US 2019/0098409 A1 · DIRECTIONAL SOUND PLAYING SYSTEM AND METHOD

Abstract

A directional sound playing system using ultrasonic sound sources, the ultrasonic sound sources being installed on a surface of a supporting body. The directional sound playing system includes a setting module, a first detecting module, and a driving control module. The setting module sets a distribution position of each of the ultrasonic sound sources on the surface of the supporting body according to the angle of output of each of the ultrasonic sound sources and a requirement angle of a listener. The first detecting module obtains location information of the listener. The driving control module selects and drives one or more ultrasonic sound sources to transmit and direct ultrasonic sound corresponding to the location information of the listener. A directional sound playing method is also provided.

Dependent claims

A directional sound playing method comprising:

setting an orientation for distribution by a plurality of ultrasonic sound sources on a surface of a supporting body by a setting module according to a covering angle of the ultrasonic sound sources and a requirement angle of a receiver;
obtaining location information of the receiver by a first detecting module;
selecting and driving one or more ultrasonic sound sources to transmit ultrasonic sound to correspond to the location information of the receiver by the driving control module;
detecting a sport mode of the supporting body by a second detecting module;
and
updating the location information of the receiver at a predetermine interval by the second detecting module, wherein each of the sport modes correspond to a different predetermine interval.
