Description

Wireless type multifunctional mobile telephone Handless

The utility model relates to mobile phone, particularly relates to wireless type multifunctional mobile telephone Handless.

Generally using of mobile phone is the inexorable trend of Development of Communication.Because it can grasp information at any time, therefore,, benefit to the industrial and commercial society that seizes every minute and second at present.

Mobile phone is round-the-clock use generally speaking, and it is the busy middle conversations of both hands that many occasions are arranged, conversation during as driving, except that influencing smooth traffic, still might lead to the traffic accident disaster, therefore, some Northern European countries be about to consider legislation hand held mobile phone conversation when forbidding driving.But conversation is again inevitably between driving, if wiped out, then will make the function of use of mobile phone inferior a lot of; Must not " be put off easily by a slight risk ".Therefore, must on the peripheral equipment of mobile phone, be improved.

The utility model purpose is to provide a kind of wireless type multifunctional mobile telephone Handless to address the above problem.

Embodiment of the present utility model is as follows:

The wireless type multifunctional mobile telephone Handless that the utility model provides comprises:

One is linked to charging circuit and supplies the power socket hole of charger intercalation;

One is linked to the FM power amplification circuit, supplies the antenna pedestal hole of the intercalation binding of antenna;

One is linked to FM modulation intelligence, supplies the transmitting-receiving seat hole of the intercalation of microphone and earphone.

It is characterized in that, this wireless type multifunctional mobile telephone Handless, the box-like body for the top opening has:

One room that supplies ccontaining mobile phone to use;

One for the dividing plate that is positioned at room supported underneath mobile phone, the enclosure space content circuits plate under the dividing plate;

A connector protrudes on the dividing plate, and its terminal is corresponding to the terminal of mobile phone bottom, and has the circuit that circuit is linked to circuit board respectively.

Be located on the circuit board in the space of dividing plate below and have a charging circuit, one MIC amplifying circuit, circuit and SP output amplifier are linked to a FM modulation smart circuit respectively, FM modulation intelligence then is linked to the FM modulation circuit with the SP output amplifier, be all known technology, at this not in giving unnecessary details;

Can add the anchor clamps of clamping in the room back;

Can add behind in room and put one for linking fixing support plate with the cars frame.

Via enforcement of the present utility model, can exempt hand-held puzzlement, and often keep charged state, can obtain preferable communication effect, also make the function of mobile phone, reach perfection.

Further describe the utility model below in conjunction with accompanying drawing:

The figure elements symbol description:

Room 1 dividing plate 2 connectors 3

5 antenna pedestal holes 6, circuit board 4 power socket holes

Transmitting-receiving seat hole 7 anchor clamps, 8 support plates 9

Charging circuit 41 MIC amplifying circuits 42 SP output amplifiers 43

External H/F smart circuit 44 power supply processing circuits 45 FM modulation intelligence 46

FM modulation circuit 47 FM power amplification circuits 48

As shown in the figure, basically, Handless of the present utility model is the box body of top opening, there is a room 1 box body inside, and its below is a dividing plate 2, and has a connector 3 to be linked to the circuit board 4 of its below, the bottom has 5, one antenna pedestal holes 6, a power socket hole and a transmitting-receiving seat hole 7 to form in addition.

Wherein, the size of room 1, corresponding to the width and the thickness of mobile phone, when making mobile phone within it, unlikely loosening or rock.

Dividing plate 2 is divided into the room 1 of top and the support when ccontaining as mobile phone, and makes the circuit board 4 of its below be air-tight state, to prevent infiltration and to pollute.

Connector 3 is corresponding to the terminal of mobile phone bottom, and has circuit to be linked to circuit board 4 respectively.

Circuit board 4 is a plate body, be placed in dividing plate 2 belows, it as shown in Figure 1, comprise a charging circuit 41, one MIC amplifying circuits 42, one SP output amplifiers 43, an one external H/F smart circuit 44 and a power supply processing circuit 45, and MIC amplifying circuit 42 is linked to a FM modulation intelligence 46 respectively with SP output amplifier 43, and 43 of SP output amplifiers are linked to a FM modulation circuit 47 and further are linked to a FM power amplification circuit 48, in order to link the transmitting-receiving of antenna as signal.

Power socket is located at the bottom, and is linked to charging circuit 41, is charging by the hole that is plugged in cigar lighter in the car.

The grafting of bottom for antenna is located in antenna pedestal hole 6, and the one end is linked to FM power amplification circuit 48, so that the frequency modulation signal that receives amplification, as follow-up processing.

The bottom also is located in transmitting-receiving seat hole 7, and for plant earphone A and microphone B, the one end is linked to FM modulation intelligence 46.

In addition, can clamping for making it, as shown in Figure 4, add in the back and to put anchor clamps 8, and, also a support plate 9 can be set in behind for it can be linked on the automobile-used pillar (knowing).
