Description

[0001] SYSTEM FOR MOUNTING A HIGH-FREQUENCY TRANSMITTER BOX ON A WIND INSTRUMENT, ASSOCIATED WIND INSTRUMENT AND MOUNTING SUPPORT

[0002] The present invention relates to a system for attaching a high-frequency transmitter box to a wind instrument, connected by a cable to a microphone mounted on said wind instrument. It also relates to a wind instrument comprising such a fixing system. The invention finally relates to a fixing support for a high-frequency transmitter box, said transmitter box being intended to be connected to a microphone mounted on a wind instrument.

[0003] When performing on stage, musicians typically use microphones to capture the sound of their instruments and then amplify them. For portable instruments, microphones are usually mounted on the instrument, giving the musician more freedom to move around the stage.

[0004] Thus, for wind instruments, for example, it is common to use a microphone that is attached to the bell of the instrument using a clip. For example, there are ranges of clip-on microphones, marketed by the Shure company, under the references BLX, BETA, GLXD or PGA for example, which can be attached directly to the bell of the wind instrument using a clip. All these microphones are connected by a cable to a high-frequency transmitter box, traditionally called a "belt transmitter" because it is intended to be attached to the musician's belt or placed in a pocket of his clothing. The acoustic signals captured by the microphone are converted into an audio signal. The transmitter then allows the audio signals to be sent via a high-frequency radio link to a receiver, which will process them and send them to a mixing desk and / or a speaker intended to amplify them.

[0005] The cable connecting the microphone to the transmitter box is generally between one and one and a half meters long. The cable then dangles between the instrument and the musician's pocket or belt, which creates a risk of the cable getting caught when the musician moves around on stage, which could cause the microphone and / or transmitter box to be torn off. The musician must therefore constantly remain vigilant and pay attention to the cable when playing his instrument.

[0006] It is therefore necessary to limit the size of this cable in order to avoid the risk of the cable getting caught and the microphone and / or transmitter box being pulled out.

[0007] Solutions have been considered to solve this problem. For example, Samson Technologies sells a microphone called Airline AWXm, which includes a transmitter box integrated into the clip that attaches the microphone to the bell. Similarly, there are other microphones with a transmitter integrated into the mounting clip, such as the one called N90 and marketed under the Xiaokoa brand name, or the one called Saxmic-14R marketed under the Soundplus brand name. Another system, called NUX B6 and marketed under the NUX brand name, consists of attaching the microphone to the transmitter box, which includes a flexible attachment, also called a clamp, that fits over the bell of the instrument.

[0008] However, these solutions are not entirely satisfactory. Indeed, the miniaturization of the transmitter, integrated into the microphone clip, implies the elimination of certain functions in the signal processing, which harms the quality of the sound reproduced and is not acceptable for musicians performing in front of an audience. In addition, the clip does not grip the bell sufficiently strongly and is allowed to rotate under the weight of the transmitter box, which leads to poor sound recording since the microphone is no longer optimally positioned in relation to the bell. The assembly consisting of the microphone and the transmitter remains bulky and too prominent, so much so that it risks catching on other instruments or musicians, and possibly being torn off, when the instrumentalist moves while playing. Finally, the integrated microphone and transmitter assembly is so bulky that it deteriorates the visual integrity of the wind instrument.Yet another method considered by many musicians is to attach the transmitter box to the body of the instrument using hook-and-loop and / or elastic straps and to fix the cable, connecting the microphone to the transmitter box, to the instrument with tape. However, this solution amounts to DIY that does not last over time and also distorts the visual integrity of the instrument.

[0009] Furthermore, a video available on the Internet at the following URL: https: / / www.facebook.com / HornDoctor / videos / heres-a-little-geeking-out-about-trombone-counterweights-in-response-to-a-post-o / 45319271973831 1 / and a description of a trombone on the website "le site du trombone" at the following URL: https: / / lesitedutrombone.fr / facture-trombone / , describe the use of steel counterweights for trombone, whose surface is flat, to allow the instrument to be perfectly balanced during use. The counterweight described in these two links is placed on a trombone reinforcement spacer.

