Specific implementation mode
To make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, with reference to
Specific implementation mode, the present invention is further explained.
The noise cancelling headphone 10 of the embodiment of the present invention includes for playing the pronunciation unit 11 of audio, for picking up pronunciation unit
Pickup microphone 12, the input signal for providing pickup microphone 12 of the noise audio signal in space belonging to 11 are divided into two
The audio splitter 13 on road and noise reduction unit 14 for generating noise reduction audio signal, pickup microphone 12 are located at pronunciation unit 11
Side, pickup microphone 12, audio splitter 13 and noise reduction unit 14 are sequentially connected electrically, and it is single that noise reduction unit 14 is electrically connected to pronunciation
Member 11.Input signal can be divided into two-way by adding audio splitter 13 inside earphone and export to noise reduction unit 14 and
Outer audio equipment 20 so that earphone has and can be tested to earphone noise reduction index by the interface of user test, user
And to earphone anti-acoustic capability adjusting and optimizing.
Based on above-mentioned earphone 10, an embodiment of the present invention provides test the earphone and adjust the side of the earphone noise reduction parameters
Method, this method comprises the following steps：
S10：Audio splitter receives the input signal that pickup microphone provides and is divided into two-way output；
S20：External audio unit receives the output signal of audio splitter, and obtains noise parameter；
S30：External audio unit receives user demand and analyzes noise parameter, obtains noise reduction parameters, and output this to
Noise reduction unit；
S40：Noise reduction unit receives the output signal of output signal and external audio unit in audio splitter and by drop
Parameter of making an uproar generates noise reduction audio, then exports to pronunciation unit.
In the present embodiment, external audio unit 20 includes test cell 21, parameter adjustment unit 22 and sound card 23, test
