Abstract

The present invention provides a directional broadcast method and device, a home appliance, and a computer readable storage medium, wherein the directional broadcast method includes: acquiring the orientation information of an object to be oriented: loading an audio signal into a high-frequency signal to obtain a modulated signal; and broadcasting the modulated signal to the object to be oriented.Since the high-frequency signal has the characteristics of directional propagation, the modulation of the audio signal into the high-frequency signal enables directional transmission in the air and finally achieves self-demodulation in the air. Thus, human ears can hear a restored audio signal. Therefore, the problem in the prior art is solved that the voice directional propagation cannot be achieved according to the location of a user.

Description

technical field [0001] The present invention relates to the technical field of audio transmission, in particular to a directional broadcast method, device, household appliance and computer-readable storage medium. Background technique [0002] Existing voice broadcasts mostly use traditional speakers to output sound. Traditional speakers cannot effectively control the direction and area of ​​sound transmission. When there are multiple users, it may affect users who do not want to hear the voice announcement. [0003] At present, the common method of voice directional broadcast is a method such as that used in directional sound transmission televisions. The directional sound transmission is to control the sound reversal through sound insulation materials or speaker arrays, and to control the sound propagation direction physically. This method Restricting the direction of the sound can only be heard by the user in cooperation with the relevant area of ​​the device, rather tha...
