A sounding device and electronic equipment

Abstract

Disclosed is a sound production apparatus, comprising a housing and a sound generator. A rear cavity is formed between the housing and the sound generator; the housing is provided with an opening communicated with an outer part of the rear cavity and the sound generator; the periphery of the opening is surrounded by an opening wall, and the top surface of the opening wall is configured to be sealingly connected to an external device to realize sealing of the rear cavity; a filling area is provided in the rear cavity, the filling area is filled with a sound-absorbing material, and the filling area is surrounded by an enclosing wall; at least a portion of the opening corresponds to the filling area, and at least a portion of the opening wall overlaps with the enclosing wall; a packaging part used for sealing the filling area is provided on the top surface of the enclosing wall; an annular elastic gasket having a sealing effect is provided on the top surface of the opening wall; at the position where the opening wall overlaps with the enclosing wall, the annular elastic gasket is pressed on the upper surface of the edge of the packaging part. Further disclosed is an electronic device comprising the sound production apparatus. The present invention can improve the filling volume of the sound-absorbing material, and improve the acoustic performance of the sound production apparatus.

Description

technical field [0001] The invention relates to the technical field of electroacoustic conversion. More specifically, it relates to a sound generating device and electronic equipment. Background technique [0002] Sound generating devices are important acoustic devices in consumer electronics, which are used to convert electrical signals into sound. In recent years, consumer electronic products have developed rapidly. Since consumer electronic products have a design trend of thinner and lighter overall structure, the requirements for the size and structure of each device are becoming more and more stringent. For the sound generating device, it is necessary to reduce the size and ensure the acoustic performance. [0003] In order to further reduce the space occupied by the sound generating device in the electronic product, the sound generating device can be designed to have an exposed cavity structure, and the closed cavity needs to be formed after being assembled with the ...

Problems solved by technology

Therefore, the sound generating device of this structure requires a certain width of the top surface of the wall to fix the mesh, and a certain width of the top surface of the shell to fix the foam, resulting in a thicker wall and shell, which greatly limits the thickness of the shell. The size of the filling area in the body that can accommodate the sound-absorbing material, which in turn limits the improvement of the acoustic performance of the sound-emitting device
