Tool, Bluetooth technology are global opens, have compatibility well in the world, and the whole world can pass through low cost
Invisible bluetooth network is connected, and is either listened to music by bluetooth headset still by all and its convenient, but existing bluetooth
Earphone noise reduction capability is limited, additionally, due to microphone apart from sound source too far so that speech quality is affected.
Utility model content
The technical problems to be solved in the utility model is to overcome the above technological deficiency, provides a kind of comfortable wearing, is not easy to slide
De-, voice communication effect is more preferable, a kind of more superior bluetooth noise cancelling headphone of sound insulation and noise reduction performance.
In order to solve the above technical problems, technical solution provided by the utility model are as follows: a kind of bluetooth noise cancelling headphone, including shell
Body, the enclosure interior are successively arranged open source single-chip microcontroller, Bluetooth Receiver and battery from top to bottom, set on the shell
There are operation button and USB charging hole, the USB charging hole corresponds to battery placement, and the housing bottom charges close to USB
Hole is equipped with indicator light, and the housing bottom is hingedly equipped with connecting rod, and the connecting rod is equipped with Answer Key and microphone, described
Case top is connected with ear-hang, and the other end of the ear-hang is connected with loudspeaker, and the loudspeaker are equipped with earplug, described
Earplug include round acoustic aperture, be equipped with sound absorbing layer around circle acoustic aperture, be equipped with Anti-slip cover, the open source monolithic around sound absorbing layer
Machine is electrically connected with operation button, Bluetooth Receiver, battery, indicator light, Answer Key, microphone and loudspeaker respectively.
The utility model compared with prior art the advantages of be: shell is connect by ear-hang with loudspeaker, is hanged by ear-hang
It hangs on ear, convenient for wearing, the earplug that loudspeaker are equipped with is made of round acoustic aperture, sound absorbing layer and Anti-slip cover, round acoustic aperture side
Just the transmission of speaker sound, sound absorbing layer efficiently completely cut off external noise, and Anti-slip cover improves the stability that loudspeaker are placed on earhole, significantly
Increasing the use feeling of user, the connecting rod that housing bottom is connected with may be rotated by the hinged relationship with shell, from
And the microphone on connecting rod is furthered at a distance from sound source, improve speech quality.
As an improvement, the operation button include volume add, power switch and volume down.
As an improvement, protective cover, one end of the protective cover and housing hinge are snapped in the USB charging hole,
Prevent dirty blocking USB charging hole.
As an improvement, the sound absorbing layer is made of acoustical cotton material, acoustical cotton acoustic absorptivity is high, and sound insulation value is good, and
With excellent waterproof, moisture-proof and permeability, increase the comfortable experience of wearing.
As an improvement, the Anti-slip cover and ear-hang is made of silica gel material, earplug is equipped with made of silica gel material
Anti-slip cover can prevent earphone from falling off during wearing, while certain guarantee, ear are provided for the soundproof effect of sound absorbing layer
It hangs and further improves the stability of bluetooth headset wearing, the ear-hang made of flexible silica gel can be comfortably suspended on
On ear, without worrying falling off for bluetooth headset again.
