摘要： Embodiments of this application provide a data stream transmission method, a device, a communication apparatus, and a storage medium. The method includes: sending a first target signal; obtaining a first moment, where the first moment is obtained based on a time point at which a first receiving device on a second device receives the first target signal; obtaining a second moment, where the second moment is obtained based on a time point at which a second receiving device on the second device receives the first target signal, where the first receiving device and the second receiving device are located at different positions of the second device, and the second device is a head-mounted device; and when determining, based on the first moment and the second moment, that a data transmission condition is met, transmitting a target data stream to the second device. Embodiments of this application help improve precision of data stream transmission between a first device and the second device.

摘要： A method and an apparatus (1600) for detecting a relative location between devices is disclosed. The detection method includes: obtaining a first target audio signal obtained by a first microphone of a device B (S701); determining a first audio segment and a second audio segment based on a first target moment and the first target audio signal, where the first target moment is a moment determined in the first target audio signal based on a target amplitude (S702); separately searching for the first audio segment and the second audio segment to obtain a first arrival moment and a second arrival moment (S703); and determining a relative location between a device A and the device B based on the first arrival moment and the second arrival moment (S704). Therefore, the relative location between the devices can be determined with high precision.

摘要： A data processing method and a related device are provided. The method can be used in the field of smart headsets. One headset includes two target earbuds, and the method includes: obtaining a first feedback signal corresponding to a first sounding signal, where the first sounding signal is an audio signal transmitted by using the target earbud, a frequency band of the first sounding signal is 8 kHz to 20 kHz, and the first feedback signal includes a reflected signal corresponding to the first sounding signal; and when it is detected that the headset is worn, determining, based on the first feedback signal, a first detection result corresponding to the target earbud, where the first detection result indicates that the target earbud is worn on a left ear or a right ear. An actual wearing status of each target earbud is detected according to an acoustic principle, in other words, a user does not need to view a mark on the earbud. This simplifies an operation of the user. In addition, no additional hardware is required, and manufacturing costs are reduced.
