Sound production device

Abstract

The invention provides a sound production device, which comprises a basin frame, a vibration system supported on the basin frame and a magnetic circuit system with a magnetic gap. The vibration systemcomprises a diaphragm comprising a vibration part, a bending ring part bent and extended from the periphery of the vibration part, and a fixing part bent and extended from the bending ring part and fixed on the basin frame; a framework comprising a flat plate wall and an extension wall, the flat plate wall being attached to the side, close to the magnetic circuit system, of the vibration part andused for serving as a dome structure of the vibrating diaphragm, and the extension wall being bent and extending in the direction away from the vibrating diaphragm from the flat plate wall; and a voice coil, inserted into the magnetic gap and fixedly connected with the extension wall, and the voice coil driving the extension wall to vibrate so as to drive the flat plate wall to vibrate, thereby driving the vibration part to vibrate and produce sound. Compared with the prior art, the sound production device is good in acoustic performance and high in assembly efficiency.

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 pot frame, a vibration system fixed to the pot frame, and a magnetic circuit system with a magnetic gap. The magnetic circuit system drives the vibration system to vibrate and produce sound. The vibration system includes a The frame is used to vibrate and sound the diaphragm, the frame attached to the dome of the diaphragm near the side of the magnetic circuit system, and the voice coil wound around the frame and inserted into the magnetic gap. [0004] However, in the sound-generating devices of the related art, the skeleton is used as a supporting structure to connect the dome ...

Problems solved by technology

[0004] However, in the sound-generating devices of the related art, the skeleton is used as a supporting structure to connect the dome and the voice coil. When assembling, the concentricity between the skeleton and the dome needs to be strictly controlled to ensure the acoustic performance, which makes the assembly efficiency low and even reduces the quality of the finished product.