[0010] The invention therefore aims to remedy at least one of the drawbacks of the prior art. The invention aims in particular to design a system which allows the attachment of a high-frequency transmitter box, connected to a microphone on board the wind instrument, said system being integrated into the instrument and allowing the box to be attached so that it does not catch and does not risk being torn off and falling when the musician moves, that it does not distort the visual integrity of the wind instrument and whose weight does not disturb the balance of the instrument.

[0011] To this end, the invention relates to a system for fixing, on a wind instrument, a high-frequency transmitter box, said transmitter box being intended to be connected by a cable to a microphone on board a wind instrument, said fixing system being characterized in that it comprises, on the one hand, a fixing support and, on the other hand, a transmitter box, one face of which is provided with a raised element, said fixing support comprising a surface whose shape is complementary to the raised element and being designed to accommodate and hold, by a reversible connection, said raised element of said transmitter box.

[0012] Thus, the fastening system allows the transmitter box to be held securely on the wind instrument, so that the transmitter box becomes one with the instrument and does not risk being torn off due to accidental snagging. The cable length between the microphone and the transmitter box is considerably reduced from a few centimeters to around ten centimeters, so that the cable no longer bothers the musician and no longer risks getting caught or being torn off. Finally, the transmitter box becomes one with the instrument without distorting its visual integrity.

[0013] According to other optional features of the fixing system:

[0014] - the surface of the fixing support is a ferromagnetic surface and the raised element of said transmitter housing is a magnetic pad;

[0015] - said mounting bracket is arranged to accommodate a spacer of said wind instrument and has a thickness dimensioned such that, when the system is mounted on said wind instrument with said transmitter box fixed on said mounting bracket, the total thickness of said system constituted by said mounting bracket with said spacer and said transmitter box, does not protrude from a plane tangent to an external edge of a bell of said wind instrument.

[0016] The invention further relates to a wind instrument comprising a fixing system as described above.

[0017] The invention finally relates to a fixing support for a high-frequency transmitter box, said fixing support being fixed to a wind instrument and being characterized in that it is arranged to accommodate a reinforcing spacer for said wind instrument and in that it comprises a hollow housing in which is arranged a part having a surface arranged to ensure a reversible connection with said transmitter box, the shape of said surface being complementary to a raised element arranged on one face of said transmitter box and with which it is intended to cooperate.

[0018] According to other optional characteristics of the fixing support: - the part with a flat surface is ferromagnetic and the reversible connection is a magnetic connection;

[0019] - it comprises a first part and a second part, mutually arranged to grip the reinforcing spacer of the instrument, said hollow housing being provided in said second part and accommodating a third ferromagnetic part, said first part, said second part and said third part being assembled to each other by screwing;

[0020] - the reinforcing spacer of said instrument is tubular, said first part and said second part both have a groove respectively facing each other and intended to form a channel enclosing said tubular spacer;

[0021] - the reinforcing spacer of said instrument has an annular shape, said first part has a rim on which rests a first surface of said spacer ring and a central part filling a central recess of said ring and flush with a second surface of said ring opposite said first surface of said ring and said second part rests on said second surface of said spacer ring;

[0022] - it further comprises a fourth part forming a reinforcing spacer for said wind instrument, said fourth part having an elongated shape in two parts arranged to cooperate with each other, and having at each of its ends curved edges forming a jaw, said end jaws being arranged to grip two pipes of said instrument and said first part and said second part of said fixing support grip said fourth part forming a spacer;

[0023] - it comprises two tabs positioned opposite each other, said tabs each having curved ends, the curved ends of a first tab being positioned opposite the curved ends of a second tab, and on either side of two pipes of said instrument to grip them and to form a first part of said fixing support incorporating a reinforcing spacer of said instrument, and one of the two tabs of said fixing support is surmounted by a second part having said hollow housing in which is arranged a third ferromagnetic part forming said ferromagnetic surface, said first and second tabs, said second part and said third part being assembled to each other by screwing;

[0024] - said first part and said second part are made of a material different from that of the third ferromagnetic part.

