earphone

Abstract

An earphone comprises an earphone housing and a cover assembly matching to and combined with the earphone housing, wherein the earphone housing and the cover assembly are formed with a cavity for accommodating a speaker structure, the speaker structure comprises a vibration diaphragm, a space between the vibration diaphragm and the cover assembly is a front acoustic cavity, the cover assembly is provided with an audio tuning hole thereon, an audio tuning member is correspondingly combined in the front acoustic cavity at a position near the audio tuning hole, the audio tuning member is a slidable structure which can slide reciprocatingly in two opposite directions and realize opening / closing correspondingly. The earphone changes low frequency response parameters of the earphone by providing an audio tuning structure in a front acoustic cavity, thereby changing the sound characteristic of the earphone to obtain a different acoustic quality effect and can satisfy more requirements for different acoustic quality effects of consumers.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to an earphone. Background technique [0002] At present, there is no doubt that earphones, as an electro-acoustic device, have been closely related to people's daily life and work. It is not difficult to find the existence of earphones at home, outdoors, important conference sites, hearing tests, etc. , earphones have become a symbol of people's portable audio. According to the wearing form of earphones, they can be divided into different types such as earplugs, ear-mounted, in-ear and head-mounted. Among them, earphones are usually small and easy to carry, and have high market circulation. It is loved by many consumers. [0003] Obviously, different users often have different requirements for the sound quality of earphones, and ordinary earphones include a speaker unit as a sound unit and a speaker cover assembly that forms a front cavity with the speaker unit. The speaker cover ...

AI Technical Summary

Problems solved by technology

[0003] Obviously, different users often have different requirements for the sound quality of earphones, and ordinary earphones include a speaker unit as a sound unit and a speaker cover assembly that forms a front cavity with the speaker unit. The speaker cover assembly usually includes a front The cover and the sound tube are often provided with sound leakage holes on the front cover. This kind of headphone structure does not have a structure that can adjust the sound quality effect, so generally there is only one sound quality, which can only cater to the preferences of some users, and the other part uses The needs of consumers cannot be met in ordinary earphones

Therefore, it is necessary to provide a new earphone structure, which focuses on solving the problem that the sound quality of the existing earphones cannot be adjusted, so as to adapt to the different needs of more consumers for sound quality effects.
