Loudspeaker with FPC (flexible printed circuit) and bonding pad integrally formed and assembly method of loudspeaker

Abstract

The invention relates to a loudspeaker with an FPC and a bonding pad integrally formed and an assembling method thereof. The loudspeaker comprises a lower shell, a vibrating diaphragm, a magnetic circuit system, a voice coil and the FPC. The vibrating diaphragm and the lower shell form a corresponding sound cavity, and the FPC is arranged in the sound cavity; the FPC and the bonding pad are integrally formed, the FPC is electrically connected with the bonding pad, the lower shell is provided with a bonding pad placement position, and the bonding pad is led out from the interior of the sound cavity and is fixedly arranged at the bonding pad placement position; and the voice coil is electrically connected to the FPC through a voice coil lead led out of the voice coil. According to the loudspeaker, the structure of a traditional loudspeaker is changed, the FPC is arranged between the vibrating diaphragm and the lower shell, the voice coil and the voice coil lead are vibrated along with the vibrating diaphragm and the FPC, and the problems of fatigue, breakage and the like of the voice coil lead are solved.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a loudspeaker in which an FPC and a solder pad are integrally formed and an assembly method thereof. Background technique [0002] A speaker is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great influence on the sound quality. The speaker is the weakest component in the audio equipment, and it is the most important component for the sound effect; in portable electronic equipment such as portable mobile communication terminal equipment, notebook computers, MP3 players, etc. A speaker module that converts electrical signals into audio signals. [0003] In the existing loudspeaker, the voice coil vibrates with the diaphragm, and the voice coil lead from the voice coil needs to be connected to the FPC or the pad. Therefore, one end of the voice coil lead vibrates and the other end does not vibrate, which makes the voice ...

AI Technical Summary

Problems solved by technology

[0003] In the existing speakers, the voice coil vibrates with the diaphragm, and the voice coil leads from the voice coil need to be connected to the FPC or pad, so one end of the voice coil lead vibrates and the other end does not vibrate, causing the voice coil lead to be easily damaged during the working process of the speaker. fatigue, fracture
