Abstract

The invention provides a sound production device, which comprises a basin frame, a vibration system and a magnetic circuit system. The vibration system comprises an annular upper vibrating diaphragm,an annular lower vibrating diaphragm, an annular voice coil, an annular upper framework, an annular lower framework and an annular isolation vibrating diaphragm, and the upper vibrating diaphragm is fixed on the basin frame. The lower vibrating diaphragms are arranged around the magnetic circuit system at intervals, and the peripheral sides of the lower vibrating diaphragms are fixed on the basinframe. The upper framework is respectively connected with the upper vibrating diaphragm and the voice coil. The lower framework is respectively connected with the lower vibrating diaphragm and the voice coil. The outer peripheral side of the isolation diaphragm is connected with the basin stand body, and the inner peripheral side is connected with the lower skeleton. Compared with the prior art, the sound production device is higher in acoustic loudness and better 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] 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...
