensioned in section and volume so as to obtain sensations close to the sensations felt on an acoustic instrument. Thus, it is possible to reproduce the same breath sensation as with an acoustic instrument. While the electronic wind musical instruments of the prior art do not allow to find this feeling of breath since the volume of air blown remains concentrated in the mouth eventually evacuating through an arranged evacuation hole on the latter, or even by a discharge pipe of a very limited section, of the order of 1 mm to 2 mm.
    [0008] Furthermore, according to the invention, the intermediate chamber leads to the outlet tube having a smaller section, preferably between 5 mm and 15 mm. This reduction in section output ensures a rise in pressure in the chamber, which allows to significantly increase the pressure at the first measuring port on which is taken up the pressure sensor. Thus, the pressure sensor 30 can easily measure breath changes in the mouthpiece despite the use of a normal inlet tube section, in the range of 10 mm to 30 mm, ie 3036838 5 comparable to that of an acoustic instrument. The musician can therefore reproduce a breath similar to that practiced on a wind acoustic instrument. In addition, the breath change measurements allow the electronic processing system to produce a variable sound once the note is triggered, said processing system being configured for this purpose.
    [0009] Preferably, the length of the chamber is between 20 cm and 50 cm, and the diameter of the section of the chamber is between 15 mm and 30 mm, which avoids any influence of the section reduction on the tube of the chamber. exit when the musician blows and fills the volume of the room and, thus, allows to have gaming sensations that tend at best to those of an acoustic wind musical instrument. These dimensions are provided by way of example and will be adjusted for each embodiment. In a preferred embodiment of the instrument, the first measurement port is positioned near the inlet tube. This improves the response time when taking a measurement by the pressure sensor. In a preferred embodiment of the instrument, the first measurement port 15 is positioned on the top of the chamber. This avoids the rise of moisture or condensation by the first measuring port connected to the pressure sensor, which reduces the risk of damage to this pressure sensor. The pressure sensor is connected to the first measuring port arranged on the wall of the chamber, by means of a connecting pipe which is arranged perpendicular to the flow of air. The increase in pressure in the chamber advantageously allows the use of a single or differential pressure sensor. The single pressure sensor directly measures the pressure at the first measurement port. The differential pressure sensor measures the difference between the pressure at the first measurement port and the external pressure, which limits the influence of the external conditions. In an alternative embodiment, the instrument comprises a second measurement port, the first measurement port and the second measurement port being positioned on two portions of the conduit having different sections. In addition, the pressure sensor is a differential pressure sensor which measures the difference between the pressures at said two measurement ports. This design advantageously makes it possible to measure the pressure difference between two points of the duct, and to deduce a velocity information from the air flow. In addition, according to this variant embodiment, the instrument may comprise a third measurement-taking orifice arranged on a portion of conduit similar to that of the first or the second measurement-taking orifice, a second differential pressure sensor being connected to this third measurement port makes it possible to measure the difference between the pressure at said third orifice and the external pressure. This third measurement port may possibly be confused with the first or the second measurement port. Thus, this design makes it possible to measure the air flow by pressure difference between two measurement points situated at different sections of the duct, and the addition of the second sensor 10 makes it possible in addition to have the pressure measurement at the same time. one or both of these points being used to generate the sound control signals. There is therefore a pressure measurement which is freed from the influence of external conditions and which is supplemented with an air flow measurement device produced using the differential sensor.
    [0010] In the case where a differential pressure sensor is connected to the first measurement port for measuring the difference between the pressure at the first measurement port and the external pressure, the instrument may comprise, alternatively, a second measurement port and a second differential pressure sensor which is arranged at the second measurement port. This second differential pressure sensor measures the difference between the pressure at the second measurement port and the external pressure. The first and second measurement ports are positioned on two portions of the duct having different sections. This design also makes it possible to measure the pressure difference between two points of the duct and to deduce therefrom a speed information of the air flow, the treatment system 25 recovering the pressure measurements in differential with respect to the outside at the same time. two measurement ports, and then calculating the differential pressure between said two orifices. This device also makes it possible to overcome the influence of external conditions in the measurement of the pressure information. In one embodiment, the instrument includes a system for varying the section of the outlet tube, configured to vary the flow rate at the outlet of the conduit. In addition, the electronic processing system is configured to adapt according to the adjustment of the outlet tube section variation system. This makes it possible to adapt the instrument to the best acoustic wind instrument used by the musician, so that he can progress as if he were practicing on his acoustic instrument. In a preferred embodiment, this variation system of the section of the outlet tube consists of a range of inserts, said inserts comprising exit holes of different diameters. These inserts will form the outlet tube once set up by interlocking on the chamber. In one embodiment, the instrument comprises a system for varying the volume of the chamber. In addition, the electronic processing system is configured to adapt according to the setting of the volume variation system of the chamber. This makes it possible to modify the feeling of play, which allows the instrument to behave like different types of acoustic instruments, for example a clarinet, a trumpet or a saxophone. In a preferred embodiment, the volume variation system of the chamber consists of a range of inserts, the inserts having an identical exit hole, which makes it possible to maintain the same output flow rate. In addition, these inserts are of different lengths, so as to fill more or less the chamber and thus change its volume.

