Description

Technical Field

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

[0002] The timbre when a traditional drum is struck on the edge of the mesh head is quite different from that when it is struck on the central surface 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] Most of the existing electronic drum heads on the market at present use a single piezoelectric ceramic sheet (sensor) to sense the percussion signal. In order to achieve both the drum head percussion function and the rimshot function, some electronic drums install a piezoelectric ceramic sheet (sensor) for the drum rim on one side of the inner wall of the drum cavity. In this way, when striking, 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 striking the drum head, due to the different magnitudes of the electrical signals generated by strikes at different positions, it will lead to uneven signal conduction. Especially when striking across the rimshot, the signal is unstable, sometimes present and sometimes absent, 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 head trigger device 5 is provided on the circular ring protrusion 41. A trigger device for the drum rim is provided in the concave part 42 at the center of the circular ring protrusion 41. When striking 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 rimshot can be received well, and the triggering of the drum rim is more uniform.

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

[0033] To this end, the following solutions are proposed:

[0034] See also Figure 1 、 Figure 2 As shown, the present invention provides an electronic drum rim trigger assembly 10, which is located in the drum disc of the electronic drum, wherein the drum disc includes a drum barrel and a drum surface. The electronic drum rim trigger assembly 10 includes a suspension bracket 11 and a drum rim trigger (piezoelectric ceramic piece) 12 located on the suspension bracket 11. The suspension bracket 11 includes a vibrating member 111 and a plurality of suspension fixing members 112. The vibrating member 111 is arranged parallel to the drum surface of the drum disc and extends radially divergently with the center position of the drum disc as the center. The suspension fixing members 112 are located at the edge of the vibrating member 111 and are used to suspend the vibrating member 111 on the inner wall of the drum barrel of the drum disc. The drum rim trigger 12 is arranged at the center position of the vibrating member 111. During actual use, the top of the suspension fixing 112 of the suspension bracket 11 of the electronic drum rim trigger assembly 10 is suspended on the inner wall and top edge of the drum barrel of the electronic drum drum, and contacts the edge of the drum head located on the drum barrel. Therefore, when the drum stick hits a position near the inner side of the edge of the drum disk, the vibration of the suspension fixing 112 of the suspension bracket 11 of the drum rim trigger assembly 10 is transmitted to the vibrating member 111, and finally transmitted to the drum rim trigger 12 located at the center position of the vibrating member 111, and the drum rim trigger 12 senses the vibration signal.

[0035] As a preferred embodiment of the present invention, in the electronic drum rim trigger assembly 10 of the present invention, the vibrating member 111 includes a circular bracket 1111 located at the center of the drum plate and a plurality of skeletons 1112 that are radially extended from the circular bracket 1111, are evenly distributed around the circumference, and have the same length. The suspension fixing member 112 is fixed to the extended end of the skeleton 1112. In some embodiments, as Figure 1 and Figure 2As shown, the vibrating member 111 is in the shape of a disc, with six uniformly circumferentially distributed skeletons 1112 provided thereon. On these six skeletons 1112, six suspension fixing members 112 are provided at the extending ends of the six skeletons 1112. In addition, symmetrically arranging three, four, five, eight or the like skeletons 1112 is also within the protection scope of the present utility model.

[0036] Furthermore, in some embodiments, in combination with Figure 3 As shown, the suspension fixing member 112 includes a fixing portion 1121 and a suspension portion 1122.

[0037] Specifically, the fixing portion 1121 is used to fix the suspension fixing member 112 to the extending end of the skeleton 1112. In some embodiments, there is a screw hole 1121a on the fixing portion 1112, and the suspension fixing member 112 is fixed to the extending end of the skeleton 1112 through a screw 113 and a nut 114. Other fixing methods, such as gluing, welding and the like, are also within the protection scope of the present utility model.

[0038] Furthermore, the suspension portion 1122 includes a hook 1122a for hooking on the inner wall of the drum barrel and a connecting portion 1122b connecting the hook 1122a and the fixing portion 1112. The lengths of the connecting portions 1122b of the suspension fixing members 112 on each skeleton 1112 are the same.

