Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1.

[0039] See also Figures 1 to 8 A drum disc provided by an embodiment of the present invention includes: a pressure ring assembly 100, a mesh assembly 200 and a base 300.

[0040] In this embodiment, please refer to Figures 1 to 4The pressing ring assembly 100 includes a plastic part 110 and a soft rubber part 120. The soft rubber part 120 is filled on the plastic part 110 through an injection molding process. The plastic part 110 is provided with a hollow part 130 for a user to hit the striking part 211. The soft rubber part 120 is arranged on the outer side 140 of the hollow part 130. Specifically, the plastic part 110 is made by an injection molding process. The plastic part 110 is an annular structure with a hollow part 130. The soft rubber part 120 is a soft rubber material. The outer side of the plastic part 110 is formed by a two-color injection molding production process of an injection molding machine. Soft rubber is filled on the outer portion 140 to form a soft rubber part 120. The soft rubber part 120 is mainly used to prevent the user from accidentally touching the outer portion 140 and making abnormal noise when hitting the drum head with a drumstick. The soft rubber part 120 is filled on the plastic part 110 through the injection molding process, so that the pressure ring assembly 100 becomes an integrated structure. In the subsequent assembly, the process and time of assembling the soft rubber part 120 are omitted, and the original complex manufacturing process of multiple parts is integrated into injection molding, which effectively reduces the difficulty and overall cost of the drum plate manufacturing process and improves quality assurance.

[0041] Preferably, see Figure 4 , Figure 5 and Figure 8 The plastic part 110 is provided with a protrusion 150, and the soft rubber part 120 wraps the protrusion 150. The provision of the protrusion 150 increases the contact area between the soft rubber part 120 and the plastic part 110. When the soft rubber part 120 is filled on the plastic part 110 through the injection molding process, the soft rubber part 120 and the plastic part 110 are connected more firmly.

[0042] Preferably, see Figures 1 to 3 The soft rubber part 120 is a ring-shaped structure. Specifically, the soft rubber part 120 layer of the ring-shaped structure covers the outer part 140 of the hollow part 130, thereby preventing the user from accidentally touching the outer part 140 and making abnormal noise when hitting the drum head with a drumstick.

[0043] In this embodiment, please refer to 1. Figure 4 , Figure 5 and Figure 8 The mesh assembly 200 includes a mesh 210 and an outer frame 220. The outer frame 220 frames the mesh 210 and is fixedly connected to the mesh 210. The mesh 210 is a retractable membrane. Specifically, the mesh 210 is made of nylon material, and the outer frame 220 is made of metal material. Figure 2 and Figure 5 The mesh assembly 200 is provided with a striking portion 211 for a user to strike, and a fixing portion for fixing the mesh 210 is provided on the outer peripheral side of the striking portion 211. The outer frame 220 is fixedly connected to the fixing portion so as to fix the mesh to the outer frame 220. The middle portion of the outer frame 220 is hollow, and the striking portion 211 of the mesh 210 is exposed from the hollow position of the outer frame 220.

[0044] In this embodiment, please refer to Figure 1 , Figure 4 , Figure 5 and Figure 8 The base 300 is provided with a bearing portion 310, and the pressing ring assembly 100 fixes the mesh assembly 200 on the bearing portion 310. Specifically, the bearing portion 310 can be a raised columnar structure, and the pressing ring assembly 100 can clamp the mesh 210 or the outer frame 220 on the bearing portion 310, thereby achieving the effect of fixing the pressing ring assembly 100. For example, the pressing ring assembly 100 is bolted to the base 300, and the mesh assembly 200 is clamped between the pressing ring assembly 100 and the base 300. After the pressing ring assembly 100 is fixed to the base 300 by bolts, the pressing ring assembly 100 and the base 300 are relatively fixed, the mesh assembly 200 is framed between the pressing ring assembly 100 and the bearing portion 310, and the mesh assembly 200 is also fixed. During the later production and assembly, only the pressing ring assembly 100 and the base 300 need to clamp the mesh assembly 200, and there is no need to additionally install the soft rubber part 120, and there is no need to fix the mesh 210 to the base 300 by glue or screws, which effectively improves the efficiency of the later production and assembly.