FIGS. 6A and 6B schematize a conduit of an object of the invention, showing a system of variation of the tube section Release ; FIGS. 7A and 7B schematize a conduit of an object of the invention, showing a system for varying the volume of the chamber. DETAILED DESCRIPTION The following description will attempt to describe in particular the design of the duct and the implementation of the pressure sensor or sensors on this duct. In the following description, the same references will be used to describe the same elements or their equivalents according to the different embodiments. In Figures 1 to 3, the instrument 1 comprises a body 2 on which are arranged keys 3, said elements being illustrated in drawn lines. The shape of the body 2 and the positions 5 of the keys 3 may be various and, for example, will correspond to those of acoustic wind musical instruments, such as a clarinet, a saxophone, a trumpet or others. Preferably, the keys 3 are capacitive type, for generating signals or electrical pulses at the touch of the fingers on the keys. However, one could provide keys 3 of the mechanical type or any other technology for detecting the presence of a finger, without departing from the scope of the invention. The instrument 1 comprises a mouth 4 (or mouthpiece) in which the musician blows. The shape of the mouth 4 will correspond, for example, to that of the acoustic wind musical instrument also practiced by the musician. Other types of mouths are conceivable, possibly a mouth remote from the body of the instrument and 15 connected thereto by means of a flexible or rigid pipe. This mouth 4 has an inlet 4a and is connected to a conduit 5 which preferably extends over the length of the body 2 of the instrument 1, as illustrated in Figures 1 to 3. When the musician blows into the mouth 4, the air enters through the inlet 4a and then propagates in the conduit 5. This inlet 4a has an air passage section of the order of 5 mm 2 at 20 mm2, which is comparable to a mouthpiece of an acoustic instrument. As illustrated in Figures 1 to 4, the duct 5 comprises an inlet tube 6 constituting the upstream portion of said duct 5, the mouth 4 being connected to the inlet tube 6, for example by interlocking. This inlet tube 6 comprises a section which is preferably circular and of a diameter of between 10 mm and 30 mm, this section corresponding substantially to that of an acoustic wind musical instrument. The duct 5 also comprises a chamber 7 which extends the inlet tube 6, this chamber 7 constituting an intermediate portion of said duct 5. In FIGS. 1, 2 and 4, the chamber 7 comprises a larger section than the duct. 6. In FIG. 3, the chamber 7 comprises a section identical to that of the inlet tube 6, which is a limit, the upstream section reduction being in this case directly integrated into the mouthpiece 4. In this configuration of Figure 3, the inlet tube 6 and the chamber 7 merge. As illustrated in FIGS. 1 to 4, the duct 5 also comprises an outlet tube 8 disposed in the extension of the chamber 7, this outlet tube 8 constituting the downstream portion of said duct 5. The outlet tube 8 comprises a section smaller than that of the chamber 7, the section restriction ensuring a rise in pressure in said chamber 7.
    [0011] Preferably, this section of the outlet tube 8 is circular and has a diameter of between 5 mm and 15 mm. The chamber 7 comprises a section which, preferably, is circular and between 15 mm and 30 mm. In addition, this chamber 7 has a length of between 20 cm and 50 cm. This design advantageously makes it possible to increase the pressure in the chamber 7 sufficiently to allow pressure measurements to be made by means of basic pressure sensors, such as a simple pressure sensor or a differential pressure sensor, such as the description below. next specifies it. In addition, this design makes it possible to increase the dynamics of the pressures observed in the duct 5, bringing them into more easily measurable ranges of values, which makes it easier to distinguish the blast variations of the musician in the mouthpiece 4. This design also allows the blast of air to propagate along the duct without any brake related to the presence of a restriction in the duct 5, the retention of a section of the inlet tube 6 similar to that of an acoustic wind musical instrument making it possible to preserve the same sensations as with said acoustic instrument.
