A microphone is a transducer for collecting sound signals and converting the collected sound signals into electrical signals.

The accommodating space 110a is used for accommodating the first microphone 120 and the second microphone 130, in other words, the first microphone 120 and the second microphone 130 are disposed in the accommodating space 110 a. The first microphone 120 and the second microphone 130 may be fixed within the housing 110. The positions of the first microphone 120 and the second microphone 130 are not limited.

The first state of the key 150 may be, but is not limited to, the key 150 not being pressed, and the second state of the key 150 may be, but is not limited to, the key 150 being pressed. As long as the first state and the second state of the key 150 are different. In the present embodiment, the first state of the key 150 is described as an example in which the key 150 is not pressed, and the second state of the key 150 is described as an example in which the key 150 is pressed. When the first button 150 is in the first state, the first microphone 120 is turned on and the second microphone 130 is turned off, and the wireless headset 10 can be used in a first scene. The first scenario may be a scenario for personal use, for example, the wireless headset 10 may be used to connect and make a phone call, or listen to a song, or communicate with a communication software by voice, etc. At this point, a single first microphone 120 may satisfy the requirements of the first scenario. When the first button 150 is in the second state, the first microphone 120 and the second microphone 130 are both turned on, and the wireless headset 10 can be used in the second scenario. The second scene may be a scene used by multiple people, for example, a mini-conference, an interview, and the like.

Specifically, the battery 140 is electrically connected to the first microphone 120 through a first power supply circuit 160, so as to supply power to the first microphone 120 through the first power supply circuit 160. The battery 140 is electrically connected to the second microphone 130 through the second power supply circuit 170, so as to supply power to the second microphone 130 through the second power supply circuit 170.
