In-ear earphone

Abstract

The invention discloses an in-ear earphone which comprises a shell, a front cavity and a rear cavity which are arranged in the front-back direction are formed in the shell, a sound guide tube is arranged on the outer side wall of the shell, the sound guide tube is communicated with the front cavity, and a first air guide through hole is formed in the position, corresponding to the rear cavity, of the shell; the through pipe is located in the shell, one end of the through pipe is communicated with the front cavity, the other end of the through pipe is communicated with the first air guide through hole, and air in the front cavity moves towards the rear cavity through the through pipe and is guided out of the through pipe, so that the phenomenon of pressure accumulation in the earphone is reduced, pressure relief of the front cavity is realized, and the service life of the earphone is prolonged. According to the in-ear earphone, the problem of airflow impact on the loudspeaker diaphragm caused by too small space of the front cavity is solved, the space of the front cavity can be further compressed, the high-frequency ductility of the earphone is improved, the sound output effect is improved, the miniaturization of the in-ear earphone is realized, and the aesthetic degree is improved.

Description

technical field [0001] The invention relates to the field of earphones, in particular to an earphone. Background technique [0002] In traditional in-ear earphones, in order to improve the aesthetics and fit the ear structure, the overall volume of the earphone is often reduced, resulting in the adaptive reduction of the space in the front cavity of the earphone. However, due to the small space in the front cavity, the user After inserting the in-ear earphone into the ear canal, it is easy to generate airflow impact on the speaker diaphragm when the earphone produces sound, so that abnormal noise is mixed during the sound output process, which affects the user experience. Contents of the invention [0003] The purpose of the present invention is to provide an in-ear earphone to solve one or more technical problems in the prior art, and at least provide a beneficial option or create conditions. [0004] The solution that the present invention solves its technical problem i...
