A sounding device and electronic equipment

Abstract

Provided in an embodiment of the present invention are a sound emission device and an electronic apparatus. The sound emission device comprises a vibration system, a magnetic circuit system, a housing and an antenna. The housing comprises an installation portion having at least one open end, and a rear cavity portion correspondingly arranged at an outer side of a first sidewall of the installation portion for formation of a rear cavity. The magnetic circuit system and the vibration system are fixed inside the installation portion. The first sidewall is provided with a rear sound hole arranged at a position facing the rear cavity and used to communicate a magnetic gap in the magnetic circuit system and the rear cavity. The antenna is provided at the sound emission device. The embodiment of the present invention enables a sound emission device to have a reduced size while achieving favorable acoustic performance. Moreover, an antenna can be integrated into the compact sound emission device to increase the level of integration.

Description

technical field [0001] The invention relates to the technical field of sound generating devices. Background technique [0002] With the development of consumer electronic products, the miniaturization design of consumer electronic products has attracted more and more attention. As a component of electronic products, sound generating devices have higher and higher requirements for integrated design. The integrated design of the sound generating device and the antenna has become a trend of technological development. [0003] In the existing technology, in order to improve the acoustic performance of terminal products, it is often necessary to assemble two acoustic components at the upper and lower ends. There are three main methods: one is to assemble a Receiver at the upper end and an SPK module at the lower end. This method exists The defect of low volume; the second is to assemble an SPK module on the upper and lower ends at the same time. Compared with the first method, ...

Problems solved by technology

[0003] In the prior art, in order to improve the acoustic performance of terminal products, it is often necessary to assemble two acoustic components at the upper and lower ends. There are three main methods: one is to assemble a Receiver at the upper end and an SPK module at the lower end. This method exists The defect of low volume; the second is to assemble an SPK module on the upper and lower ends at the same time. Compared with the first method, the sound effect of this method is better, but the sealed rear cavity will occupy a large space, which is not conducive to the small size of the product. The third is to assemble an SPK module at the lower end and an SPK with an open rear cavity at the upper end. Compared with the previous two methods, the volume and space occupied by this structure are improved, but the vibration of the rear shell of the mobile phone will be more serious

[0004] In the above centralized situation, limited by the volume of the sound generating device, its integration with the antenna is low, it is difficult to adapt to electronic products with high integration requirements, and it is difficult to balance both miniaturization and excellent acoustic performance. need
