Description

Technical Field

[0001] The utility model relates to the technical field of electronic musical instruments, and specifically relates to an electronic bass drum. Background Art

[0002] The bass drum is a foot-operated bass drum in a drum kit. It is played by stepping on the pedal to drive the drumstick to strike the drumhead. It is the main low-frequency tone in a drum set, used to highlight the rhythm and groove. Traditional bass drums are large in size, not only occupying a large amount of space, but also causing a lot of noise, and need to be practiced in a well-soundproofed environment. However, electronic bass drums do not have these disadvantages. Therefore, electronic bass drums are becoming more and more popular among people.

[0003] An electronic bass drum usually includes a drum bottom, a drum barrel, and a drumhead. A sensor is provided inside the drum barrel. When the drumstick strikes the drumhead, the vibration is transmitted to the sensor. The sensor transmits the received signal to an external sound source and generates a corresponding tone. In order to ensure that the sensor can accurately receive the vibration signal, the drumhead needs to be in contact with the sensor. However, this will cause the direct impact of the drumstick on the sensor, resulting in damage to the sensor and reducing the service life of the electronic bass drum. To avoid damage to the sensor, there is usually a gap between the drumhead and the sensor, and the vibration transmission effect is poor, which causes the sensor to not accurately output the signal and the generated tone is not standard. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an electronic bass drum that can accurately output signals and has a long service life.

[0005] The technical solution of the utility model is to provide an electronic bass drum with the following structure:

[0006] It includes a support, an electronic drum body and a drumstick assembly arranged on the support. The drumstick assembly is used to strike the electronic drum body. The electronic drum body includes a drum barrel, a drumhead and a drum bottom connected to both ends of the drum barrel. A sensor and an elastic transmission layer are provided inside the drum barrel. The sensor is connected to the drum bottom, and both ends of the elastic transmission layer are respectively attached to the drumhead and the sensor, and are used to transmit the vibration of the drumhead to the sensor.

[0007] After adopting the above structure, compared with the prior art, the electronic bass drum of the utility model has the following advantages:

[0008] When the drumstick assembly strikes the drumhead, the vibration received by the drumhead will be transmitted to the sensor through the elastic transmission layer. While ensuring the accurate transmission of the vibration signal, it can also prevent the sensor from being directly impacted by the drumstick assembly and avoid damage to the sensor, thereby improving the service life of the product.

[0009] Preferably, a metal sheet is connected to one end face of the sensor facing the elastic transfer layer, and the cross-sectional shape of the metal sheet is the same as the cross-sectional shape of the elastic transfer layer. This allows the sensor to better contact the elastic transfer layer (25), thereby improving the accuracy of sensor detection.

[0010] Preferably, the elastic transmission layer includes an elastic portion and two hard portions, and the two hard portions are respectively connected to both end surfaces of the elastic portion.

[0011] Preferably, the support comprises a base and a bracket, and the base and the bracket are detachably connected by bolts. The support is configured as two parts, the base and the bracket, which can be disassembled into two flat plate-shaped parts during transportation, thereby reducing the occupied space and facilitating transportation.

[0012] Preferably, the bracket is integrally formed with the drum bottom, which can reduce the processing procedures and assembly steps, thus saving labor costs.

[0013] Preferably, the drumstick assembly comprises a frame, a drumstick and a pedal, wherein the drumstick is rotatably connected to the frame, one end of the pedal is hinged to the frame, and the other end is transmission-connected to the drumstick for driving the drumstick to rotate and strike the electronic drum body.

[0014] Preferably, a driving wheel is provided on the rotating shaft of the drumstick, and the driving wheel is connected to the pedal through a chain. In an initial state, a half circle of chain is wound around the driving wheel; one end of the drumstick rotating shaft is connected to a radially extending connecting handle, and the free end of the connecting handle is connected to the frame through a reset spring.

[0015] Preferably, the frame body is rotatably connected to one end of the base with a clamping plate for clamping on the base; a torsion spring is sleeved on the rotating shaft of the clamping plate, one end of the torsion spring is connected to the clamping plate, and the other end is connected to the frame body. The clamping plate can quickly realize the connection between the frame body and the base, and the installation is simple and convenient.

[0016] Preferably, the base has a ridge at one end facing the frame, and the clamp has a block at one end facing the base. The block is clamped on a side of the ridge away from the frame to prevent the clamp from falling off the base. BRIEF DESCRIPTION OF THE DRAWINGS
