Earphone

Abstract

The invention relates to an earphone comprising a housing and a speaker disposed at the inner rear of the housing. A housing inner cavity in front of the speaker forms a front cavity. A first partition is disposed in the front cavity and provided with one to a plurality of sound holes, each which is covered with a diaphragm; the diaphragm on at least one sound hole is a gapped half diaphragm. The front cavity is also provided with an inner second partition close to the sound outlet end of the front cavity. The second partition is provided with a plurality of through holes in spaced circles and close to the perioral edge of the second partition. The front peripheral edge of the second partition is provided with a circular stop edge, and a plurality of unit partitions are fixed on the inner ring wall of the circular stop edge at intervals. The unit partitions divide space between the second partition and the front end wall of the front cavity into a plurality of unit cavities on the periphery and a central cavity communicated with every unit cavity. The front end wall of the front cavity is provided with a sound outlet communicated with the central cavity. The earphone is simple in structure, ingenious in design and capable of producing ideal sound effect, and has low 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
