Description

Technical Field

[0001] The utility model relates to the technical field of electric blowpipes, in particular to a controlled blow nozzle for an electric blowpipe. Background Art

[0002] The electric blowgun is also known as the "electric saxophone" or "electronic wind instrument". Its principle is to use airflow to control electric current, and then convert the current signal into a sound signal to make music. When playing the electric blowgun, it is necessary to blow air into the mouthpiece to play.

[0003] According to Chinese patent publication number CN218585625U, the patent provides a mouthpiece for an electric blowpipe with quick detachability and precise vibrato control, including a soft rubber mouthpiece, a mouthpiece bracket is provided at one end of the soft rubber mouthpiece, a blowing air pressure signal connecting tube, a vibrato air pressure signal connecting tube and an exhaust and drainage pipe are respectively fixed to the end of the mouthpiece bracket away from the soft rubber mouthpiece, a blowing air pressure connecting column is fixed to the end of the blowing air pressure signal connecting tube close to the soft rubber mouthpiece, and the structural design of the cavity assembly makes it convenient to perform interference fit connection with the blowing air pressure connecting column, the exhaust connecting column and the bite vibrato air pressure connecting column, thereby ensuring the overall air tightness, and the overall structural matching design makes it convenient to generate blowing signals and vibrato control signals when blowing into the air inlet of the mouthpiece or biting the soft rubber mouthpiece, thereby accurately realizing the richness and diversity of vibrato control, and the excess airflow and water vapor are conveniently discharged to the outside through the exhaust connection cavity, the exhaust connecting column and the exhaust drainage pipe.

[0004] In the above patent, the air pressure change in the closed cavity is used to control the air pressure sensor to achieve the control of the vibrato. However, in actual use, the closed cavity will expand and age due to the influence of air pressure for a long time, resulting in air leakage, which will cause unstable air pressure and reduce the control accuracy. On the other hand, the amount of air blown by the human body is related to its own lung capacity. When playing for a long time, the amount of air blown will be reduced due to fatigue, further causing the problem of unstable air pressure, thereby affecting the performance effect. In view of this, we propose a control mouthpiece for an electric blowpipe. Utility Model Content

The method can improve the splicing stability between the bite tremor circuit board 31 and the mouthpiece pressure piece 21, and is also convenient for later replacement and disassembly. The end of the bite tremor circuit board 31 away from the card slot 32 is connected to the piezoelectric film 33, and the piezoelectric film 33 is installed with a pressure sensor 34. The end of the bite tremor circuit board 31 away from the piezoelectric film 33 is installed with a power connection block 35.

[0028] In this embodiment, the first mouthpiece 71 is manually bitten to drive the mouthpiece pressure plate 21 to elastically deform, and the pressure sensor 34 is pressed by the pressure head 24 to contact the pressure sensor 34, and then the bite force is used to control the pressure change to achieve precise control of the vibrato of the electric blowpipe. Example

[0029] See also Figure 1-7On the basis of the first embodiment, the utility model provides a technical solution: preferably, an air pressure connecting pipe 4 is provided on the connecting seat 1, an air tube cavity 6 is opened on the connecting seat 1, each air pressure connecting pipe 4 is respectively plugged into the corresponding air tube cavity 6, an installation cavity 5 is opened on the connecting seat 1, a mouthpiece pressing piece 21 and a bite vibration circuit board 31 are both plugged into the installation cavity 5, a mouthpiece mechanism 7 is provided on the connecting seat 1, and the mouthpiece mechanism 7 includes a first mouthpiece 71. The first mouthpiece 71 is made of soft rubber material and has an arc-shaped structure, which is convenient for the performer to bite and play without generating a strange feeling, and the arc surface has a small friction, which is convenient for performers with a small mouth shape. When used by a player, the first mouthpiece 71 is fixedly connected to the side of the connecting seat 1 away from the tracheal cavity 6, and a first air hole 72 is provided at the end of the first mouthpiece 71 away from the connecting seat 1, and the first air hole 72 is connected to each tracheal cavity 6. The mounting cavity 5 is also provided on the first mouthpiece 71, and the mounting cavity 5 on the connecting seat 1 is connected to the mounting cavity 5 on the first mouthpiece 71. The end where the pressure head 24 on the mouthpiece pressing plate 21 is located extends into the mounting cavity 5 of the first mouthpiece 71, and the mouthpiece pressing plate 21 directly extends to the inside of the first mouthpiece 71, which can facilitate the player to quickly bite into the position where the pressure sensor 34 is located.

