Patent abstract
A two way communication system that does not require the use of a device by one of the communicators. The system employs an audio spotlight to project a signal to a specific location, where one person is, and a laser audio receiver to receive the response. Both the audio spotlight and the laser audio receiver are directed by a user seeking to communicate with the person at long range.
