Description

Title of the invention: SUPPORT FOR FIXING A HIGH FREQUENCY TRANSMITTER BOX ON A WIND INSTRUMENT

[0001] The present invention relates to a mounting bracket for a high-frequency transmitter box, said transmitter box being intended to be connected to a microphone mounted on a wind instrument.

[0002] When performing on stage, musicians traditionally use microphones to capture the sound of their instruments, so that they can then amplify them. For portable instruments, the microphones are generally mounted on the instrument, which gives the musician more freedom to move around the stage.

[0003] 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, conventionally 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 picked up 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 that will process them and send them to a mixing desk and / or a speaker intended to amplify them.

[0004] The cable connecting the microphone to the transmitter box is generally between one meter and one and a half meters long. The cable then dangles between the instrument and the musician's pocket or belt, which leads to the 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 his cable when playing his instrument.

[0005] 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 torn off.

[0006] Solutions have been considered to resolve this problem. For example, the company Samson Technologies markets a microphone referenced Airline AWXm comprising a transmitter box integrated into the microphone attachment clip at bell. Similarly, there are other microphones with an integrated transmitter on the mounting clamp, such as the one referenced N90 and marketed under the Xiaokoa trademark or the one referenced Saxmic-14R marketed under the Soundplus trademark. Another system referenced NUX B6 and marketed under the NUX trademark, consists of fixing the microphone on the transmitter box, which includes a flexible attachment, also called a clamp, which fits on the bell of the instrument.

[0007] These solutions are not, however, 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 which is not acceptable for musicians performing in front of an audience. In addition, the clip does not grip the bell sufficiently strongly and allows itself to rotate under the weight of the transmitter box, which results in 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 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.

[0008] Yet another method considered by many musicians is to fix the transmitter box to the body of the instrument by means of self-gripping and / or elastic straps and to fix the cable, connecting the microphone to the transmitter box, on the instrument with tape. However, this solution amounts to DIY which does not last over time and which also distorts the visual integrity of the instrument.

[0009] The invention therefore aims to remedy at least one of the drawbacks of the prior art. The invention aims in particular to design a device which allows the attachment of a high-frequency transmitter box, connected to a microphone on board the wind instrument, said device 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.

[0010] To this end, the invention relates to a mounting bracket for 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 mounting bracket being characterized in that it comprises a ferromagnetic flat surface designed to receive and hold by magnetization one face of said transmitter box, said face being provided with a magnetic pad, and in that it is arranged to comprise a reinforcing spacer for said wind instrument.

[0011] Thus, the mounting bracket, arranged to include a spacer for the wind instrument, makes it possible to hold the transmitter box securely on the wind instrument, so that the transmitter box is integral with the instrument and does not risk being torn off following an 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 disturbs the musician and no longer risks getting caught or being torn off. Finally, the transmitter box is integral with the instrument without distorting its visual integrity.

[0012] According to other optional features of the fixing bracket:

[0013] it comprises a first part and a second part, mutually arranged to grip the reinforcing spacer of the instrument, said second part having a hollow housing intended to receive a third ferromagnetic part forming said ferromagnetic flat surface, said first part, said second part and said third part being assembled to each other by screwing;

[0014] 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;

[0015] the reinforcing spacer of said instrument has an annular shape, said first part has a rim on which a first surface of said spacer ring rests and a central portion 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;

[0016] the reinforcing spacer of said instrument is formed of 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 said fixing support comprises a first part, formed by one of the two tabs of said spacer, surmounted by a second part having a hollow housing intended to receive a third ferromagnetic part forming said ferromagnetic flat surface, said first and second tabs, said second part and said third part being assembled to each other by screwing;

[0017] said first part and said second part are made of the same material as that of the wind instrument;

[0018] the fixing support is made in a single piece in a ferromagnetic polymer material;

[0019] the fixing support is made of a polymer material on which is fixed a ferromagnetic metal pellet;

[0020] the thickness of said fixing support is dimensioned such that when said transmitter box is fixed by magnetization on said fixing support, the total thickness of the assembly constituted by said fixing support with said spacer and said transmitter box, does not exceed a plane tangent to an external edge of a bell of said wind instrument.

[0021] The invention further relates to a system for fixing on a wind instrument, a high-frequency transmitter box connected by a cable to a microphone on board said wind instrument, said system being characterized in that it comprises on the one hand a fixing support as described above and on the other hand, a transmitter box one face of which is provided with a magnetic pad, so that said magnetic pad allows fixing, by magnetization, of said transmitter box on said ferromagnetic flat surface of said fixing support.

