Embodiment
Below in conjunction with accompanying drawing and preferred a kind of embodiment structure of the present invention is done explanation further:
Shown in Fig. 1, Fig. 2 and Fig. 3, the present invention is made up of mobile phone protective cover and 8 two parts of mobile phone.The main part of mobile phone protective cover mainly is made up of left frame 1,left frame 2,upper side frame 3 and lower frame 4.On the medial surface of describedlower frame 4, be provided with and cooperate the connection-peg 5 of pegging graft with the data in mobile phone line interface, this connection-peg 5 preferably with the matching used 514S0117 type of iPhone4 series mobile phone connector.Inlower frame 4, be provided with a FM signal transmitter module.
Shown in Fig. 4, this FM signal transmitter module includes a frequency modulation transmitter unit 6 and a control unit 7.Frequency modulation transmitter unit 6 is used to connect the audio output of the left and right sound channels of mobile phone; Convert the audio signal of mobile phone to FM signal and be sent to the FM signal receiving equipment; As: the home audio system of vehicle-mounted radio, band radio function etc., the model that this frequency modulation transmitter unit 6 adopts is: QN8027FM transmitting chip U1; Control unit 7 is used to connect the control signal output ends of mobile phone, and the frequency adjustment control signal that issues according to mobile phone is regulated the tranmitting frequency of the FM signal of frequency modulation transmitter unit 6.This control unit 7 adopts a model to be: the chip U2 of C8051F300.The power input of described frequency modulation transmitter unit 6 and control unit 7 is connected the power output end of mobile phone through connection-peg 5, obtains the working power of a 3V from mobile phone.Be connected with data communication between computer in order not influence mobile phone, be connected with mini USB interface J2 on the connection-peg 5.
Describedmobile phone 8 is located in this mobile phone protective cover, and the bottom ofmobile phone 8 is provided with data line interface, music player and regulatory process and regulatory process in installing in the mobile phone 8.The effect of described regulatory process is the tranmitting frequency that is used to regulate the FM signal of controlling the FM signal transmitter module.This regulatory process includes: a FM regulon, a music control unit, a switch control unit, a memory cell, a state detection unit and area are provided with the unit.
The FM regulon; Be used for adjusting operation according to the user; Produce and regulate the operation coding; And be issued to the FM signal transmitter module in the mobile phone protective cover through data line interface; 7 pairs of operation codings of control unit by the FM signal transmitter module are decoded; Then by the tranmitting frequency of control unit 7 regulating and controlling frequency modulation transmitter units 6, thereby realized the adjusting operation of FM signal transmitter module tranmitting frequency.
The music control unit; Be used at the music player that starts mobile phone; The audio signal that music player is play is sent to through data line interface in the FM signal transmitter module of mobile phone protective cover, is emitted on the FM signal receiving equipment by the mode of FM signal transmitter module with frequency-modulated wave.
Switch control unit, whether the audio signal that is used to control mobile phone need send the FM signal transmitter module to through data line interface, realizes the control of FM signal transmitter module emission state.For example: when needs are play handset audio with vehicle-mounted or home audio system; After being adjusted to corresponding frequencies through the FM regulon earlier; Open emission state through switch control unit again, when opening emission state, issue adjusting operation coding to the FM signal transmitter module.
Memory cell is used for using frequency values always when record storage FM regulon is regulated, for user's quick calling.
State detection unit, whether the data line interface that is used to detect FM signal transmitter module and mobile phone is in connection status; When detecting notconnect state, the prompting user will insert.
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 withmobile 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 ofmobile 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 themobile 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:
