Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic drums, and in particular to an electronic drum triggering structure. Background Technology
[0002] An electronic drum kit is a modern musical instrument that uses electronic technology to simulate the sounds of traditional percussion instruments. It captures the striking motion through sensors (triggers) and then generates the sound through a sound source module. It is typically equipped with headphones or speaker output and is suitable for quiet practice or stage performance. Current electronic drum kits usually have a trigger mechanism that places a sponge between the drumhead and the drum plate, with a buzzer placed in the middle of the sponge. However, this structure suffers from problems such as unresponsive buzzer triggers, poor trigger signals, and the large area of sponge in contact with the drumhead, which can easily generate friction noise. Utility Model Content
[0003] To overcome the above problems, this utility model provides an electronic drum triggering structure. The technical solution adopted by this utility model to solve its technical problems is as follows:
[0004] An electronic drum triggering structure includes a first sponge disposed on the bottom surface of the drum plate, an annular sponge disposed on the first sponge, a buzzer disposed on the annular sponge, and a second sponge disposed on the buzzer. The top surface area of the second sponge is smaller than the bottom surface area of the second sponge, the bottom surface of the second sponge is attached to the buzzer, and the top surface of the second sponge abuts against the drum surface.
[0005] Furthermore, the second sponge is frustum-shaped.
[0006] Furthermore, the first sponge, the annular sponge, the buzzer plate, and the second sponge are arranged coaxially, one above the other.
[0007] Furthermore, the hardness of the first sponge is greater than that of the ring sponge, and the hardness of the ring sponge is greater than that of the second sponge.
[0008] Furthermore, a third sponge is provided between the drum plate and the drumhead, and the third sponge is adjacent to the first sponge.
[0009] Furthermore, the first sponge, the ring sponge, the second sponge, and the third sponge are all made of EVA material.
[0010] Furthermore, the distance from the central axis of the first sponge, the ring sponge, the buzzer plate, and the second sponge to the central axis of the drumhead and the drum plate is 50-100mm.
[0011] Furthermore, several electronic drum triggering structures are arranged around the central axis of the drumhead and drum plate.
[0012] The beneficial effects of this utility model are:
[0013] The structure includes a first sponge disposed on the bottom surface of the drum, an annular sponge disposed on the first sponge, a buzzer disposed on the annular sponge, and a second sponge disposed on the buzzer. The top surface area of the second sponge is smaller than the bottom surface area of the second sponge. The bottom surface of the second sponge is attached to the buzzer, and the top surface of the second sponge abuts against the drum surface. In this triggering structure, the buzzer disposed on the annular sponge has a suspended part below it, which makes the buzzer more likely to bend and improves the triggering sensitivity of the buzzer. At the same time, the small contact area between the second sponge and the drum surface reduces friction noise when the drum surface is extremely large. Attached Figure Description

[0020] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of the "electronic drum triggering structure" of this utility model is provided in conjunction with the accompanying drawings.
[0021] See Figures 1-3 In this embodiment, the electronic drum triggering structure includes a first sponge 101 disposed on the bottom surface of the drum plate 100, an annular sponge 102 disposed on the first sponge 101, a buzzer 103 disposed on the annular sponge 102, and a second sponge 104 disposed on the buzzer 103. Preferably, the bottom surface of the drum plate 100 and the first sponge 101, the first sponge 101 and the annular sponge 102, the annular sponge 102 and the buzzer 103, and the buzzer 103 and the second sponge 104 are all connected and fixed by adhesive bonding. The top surface area of the second sponge 104 is smaller than the bottom surface area of the second sponge 104. Preferably, the second sponge 104 is frustum-shaped. The bottom surface of the second sponge 104 is attached to the buzzer 103, and the top surface of the second sponge 104 abuts against the drum surface 105.
[0022] This electronic drum triggering structure uses a ring-shaped sponge 102 to form a hollow area at the bottom of the buzzer 103. When the impact force on the drumhead is transmitted to the buzzer 103 through the sponge, the buzzer 103 is more likely to bend, improving the triggering sensitivity of the buzzer 103 and enhancing the triggering signal. Furthermore, the top area of the second sponge 104 is smaller than its bottom area, reducing the contact area between the top surface of the second sponge 104 and the drumhead 105, thus reducing friction noise. At the same time, because the second sponge 104 is shaped like a frustum with a smaller top and a larger bottom, and the bottom surface of the frustum is in contact with the buzzer 103, the force on the top surface of the second sponge 104 will be evenly distributed downwards to the bottom surface of the frustum, avoiding localized stress on the buzzer 103 and the occurrence of popping points.
[0023] More specifically, in this embodiment, the first sponge 101, the annular sponge 102, the buzzer 103, and the second sponge 104 are arranged coaxially and vertically, which ensures that the force on the drum surface 105 is transmitted downwards evenly. Preferably, the hardness of the first sponge 101 is greater than that of the annular sponge 102, and the hardness of the annular sponge 102 is greater than that of the second sponge 104. This makes it easier for the second sponge 104 to undergo elastic deformation under force, and the annular sponge 102 can provide better support for the buzzer 103, improving the deformation sensitivity of the buzzer 103 and the signal triggering sensitivity. Furthermore, the first sponge 101, located at the bottom, can filter out the vibration force of the drum 100, so that the buzzer 103 is not affected by the vibration of the drum 100, reducing the interference to the buzzer 103.
[0024] See further Figure 2 and Figure 3 In this embodiment, a third sponge 106 is also provided between the drum plate 100 and the drum surface 105. The third sponge 106 is adjacent to the first sponge 101. The third sponge 106 enhances the stability of the first sponge 101 and better absorbs the vibration force of the drum plate 100. Preferably, the first sponge 101, the annular sponge 102, the second sponge 104 and the third sponge 106 are all made of EVA material.
[0025] More specifically, in this embodiment, the distance from the central axis of the first sponge 101, the annular sponge 102, the buzzer 103, and the second sponge 104 to the central axis of the drum surface 105 and the drum plate 100 is 50-100mm. This setting of the trigger structure off-center from the center of the drum surface 105 avoids the position of the hammer, preventing popping sounds and extending the service life of the trigger structure. Combined with the frustum-shaped second sponge 104, it further reduces the probability of the trigger structure being directly hit by the hammer, further improving the service life of the trigger structure.
[0026] Furthermore, in some embodiments, several trigger structures may be used simultaneously in the electronic drum. The several electronic drum trigger structures are arranged around the central axis of the drum surface 105 and the drum plate 100, and the trigger structures are evenly distributed to improve the signal triggering sensitivity of the trigger structures throughout the entire drum surface 105.
