Abstract

The invention discloses an acoustic device, comprising a sounding unit, the sounding unit includes a vibrating diaphragm, and the acoustic device is provided with a sound outlet, wherein, the rear side of the vibrating diaphragm forms a first closed cavity, and the cavity wall of the first closed cavity A mounting hole is opened on the mounting hole, a flexible deformation part is provided on the mounting hole, a second closed cavity is provided outside the first closed cavity, and the flexible deformation part is located between the first closed cavity and the second closed cavity; the cavity wall includes It is used to install the first wall of the flexible deformation part, and the first wall is provided with a through groove that is sunken toward the direction of the first airtight cavity; the installation hole is provided with a protective piece at the position facing the flexible deformation part, and the protective piece is provided with Penetrating air holes; the protective piece includes a bottom wall and one or more extension walls located on one side of the through groove, the extension walls are inclined-plane structures, the extension walls are provided with air holes, or both the extension walls and the bottom wall are provided with air ventilation holes. hole. The acoustic device in the present invention can prevent the acoustic device from being blocked, and effectively prevent the flexible deformation part from being damaged.

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 ...
