Title:
ACOUSTIC GENERATOR
Document Type and Number:
WIPO Patent Application WO/2013/107071
Kind Code:
A1
Abstract:
Disclosed is an acoustic generator. The acoustic generator comprises a vibrating system which comprises a vibrating diaphragm and a voice coil cylinder. One end of the voice coil cylinder is fixedly combined with the vibrating diaphragm and is used as the leading-out end of a leading wire of the voice coil cylinder; a reinforced part is arranged in the position on the vibrating diaphragm, which corresponds to the leading-out of the leading wire; the leading-out end of the leading wire is positioned underneath the reinforced part; and the reinforced part extends in the along-wire direction of the leading wire. In the design of the present invention, because the reinforced part is arranged above the leading-out position of the leading wire, and the reinforced part extends towards the along-wire direction of the leading wire, the leading wire is prevented from bending with the vibration of the vibrating diaphragm when the leading wire vibrates, thereby making the leading wire vibrate in parallel with the reinforced part, preventing the leading wire from generating the defects of wire bending and breaking, poor electric conductivity, etc. in the working process of the acoustic generator, and ensuring the reliability of the acoustic generator.
