Abstract

A vehicle audio adapter which is used in a vehicle multivision system in which electronic apparatuses including an audio, television, car navigation, air condition control, picture monitor and switch panel are connected by a LAN cable to be constructed into a room LAN so that the electronic apparatuses are intensively controlled by a single monitor. When a predetermined one of the electronic apparatuses connected by the room LAN cable is replaced with a non-genuine apparatus which cannot be connected by the room LAN cable and is unsuitable for the room LAN, functions of the room LAN are maintained with the genuine apparatus being left and the genuine apparatus is replaceable with the non-genuine apparatus.

Claims

1. A vehicle audio adapter which is used in a vehicle multivision system in which electronic apparatuses including an audio, television, car navigation, air condition control, picture monitor and switch panel are connected by a LAN cable thereby to be constructed into a room LAN so that the electronic apparatuses are intensively controlled by a single monitor, wherein when a predetermined one of the electronic apparatuses connected by the room LAN cable is replaced with a non-genuine apparatus which cannot be connected by the room LAN cable and is unsuitable for the room LAN, functions of the room LAN are maintained with the genuine apparatus being left and the genuine apparatus is replaceable with the non-genuine apparatus.

2. A vehicle audio adapter according to claim 1, wherein an apparatus necessary for the room LAN is moved from one position to another in the vehicle and which further comprises a fitting for mounting the non-genuine apparatus instead of the moved room LAN.

3. A vehicle audio adapter according to claim 1, wherein the non-genuine apparatus added at another position in the interior of the vehicle can be replaced without moving an apparatus necessary for the room LAN.

4. A vehicle audio adapter according to claim 1, further comprising a signal wire provided for connecting a LAN cable or extension cable required for moving the apparatus necessary for the room LAN.

5. A vehicle audio adapter according to claim 4, wherein a sound signal circuit is connected only when the non-genuine apparatus is turned on, using an external amplifier remote signal changing to 12 V when the non-genuine apparatus is turned on and to 0 V when the non-genuine apparatus is turned off.

6. A vehicle audio adapter according to claim 5, further comprising a double-throw switch with a plurality of poles or relay switch for switching the sound signal circuit between the genuine audio apparatus and a non-genuine audio apparatus.

7. A vehicle audio adapter according to claim 1, wherein another location in the vehicle to which an apparatus required for the room LAN is moved includes an interior of a glove box, a space under a seat, an interior of a trunk, a luggage space and the like, the adapter further comprising fittings for fixing the apparatus at said another location.

8. A vehicle audio adapter according to claim 2, wherein another location in the vehicle to which an apparatus required for the room LAN is moved includes an interior of a glove box, a space under a seat, an interior of a trunk, a luggage space and the like, the adapter further comprising fittings for fixing the apparatus at said another location.

9. A vehicle audio adapter according to claim 3, wherein another location in the vehicle to which an apparatus required for the room LAN is moved includes an interior of a glove box, a space under a seat, an interior of a trunk, a luggage space and the like, the adapter further comprising fittings for fixing the apparatus at said another location.

10. A vehicle audio adapter according to claim 4, wherein another location in the vehicle to which an apparatus required for the room LAN is moved includes an interior of a glove box, a space under a seat, an interior of a trunk, a luggage space and the like, the adapter further comprising fittings for fixing the apparatus at said another location.

11. A vehicle audio adapter according to claim 5, wherein another location in the vehicle to which an apparatus required for the room LAN is moved includes an interior of a glove box, a space under a seat, an interior of a trunk, a luggage space and the like, the adapter further comprising fittings for fixing the apparatus at said another location.

12. A vehicle audio adapter according to claim 6, wherein another location in the vehicle to which an apparatus required for the room LAN is moved includes an interior of a glove box, a space under a seat, an interior of a trunk, a luggage space and the like, the adapter further comprising fittings for fixing the apparatus at said another location.