[0022] The invention finally relates to a wind instrument comprising a fixing support as described above or the fixing system as described above.

[0023] 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:

[0034] [Fig.8], an exploded view of a fixing bracket according to another embodiment.

[0035] 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.

[0036] The term "reinforcing spacer" of a wind instrument is defined as a part making it possible 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 the mouthpiece.

[0037] According to the invention, the mounting support of the transmitter box is arranged to comprise a spacer for reinforcing the wind instrument.

[0038] [Fig.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.

[0039] [Fig.lB] shows an exploded view of a mounting bracket 400 of a transmitter box intended to be connected by cable to a microphone on board such a saxophone and comprising the reinforcing spacer 410 for saxophone. The reinforcing spacer 410 of saxophone 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.

[0040] 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 so 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.

[0041] 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.

[0042] 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 may be provided with blind holes 433 on its periphery, as shown in [Fig.lB], in its lower part located under the hollow housing 431. These holes 433 are regularly spaced along the periphery of the part. Such holes 433, optional, are advantageously provided to lighten the weight of the part.

[0043] 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.

[0044] [Fig. 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.

[0045] In the example of Figures 1A and 1B, the reinforcing spacer 410 for the saxophone is a spacer which is generally fixed to the saxophone by screwing, by means of screws arranged in holes provided in assembly tabs 412.

[0046] According to an alternative embodiment, illustrated in [Fig. 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 comprises 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 alternative embodiment, the fixing support 500 is made in a single piece in a ferromagnetic composite magnetic, 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 single-piece fixing support 500 may 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 producing the fixing support 500 in a block of polymer material, so that it merges with the spacer, allows for a gain in thickness. This embodiment also allows for a gain in weight 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, may be between two and ten millimeters, preferably between three and five millimeters.

[0047] 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 110 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 110. For this, the fixing support 200 comprises a first part 210 and a second part 215 respectively provided with a groove 211 and 216, the shape of which is complementary to that of the spacer 110. The parts are positioned opposite each other and on either side of the tubular spacer 110, so that the tubular spacer 110 is housed in a channel formed by the two facing grooves 211 and 216. The two parts are then fixed to each other so that they grip the tubular spacer 110. The fixing can be carried out by any known means, such as gluing, screwing, riveting for example. Preferably, it is carried out to facilitate the disassembly of the support, by means of 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, 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.

[0048] [Fig. 5] represents a perspective view of a portion of trombone 300 equipped with a fixing support 200 of a transmitter box seen in exploded perspective. The reinforcing spacer 310 of a trombone, of tubular shape, is generally arranged between the pipe of the bell and the main slide. The fixing support is substantially identical to the fixing support 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 211 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.

[0049] [Fig. 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 of 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. [Fig. 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.

[0050] 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 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 also constitutes the first part of the fixing support. A second part 630 of the fixing support, arranged on the surface of the second tab 620, comprises 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 of the spacer, the second tab 620 of the spacer forming the first part of the fixing support 600, 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.

[0051] Just as for the saxophone, it is possible to provide another embodiment according to which the fixing support for the bugle 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 variant embodiment, 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.

[0052] Whatever the embodiment, the ferromagnetic material constituting the third part 410, 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.

[0053] 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 [Fig. 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 square or rectangular in shape and has a width complementary to the flat 225. This embodiment makes it possible to fix the transmitter box even more securely since it allows furthermore to prevent the rotation of the latter, 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, at the right angle to 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.

[0054] 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 transmitter box 20 is fixed by magnetization on said fixing support 200, 400, 500, 600, the total thickness of the assembly 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 exceed a plane tangent to said external edge 121, 721 of the bell 120, 720 of the wind instrument. Thus, the transmitter box 20 is integrated with the instrument and does not risk being caught, 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.

[0055] Preferably, the thickness of the fixing support 200, 400, 600, comprising the reinforcing spacer 110, 310, 410, 600, is between five and fifteen millimeters. When the fixing support 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.

[0056] 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 The material is generally a brass alloy. However, other materials can be considered, such as polymers for example, which have the advantage of being lighter.

[0057] The invention also relates to a system for fixing a high-frequency transmitter box connected by a cable to a microphone mounted on said wind instrument to a wind instrument. This system comprises, on the one hand, the fixing support 200, 400, 500, 600 according to the invention, having a ferromagnetic flat surface 410, 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 410, 222, 520, 640 of said fixing support.

[0058] The invention finally relates to a wind instrument comprising a fixing support 200, 400, 500, 600 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.
