一种超薄减振扬声器及其制造方法
By employing a dual-sided sound-generating structure with both active and passive diaphragms and a damping plate design, the problem of complex and thin existing speaker structures has been solved. This achieves a balance between thinness, lightness, and good damping performance, enhancing sound generation efficiency and low-frequency characteristics.

AI Technical Summary
Existing panel loudspeakers have complex structures, making it difficult to achieve a balance between thinness, light weight, good sealing, and vibration damping performance while ensuring sound production efficiency.
It adopts a double-sided sound-generating structure with active and passive diaphragms. The active diaphragm vibrates through a voice coil, and the passive diaphragm vibrates by the positive and negative pressure difference between the inner and outer sound cavities. The design of damping plates and damping pressure rings achieves the damping effect, while ensuring the airtightness of the speaker and reducing its thickness.
It achieves a thinner and lighter speaker, while improving sound efficiency and vibration damping performance, reducing the thickness by about 30% to 50%, and enhancing low-frequency characteristics and sound effects.
