This application provides a wireless headset, and relates to the field of TWS wireless headsets. The wireless headset includes a headset housing and a headset assembly accommodated in the headset housing. The headset assembly includes a microphone. The headset housing includes a bottom housing, the bottom housing includes a first bottom housing part and a second bottom housing part that are separated by using an insulating material, the first bottom housing part is a positive charging electrode, and the second bottom housing part is a negative charging electrode. A plurality of sound inlet holes are disposed on the bottom housing, and form microphone sound inlet channels communicating with each other. In the foregoing technical solutions, wind noise can be reduced, and call experience can be improved.

Wireless headset

A terminal device includes a processor, a direct stream digital (DSD) audio playback circuit, and a headset jack. The processor is connected to the DSD audio playback circuit, and the DSD audio playback circuit is connected to the headset jack. The processor outputs a DSD audio signal to the DSD audio playback circuit in response to triggering performed by a user. The DSD audio playback circuit is configured to process the DSD audio signal, generate an alert tone based on a current scenario, and superpose the processed DSD audio signal and the alert tone. The headset jack is configured to connect to a headset and play the superposed audio signal and alert tone using the headset.

Terminal device, and DSD audio playback circuit and method

A speaker includes a front cover, a coil, a frame, a magnet, a magnetic diaphragm, and a voice coil. The coil is located on an inner side of the front cover, the magnetic diaphragm is located between the coil and the voice coil, a periphery of the magnetic diaphragm is adhered to one side of the frame, the magnet is located on the other side of the frame, and the one side and the other side of the frame are two opposite sides of the frame. The voice coil is configured to drive the magnetic diaphragm to vibrate.

Speaker, terminal, and speaker control method

A terminal device includes: an access unit, connected between a headset or an audio speaker and a digital-to-analog converter, and configured for insertion of a detachable second power amplifier; a processor, configured to: detect whether the second power amplifier is inserted into the access unit, output a first digital signal when detecting that the second power amplifier is inserted, and output a second digital signal when detecting that the second power amplifier is not inserted; the digital-to-analog converter, connected to the processor, and configured to: when receiving the first digital signal, convert the first digital signal to a first analog signal, and send the first analog signal to the second power amplifier; and when receiving the second digital signal, convert the second digital signal to a second analog signal, and send the second analog signal to a first power amplifier.
