Abstract

The invention discloses a directional audio source broadcasting system based on UWB, belongs to the technical field of automation and solves the problem that in the prior art, a directional audio transmission technology is poor in directionality and a target adjustment direction cannot be automatically tracked. The system comprises a UWB positioning module which is used for tracking a moving target in real time; an information processing module which is used for processing tracking information of the UWB positioning module; an ultrasonic transmitting module which is used for modulating an audio source signal to ultrasonic for transmission; and a digital electric holder which is used for receiving processing information of the information processing module and carrying out rotation control over the ultrasonic transmitting module on the holder. The system is used for directional audio broadcasting.

Description

Technical field [0001] A directional audio source broadcasting system based on UWB, used for directional audio broadcasting, belongs to the field of automation technology. Background technique [0002] Two problems need to be solved for sound directional transmission: 1. How to form an audio signal with directivity characteristics; 2. How to make sound waves point to an automatic tracking target. [0003] When private transmission of sound to a specific target is required in public places such as the street or conference room, the common way is to transmit through wireless communication, and the receiver will listen to the sound through headphones after receiving it. Ultrasonic transmission is adopted, which has the characteristics of good directivity, and is suitable for directional audio broadcast to the target. To ensure the directional effect when the system is working, the transmitter needs to move synchronously with the target to ensure that the audio directional direction is...
