Description

A kind of hand-written short message transmitter that is used for mobile phone

Technical field

The utility model relates to a kind of hand-written short message transmitter that is used for mobile phone, belongs to the communication apparatus technical field.

Background technology

Along with the development of mobile phone technique, smart mobile phone begins to come into people's life, people can be on mobile phone with an input information, can bulk SMS, send out email etc., can customization function, these all are that conventional mobile phone does not possess.But the smart mobile phone price is almost all more than 3000 yuan, have in addition up to 6,7,000 yuan, exceed at least more than 2000 yuan compared with the regular handset of about 1,000 yuan of average prices, this just makes smart mobile phone unpopular, is difficult to popularize.It is the first that the mobile phone owning amount of China occupies the whole world, and the quantity that mobile phone sends SMS message also occupies first in the whole world, and as the cellphone subscriber of quantity maximum, be that income is in low and middle-grade cellphone subscribers, the mobile phone that uses is because button is few, input Chinese is very inconvenient, and existing mobile phone is having very big defective aspect address lookup, short-message cluster-sending, the short message storage.

" duanxinwang " of present domestic e-commerce has the part above-mentioned functions, but owing to be miscellaneous function as palmtop PC, so SMS is not strengthened, and there are volume big, cost an arm and a leg (more than 1000 yuan), the single shortcomings such as (being merely able to connect the mobile phone of infrared interface) of connected mode, can't large-scale promotion.

Summary of the invention

The purpose of this utility model is to propose a kind of hand-written short message transmitter that is used for mobile phone, and major functions such as function that smart mobile phone is the most frequently used such as handwriting input, short message transmission, mass-sending, address book intelligent retrieval integrate, to reduce equipment cost greatly.

The hand-written short message transmitter that is used for mobile phone that the utility model proposes comprises:

The touch-screen that is used for the handwriting input short message, touch-screen is connected with A/D converter;

What be used for touch-screen is produced carries out the A/D converter that A/D changes with the corresponding simulation dot matrix signal of short message literal, and A/D converter is connected with central processing unit;

Be used for the simulation dot matrix signal is handled and handwritten form identification, and recognition result be converted to the central processing unit of short message format;

Be used to store the dynamic memory of intermediate results of operations signal, dynamic memory is connected with central processing unit;

Be used to store the handling procedure of central processing unit and the static memory of recognition result is connected with central processing unit;

Be used to show the liquid crystal display screen of recognition result, liquid crystal display screen is connected with central processing unit;

Be used for short message is sent to the button of other mobile phones, button is connected with central processing unit;

Be used for the serial ports that links to each other with other mobile phone, serial ports is connected with central processing unit;

Be used for the infrared interface that links to each other with other phone, infrared interface is connected with central processing unit.

The hand-written short message transmitter that is used for mobile phone that the utility model proposes, make regular handset increase following function: handwriting input, short-message cluster-sending, short message editing and forwarding, high-capacity short messages can be stored, or, have more powerful good friend's grouping, inquiry, mass-sending function from the short message that the PC download edits, also can add functions such as electronic dictionary, MP3, recording pen, digital camera.

The advantage of this hand-written short message transmitter is: this machine does not have wireless communication module, can reduce the cost of terminal so greatly; Connect with mobile phone by serial ports or infrared mouth, use the wireless communication function of mobile phone to carry out the transmitting-receiving of short message; Use touch-screen to carry out handwriting input, more more convenient, quicker than traditional keyboard input.