[0025] Other features and advantages of the invention will appear on reading the description given by way of illustrative and non-limiting example, with reference to the appended Figures which represent:

[0036] - figure 9, a perspective view of a portion of bugle equipped with a fixing support according to an alternative embodiment.

[0037] A wind instrument is an instrument whose sound is produced by vibrations of the air contained in its pipes, also called slides. The vibrations of the air are caused by the breath of an instrumentalist. Wind instruments are grouped into two main families: woodwinds, for which the sound is produced by the vibration of a wooden reed, and brass instruments, for which the sound is produced by the vibration of the musician's lips at the mouthpiece of the instrument. Thus, the saxophone, for example, belongs to the woodwind family, while the trombone, trumpet, horn, tuba, bugle, or bugle, for example, belong to the brass family.

[0038] The term "reinforcing brace" of a wind instrument is defined as a part used to stiffen the attachment of at least two pipes of the instrument, such as, for example, the attachment of the bell pipe of the instrument to the main pipe, also called the slide, connected to the mouthpiece or mouthpiece.

[0039] According to the invention, the mounting bracket of the transmitter box is arranged to accommodate a reinforcing spacer for the wind instrument.

[0040] Figure 1A represents a partial view of a saxophone comprising a reinforcing spacer 410. This spacer 410 conventionally makes it possible to stiffen the attachment between the main pipe 460, connected to the mouthpiece of the saxophone, and the pipe of the bell 461 of said saxophone.

[0041] Figure 1B shows an exploded view of a mounting bracket 400 for a transmitter box intended to be connected by cable to a microphone on board such a saxophone and comprising the saxophone reinforcement spacer 410. The saxophone reinforcement spacer 410 is conventionally circular and hollowed out 413 in its center, having the shape of a ring 414. Three tabs 412 with threaded holes are provided for fixing it by screwing to the saxophone.

[0042] This spacer 410 for saxophone is advantageously sandwiched between a first part 420 and a second part 430, said second part 430 having a hollow housing 431 intended to receive a third ferromagnetic plane part 440. Preferably, the three parts are assembled to each other in such a way that they can be easily disassembled. Thus, said first part 420, said second part 430 and said third ferromagnetic part 440 are each provided with a threaded hole in their center, respectively referenced 423, 432 and 441, so as to be able to assemble them to each other by means of a screw 450.

[0043] The first part 420 has a rim 421 on which a first surface of the ring 414 of the reinforcing spacer 410 rests, and a central part 422, intended to fill the empty space 413 in the center of said ring 414 and whose thickness is equal to that of said ring 414, in order to have a flat surface flush with a second surface of said ring 414, opposite said first surface.

[0044] The second part 430 rests on said second surface of the ring 414 of the reinforcing spacer 410 and comprises in its thickness, a hollow housing 431 intended to receive the third ferromagnetic part 440. Optionally, this second part 430 can be provided with blind orifices 433 on its periphery, as shown in FIG. 1 B, in its lower part located under the hollow housing 431. These orifices 433 are regularly spaced along the periphery of the part. Such optional orifices 433 are advantageously provided to lighten the weight of the part. In an alternative embodiment, the second part 430 may have a border around the perimeter of the hollow housing 431 and the blind orifices 433 may be made vertically, regularly spaced along the border surrounding said hollow housing 431 and in the thickness of the second part 430.The third part 440 is in the form of a ferromagnetic metal pellet whose thickness is equal to that of the hollow housing 431, so that its flat surface is flush with the upper edge of the hollow housing 431 of said second part 430.