[0039] As a preferred embodiment of the present utility model, in the electronic drum rim trigger assembly 10 of the present utility model, the drum rim trigger 12 is arranged at the central position of the vibrating member 111 of the suspension bracket 11, and is pasted on the lower plane of the suspension bracket 11 and located on the circular bracket 1111 through a sponge 13.

[0040] In some embodiments, as Figure 1 、 Figure 2 shown, the circular bracket 1111 includes an outer circular support frame 1111a, an inner circular support frame 1111b, and several radially extending and circumferentially uniformly distributed ribs 1111c located between the outer circular support frame 1111a and the inner circular support frame 1111b. The drum rim trigger 12 is a piezoelectric ceramic disc, and its diameter should be greater than the diameter of the inner circular support frame 1111b and less than the diameter of the outer circular support frame 1111a.

[0041] During actual use, when the drumstick strikes a position near the inner side of the edge of the drumhead, the vibration of the suspension fixing member 112 of the suspension bracket 11 of the rim trigger assembly 10 is transmitted to the vibrating member 111, and finally transmitted to the circular bracket 1111 located on the vibrating member 111. The vibration is then transmitted to the rim trigger 12 through the outer circular support frame 1111a and the rib 1111c of the circular bracket 1111, and the rim trigger 12 senses the vibration signal.

[0042] See Figure 6 , the present utility model further provides an electronic drumhead, which includes a drumhead 20, a drum barrel 30, a rim trigger assembly 10, and a bottom drumhead 40. The suspension fixing member 112 of the suspension bracket 11 of the rim trigger assembly 10 is suspended on the inner wall of the drum barrel 30, and its top contacts the edge of the drumhead.

[0043] In the electronic drumhead of the present utility model, a drumhead trigger unit 50 is further included. The drumhead trigger unit 50 is fixed on the inner wall of the drum barrel 30. In some embodiments, the drumhead trigger unit 50 is fixed, for example, at a position between the extended ends of the two skeletons 1112 of the suspension bracket 11 of the rim trigger assembly 10.

[0044] Specifically, as Figure 4 , Figure 5 shown, the drumhead trigger unit 50 includes a fixing bracket 501 and a drumhead trigger assembly 502 located on the fixing bracket 501. In some embodiments, the fixing bracket 501 includes a first fixing end face 5011 for fixing the drumhead trigger unit 502 on the inner wall of the drum barrel 30 and a second fixing end face 5012 for fixing the drumhead trigger assembly 502.

[0045] As a preferred embodiment of the present utility model, the first fixing end face 5011 is perpendicular to the drumhead 20 of the electronic drumhead, and screw holes 5011a for screw fixation are provided on the first fixing end face 5011. Other fixing methods, such as gluing, welding, etc., are also within the protection scope of the present utility model.

[0046] As a preferred embodiment of the present utility model, the second fixing end face 5012 is parallel to the drumhead 20 of the electronic drumhead and is two fixing blocks 5012a extending horizontally to both sides.

[0047] In the electronic drum pad of the present utility model, the drum surface trigger assembly 502 includes two isolation buffer foams 5021 located between two fixing blocks 5012a, a drum surface trigger fixing member 5022 located on these two isolation buffer foams 5021, and a drum surface trigger device 5023 located on the drum surface trigger fixing member 5022. In some embodiments, the drum surface trigger device 5023 sequentially includes an adhesive patch 5023a, a drum surface trigger 5023b, and a flexible foam 5023c from bottom to top. In some embodiments, the adhesive patch 5023a is circular and can be an elastic double-sided adhesive, which serves to paste the drum surface trigger 5023b. The drum surface trigger 5023b is circular, and its diameter can be slightly larger than the diameter of the adhesive patch 5023a. The flexible foam 5023c is cylindrical, and the diameter of the flexible foam 5023c is smaller than the diameter of the drum surface trigger 5023b and is in a cylindrical shape. In some embodiments, a light-shielding ring 5023d is further provided at a position on the drum surface trigger 5023b that is not covered by the flexible foam 5023c to shield the light that is not covered by the flexible foam 5023c. As a preferred implementation manner, the drum surface trigger unit 50 is fixed on the inner wall of the drum barrel 30, for example, fixed at a position between the extending ends of two skeletons 1112 of the hanging bracket 11 of the drum edge trigger assembly 10. At the same time, the drum surface trigger unit 50 is preferably fixed at a position where the flexible foam 5023c of the drum surface trigger unit 50 is close to the drum surface 20.

