    专利说明:

    The invention relates to a magnetic pickup for a stringed instrument having at least one string, wherein the stringed instrument comprises a neck portion and a body comprising an instrument panel, and wherein the north and south pole of the magnetic sampler defines a magnetic axis.
    Known electric stringed or stringed instruments, in particular electric violins or electric guitars, have the disadvantage of a relatively weak, interference-prone and distorted sound pickup signal which does not allow high-quality signal and sound processing.
    The object of the invention is therefore to provide a magnetic pickup of the type mentioned above, with a stronger pickup signal and thus a higher noise signal distance in the sensed signal can be achieved.
    According to the invention this is achieved in that the magnetic axis of the magnetic pickup is aligned substantially parallel to the instrument cover, or that in the region of the magnetic pickup an auxiliary magnet is arranged with a magnetic axis, wherein the magnetic axis of the auxiliary magnet substantially parallel to the instrument ceiling or at a right angle to Magnet axis of the magnetic pickup is aligned.
    In the first variant of the invention, the magnetic pickup is aligned with its magnetic axis so that it lies in the vibration plane of the respective string, which is excited by the arc approximately parallel to the instrument panel to vibrate. As a result, the signal obtained in the magnetic pickup element according to the invention achieves a correspondingly high signal strength.
    In the second alternative variant, an auxiliary magnet is used to generate a magnetic field component in the vibration plane of the respective string, and thus to achieve a stronger induction effect in the magnetic pickup according to the invention.
    In both variants of the invention, a higher signal strength and thus less influence of interference signals and high fidelity can be made possible.
    A further development of the first variant of the invention can consist in that, furthermore, the magnetic axis of the at least one magnetic pickup is oriented substantially at a right angle to the string in order to ensure the highest possible and unadulterated signal generation.
    A further embodiment of the first variant of the invention may consist in that the stringed instrument has two or more strings, and that the one or more magnetic pickup is or are each arranged between two of the strings whose or their magnetic axis parallel to the instrument cover and thus in the Vibration level of the strings is.
    In this case, the magnetic pickup in a conventional manner comprise a cylindrical permanent magnet core with a wound around the magnetic core winding for signal pickup, wherein the cylinder axis is the magnetic axis, wherein the. Winding is accommodated in a bobbin, which is formed from a cylindrical pipe section with end flanges, and wherein the cylindrical permanent magnet core is arranged in the pipe section of the bobbin.
    In a preferred form, in the first variant of the invention, the magnetic pickup can each be arranged such that it protrudes from the instrument cover or the fingerboard in order to thus achieve a suitable orientation of the magnetic axis of the magnetic pickup.
    In a further embodiment of the first variant of the invention, the magnet or the magnetron can be mounted on the fingerboard or partially inserted in this, so that the magnetic axis - seen in cross-section - is oriented substantially parallel to the tangent to the respective part of the curved surface of the fingerboard.
    In this way, the magnetic axis of the respective
    Magnetronabnehmers substantially aligned so that it lies in the plane of vibration of the arc excited string and thus can form a very strong and undistorted pickup signal.
    By contrast, an advantageous development of the second variant of the invention can be that the magnetic pickup is embedded in each case in a recess of the instrument cover or the fingerboard below the at least one string, and that the side of the at least one string a protruding bracket is arranged, on which the respective Auxiliary magnet is arranged, whose
    Magnetic axis is oriented substantially parallel to the instrument cover or to the fingerboard.
    By this arrangement of a projecting from the instrument ceiling auxiliary magnet allows the generation of a magnetic field component in the plane of vibration of the excited string of a bow, so that in the known manner arranged Magnettonabnehmer due to the additional magnetic field of the auxiliary magnet, a greater strength of the sensed signal can be achieved.
    An alignment of the magnetic axis of the respective auxiliary magnet substantially at a right angle to the string is also helpful.
    According to a preferred embodiment of the second variant of the invention, the respective auxiliary magnet may be a permanent magnet, which preferably has a cylindrical shape, so that the cylinder axis is the magnetic axis. It may be within the scope of the invention, the auxiliary magnet also e.g. to be an electromagnet.
    The invention further relates to an electric stringed instrument with one or more magnetic pickups according to the invention.
    According to one embodiment of the invention, the electric stringed instrument can be an electric violin without limiting the generality. , The invention will be explained in detail with reference to the embodiments illustrated in the drawings. It shows

    Fig.l shows a section through a known electric stringed instrument with a magnetic pickup 1, which is arranged below a string 10 and the north and south pole defining a magnetic axis 80.
    Hereinafter, the invention will be exemplified by, but not limited to, an electric violin or violin as a stringed instrument. However, the invention may be applied to any stringed instrument or stringed instrument, e.g. Cello, viola, guitar etc. are used. Similarly, the type, the number of strings of the string or string instrument in which the magnetic pickup according to the invention is installed is subject to no restriction. A subsequent installation of the magnetic pickup according to the invention in a string or string instrument is possible.
    The magnetic pickup 1 has a cylindrical permanent magnet core 40 with a wound around the magnetic core 40 winding 41 for signal pickup, wherein the cylinder axis 80 is the magnetic axis. The magnetic core has opposite magnetic poles S and N at its ends, which define the magnetic axis.
    The winding 41 is accommodated in a bobbin, which is formed from a cylindrical tube section 52 with end flanges 50, 51, wherein the cylindrical permanent magnet core 40 is disposed in the tube section 52 of the bobbin. The type of magnetic pickup shown in Fig. 1 is given only by way of example and serves to explain the operation. , The permanent magnet core generates a static magnetic flux that flows from the north pole N to the south pole S. If the string 10 oscillates in front of the pole S of the pickup 1, this magnetic flux changes and a voltage is induced in the winding 41 that corresponds to the string vibration and can be amplified in a subsequent amplifier (not shown).