[0045] Figure 2 illustrates a transmitter box 20, equipped with a high-frequency radio antenna 21 and a connection socket, not shown, intended to allow the connection of the cable coming from the microphone. This transmitter box 20 comprises a magnetic pad 25, fixed by any known means, on one of its faces. Preferably, the magnetic pad 25 is fixed by gluing on one face of the transmitter box. Such a pad can for example be chosen from neodymium magnets, such as those marketed under the trademark Maul for example, Alnico magnets manufactured from metal alloys mainly consisting of cobalt, nickel, aluminum and iron or even samarium-cobalt magnets. One face of the magnetic pad can be coated with a double-sided industrial adhesive, such as the adhesive referenced 467MP of the trademark 3M for example.In an illustrative, and non-limiting, example, the thickness of the magnetic pellet may be between one and three millimeters while its diameter may be between ten and twenty-five millimeters. The housing 20 may further be arranged, for example by sliding, in a half-shell 22. Such a half-shell 22 may be used for aesthetic aspects, by concealing the housing 20 on the instrument.

[0046] In the example of Figures 1 A and 1 B, the saxophone reinforcement spacer 410 is a spacer which is generally fixed to the saxophone by screwing, by means of screws arranged in holes provided in assembly tabs 412.

[0047] According to an alternative embodiment, illustrated in Figure 3, the original reinforcing spacer can be unscrewed from the saxophone and replaced by a fixing support 500 made so that it merges with the reinforcing spacer, and includes a ferromagnetic flat surface 520 in its center. In this case, the fixing support 500 is for example formed in a single block of mechanically resistant polymer material, so that the fixing support 500 merges with the spacer. The support is in this case made by injection, extrusion, or any other known method of shaping polymer parts. A ferromagnetic pellet, made of steel for example, is fixed by any known means on the flat surface 520 in the center of said support 500. Preferably, it is fixed by gluing.According to another embodiment variant, the fixing support 500 is made in a single monobloc piece in a ferromagnetic composite, by injection, extrusion or any other known method for shaping composite polymer parts. The ferromagnetic polymer comprises a polymer matrix in which ferromagnetic particles are dispersed. Whatever the variant, the polymer material constituting the monobloc fixing support 500 can be chosen from mechanically resistant polymers such as, for example, polyethylenes (PE), high density polyethylenes (HDPE), polyetheretherketones (PEEK), polymethyl methacrylates (PMMA) or polystyrenes (PS), this list being purely illustrative and not exhaustive. The fact of making the fixing support 500 in a block of polymer material, so that it merges with the spacer, makes it possible to gain in thickness.This embodiment also allows weight savings due to the lightness of the polymer material constituting the fixing support. In this case, the thickness of the fixing support 500, comprising the spacer and the ferromagnetic flat surface, can be between two and ten millimeters, preferably between three and five millimeters.

[0048] Figures 4A, 4B, and 4C respectively represent a perspective view of a portion of trumpet 100, equipped with a mounting bracket 200 of a transmitter housing arranged to comprise a tubular reinforcing spacer 110 of said trumpet, an exploded view and a sectional view of said mounting bracket 200. In these three figures, the same references are used to designate the same elements. The three figures are described simultaneously. The trumpet 100 comprises a bell 120 intended to increase and project the vibration emitted by the lips at the mouthpiece. Its more or less flared and more or less wide shape influences the sound qualities of the instrument. A reinforcing spacer 110, of tubular shape, makes it possible to stiffen the pipes of the instrument. Depending on the trumpet model, this spacer 1 10 can be placed between the bell pipe and the main slide connected to the mouthpiece, or between the main slide and another slide.The fixing support 200 makes it possible to grip the tubular spacer 1 10. For this, the fixing support 200 comprises a first part 210 and a second part 215 respectively provided with a groove 21 1 and 216, the shape of which is complementary to that of the spacer 1 10. The parts are positioned opposite each other and on either side of the tubular spacer 1 10, so that the tubular spacer 1 10 is housed in a channel formed by the two facing grooves 21 1 and 216. The two parts are then fixed to each other so that they grip the tubular spacer 1 10. The fixing can be carried out by any known means, such as gluing, screwing, riveting for example. Preferably it is made to facilitate the dismantling of the support, using screws 221 for example.For this, the two parts 210, 215 each comprise two threaded holes 212, 217, arranged on either side of the channel formed by the two facing grooves 211, 216, to accommodate two screws 221 and tighten the two parts 210, 215 against each other. Advantageously, the second part 215 has a hollow housing 219 intended to receive a third part 222, made of ferromagnetic material and whose flat surface is flush with the upper edge of the hollow housing 219 of said second part 215. This third part 222 is fixed in its housing 219 by any known means, such as gluing, screwing, riveting for example. Preferably, it is fixed in such a way as to facilitate its disassembly. For this purpose, a threaded hole 223 and 218 is provided respectively in the third part 222 and in the second part 215, in order to fix the two parts to each other by means of a screw 224.

