Cassette tape adaptor
From Wikipedia, the free encyclopedia
The cassette adapter was invented to allow one to play music through sound systems with a tape player but no auxiliary input. It consists of a 'dummy' tape that contains a tape head in the place where the tape player normally reads the tape. The head is then connected to a wire going out the side of the tape enclosure which usually has a male Jack plug on the end. [1]
This can then be plugged into a portable audio player such as a Minidisc, CD or MP3 player. This is useful in older cars without CD changers, as many vehicles sold have a cassette player but no facility to play back these other formats. One can use their current device with the cassette deck, negating the need to purchase another digital audio player.
