Abstract: A point-to-multipoint data transmission method and device, the method including a left earbud and a right earbud of a true wireless stereo (TWS) headset separately performing pairing and service content negotiation with an electronic device. The left earbud receives left configuration information sent by the electronic device, to configure a left ISO channel, and the right earbud receives right configuration information sent by the electronic device, to configure a right ISO channel. The left earbud receives, based on the BLE-based audio profile, audio data that is sent by the electronic device through the left ISO channel, and the right earbud receives, based on the BLE-based audio profile, the audio data that is sent by the electronic device through the right ISO channel. The left earbud and the right earbud play the respectively received audio data based on a first timestamp.

Abstract: An audio data transmission method. An electronic device transmits audio data to a first earbud of a TWS headset by using a first CIS of a first CIG, and transmits audio data to a second earbud of the TWS headset by using a second CIS of the first CIG. The electronic device determines that the TWS headset is switched from a double-earbud mode (namely, a mode in which the first earbud and the second earbud are used together as audio input/output devices of the electronic device) to a first single-earbud mode (namely, a mode in which the first earbud is independently used as an audio input/output device of the electronic device). In response to the determining, the electronic device deactivates the second CIS, stops transmitting audio data to the second earbud by using the second CIS, and continues transmitting audio data to the first earbud by using the first CIS.

Abstract: Embodiments of this application disclose a noise reduction headset. A branch pipe is disposed in the headset to connect a sound cavity inside the headset and an external environment. The branch pipe has a low-pass filter function to filter out high-band noise entering the sound cavity from the external environment, so that impact on sound quality inside the sound cavity that is caused by noise in the external environment is reduced, thereby implementing passive noise reduction.

Abstract: Embodiments provide an ear pad having an annular structure. The ear pad includes an inner layer and an outer layer covering the inner layer. The inner layer and the outer layer are separate of annular structures and are separated by a first medium layer. The inner layer coats a second medium layer. Acoustic impedance of the first medium layer is different from acoustic impedance of the inner layer and the outer layer. The ear pad is configured to close a front cavity space between a housing and an ear of a user, thereby preventing sound leakage and reducing external noise entering the ear of the user. Various ear pad embodiments provide a double-layer structure including the inner layer and the outer layer separated by the first medium layer.

Abstract: An input method and a smart terminal device. After a processor in the smart terminal device determines, based on a first detection solution of a first infrared sensor, that a target object enters or leaves a first space range from a first plane, the processor starts or stops displaying a cursor based on distances measured by ultrasonic sensors; and after the processor determines, based on a second detection result of a second infrared sensor, that the target object enters or leaves a second space range from a second plane, the processor starts or stops performing a confirmation operation based on a location of the cursor.
