Sound production device and loudspeaker box thereof

Abstract

The invention provides a sound production device, which comprises a basin stand, a vibration system supported on the basin stand and a magnetic circuit system for driving the vibration system to vibrate and produce sound. The magnetic circuit system has a magnetic gap. The vibration system comprises a diaphragm, an elastic conductive member, a skeleton and a voice coil. The elastic conductive member comprises a first fixing arm connected to the basin stand, a second fixing arm spaced from the first fixing arm, a first elastic arm connecting the first fixing arm and the second fixing arm, and abonding pad extending from the second fixing arm. The framework comprises a framework body supported on the second fixing arm and connected to the vibrating diaphragm and an extension wall formed bybending and extending the framework body, and part of the extension wall extends into the magnetic gap. The voice coil comprises a voice coil body which is fixed on the extension wall and inserted into the magnetic gap and a voice coil lead which bends and extends from the voice coil body to the bonding pad and is electrically connected with the bonding pad. The voice coil lead is attached to theextension wall and extends to the bonding pad along the extension wall. Compared with the prior art, the sound production device and the loudspeaker box are high in reliability.

Description

【Technical field】 [0001] The invention relates to the field of sound and electricity, in particular to a sound generating device used in portable electronic products and a speaker box thereof. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music. Therefore, sound-generating devices for playing sound are widely used in current smart mobile devices. [0003] The sound-generating device in the related art includes a pot frame, a vibration system supported on the pot frame, and a magnetic circuit system that drives the vibration system to vibrate and sound; the vibration system includes a diaphragm, inserted in the magnetic gap The voice coil used to drive the diaphragm to...

AI Technical Summary

Problems solved by technology

[0004] However, in the related art, the voice coil lead wire is often suspended inside the sound-generating device. During the vibration process, the voice coil lead wire is easily damaged or falls off from the elastic conductive member, so that the voice coil cannot be energized and works normally, causing the sound-generating device and the speaker to be damaged. The reliability of the vibration sound of the box is low
