Problems solved by technology

[0004] However, in the sounding device of the related art, the lower end of the voice coil is prone to swing during the vibration process, which affects the acoustic performance. At the same time, because the voice coil itself participates in the vibration, the voice coil wire has the risk of vibration disconnection, which affects the reliability of the sounding device.

Abstract

The invention provides a sound production device. The sound production device comprises a cone stand, and a vibration system and a voice coil assembly which are respectively fixed on the cone stand. The vibration system comprises a vibrating diaphragm fixed on the cone stand, a magnetic assembly which drives the vibrating diaphragm to vibrate and produce sound and is provided with a magnetic gap,and an auxiliary vibrating diaphragm which is arranged opposite to the vibrating diaphragm at an interval and elastically supports the magnetic assembly. The voice coil assembly is fixed at the side,far away from the vibrating diaphragm, of the cone stand, and at least part of the voice coil assembly is inserted into the magnetic gap. Compared with the prior art, the sound production device is simple in structure, good in reliability and excellent in acoustic performance.

Description

【Technical field】 [0001] The invention relates to the field of electroacoustic conversion, in particular to a sound generating device used in electronic sound box products. 【Background technique】 [0002] Sound generating devices, also known as loudspeakers or horns, are used in speakers to convert audio signals into sound playback. [0003] The sound-generating device in the related art includes a basin frame, a vibration system fixed to the basin frame and a magnetic circuit system with a magnetic gap, the magnetic circuit system drives the vibration system to vibrate and sound, and the vibration system includes The diaphragm of the basin frame and the voice coil fixed to the diaphragm and inserted into the magnetic gap to drive the diaphragm to vibrate and produce sound. [0004] However, in the sounding device of the related art, the lower end of the voice coil is prone to swing during the vibration process, which affects the acoustic performance. At the same time, beca...
