Abstract

The invention provides a sound production device, which comprises a basin stand with an accommodating space, a vibration system accommodated in the accommodating space and a magnetic circuit system for driving the vibration system to vibrate and produce sound; the magnetic circuit system comprises a magnet yoke fixed on the basin stand; the vibration system comprises a first vibrating diaphragm for dividing the accommodating space into a front cavity and a rear cavity; the sound production device also comprises a dust cover which connects the basin frame and the magnet yoke. The dustproof cover divides the rear cavity into a first rear cavity close to the first vibrating diaphragm and a second rear cavity far away from the first vibrating diaphragm; the dustproof cover comprises a first fixing part fixedly connected with the basin stand, a second fixing part for fixing the magnet yoke, and a connecting part for connecting the first fixing part and the second fixing part. The connectingpart protrudes and extends towards the direction of the first vibrating diaphragm to form a protruding part. The dustproof cover of the sound production device can increase the volume of the rear cavity and increase the filling volume of the sound absorption particles.

Description

【Technical field】 [0001] The invention relates to the field of electronic products, in particular to a sound-generating device. 【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.