    [0012] As illustrated in FIG. 1, the chamber 7 comprises in its upstream part a first measurement port 9, to which a pressure sensor 10 is connected via a pipe 11. This pressure sensor 10 may be a simple pressure sensor directly measuring the pressure at the measurement port 9. This pressure sensor 10 may alternatively be a differential pressure sensor measuring the difference between the pressure at the pressure port 10 and the pressure sensor 10. the level of the measuring orifice 9 and the pressure outside the instrument 1. This pressure sensor 10 emits a signal proportional to the measurement made, this signal being transmitted to a processing system 12 through 13. The keys 3 are also connected to the processing system 12 by means of electric cables 14, these keys 3 transmitting electrical signals 30 to said processing system 12 when in contact with the fingers of the musician. It is also possible to envisage this embodiment of FIG. 1, with a duct 5 which has an inlet tube 6 and a chamber 7 of identical sections, said elements being merged 3036838 10 and forming the pressurization chamber connected directly to the mouth 4 which has a reduction of section to its inlet 4a. In the variant illustrated in FIG. 2, in addition to the first measuring orifice 9 arranged upstream of the chamber 7, the duct 5 comprises a second measuring orifice 15 which is arranged on the inlet tube 6. in addition to the pressure sensor 10 is a differential pressure sensor which is connected, on the one hand, to the first measuring port 9 through the pipe 11 and, on the other hand, to the second measuring port 15 through a second hose 16. The pressure sensor 10 measures the pressure difference between the pressure at the first measurement port 9 and at the second measurement port 15. This sensor pressure 10 is connected to the treatment system 12. The second measuring orifice 15 may be arranged at other locations on the duct 5, for example downstream of the chamber 7. In the variant illustrated in FIG. measuring tap 9 is arranged upstream of the chamber 7 which, as explained above, integrates the inlet tube 6.
    [0013] A second measuring port 15 is arranged, for example, downstream of the chamber 7. In addition, a first pressure sensor 10 is connected to the first measurement port 9 via the pipe 11 and a second The pressure sensor 17 is connected to the second measurement port 15 via a pipe 18, these two pressure sensors 10, 17 being differential pressure sensors, each connected to the processing system 12 through of electric cables 13, 19. The first pressure sensor 10 measures the pressure difference between the pressure at the first measurement port 9 and the outside of the body 2 of the instrument 1. second pressure sensor 17 measures the pressure difference between the pressure at the second measurement port 15 and the outside of the body 2 of the instrument 1. This design allows to have the pressure in the chamber in two points of the chamber 7, but also the pressure difference between these two measuring points. In the variant of FIG. 4, the instrument 1 has all the characteristics previously described for FIG. 2, and additionally comprises a third measurement port 9 'which is connected to a second differential pressure sensor 17 by means of FIG. This second differential pressure sensor 17 measures the pressure difference between the pressure at the third measurement port 9 'and that outside the body 2 of the instrument 1. This third measurement port 9 'is disposed near the first measurement port 9, on a portion of the conduit 5 of identical section. This design makes it possible to have the pressure difference between these two measurement points, as well as the pressure near one of these two measurement points.
    [0014] It could also be envisaged to confuse the third measurement port 9 'with the first measurement port 9. Similarly, it could be envisaged to position this third measurement port 9' in the vicinity of the second set port According to these variants illustrated in FIGS. 1 to 4, the processing system 12 is configured to process the data received from the pressure sensor (s) 10, 17 and the keys 3, and to output a response curve. similar to that of the acoustic response of an acoustic wind musical instrument. By way of example illustrated in FIG. 5, the processing system 12 comprises a first cell 20 processing the signals of the pressure measurements coming from the pressure sensor or sensors 10, 17, for example a signal conditioning circuit which may comprise means for adapting the signal dynamics to an analog-to-digital converter. Similarly, the processing system 12 comprises a second cell 21, for example a capacitive key sensing circuit using CITouch® technology from Atmel®, transmitting information during contact with the fingers on the keys 3 of the instrument 1, when these 20 keys 3 are capacitive type. These cells 20, 21 then transmit the data to a microcontroller-type computer 22, which integrates a computer program making it possible to restore the sound response curve as a function of the received data. Numerous variants within the reach of those skilled in the art are possible, depending on the technologies used for the pressure sensors 10, 17 and for the keys 3, these components being able to directly integrate technologies configured to transmit the information directly to the computer. The computer 22 can also directly integrate technologies and / or program complements for processing the information of said components. When the musician is blowing into the mouthpiece 4 and manipulating the keys 3, the program is configured to determine the measure from which to trigger a new musical note and the measure from which to stop it, using all the values. intermediates to vary the expression of the sound reproduction by playing on the sound volume but also on other timbre elements of the sound produced.
