Abstract

The invention belongs to the technical field of sound boxes, and particularly relates to a passive radiator sound box. A passive radiator sound box comprises a box body and further comprises more than one passive radiator, the more than one passive radiator is located on the surface of the box body, each passive radiator comprises a body, a first shell, a second shell, an upper damper and a lower damper, the upper damper and the lower damper are coaxially arranged on the first shell in a sleeved mode, the top face of the first shell is fixedly connected with the body, and the top face of the second shell is fixedly connected with the body. The upper damper is provided with a first inner circumferential surface and a first outer circumferential surface, the lower damper is provided with a second inner circumferential surface and a second outer circumferential surface, and the first inner circumferential surface and the second inner circumferential surface are fixedly arranged at the upper part and the lower part of the first shell respectively; a through hole penetrating through the thickness direction of the second shell is formed in the center of the second shell, the first shell is located in the through hole, and the first peripheral face and the second peripheral face are fixedly connected with the upper portion and the lower portion of the second shell respectively. The passive radiator sound box has the advantage of ensuring low-frequency definition and plumpness.

Description

technical field [0001] The invention belongs to the technical field of sound boxes, and in particular relates to a passive radiator sound box. Background technique [0002] In order to obtain a better low frequency effect, small speakers generally use passive radiators to improve the low frequency, but when using passive radiators to play music, it is easy to move or even jump. The main reason is that the passive radiator swings Too much energy cannot be attenuated in time, causing the entire speaker to move, which in turn affects the clarity of the low-frequency sound of the speaker, resulting in a reduction in the low-frequency sound quality. The passive radiator swings too violently and the energy cannot be attenuated in time, which will in turn affect the vibration of the speaker diaphragm and affect the clarity of the high-frequency sound of the speaker. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a passive radiator sound box,...
