    description
    Technical Field The invention relates to a method for manufacturing a mouthpiece of a wind instrument and such a mouthpiece.
    Background Art Mouthpieces for brass instruments are very important for playing the instrument. The mouthpiece has a kettle into which the air is introduced into the wind instrument and an edge around the kettle which rests on the lips of the player or wind player. Depending on your wishes and habits, the player can find different bowl depths, bowl diameters and edge widths on the market. As a rule, however, the edge is flat and can lead to pressure points and, depending on the shape of the mouth, even air escape. This can adversely affect sound, flexibility, range, control and endurance.
    [0003] WO 08 141 450, for example, proposes an edge shape that provides recesses for the lower and upper lip. However, this shape has the disadvantage that it is often perceived as unpleasant and annoying if the recesses do not fit exactly.
    SUMMARY OF THE INVENTION It is an object of the invention to produce a mouthpiece that solves the problems of the prior art described above.
    This object is achieved with the method according to claim 1. By detecting the three-dimensional shape of the mouth part of the player, an individual adaptation of a mouthpiece to the mouth part shape of the player can be achieved. This means that the mouthpiece fits exactly on the lips and mouth area of the player and pressure points or even the escape of air is minimized. This makes playing less stressful for the player and improves the sound quality, range, control, endurance and flexibility of the wind player.
    [0006] Further advantageous embodiments are specified in the dependent claims.

    WAYS OF CARRYING OUT THE INVENTION An exemplary embodiment of a method for producing a mouthpiece for a wind instrument is described below.
    [0009] The wind instrument is preferably a brass instrument.
    Fig. 5 shows an example of a manufactured mouthpiece 10. Preferably, the mouthpiece 10 is a bowl or funnel mouthpiece. The mouthpiece 10 is preferably removable from the wind instrument. The mouthpiece 10 preferably has a mouthpiece shaft 11 which is designed for connection to the wind instrument. The mouthpiece shaft 11 has, for example, a conical shaft (for example cone ratio KV 1:20) with which the mouthpiece can be inserted into the mouth tube of the wind instrument. The mouthpiece shaft 11 tapers towards the distal end of the mouthpiece shaft 11, i.e. in the direction of the wind instrument and / or in the direction away from the area of the mouthpiece 10 which abuts the mouth part. The mouthpiece 10 preferably has an area which lies against the mouth part. The area adjacent to the mouth part and / or the mouthpiece 10 has a bowl or funnel which is delimited by an edge. The rim is designed to rest on the mouth part of the player to play the wind instrument. The area adjacent to the mouth part and / or the kettle or funnel is connected to the mouthpiece shaft 11 and / or the mouth pipe of the wind instrument via a back hole. The bore is preferably arranged coaxially with the mouthpiece shaft 11, the mouth pipe and / or the kettle or funnel. The back hole preferably runs along a straight axis. The shape of the mouthpiece described is general
    CH 714 915 A2 known. The following describes the manufacture of the mouthpiece with an edge that is adapted to the mouth part of a player.
    In a first step, the three-dimensional (3D) shape of the mouth part of the player is recorded. The mouth part comprises at least part of the lips, preferably the entire upper and lower lip of the player and / or at least a part of the area surrounding the lips. The three-dimensional shape of the mouth part can be recorded using a 3D scanner, preferably a contactless 3D scanner. However, it is also possible to calculate the three-dimensional shape from a series of images of the mouth area, for example from several images or a video sequence. The 3D scanner can, for example, be a time-of-flight scanner or a triangulation scanner. High-quality 3D scanners are preferably used here. However, it is also possible to use the 3D scanners used in mobile phones to capture the 3D shape of the player's mouth.
    Preferably, the step of detecting the three-dimensional shape of the mouth part of the player comprises detecting the three-dimensional shape of the mouth part of the player in a first state and detecting the mouth part in a second state.
