Description

A kind of mobile phone with intercommunication function
Technical field
The utility model relates to mobile phone, particularly a kind of mobile phone with intercommunication function.
Background technology
Existing mobile phone communication process need realizes that by mobile communications network wherein mobile communications network is generally all provided by Virtual network operator, so mobile phone needs to pay cost of the phone call in communication process.
Can adopt mobile communications network to realize for remote conversation, and can adopt intercom to realize for closely conversing, but generally, the personal user can not carry intercom, therefore can only adopt mobile phone to converse, will cause the waste of resource like this.
And the mobile phone of at present common band intercommunication function substantially all is based on GPRS network to realize, is realized by pure software in other words conj.or perhaps, belongs to the value-added service category of mobile phone.Though this kind mode can realize the intercommunication in the whole network, shortcoming also clearly: need payment GPRS exclusive monthly fee usefulness, the network coverage less than the place then can't converse.Another kind of mobile phone based on hard-wired band intercommunication function can not realize that still intercom telescopic antenna and mobile phone FM telescopic antenna are shared, particularly can not be implemented under the situation of not using the intercom telescopic antenna and carry out intercommunication by handset earphone.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of mobile phone with intercommunication function, and this mobile phone has realized that intercom telescopic antenna and mobile phone FM telescopic antenna are shared, and carries out intercommunication by handset earphone under the situation of not using the intercom telescopic antenna.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of mobile phone with intercommunication function, comprise mobile phone body, be installed in the mobile phone main circuit board in the mobile phone body, described mobile phone main circuit board is provided with the mobile phone main control chip, also be provided with intercom receiver module, intercom transmitter module, mobile phone radio frequency module, handset audio module and analog switch on the mobile phone main circuit board, described intercom receiver module, intercom transmitter module are connected with the mobile phone main control chip; Described mobile phone main control chip is connected with analog switch by the handset audio module, and described analog switch is connected with the intercom transmitter module.
Also be provided with antenna on the wherein said mobile phone body, this antenna is connected with mobile phone radio frequency module, intercom receiver module, intercom transmitter module respectively by band pass filter.
Also be provided with the FM module on the wherein said mobile phone main circuit board, described FM module is connected with the mobile phone main control chip.
The utility model is arranged on intercom reception, transmitter module on the mobile phone main circuit board, and the audio frequency radiating circuit of shared mobile phone, receiving circuit are realized the fully control of mobile phone main control chip to each module of intercom, realize functions such as emission, reception and standby.Compared with prior art, intercom telescopic antenna of the present utility model and FM telescopic antenna are shared, can realize that mobile phone FM function is issued in the situation of external earphone antenna not puts outside high-quality, and carries out intercommunication by handset earphone under the situation of not using the intercom telescopic antenna.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a theory diagram of the present utility model.
Embodiment
The utility model is by being arranged on intercom receiver module, transmitter module on the mobile phone main circuit board, the audio frequency radiating circuit of shared mobile phone, receiving circuit, realize of the fully control of mobile phone main control chip, realize functions such as emission, reception and standby each module of intercom.
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also Fig. 1, shown in Figure 2, the utility model provides a kind of mobile phone with intercommunication function, comprises mobile phone body 1, is installed in the mobile phone main circuit board in the mobile phone body and is arranged on antenna 2 on the mobile phone body 1.
Wherein the mobile phone main circuit board is provided with the mobile phone main control chip, intercom receiver module, intercom transmitter module, mobile phone radio frequency module, handset audio module, FM module and analog switch, described intercom receiver module, intercom transmitter module are connected with the mobile phone main control chip, and be connected with antenna by band pass filter BPF, and say and also be connected with VCO, IF and PLL module between machine receiver module, the intercom transmitter module.
The mobile phone main control chip is connected with analog switch by the handset audio module, and described analog switch is connected with outside MIC, earphone and loud speaker SPEAKER, and wherein earphone can be directly connected to antenna.
Analog switch is connected with the intercom transmitter module, and the mobile phone main control chip is connected with antenna by FM module, band pass filter BPF.
More than circuit module block diagram of the present utility model is introduced, will receive the utility model intercom below, each module operation principle in the emission course of work is described.
After at first entering the intercom pattern, VCO (voltage-control oscillator module), IF transceiver module and the PLL module of mobile phone main control chip control intercom provide the reference frequency and the modulation signal of intercom work.
Receiving mode, enter receive path behind the antenna receiving signal process band pass filter BPF, the mobile phone main control chip is then controlled intercom receiver module circuit and is opened, carry out down-conversion at mixting circuit and be reduced into voice signal, send into the handset audio circuit, after signal filtering is amplified, give loud speaker SPEAKER and play.
Emission mode, the MIC collected sound signal is directly sent into the intercom transmitter module by analog switch, and baseband I C control this moment intercom radiating circuit is opened, and carries out sending in advance after the up-conversion putting, and is launched by antenna then.
FM telescopic antenna and intercom telescopic antenna shared before FM IC and intercom module, designs corresponding BPF circuit respectively, avoids two phase mutual interference between system.
The realization of earphone intercommunication function, the handset earphone ground wire is linked to each other with the intercom antenna, carry out certain circuit design, make it become the intercom antenna, and in voicefrequency circuit, increase analog switch, the corresponding GPIO control program of software programming is controlled analog switch, need not extract the intercom antenna under the intercom pattern and just can make handset earphone become the intercom earphone thereby be implemented in.
More than a kind of mobile phone with intercommunication function provided by the utility model is described in detail, used specific case herein principle of the present utility model and execution mode are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
