Patent ID: 8391502

Claim:
A sound reproducing apparatus comprising: a signal receiver configured to receive an audio signal generated by an audio signal generating apparatus; a first signal transmitter configured to transmit the received audio signal to an audio output apparatus which is connected to the sound reproducing apparatus; a second signal transmitter configured to transmit the received audio signal to a speaker which is connected to the sound reproducing apparatus; a power supply unit configured (i) to provide power to the first signal transmitter in both a power stand-by state of the sound reproducing apparatus and a power-on state of the sound reproducing apparatus and (ii) to provide power to the second signal transmitter in the power-on state and to not provide power to the second signal transmitter in the power stand-by state; a data storage unit configured to store reproducibility information of the sound reproducing apparatus, the reproducibility information of the sound reproducing apparatus for being selectively used by the audio signal generating apparatus to generate the audio signal; a data obtaining unit configured to obtain reproducibility information of the audio output apparatus, the reproducibility information of the audio output apparatus being selectively used to generate the audio signal by the audio signal generating apparatus; a state switching unit configured to switch the sound reproducing apparatus between the power stand-by state or the power-on state; a control unit configured to switch output designations in response to the state switching unit switching the sound reproducing apparatus to one of the power stand-by state or the power-on state, independently of detection of any connection state of the sound reproducing apparatus with either the audio output apparatus or the speaker, and to select the reproducibility information of the sound reproducing apparatus or the audio output apparatus based on the output designation which the control unit switches to, to send the selected reproducibility information to the audio signal generating apparatus, wherein: if the output designation, to which the control unit switches, is the speaker, the control unit selects the reproducibility information of the sound reproducing apparatus to send to the audio signal generating apparatus, if the output designation, to which the control unit switches, is the audio output apparatus, the control unit selects the reproducibility information of the audio output apparatus to send to the audio signal generating apparatus, in response to the sound reproducing apparatus being switched by the state switching unit to the power stand-by state, the control unit switches the output designation to the audio output apparatus, and in response to the sound reproducing apparatus being switched by the state switching unit to the power-on state, the control unit switches the output designation to the speaker and controls the first signal transmitter to not provide the received audio signal to the audio output apparatus.
