As a preferred embodiment, the shape of the shell is round or oval.
As a preferred embodiment, the shell has towards the one side of the noise reduction microphone accommodates the microphone lines
Groove.
As a preferred embodiment, the center of the noise reduction microphone can deviate the 5mm at the front center of the loudspeaker
Within.
Implement the utility model, can be realized at least following audio frequency effect: noise reduction microphone is being mounted on loudspeaker just
The center in front, the frequency of 10Hz-1kHz, earphone phase are can be controlled within 120 degree, can reach best noise reduction effect.
Noise reduction microphone is placed in parallel with the loudspeaker, loudspeaker described in the radio reception face face of the microphone, and absorbing sound and lowering noise effect is more preferable.
In shrinkage pool can 1 or 2 microphones of longitudinal stack, be installed in the center in the front of loudspeaker, noise reduction effect is more preferable.Most
Good, 2 microphones of longitudinal stack, are installed in the center in the front of loudspeaker in shrinkage pool, in the condition of save the cost
Lower effect is best.Circuit board is equipped with bluetooth module, can be realized bluetooth headset function.Shell is towards the noise reduction microphone
There is the groove for accommodating the microphone lines on one side, make more compact structure.The center of noise reduction microphone can deviate the loudspeaker
Within the 5mm at front center, noise reduction effect is influenced little.
Below in conjunction with accompanying drawings and embodiments, the utility model is described in further detail.
