Description
Technical field
This utility model relates to a kind of ear phone technology field, specifically, particularly to a kind of Novel Bluetooth earphone.
Background technology
Conventional earphone needs to use connecting line between mobile phone, thus its use is much limited, it is impossible to
Motion is conveniently used.By comparison, bluetooth earphone can well solve these problems, has more competitiveness.User's
No matter mobile phone is placed in pocket or briefcase even can easily be dialed and receive calls in another room.This
Outward, the amount of radiation of bluetooth earphone is probably about 1/10th of mobile phone, and the most in this point, bluetooth earphone is for focusing on now
Just there is the biggest captivation in healthy consumer.In order to filter the noise in bluetooth earphone communication process, current bluetooth earphone
Universal with decrease of noise functions.The method of earphone noise reduction has two kinds, active noise reduction and passive noise reduction.Before active noise reduction occurs, fall
Low noise generally uses three kinds of measures, i.e. at sound source noise reduction, in communication process noise reduction and at human ear noise reduction, these are all
Passive passive.And active noise reduction function is through noise reduction system and produces the reverse sound wave equal with ambient noise, by noise
Neutralize, thus realize the effect of noise reduction.Existing bluetooth earphone noise reduction is general, it is impossible to meet the demand of people.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, discloses a kind of new
Type bluetooth earphone, it uses three mikes to collect acoustical signals, and two of which Mike's wind energy preferably catches user voice also
Cutting down background noise, noise then cut down in the environment of the most noisy by the 3rd mike, can extend the logical of earphone simultaneously simultaneously
The words time.
This utility model solves its technical problem and be the technical scheme is that a kind of Novel Bluetooth earphone, including power supply
Button, volume button, microphone key-press, FLASH memory, bluetooth master chip, speaker, display lamp, charging circuit, charging
Mouth, receptor, antenna, filter and be equipped with circuit, second microphone and the first mike；Described power button, volume button and
Microphone key-press is all connected with bluetooth master chip, described bluetooth master chip be built-in with DSP and risc processor, stereo decoding,
Battery charging management, Bluetooth RF and ROM, described FLASH memory is connected with bluetooth master chip, described speaker and instruction
Lamp is all connected with bluetooth master chip, and described charging inlet is connected with charging circuit, and described charging circuit is connected with bluetooth master chip,
Described receptor, second microphone and the first mike are all connected with bluetooth master chip, described antenna and filtering and outfit circuit
Connecting, described filtering and outfit circuit are connected with bluetooth master chip.
As a kind of preferred implementation of the present utility model, described bluetooth master chip uses BC05_Multimedia_
External chip.
As a kind of preferred implementation of the present utility model, described display lamp is by a yellow indicator lamp and a redness
Display lamp forms.
As a kind of preferred implementation of the present utility model, in described charging circuit, it is provided with DC/DC circuit.
As a kind of preferred implementation of the present utility model, described bluetooth master chip is provided with the 3rd mike.
Operation principle of the present utility model is: using three mikes to collect acoustical signal, two of which Mike's wind energy is more
Good seizure user voice also cuts down background noise simultaneously, and noise then cut down in the environment of the most noisy by the 3rd mike,
The air time of earphone can be extended simultaneously.The Bluecore technology using CSR can develop the bluetooth ear of low cost rapidly
Machine；Earphone is realized man-machine interface by button and display lamp, and push button signalling indicates current earphone as the input of earphone, display lamp
State；Bluetooth earphone is a two-in-one equipment, and when playing audio frequency as earphone, it is only used as an outut device and does not has
There is input function, so only speaker operation；When as the wireless headset of mobile phone, it is as the input of a voice
Outut device, it is provided that the two-way full-duplex voice service of 64kbps, mike and speaker work simultaneously.
This utility model compared with prior art has the advantage that
A kind of Novel Bluetooth earphone disclosed in this utility model, uses three mikes to collect acoustical signal, two of which
Mike's wind energy preferably catches user voice and cuts down background noise simultaneously, and the 3rd mike is then in the environment of the most noisy
Abatement noise, can extend the air time of earphone simultaneously；The Bluecore technology using CSR can develop low cost rapidly
Bluetooth earphone.
