Abstract

The invention provides an acoustic device, comprising: a sounding unit, the sounding unit includes a vibrating diaphragm, the rear side of the vibrating diaphragm forms a first airtight cavity, the cavity wall of the first airtight chamber is provided with a flexible deformation part, the first airtight chamber A second airtight chamber is provided on the outer side of the body, and the flexible deformation part is located between the first airtight chamber and the second airtight chamber; the acoustic device also includes an adsorption component located in the first airtight chamber, and the adsorption member can increase the volume of the first airtight chamber. Effective volume; the adsorption component is fixedly combined with the flexible deformation part on one side of the first closed cavity, and the adsorption component and the flexible deformation part vibrate synchronously; the first closed cavity is provided with an escape space for avoiding the adsorption component. This structure combined with the adsorption component 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 the acoustic 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 ...
