The area is provided with the unit, is used for the area according to place of the present invention, for the FM regulon is selected corresponding adjustable FM frequency range.Because different regions FM frequency range is different; The device range that FM signal receives is also just different; For example: be: 87.5-108MHz and be 76-90MHz in Japanese FM frequency range in the FM of China frequency range; Make the present invention can adapt to the normal use in a plurality of areas, preferably set up an area unit is set; Certainly, in order to solve this technical problem, also can be with the adjustable expanded range of FM regulon, for example expand to: the ultra wide frequency ranges of 64-125MHZ.
Shown in Fig. 2 and Fig. 3; The certain elasticity of each frame tool of the present invention, before the use, at first the bottom with mobile phone 8 places in the frame of the present invention; The data line interface of its bottom is cooperated grafting with connection-peg 5, the top of mobile phone 8 is buckled in the present invention get final product then.When needing car audio system to play mobile phone music; Through handset starting FM signal transmitter module of the present invention; Set up broadcast receiver wireless connections with car audio system; Broadcast receiver is adjusted to the frequency corresponding with the FM signal transmitter module; Or broadcast receiver is adjusted to any idle channels, the tranmitting frequency through the FM signal transmitter module is regulated in the software controls in the mobile phone 8 makes it identical with the broadcast receiver frequency; Easy to use, break away from the constraint of connecting line.
Shown in Fig. 5 and Fig. 7, the regulatory process workflow in the mobile phone is following:
1) software startup is transferred regulatory process through the built-in menu of mobile phone, starts software;
2) detection accessory and connecting, the data line interface state of detection of handset bottom judges whether the connection-peg of mobile phone protective cover connects, if successful connection gets into next step, otherwise cycle detection;
3) connect with annex and with the annex synchrodata, that is to say with mobile phone protective cover in the FM signal transmitter module connect, carry out data sync to the control unit of FM signal transmitter module;
4) get into regulatory process master interface, as shown in Figure 7;
5) behind the entering regulatory process master interface, the user can operate as follows:
A, call the FM regulon and adjust the FM frequencies operations; Mode of operation can be to regulate tranmitting frequency through the adjustment disk Rapid Cycle in main interface, also can be through positive and negative arrow single step increase and decrease tranmitting frequency;
B, call memory cell and carry out storing frequencies, three channel buttons that prestore among Fig. 7 extract the data that prestore in individual palpation, the long state that prestores of revising that on time gets into, and short once more pressing, current tranmitting frequency is kept at the button positions that is pressed;
C, click the IPOD icon in the upper left corner, transfer the music player of embedded in mobile phone, carry out music control by the music control unit;
D, call the area and the unit is set carries out the area and be provided with, the correspondent frequency adjustable extent is set;
E, change emission state by switch control unit, the button in the upper right corner uses as emission switch, and every click once; Emission state takes place once to change; The disk at center is used to indicate emission state, shows green, exhibit red when closing when opening emission;
6) behind the each end of operation of user, interface state upgrades;
7) after getting into regulatory process master interface, state detection unit stops carrying out the detection accessory state, from the annex reading of data, that is to say whether the data line interface that detects FM signal transmitter module and mobile phone is in connection status; When detecting notconnect state, the prompting user will insert, and return wait and connect.
Shown in Fig. 6, the FM signal transmitter module part workflow in the mobile phone protective cover of the present invention is following:
A, power-up initializing MCU that is to say the control unit energising initialization of FM signal transmitter module;
B, initialization radio reception chip that is to say the transmitter unit initialization of FM signal transmitter module;
Whether c, detection IPhone insert, and that is to say whether the control unit detection connection-peg of FM signal transmitter module is connected with the data line interface of mobile phone;
The code signal that the control unit of d, FM signal transmitter module issues according to mobile phone carries out the authentication of IPhone accessory product, then, judges whether session opens; And judge whether the switch control unit in the regulatory process is opened; Open if judge session, emission switch is opened, and then gets into next step; Otherwise cycle detection is waited for;
The coding that the control unit of e, FM signal transmitter module issues according to mobile phone is regulated radio reception chip tranmitting frequency, and the audio signal of mobile phone is carried out tuning emission.
