    Noise suppressing device The present invention relates to a noise suppressing device,in particular to such device for use with a microphone devicemounted on and along the length a cable, especially a cablefor use with a mobile communication device.
    For such mobile communication devices, such as mobile phones,it is commonplace to use a cable arrangement, connected tothe device, including a microphone and/or an earpiece orheadset loudspeaker for use when communicating using thedevice. The loudspeaker is connected to one end of the cable,and the other end of the cable is connected to the mobiledevice. The microphone is mounted along the cable, in orderto be arranged in proximity to the mouth of the user whenspeaking into the microphone during communication.Since the said device is for mobile communication, in manycircumstances there is a problem with wind noise interferingwith the quality of the sound captured by the microphone.
    In order to suppress such wind noise, it is known to use apiece of foam material surrounding the microphone. US7,496,208, for instance, discloses a two-part foam piece for such use with a conventional microphone.
    For the specific application of a microphone arranged along acable, US 8,l70,257 discloses a shell-like structure with an internal foam material for mounting on such a microphone.
    The latter solution suffers from a number of drawbacks.
    Ansökningstextdocx 2014-02-21 130056SE Firstly, it would be desirable to provide a wind noise sup-pressing device which only interferes with the quality ofcaptured sound to a minimum degree.
    Secondly, it would be desirable to provide such a devicewhich allows full access to functional interface parts, such as buttons, on the microphone. Such parts are frequently arranged for controlling earpiece sound volume, to answerincoming calls, and so on.Thirdly, it would be desirable to provide a light-weightnoise suppressing device, since the microphone is frequentlyused in a free-hanging position from the head, ear or cloth-ing of a user, which makes weight critical for the user expe-rience.
    Fourthly, it would be desirable to provide a noise suppress- ing device which is inexpensive to manufacture.
    The present invention solves the above described problems.Hence, the invention relates to a noise suppressing devicefor use with a microphone device mounted on and along thelength of a cable, which microphone device comprises a micro-phone, wherein the device is arranged to be mounted on thecable by squeezing action by first and second fastening meansagainst the cable on a first and second side, respectively,of the microphone device, so that, when in this mountedstate, it is arranged around and encloses the microphonedevice, thereby suppressing disturbing noise during soundrecording by the microphone, which device further comprises afoam part which is arranged to cover the microphone when thedevice is in the mounted state, which device is characterised in that the device further comprises a cage-like structure Ansökningstextdocx 2014-02-21 130056SE which is made from rigid material and which, in the mounted state, is arranged to be positioned around the foam part,keeping it in its position covering the microphone whilestill exposing the foam part through holes in the cage-likestructure.
    In the following, the invention will be described in closerdetail, partly in connection to the enclosed drawings, inwhich: Figure l shows a noise suppressing device according to afirst exemplifying embodiment of the invention, in a state inwhich it is mounted on a cable with a microphone, in a per-spective view; Figure 2 shows the same device as figure l, but from a dif-ferent angle and without the cable;Figure 3 shows the same view as figure l, but with a piece offoam removed; Figure 4 is the same view as figure 3, but with a top portionof a cage-like structure removed; Figure 5 is a top view of the noise suppressing device in thepartly removed state which is also shown in figure 4; Figure 6 shows a noise suppressing device according to asecond exemplifying embodiment of the present invention; andFigure 7 shows the device of figure 6 in an exploded view.Hence, figures l-5 show the same noise suppressing device butfrom different angles and/or with different subparts removed.Furthermore, figures l-5 share the same reference numerals.Figures 6-7 share the same reference numerals as figures l-5for the corresponding parts, but the reference numerals offigures 6-7 start with “2” while the corresponding numerals in figures l-5 start with “l”.
    Ansökningstextdocx 2014-02-21 130056SE Figures 1-5 show a noise suppressing device 100 for use with a microphone device 10 (see figure 3) mounted on and along the length of a cable 11. Only a part of the cable 11 isshown in the figures. The microphone device 10 comprises a microphone 12, arranged to capture ambient sound, such as speech from a user communicating using a mobile device (notshown) to which the cable 11 is connected at a distal end,and to convey such captured sound to such mobile device viathe cable 11, as an electric signal. In the figures, themicrophone device 10 and the microphone 12 are shown as oneand the same part. However, it is realized that the micro-phone 12 in general is comprised in the microphone device 10,such as being arranged in the form of one or several sound-capturing holes of a casing of the microphone device 10 incombination with conventional microphone parts, such as amembrane, arranged inside said casing.
