Technical Field

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

[0002] While existing electronic drum products adopt the appearance design of acoustic drums, converting an acoustic drum to an electronic one requires complex structural modifications to the drum body, including drilling holes to install sensors. This process is difficult and costly. Furthermore, the trigger mechanism of the modified bass drum is installed on the drum body, making further modifications or subsequent maintenance inconvenient. Utility Model Content

[0004] The drumhead has a mounting part and can be detachably mounted to the body of the bass drum;

[0005] A triggering mechanism, comprising a triggering surface embedded in the drumhead, wherein a sensor is connected to the side of the triggering surface facing the drum body;

[0006] When an external impact is applied to the trigger surface, the trigger surface transmits the impact to the sensor, which then converts the external impact into an electrical signal.

[0007] Preferably, it also includes a housing, which is fixedly installed on the drumhead, and the triggering mechanisms are all installed inside the housing and connected to the drumhead through the housing.

[0008] Preferably, the triggering mechanism further includes a trigger pad made of a flexible material, which is supported between the triggering surface and the sensor.

[0009] Preferably, the triggering mechanism further includes a support pad made of a flexible material, which is supported between the inner wall of the housing and the sensor.

[0010] Preferably, the triggering mechanism further includes a circuit board, the sensor is fixedly mounted on the circuit board, one side of the circuit board on which the sensor is mounted is connected to the housing through the support pad, and the other side of the circuit board is connected to the triggering surface through the trigger pad.

[0011] Preferably, the trigger pad includes a first trigger pad and a second trigger pad that are attached to each other.

[0024] 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.

[0025] Figure 1 This is a schematic diagram of the overall structure of the bottom drum skin trigger provided in an embodiment of the present invention; Figure 2a and Figure 2b This is a schematic diagram of the triggering mechanism of the bottom drum skin trigger provided in an embodiment of the present invention.

[0026] like Figure 1 , Figure 2a and Figure 2b As shown, this utility model provides a bass drum skin trigger, including a drum skin 1 and a triggering mechanism 2. The drum skin 1 is detachably mounted to the drum body of the bass drum via a mounting part. The triggering mechanism 2 includes a triggering surface 21, which is embedded in the drum skin 1. A sensor 22 is connected to the side of the triggering surface 21 facing the drum body. When an external impact is applied to the triggering surface 21, the triggering surface 21 can transmit the impact to the sensor through its own deformation or vibration. The sensor converts the impact into a corresponding electrical signal, thereby realizing the function of the electric drum.

[0027] By integrating the trigger mechanism required for electronic drums onto the drumhead, when modifying acoustic drums, users only need to install the drumhead equipped with the trigger mechanism onto the original drum body to complete the modification. This reduces the difficulty of modification for users, simplifies the overall structure of the bass drum, and preserves the integrity of the original drum body.

[0028] Among them, such as Figure 1As shown, there are several mounting parts for the drumhead 1, which are spaced apart on the outer periphery of the drumhead 1. The mounting parts are provided with threaded holes for matching with the corresponding mounting holes on the drum body. For the connection between the drumhead 1 and the drum body, other existing installation methods can be adopted according to the actual situation, as long as the detachable connection between the drumhead 1 and the drum body can be met, and the connection strength can be good after the drumhead 1 and the drum body are installed. This will not be elaborated here.

[0029] The trigger surface 21 is embedded in the drum skin 1. The thickness of the trigger surface 21 may be greater than the thickness of the drum skin 1, and the trigger surface 21 may be located inside the drum skin 1 in the radial direction. Alternatively, the thickness of the trigger surface 21 may be less than the thickness of the drum skin 1, and the trigger surface 21 may be completely located inside the drum skin 1. This will not be elaborated here. The trigger surface 21 is preferably made of a flexible material, such as rubber, silicone, or cowhide (leather). Alternatively, it can be made of a multi-layered polyester fiber mesh interwoven with internal foam filling. This allows the trigger surface 21 to undergo instantaneous elastic deformation when an external impact is applied, thereby transmitting the impact to the sensor 22. Furthermore, the elasticity of the trigger surface 21 is closer to that of a traditional drumhead, providing the performer with more realistic physical feedback. Alternatively, the trigger surface 21 can be made of a rigid material, such as composite materials like glass fiber or resin, or even a metal trigger surface, which can significantly extend its lifespan. In this case, a suitable drumstick should be selected to improve the tactile feedback of the trigger surface, and a suitable sensor should be chosen. For example, a strain gauge sensor can be attached to the rigid trigger surface 21 to detect the instantaneous strain of the trigger surface, thereby sensing the external impact and generating a corresponding electrical signal. The specific configuration of the trigger surface 21 is sufficient as long as it can transmit the impact force to the sensor 22 when struck by the drumstick. In actual production applications, a suitable configuration can be selected as needed, which will not be elaborated here.

[0030] Sensor 22 is preferably a piezoelectric sensor, which can convert changes in external pressure into electrical signals. Then, other sensors equipped with the drum can convert the electrical signals into sound signals and emit them. Sensor 22 can also be other sensors that can perform this type of signal conversion, such as the strain gauge sensor mentioned above. The specific type of sensor 22 should be adjusted according to the trigger surface 21 and the actual type of drumstick, which will not be elaborated here.

