Abstract
The utility model provides a hand-free device of a mobile telephone for car drivers, which comprises a mobile telephone and a cassette player of a car and is additionally provided with a transmitter with a retaining clip, a wire connector and a magnetic tape type connector which is composed of a shielded box, a magnetic head and an audio frequency transmission circuit. The transmitter is connected with a receiving signal pin of a mobile telephone data port through the wire connector, and the magnetic tape type connector is connected between the cassette player of an automobile and the receiving signal pin of the mobile telephone data port. The drivers can realize the communication with the outside without holding the mobile telephone by utilizing the utility model. The utility model has the advantages of enhanced driving security, no need of additional electric source, simple structure, convenient operation and low cost.
Description
The utility model provides a kind of driver to use hands-free device, belongs to the telephonic communication technical field.
At present, on a large amount of automobile communication device is not installed.The driver is in the way of driving, and when mobile calls, the driver often vacates a hand, the hand held mobile phone conversation.Do both inconvenient, dangerous again like this.
The purpose of this utility model provides a kind of driver and need not the driver that cell-phone just can carry out communication use Handless unit for mobile telephone in the way of driving.
The purpose of this utility model is achieved in that
The cassette player that comprises mobile phone and automobile, that has set up the band geometrical clamp send microphone, electric wire connecting junction and magnetic tape type connector, wherein send microphone to connect the accepted call signal pin of mobile phone data port through electric wire connecting junction, the magnetic tape type connector comprises a shielding box, the magnetic head place that the corresponding cassette player of shielding box is read tape establishes a magnetic head, audio transmission circuit is housed in the shielding box, and the output termination magnetic head of audio transmission circuit, its input connect the telecommunication signal pin of mobile phone data port through electric wire connecting junction.
Described driver uses Handless unit for mobile telephone, electric wire connecting junction comprises plug, patchplug and multi-tap, the input of patchplug and audio transmission circuit and send microphone to be connected with lead wherein, corresponding multi-tap connects the mobile phone data port through plug.
Described driver uses Handless unit for mobile telephone, audio transmission circuit comprises two resistance and an electric capacity, wherein an end of first resistance connects the telecommunication signal pin of mobile phone data port through electric wire connecting junction, the magnetic head on its another termination shielding box, successively through second resistance and capacity earth.
Its operation principle is: the magnetic tape type connector inserts in the tape groove of cassette player, the magnetic head of magnetic tape type connector just contacts connection with the magnetic head of cassette player, make the telecommunication signal pin of driver's conversation signal by the mobile phone data port, again successively through plug, lead, multi-tap, patchplug, lead, audio transmission circuit, magnetic head, cassette player plays back, driver's dialogue signal is via sending microphone, lead, patchplug, multi-tap, lead, plug, the accepted call signal pin of mobile phone data port transfers out, and need not hand held mobile phone like this and just can realize external conversation.Send microphone can be fixed on the position of the convenient speech of driver by geometrical clamp.
The utility model compared with prior art has following advantage:
1, need not additional power source, utilize automobile audio to play the conversation signal of making driver's mobile phone, the driver need not hand held mobile phone just can realize external conversation through sending microphone, has improved drive safety greatly, and simple in structure, easy to use, cost is low.
2, the mobile phone of different model, the sample diversified in specifications of its data port, the plug corresponding with it is also different.Set up multi-tap, patchplug,, only needed to change the plug corresponding, switched through plug by multi-tap again and can be communicated with whole communicator, the driver need not to change mobile phone with it at the mobile phone of different model, practical.
Fig. 1 is a fundamental diagram of the present utility model;
Fig. 2 is the circuit theory diagrams of the utility model embodiment;
Among Fig. 1, magnetic tape type connector 8 comprises a shielding box 12, in the shielding box 12 audio transmission circuit is housed, and the magnetic head place that shielding box 12 corresponding cassette players 10 are read tape establishes a magnetic head 9.Plug 5 and the 7 corresponding grafting of mobile phone data port, multi-tap 4 and patchplug 3 corresponding grafting, what have geometrical clamp 2 send microphone 1 successively through lead, patchplug 3, multi-tap 4, lead, plug 5 connects the accepted call signal pin of mobile phone data port 7, the telecommunication signal pin of mobile phone data port 7 is successively through plug 5, lead, multi-tap 4, patchplug 3, lead connects the audio transmission circuit of magnetic tape type connector 8, the output termination magnetic head 9 of audio transmission circuit, magnetic tape type connector 8 inserts in the tape groove 11 of cassette player 10, and the magnetic head 9 and the cassette player 10 of magnetic tape type connector 8 read the magnetic head of tape and connected.
Among Fig. 2, send the telecommunication signal pin 1 of microphone 1 through resistance R 0 plug 3, the accepted call signal pin 5 of plug 3 connects magnetic head 9 and resistance R 2 respectively through resistance R 1, and the other end of resistance R 2 is through capacitor C ground connection.