[0045] Example 2.

[0046] The difference between this embodiment and embodiment 1 is that, see Figures 5 to 8 The soft rubber part 120 is composed of a first part 121 and a second part 122. The first part 121 is a side-hitting part, and the second part 122 is a buffer part. A membrane switch 1210 is provided at the bottom of the first part 121. In some specific cases, such as a snare drum, a side-hitting function is required. At this time, the soft rubber part 120 is divided into the first part 121 and the second part 122. The first part 121 is used to realize the side-hitting function. Specifically, a membrane switch 1210 can be provided at the bottom of the first part 121. When a user taps the first part 121, the membrane switch 1210 is triggered. 10, to achieve the side-hitting function, the second part 122 is the buffer part, the buffer part is mainly used to prevent the user from accidentally touching the outer part 140 and making abnormal noise when hitting the drum head with the drumstick. It can be understood that the membrane switch 1210 is also called a light-touch keyboard. It adopts an overall sealed structure composed of a flat multi-layer combination. It is a new type of electronic component that integrates light, machinery and electricity by sealing a key switch, a panel, a mark, a symbol display and a lining plate together. It is a fundamental change in the appearance structure of electronic products. It can replace the keys of conventional discrete components and more reliably perform the tasks of the operating system.

[0047] Preferably, the color of the first part 121 is different from the color of the second part 122. The first part 121 and the second part 122 of different colors are different in color, which facilitates the user to distinguish the first part 121 from the second part 122. The other structures and working principles of this embodiment are the same as those of embodiment 1 and will not be described here.

[0048] An embodiment of the present invention further provides a percussion instrument, including a drum plate as in the aforementioned embodiment. The various variations and specific embodiments in the aforementioned embodiment are also applicable to a percussion instrument in this embodiment. Through the aforementioned detailed description of a drum plate, those skilled in the art can clearly know the implementation method of a percussion instrument in this embodiment. For the sake of brevity of the specification, it will not be described in detail here.

[0049] An embodiment of the present invention further provides a method for manufacturing a drum plate. Based on the drum plate of any one of the above-mentioned embodiments, the manufacturing method specifically includes:

[0050] The soft plastic part 120 is filled on the plastic part 110 by injection molding process, so as to form the pressing ring assembly 100;

[0051] Place the mesh assembly 200 on the supporting portion 310 of the base 300;

[0052] The mesh surface assembly 200 is pressed by the pressing ring assembly 100 , and then the pressing ring assembly 100 is fixedly connected to the base 300 .

[0053] By filling the soft rubber part 120 on the plastic part 110 through the injection molding process, the pressure ring assembly 100 becomes an integrated structure, and the process and time of assembling the soft rubber part 120 are omitted in the subsequent assembly, and the original complex manufacturing process of multiple parts is integrated into injection molding, which effectively reduces the difficulty and overall cost of the drum plate manufacturing process and improves quality assurance. During the later production and assembly, only the pressure ring assembly 100 and the base 300 need to clamp the mesh assembly 200, and there is no need to install the soft rubber part 120 additionally, and there is no need to fix the mesh 210 to the base 300 with glue or screws, which effectively improves the efficiency of later production and assembly.

[0054] Preferably, when filling the plastic part 110 with soft glue by injection molding, the following steps are also included:

[0055] The soft plastic part 120 forms a ring structure with an opening;

[0056] Install a membrane switch 1210 at the position of the plastic part 110 corresponding to the opening;

[0057] A soft rubber strip is installed at the opening, and the soft rubber piece 120 and the soft rubber strip form a closed ring structure.

[0058] Specifically, when the pressure ring assembly 100 is produced, an annular structure with an opening is formed on the plastic part 110 through an injection molding process. The remaining opening position is mainly for realizing the side-clicking function. The membrane switch 1210 is installed at the position of the plastic part 110 corresponding to the opening, and then a soft rubber strip is installed at the opening. The soft rubber strip can be glued to the opening position by glue. When the user needs to side-click, the position of the soft rubber strip can be tapped to trigger the membrane switch 1210, thereby realizing the side-clicking function. The soft rubber part 120 and the soft rubber strip form a closed annular structure, making the structure more complete and beautiful.
