The charging function of the mobile phone, the earphone of the mobile phone, the active amplifying circuit and the loudspeaker are combined into an integral body, consequently the new function is realized; The utility model can charge for the mobile phone as well as can communicate under the situation of not influencing driving, consequently the driving safety is ensured. The design of the artistic modelling of the multipurpose cell phone hand-free device not only can provide a fixed placing position for the mobile phone to make the mobile phone uneasily missed, but the graceful profile can also beautify the environment.

Description

The multipurpose mobile phone hands-free device

One, technical field:

The utility model relates to a kind of multipurpose mobile phone hands-free device.

Two, technical background:

When general mobile phone uses in car, need the driver to make a phone call with a hand in the process of moving, the another hand is driven steering wheel, thereby brings unsafe hidden danger for the car of driving process; In the prior art, though original car phone has hands-free device, it can only use in car; And the earphone of prior mobile phone, though can move function such as charging not; In addition, because the mobility of mobile phone, the placement location that its neither one is relatively more fixing is so brought problem such as lose easily.

Three, summary of the invention:

The purpose of this utility model be to provide have raise one's voice, the multi-purpose vehicle mounted hands-free telephone device of charge function.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of multipurpose mobile phone hands-free device, its special character is: the circuit 9 that this device joins by loud speaker 8, with automobile power source, amplifying circuit 7, cell phone charging circuit 10 constitutes, and described cell phone charging circuit 10 is connected with automobile power source; The earpiece holes 2 of described mobile phone is connected with amplifying circuit 7, and the voice signal of mobile phone is passed to loud speaker 8 by amplifying circuit 7.

Between the earpiece holes 2 of above-mentioned mobile phone and the amplifying circuit 7 switching circuit 5 is set.

On the above-mentioned cell phone charging circuit charging indicator light is set.

The external form of this above-mentioned device is animals shaped design.

On the base of this above-mentioned device fixture is set.

The utility model is with respect to prior art, and its advantage is as follows:

1, the utility model can not only be given cell-phone charging, and can converse under the situation that does not influence driving, thereby has guaranteed traffic safety.

2, the utility model also is provided with switching circuit, and when the conversation need to be keep secret, the energy off switch disconnects itself and loud speaker, uses the earphone conversation.

Four, description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the utility model circuit theory diagrams;

Five, embodiment:

Accompanying drawing number is:

1-mobile phone 2-earpiece holes 3-headset plug 4-earphone lead

The active amplifying circuit of 5-switching circuit 6-pick-up 7-

8-loud speaker 9-power lead 10-cell phone charging circuit

11-charging lead 12-cell-phone charging plug

Referring to Fig. 1, the utility model the earphone of the charge function of mobile phone and mobile phone and active amplifying circuit 7 and loud speaker 8 are combined as a whole, thereby have realized new function; The circuit that the utility model joins by loud speaker 8, with automobile power source, amplifying circuit 7, cell phone charging circuit 10 constitutes, and described cell phone charging circuit 10 is connected with automobile power source lead 9; The earpiece holes 2 of described mobile phone is connected with amplifying circuit 7 by earphone lead 4, and the voice signal of mobile phone is passed to loud speaker 8 by amplifying circuit 7.During use, mobile phone is placed in this device, when mobile phone does not have electricity, can gives cell-phone charging by this device; When needs were conversed, the conversation signal of mobile phone was released sound through active amplifying circuit 7 and loud speaker 8 by line, during conversation, by pick-up 6 voice signal was spread out of by mobile phone again.

When conversation during need to be keep secret, between the earpiece holes of mobile phone and amplifying circuit, switching circuit 5 is set, off switch can utilize the original earphone of mobile phone to converse.

Certainly, this device not only can be placed in the car, also can be placed on places such as office, parlor.It can not only charge, converse, and can also allow mobile phone that fixing placement location is arranged, in order to avoid lose.

Referring to Fig. 2, the utility model specific embodiment is the circuit theory diagrams of NOKIA3310 type, and it has comprised charging circuit, and the physical circuit figure for the discharge road is provided with charging indicator light in its charging circuit, and headset plug wherein is a NOKIA8210 type headset plug.

In order to make stable being placed in the car of this device, on the outer casing base of this device, fixture is set, its Pasting pad etc., in addition for making this device can give the position of a fixing placement of mobile phone, it can design plug-type structure, allow mobile phone be inserted and secured in it, and its profile can be designed to animals shaped design.
