The display window 11 which displays a broadcasting station frequency, and the speaker 13 which outputs the audio signal converted by the digital receiving process part 10 are comprised.

Referring to the accompanying drawings, the operation of the mobile communication terminal and the radio receiver according to the related art as described above are as follows.

First, in the case of reception, the mobile communication terminal receives the radio frequency signal transmitted from the base station at the communication antenna 1.

The received radio frequency signal is appropriately modulated by the radio frequency transceiver 2 under the control of the digital communication processor 3, and then transmitted to the digital communication processor 3, and the digital communication processor 3 receives a voice signal that can be heard by the user. Is converted to the speaker (7).

In the case of transmission, when the user presses the telephone number with the key input unit 5, the telephone number is displayed on the display window 4 under the control of the digital communication processing unit 3, and the signal corresponding to the telephone number is transmitted to the radio frequency transceiver unit 2 In this case, the signal is transmitted to the base station through the communication antenna 1.

Send it out.

On the other hand, since the radio receiver performs only a reception operation, when a user selects a desired broadcasting station frequency using the tuner unit 12, the broadcasting station frequency is displayed on the display window 11 under the control of the digital receiving processing unit 10 and transmitted from the broadcasting station. The broadcast signal is transmitted to the radio frequency receiver 9 through the radio receiving antenna 8.

The signal of the radio frequency receiver 9 is appropriately modulated to the desired broadcast signal under the control of the digital reception processor 10 and then transmitted to the digital reception processor 10, and the digital reception processor 10 is a voice signal that can be heard by the user. It is converted and delivered to the speaker 13.

As described above, since a mobile communication terminal and a radio receiver are configured in separate forms, a separate purchase cost is required because the mobile communication terminal and the radio receiver have to be separately purchased, and there is a disadvantage in that it is inconvenient to carry when climbing or traveling.

In addition, when listening to the radio through the communication line of the mobile communication terminal to listen to the radio broadcast in the form of a telephone call using a phone number specified by each mobile communication service provider has a disadvantage of paying a separate telephone fee.

An object of the present invention is to solve the above problems, it is to provide a radio receiver in the mobile communication terminal to listen to the radio broadcast on the mobile communication terminal itself without going through the communication line of the telephone call type.

A feature of the present invention for achieving the above object, because the mobile communication terminal has a built-in radio receiver, there is no need to spend a separate radio receiver purchase, because the radio is added to the mechanical parts rather than the connection of the radio It is possible to save the telephone fee paid by listening.

In addition, since the mobile communication frequency (770 to 960 MHz, 1.7 to 2 GHz) and the radio reception frequency (AM for 530 to 1600 GHz and FM for 88 to 108 MHz) are different, the radios of the communication antenna, the radio receiving antenna and the mobile communication terminal are different. It is possible to separately configure the frequency transceiver and the radio receiver of the radio receiver, to operate the tuner of the radio receiver as a key input unit of the mobile communication terminal, and to share the digital processing unit of the mobile communication terminal and the radio receiver.
