Abstract: An electronic device includes an audio processing unit, a first-type array element, and a second-type array element. The audio processing unit is configured to: receive an initial audio signal, and determine a first-type audio signal and a second-type audio signal based on the initial audio signal, where the first-type audio signal includes M first audio signals, and the second-type audio signal includes N second audio signals. The audio processing unit is further configured to send the first-type audio signal to the first-type array element, and send the second-type audio signal to the second-type array element. The first-type array element is configured to output M first sound wave signals based on the corresponding first audio signals. The second-type array element is configured to output N second sound wave signals based on the corresponding second audio signals.

Abstract: A voice masking method, apparatus, and system are provided, which are applicable to the field of intelligent vehicles. The method includes: determining a voice source location and a target masking location; receiving a sound signal from the voice source location, and detecting whether a voice signal exists in the sound signal, to generate a detection result; and if the detection result is that the voice signal exists in the sound signal, generating a masking sound for the voice signal, and outputting the masking sound to a first speaker at the voice source location and a second speaker at the target masking location; or if the detection result is that no voice signal exists in the sound signal, skipping generating the masking sound. According to this application, a requirement of an occupant for private voice communication in vehicle cockpit space can be met, and information security can be improved.

Abstract: Embodiments of the present disclosure disclose a method and a system for switching a sound channel of a headset, and a headset terminal, to accurately identify and determine a left-ear wearing status and a right-ear wearing status of a headset terminal, and accurately send a left-channel input audio signal and a right-channel input audio signal. A user does not need to manually switch between a left channel and a right channel of the headset terminal. This greatly improves the convenience of using the headset terminal.
