Induction structure of electronic drum

This creation is an inductive structure of an electronic drum, especially one that eliminates the drumhead noise of an electronic drum to simply convey the electronic induction sound.

Conventional electronic sensing percussion instruments, such as electronic drums, place the sensor in the center of the back of the striking surface to capture the striking force and sense it into the computer's memory. After selecting the memory to store the sound, the sound is finally The horn emits the sound of the blow; however, the face is the drumhead. Usually, the plastic disk surface will cause the double sound source due to the sound of its own body, resulting in noise. If the rubber disk is used, it will be self-made. The sound is reduced, but the noise of the dual source is still not eliminated; therefore, there is still a need for further improvement.

The sensing structure of the electronic drum of the present invention is to find and separately test other possible methods for eliminating noise, in order to achieve the purpose of purifying the electronic induction sound, and finally to have the structure generator of the creation.

For example, the sensing structure of the electronic drum of the present invention is considered in view of the above various situations, except that the drum surface is excluded from the vibrating sound of hammering and rebounding, and the drum surface is absorbed by the breathable drum surface, and the durability and humidity resistance are considered. And the degree of elasticity, especially selected from the mesh surface woven with resin fiber.

For example, the sensing structure of the electronic drum is considered to be located not far from the center, and the center is more susceptible to external forces to fluctuate in the distance. When the fluctuation from the center is transmitted to the induction ring adhered to the back of the outer edge, the induction ring can be sensitively touched by the accumulated force at the same time, so that the tapping signal emits a full-sensing sound.

The creation system is an inductive structure of an electronic drum, which is mainly formed by a combination of an induction ring and a woven mesh. The induction ring is a ring-shaped foam body, and a sensing piece is interposed inside and an inductive signal line is connected.

For example, the induction structure of the electronic drum is mainly formed by a combination of an induction ring and a woven mesh, wherein the woven mesh is formed by weaving of resin fibers, and an induction ring is adhered to the inner diameter of the periphery of the back surface.

Please refer to the first figure for a schematic diagram of a conventional electronic drum cutting surface, in which the electronic drum 10 is applied as an example, and the sensor 11 is placed at a central point below the drumhead 12, supported by the inner drum frame 13, and the drumhead 12 is The metal round frame 14 is fixed on the outer drum frame 15. When the drum surface 12 is hammered by the drum rod 16 due to the solid surface, the drum surface 12 itself will sound independently, and the sound is also sensed. The device 11 is then transmitted to the computer via the signal line 17, and finally the sound of the electronic sensor is emitted by the sound horn, but the drum sound and the electronic sound are caused to cause noise, which is a lack of existing and extremely improved.

Please refer to the second figure, which is a schematic diagram of the structure of the electronic drum cutting surface. The inductive structure of the electronic drum 20 of the present invention is formed by combining the induction ring 21 and the woven mesh 22, wherein the induction ring 21 is in the form of a ring-shaped foam, and a sensing piece 23 is interposed therein, and the sensing signal line 24 is connected. The woven mesh 22 is formed by weaving of resin fibers, and an induction ring 21 is adhered to the inner diameter of the periphery of the back surface.

Continuation, please refer to the second figure, in which the woven mesh 22 of the present invention is fastened to the electronic drum frame 26 by the metal top frame 25, except that the vibration sound of the hammer can be absorbed to avoid noise generation, and consideration is given. Its durability, moisture resistance and elasticity are woven into a mesh surface made of resin fibers.

Still referring to the second figure, the artificial sensing ring 21 is disposed at the inner diameter of the outer edge of the back surface of the woven mesh 22 by the adhesive layer 27, because the sensing ring 21 is an annular foam, and the sensing piece 23 is sandwiched. In the meantime, the vibration of the entire annular foam can be completely felt, so that when the tapping point of the woven net 22 falls at the center, it is easy to collect the wave-like power to clearly convey the adhesion to the back of the outer edge. The induction ring 21 emits a sharp and full-sensing sound.

Referring to the second figure, the embodiment of the electronic drum 20 of the present invention shows that under the induction ring 21 in the interior of the electronic drum frame 26, a layer of annular foam 28 is also lined, but there is no sensing piece 23 in the inner portion. And supported by the bottom woven mesh 29, and the bottom woven mesh 29 is similarly attached to the original metal top frame 25 by a metal bottom frame 30, and is also clamped to the electronic drum frame 26.
