[0002] Currently, loudspeakers are widely used in devices such as televisions, computers, and mobile phones. The diaphragm is the main sound-producing component in a loudspeaker, and the quality of the diaphragm directly affects the performance characteristics of the loudspeaker. A common diaphragm consists of a body and a suspension edge. The common material for the body is paper, and the common material for the suspension edge is rubber. The suspension edge is located on the outside of the body, and the body and suspension edge are bonded together to form a complete diaphragm. The prior art 200920154030.2 discloses a speaker drum paper, including a drum paper suspension edge and a drum paper cone with tea particles added to its internal gap, the drum paper cone and the drum paper suspension edge are pasted and connected vertically. Existing paper drums have a single type of body. In actual use, the single type of paper body is prone to cracking, resulting in a short service life. At the same time, the paper body has poor airtightness, unstable sound quality, and reduced overall performance. Therefore, this utility model proposes a composite paper drum structure. Summary of the Invention

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention features a paper body, a lower aluminum body, and an upper aluminum body, each of which can be fixedly bonded to the inner groove of the suspension edge via their corresponding adhesive edges. The adhesive edges work in conjunction with the inner groove for an embedded installation, effectively improving the embedded bonding effect between the layers of the body. By increasing the adhesive contact area between the body and the suspension edge, the connection strength and stability between the body and the suspension edge are effectively enhanced. This results in a superior embedded structure with improved stability and connection strength, preventing body detachment and extending the overall service life. Furthermore, the body assembly of this utility model is respectively provided with a paper body, a lower aluminum body, and an upper aluminum body. The paper body, the lower aluminum body, and the upper aluminum body can be combined to form a complete body structure.
