| titleOfInvention | Sound membrane structure |
| abstract | The invention relates to a sound membrane structure, the sound membrane structure is placed in a sound-producing device, and the sound-producing device includes a frame, a sound membrane structure and a suspended edge that are set in the frame, the inner periphery of the suspended edge connects with the sound membrane structure, and the outer periphery of the suspended edge connects with the frame, wherein the sound membrane structure includes a vibrating diaphragm body and a composite material layer, the composite material layer is combined on the surface of the vibrating diaphragm body or absorbed in the vibrating diaphragm body, the composite material layer is composed of one or more than one tetrapyrrole compounds and one or more than one metal ions, in addition, the thickness of the composite material layer is smaller than that of the vibrating diaphragm body, the sound membrane structure is placed in the sound-producing device for use as a loudspeaker. The sound membrane structure provided by the invention achieves the effect of modifying the sound quality of sound by combining the tetrapyrrole compound and the metal ions on the surface. |
