[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0025] A detachable inner biting vibrato plate in an electric wind instrument, as Figures 1 - 5As shown in the figure, it includes a circuit board 1; a detection mechanism 2 is provided on the circuit board 1. The detection mechanism 2 includes a first pressure plate 201 and a second pressure plate 202. The first pressure plate 201 and the second pressure plate 202 are symmetrically connected to the top and bottom ends of the circuit board 1. A contact induction head 203 is fixedly connected to the inner side of the first pressure plate 201. A travel switch 204 is fixedly connected to the circuit board 1. The detection mechanism 2 can detect the biting force received by the biting vibration plate, and thus convert the biting force into an electrical signal for output. The travel switch 204 can convert the extrusion force into different electrical signals according to the magnitude of the different degrees of extrusion force received. The contact induction head 203 is made of silicone material. A fixing seat 205 is fixedly connected between the contact induction head 203 and the first pressure plate 201. The fixing seat 205 is of a circular structure, and the contact induction head 203 is of an arc structure. The silicone material contact induction head 203 can reduce the loss caused to the travel switch 204. At the same time, the silicone material can buffer the extrusion force through its own deformation. At the same time, the arc-shaped contact induction head 203 can maintain the contact angle with the travel switch 204 at different angles. The first pressure plate 201 and the second pressure plate 202 are made of elastic materials. Installation holes 206 with corresponding structures are provided at one end of the first pressure plate 201 and the second pressure plate 202. The first pressure plate 201 made of elastic material can approach each other when receiving pressure and transfer the pressure to the travel switch 204. At the same time, it can rebound to the initial state when the pressure is lost. Compared with the traditional biting vibration plate, the distance between the ends of the first pressure plate 201 and the second pressure plate 202 is farther, thereby improving the sensitivity and detection range of pressure detection. The travel switch 204 is electrically connected to the circuit board 1. The electrically connected travel switch 204 can transmit the converted electrical signal into the circuit board 1, and convert the electrical signal into a control signal through the circuit board 1 for transmission. Embodiment

[0026] Such as Figures 1 - 5As shown in the figure, an installation mechanism 3 is provided on the circuit board 1. The installation mechanism 3 includes a fastening bolt 301, which is movably connected to the circuit board 1 and passes through the installation hole 206. The installation mechanism 3 can conveniently install the first pressure plate 201 and the second pressure plate 202 on the circuit board 1, thus improving subsequent installation and use. At the same time, the biting vibration plate is a plug-and-play structure, which can be conveniently disassembled from or installed into the rubber nozzle, thus improving the installation convenience of the biting vibration plate. The end of the fastening bolt 301 is meshed with a fastening nut 302. A washer 303 is connected between the fastening nut 302 and the circuit board 1. The washer 303 is sleeved outside the fastening bolt 301. The structure of the fastening bolt 301 and the fastening nut 302 can install the first pressure plate 201 and the second pressure plate 202 on the circuit board 1. At the same time, the structure of the washer 303 can space the first pressure plate 201 from the circuit board 1, thereby controlling the stroke of the biting vibration plate. By installing different washers 303, the distance between the first pressure plate 201 and the circuit board 1 can be conveniently controlled, and then the distance between the first pressure plate 201 and the contact sensor 203 and the travel switch 204 can be conveniently controlled. A mounting seat 304 is fixedly connected to the top of the circuit board 1. A connecting wire 305 is connected inside the mounting seat 304, and the connecting wire 305 is fixedly connected to the circuit board 1.

[0027] When the detachable inner biting vibration plate of the present utility model is in use, the biting vibration plate receives the biting force transmitted by the rubber nozzle. The first pressure plate 201 and the second pressure plate 202 are deformed accordingly. The ends of the first pressure plate 201 and the second pressure plate 202 approach each other. The contact sensor 203 on the first pressure plate 201 contacts the travel switch 204 and continuously presses the travel switch 204. The travel switch 204 then converts the received pressing force into an electrical signal and outputs it to the circuit board 1. The circuit board 1 converts the electrical signal into a control signal and transmits it. When the squeezing force generated by the biting of the biting vibration plate is lost, the first pressure plate 201 and the second pressure plate 202 made of elastic material rebound and recover under the action of their own elasticity, and the ends of the first pressure plate 201 and the second pressure plate 202 move away from each other.

[0028] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
