Module, the audio analysis module connect the process chip, and the receiving terminal of the bluetooth communication module connects the processing core
Piece, the process chip connect the loudspeaker, the process chip connecting valve module.Since everyone has different sounds
Frequently, therefore, the utility model utilizes this characteristic, and audio analysis module is set on the circuit of microphone, and by audio analysis mould
Block connects voice data memory module, when user is using the earphone, is previously read one section and is arranged on voice data storage
A segment standard sentence in module, user's sound record the audiorange of user after audio analysis module analysis
In voice data memory module.When user carries out call voice using the utility model earphone, filtered audio module can
The not voice in user's audiorange, noise to be filtered out, ensure the clear transmission of user's sound, realize special messenger
It is dedicated to remove noise earphone.
The distinctive audiorange of user determines that method is, after reading a segment standard sentence, each word can have one
Audio value, if first character audio value is 30HZ, suitably relaxes audiorange and is denoted as 29HZ-31HZ, second word audio value
For 31HZ, then 30HZ-32HZ is denoted as, and so on, finally definite user's audiorange is：29HZ-32HZ, by the audio model
Enclose and be stored in voice data memory module, as long as audio not within the range, filtered audio module is filtered without exception, only
The sound retained in the audiorange is transmitted by bluetooth communication module.
Play opening/closing earphone and use state is determined by switch module into acoustic pattern.
Preferably, the circuit between the receiving terminal of the bluetooth communication module and the process chip is equipped with noise reduction mould
Block.Set noise reduction module the voice of the other side received can be done noise reduction process in receiving circuit, ensure user itself
During the clarity of sound transmission so that receive other side's sound also as far as possible clearly, improve speech quality.
Preferably, the noise reduction module is connected with noise gathering module, the process chip is connected with manual noise reduction and opens
Close.The signal that noise reduction module receives is divided into noise signal, doubtful noise signal and voice signal, and noise signal is directly dropped
Module of making an uproar eliminates, and noise gathering module is stored doubtful noise signal, when user is answering other side's voice, is felt
Noise still exists, that is, presses manual noise reduction switch so that process chip thinks that doubtful noise is also noise and eliminates, into one
Step ensures call clarity.If user does not press manual noise reduction switch, then it is assumed that it is good to answer clarity.Manually drop
Switch make an uproar to make feedback with will not allow the benefit of the excessive noise reduction of noise reduction module, it is possible to achieve successive elimination noise.
Preferably, the switch module connecting valve button.Switch key Perceived control is more directly perceived, by switch key come
Adjust the pattern switching of earphone.
The utility model is through using proof, effect is preferable, simple and practical.
