Description

Technical Field

[0001] This invention relates to the field of musical instruments, specifically to a sound-producing instrument that reduces noise. Background Technology

[0002] With the development of technology, the application of large-scale integrated circuits is becoming more and more widespread. Traditional musical instruments such as electric guitars, electronic keyboards, and electronic drums have gradually evolved from relying solely on mechanical vibrations to produce sound electronically.

[0003] Because the sound of electronic musical instruments is simulated by a signal feedback and then emitted by a speaker, with the speaker being the main sound source, the sound produced by the instrument itself during operation can become noise and interference, affecting the performance. This effect is particularly pronounced on percussion instruments. Summary of the Invention

[0004] The purpose of this invention is to provide an electronic sound-producing musical instrument that reduces noise from the instrument itself during performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A noise-reducing musical instrument includes a drum plate, a drumhead, and a pressure plate. The bottom of the drum plate is provided with a fixing ring for connecting a fixed bracket. The pressure plate and the drum plate are connected by a pressure plate fixing screw. The drumhead is clamped and fixed between the pressure plate and the drum plate. A sensor is fixed inside the drum plate on the lower side of the drumhead to sense the vibration of the drumhead. The instrument is characterized in that an extended support rod is provided around the circumference of the drumhead. The drum plate and the pressure plate are respectively provided with elastic buffer connectors and pressing members to float and clamp the support rod from the upper and lower sides.

[0007] As a further aspect of the present invention: the drum disc includes a disc body, a mounting base and reinforcing ribs. The mounting base is provided in the center of the disc body. A sensor is fixed on the mounting base by a sensor fixing screw. Reinforcing ribs extending to the edge of the disc body are distributed circumferentially on the outer side of the mounting base. The tail end of the reinforcing ribs is vertically connected to a buffer connector for supporting the drum surface.

[0008] As a further aspect of the present invention: the disc structure between the reinforcing ribs is provided with a mounting groove corresponding to the shape of the bottom surface of the buffer connector, and a vertical screw hole is recessed in the center of the mounting groove, and the buffer connector is fixed in the mounting groove by the connector fixing screw.

[0009] As a further aspect of the present invention: the buffer connector is composed of an mounting part, a collapsible part, a supporting part, and a guiding part. The buffer connector is in the shape of an inverted crescent moon. The bottom is the mounting part, which is used to connect with the drum plate. The top is the supporting part, which is used to support the drum surface structure. The mounting part and the supporting part are connected by the collapsible part to form an integral structure. The collapsible part is a laterally bent bending structure that can collapse in the vertical direction. The supporting part is provided with outwardly bent guiding parts on both sides to guide the drum surface structure.

[0010] As a further aspect of the present invention: a through hole is provided in the center of the support part and the mounting part, and the front end of the connecting member fixing screw is threadedly connected to the threaded hole in the mounting slot through the through hole.

[0011] As a further aspect of the present invention, the through hole of the support portion is a two-stage stepped countersunk hole.

[0012] As a further aspect of the present invention: the drum surface includes a drum ring, a mesh surface and a bushing. The drum ring has an annular structure, and the mesh surface is fixed on the inner side by a bushing with an adjustable diameter. Extended support rods are provided in the circumferential direction of the drum ring and the buffer connector.

[0013] As a further aspect of the present invention, the outer side of the support rod is wrapped with a rubber sleeve.

[0014] Beneficial effects

[0015] 1. The drumhead of the present invention is provided with an extended support rod in the circumferential direction. The drum plate and the pressure plate are respectively provided with elastic buffer connectors and pressure members to float and clamp the support rod from the upper and lower sides. By floating and clamping the support rod from the upper and lower sides with elastic buffer connectors and pressure members, energy is absorbed by floating clamping, reducing the transmission of impact force to the drum plate and the pressure plate, reducing resonance, and reducing noise.

[0016] 2. The front end of the connecting screw of the present invention is threadedly connected to the threaded hole in the mounting slot through the through hole of the buffer connecting piece. Through the setting of the through hole, the connecting screw and the buffer connecting piece are in a limited contact. By adjusting the threaded connection depth between the front end and the threaded hole, the buffer connecting piece can be compressed by the connecting screw, thereby adjusting the initial compression degree of the buffer connecting piece and thus adjusting the softness or hardness of the impact feel.