[0031] Figure 3 This is a schematic diagram of the housing of the bottom drum skin trigger provided in an embodiment of the present invention.

[0032] like Figure 3 As shown, in one preferred embodiment, a housing 3 is also included. The housing 3 is fixedly mounted on the drumhead 1, and the trigger surface 21 and the sensor 22 are both installed inside the housing 3. Figure 1 and Figure 3 As shown, the housing 3 includes an outer shell 31 and a fixing ring 32. The outer shell 31 has a mounting ring 313 and a mounting cavity 314. The mounting ring 313 and the fixing ring 32 have matching mounting holes. The mounting cavity 314 is used to accommodate components such as the trigger surface 21 and the sensor 22. When installing the housing 3 and the drumhead 1, the drumhead 1 has a mounting opening that matches the maximum outer diameter of the mounting cavity 314. The mounting cavity 314 passes through the mounting opening and is located on the inner side of the drumhead 1 (i.e., the side closer to the drum body). The mounting ring 313 abuts against the outer side of the drumhead 1 (i.e., the side away from the drum body and facing the outside of the bottom drum). Then, the inner hole of the fixing ring 32 is fitted onto the outside of the mounting cavity 314, and the mounting holes on the fixing ring 32 and the mounting ring 313 match each other. The annular end faces of the fixing ring 32 and the mounting ring 313 clamp the corresponding part of the drumhead 1, so that the housing 3 is fixedly installed on the drumhead 1.

[0033] The triggering mechanisms 2 are all installed inside the housing 3, and the triggering mechanisms 2 are connected to the drumhead 1 through the housing 3. That is, there is no direct connection between the triggering mechanisms 2 and the drumhead 1. In this way, when an external impact is applied to the triggering surface 21, the triggering surface 21 can effectively transmit the impact to the sensor 22. When the external impact contact point deviates and is applied to the drumhead 1, or when the operator accidentally touches the drumhead 1 (or the drum body), the vibration of the drumhead 1 is transmitted to the triggering mechanism 2 through the housing 3. At this time, the vibration received by the triggering mechanism 2 can be minimized, the occurrence of accidental triggering can be reduced, and the use effect can be improved.

[0034] like Figure 2a and Figure 2b As shown, in one preferred embodiment, the triggering mechanism 2 further includes a trigger pad made of a flexible material, such as sponge, silicone, etc. The trigger pad is supported between the triggering surface 21 and the sensor 22. In this way, the trigger pad can absorb and disperse part of the impact force, preventing it from being directly and completely transmitted to the sensor. Furthermore, the elasticity and compression / rebound characteristics of the trigger pad provide a damping effect, allowing the triggering surface to rebound after being struck, but delaying and weakening the speed and force of its downward rebound, making it insufficient to trigger the sensor again. This allows for more accurate identification of the performer's single strike intention.

[0035] Furthermore, the trigger pads include a first trigger pad 241 and a second trigger pad 242 that are in contact with each other. The first trigger pad 241 and the second trigger pad 242 respectively abut against the trigger surface 21 and the sensor 22. The hardness of the first trigger pad 241 is less than that of the second trigger pad 242. The softness of the first trigger pad 241 allows it to provide a more comfortable hitting feel and improve the performance of the bass drum. The second trigger pad 242 is relatively harder and is supported between the trigger surface 21 (the first trigger pad 241) and the sensor 22. It can provide more stable support for the trigger surface 21 (and the first trigger pad 241). When it is subjected to impact, its deformation is small, which can play a good protective role for the hard material sensor 22.

[0036] The materials of the first trigger pad 241 and the second trigger pad 242 can be selected according to actual cost and other factors, such as open-pore polyurethane. The difference in hardness between the two trigger pads can be achieved by changing parameters such as pore density and material difference on the trigger pads, so that the two trigger pads can achieve the corresponding functions. This will not be elaborated here.

[0037] In one preferred embodiment, the triggering mechanism 2 further includes a support pad 25 made of a flexible material, the specific material of which can be the same as that of the trigger pad. The support pad 25 is supported between the inner wall of the housing 3 and the sensor 22. On the one hand, it can form a buffer between the housing 3 and the sensor 22, avoiding the sensor 22 from being damaged due to the large force generated between the rigid structure of the housing 3 and the sensor 22. On the other hand, when an external impact contact is applied to the drumhead 1 due to deviation, or when the operator accidentally touches the drumhead 1 (or the drum body), the vibration of the drumhead 1 is transmitted to the housing 3. Since there is a buffer between the housing 3 and the sensor 22 through the support pad 25, the support pad 25 can absorb some of the vibration of the housing 3 caused by the accidental touch of the drumhead 1 (or the drum body). Therefore, it can minimize the vibration of the sensor 22 received by the accidental touch, reduce the occurrence of accidental touch, and improve the performance.

