Description

A kind of earphone

Technical field

The utility model is related to acoustic-electric energy-conversion technique fields, more specifically, the utility model is related to a kind of earphones.

Background technology

Earphone is a pair of of acoustic-electric converting unit, it receives the electric signal that media player or receiver are sent out, utilizes patch The loud speaker of nearly ear converts it into the sound wave that can be heard.Earphone is usually separable with media player, utilizes one A plug connection.Benefit is can to listen to sound equipment alone in the case where not influencing other people；Also the sound of ambient enviroment can be separated, It is helpful to the people used under noisy environment of making an uproar in recording studio, DJ, journey, movement etc..

In the prior art, earphone is divided into open earpiece and closed earphone in structure design, is limited to mechanism, only A kind of single sound quality can be generated.The shell of closed earphone is closed, is used in profession is monitored very much.Clear sound, Details is abundant, and low frequency response is good, but closed earphone wearing has closed sense for most people, still another shortcoming is that low Sound sound dye is serious.Open earpiece is current popular earphone pattern.The characteristics of such earphone is earphone back cavity blow-by, But it is connected in the external world by housing openings so that sense of hearing is natural.But low frequency loss is larger when its disadvantage, and low frequency is accurate.Ear Machine on pattern in be divided into In-Ear, half In-Ear and headphone, the general muff-style designs of wear-type are bigger, are provided simultaneously with A piece flexible head hoop, auricle is clamped from overhead.Due to not having to consider that light and handy problem, earmuff are generally designed to compare Greatly, this earphone develops very perfect, can generally accomplish that headband is adaptive, and earmuff can rotate by a small margin, can allow wearing Become more comfortable.But it is not appropriate for portable, even if headband is designed to folding, therefore relatively it is suitble at home or does The fixed positions such as public domain point use.Difference on effect of the audio of open earpiece and closed earphone in headphone is very Obviously so that with a earphone be difficult the needs for meeting different crowd simultaneously.

Therefore, it is necessary to provide a kind of improved earphone.
