Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle-mounted acoustic apparatus having a plurality of keys and a display arranged in parallel near the keys.

[0002]

2. Description of the Related Art For example, a recent vehicle-mounted audio device which is capable of radio reception, tape reproduction, disk reproduction, and the like has been further miniaturized, but required functions have increased. There is. However, because the size of the device is restricted, the operation buttons (keys) are proportionate to the functions.
It is impossible to increase the number of. For this reason, generally, a method in which one type of key is also used is adopted. For example, by using a radio reception key that is not used during tape playback, also during tape playback, one type of key can be used for both tape playback and radio reception, thus providing multiple functions. That's the method.

However, in the case where one type of key is also used to have a plurality of functions in this way, it is necessary to provide, by printing or the like, indications, marks or the like indicating the plurality of functions to be used respectively on the body of the key. Therefore, there is an inconvenience that the design of the key becomes complicated.

In Europe, AD by FM multiplex broadcasting
i and RDS are widely used, and traffic information and broadcast programs (PTY: Program Type) arbitrarily selected by the user are available.
The interrupt e) is configured to function in modes other than radio reception. Therefore, when the user wants to listen to the traffic information even during tape reproduction or disc reproduction other than radio reception, the user can preferentially listen by selecting a traffic information program.

[0005]

By the way, in the conventional on-vehicle audio system, one kind of key is also used when an arbitrary program such as traffic information is desired to be preferentially listened to except when receiving radio. If a plurality of functions are provided, the operability is lowered, so that there is a problem that an erroneous operation is likely to occur.

The present invention has been made in consideration of the above problems, and improves operability and avoids erroneous operation when an arbitrary program such as traffic information is selected and preferentially listened to. It is an object of the present invention to provide a vehicle-mounted acoustic device as described above.

[0007]

In order to achieve the above object, the present invention according to claim 1 is provided with a plurality of keys and a display juxtaposed in the immediate vicinity of the keys, each of which corresponds to each mode. A display control means for switching and displaying the function of the key at a corresponding position on the display, wherein the display control means is in the reception interrupt mode of the predetermined information, among the display areas of the display corresponding to the respective keys, It is characterized by comprising first means for turning off the display of the area corresponding to the key not related to the reception of the predetermined information.

[0008]

According to the structure of the present invention according to claim 1, the display switching means for switching and displaying the functions of the plurality of keys at the corresponding positions of the display according to each mode is for receiving an arbitrary program such as traffic information. During the interrupt mode, it operates so as to turn off the display of the area corresponding to the key not related to the reception of any program such as traffic information among the display areas of the display corresponding to the above keys. As a result, when an arbitrary program such as traffic information is selected and desired to be preferentially listened to, operability can be improved and erroneous operation can be avoided.

According to this embodiment as described above, the AM
The PTY interrupt standby state of traffic information and RDS can be set except when the broadcast is received. When the reception interrupt mode of any program such as traffic information is set, the display 2 corresponding to each key 1b to 1g is displayed. Of the display areas 2b to 2g,
Areas corresponding to keys not related to reception of arbitrary programs such as traffic information are turned off. Therefore, it is possible to understand that only the key corresponding to the area of the display 2 that is lit in the reception interrupt mode of the traffic information etc. is related to the reception of the arbitrary program such as the traffic information. When a traffic information program or the like is selected and desired to be preferentially listened to, operability can be improved, and thus erroneous operation can be avoided.

In the embodiment of the present text, the mode provided in the vehicle-mounted audio device has been described as a limited example. However, the present invention is not limited to this, and is not limited to other vehicle-mounted audio devices having an arbitrary mode. However, the same can be applied.
