a kind of earphone

Abstract

The invention relates to an earphone, which comprises a housing and a horn built in the rear of the housing. The inner cavity of the housing at the front of the horn forms a front cavity, and a first partition is arranged in the front cavity. There are three sound holes and each sound hole is covered with a diaphragm, and the diaphragm on at least one sound hole is a half-diaphragm with a gap; the front cavity is also provided with a second partition near the sound outlet end. The spacer ring is provided with a plurality of through holes on the position close to the peripheral edge of the second partition; the peripheral edge of the second partition front side is provided with an annular retaining edge, and the inner ring wall of the annular retaining edge is fixed at intervals with A plurality of unit partitions, each unit partition divides the space between the second partition and the front end wall of the front cavity into a plurality of unit cavities located in the periphery and a central cavity located in the center and communicated with each unit cavity, the front cavity A sound outlet communicating with the above-mentioned central cavity is opened on the front end wall. The invention has simple structure and delicate design, can produce ideal sound effects and can reduce damage to human ears.

Description

technical field [0001] The invention relates to an earphone. Background technique [0002] People often use earphones to listen to music or answer calls. The purity of the sound produced by the earphones and the high, medium, and bass effects directly affect people's hearing experience. Especially music enthusiasts have very strict requirements on the sound effect of headphones. Headphone manufacturers have always regarded improving the sound effect of headphones as their main research and development goals. Since the headphones realize sound transmission through sound-to-electricity conversion, the headphone manufacturers often only focus on reducing electrical signal interference and improving signal quality. In terms of purity, the improvement in the physical structure of the earphones is minimal, which makes the manufacturers achieve mediocre results while spending a lot of manpower and material costs. [0003] The earphone generally includes a housing and a speaker bu...

AI Technical Summary

Problems solved by technology

In the existing earphones, the sound effect is completely dependent on the performance of the speaker. Therefore, the requirements for the performance of the speaker are very strict. At the same time, it is difficult to produce a satisfactory sound effect by relying on the speaker alone.

In addition, in the existing earphones, the speaker is often directly facing the human ear, and the sound produced by the speaker is directly transmitted to the human ear without any shielding. If worn for a long time, it will cause damage to the human ear, and it is easy to cause serious consequences such as tinnitus and deafness. In-ear headphones are more damaging
