Abstract (en)
[origin: EP4040799A1] Embodiments of this application provide a microphone-loudspeaker combined module, a headset, and a terminal device. The microphone-loudspeaker combined module includes a microphone, a loudspeaker, and a PCB. The microphone has a microphone front cavity, the loudspeaker has a loudspeaker front cavity, and the microphone front cavity communicates with the loudspeaker front cavity. The microphone and the loudspeaker are disposed on the PCB, a signal processing unit is disposed on the PCB, and the microphone and the loudspeaker are electrically connected to a signal processing chip separately. In this application, the microphone and the loudspeaker are disposed on the PCB and the microphone front cavity communicates with the loudspeaker front cavity, so that the microphone and the loudspeaker can share the front cavity, thereby improving space utilization of the microphone and the loudspeaker, and resolving a problem that the loudspeaker and the microphone occupy large space.
