Abstract

The invention provides an acoustic device which comprises a sound production unit, the sound production unit comprises a vibrating diaphragm, a first closed cavity is formed in the rear side of the vibrating diaphragm, a flexible deformation part is arranged on the cavity wall of the first closed cavity, a second closed cavity is formed in the outer side of the first closed cavity, and the flexible deformation part is located between the first closed cavity and the second closed cavity; the acoustic device further comprises an adsorption part located in the first closed cavity, and the adsorption part can increase the equivalent volume of the first closed cavity. The adsorption part is fixedly combined to the side, located in the first closed cavity, of the flexible deformation part, and the adsorption part and the flexible deformation part vibrate synchronously; and an avoiding space for avoiding the adsorption part is formed in the first closed cavity. The structure of combining theadsorption part on the flexible deformation part further improves the low-frequency sensitivity of the acoustic device, improves the frequency response of the intermediate frequency, and improves theacoustic performance.

Description

technical field [0001] The present invention relates to the technical field of acoustics, and more specifically, to an acoustic device and electronic equipment installed with the acoustic device. Background technique [0002] Generally speaking, the acoustic system of the traditional structure includes a closed box and a sounding unit arranged on the closed box. A cavity is formed between the closed box and the sounding unit. Due to the volume limitation of the cavity in the acoustic system, the acoustic system Especially small acoustic systems can be difficult to achieve satisfactorily reproducing bass. Conventionally, in order to achieve satisfactory bass reproduction in an acoustic system, two methods are usually used. One is to place sound-absorbing materials in the box of the acoustic system to absorb or desorb the gas in the box and play a role in volume. The effect of increasing and then reducing the low-frequency resonance frequency is to install a passive radiator ...
