Description

Technical Field

[0001] This utility model relates to the field of electronic drums, specifically to an electronic drum trigger. Background Technology

[0002] Electronic drums need to simultaneously receive and sense both the player's striking signals on the drumhead (side hits) and the striking signals on the drumhead. These striking signals (vibration signals) are then converted into corresponding electrical signals, which are then converted into audio signals by a signal amplifier connected to the drum unit and emitted as sound. Current electronic drum products typically have separate triggers installed on the drumhead and drumhead. While this method can receive both signals, the separate installation is inconvenient, increasing the overall complexity of the drum unit and making it difficult to install and use. Integrating both triggers into a single structure results in the triggers being unable to effectively distinguish between vibrations originating from the drumhead and the drumhead, leading to serious false triggering problems and rendering the drum unit unusable. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an electronic drum trigger, comprising:

[0004] The side-impact trigger assembly includes a support frame and a side-impact trigger. The support frame is fixedly installed on the drum wall or drum bottom inside the drum cavity of the electronic drum. The side-impact trigger is fixedly installed on the support frame. The side-impact trigger is used to receive the vibration of the support frame and convert it into an electrical signal.

[0005] A drumhead trigger assembly includes a trigger pad and a drumhead trigger. The drumhead trigger is mounted on the support frame.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Figure 1 This is a schematic diagram of the overall structure of the electronic drum trigger provided in this embodiment of the utility model; Figure 2 This is a structural diagram of the disassembled electronic drum trigger provided in this embodiment of the utility model.

[0025] like Figure 1 and Figure 2As shown, this utility model provides an electronic drum trigger, including a rim trigger assembly 1, a drumhead trigger assembly 2, and an isolation assembly 3. The rim trigger assembly 1 includes a support frame 11 and a rim trigger 12. The rim trigger 12 is mounted on the support frame 11. The support frame 11 is fixedly installed on the drum wall or drum bottom inside the drum cavity. Thus, the support frame 11 is fixedly connected to the drum rim. When the performer strikes the drum rim (rim strike), the vibration of the drum rim is transmitted to the support frame 11 fixedly connected to it. Then, the rim trigger 12 receives the vibration of the support frame 11 and converts it into an electrical signal to complete the rim trigger.

[0026] The drumhead trigger assembly 2 includes a trigger pad 21 and a drumhead trigger 22. The drumhead trigger 22 is mounted on the support frame 11. The two opposite sides of the trigger pad 21 abut against the drumhead and the drumhead trigger 22, respectively. When the performer strikes the drumhead, the vibration of the drumhead is transmitted to the trigger pad 21 that abuts against it. Then the drumhead trigger 22 receives the vibration of the trigger pad 21 and converts it into an electrical signal to complete the triggering of the drumhead strike.

[0027] By installing a side-impact trigger 12 and a drumhead trigger 22 on a support frame 11, with the support frame 11 fixedly connected to the drum rim and the drumhead trigger 22 abutting against the drumhead via a trigger pad 21, the trigger of this invention can simultaneously receive the player's strikes to both the drum rim and the drumhead. The trigger inside the drum cavity converts the strikes into electrical signals, which are then converted into sound signals and played through other electrical components, thus realizing the function of an electronic drum. During installation, it is only necessary to fix the support frame 11 in a suitable position on the drum body so that the support frame 11 can transmit the vibration of the drum rim, and simultaneously allow the trigger pad 21 to abut against the drumhead so that the trigger pad 21 can transmit the vibration of the drumhead. The overall structure is simpler and easier to install.

[0028] Furthermore, an isolation component 3 is provided between the drumhead trigger 22 and the support frame 11. The isolation component 3 is used to weaken the vibration transmission between the drumhead trigger 22 and the support frame 11. In this way, when the player strikes the drum rim, the support frame 11 vibrates, and the rim trigger 12 fixedly installed on the support frame 11 is triggered. However, the drumhead trigger 22 cannot be triggered due to the obstruction of the isolation component 3. Similarly, when the player strikes the drumhead, the trigger pad 21 vibrates, and the drumhead trigger 22 is triggered. However, the rim trigger 12 (support frame 11) cannot be triggered due to the obstruction of the isolation component 3. Therefore, the electronic drum can clearly distinguish the player's intention, and the strikes on the drum rim and the strikes on the drumhead can produce clear sounds, thereby ensuring the performance effect.