[0049] Figure 5 shows a perspective view of a portion of trombone 300 equipped with a mounting bracket 200 of a transmitter box seen in exploded perspective. The reinforcing spacer 310 of a trombone, of tubular shape, is generally arranged between the bell pipe and the main slide. The mounting bracket is substantially identical to the mounting bracket equipping the trumpet of Figures 4A, 4B and 4C. The same references as in Figures 4B and 4C are therefore used to designate the same elements of the support. Only the grooves 21 1 and 216 respectively formed in the first part 210 and the second part 215 are of larger diameter to be able to accommodate the tubular spacer of the trombone, the diameter of which is larger than that of the spacer of a trumpet.

[0050] According to an alternative embodiment, it is possible to provide that the second part of the fixing support is identical regardless of the spacer. Thus, the second part of the fixing support could be identical to that referenced 430 in Figure 1 B and used for the fixing support of the saxophone. In this case, when the fixing support must accommodate a tubular spacer, the first fixing part is made in two parts, each of said two parts being provided with a groove to accommodate the tubular spacer when the two parts of said first part are joined. In this case, threaded holes can be provided on either side of the grooves of the two parts of the first part, in the second part and in the third part in order to assemble them by screwing for example.

[0051] Figure 6 shows a perspective view of a portion of a bugle 700. A bugle is a wind instrument that generally does not have a reinforcing spacer. According to another embodiment, a mounting bracket 600 for a transmitter box is specially made with an integrated reinforcing spacer to fit on the bugle. Such an embodiment of a mounting bracket can also fit on other instruments such as the bugle or the horn for example. Figure 7 shows this mounting bracket 600 in a top view and in section. The same references are used to designate the same elements in Figures 6 and 7 and these figures are described simultaneously to simplify the explanations.

[0052] The spacer integrated into the fixing support 600 comprises a first tab 610 and a second tab 620, intended to be positioned opposite one another. Each tab 610, 620 has curved ends 611, 621. The curved ends 611 of a first tab 610 are positioned opposite the curved ends 621 of a second tab 620, and on either side of two pipes, or slides, of the instrument in order to grip them. The two tabs 610 and 620 thus form the first part of the fixing support integrating the reinforcing spacer of the instrument and have at least one threaded orifice to allow them to be fixed to each other by screwing 650. Preferably, each tab 610, 620 of the spacer has, at right angles to the fixing support, a surface 612 whose shape is complementary to that of the fixing support.According to this embodiment, the surface of the second tab 620 of the spacer is surmounted by a second part 630 of the fixing support, said second part 630 comprising a hollow housing for housing therein a third ferromagnetic part 640, the surface of which is flat and flush with the upper edge of said hollow housing. The second part 630 may further have blind holes 631 on its periphery located under the hollow housing and shown in dotted lines in the top view of FIG. 7. These blind holes 631 make it possible to reduce the weight of the fixing support. The first tab 610 and the second tab 620 form the first part of the fixing support 600 integrating the reinforcing spacer of the bugle.The first tab 610, the second tab 620, the second part 630 of the fixing support and said third part 640 of the fixing support are advantageously pierced with at least one threaded hole to allow them to be fixed to each other by screwing 650.