[0017] 3. In this invention, an annular sound-absorbing foam is embedded on the outer side of the sensor inside the drum plate. The sound-absorbing foam fills the cavity between the drum plate and the drumhead, reducing the cavity volume and the amplification effect of the cavity on the vibration noise of the drumhead. The sound-absorbing foam also absorbs the vibration noise generated by the drumhead, reducing the impact of noise on the performance. Attached Figure Description

[0030] This embodiment provides a sound-producing instrument that reduces noise, such as... Figure 3 As shown, it includes a drum plate 1, a drum surface 7, and a pressure plate 8. The bottom of the drum plate 1 is provided with a fixing ring 2 for connecting a fixing bracket. The pressure plate 8 and the drum plate 1 are connected by a pressure plate fixing screw 9. The drum surface 7 is clamped and fixed between the pressure plate 8 and the drum plate 1. A sensor 5 is fixed inside the drum plate 1 on the lower side of the drum surface 7 to sense the vibration of the drum surface 7. The drum surface 7 is characterized by having an extended support rod 72 in the circumference of the drum surface 7. The drum plate 1 and the pressure plate 8 are respectively provided with an elastic buffer connector 3 and a lower pressing member 82 to float and clamp the support rod 72 from the upper and lower sides.

[0031] By using the elastic buffer connector 3 and the pressure plate 82 to float and clamp the support rod 72 from the top and bottom sides, the energy is absorbed by the floating clamp, reducing the transmission of the impact force to the drum plate 1 and the pressure plate 8, reducing resonance, and thus reducing noise.

[0032] Among them, such as Figure 4 As shown, the drum 1 includes a disc body 11, a mounting base 12, and reinforcing ribs 13. The mounting base 13 is located in the center of the disc body 11. A sensor 5 is fixed to the mounting base 13 by a sensor fixing screw 6. Reinforcing ribs 13 extending to the edge of the disc body 11 are distributed circumferentially on the outer side of the mounting base 12 to enhance the structural strength of the disc body 11. A buffer connector 3 for supporting the drum surface 7 is vertically connected to the tail end of the reinforcing rib 13.

[0033] Specifically, the disc body 11 structure between the reinforcing ribs 13 is provided with a mounting slot 14 corresponding to the shape of the bottom surface of the buffer connector 3. A vertical screw hole is recessed in the center of the mounting slot 14, and the buffer connector 3 is fixed in the mounting slot 14 by the connector fixing screw 4.

[0034] Among them, such as Figure 5 As shown, the buffer connector 3 is composed of a mounting part 31, a collapsible part 32, a supporting part 33, and a guiding part 34. The buffer connector 3 is in the shape of an inverted crescent moon. The bottom is the mounting part 31, which is used to connect with the drum plate 7. The top is the supporting part 33, which is used to support the structure of the drum surface 7. The mounting part 31 and the supporting part 33 are connected by the collapsible part 32 to form an integral structure. The collapsible part 32 is a bending structure that can be bent laterally and can be collapsed in the vertical direction. The supporting part 33 is provided with outwardly bent guiding parts 34 on both sides to guide the structure of the drum surface 7.

[0035] By utilizing the collapsible portion 32 of the buffer connector 3, when the impact generated by the strike is transmitted to the collapsible portion 32, the energy is absorbed by the collapsible portion, reducing the transmission of the impact force, avoiding resonance of the drum plate 1 structure, and reducing noise.

[0036] Furthermore, a through hole is provided in the center of the support part 33 and the mounting part 31, and the front end of the connecting fastener screw 4 is threadedly connected to the threaded hole in the mounting slot 14 through the through hole.

[0037] With the through hole, the connecting screw 4 and the buffer connector 3 are in a limiting contact. By adjusting the thread connection depth between the front end and the threaded hole, the connecting screw 4 can drive the buffer connector 3 to compress, thereby adjusting the initial compression degree of the buffer connector 3 and thus adjusting the softness or hardness of the impact feel.

