DIY Laser Wireless Audio Transmission Circuit Kit for Electronic Experiment Welding Learning

Product Information

Voltage:9VDC

Circuit Size:Emitter Circuit: 40*22mm

                     Receiver Circuit:26*20mm

Function Description

It can transmit long-distance and one-way calls (Duplex intercom need to purchase 2 sets of the product ) or transmit audio signals such as mobile phone mp3, and receive audio signals at the receiving end. The basic principle of using infrared laser sound transmission is to convert fluctuating sound into red laser light, then the laser vibration signal is received in the photodiode receiver of the receiver circuit, and the signal is demodulated to achieve sound restoration. The transmission distance can reach 50 -100 meters and can be used to make long-distance wireless loudspeakers.

Product Parameter

1. Input: 3.5 audio input (computer, mobile phone, MP3, etc.)

2. Transmission distance: It is recommended to be within 50-100 meters, the farther the distance, the more erratic the signal.

3. The working voltage of the receiver:4-12V.

4. Loudpeaker Power: 0.5W-10W.
