Abstract

The invention discloses a conductive film for a sound production device and the sound production device, the conductive film comprises a conductive layer and a first base material layer and a second base material layer which are located at two sides of the conductive layer, and the conductive film comprises an inner side part, a deformation part and an outer side part; the conducting layer comprises a first conducting layer arranged on the inner side part, a second conducting layer arranged on the deformation part and a third conducting layer arranged on the outer side part, and the first conducting layer, the second conducting layer and the third conducting layer are connected to form at least one conducting circuit; the first conducting layer and the third conducting layer are both madeof metal foils, the Young modulus of the second conducting layer is smaller than that of the metal foils, and the first base material layer is a thermoplastic elastomer layer. One technical effect ofthe invention is that the conductive film has conductivity, can be used as a sound production diaphragm, and can also be used as a support diaphragm.

Description

technical field [0001] The present invention relates to the technical field of electro-acoustic conversion, and more particularly, the present invention relates to a conductive film for a sound-generating device and a sound-generating device. Background technique [0002] The sound-generating device generally includes a vibrating membrane and a voice coil combined on one side of the vibrating membrane, and also includes an electrical connector for electrically connecting the internal circuit and the external circuit of the sound-generating device. The voice coil includes two voice coil leads, and the two voice coil leads are electrically connected to the two pads of the electrical connector by spot welding, etc., and the electrical connector is electrically connected to the external circuit at the same time, so as to pass the electrical signal of the terminal product. Controls the electrical signal in the voice coil. [0003] Generally speaking, the lead wire of the voice c...
