Title:
DIRECTIONAL BROADCASTING METHOD, APPARATUS, HOUSEHOLD APPLIANCE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/015297
Kind Code:
A1
Abstract:
Provided in the present disclosure are a directional broadcasting method, an apparatus, a household appliance, and a computer readable storage medium, the directional broadcasting method comprising: acquiring orientation information of an object to be directed; loading an audio signal into a high-frequency signal to obtain a modulation signal; and broadcasting the modulation signal to the object to be directed. Since a high-frequency signal has the feature of directional propagation, modulating an audio signal into a high-frequency signal for transmission achieves directional transmission in the air, and auto-demodulation is finally achieved in the air such that the ears may hear a reduced audio signal, thereby solving the problem of targetedly performing voice directional propagation according to the position at which a user is located.
