Abstract (en)
The Invention relates to an active noise reduction loudspeaker component of a headset, comprising a loudspeaker frame (110), wherein the middle of the loudspeaker frame (110) has a housing hole (112); a loudspeaker magnet (130) housed into the housing hole (112); a loudspeaker coil (150) positioned in a groove of the loudspeaker magnet (130); a loudspeaker diaphragm (170) covered at an opening end of the loudspeaker frame (110); a noise reduction circuit board (210) fixed to the back surface of the loudspeaker frame (110); and a noise reduction microphone (230) connected to the noise reduction circuit board (210) through a microphone line (220) and installed near the loudspeaker frame (110), wherein a gap among the loudspeaker frame (110), the loudspeaker magnet (130), the loudspeaker coil (150) and the loudspeaker diaphragm (170) forms an acoustic cavity. The invention is implemented to obtain a light and dexterous active noise reduction loudspeaker component of a headset capable of reducing the cost, so as to entirely reduce the volume of the headset and reduce the cost of the headset.
