Description

Technical Field

[0001] The utility model belongs to the technical field of electronic musical instruments, and particularly relates to an electronic drum trigger assembly and an electronic drum head including the trigger assembly. Background Art

[0002] There is a significant difference in the timbre when a traditional drum is struck at the edge of the mesh head and when it is struck at the center plane of the mesh head. It is a sound effect with a natural and gradual transition. When playing, a natural timbre change will occur from the edge to the center of the drum head.

[0003] Currently, most of the drum heads of existing electronic drums on the market use a single piezoelectric ceramic sheet (sensor) to sense the percussion signal. In order to achieve both the drum surface percussion function and the rim shot function, some electronic drums install piezoelectric ceramic sheets (sensors) for the drum rim on one side of the inner wall of the drum cavity. In this way, when hitting, the magnitude of the percussion signal will be affected by the distance between the percussion point and the piezoelectric ceramic sheet (sensor). When the percussion point is in the area closer to the installation position of the piezoelectric ceramic sheet (sensor), the sensed signal is relatively weak, and the sound output by the sound source will be particularly loud; while when the percussion point is far from the installation position of the piezoelectric ceramic sheet (sensor), the sensed signal is relatively weak, and the sound output by the sound source will also be particularly slight. Therefore, when hitting the drum head, due to the different magnitudes of the electrical signals generated by hitting at different positions, it will lead to uneven signal conduction. Especially when hitting across the rim shot, the signal is unstable, sometimes there and sometimes not, intermittent, making the overall percussion effect unsatisfactory.

[0004] To overcome the above technical problems, Chinese patent document CN203858857U discloses an electronic drum structure. An independent bottom shell 4 is provided in the drum head part. A circular ring protrusion 41 is provided at the center position of the bottom shell body. A drum surface trigger device 5 is provided on the circular ring protrusion 41. A trigger device for the drum rim is provided in the recessed part 42 at the center of the circular ring protrusion 41. When hitting the edge of the electronic drum, the vibration of the bottom shell 4 is transmitted to the trigger device for the drum rim located at the center position of the bottom shell body, so that the percussion signal of the drum head rim shot can be received well, and the trigger of the drum rim is more uniform.

[0005] However, for the drum head structure of the above-mentioned electronic drum, since both the drum surface trigger device and the drum rim trigger device are located at the center position of the bottom shell, when hitting, the problem of signal crosstalk between the surface and the edge is likely to occur.

[0030] To this end, the following solutions are proposed:

[0031] Referring to Figure 1 and Figure 2 As shown, the present utility model provides an electronic drum trigger assembly 10, which is located in the drum of the electronic drum and arranged parallel to the drum surface of the electronic drum. It includes a trigger bracket 11 and a drum surface trigger assembly 12 and a drum edge trigger assembly 13 located on the trigger bracket 11. Among them, the trigger bracket 11 includes a circular bracket 111 located at the center of the drum and several skeletons 112 that radially extend with the circular bracket 111 as the center, are evenly distributed in a circumferential manner, and have the same length. The ends of the several skeletons 112 are fixed on the inner wall of the drum of the electronic drum. The drum surface trigger assembly 12 is arranged on the circular bracket 111, and several drum edge trigger assemblies 13 are symmetrically arranged on the ends of at least two of the skeletons 112.

[0032] As a preferred embodiment of the present utility model, in the electronic drum trigger assembly of the present utility model, the trigger bracket 11 is in the shape of a disc fixed in the drum of the electronic drum, and six skeletons 112 evenly distributed in a circumferential manner are provided. On these six skeletons 112, three drum edge trigger assemblies 13 are provided, and each drum edge trigger assembly 13 is fixedly arranged at the end of the skeleton 112 at intervals. It is also within the protection scope of the present utility model to symmetrically arrange two, four or six drum edge trigger assemblies 13 on these six skeletons 112.

[0033] Furthermore, in some embodiments, in the electronic drum trigger assembly of the present utility model, the end of the skeleton 112 includes a first fixed end face 1121 for fixing the trigger bracket 11 on the side wall of the drum barrel. The first fixed end face 1121 is perpendicular to the skeleton 112, and screw holes 1122 for screw fixing to fix the trigger bracket 11 on the side wall of the drum barrel are provided on the first fixed end face 1121. As a more preferred embodiment, the first fixed end face 1121 can be perpendicular to the plane of the trigger bracket 11.

[0034] In the electronic drum trigger assembly of the present utility model, a second fixed end face 1122 for fixing the drum edge trigger assembly 13 is also provided on the end of the skeleton 112 where the drum edge trigger assembly 13 is arranged. In some embodiments, the second fixed end face 1122 is two fixing blocks 1122a located on the upper plane of the skeleton 112 and extending to the left and right sides of the skeleton.