    The device 100 is arranged to be mounted on the cable 11 bysqueezing action by first 101 and second 102 fastening meansagainst the cable 11 on a first and second side, respective-ly, of the microphone 12. Figure 1 shows the device 100 insuch a mounted state on the cable 11, in which the device 100is arranged around and encloses the microphone device 10,thereby suppressing disturbing noise during sound recordingby the microphone 12, such as wind noise. In the particularcase in which the microphone 12 is arranged as a distinctsubpart arranged across a certain part of the surface of themicrophone device 10, it is preferred that the device 100completely encloses the surface part of the microphone device10 occupied by the microphone 12, so as to provide efficientnoise reduction.
    Further according to the invention, the device 100 comprises at least one foam part which is arranged to cover the micro- Ansökningstextdocx 2014-02-21 130056SE phone 12 when the device 100 is in the said mounted state. Inthe particular above-described case in which the microphone12 occupies a certain part of the surface of the microphone device 10, this surface part will be completely covered by the said foam part.
    In the figures, the foam part comprises a lower 140 and an upper 150 foam part, covering the microphone 10 device on one side each. In particular, it is preferred that the foam part completely covers, or at least covers essentially the whole length of, the microphone device 10. Suitable materials for the foam part comprise polyurethane (PU), polyethylene (PE), foam rubber (EPDM semi closed cell, PVC, NBR and CR) and cellulose, with preferred densities of 25-130 kg/må bly 60-130 kg/m3. prefera-It is preferred that the area of the foampart arranged to cover the microphone 12 is 2-4 mm thick.Such combinations of materials, densities and thicknesseshave been found to produce adequate noise reductions whilemaintaining good sound quality for voice communications usinga conventional mobile phone.According to the invention, the device 100 further comprisesa cage-like structure which is made from rigid material andin the said mounted state, which, is arranged to be posi- tioned around the foam part 140, 150, keeping it in its posi-tion covering the microphone 12 while still exposing the foam150 through lower holes 116, 117, 118, 119, 127, 128, part 140, and upper holes 126, 129 in the cage-like structure. Inthe case in which the microphone 12 occupies a distinct partof the surface of the microphone device 10, it is preferred that the majority, preferably the whole, of such distinct surface part is located below areas of the cage-like struc- ture where there are such holes 116-119, 126-129 arranged, so Ansökningstextdocx 2014-02-21 130056SE that only foam, as opposed to material of the cage-like structure, covers the microphone 12.
    Such a noise suppressing device 100 will, due to the factthat no rigid part covers the microphone 12, or at least thatthe microphone device 10 in said mounted state is accessiblefrom the outside via at least one, preferably several pathsvia only foam and no rigid parts, will interfere with thequality of captured sound to a minimum degree. To this end,it is furthermore preferred that the said holes 116-119,126-129 cover at least approximately 25%, preferably at leastapproximately 50%, of the total external surface of the de-vice 100.Furthermore, such a device can be made very light-weight,since the foam itself does not add much weight to the light-weight cage-like structure. It can also easily be designed ina way which makes it inexpensive to manufacture, since it canbe made from a very limited number of assembled parts frominexpensive materials. See below for further details.As shown in the figures, the said cage-like structure com-prises several lower beams 111, 112, 113, 114, 122, 123, 124, 125, 115 and sever-al upper beams 121, running across themicrophone device 10 when the device 100 is in the mountedstate, said holes 116-119, where said beams are separated one from the other by126-129.There are preferably at least four, more preferably at least six, more preferably at least eight, such holes delimited by and arranged between said beams.It is preferred that the beams 111-115, 121-125 are arranged to run essentially perpendicular to the longitudinal direc- Ansökningstextdocx 2014-02-21 130056SE tion of the cable 11, and the beams lll-ll5, as shown in the figures,121-125 are preferably substantially parallel. Inthis case, and as also shown in the figures, it is preferredthat such perpendicular beams are adjoined by respective longitudinal beams 103, 104 running in the same longitudinaldirection along each respective side of the microphone device 10.
    It is further preferred that the device 100 is arranged with a generally elongated shape, preferably extending, in the mounted state, in the longitudinal direction of the cable 11,and in particular of the microphone device 10, which micro- phone device 10 also may be generally elongated.
    Such a device 100 has been found to display high strengthwhile still providing the above discussed adequate noisesuppression in combination with high sound quality.
    According to a preferred embodiment, the device 100 comprisespositioning means arranged to control the position of thedevice 100, along the longitudinal direction of the cable 10,in relation to the microphone device 10, when the device 100is in the said mounted state.