[0038] Furthermore, the triggering mechanism 2 also includes a circuit board 23. The sensor 22 is fixedly mounted on the circuit board 23. The side of the circuit board 23 with the sensor 22 mounted is connected to the housing via a support pad 25, and the other side of the circuit board 23 is connected to the trigger surface 21 via a trigger pad. The circuit board 23 can be a hardware circuit board such as a PCB board, which facilitates the installation of the sensor 22 and the transmission of its signal. In addition, the material and overall structure of the circuit board 23 are more stable than the sensor 22. By connecting the circuit board 23 to the trigger surface 21 and the housing 3, and then transmitting the vibration to the sensor 22, the stability and service life of the drum can be improved.

[0039] Furthermore, such as Figure 2a as well as Figure 3As shown, the trigger surface 21, first trigger pad 241, second trigger pad 242, circuit board 23 (sensor 22), and support pad 25 of the trigger mechanism 2 are connected in sequence, and the support pad 25 is fixedly installed on the inner wall of the mounting cavity 314 of the housing 31, so that the trigger mechanism 2 and the housing 3 are connected to the mounting cavity 314 only through the support pad 25, and the trigger mechanism 2 is suspended inside the housing 31 (e.g., Figure 3 As shown, the diameters of the trigger surface 21, trigger pad, circuit board, etc., are all smaller than the inner diameter of the mounting cavity 314, so that the radial outer side of the trigger surface 21 is the gap between it and the mounting cavity 314, while one axial side of the trigger surface 21 is the external space of the bottom drum, and the other side is the support of the trigger pad. The trigger surface 21 as a whole has sufficient deformation and movement margin. When the drumstick strikes the trigger surface 21, the trigger surface 21 can effectively transmit the impact force to the trigger pad, circuit board 23 and sensor 22 on its inner side. At the same time, the trigger pad, circuit board 23 and support pad 25 on the inner side of the trigger surface 21 in the axial direction provide support and buffering, which can effectively absorb the impact suffered by the trigger surface 21 and improve the service life of the trigger surface 21.

[0041] like Figures 4 to 6 As shown, in one preferred embodiment, the mounting cavity 314 of the outer casing 31 is a cylindrical cavity with a bottom surface shape of [insert shape here]. Figure 4 The circle shown has a ring-shaped area on its bottom surface divided into several fan-shaped mounting portions 312 along the circumference of the ring-shaped area, and the support pad 25 is... Figure 5 The fan-shaped annular structure shown has a fan-shaped annular groove in the mounting part 312 that matches the support pad 25 (the groove extends toward the inside of the drum body), so that the support pad 25 can be fixedly installed in the groove of the mounting part 312.

[0042] Furthermore, there can be three support pads 25, and correspondingly, there are also three mounting portions 312 for mounting the support pads. The other parts of the mounting portions 312 have open structures, and the central part of the annular mounting portion 312 also has an open structure (e.g., Figure 6 The back structure of the outer shell 31 shown has three fan-shaped openings and a central circular opening. These openings can serve as weight-reducing holes to reduce the weight of the outer shell 31, thereby reducing the torque on the drumhead 1 at the location of the outer shell 31 outside the drumhead 1 and improving the stability of the bass drum drumhead during use and installation.

[0043] Figure 7 This is a schematic diagram of the interface socket of the bottom drum skin trigger provided in an embodiment of the present invention.

[0044] like Figure 6 and Figure 7 As shown, in one preferred embodiment, an interface socket 4 is provided on the drumhead 1. The interface socket 4 has a first wire port 41 located on the outer side of the drumhead 1 and a second wire port 42 located on the inner side of the drum body. The interface socket 4 is used to guide cables such as wires and signal lines from outside the drum body into the drum body. The opening end face of the first wire port 41 is approximately flush with the outer wall surface of the drumhead 1 for guiding external cables. The second wire port 42 can be as follows: Figure 7 As shown, the external cable extending from the first wire port 41 through the second wire port 42 can be extended and bent more conveniently to the sensor 22 and circuit board 23 inside the housing 31.

[0045] The cable extending into the drum body can enter the interior of the outer casing 31 through the weight-reduction hole provided on the outer casing 31, or it can be provided on the outer casing 31 as described above. Figure 6 The connection port 311 shown is used for cable insertion and installation. A cable clamping structure can also be set on the connection port 311. After the cable is connected to the sensor 22 and the circuit board 23, the cable clamping structure can fix the cable to the housing 31, thereby improving the stability of the bottom drum cable connection. The specific structure of the connection port 311 and the cable clamping structure can be selected from existing solutions according to the actual situation, which will not be elaborated here.

[0046] In summary, by applying the kick drum trigger provided in this embodiment, the trigger mechanism 2 is installed and connected to the drumhead 1 through the housing 3, and the electrical components inside the drum body are connected to the cable through the interface socket 4, so that all the components required for the kick drum are integrated on the drumhead 1. When modifying the kick drum, it is only necessary to install the drumhead 1 on the kick drum to start using it. Furthermore, through the trigger pad, support pad, etc. of the trigger mechanism 2, the accidental activation of the kick drum can be effectively reduced, and the usage effect can be improved.

[0047] 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.
