Abstract

The invention discloses an earphone which comprises a shell and a horn arranged in the shell, wherein the horn divides the internal space of the shell into a front cavity positioned at the front side of the horn, and a rear cavity positioned at the rear side of the horn, the shell is provided with a front wall frontally opposite to the horn, and a side wall obliquely extending to the horn side from the periphery of the front wall, a first sound outlet hole communicated with the front cavity of the shell with the outside is arranged on the front wall, a second sound outlet hole communicated with the front cavity of the shell with the outside is arranged on the side wall, when the earphone is placed in the external ear of the ear for use, the first sound outlet hole is used for being opposite to the auricular concha of the external ear, and the second sound outlet hole is used for being opposite to the external auditory canal of the external ear. The earphone has a better sound output effect.

Description

technical field [0001] The invention relates to an earphone, in particular to an earplug earphone. Background technique [0002] The existing earphone usually includes a casing and a speaker disposed in the casing, wherein the speaker divides the space in the casing into a front cavity and a rear cavity. The casing has a front wall located on the front side of the horn, and the front wall is provided with a sound hole for communicating the front cavity with the outside, so as to send out sound waves when the horn is working. Since the sound outlet is directly facing the speaker, the earphone can output better mid-range and high-frequency sound, but the effect of outputting low-frequency sound is poor. [0003] In order to achieve a better low-frequency output effect so that the human ear can obtain a better sound experience, a circular protrusion is usually protruded outward on the front wall of the housing in the existing earphones, and the sound outlet is set At the end ...