    Such positioning means are preferably arranged so that, whenthe device 100 is in the mounted state, the longitudinalposition of the device 100, along the longitudinal directionof the cable 11, in relation to the microphone device 10, isfixed to a predetermined such longitudinal position. Hence,the said position control is preferably imparted by the posi-tioning means by the positioning means not allowing the de-vice 100 to be mounted into the above said mounted state onthe microphone device 10 unless the said positioning require- ment is met.
    Ansökningstextdocx 2014-02-21 130056SE It is preferred that the positioning means are tailored forone or several specific microphone device makes, for instanceby the design of the cage-like structure being carefullyselected so as to fit a particular model of the microphone device 10.
    This may also include selecting the precise layout and posi-tion of the beams 111-115,121-125, in order to minimize thedisturbance of the microphone 12 for a particular microphonedevice 10. In particular, it is preferred that the cage-likestructure is designed so that none of the beams 111-115,121-125 in the mounted state covers the microphone 12. It isrealized that this particular embodiment is particularlyrelevant for microphone devices in which, unlike the micro-phone device 10 shown in the figures, the microphone occupiesa distinct certain part of the surface of the microphonedevice, as discussed above. For such microphone devices, itis that distinct surface that is not covered by any beams butis directly accessible from the outside via a path only in-volving foam material.
    According to a particularly preferred embodiment, which isalso illustrated in the figures, different ones of said beams111-115, 121-125 are arranged with different stiffness, sothat they deform to a different depth when pressed upon, withequal force, by a user when the device 100 is in the said mounted state. In other words, some less stiff beams are moreresilient under perpendicular pressure than some stifferIn the figures, beams 111, 115, 121,than beams 112-114, 122-124, flexible. beams. 125 are stifferwhich latter are relatively moreIn the shown example, this increased stiffness isaccomplished by a combination of support from end parts of the device 100 and an increased material thickness of the Ansökningstextdocx 2014-02-21 130056SE stiffer beams lll, ll5, thinner beams ll2-ll4, l2l, 125, as compared to the non- supported, l22-l24. However, thestiffness difference could also be accomplished in other ways, such as entirely from a material thickness differenceor a material composition difference, such as arranging lessstiff beams with a central part made completely or partially from a resilient material such as a rubber material.
    It is preferred that the cage-like structure is manufacturedfrom a plastic material, preferably a thermoplastic such as polyamide (PA 6) or acetal homopolymer (POM), both impact modified resistance.
    According to a very preferred embodiment, at least one beamis arranged with a lower stiffness than at least one otherbeam so that, when the device lOO is in the said mountedstate, it covers a button on the microphone device lO suchthat, lOO, when pressed upon by the finger of a user of the devicethe beam in question flexes inwards towards, presses andthereby activates the button in question on the microphone device lO. the microphone device lO comprises three \_|_//), (\_\) In the figures, buttons l3, l4, 15. Buttons l3 ( are for con- trolling the volume of an earpiece attached at a distal endof the exemplifying cable ll, which earpiece is arranged onthe other end of cable ll as compared to the end being con-nected to the mobile device. Button l4 is for responding toincoming voice calls. Other numbers and combinations of but- tons, and corresponding button functions, are of course pos- sible as regards the microphone device lO.
    Beams lll, ll5, l2l, l25 each have a stiffness which is rela- tively high, so that a user pressing down onto one of these Ansökningstextdocx 2014-02-21 130056SE beams with a finger, using reasonable effort, will not result in the beam flexing inwards more than to a limited degree.123 and 124, Beams 122, on the other hand, have a stiffness which is relatively low, so that a user pressing down ontoone of these beams will result in the beam in question flex-ing in towards the microphone device 10, and hence the re-spective button 13, 14, 15 located beneath the flexing beamin question, so that the beam presses the button in andthereby activates a function triggered by pressing the buttonin. It is noted that the distance between the surface of thebutton 13, 14, 15 and the underside of the correspondingflexible beam 122, 123, 124 cannot not be too large in themounted state of the device, such as less than or equal to 5mm thick, preferably 2-4 mm thick, most preferably about 3 mm thick.
    This way, full and easy access to functional parts of the microphone device 10 is provided while yet offering the above discussed advantages in terms of noise shielding, sound qual- ity, manufacturing economy, ergonomics, and so on.
    It is further preferred that at least one, preferably sever- al, preferably all, of the beams 122, 123, 124 in question that are arranged to act on a respective button 13, 14, 15 comprises a respective graphical marking 122a, 124a, (\+// \_\, signify- ing the function respectively) of the button13, 15 which it is arranged to cover when the device 100 is in the said mounted state on the cable 11.