[0048] Furthermore, the fixing bracket 501 of the drum surface trigger unit 50 further includes a PCB circuit board fixing end face 5013 located on a horizontal plane opposite to the first fixing end face 5011. A PCB circuit board 60 is fixedly installed on the PCB circuit board fixing end face 5013. Moreover, the drum surface trigger 5023b of the drum surface trigger unit 50 and the drum edge trigger 12 of the drum edge trigger assembly 10 respectively have wires connected to the PCB circuit board 60.

[0049] In the electronic drum pad of the present utility model, a signal output socket 70 is further installed on the inner wall of the drum barrel 30. The rim trigger assembly 10 is suspended on the inner wall and the top edge of the drum barrel of the electronic drum pad through the suspension fixing member 112 of its suspension bracket 11. The PCB circuit board 60 on the drum head trigger unit 50 is circuit-connected to the plug-in seat on the signal output circuit socket 70. The PCB circuit board 60 on the drum head trigger unit 50 is electrically connected to the drum head trigger 5023b of the drum head trigger unit 50 thereon and the rim trigger 12 of the rim trigger assembly 10 through wires. The drum head 20 is located on the drum barrel 30. Several axially extending drum lugs 31 are symmetrically arranged on the outer side wall of the drum barrel 30. A metal drum hoop 80 and a metal drum hoop 90 are respectively arranged above the drum head 20 and below the bottom drum head 40. The upper metal drum hoop 80 and the drum head 20 are fixed to the drum lugs 31 of the drum barrel 30 by screws 100. The bottom drum head 20 and the metal drum hoop 90 are fixed to the drum lugs 31 of the drum barrel 30 by screws 110. Finally, a drum rubber ring 81 is sleeved on the metal drum hoop 80.

[0050] As a preferred implementation manner, after the drum head 20 is covered on the drum barrel 30, the drum head 20 is located in the circular groove at the top of the drum barrel 30. The side surface of the top of the hook 1122a of the suspension fixing member 112 contacts the edge of the drum head 20 located on the drum barrel 30. Subsequently, the metal drum hoop 80 is covered on the drum head 20, and the top of the hook 1122a of the suspension fixing member 112 contacts the lower surface of the metal drum hoop 80. In order to ensure good vibration transmission and trigger signal conduction between the suspension bracket 11 of the rim trigger assembly 10 and the drum barrel 30, it is necessary to use, for example, double-sided tape to tightly fit and fix the top and side surface of the hook 1122a of the suspension fixing member 112 to the edge of the drum head 20 and the metal drum hoop 80.

[0051] In the present utility model, the rim trigger assembly 10 is suspended in the drum barrel 30 of the electronic drum pad. The hook 1122a of the suspension bracket 11 of the rim trigger assembly 10 is suspended on the inner wall and the top edge of the drum barrel 30 and contacts the edge of the drumhead 20 located on the drum barrel 30. When the drumstick strikes a position near the inner side of the edge of the drum pad, through the vibration of the suspension fixing member 112 of the suspension bracket 11 of the rim trigger assembly 10, it is transmitted to the vibrating member 111 and finally transmitted to the rim trigger 12 located at the central position of the vibrating member 111. The rim trigger 12 senses the vibration signal of the edge strike. At the same time, the drumhead trigger unit 50 fixed on the inner wall of the drum barrel 30 is used to detect the vibration signal at the central position of the drumhead, so that the drumhead trigger assembly and the rim trigger assembly are separately arranged. The drumhead trigger and the rim trigger together constitute a multi-point detection drumhead trigger. When the drumstick strikes, the drumhead trigger located on it compares and analyzes the vibration signal with the rim trigger, so as to determine the position of the strike and the strength of the signal, and converts the strike 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 is positioned according to different positions of striking the drum pad and outputs different tone changes. While having the edge strike trigger function, it also enhances the stability of the edge strike signal and avoids the phenomenon of signal crosstalk between the drumhead and the drum edges at different positions. While improving the sensitivity of the edge strike trigger, it also ensures the uniformity of the edge strike of the drum pad, and is closer to the tone change and sound effect of the traditional drum.

[0052] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
