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 base material layers located at two sidesof 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 innerside part, a second conducting layer arranged on the deformation part and a third conducting layer arranged on the outer side part, and the two ends of the second conducting layer are electrically connected with the first conducting layer and the third conducting layer respectively; both the first conductive layer and the third conductive layer adopt metal foils, the second conductive layer is a conductive adhesive layer formed in a coating or printing mode, the thickness of the conductive adhesive layer is 6-15 [mu] m, and the sheet resistance of the conductive adhesive layer is 10-30 m [omega] / mm < 2 > / mil. One technical effect of the 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 electroacoustic conversion, and more specifically, the present invention relates to a conductive film used for a sound generating device and the sound generating device. Background technique [0002] The sound generating device generally includes a diaphragm and a voice coil combined on one side of the diaphragm, and also includes electrical connectors for electrically connecting the internal circuit and the external circuit of the sound generating device. Among them, the voice coil includes two voice coil lead wires, and the two voice coil lead wires are respectively electrically connected to the two pads of the electrical connector by means of spot welding. Controls the electrical signal in the voice coil. [0003] Generally speaking, the lead wire of the voice coil needs to run out a certain length of thread, and then realize the electrical connection with the electrical connector after being ...
