Abstract
A compact solid state representative communication device allows the user to record, transmit, receive, play and erase messages or sounds. The communication device includes a record switch for recording messages to be sent, a transmit switch for sending messages, a play switch for playing recorded and received messages, a microphone for converting sound waves into electrical signals indicative of sound waves, an audio recorder for recording and playing back electrical signals indicative of sound waves, a transmitter for transmitting electromagnetic signals (preferably but not necessarily IR signals) indicative of sound waves, a receiver for receiving electromagnetic signals indicative of sound waves and a speaker for converting electrical signals into sound waves, all encased in a single compact housing. The communication device is small enough and light enough to be worn on the clothing of a person.
