How to make a miniature sounder

Abstract

The invention discloses a micro acoustic generator and a method for manufacturing the micro acoustic generator. The micro acoustic generator comprises a vibrating membrane and a voice coil for driving the vibrating membrane to vibrate to make sounds; the vibrating membrane comprises a ball top and a silica gel folding ring arranged around the ball top; voice coil lead wires are arranged on the voice coil; the micro acoustic generator further comprises flexible circuit boards fixedly supported on the ball top and conductive wires embedded in the silica gel folding ring; the voice coil lead wires are electrically connected with the flexible circuit boards; one end of each conductive wire is electrically connected with the corresponding flexible circuit board and the other ends of the conductive wires are electrically connected with an electric signal input end of the micro acoustic generator so as to realize energization of the voice coil. The micro acoustic generator can save internal additional space-reserving space, and is excellent in performance and high in reliability.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic transducers, in particular to a micro-sounder and a method for making the micro-sounder. 【Background technique】 [0002] Miniature sound generators are widely used in portable electronic devices such as mobile phones, laptop computers, and hearing aids. With the rapid development of these portable electronic devices, people have higher and higher requirements for the miniature sound generators used therein. [0003] The miniature sound generator of the related art includes a diaphragm and a voice coil combined on one side of the diaphragm. When the coil drives the diaphragm to vibrate, it does stretching and bending vibrations. [0004] The inside of the miniature sounder needs to set up additional space for the voice coil lead wire to make way for stretching and bending vibration; during the process of stretching and bending vibration of the voice coil lead wire, the voice coil lead wire is eas...

AI Technical Summary

Problems solved by technology

[0004] The inside of the miniature sounder needs to set up additional space for the voice coil lead wire to make way for stretching and bending vibration; during the process of stretching and bending vibration of the voice coil lead wire, the voice coil lead wire is easy to collide with the diaphragm or pot frame, causing poor pure tone, voice coil The pulling of the lead leads to the unbalanced vibration of the diaphragm and poor acoustic performance; the tensile strength of the voice coil lead for stretching and bending vibration is high and easy to break. In order to avoid the risk of breakage, the voice coil wire can only be selected with high tensile strength. Wire, limiting the improvement of voice coil performance
