Abstract

The invention discloses an earphone structure and a terminal. The earphone structure comprises: an earphone back cover and an earphone front cover that are mutually engaged, and a moving coil unit, aMEMS unit and a sound cavity structure disposed in an accommodation space formed by the earphone back cover and the earphone front cover, wherein the sound cavity structure is provided with a first sound cavity and a second sound cavity which are disposed apart, the first cavity wall of the first sound cavity is provided with a moving coil unit radiation port, the second cavity wall of the secondsound cavity is provided with a MEMS unit radiating port, and the moving coil unit radiating port and the MEMS unit radiating port are used for outputting sound wave signals. The embodiment of the invention can reduce the generation of acoustic standing waves and reduce the influence of harmonic distortion, thereby effectively improving the high-fidelity sound quality effect of the earphone.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an earphone structure and a terminal. Background technique [0002] In the prior art, a side-firing earphone usually includes a support part, a housing and a speaker unit. The speaker unit is arranged in the housing, and the speaker unit divides the inner chamber of the housing into a front chamber and a rear chamber. Among them, the front cavity is close to the diaphragm of the speaker unit, and the sound is output from the front cavity side. However, due to the influence of the side wall of the front cavity, the high-frequency sound performance may be greatly attenuated, and the high-fidelity sound cannot be guaranteed. Contents of the invention [0003] Embodiments of the present invention provide an earphone structure and a terminal to solve the problem in the prior art that side-firing earphones have poor high-frequency sound performance and cannot ensure high-fidel...
