At 7, the sound is amplified to a desired volume, and reproduced and output from the headphones 8.

When the ID signal input to the reproduction control unit 4 is a limiting ID signal, the audio data to be reproduced and output from the audio signal storage unit 5 by the reproduction control unit 4 will be
Limited by the type of D signal (ID data value). That is, if a reproduction ID signal other than the reproduction enabled signal is received, a reproduction instruction of audio data corresponding to the reproduction ID signal is not output from the reproduction control unit 4, and accordingly, the audio signal storage unit No output reproduction from 5. Until the reproduction restriction is released by the restriction release ID signal, only the audio data corresponding to the reproduction ID signal set to be reproducible is reproduced and output from the audio signal storage unit 5 via the reproduction unit 6.

Here, the setting of the restriction ID signal for restricting the reproduction is performed by setting the reproduction ID signal for which the reproduction of the corresponding audio data is to be restricted or the data of the reproduction ID signal for enabling the reproduction of the corresponding audio data.
