Specific embodiments

[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 rubber mouthpiece electric clarinet with a pressure sensor, as Figures 1-4 shown, includes a rubber mouthpiece 1; a biting and vibrating mechanism 2 is provided on the rubber mouthpiece 1. The biting and vibrating mechanism 2 includes an installation groove 201, and the installation groove 201 is opened at one end of the rubber mouthpiece 1. A driving block 202 is fixedly connected inside the installation groove 201. The driving block 202 is an arc-shaped structure. A pressure sensor 203 is connected inside the installation groove 201. The biting and vibrating mechanism 2 can detect the biting force of the user when using the electric clarinet body 4. The depth of the installation groove 201 is 3 / 4 of the length of the rubber mouthpiece 1. A positioning ring 204 is fixedly connected to the outside of the rubber mouthpiece 1. The structure of the installation groove 201 can facilitate the installation of the pressure sensor 203. The width of the installation groove 201 corresponds to that of the pressure sensor 203, so as to facilitate the installation of the pressure sensor 203. The structure of the driving block 202 can transmit the biting force received by the rubber mouthpiece 1 to the biting and vibrating part. The arc-shaped driving block 202 can facilitate the installation of the pressure sensor 203. When the pressure sensor 203 is installed, the end of the pressure sensor 203 can be movably installed along the arc-shaped driving block 202, avoiding the limitation of the installation of the pressure sensor 203 by the driving block 202. Embodiment

[0026] As Figures 1-4As shown in the figure, a drainage mechanism 3 is provided on the rubber mouthpiece 1. The drainage mechanism 3 includes an air duct 301 symmetrically opened on both sides inside the rubber mouthpiece 1. The end of the air duct 301 is connected to an exhaust pipe 302. The drainage mechanism 3 can discharge the saliva generated by the user's blowing during use, preventing the saliva from flowing into the air duct 301 and affecting the use of the rubber mouthpiece 1 and the sound production of the electric clarinet body 4. The structure of the air duct 301 can guide the gas, and the exhaust pipe 302 can connect the electric clarinet body 4 and the rubber mouthpiece 1. A positioning block 303 is fixedly connected to the outside of the exhaust pipe 302, and the positioning block 303 is connected to the middle of the outside of the exhaust pipe 302. The end of the exhaust pipe 302 is fixedly connected to an installation pipe 304. An air blowing groove 305 is opened at one end of the rubber mouthpiece 1 away from the installation groove 201. Both ends of the air blowing groove 305 are respectively communicated with the two air ducts 301. The air blowing groove 305 can guide the gas blown by the user, enabling the gas to flow into the air duct 301. A groove corresponding to the structure of the installation pipe 304 is opened inside the air duct 301, and the inside of the air duct is directly connected to the inside of the installation pipe 304. Therefore, the gas inside the air duct 301 can directly flow into the inside of the installation pipe 304, thus preventing saliva from flowing into the gap between the air duct 301 and the installation pipe 304. One end of the air blowing groove 305 is fixedly connected to a sealing block 306, and a drainage hole 307 is opened on the sealing block 306. Both ends of the drainage hole 307 are respectively communicated with the air blowing groove 305 and the air duct 301. The sealing block 306 and the drainage hole 307 structure can restrict the airflow at one end of the air blowing groove 305. By reducing the aperture of the gas flow, the gas flow rate is increased, and then the air pressure is reduced by increasing the gas flow rate, creating a gas pressure difference of air on both sides of the air blowing groove 305 and collecting the saliva in the air duct 301 on one side, improving the use effect of the rubber mouthpiece 1. The electric clarinet body 4 is connected to the rubber mouthpiece 1, and a positioning hole 5 is opened on the rubber mouthpiece 1.

[0027] When the rubber mouthpiece electric clarinet with a pressure sensor of the present utility model is in use, the user bites the rubber mouthpiece 1 with the mouth, and at the same time blows the gas in the oral cavity or lungs towards the rubber mouthpiece 1. The gas flows from both sides of the air blowing groove 305 into the air duct 301 after flowing to the air blowing groove 305. When the gas flows, it passes through the sealing block 306 and the drainage hole 307 on the side of the air blowing groove 305. Since the aperture of the drainage hole 307 is smaller than that of the air duct 301, the saliva blown out during the blowing process flows into the drainage hole 307 during the blowing process, facilitating the collection of saliva. During the biting process, the biting force deforms the rubber mouthpiece 1 made of rubber, thereby driving the driving block 202 inside the installation groove 201, causing the driving blocks 202 to approach each other and squeezing the pressure sensor 203 inside the installation groove 201. The pressure sensor 203 then converts the biting force into an electrical signal and transmits it to the electric clarinet body 4.
