Document Type and Number:

WIPO Patent Application WO/2021/052243

Kind Code:

A1

Abstract:

Embodiments of the present application provide a speaker and a terminal. The speaker comprises a housing having an accommodation space and a sound producing unit fixed in the accommodation space. The sound producing unit has a vibration diaphragm that vibrates to produce sound. The housing comprises a first inner bottom wall and an inner side wall fixedly connected to the first inner bottom wall. The vibration diaphragm and the inner side wall are fixedly connected to each other so as to divide the accommodation space into a front chamber and a back chamber. The first inner bottom wall is located in the front chamber. A sound outlet hole passes through the inner side wall, and communicates with the front chamber to form a front chamber channel. The vibration diaphragm is disposed obliquely with respect to the first inner bottom wall. The caliber of an end of the front chamber connected to the sound outlet hole is greater than the caliber of another end of the front chamber located away from the sound outlet hole. The invention helps to smooth air flow, reduces the intensity of eddy currents around the surround, reduces noise generation, and improves the sound performance of the speaker.