[0029] like Figure 1 and Figure 2As shown, in one preferred embodiment, the isolation component 3 includes a vibration isolation pad 31, which is disposed between the support frame 11 and the drumhead trigger 22. The vibration isolation pad 31 is made of a flexible and vibration-absorbing material, such as cotton, rubber, polyurethane, or epoxy resin. In this way, the vibration isolation pad 31 can provide a certain support for the drumhead trigger 22 and the trigger pad 21, so that they abut against the drumhead. When the support frame 11 vibrates, the side trigger 12 fixedly installed on the support frame 11 can generate an electrical signal based on the vibration, while the drumhead trigger 22 cannot receive effective vibration due to the vibration absorption function of the vibration isolation pad 31 and therefore cannot be triggered.

[0030] Furthermore, the isolation assembly 3 also includes an isolation plate 32. The isolation pad 31, the drumhead trigger 22, and the trigger pad 21 are all connected to the support frame 11 through the isolation plate 32. The isolation plate 32 and the support frame 11 can be connected by a spring. The spring connection can effectively separate the mutual transmission of vibration between the isolation plate 32 and the support frame 11. The connection between the drumhead trigger 22 and the support frame 11 can also refer to some existing connection methods with vibration isolation and vibration absorption functions, as long as it can ensure that the drumhead trigger 22 and the trigger pad 21 abut against the drumhead, and that the vibrations received by the drumhead trigger 22 and the side trigger 12 do not interfere with each other. This will not be elaborated here.

[0031] Figure 3a and Figure 3b This is a schematic diagram of the support frame for the electronic drum trigger provided in this embodiment of the utility model.

[0032] like Figure 3a and Figure 3b As shown, in one preferred embodiment, the support frame 11 includes a plurality of connecting blocks 111, which are circumferentially spaced on the drum wall of the drum cavity. The support frame 11 also includes connecting legs 113 and a central connecting frame 114. The central connecting frame 114 is mounted on the connecting blocks 111 via the connecting legs 113, so that the central connecting frame 114 is located in the center of the drum cavity. The side-strike trigger 12 is mounted on the central connecting frame 114. By setting the central connecting frame 114 in the center of the drum cavity and fixing it to the drum body via multiple connecting legs 113 and connecting blocks 111, the player's strikes to various positions on the circumferential drum edge can be effectively transmitted to the side-strike trigger 12 through the connecting blocks 111, connecting legs 113, and central connecting frame 114, thereby improving the effect of the side-strike trigger.

[0033] In addition, Figure 3aIn the embodiment shown, there are two connecting blocks 111 and the connecting legs 113 are in a straight line shape. In some other embodiments, there may be multiple connecting blocks 111 and the connecting legs 113 are radially extending from the central connecting frame 114 to multiple connecting blocks 111, which can further improve the accuracy of edge-click sensing by the support frame 11 and the edge-click trigger 12.

[0034] Furthermore, in one preferred embodiment, the mounting height of the support frame 11 within the drum cavity is adjustable. Therefore, the height of the drumhead trigger 22 and the trigger pad 21 mounted on the support frame 11 is adjustable. By adjusting this height, the trigger pad 21 and the drumhead trigger 22 can maintain good contact with the drumhead. At the same time, during the use of the electronic drum, the performer can also flexibly adjust the contact force between the trigger pad 21 and the drumhead according to their own playing habits and strength, thereby improving the performance of the electronic drum.

[0035] like Figure 3b As shown, a slot 1111 extending axially along the drum cavity is provided on the connecting block 111. The connecting leg 113 is connected to the slot 1111 via a connecting shaft 112, and the connecting shaft 112 can slide within the slot 1111, allowing the installation height of the connecting leg 113 and the central connecting frame 114 within the drum cavity to be adjustable. This, in turn, allows the installation height of the support frame 11 within the drum cavity to be adjustable. After the height is adjusted, the connecting shaft 112 can be fixed within the slot 1111 by means of screws or other methods, thus fixing the support frame 11 within the drum cavity. The method of fixing the connecting shaft 112 within the slot 1111 can refer to some existing technical solutions, which will not be elaborated here. Alternatively, the installation height of the support frame 11 can also be adjusted by making the installation height of the connecting block 111 on the drum wall adjustable. The adjustment of the installation height of the support frame 11 within the drum cavity can be achieved by selecting a suitable specific technical solution according to actual needs. The above content is only used to explain the content of this utility model and should not be considered as a limitation on the scope of protection.

[0036] like Figure 2 As shown, in one preferred embodiment, the edge trigger 22 includes a first sensor 121 and a first support pad 122, the first sensor 121 being fixedly mounted on the support frame 11 via the first support pad 122 (in... Figure 2In the illustrated embodiment, the first sensor 121 and the first support pad 122 are fixedly mounted on the central connecting frame 114. The first support pad 122 supports the first sensor 121 between the support frame 11 and the first sensor 121, providing good protection for the first sensor 121. Specifically, when the support frame 11 experiences significant vibration, its surface may undergo many instantaneous deformations. By using the first support pad 122 to connect the first sensor 121 to the support frame 11, the impact of these deformations on the physical structure of the first sensor 121 can be weakened, ensuring the structural stability of the first sensor 121. The first support pad 122 can be made of materials such as rigid foam, as long as it can transmit the vibration of the support frame 11 to the first sensor 121 and weaken the impact of the deformation of the support frame 11 on the structural stability of the first sensor 121.

