A wireless acoustic transmission device used in an acoustic offering service
having
superior convenience, includes wireless transmitter for transmitting the service
request signal to request the desired acoustic signal, a wireless receiver for
receiving the transmission signal containing the acoustic signal to be transmitted
in response to the service request signal, a demodulator and decoder for restoring
the acoustic signal applying the demodulation and/or decoding processing to the
receiving signal transmitted from the wireless receiver, and an electro-acoustic
transformer for transforming the acoustic signal restored by the demodulator and
decoder the radio waves and for outputting. Accordingly, the desired acoustic signal
can be easily obtained without having the recording medium on which the acoustic
signal is recorded, and the acoustic offering service having superior convenience
can be realized.