    2 shows an embodiment of a stringed instrument according to the invention, in particular stringed instruments, in particular a violin, of which a fingerboard 77 is shown, above which four strings 10, 11, 12, 13 are stretched.
    According to the Invention, the magnetic axis 80 of two magnetic pickups 2, 3 is substantially parallel to
    Instrument cover 70 aligned, due to the
    Attachment of the magnetic pickup elements 2, 3 on the curved surface of the fingerboard 77 no exact parallel position of the magnetic axis 80 and the instrument endecke 70 is given.
    The magnetic axes 80 of the magnetic pickups 2 and 3 positioned between each two strings 10, 11 and 12, 13 are arranged in this way approximately in the vibration plane of the strings 10, 11 and 12, 13, so that a much stronger signal than in the state of the art The art known arrangement according to Fig.l can be achieved. Each magnetic pickup 2, 3 can record a signal of the nearby oscillating string 10, 11 on both respective pole sides.
    The orientation of the magnetic axes according to the invention requires that the magnetic pickups 2, 3 project from the instrument cover 70 or the fingerboard 77. The magnetic pickup elements 2, 3 are mounted on the fingerboard 77 by being partially inserted therein, so that the magnetic axis 80 is oriented substantially parallel to the tangent to the respective part of the curved surface of the fingerboard 77, as viewed in cross section.
    In the exemplary embodiment according to FIGS. 3 to 7, a violin with four strings 10, 11, 12, 13 is again formed, which are stretched over a web 71 and over the fingerboard 77. Neck and body of the violin are not shown. With a violin bow 73, which comprises a rod 74 and a covering 75, the four strings 10, 11, 12, 13 can be made to oscillate in a region of the violin facing the strings 10, 11, 12, 13 in the longitudinal direction
    Magnetic pickups 21, 22, 23, 24, 25 offset, as out
    Fig.3 and Fig.4 shows.
    In the plan view according to FIG. 5 and FIG. 6, the maximum deflections occurring in the execution of a vibration of the string 10 are shown in dashed form. Due to the substantially parallel orientation of the magnetic axis 80 of the magnetic pickup 21 to the underlying instrument cover, the magnetic axis 80 lies exactly in the vibration plane of the string 10, so that the field changes of the magnetic field generated by the magnetic core 40 is very strong and the signal induced in the winding 41 is very large , which can be sensed at winding terminals 42.
    In Fig. 7, the orientation of the poles S, N of the respective Magnettonabnehxner 21, 22, 23, 24, 25 is shown. Each of the four strings 10, 11, 12, 13 is arranged between in each case two of the magnetic transducers 21, 22, 23, 24, 25, so that mutually facing sides of the magnetic transducers 21, 22, 23, 24, 25 have the same magnetic polarity. For example, e.g. the string 11 is arranged between the magnetic transducers 22, 23, wherein the mutually facing sides of the magnetic transducers 22, 23 have the same magnetic polarity S, S.
    The Windungsanschlüsse 42 of the magnetic pickups 21, 22, 23, 24, 25 are electrically connected in parallel and can be supplied in this way a single amplifier. The deflections of the strings 10, 11, 12, 13 are received in both directions by the respectively adjacent Magnetettonaufnehmern 21, 22, 23, 24, 25 and converted into an electrical signal, which is amplified as a result.
    FIG. 8 shows the oscillatory movement achieved by the arc 73 during the oscillation excitation of the string 13, wherein the magnetic axes 80 of the magnetic pickups 24, 25 lie approximately in the oscillation plane of the string 13.
    9 shows a further embodiment of the string instrument according to the invention with four strings 10, 11, 12, 13, 14 and three between the strings 10, 11, 12, 13, 14 arranged Magnettonaufnehmern 21, 22, 23, wherein according to the invention, the magnetic axis 80th each substantially parallel to the instrument panel 70.
    10 shows a further embodiment of the stringed instrument according to the invention with five strings 10, 11, 12, 13, 14 and four magnetic magnet receivers 21, 22, 23, 24 arranged between them, in which the magnetic axis 80 is each substantially parallel to the instrument panel 70.
    In the further embodiment of the invention shown in Fig.ll to 14 according to the invention, in addition to the magnetic pickups 102, 103, 104, 105 auxiliary magnets 61, 62 arranged with a magnetic axis 81 which is aligned substantially parallel to the instrument cover 70, while the magnetic axes of the Magnetic pickup 102, 103, 104, 105 are oriented in a known manner approximately normal to the instrument cover 70.
    The auxiliary magnets 61, 62 are designed as permanent magnets, each having a cylindrical shape, so that the cylinder axis is the magnetic axis.
    The magnetic pickups 102, 103, 104, 105 are embedded in a recess of the fingerboard 77 below the strings 10, 11, 12, 13, 14. Winding terminals 42 are connected in parallel and may be supplied to an amplifier, not shown, for amplifying the sensed signal.
    For attachment of the auxiliary magnets 61, 62 of the strings 10, 11, 12, 13 or between each of which a protruding support is arranged, on which the auxiliary magnets 61, 62 are arranged so that the magnetic axis thereof is substantially parallel to the instrument cover 70th or to the fingerboard 77 oriented.
    Further, the magnetic axes 81 of the respective auxiliary magnets 61, 62 are aligned substantially at a right angle to the SaitenlO, 11, 12, 13, 14 (Figure 12), in order to achieve the highest possible symmetry in the tone generation.
    In essence, the field of the auxiliary magnets 61, 62 aligned in the plane of vibration of the strings 10, 11, 12, 13, 14 produces a magnetic field component which causes an increase in the pickup signal induced in the magnetic pickups 102, 103, 104, 105.
