Abstract

The invention provides a sound generating device, which includes a basin frame, a vibration system and a magnetic circuit system. The vibration system includes an annular upper diaphragm, a lower diaphragm, a voice coil, an upper skeleton, a lower skeleton and an isolation diaphragm. The diaphragm is fixed to the frame; the lower diaphragm is arranged at intervals around the magnetic circuit system, and the outer peripheral side of the lower diaphragm is fixed to the frame; the upper frame is respectively connected with the upper diaphragm and the voice coil; the lower frame is respectively connected with the lower diaphragm and the voice coil; The outer peripheral side of the isolation diaphragm is connected to the frame body, and the inner peripheral side is connected to the lower frame. Compared with the related art, the sound emitting device of the present invention has higher acoustic loudness and better 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] 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 dome attached to the diaphragm is close to the skeleton on the side of the magnetic circuit system, and the sound is inserted in the magnetic gap and connected with the skeleton to drive the diaphragm to vibrate. lock up. [0003] However, in the sound-generating device of the related art, the vibration system and the magnetic circuit system are stacked up and down, and the structure of the magnetic circuit system is limited in the sound-ge...