    In the first state, the three-dimensional shape of the mouth part is detected without a mouthpiece placed on the lips or any other object covering the lips or the mouth part. The player preferably brings the mouth part into a position in which the player would play the wind instrument during the acquisition of the 3D shape of the mouth part in the first state. Since no object such as the wind instrument or a mouthpiece covers the mouthpiece to be captured while the 3D shape of the mouthpiece is being captured, the shape of the mouthpiece resting on a recorded mouthpiece can be captured. The term grasping mouthpiece is used herein to refer to a mouthpiece used to grasp the three-dimensional shape of the mouth part and to differentiate it from the mouthpiece 10 to be manufactured. The player preferably brings the lips into a tense position in the first state during the acquisition of the 3D shape of the mouth part. The tense lip position is preferably achieved by playing a note in the high register, or simulating playing a note in the high register.
    In the second state, the mouth part is detected with a detection mouthpiece 2 (see Fig. 2). The detection mouthpiece 2 is preferably a mouthpiece commonly used by the player. However, any mouthpiece can be selected as an acquisition mouthpiece. In the second state, the detection mouthpiece 2 is placed on the mouth part of the player. In the second state, the mouth part and the detection mouthpiece 2 are brought into a position in which the player prefers to play the detection mouthpiece. Preferably, the player plays in the second state, i.e. with the acquisition mouthpiece, the wind instrument connected to the acquisition mouthpiece. The detection of the mouth part with the detection mouthpiece 2 or with the wind instrument allows the usual playing position of the detection mouthpiece 2 on the mouth part of the player to be determined. Preferably the mouth part is in the second state, i.e. with the detection mouthpiece 2, also recorded three-dimensionally. However, the mouth part could be in the second state, i.e. with the acquisition mouthpiece 2, also (only) record two-dimensionally, i.e. with one or more pictures (e.g. photos). This is sufficient to determine the approximate position of the registration mouthpiece on the mouth part of the player. However, the position of the detection mouthpiece 2 can be better determined with a three-dimensional detection.
    In a second step, the mouthpiece 10 is manufactured on the basis of the detected 3D shape of the mouth part of the player, in particular on the basis of the detected mouth part of the player in the first and second state. Preferably, the 3D shape of the mouthpiece 10 is determined on the basis of the three-dimensional shape of the mouth part of the player, in particular on the basis of the detected mouth part of the player in the first and second states, and the mouthpiece 10 on the basis of the determined three-dimensional shape of the mouthpiece 10 manufactured. The 3D shape of the mouthpiece 10 is such that the area adjacent to the mouth part, in particular the edge of the kettle or funnel, has a shape that at least partially corresponds to the three-dimensional shape of the mouth part of the player. The 3D shape of the mouthpiece 10 is such that the area adjacent to the mouth part, in particular the rim of the kettle or funnel, has a shape that at least partially corresponds to the three-dimensional shape of the area of the mouth area of the player in the second state on the detection mouthpiece The step of determining the 3D shape of the mouthpiece 10 preferably has a step of adapting the 3D shape of the mouth part of the player and / or the 3D shape of the mouthpiece 10. This step can be done automatically or by a user. 3 shows an example of an adaptation of the captured 3D shape of the mouth part of the player for the determination of the 3D shape of the mouthpiece 10. In particular the 3D shape of the mouth part of the player and / or the 3D shape of the mouthpiece 10 in the area 1 of the gap between the The player's lips are adjusted. Without this step, this area 10 would lead to a sharp edge which is uncomfortable when playing. Rounding off this area 10 allows a 3D shape of the mouthpiece 10 to be produced which is very pleasant to play. However, it is also possible to carry out this step on the 3D shape of the mouthpiece 10. The 3D shape of the mouthpiece 10 includes in particular the edge 14 of the bowl 12 or funnel (see for example FIG. 4). However, it is also possible that the 3D shape of the mouthpiece 10 also depicts the shape of the bowl 12 or funnel, the mouthpiece shaft 11 and / or the bore. The 3D shape of the mouthpiece 10 is preferably further produced on the basis of parameters of the mouthpiece 10 which are communicated by the player of the wind instrument for the production of the mouthpiece 10. These parameters preferably have the edge diameter on the inside, edge diameter on the outside and / or the edge width of the boiler 12 or funnel, preferably at least two of these parameters. The edge preferably corresponds
    CH 714 915 A2 diameter inside, edge diameter outside and / or the edge width of the bowl 12 or funnel the parameters of the detection mouthpiece 2. However, it is also possible that individual parameters of the detection mouthpiece 2 are changed or a completely new mouthpiece is made according to customer requirements. These parameters preferably also have the parameters for the back hole, the bowl or funnel shape and / or the mouthpiece shaft 11.
