Modular Design of Short-Distance Wireless Audio Transmission System

This article designs a short-distance wireless transmission system for audio signals based on infra-red light communication, using infrared light emitting diodes and infrared light receiving modules as transmitting and receiving devices. Within a transmission distance of 1 m, the short-distance wireless transmission of audio signals is achieved. The system is different from previous chip modules based on relatively fixed parameters and functions, but adopts a discrete modular design. The functional modules of the transmitting and receiving components are independent and inter-connected, allowing for convenient module replacement and re-configurable technology updates and upgrades under the conditions of functional implementation.
