Description of drawings

Fig. 1 is for having the functional block diagram of the mobile phone of function of radio receiver in the embodiment of the invention.

Embodiment

Describe in further detail below in conjunction with the present invention of accompanying drawing embodiment.

Mobile phone with function of radio receiver provided by the invention, include the casing of mobile phone, the recording encoder functional module 4 that is installed in the interior communications electronics circuit of casing, mobile phone memory 1, handset earphone output port 2, FM FM reception module 3 and is connected with the output of this FM FM reception module, wherein, the communications electronics circuit includes the baseband processing chip 5 with D/A conversion functional module and decoding function module, and recording encoder functional module 4 links to each other with mobile phone memory 1, baseband processing chip 5 and handset earphone output port 2.Here, recording encoder functional module 4 is that the FM programme information that FM FM reception module receives is directly flowed to the handset earphone output port, the FM programme information that FM FM reception module is received carries out recording encoder simultaneously, and will be stored in the mobile phone memory through the FM programme information behind the coding, perhaps, read the FM programme information that is stored in the mobile phone memory, the FM programme information through coding that reads is sent to baseband processing chip decode, then decoded FM programme information is sent to the handset earphone output port.

In the present embodiment, mobile phone memory 1 is T-CARD commonly used, directly be connected with a handset earphone with handset earphone output port 2, recording encoder functional module 4 includes internal path selector switch, an A/D modular converter and the mp3 coding module of a control synchronization broadcast and playback function, FM FM reception module 3 adopts conventional FM FM reception module, and baseband processing chip 5 also adopts conventional baseband processing chip.

The mobile phone implementation method with function of radio receiver that present embodiment provides, it comprises the steps:

Like this, according to above-mentioned steps, the mobile phone that has function of radio receiver in the present embodiment can be realized three kinds of functions:

The FM programme information is play: choose synchronization to play passage the internal path selector switch, be input to the input left and right sides passage of recording encoder functional module 4 after the FM programme signal process FM FM reception module 3, output to the left and right acoustic channels of handset earphone output port then, carry out the synchronous broadcast of FM programme information.

The process of FM program synchronization is: after the FM programme signal is input to recording encoder functional module 4 via FM FM reception module 3, because the signal volume of recording is too big, so we need be to its processing of encoding, recording encoder functional module 4 has the function of coding, it includes A/D conversion, mp3 coding module.Signal after recording encoder functional module 4, except when putting through A/D converter, the digital signal after the conversion is compressed by the mp3 coding again, the file after the compression stores outside mobile phone memory T-card into by holding wire SD-Bus.

FM programme information replayed section: when the user needs playback, can give an order by operation, the internal path selector switch is chosen playback channels, the FM programme information of recording encoder functional module 4 beginning calling mobile phone memory T-card, arrive recording encoder functional module 4 by SD-Bus, be transferred to baseband processing chip 5 via holding wire SPI again, decoding function module and D/A modular converter by baseband processing chip 5 inside are converted to analog signal, output to the signal port MIC mouth of recording encoder functional module 4 again by holding wire EPPA mouth, output to the left and right acoustic channels of handset earphone output port then, like this, mobile phone provided by the invention just has the time-shifted of radio reception, it is the time-shift function, it can be according to the FM program in a period of time before the user's request playback, particularly can repeat to listen to excellent FM program and the program that has missed, the mobile phone that invention is provided has more practicality.