    Fig. 4 shows an embodiment for the 3D shape of the mouthpiece, in particular the edge 14. The specific 3D shape of the mouthpiece 10 preferably has two elevations 14.1, an area for the lower lip 14.2 and an area for the upper lip 14.3. The two elevations 14.1 are designed to lie between the lips of the player. The area for the lower lip 14.2 is designed to rest on the lower lip (and possibly the area of the mouth area below the lower lip). The area for the upper lip 14.3 is designed to rest on the upper lip (and possibly the area of the mouth area above the upper lip). The two elevations 14.1, the area for the lower lip 14.2 and the area for the upper lip 14.3 together form a closed ring which forms the edge of the kettle or funnel and includes the opening of the kettle or funnel. The area for the lower lip 14.2 and the area for the upper lip 14.3 are separated from one another by the two elevations 14.1. The form described in FIG. 4 is the normal case. However, other 3D shapes of the mouthpiece 10 can occur for individual players and / or mouth parts.
    [0017] A trial mouthpiece is preferably produced on the basis of the 3D shape of the mouth part or the mouthpiece 10. The player can therefore try out the sample mouthpiece a few days before the final mouthpiece is ordered. The sample mouthpiece is preferably produced using an additive manufacturing method, in particular using a 3D printer. The sample mouthpiece is preferably produced from a plastic. If the 3D shape of the sample mouthpiece does not fit the player, the 3D shape of the mouthpiece 10 can be adapted on the basis of the player's feedback and / or a new detection of the mouth part of the player. If necessary, the step of making the sample mouthpiece can be repeated until the 3D shape of the sample mouthpiece fits the player. Once the player agrees to the 3D shape of the sample mouthpiece, the final mouthpiece 10 can be made based on the particular 3D shape of the mouthpiece 10.
    Preferably, the mouthpiece 10 is made of a metal, e.g. Made of brass. The fully formed metal mouthpiece 10 is preferably coated with another metal, e.g. galvanized. The other metal is, for example, silver, gold or titanium. However, it is also possible to make the mouthpiece 10 from other materials such as plastic, e.g. Manufacture polycarbonate (Lexan).
    There are various manufacturing methods for the manufacture of the (final) mouthpiece 10.
    In a first embodiment, machining is selected. The final mouthpiece is cut or milled out of a metal rod or block, for example. In this case, the milling machine or the cutting tool is given the 3D shape of the mouthpiece 10 (including bowl or funnel shape, shape of the mouthpiece shaft) as an input file and then mills or machines the mouthpiece from a metal block, e.g. a metal rod. It is also possible to use different cutting techniques. Thus, the outer shape of the mouthpiece 10 and the shape of the bowl or funnel can be milled while the back hole is being drilled.
    In a second embodiment, machining is also selected. However, not the entire mouthpiece, but only the shape of the rim 14 of the bowl or the funnel is machined from an existing mouthpiece 10 on the basis of the 3D shape of the mouthpiece 10. The existing mouthpiece 10 can be selected, for example, on the basis of the parameters of the mouthpiece 10 received from the user (parameters for bowl or funnel shape, edge width, edge diameter inside and / or outside, mouthpiece shaft shape and / or back hole shape). For example, an existing mouthpiece 10 can be used as a blank, with a cutting tool, preferably a milling machine, cutting out / milling out the shape of the mouthpiece edge on the basis of the 3D shape of the mouthpiece 10. In this case, the milling machine receives the 3D shape of the mouthpiece edge 14 as an input file and then mills the mouthpiece edge in accordance with the determined 3D shape of the mouthpiece 10 or the mouthpiece edge 14 from the existing mouthpiece 10.
    In a third embodiment, it is also possible to use an additive manufacturing method for the manufacture of the mouthpiece 10. In one embodiment, a 3D printer, preferably a metal-processing 3D printer, could be used as an additive manufacturing method. It would also be possible to manufacture the mouthpiece by laser synthering or by a casting process, in particular a metal casting process. A particularly advantageous (metal) casting method for producing the mouthpiece 10 is the precision casting.
    Preferably, the mouthpiece 10 made of metal is coated with another metal, e.g. with silver, gold or titanium.
