Abstract
The utility model relates to field of audio devices, relates in particular to a kind of earphone.A Multi-audio-frequency general headrest, comprises housing and handle, and described housing consists of front end housing and back cover, and described front end housing mounts cover on back cover, offers axial passage in described handle, and described passage is communicated with the resonant cavity in housing; In described resonant cavity, be provided with horn single body, the opening part of described channel bottom seals by block, on handle side wall, offer the steam vent with channel connection, taper knob is equipped with tuning ring, on described tuning ring, offer homophony sound hole, tuning ring makes homophony sound hole all be communicated with steam vent, partly be communicated with or be not communicated with by rotation.The utility model is by changing gas output and the air-flow velocity of steam vent, thereby the adjusting of realization to earpiece audio makes this earphone can produce various audio frequency effect, the demand of discontented different user.
Description
Technical field
The utility model relates to field of audio devices, relates in particular to a kind of earphone.
Background technology
Present various electronic equipment such as PAD, MP3, mobile phone even computer etc. all can supporting earphones, so that can hear smoothly in public places equipment sound, can not affect other people again.Earphone can also improve tonequality to a certain extent, and how the National People's Congress listening to the music can be equipped with earphone specially.The volume adjusting of existing earphone is divided into two kinds of patterns, a kind of is to carry out volume adjusting in player end, another kind is that the volume that knob that size of current regulates regulates earphone is set on earphone circuit, and above-mentioned two kinds of regulative modes all cannot be realized the tonequality of earphone itself is regulated.A kind of earphone can only provide the sound of simple a kind of tone color level frequency effect characteristic.Can only provide a kind of audio, cannot to audio frequency, regulate according to different user demands, song self character; The earphone that is for example applicable to high middle pitch just cannot be used for listening the music of bass, like this for the headset user of having relatively high expectations, just need to have the earphone of number of different types, has so not only increased equipment cost, and it is also very inconvenient to portably use.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Multi-audio-frequency general headrest, this earphone is by changing gas output and the air-flow velocity of steam vent, thereby realize the adjusting to earpiece audio, make this earphone can produce various audio frequency effect, the demand of discontented different user.
The utility model is achieved in that a kind of Multi-audio-frequency general headrest, comprise housing and handle, described housing consists of front end housing and back cover, and described front end housing mounts cover on back cover, in described handle, offer axial passage, described passage is communicated with the resonant cavity in housing; In described resonant cavity, be provided with horn single body, the opening part of described channel bottom seals by block, on handle side wall, offer the steam vent with channel connection, taper knob is equipped with tuning ring, on described tuning ring, offer homophony sound hole, tuning ring makes homophony sound hole all be communicated with steam vent, partly be communicated with or be not communicated with by rotation.
Described horn single body is arranged between front end housing and back cover, by horn single body, resonant cavity is separated near the high pitch inner chamber of front end housing one side and the bass inner chamber of close back cover one side.
Described passage is communicated with bass inner chamber.
Described handle is that the extension of back cover rear portion forms, and back cover and handle are as a whole.
Described steam vent is circular port, and described homophony sound hole is along channel axis to the slot arranging.
On described tuning ring, be also provided with auxiliary sound regulating hole, described auxiliary sound regulating hole is opened in the opposite of homophony sound hole, and the aperture of auxiliary sound regulating hole is half of homophony sound hole.
The utility model Multi-audio-frequency general headrest by arranging a rotatable tuning ring on handle, and the residing region division of tuning ring has the steam vent being communicated with resonant cavity, and on tuning ring, correspondence arranges sound regulating hole; When tuning ring rotates, can change gas output and the air-flow velocity of steam vent, thereby realize the adjusting to earpiece audio, make this earphone can produce various audio frequency effect, the demand of discontented different user.
Accompanying drawing explanation
