Abstract

The invention discloses an earphone, which comprises a loudspeaker unit, an audio signal line electrically connected to the loudspeaker unit, a housing for accommodating the loudspeaker unit, and a front cover laid on the housing; the front cover The space between the speaker unit and the speaker unit forms a front acoustic cavity, and the space between the housing and the speaker unit forms a rear acoustic cavity; wherein the rear acoustic cavity is divided into a main rear cavity and a bass rear cavity by a partition wall. A sound guide is laid in the cavity of the bass rear cavity, and the sound guide is curved and filled in the cavity of the bass rear cavity, one end of which is connected to the main rear cavity through the through hole of the partition wall, and the other end is passed through The sound outlet hole on the shell of the bass rear cavity communicates with the outside world. The earphone structure provided by the technical solution effectively improves the low-frequency performance and the intermediate-frequency performance of the earphone, and on the basis of ensuring the stability of the earphone, the appearance of the earphone is more beautiful.

Description

technical field [0001] The invention relates to the technical field of audio equipment, in particular to an earphone with a bass rear chamber. Background technique [0002] As high-quality smart phones, Pads and other portable electronic products are widely used in daily work and life, people have higher and higher requirements for matching earphones. High-fidelity sound quality performance, so high-fidelity headphones have become a market trend. Headphones are divided into in-ear, on-ear and semi-in-ear according to different wearing methods. Due to the poor wearing comfort of in-ear earplugs, the potential safety risks caused by insufficient perception of background sound during use, and the consideration of hearing protection, On-ear and semi-in-ear earplugs are becoming more and more popular among consumers. [0003] Due to the natural sound leakage between the earphone and the ear canal when worn, the low frequency performance of on-ear / semi-in-ear earphones is usuall...
