Abstract

The utility model relates to a computer telephone with PDA function, which belongs to an electronic product of the class of communication and is composed of PDA and a communicative base. When two parts are connected together, the functions of telephoning, receiving/emitting a fax without paper, and browsing E-mails and INTERNET, and the assistant functions of prompting, memorandums, dictionaries, etc., can be completed, wherein, an information exchange part namely the PDA can be carried alone for completing the functions of a personal palmtop computer, which means that the PDA can be taken out from the communicative base. Information in the PDA can be flown along with a user. The communicative base without the PDA can be used for recording data and can also be used for telephoning, receiving the fax independently and recording left words of a telephone.

Description

Computer telephone with PDA function

The utility model belongs to the communication class electronic product.It is a kind of modern smart phone.This phone organically combines multiple communication products, for the user provides maximum convenience.

Similar products at home and abroad has situation now: telephone set does not have important breakthrough on function for many years, mainly still is used for conversation.Some high-grade phones have increased some functions easily, as hands-free, speed dialling, caller identification etc.And for example the phone automatic answering machine can be recorded to phone when owner goes out, and the record form is always based on tape.At present, the higher digital recording answer phone of swift to operate, tonequality occurs.Fax also is a kind of more traditional information transfer means.The host-host protocol of fax is open, mainly contains two kinds of 9600BPS and 1440BPS, and its recording mode is to use paper.Send with facsimile machine after will printing when writing regular fax, recipient's fax is preserved, filing is consulted not very convenient again.And computer MODEM receives/sends a fax because of complicated operation, and also inconvenience is popularized.Aspect the equipment of Email, online, at present still only by computer.Enter the information age, INTERNET has become an indispensable part in many people's work, but because of the computation complexity, the domestic consumer is still few.Set-top box device is low because of TV resolution, and flicker is serious, is not suitable for browsing Word message, therefore fails popular.Based on the desk-top equipment for surfing the net of Webphone, requirement can be browsed generic web page, has the colour liquid crystal display device of the above resolution of 640*480 mostly, and configuration requirement is not second to PC, and the LCD cost is very high, therefore costs an arm and a leg function inferior PC far away.This equipment can't be carried, and has also limited its scope of application.Traditional PD A is convenient to carry, and main function is a telephone directory, is the aid of people's communication, but it does not possess communication function, can't pass through the telephone directory dial-in direct, or write down and show incoming person's information also not possess functions such as online, fax as mobile phone.And information interaction is very inconvenient, is difficult to and other PDA or PC communication.
