Sound bandwidth, filter out low frequency (<200Hz) with high frequency (>4000Hz), voice is amplified into (30~40dB), so as to fulfill inciting somebody to action
Sound of giving orders or instructions understands reproduction, greatly promotes speech quality, exempts the unclear puzzlement of the small earphone call of sports type bluetooth；Referring to Fig. 6,
To filter out the fundamental diagram of noise；Wherein VM=gives orders or instructions greatly sound+environmental noise；Small sound+the environmental noises of giving orders or instructions of VS=；
Vout=(VM-VS) * 30~40dB
* 30~40dB of={ (sound+environmental noise of giving orders or instructions greatly)-(small sound+environmental noise of giving orders or instructions) }
=small 30~the 40dB of sound * that give orders or instructions
VBPFThe small sounds of giving orders or instructions of=30~40dB*
The small following low frequency -4000Hz more thans high frequencies of the sound -200Hz that gives orders or instructions of=30~40dB*
=high definition is given orders or instructions sound
The size of signal difference between main microphon 8 and secondary microphone 9, influences the clarity of speech quality, therefore how
Signal difference between main microphon 8 and secondary microphone 9 is made to obtain the technology of maximization, be to make main microphon 8 and secondary microphone 9 with
The range difference in the source of giving orders or instructions, such as Fig. 7 are sent by first speaker oral cavity, the signal difference relational graph between main microphon 8 and secondary microphone 9.
Distance=A the distances for source and the main microphon 8 of giving orders or instructions,
Distance=B the distances for source and the secondary microphone 9 of giving orders or instructions,
The distance that dual microphone differential amplifier will acquire optimal signal difference of giving orders or instructions is
∣ A distance-B Ju Li ∣>=main-pair range difference (>=7 centimeters),
It it is about 10 centimeters with the master in Fig. 7-pair range difference, more than 7 centimeters.With 85dB give orders or instructions source when, main microphon 8 with
9 sound press difference about 7~8dB of secondary microphone.
After integrally assembling, can relevant parameter setting be made by the software program in MCU, as touch-control sensitivity,
Effective touch-control time, invalid touch-control time, the length of one's sleep, deep sleep time, abnormal time etc.；And various operation modes.
Such as music playing mode：Short-press 1 time is plays or pause function；Short-press 2 times is next Qu Gongneng；Short-press is for 3 times
Upper one is bent；
Call alerting mode：Short-press 1 time is pickup feature；Long-press 1 second is receiving rejection function；
Call mode：Short-press 1 time is hangs up function.
In touching, referring to Fig. 8, the small charge variation of human body is perceived by sheet metal 102, thus small charge variation
Input to touch-control IC modules is converted into I2C data, sends MCU to and makees related data detection and be converted to GPIO data to be transmitted to touch-control IC
Module makees corresponding control, such as broadcasting, pause, next bent and upper song operation, it can be achieved that multiple functions operate, and operate simple
Singly, conveniently.