    In the exemplifying embodiment illustrated in figures 1-5,the flexible beam 123 does not feature any marking. Instead,a flat surface 123a centrally located on beam 123, which initself if centrally located on the device 100, can be used as a print surface, for instance for printing a commercial mes- Ansökningstextdocx 2014-02-21 130056SE ll sage in the preferred case in which the device 100 is used asan advertising vehicle.The beams 112, 113, 114 arranged to cover the backside of the microphone device 10, where there are no functional buttons, are preferably relatively stiff. However, in the embodiment described below, according to which the device is composed oftwo identical or substantially identical parts, it is pre-113, 124. ferred that beams 112,123, 114 have the same material prop-erties as beams 122,The above discussed positioning means is, according to apreferred embodiment illustrated in figures 1-5, in particu-lar in figure 5, in the form of a specific distance D betweenthe first 101 and second 102 fastening means, which distanceD is specifically adapted to the length along the cable 11 ofthe microphone device 10, and which essentially correspondsto this length. Hence, in the present example, the fasteningmeans 101, 102 are in the form of a respective hole in eitherend of the device 100, the diameter of which hole is suffi-ciently small so that, when the cable 11 is led through thehole it is held in a predetermined longitudinal positionalong the length of the cable 11 by a pressing force from therespective inner surfaces of the hole in question. It isnoted that the illustrated cable 11 comprises cable connect-ors to the microphone device 10 with a slightly larger diame-ter than the cable elsewhere, and that it is these cableconnectors that are arranged to pass through the respectivehole in the respective short end of the device 100. This may be otherwise for other types of microphone devices 10.
    Since the distance D corresponds to the length of the micro-phone device 11, it is not possible to mount the device 100 without at the same time aligning its position along the Ansökningstextdocx 2014-02-21 130056SE 12 longitudinal direction of the cable 11 so that the buttons13, 14, 123,124. 15 are aligned with the corresponding beams 122, As an alternative, or addition, to this, the alignment means may be in the form of a shape of the inner surface, when in the said mounted state, of the device 100, which shape isspecifically adapted to a corresponding external shape of themicrophone device 10, and arranged to engage with said exter-nal shape, thereby holding the microphone device 10 in itsposition in relation to the device 100. Such shape may forinstance comprise an external corner of the microphone device10 engaging with a corresponding shoulder on the interiorsurface of the device 100, and preferably one such engagementat either side of the device 100 along the longitudinal di- rection of the cable 11.
    As regards the foam part, 150, it preferably comprises two foamsubparts 140, arranged to be positioned on either sideof the microphone device 10 when the device 100 is in thesaid mounted state.
    According to one preferred embodiment, the two subparts 140,150 of the foam part are joined together by a thin bridge,preferably made in the same foam material so that the foampart is constituted by one integrated material part in turn140, 150 and the bridge. comprising the subparts In other words, the foam part is in this case one single material bodywhich can be opened and folded together around the microphonedevice 10, with the two subparts 140, 150 arranged on eitherside of the microphone device 10 when the device 100 is in the mounted state. This provides for easy mounting of thedevice and still keeps the necessary number of parts to a minimum.
    Ansökningstextdocx 2014-02-21 130056SE 13 According to one preferred embodiment, the foam part 140, 150 is not fastened to the cage-like structure in any way, but is only held in position by the beams 103, 104, 121- 125. 111-115,This holds costs down, since the foam and cage-likestructure can be manufactured separately and assembled insidethe cage-like structure when the device 100 is to be used ona particular microphone device 10. the foam However, according to an alternative embodiment, part 140, 150 is permanently attached to the inside of thecage-like structure, 104, such as glued or melted to the inside of the beams 103, 111-115, 121-125. This results in easier assembly.
    In the figures, the cage-like structure comprises a first or bottom part 110 and a second or upper part 120, which are joined together by a hinge means 130, such as a thin plastic material bridge, a hinge or another type of pivotable engage- ment means. The hinge means 130 allows the two parts 110, 120 to be folded together into said mounted state of the device100, in which position the parts 110, 120 are held togetherby a snap lock 131 means arranged on the device 100 opposite from the hinge means 130.
    However, according to an alternatively preferred embodiment, illustrated in figures 6 and 7, the cage-like structure com- prises two separate cage parts 210, 220, arranged to be re- leasably fastened to each other using mutual engagement means231a, 231b, 231c, 231d on the said parts 210, 220 so as to form the device 200 in its mounted state. Figure 6 shows thedevice 200 in this mounted state (however without the micro-phone device and the cable), while figure 7 shows the device 200 exploded for increased clarity. Most of the features Ansökningstextdocx 2014-02-21 130056SE 14 shown in figures 6-7 correspond to features illustrated in figures 1-5, which have already been described in connection to these figures. Therefore, many of these features will not be described again in connection to figures 6-7. In figures 6-7, the foam part is not shown, for reasons of clarity.