[0037] In one preferred embodiment, the mounting positions of the first sensor 121 and the first support pad 122 on the support frame 11 are adjustable radially along the drum cavity. By changing the mounting positions of the first sensor 121 and the first support pad 122 on the support frame 11, the first sensor 121 can be moved closer to one side of the drum wall. Figure 3a In the embodiment shown, the first sensor 121 is closer to one of the connecting blocks, so that the edge strike on that side can be transmitted to the first sensor 121 more accurately and clearly. By flexibly adjusting the position of the first sensor 121, the applicability can be improved, which is more conducive to improving the performance effect.

[0038] In addition, such as Figure 3a As shown, the connecting leg 113 is a square tube or square rod, and the lower end of the central connecting frame 114 has a directional groove that mates with the connecting leg 113, allowing the central connecting frame 114 to slide on the connecting leg 113 and thus adjust the position of the first sensor 121. Simultaneously, by adjusting the position of the central connecting frame 114, the position of the drumhead trigger assembly 2 mounted above it can also be adjusted, further improving usability and enhancing performance.

[0039] Figure 4 This is a schematic diagram of the structure of the adapter board for the electronic drum trigger provided in this embodiment of the utility model.

[0040] like Figure 2 and Figure 4As shown, the drumhead trigger assembly 2 also includes an adapter plate 23. Multiple trigger pads 21 are disposed on the adapter plate 23, with opposite sides of each trigger pad 21 abutting against the drumhead and the adapter plate 23. The drumhead trigger 22 includes a second support pad 222 and a second sensor 221, with the second sensor 221 abutting against the adapter plate 23 via the second support pad 222. By setting the adapter plate 23, the drumhead trigger 22 can abut against multiple trigger pads 21 (i.e., via the adapter plate 23), making the drumhead trigger 22's vibration sensing of the drumhead more accurate and improving the performance of the electronic drum. Furthermore, similar to the first support pad 122, the second support pad 222 supports the second sensor 221 between the adapter plate 23 and the second sensor 221, providing good protection for the second sensor 221 and extending its service life.

[0041] In one preferred embodiment, a plurality of trigger pads 21 are symmetrically distributed relative to the axis of the drum cavity, and the adapter plate 23 is provided with a recess for installing a second support pad. When the adapter plate 23 is installed in the drum cavity, the recess is located at the center of the drum cavity.

[0042] like Figure 4 As shown, the adapter plate 23 has a central hole 231 in the middle and planetary holes 232 distributed circumferentially around the central hole 231. The central hole 231 is used to install the second support pad 222, and the planetary holes 232 are used to install the trigger pad 21. This arrangement increases the contact range and area between the trigger pad 21 and the drumhead. Furthermore, the second support pad 222 and the second sensor 221 are located at the center of the contact range between the trigger pad 21 and the drumhead, allowing the trigger pad 21 and the second support pad 222 to more accurately transmit the vibration of the drumhead to the second sensor 221, thus improving the performance.

[0043] In addition, Figure 2 and Figure 4 In the embodiment shown, the adapter plate 23 is in the shape of a delta wing, and the trigger pads 21 are disposed at the three ends of the delta wing. In some other embodiments, the adapter plate 23 may be in the shape of a cross or a star, or other shapes, which will not be described in detail here.

[0044] like Figure 2 and Figure 4 As shown, in one preferred embodiment, the adapter plate 23 has weight-reducing grooves or holes 233, making the adapter plate 23 hollow overall. This reduces the weight of the adapter plate 23 and its inertia, allowing it to better transmit the vibration of the drumhead to the second support pad 222 and the second sensor 221, thus improving the performance. The adapter plate 23 can also be made of materials with low density and good strength, such as nylon or carbon fiber, to further reduce its weight.

[0045] In one preferred embodiment, the support frame 11 is provided with a cable retaining groove, in which the connecting cables of the side trigger 12 and the drumhead trigger 22 can be secured and fixed. Figure 2 As shown, a first wire-clamping groove 1141 is provided on the central connecting frame 114, and a second wire-clamping groove 321 is provided on the isolation plate 32. By fixing the connecting cable in these wire-clamping grooves, the stability of the connection between the cable and the electrical components can be improved, and the cable can be prevented from shaking and touching the sensor in the drum cavity, which would cause the sensor to be falsely triggered.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered by the claims of this utility model.