[0053] According to another variant, as shown in Figure 9, the fixing support comprises a fourth part 630 integrating the reinforcing spacer of the wind instrument. This fourth part 630 has an elongated shape in two parts, formed by two rods 631, 632, arranged to cooperate with each other. More particularly, it comprises a first hollow rod 631 into which a second solid rod 632 is inserted. When the two rods are mounted one inside the other, their opposite ends each have curved edges forming a jaw 633, 634. The two end jaws 633, 634 of said fourth part 630 are arranged to grip two pipes or slides of the instrument. The two rods 631, 632 of this fourth part 630, forming a spacer for the instrument, also make it possible to adjust the length of the spacer, in order to adapt to the spacing between the two pipes or slides of the instrument.The first part 210 and the second part 215 of the fixing support are then arranged to grip this fourth part 630 forming a spacer. Said second part 215 comprises a hollow housing for housing the third ferromagnetic part 222, the shape of which is complementary to the raised element of the transmitter housing.

[0054] Just as for the saxophone, it is possible to provide another embodiment in which the fixing support for the flugelhorn is made in a single block with the spacer, made of polymer material for example. A piece with a flat and ferromagnetic surface can be fixed on this fixing support made of polymer material, also forming a spacer. According to another embodiment variant, ferromagnetic particles can be dispersed in the polymer material constituting the fixing support, so that the fixing support is merged with the spacer and with the flat ferromagnetic surface.

[0055] Whatever the embodiment, the ferromagnetic material constituting the third part 440, 222, 520, 640 is capable of becoming magnetized when a magnet approaches and can be chosen from iron, nickel, cobalt or an alloy based on one or more of these metals, such as steel. Preferably, this part is made of steel. Its thickness can be between one and six millimeters, preferably between two and four millimeters. This ferromagnetic flat surface allows the fixing, by magnetization, of the transmitter housing 20 provided, on one of its faces, with a magnetic pellet 25.

[0056] The fixing support 200, 400, 500, 600 with its ferromagnetic flat surface 222, 440, 520, 640 preferably has a shape complementary to the magnetic pad 25 fixed on one face of the transmitter housing. In the examples illustrated in Figures 1 to 7, this shape is circular. However, other geometric shapes can be envisaged without departing from the scope of the invention. Thus, in another example illustrated in Figure 8, which represents a fixing support 200 adapted for a trumpet or a trombone for example, the third ferromagnetic part 222 can have a flat 225 of substantially rectangular shape adapted to accommodate the magnetic pad fixed on one face of the transmitter housing. In this case, the magnetic pad is of square or rectangular shape and of width complementary to the flat 225.This embodiment makes it possible to fix the transmitter housing even more securely since it also makes it possible to prevent the latter from rotating around an axis perpendicular to the ferromagnetic surface under the effect of its weight. In this case, two orifices 226 are made in the ferromagnetic part, in line with the two orifices made in each of the first 210 and second 215 parts, so as to fix the three parts to each other by means of screws 224. Preferably, the diameter of said fixing support is between twenty and forty millimeters.It is also possible to provide at least one lug on the ferromagnetic part and / or on the magnetic pad and at least one recess opposite said lug on the magnetic pad and / or on the ferromagnetic part, so as to allow magnetic fixing of the transmitter housing with embedding of said at least one lug in said at least one recess in order to prevent any rotation of said transmitter housing around an axis perpendicular to the ferromagnetic surface, under the effect of its weight.

