What is an acoustic coupler?(What is, Concept and Definition)

Popular in the 1970s, the acoustic coupler was a device that allowed a computer to connect to other computers using a telephone.The earliest acoustic couplers used a telephone and transmitted at speeds of up to 300 baud.To transmit information, the acoustic coupler converts the data into sound signals, sends those signals over the phone line, and then the receiving acoustic coupler interprets those signals.The image is an example of an acoustic coupler available through Konexx.

Today, data transmission over telephone lines is done through a modem instead of the acoustic coupler due to reliability, speed, and ease of use, although acoustic couplers are seldom used today, even They can be a solution for travelers who do not have access to a modem or network connection.
