Abstract

One aspect of the present invention can include a playback device capable of externally receiving a playback signal for playing back a sound or an image, and capable of transmitting the playback signal to the playback device if it is detected that a predetermined electric source was externally supplied.

Claims

1. A playback control apparatus which can be electrically connected with a playback device capable of externally receiving a playback signal for playing back a sound or an image, and which transmits the playback signal to the playback device if it is detected that a predetermined electric source was externally supplied to itself.

2. The playback control apparatus according to claim 1, wherein the connected playback device includes a storage medium for storing the sound as a playback object.

3. The playback control apparatus according to claim 2, wherein:

the apparatus has a plug which can be connected with an electric source supply part capable of supplying an electric source to an inside or an outside of a vehicle, and

the predetermined electric source is supplied from the electric source supply part through the plug as an operation for starting an engine of the vehicle is performed.

4. The playback control apparatus according to claim 3, wherein the apparatus includes a switch capable of switching an operation state to either ON or OFF and, only when the operation state of the switch is ON, the playback signal is transmitted to the playback device.

5. An audio system for outputting a sound or an image, which is played back by a playback device, from a speaker or a display provided externally of the playback device, wherein:

the playback device is constituted so as to be capable of externally receiving a playback signal for playing back the sound or the image, and

the system has a playback control apparatus which can be electrically connected with the display device, and transmits the playback signal to the playback device if it is detected that a predetermined electric source was externally supplied to itself.

6. A playback control apparatus comprising an adapter capable of transmitting a playback signal to a playback device if it is detected that a predetermined electric source was externally supplied to the adapter.

7. The playback control apparatus according to claim 6, wherein the playback device includes a storage medium for storing the sound as a playback object.

8. The playback control apparatus according to claim 7, wherein:

the adapter includes a plug which can be connected with an electric source supply part capable of supplying an electric source, and

the predetermined electric source is supplied from the electric source supply part through the plug based on starting an engine of a vehicle.

9. The playback control apparatus according to claim 8, wherein the adapter includes a switch capable of switching an operation state to ON and OFF, wherein when the operation state of the switch is ON, the playback signal is transmitted to the playback device.

10. An audio system for outputting a sound or an image comprising:

a playback device capable of outputting a sound or image from at least one of a speaker or a display, wherein;

the playback device is capable of externally receiving a playback signal for playing back the sound or the image, and

the system has a playback control apparatus which can be electrically connected with the display device, and transmits the playback signal to the playback device if it is detected that a predetermined electric source was externally supplied to itself.
