DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
The invention relates to a radio receiver in accordance with the species of the main claims.
A motor vehicle communications center is known from DE 40 09 899 C1, which is used for the common operation of a car telephone and a car radio. The motor vehicle communications center comprises further connections for devices being used in the interior of the motor vehicle. When receiving a telephone call, the remaining devices connected with the center are automatically switched off by the cradle switch. When lifting the receiver of the car telephone, all sources of interfering noise are switched off the moment it is lifted off, and are only switched on again when the receiver is put down. In this connection the car radio is also considered as a source of interfering noise.
ADVANTAGES OF THE INVENTION
In contrast to this, the radio receiver with the characteristics of independent claim 1 has the advantage that it is not necessary to switch all speakers to telephone reception during telephone operations, but the simultaneous radio reception and telephone reception via the loudspeakers is possible instead. In this way, during telephone operation the user does not lose information sent by radio at the same time.
It is furthermore advantageous that the partial switching of the loudspeaker to radio reception takes place automatically as the function of the reception of a preset signal by means of the radio receiver. It is possible in this way to limit the partial switching of the loudspeaker to radio reception to those cases in which particularly important information is broadcast by radio and is therefore recognized by an identifying signals. In this way the telephone operation is only "interfered with" in case of particularly important information broadcast by radio.
A further advantage lies in that switching takes place automatically, by which the operation of the radio receiver is considerably simplified.
An advantageous further development and improvement of the radio receiver disclosed in independent claim 1 is possible by the step mentioned in dependent claim 2.
Switching as a function of the detection of an identifying signal regarding traffic information is advantageous here. When using the radio receiver in a motor vehicle, the user is informed in this way of the actual traffic conditions even when operating the telephone.
The radio receiver in accordance with the invention having the features of independent claim 3 has the advantage that, in case of a loop allocation during radio receiving operations, 4 loudspeakers are switched at least partially to telephone reception. In this way the user can simultaneously listen to the radio and use the telephone. In addition, here, too, the advantage of automatic switching leads to a considerable simplification of the operation of the radio receiver. The advantage of switching all loudspeakers in case of a loop allocation resides in that the telephone operation is not "interfered with" by the radio reception, wherein the user himself need not switch off the radio reception.
Advantageous further developments and improvements of the radio receiver disclosed in independent claims 1 and 2 are possible by the steps mentioned in dependent claims 4 to 6.
In accordance with claim 4, it is advantageous that different preset allocations of telephone and radio signals to the loudspeakers can be switched in. A variable assignment of the telephone and radio signals to the different loudspeakers is possible in this way and can be individually selected by the user.
It is furthermore advantageous that, following a selection of a preset allocation, a switching process can be initiated by means of an operating unit. In this way the user can switch around a set assignment of the telephone and radio signals to the respective loudspeakers in accordance with his requests.
