Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to an anti-vibration membrane structure. Background Art

[0002] A diaphragm is a thin film element that vibrates and converts mechanical energy into electrical energy, or vice versa. In speakers and headphones, it's a key component that converts electrical signals into sound. The diaphragm vibrates, converting electrical signals into sound waves, allowing us to hear. Its vibration characteristics determine the quality of the sound and the pitch of the timbre.

[0003] Patent document CN220108185U discloses a diaphragm structure of a micro-speaker, comprising a speaker body, a lining provided inside the speaker body, a permanent magnet fixedly connected inside the speaker body, a vibrating diaphragm further provided on the speaker body, and a blowing assembly and a dust removal assembly used in conjunction with each other provided on the speaker body, the blowing assembly being arranged between the lining and the permanent magnet, and the dust removal assembly being arranged on the vibrating diaphragm. The diaphragm structure of the micro-speaker proposed in the present utility model is provided with an air blowing assembly and a dust removal assembly. Under the cooperation of the air blowing assembly and the dust removal assembly, as the speaker is running, a number of air jet holes can continuously spray gas toward the vibrating diaphragm, thereby cleaning the vibrating diaphragm and preventing dust attached to the vibrating diaphragm from affecting the sound effect of the speaker. The user does not need to manually clean the dust on the vibrating diaphragm, thereby improving the practicality of the speaker.

[0004] In the above scheme, the vibration diaphragm is a traditional diaphragm, the bottom neck of which is bald, and its cross-section is a narrow ring, which is not convenient for connection and easily delaminated with glue. At the same time, traditional diaphragms are usually formed by heating a plastic sheet of fixed thickness through a mold blow molding. The larger the size of the diaphragm, the thinner the edge and the lower the structural strength. Especially in winter, it is easy to break when the speaker power is high. Therefore, it is necessary to provide an anti-detachment diaphragm structure to solve the shortcomings of the existing technology. Utility Model Content

The glue on the upper and lower sides of the diaphragm can penetrate each other through the adhesive holes, gluing the main body and the support voice coil together to improve the bonding strength. A reinforcing rib 1 8 is provided on the front side of the main body, and a reinforcing rib 2 9 is provided on the back side of the annular fold. The reinforcing rib 1 and the reinforcing rib 2 can improve the structural strength of the main body and the annular fold to prevent the diaphragm body from breaking during vibration.

[0026] In this embodiment, the main body, annular folds, and hanging edge are further configured as a single unit, with the main body, annular folds, and hanging edge having the same axis and increasing diameters. This single unit can reduce manufacturing costs and improve product consistency and yield.

[0027] In this embodiment, it is further configured that a limiting groove 10 is provided on the outer circumference of the suspension edge, and the bolt passes through the limiting groove and is connected to the basin frame. The basin frame is not drawn in the figure. The limiting groove plays a limiting role to prevent the diaphragm body from moving and improve the stability of the diaphragm body. The size of the basin frame directly affects the number of limiting grooves. The larger the size of the basin frame, the more limiting grooves are opened.

[0028] In this embodiment, it is further configured that the reinforcing ribs 1 and 2 are arranged in a ring array with the same axis. The larger the size of the diaphragm body, the more reinforcing ribs 1 and 2 are arranged.

[0029] In this embodiment, air holes 11 are further provided between adjacent reinforcing ribs. The air holes can facilitate the output of sound waves and the balance of air flow, thereby improving the efficiency of the speaker and increasing the sense of bass volume.

[0030] In this embodiment, it is further configured that the back of the dust cap is adhered to the front of the main body and covers the middle hole. The dust cap is not drawn in the figure. The dust cap plays the role of dust protection and reinforcement of high pitch.
