Description

Technical Field

[0001] This utility model belongs to the field of electronic drum technology, and particularly relates to a side-mounted trigger and an electronic drum. Background Technology

[0002] A drum is a common musical instrument. A conventional drum consists of upper and lower drumheads, a drum body forming the drum cavity between the upper and lower drumheads, and a pressure ring that fixes the drumheads to the drum body. Traditional drums produce sound by striking the drumheads with drumsticks. With the rise of electronic musical instruments, electronic drums have emerged. Electronic drums use independent sensors placed at different locations to acquire strike signals from different positions. These sensors convert the strike signals into electrical signals, and a data processing module processes the received electrical signals to generate an audio signal output. However, currently, there is no side-mounted trigger that can simultaneously acquire strike signals from different positions. Utility Model Content

A connecting plate is connected to the open end of the mounting body. The connecting plate is tightly fitted to the drum body and is detachably connected. The mounting body, the mounting plate, and the drum body together form a mounting cavity. The first sensor is arranged in the mounting cavity. The mounting plate is in contact with the vibration isolation pad.

[0006] Optionally, the side-mounted trigger further includes an adapter, the input end of which is connected to the signals of the first sensor and the second sensor respectively, and the output end of which is connected to the signal of an external device.

[0007] Optionally, the output end of the adapter is a cylindrical structure, and an installation hole is provided on the inner wall of the mounting housing. The adapter is detachably connected to the mounting cavity, and the output end of the adapter extends out of the mounting cavity through the installation hole.

[0008] Optionally, the drum body is provided with a snap-fit ​​hole, the adapter is detachably connected to the mounting cavity, and the output end of the adapter extends through the snap-fit ​​hole and out of the mounting cavity and the inside of the drum body.

[0013] Compared with the prior art, the present invention has the following advantages and technical effects:

[0014] When this invention is in operation, when the drumhead is struck, the drumhead vibrates. Since the vibration pad is in contact with the drumhead, the vibration pad can sense the drumhead vibration and generate vibration, and transmit this vibration to the second sensor.

Detailed Implementation

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this utility model can be combined with each other. The described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Referring to the accompanying drawings, this utility model provides a side-mounted trigger for acquiring vibration signals from the drumhead 11 and the drum body 12. It includes a mounting housing 21, which is detachably connected to the drum body 12. A first sensor 22 is detachably connected inside the mounting housing 21. A vibration pad 25, a second sensor 24, and a vibration isolation pad 23 are sequentially arranged on one side of the mounting housing 21. The vibration isolation pad 23 is in contact with the mounting housing 21. The vibration pad 25 abuts against the drumhead 11.

[0024] When this invention is in operation, when the drumhead 11 is struck, the drumhead 11 vibrates. Since the vibration pad 25 is in contact with the drumhead 11, the vibration pad 25 can sense the vibration of the drumhead 11 and generate vibration, and transmit the vibration to the second sensor 24. The second sensor 24 converts the vibration signal into an electrical signal. When the drum body 12 is struck, the drum body 12 vibrates. Since the mounting housing 21 is detachably connected to the drum body 12, the mounting housing 12 can sense the vibration of the drum body 12 and generate vibration, and transmit the vibration to the first sensor 22, which is detachably connected to the mounting housing 21. The first sensor 22 converts the vibration signal into an electrical signal. This invention can simultaneously acquire the vibration signals of the drumhead 11 and the drum body 12 through the same side-mounted trigger. Furthermore, since a vibration isolation pad 23 is provided between the first sensor 22 and the second sensor 24, the vibration isolation pad 23 can absorb the vibration transmitted to itself, preventing interference between the vibration of the drumhead 11 and the vibration of the drum body 12, and ensuring the accuracy of the measurements by the first sensor 22 and the second sensor 24.

[0025] In a further optimized design, the mounting housing 21 includes a detachably connected mounting body 211 and a mounting plate 212. The mounting body 211 has an open end on the side near the drum body 12. A connecting plate 213 is connected to the open end of the mounting body 211. The connecting plate 213 is tightly fitted to the drum body 12 and is detachably connected. The mounting body 211, the mounting plate 212, and the drum body 12 together form a mounting cavity 214. The first sensor 22 is arranged in the mounting cavity 214. The mounting plate 212 is in contact with the vibration isolation pad 23. In this embodiment, the mounting housing 21 is configured as a split structure, comprising a detachably connected mounting body 211 and a mounting plate 212. The mounting body 211, mounting plate 212, and drum body 12 together form a mounting cavity 214, and the first sensor 22 is arranged within the mounting cavity 214. In this embodiment, a connecting plate 213 is connected to the open end of the mounting body 211, and the connecting plate 213 is tightly fitted to and detachably connected to the drum body 12. The connecting plate 213 increases the contact area between the mounting housing 21 and the drum body 12, ensuring that the mounting housing 21 can accurately sense and acquire the vibration of the drum body 12, and ensuring the accuracy of the measurement by the first sensor 22. In some embodiments, the connecting plate 213 is an arc-shaped plate, which is adapted to the drum body 12 it contacts, ensuring that the connecting plate 213 and the drum body 12 are tightly fitted.

