CENTRAL NOISE REDUCTION LOUDSPEAKER

摘要

A central noise reduction loudspeaker includes a speaker unit, a top cap, a seat body, and a microphone. The speaker unit includes a diaphragm, and the diaphragm includes a central through hole located at center of the diaphragm. The top cap covers the seat body, and the speaker unit is disposed between the top cap and the seat body. The top cap includes a central fixed frame penetrating the central through hole of the diaphragm. The microphone is disposed within the central fixed frame and located in the central through hole. Since the microphone is disposed in central through hole, compared to conventional, the front cavity and the overall size of the loudspeaker or earphone can be reduced and the production process can be simplified.
