Half-loudspeaker module and electronic equipment

Abstract

The embodiment of the invention relates to mobile communication equipment, and discloses a semi-loudspeaker module and electronic equipment. In the present invention, the half-speaker module comprises: a speaker unit; a shell which is arranged in the electronic equipment shell; a front sound cavity which is communicated with a sound outlet hole of the electronic equipment shell and a rear sound cavity far away from the sound outlet hole are formed in the shell; an accommodating area which is communicated with the front sound cavity and the rear sound cavity and is formed between the shell and the electronic equipment shell; a loudspeaker unit which is arranged in the accommodating area to separate the front sound cavity from the rear sound cavity; the shell forms a sound absorption cavity communicated with the front sound cavity in the direction from the front sound cavity to the rear sound cavity, and the sound absorption cavity and the rear sound cavity are isolated from each other. Therefore, the sound pressure level at the high-frequency resonance point can be reduced, the problem of sharp sound at the high frequency can be improved, the effective bandwidth is broadened, the distortion problem of the high-frequency sound is improved, the sound quality is improved, and meanwhile, the manufacturing cost of the semi-loudspeaker module is lower, so that electronic equipment with better sound quality can be manufactured at lower manufacturing cost.

Description

technical field [0001] The embodiments of the present invention relate to mobile communication equipment, in particular to a half-speaker module and electronic equipment. Background technique [0002] The loudspeaker is an important acoustic component in electronic equipment, and it is a transducer device that converts electrical signals into acoustic signals. In the prior art, such as figure 1 As shown, the speaker module generally includes: a casing 10 , a speaker body 20 disposed in the casing 10 , and the speaker body 20 divides the inner cavity of the casing 10 into a front acoustic cavity 30 and a rear acoustic cavity 40 isolated from each other. The front acoustic cavity 30 communicates with the sound outlet 50, and the rear acoustic cavity 40 is a closed structure, which communicates with the outside world only through the damping hole. The inventors found that in the prior art, the acoustic channel of the front acoustic cavity 30 is long and there is a part of the...

AI Technical Summary

Problems solved by technology

The inventors found that in the prior art, the acoustic channel of the front acoustic cavity 30 is long and there is a part of the cavity, so when the speaker unit makes sound, the sound wave in the high frequency band will resonate with the air in the cavity, resulting in sharp sound. And the problem of harmonic distortion is easy to occur, so the sound quality of the speaker module is poor
