Abstract

The invention discloses a passive radiator and sound production equipment, the sound production equipment comprises a shell, and the passive radiator comprises a vibrating diaphragm and an elastic piece. Wherein the vibrating diaphragm comprises a vibrating part and a folding ring part, and the folding ring part is connected to the edge of the vibrating part and is arranged in a surrounding manner along the circumferential direction of the vibrating part; one end of the elastic piece is connected to the vibration part, and the other end of the elastic piece is used for being connected to the shell. According to the technical scheme, the phenomenon that the passive radiator swings and vibrates from the center to the edge can be reduced, so that sound distortion is reduced, and the sound production effect is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of sound-generating devices, in particular to a passive radiator and a sound-generating device using the passive radiator. Background technique [0002] At present, a passive radiator is usually provided in the sound-generating device, so that the passive radiator can passively emit sound under the driving of the speaker in the housing to the air in the housing, so as to realize the adjustment of the bass of the sound-generating device. However, the passive radiator itself lacks a supporting and centering structure when it is driven to vibrate, which makes it prone to rocking vibration from the center of the passive radiator to the edge. The rocking vibration will cause sound distortion and affect the sound production effect. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a passive radiator, which aims to reduce the phenomenon of swing vibration from the c...