[0026] In some embodiments, the first sensor 22 and the second sensor 24 can be directly connected to external devices. However, this necessitates connecting each sensor separately to an external device during side-mounted trigger installation, resulting in low installation efficiency. A further optimization includes an adapter 26. The input of the adapter 26 is connected to the signals of the first sensor 22 and the second sensor 24, respectively, and the output of the adapter 26 is connected to the signal of an external device. In this embodiment, the input of the adapter 26 is connected to the signals of the first sensor 22 and the second sensor 24, respectively. The adapter 26 receives signals from the first sensor 22 and the second sensor 24 and transmits these signals to the external device. During installation, only the output of the adapter 26 needs to be connected to the signal of the external device, making operation convenient. In some embodiments, the output of the adapter 26 is connected to the external device via a novel signal interface structure. This signal interface structure is an existing mechanism and will not be described in detail here.

[0027] In this embodiment, the output end of the adapter 26 can be located inside or outside the drum cavity 13. When the output end of the adapter 26 can be located inside the drum cavity 13, the output end of the adapter 26 has a cylindrical structure, and a mounting hole 215 is provided on the inner wall of the mounting housing 21. The adapter 26 is detachably connected to the mounting cavity 214, and the output end of the adapter 26 extends out of the mounting cavity 214 through the mounting hole 215 and enters the drum cavity 13. The output end of the adapter 26 is connected to the signal of an external device through a signal interface structure. In this embodiment, the external device can be located inside the drum cavity 13. In some other embodiments, the output end of the adapter 26 is located outside the drum cavity 13, and a snap-fit ​​hole is provided on the drum body 12. The adapter 26 is detachably connected to the mounting cavity 214, and the output end of the adapter 26 extends through the snap-fit ​​hole and out of the mounting cavity 214 and the inside of the drum body 12, thus coming into contact with the external environment. Operators can directly connect the output end of the adapter 26 to external devices via the signal interface structure. In this case, the external device is located outside the drum cavity 13, making connection convenient. This embodiment includes these two installation methods, improving the adaptability of the side-mounted trigger and making it suitable for different structures of new and old electronic drums.

[0028] Further optimization involves using a tower-like structure for the vibration pad 25. This structure comprises several cylinders connected in sequence, with the diameter of each cylinder gradually increasing from the end closest to the drum surface 11 towards the end closest to the mounting housing 21. This reduces the contact area between the vibration pad 25 and the drum surface 11, concentrating the force exerted by the drum surface 11 on the vibration pad 25 and improving the accuracy of vibration transmission by the vibration pad 25, thus enhancing the accuracy of the measurement by the second sensor 24. In some embodiments, the vibration pad 25 can also be conical or frustum-shaped, with the tip of the cone or the smaller end face of the frustum connected to the drum surface 11. This further reduces the contact area between the vibration pad 25 and the drum surface 11, thereby improving the accuracy of the measurement by the second sensor 24.

[0029] Further optimization of the design involves using vibration isolation pad 23 as vibration isolation cotton, and ensuring that the hardness of vibration pad 25 is greater than that of vibration isolation pad 23. This guarantees that vibration pad 25 can sense and generate vibration from drum surface 11, transmitting this vibration to the second sensor 24. Vibration isolation pad 23 can absorb the vibration transmitted from the second sensor 24, as well as the vibration transmitted from mounting housing 21, achieving a vibration isolation effect. Preferably, an iron plate 27 is provided between the second sensor 24 and vibration isolation pad 23. The first sensor 22 and the second sensor 24 typically employ piezoelectric ceramic buzzers, usually including copper and ceramic plates. The iron plate 27 amplifies the vibration of the second sensor 24, enhancing its signal reception capability and reducing the impact of vibration isolation pad 23 on the second sensor 24. In some embodiments, the vibration pad 25 and vibration isolation pad 23 are made of materials such as polyurethane and epoxy resin.

[0030] An electronic drum includes an electronic drum body and a side-mounted trigger. The electronic drum body includes a detachably connected drum body 12 and drumhead 11, with a drum cavity 13 disposed inside the drum body 12 and drumhead 11. The side-mounted trigger is disposed inside the drum cavity 13, and a mounting housing 21 is detachably connected to the drum body 12. A vibration pad 25 abuts against the drumhead 11. In this embodiment, vibration signals from the drumhead 11 and drum body 12 can be simultaneously acquired using the same side-mounted trigger. Furthermore, since a vibration isolation pad 23 is disposed between the first sensor 22 and the second sensor 24, the vibration isolation pad 23 can absorb the vibration transmitted to itself, preventing interference between the vibrations of the drumhead 11 and the drum body 12, and ensuring the accuracy of the measurements taken by the first sensor 22 and the second sensor 24. In some embodiments, an external device includes a data processing module, which is signal-connected to the first sensor 22 and the second sensor 24. The data processing module processes the received electrical signals to generate an audio signal output.
