Abstract
A speaker device includes an electroacoustic transducer configured to convert an audio signal into a set of sound waves and a transmitter configured to transmit an electromagnetic signal that carries the audio signal for receipt at distances limited to an audibility range of the set of sound waves. The audibility range of the set of sound waves corresponds to a distance at which the set of sound waves is estimated to be below a predetermined sound level.
