Abstract

A system for providing magnetic field audio signals to a receiver in an aquatic environment. The system includes an audio source configured to provide an electronic audio signal, and an induction loop amplifier configured to receive the electronic audio signal and convert the received electronic audio signal into a current. The system further includes a wire loop connected with the induction loop amplifier, the wire loop bounding at least part of the aquatic environment and around the receiver in the aquatic environment, the wire loop producing a magnetic field from the current to generate an audio frequency induction loop to transmit the electronic audio signal to the receiver in the aquatic environment.

Claims (7)

1 . A system for providing audio signals to an aquatic environment from an audio source configured to provide the audio signals, the system comprising:

an induction loop amplifier configured to receive the audio signals from the audio source and convert the received audio signals into a current; and

a wire loop connected with the induction loop amplifier, the wire loop being configured to circumscribe at least part of the aquatic environment and around a receiver in the aquatic environment within the wire loop, the wire loop producing a magnetic field from the current to generate an audio frequency induction loop to transmit the electronic audio signal to the receiver in the aquatic environment.

2 . The system in accordance with claim 1 , wherein the induction loop amplifier is connected to opposite ends of the wire loop.

3 . The system in accordance with claim 1 , wherein the system includes a plurality of wire loops, and wherein the induction loop amplifier includes a plurality of outputs, each output being connected to one of the plurality of wire loops.

4 . The system in accordance with claim 1 , wherein the receiver includes waterproof headphones.

5 . The system in accordance with claim 4 , wherein the receiver is configured to be worn by a person in the at least part of the aquatic environment within the wire loop.
