In this experiment, we took apart an ancient cassette recorder. It was a fun and informing activity with disassembled parts to the point that we could examine the inner workings of its small electric motor. The input parts were a small microphone, a set of mechanical keys to control the cassette player and a cassette tape that could act as an input or output (if recorded on). There was not much processing going on here most of the board was dedicated to AC/DC power management and different output/input jacks, plus a sound volume. Outputs on this device consisted of the magnetic head for recording, speaker and headphones jack.
The most interesting parts to us were:
A. The head, a small magnetic read and write device that could act as an input or output.
B. The mechanical part that holds and runs the cassette tape. very sophisticated and delicate designed to work forever.
C. DC motor and how it works
D. Speaker, it is amazing how a simple cone can create such a variety of sounds.
