The present invention provides a kind of bluetooth earphone, can be connected by bluetooth module 170 with electronic equipment (not shown), including ear
Machine 110, attachment means 120, memory 140 and processor 150, microphone array is provided with the attachment means 120
130, for gathering sound source, the sound source is to include ambient noise and voice messaging.
In the present embodiment, electronic equipment is the electronic equipments such as mobile phone, tablet personal computer.
In the present embodiment, the memory 140 of the bluetooth earphone 10 is used to store a plurality of instruction, the instruction by
Reason device 150 is loaded and performed：The sound source acquisition waveform phase collected according to the microphone array 130 is poor, and according to institute
State waveform phase difference and calculate the substantially dimensional orientation of sound source and noise reduction process is carried out to the sound source using denoising algorithm；It is and right
Voice messaging from Sounnd source direction carries out gain amplification.Processor 150 in embodiments of the invention can use all kinds of tools
The chip of standby disposal ability or control ability, such as CPU (central processing unit) or MCU (microcontroller).The noise reduction process and
The mode of gain amplification, is all that those skilled in the art is understood, is not described in detail then at this.
In the present embodiment, the microphone array 130 includes 4 microphones, and two of which microphone is arranged at institute
State position near from user's sound source on earphone, i.e. the position nearer from mouth；Another two are then arranged on the earphone from user
The remote position of sound source.
In the present embodiment, the attachment means 120 are neck ring.Wherein, the neck ring is shaped as semi-circular, i.e. class
It is similar to the annular do not closed of the shapes such as c-type, the U-shaped or shape of a hoof.The semiorbicular both ends are drawn close to centre, are connected in both ends
Between position it is curved.In the present embodiment, such shape facilitates the wearing of user, and comfort is more preferable.
In the present embodiment, 4 microphones in the microphone array 130, wherein two be respectively arranged at it is described
The both ends of neck ring, other two microphones are arranged at the middle part of the neck ring, and the middle part is when wearing
Positioned at the collare position of user.In the present embodiment, such microphone sets the voice letter helped to gather from sound source
Breath.In use, the microphone for being arranged at the both ends is near apart from user's sounding position, i.e., its sound that collects near from sound source
In, voice messaging can be bigger than ambient noise；And the microphone of middle part is arranged at due to from sound source farther out, its sound collected
Ambient noise is bigger than voice messaging in sound.DSP (Digital Signal Processing) can be according to environment in the sound that each microphone gathers
The size of noise and voice messaging, determine in the sound that the microphone is collected be based on ambient noise or voice messaging as
It is main.DSP functions can be incorporated into processor 150, can also be completed by independent chip.Thereby assist in and believe voice
Breath separates from ambient noise.