[0030] In this embodiment, the mouthpiece pressure plate 21 and the bite and vibration circuit board 31 are spliced ​​together by clamping the clamping block 22 on the clamping slot 32. The mouthpiece pressure plate 21 and the bite and vibration circuit board 31 are installed in the installation cavity 5 in a plug-in manner. The air pressure connecting pipe 4 has a corresponding air pipe cavity 6 on the connecting seat 1. The wires of the electric blowpipe can be directly electrically connected to the power connection block 35. The pressure mechanism 2 and the control mechanism 3 are spliced ​​in a split type, which can be easily disassembled and replaced, and is also convenient for maintenance. Example

[0031] See also Figure 1-7 On the basis of the second embodiment, the utility model provides a technical solution: preferably, in order to facilitate the bite habits and playing habits of different players, the mouthpiece mechanism 2 8 includes a second mouthpiece 81, the second mouthpiece 81 is made of soft rubber material, and is a square structure that can be directly replaced with the first mouthpiece 71 on the connecting seat 1. The edge of the second mouthpiece 81 adopts an arc chamfer, which increases the mouthpiece area, is convenient for players with larger mouth shapes, and improves the bite stability. The second mouthpiece 81 is connected to the side of the connecting seat 1 away from the tracheal cavity 6, and a second air hole 82 is provided at one end of the second mouthpiece 81 away from the connecting seat 1, and the second air hole 82 is connected to the tracheal cavity 6. The mounting cavity 5 is also provided on the second mouthpiece 81, and the mounting cavity 5 on the connecting seat 1 is connected to the mounting cavity 5 on the second mouthpiece 81.

[0032] In this embodiment, the second mouthpiece 81 can adopt a square structure instead of the arc structure of the first mouthpiece 71. Mouthpieces with different structures can better adapt to the biting habits of different performers, thereby improving the flexibility of the mouthpiece and the adaptability of the performers. At the same time, the pressure head 24 of this case can also adopt 3mm square silicone sheets, plastic sheets and other elastic materials. When using the second mouthpiece 81, the square pressure head 24 can better adapt to the pressure direction generated by the biting deformation of the second mouthpiece 81, thereby improving the accuracy of pressure sensing.

[0033] Working principle: the mouthpiece pressing piece 21 is stuck on the card slot 32 of the bite and tremble circuit board 31 through the card block 22, so that the mouthpiece pressing piece 21 and the bite and tremble circuit board 31 are spliced ​​together. At the same time, the empty part between the mouthpiece pressing piece 21 and the bite and tremble circuit board 31 is fitted through the pad block 23 to ensure the stability of the splicing. The support of the pad block 23 can make one end of the pressure head 24 on the mouthpiece pressing piece 21 suspended in the air and facilitate elastic deformation. The pressure head 24 contacts the pressure sensor 34 to control the bite and tremble circuit board 31 through pressure, thereby realizing the tremolo control of the electric blowpipe. The spliced ​​mouthpiece pressing piece 21 and the bite and tremble circuit board 31 are inserted into the installation cavity 5 at the same time, and the pressure head 24 and the pressure sensor 34 are extended to the installation cavity 5 of the first mouthpiece 71. The first mouthpiece 71 is manually bitten to drive the mouthpiece pressing piece 21 to elastically deform, and through the pressure head 24 The pressure sensor 34 is squeezed into contact, and then the bite force is used to control the change of pressure to achieve precise control of the vibrato of the electric blowpipe. By blowing air in the first air hole 72, the air pressure enters the electric blowpipe through the air pressure connecting tube 4, thereby realizing the sound control of the electric blowpipe. The power block 35 is connected to the wires in the electric blowpipe, so that the bite and vibrato circuit board 31 can realize synchronous vibrato sound in real time through the electrical signal of the pressure sensor 34. Compared with the prior art, this case uses the bite force to control the pressure to accurately control the change of the vibrato of the electric blowpipe, and will not cause the problem of unstable vibrato due to unstable air pressure. At the same time, it avoids controlling the vibrato according to the player's lung capacity for a long time, which saves the player's physical strength. In addition, using the teeth to bite the first mouthpiece 71 can more conveniently control the size of the pressure, which is more conducive to operation and reduces the error rate of performance.

[0034] On the other hand, the pressure mechanism 2 and the control mechanism 3 in this case are connected in a split manner, which can be easily disassembled and replaced, and is also convenient for maintenance. The sensors involved in this case can adopt the series sensors produced by Shenzhen Ruisite Sensing Instrument Co., Ltd., and the supporting circuits and power supplies are also provided by the manufacturer; in addition, the circuits, electronic components and modules involved in this case are all existing technologies, which can be fully implemented by those skilled in the art without further elaboration.