[0057] The bell 120, 720 of the wind instrument is flared and has an external edge 121, 721 as shown in FIG. 4A and in FIG. 6. Advantageously, whatever the wind instrument, the thickness of the fixing support 200, 400, 500, 600 comprising the reinforcing spacer 110, 310, 410, 500, 600, is dimensioned such that, when the fixing system is mounted on the wind instrument with the transmitter box 20 fixed by magnetization on said fixing support 200, 400, 500, 600, the total thickness of the fixing system constituted by said fixing support 200, 400, 500, 600 with said reinforcing spacer 110, 310, 410, 500, 600 and said transmitter box 20, does not protrude from a plane tangent to said external edge 121, 721 of the bell 120, 720 of the wind instrument. Thus, the transmitter box 20 is integral with the instrument and does not risk being snagged, or worse, torn off.The lightweight sound pickup microphone is attached by means of a clip to the bell 120, 720 of the instrument and connected by a cable to the heavier transmitter box 20, attached to the mounting bracket 200, 400, 520, 600 receiving the reinforcing spacer 110, 310, 410, 500, 600 located a few centimeters from the microphone. Consequently, the connecting cable has a length of a few centimeters to about ten centimeters and runs along the pipes of the instrument 100, 700, so that it no longer disturbs the musician and no longer risks getting caught or causing the microphone and / or the transmitter box to be torn off.

[0058] Preferably, the thickness of the fixing bracket 200, 400, 600, comprising the reinforcing spacer 110, 310, 410, 600, is between five and fifteen millimeters. When the fixing bracket 500, 600 is made with the spacer in a single monobloc piece, made of polymer, the thickness can even be reduced to between two and ten millimeters.

[0059] Preferably, the first 210, 420, 610, 620 and second parts 215, 430, 630 of the fixing support 200, 400, 600 are made of the same material as the wind instrument. Thus, in the example of the saxophone or brass instruments, the material is generally a brass alloy. However, other materials may be considered, such as polymers for example, which have the advantage of being lighter.The fixing system according to the invention, making it possible to fix on a wind instrument a high-frequency transmitter box connected by a cable to a microphone on board said wind instrument as described with regard to figures 1 to 8, comprises on the one hand the fixing support 200, 400, 500, 600, having a ferromagnetic flat surface 440, 222, 520, 640 and arranged to accommodate the reinforcing spacer 110, 310, 410, 500, 600 of the instrument and on the other hand, said transmitter box 20, one face of which is provided with a magnetic pad 25, so that said magnetic pad 25 allows fixing, by magnetization, of said transmitter box 20 on said ferromagnetic flat surface 440, 222, 520, 640 of said fixing support.However, the flat surface 222; 440; 520; 640 of the fixing support 200, 400, 500, 600 and the transmitter housing 20 can cooperate according to another type of reversible connection, for example a mechanical connection, so that the flat surface accommodates and holds said housing in place. The pad 25 fixed on one face of the transmitter housing 20 can take the form of any element capable of cooperating by reversible connection with the fixing support. Such an element will generally be fixed on one face of the transmitter housing 20 and is therefore in relief relative to this face. A reversible connection is defined as being a connection allowing the two parts to be separated without damaging them. Such a mechanical connection can for example be obtained with a fastening system using a self-gripping closure, for example.In this case, the raised element fixed to one face of the transmitter housing 20, by means of an adhesive for example, could for example be a first textile strip, for example equipped with closing hooks, while a second complementary textile strip, equipped with closing loops in the example, can be fixed by means of an adhesive on the flat surface of said fixing support. Thus, when the raised element of the housing is pressed against the flat surface of the fixing support, the hooks of the first textile strip hook onto the loops of the second textile strip and bind together, so that the housing can be held in position on the fixing support. The mechanical connection can also be obtained by cooperation of two fixing clips of complementary shapes.Such clips are for example made of a flexible material, capable of deforming to allow the two clips to be placed against each other, then of returning to its initial shape to maintain the connection between the two clips. Thus, at least one male fixing clip is for example provided on the periphery of the surface of the fixing support, while at least one fixing clip of complementary shape is provided on the periphery of the raised element of the housing. Whether by magnetization, by self-gripping mechanical connection or by mechanical clipping connection, the surface of the fixing support, the shape of which is complementary to that of the raised element arranged on the transmitter housing, is designed to accommodate and maintain, by a reversible connection, said raised element of said transmitter housing.

[0060] The invention finally relates to a wind instrument comprising a fixing system according to the invention. The invention applies to any type of wind instrument and more particularly to the saxophone, trombone, trumpet, horn, tuba, bugle, bugle.
