Description

A kind of car phone

Technical field

The utility model relates to a kind of Communication Equipment, particularly a kind of car phone.

Background technology

In the modern society of 21 century, automobile has become partner more and more closely in our work, the life.Along with the whole growth in the living standard of people, automobile popularity rate in the family also improves year by year, have a private car at average per 10 families of Guangdong Province urban households, the self-driving travel of middle-long distance also becomes car owners' common program of festivals or holidays, except selecting public transport, automobile is exactly the topmost vehicles to people in go off daily.

At present, generally making a phone call onboard can only be to adopt the individual cell phone and the external world to get in touch, because the function of use of individual cell phone is comparatively single, can not satisfy the needs of current driving.

Summary of the invention

In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of car phone easy to use.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of car phone, it is characterized in that: comprise central processing unit, wireless communication module, sim card socket, phonetic synthesis module, power circuit, central processing unit auxiliary circuit, microphone input and earphone output circuit, the output of power circuit connects phonetic synthesis module, central processing unit and wireless communication module, central processing unit connects phonetic synthesis module, wireless communication module, central processing unit auxiliary circuit, and the wireless communication module connects GSM antenna, sim card socket and microphone input and earphone output circuit.

The beneficial effects of the utility model are: this communication apparatus can be arranged on the vehicle, and is easy to use, and owing to be provided with more functional module, result of use is good.
