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, t

Embodiment Construction

[0023] With reference to the accompanying drawings, the earphone of the present invention comprises a housing 1 and a speaker 2 built into the rear of the housing 1. The housing cavity at the front of the speaker 2 forms a front cavity, and a first partition 3 is arranged in the front cavity. One or more sound holes 4 are provided on the plate 3 and each sound hole 4 is covered with a diaphragm 5 , and the diaphragm 5 on at least one sound hole 4 is a half diaphragm 51 with a notch 6 opened thereon. In the above structure, the first partition separates the 3 front cavities, which can effectively block the direct impact of the speaker's sound on the human ear and reduce the damage to the human ear. At the same time, by changing the structure of the front cavity, the rebound and overlap of sound waves are increased, thereby enhancing the stereoscopic effect of the sound. The structure of the sound hole 4 and the diaphragm 5 is set, and the diaphragm on at least one sound hole 4 ...

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...