[0038] Furthermore, the through hole of the support part 33 is a two-stage stepped countersunk hole. The stepped countersunk hole setting of the through hole hides the tail end structure of the connecting fastener screw 4, maintains the flatness of the support part 33, and improves the tightness of the connection with the drum surface 7.

[0039] Among them, such as Figure 7 As shown, the drumhead 7 includes a drum ring 71, a mesh surface 73, and a bushing 74. The drum ring 71 has a ring structure, and the mesh surface 73 is fixed to the inner side by a bushing 74 with an adjustable diameter. The drum ring 71 has extended support rods 72 corresponding to the buffer connector 3 in the circumferential direction. By setting the support rods 72 around the circumference, the connection point of the drumhead 7 is moved away from the striking position, which extends the transmission path of the striking force on the mesh surface 73, improves the absorption of the striking force by the mesh surface 73, reduces the impact, and plays a role in noise reduction.

[0040] Specifically, the outer side of the support rod 72 is wrapped with a rubber sleeve 75. The rubber sleeve 75 serves as a buffer connection between the support rod 72 and the buffer connector 3 and the pressing component 82, which absorbs energy and improves the flexibility of the drumhead 7 connection, preventing the striking feel from being too hard.

[0041] Among them, such as Figure 8 As shown, the pressure plate 8 includes a ring body 81 and a lower pressure member 82. The ring body 81 is an annular structure with a diameter larger than that of the drum surface 7. The lower side of the inner wall is provided with a downwardly tilted lower pressure member 82 at the position corresponding to the buffer connector 3. With the setting of the lower pressure member 82, when the pressure plate 8 is fixedly connected to the drum plate 1 by the pressure plate fixing screw 9, the lower pressure member 82 can fix the support rod 72 of the drum surface 7 from the top. The tilted setting of the lower pressure member 82 gives the lower pressure member 82 the possibility of elastic deformation, maintaining the floating clamping of the support rod 72. Through the floating clamping energy absorption, the resonance of the pressure plate 8 is reduced and the noise is reduced.

[0042] Furthermore, when the pressure plate 8 is locked by the pressure plate fixing screw 9, the lower pressing part 82 is in a compressed state due to the reaction force of the drum surface 7. That is, there is a margin in the contact between the lower pressing part 82 and the drum surface 7 support rod 72. Even if the drum surface 7 is hit and sinks or the height of the drum surface 7 is actively adjusted, the lower pressing part 82 will always contact the support rod 72 to clamp and fix the support rod 72, ensuring stability.

[0043] Among them, such as Figure 1 As shown, an annular sound-absorbing foam 10 is embedded on the outer side of the sensor 5 inside the drum plate 1 body 11. The sound-absorbing foam 10 fills the cavity between the drum plate 1 and the drum surface 7, reducing the cavity volume and the amplification effect of the cavity on the vibration noise of the drum surface 7. The sound-absorbing foam 10 also absorbs the vibration noise generated by the drum surface 7, reducing the impact of noise on the performance.

[0044] When implementing the technical solution described in this embodiment, when the drumhead 7 is struck, the striking force is transmitted from the striking point to fixed positions around the drumhead 7. By circumferentially floating and clamping the support rod 72, the connection point of the drumhead 7 is moved away from the striking position, extending the transmission path length of the striking force on the mesh 73, improving the absorption of the striking force by the mesh 73, reducing the impact, and playing a noise reduction role. The foam 10 between the drum plate 1 and the drumhead 7 fills the cavity, reducing the cavity volume and reducing the amplification effect of the cavity on the vibration noise of the drumhead 7. The sound-absorbing foam 10 also absorbs the vibration noise generated by the drumhead 7. When the striking force is transmitted to the position of the buffer connector 3, the energy absorption of the collapsing part 32 and the pressing part 82 is reduced, reducing the transmission of the striking force to the drum plate 1 and the pressing plate 8 side, avoiding structural resonance, further reducing the noise generated when the instrument body is used, and ensuring the performance quality.