[0035] In the electronic drum trigger assembly of the present utility model, the drum rim trigger assembly 13 includes two isolation and buffer foams 131 located on two fixing blocks 1122a, a drum rim trigger fixing member 132 located on the two isolation and buffer foams 131, and a drum rim trigger device 133 located on the drum rim trigger fixing member 132. The drum rim trigger device 133 includes, from bottom to top, a first adhesive sticker 1331, a drum rim trigger (piezoelectric ceramic sheet) 1332, and a first flexible foam 1333. In some embodiments, the first adhesive sticker 1331 is circular and can be an elastic double-sided adhesive, which serves to paste the drum rim trigger 1332. The drum rim trigger 1332 is circular, and its diameter can be slightly larger than the diameter of the first adhesive sticker 1331. The first flexible foam 1333 is cylindrical, and the diameter of the first flexible foam 1333 is smaller than the diameter of the drum rim trigger 1332 and is in a cylindrical shape. In some embodiments, a light-shielding ring (not shown in the figure) is further provided at a position on the drum rim trigger 1332 that is not covered by the first flexible foam 1333 to shield the light that is not covered by the first flexible foam 1333.

[0036] In the electronic drum trigger assembly of the present utility model, the drum head trigger assembly 12 includes a drum head trigger support member 121 located on a circular support 111 at the central position of a trigger bracket 11, and a drum head trigger device 122 located on the drum head trigger support member 121. The drum head trigger device 122 includes, from bottom to top, a second adhesive sticker 1221, a drum head trigger (piezoelectric ceramic sheet) 1222, and a second flexible foam 1223. In some embodiments, a circular boss 1211 is provided on the drum head trigger support member 121, and the drum head trigger 1222 is disposed on the circular boss 1211.

[0037] As Figure 3 shown, on the reverse side of the electronic drum trigger assembly of the present utility model, a side strike trigger 14 is also pasted on a part of the first fixed end face 1121 of the skeleton 112 where the drum rim trigger assembly is not provided and below the skeleton 112. The side strike trigger 14 can assist in sensing the trigger of side strike knocking. On the ends of at least two of the skeletons 112 and on the lower plane of the skeleton 112, a PCB circuit board 15 is provided. It is within the protection scope of the present utility model to symmetrically arrange two, four, or six PCB circuit boards 15 on the lower planes of these six skeletons 112. The drum head trigger 1222 of the drum head trigger assembly 12 and the drum rim trigger 1332 of the drum rim trigger assembly 13 respectively have wires connected to the PCB circuit board 15.

[0038] The utility model fixes three (or two, or four, or six) drum-edge trigger components 13 at symmetric positions near the inner wall of the drumhead of an electronic drum through a trigger bracket 11, which are used to detect vibration signals from the outer side of the mesh surface to the center of the drumhead and near the inner side of the edge. The drumhead trigger component 12 is arranged at the center position of the trigger bracket 11 and is used to detect vibration signals at the center position of the drumhead. Thus, the drumhead trigger component and the drum-edge trigger components are separately arranged, and the drumhead trigger and three (or two, or four, or six) drum-edge triggers together constitute a three-dimensional multi-point detection drumhead trigger. When the drumstick strikes, the drumhead trigger at the center position compares and analyzes the vibration signals with the three (or two, or four, or six) drum-edge triggers on the side branches, so as to determine the striking position and the strength of the signal, and converts the striking vibration signal into a digital signal and transmits it to the sound source processor. After the discrimination and processing of the sound source processor, it locates according to different positions of striking the drumhead and outputs different tone changes. While having the side-strike trigger function, it also enhances the stability of the side-strike signal, and avoids the phenomenon of signal crosstalk between the drumhead and drum edges at different positions. While improving the sensitivity of the side-strike trigger, it also ensures the uniformity of the side-strike on the drumhead, and is closer to the tone change and sound effect of a traditional drum.

[0039] See Figure 4 , the utility model further provides an electronic drumhead, which includes a drumhead 20, a drum barrel 30, a trigger component 10 and a bottom drumhead 40. A signal output socket 50 is installed on the inner wall of the drum barrel 30. The trigger component 10 is fixed in the drum barrel 30 by locking on the inner side of the drum barrel 30 through a first fixed end face 1121. The PCB circuit board 15 on the trigger component 10 is electrically connected to the socket circuit on the signal output circuit socket 50. The PCB circuit board 15 on the trigger component 10 is electrically connected to the drumhead trigger 1222 and the drum-edge trigger 1332 thereon through wires. Several axially extending drum lugs 31 are symmetrically arranged on the outer side wall of the drum barrel 30. A metal drum hoop 60 and 70 are respectively arranged above the drumhead 20 and below the bottom drumhead 40. The upper metal drum hoop 60 and the drumhead 20 are fixed on the drum lugs 31 of the drum barrel 30 through screws 80. The lower bottom drumhead 20 and the metal drum hoop 70 are fixed on the drum lugs 31 of the drum barrel 30 through screws 90. A drum rubber ring 61 is sleeved on the metal drum hoop 60.

[0040] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