    However, it is understood that what has been said about thefoam part in connection to figures 1-5 is also applicable to figures 6-7.
    As seen in figures 6-7, according to a preferred embodiment, the mutual engagement means comprise cooperating snap lock means 231a, 231b on either part 210, 220, preferably in the form of cooperating male 231a and corresponding female 231bsnap lock means. Hence, the parts 210, 220 are not mountedtogether to form the device 200 by folding along a hinged shared edge such as hinge 130, but rather by snapping one of the parts 210 onto the other part 220.
    According to a first alternatively preferred embodiment of such a two-part 210, 220 device 200, which is illustrated in figures 6-7, the two separate cage parts 210, 220 are of identical shape. This makes the device 200 less costly toproduce, since the same machine tool can be used for both220. In this case, 231d, parts 210, it is preferred to use guide means 231c, for instance in the form of cooperatingmale protrusions 231c and corresponding female indentations231d on either parts 210, 220 that cooperate so that the 220 will be allowed to be put together in only one 231d. parts 210,way by the guide means 231c,The particular design illustrated in figures 6-7, with a231b with male snap lock220, in combination of snap lock means 231a,means 231a arranged on either side of both parts 210, combination with guide means 231c, 231d, preferably arranged Ansökningstextdocx 2014-02-21 130056SE as illustrated to act at either end of the longitudinal de- vice 200, has been found to yield a stable and robust con- struction also when using several resilient beams 212, 213, 214, 222, 223, 224 on both cage parts 210, 220.
    According to an alternatively preferred embodiment, the two separate cage parts are of different shape or color. In this case, it is preferred that a first upper cage part, corre- sponding to part 220 in figures 6-7, is adapted to correspondto the specific button layout of a first type of microphone device. Such adaptation comprises, for instance, the arrange-ment of flexible beams at locations corresponding to buttonsarranged on the particular type of microphone device. Fur-thermore, a second upper cage part is adapted to correspond,in an analogous way, to the specific button layout of a sec- ond, different, type of microphone device, alternativelydiffer in coloration from the first that of the upper cagepart.
    Hence, the first and second upper cage parts are of different shape or color, such as comprising different lay- outs of flexible beams. Then, the first upper cage part canbe replaced with the second upper cage part and vice versa,in the sense that the first and second upper cage parts areboth arranged to engage with one and the same bottom cagepart, corresponding to part 210 in figures 6-7. Finally, eachsuch combination between one of said first and second uppercage part and the bottom cage part forms a device accordingto the invention in the said mounted state.
    Hence, there is a common interface comprising the mutual engagement means 231a, 231b, 231c, 231d, for instance com-prising the snap lock means 231a, 231d, 231b and possibly also theguide means 231c, to which common interface standard the said bottom part and all of the said upper parts adhere.
    Ansökningstextdocx 2014-02-21 130056SE 16 Apart from the interface features, the upper parts may differin various ways with respect to their shape and/or color.This way, it is possible to use the same bottom part for manyapplications, effectively saving costs during production.Such different applications may comprise having differentlycolored upper parts, or different upper parts shaped to fittogether with different makes of microphone devices. Prefera-bly, the interior shape of the different upper cage parts aresufficiently similar so as to allow one and the same type ofof the foam part to be used with several, preferably all, different type upper cage parts.The device 100, 200 is preferably between 3 and 7 cm, prefer- ably between 3 and 5 cm, of length, with a cross-section perpendicular to its longitudinal direction, which cross-section is roughly square or at least rectangular, of lessthan 4 cm2.
    Above, a number of preferred embodiments have been described.However, the skilled person realizes that many modificationsmay be made to the disclosed embodiments without departingfrom the central ideas of the invention.
    For instance, the beams illustrated in the figures may verywell be arranged in different patterns while still achievingFurthermore, the aims of the present invention. the position- ing means may also be arranged in other ways.The foam part may be in two parts, possibly permanently fas- tened to the respective cage part, or in one, foldable part, as described above, and the cage-like structure can be in theform of one foldable part or two separate parts. Any combina- tion of these options is foreseeable.
    Ansökningstextdocx 2014-02-21 130056SE 17 Hence, the invention is not limited to the disclosed embodi-ments, but can be varied within the scope of the enclosed claims.