    [0015] The program may also be configured to perform more elaborate treatments to simulate the physical behavior of an acoustic instrument. The capacity of the instrument 1 to increase the dynamics of the observed pressures enables the computer 22 to vary this response curve as a function of the variations of the blast 5 in the mouthpiece 4. This response curve is then processed by a third cell of FIG. processing 23, sound synthesizer type that can be hardware or virtual (software running on a computer), associated with a sound reproduction device ranging from simple amplifier / headphone pair to the complex sound system. This processing cell 23 renders signals and transmits them to a loudspeaker 24 via an electrical cable 25, as illustrated in FIGS. 1 to 4 and 6. The person skilled in the art is able to program the computer 22 to restore the sound response curve. In a variant of the instrument 1 according to the invention, it comprises a system for varying the section of the outlet tube 8, as illustrated in FIGS. 6A and 6B. In FIG. 6A, the duct 5 comprises a first insert 26a which constitutes the outlet tube 8. This insert 26a is fitted into the chamber 7 over a length 11 and comprises a through hole 27a with a diameter d1. In FIG. 6B, a second insert 26b is fitted into the chamber 7 instead of the first insert 26a of FIG. 6A, this second insert 26b also comprising a length 11 and a through hole 27b having a diameter d2 different from the diameter. dl. The flow rate in the outlet tube 8 is thus adapted as a function of the insert 26a, 26b used. The instrument 1 will use in this case the setting means of the processing system 12 to adapt the behavior of said processing system according to the insert 26a, 26b used. Thus, the instrument 1 can be adapted as best as possible to the acoustic wind instrument used by the musician. In a variant of the instrument 1 according to the invention, it comprises a system for varying the volume in the chamber 7, as illustrated in FIGS. 7A and 7B. In FIG. 7A, the duct 5 comprises a first insert 26c which constitutes the outlet tube 8. This insert 26c is fitted into the chamber 7 over a length 12 and comprises a through hole 27c with a diameter d3. Thus the chamber 7 comprises a first volume V1. In FIG. 7B, a second insert 26d is fitted into the chamber 7 instead of the first insert 26c of FIG. 7A, this second insert 26d comprising a length 13 different from the length 12. of the first insert 26c, and a through hole 27d also of a diameter d3. Thus, the chamber 7 includes a second volume V2. The variation in volume in the chamber 7, thanks to the use of such inserts 26c, 26d, advantageously makes it possible to modify the feeling of play when the musician blows into the instrument 1. Thus, the instrument 1 can be adapted to different types of instruments, for example clarinet, trumpet or saxophone.
    [0016] The instrument 1 will use in this case the setting means of the processing system 12 to adapt the behavior of said processing system according to the insert 26c, 26d used. One could also provide an instrument variant 1 combining the variation systems of the section of the outlet tube 8 and the volume of the chamber 7, described above. For example, in the embodiment of Figures 6A and 6B, the second insert 26b would have a length different from the length 11 of the first insert 26a. Or, in the embodiment of FIGS. 7A and 7B, the second insert 26d would have a different diameter than the diameter d3 of the first insert 26c. The foregoing detailed description of alternative embodiments of the instrument 1 is not limiting in any way. On the contrary, it aims to remove any imprecision as to its scope. Thus, numerous variants may be envisaged within the scope of the invention, in particular as regards the position of the measurement ports 9 and 15. Their positioning upstream of the chamber 7, as illustrated in FIGS. The advantage of improving the response times by decreasing them, when taking a measurement by the pressure sensor 10. Preferably, the measurement ports 9, 15 will be positioned on the upper side of the chamber 7 to to prevent the rise of humidity in the pressure sensor or sensors 10 and 17. The dimensions of the inlet tube 6, the chamber 7 and the outlet tube 8, as well as the passage section of the inlet orifice 4a of the mouth 4, may be adapted according to the type of acoustic wind musical instrument 25 to which the instrument 1 must stretch.
