Description

A kind of children under guardianship are mobile phone dedicated

Technical field

The utility model relates to a kind of cell phone apparatus technical field.

Background technology

Existing cell-phone function is various, and complicated operation costs an arm and a leg, yet for children under guardianship such as the elderly, children, this class special population of students in middle and primary schools and inapplicable! Hanker after mobile phone games as present students at school, functions such as note, pay attention to the class and class study down in the classroom that has had a strong impact on the student; Some charge websites or flame are also by note fixation or reception; Utilize the SMS cheating also very rampant; Also have because of calling unrestricted arbitrarily dial number and bad information service center; Unrealistically compare cell-phone function or the like mutually.Thereby occurred recently that some are mobile phone dedicated on the market again at above-mentioned crowd, but its difference has been to limit the quantity (being generally 2～8) of dial number, and adopt a key dial-up operation.But, cause having a lot of friend or relatives all can't in time get in touch with because of the students in middle and primary schools in the present society often can exceed this quantity with the number that the elderly need contact contact; Simultaneously too high because of its cost, price all belongs to valuables about thousand yuan, uses the mobile phone dedicated potential safety hazard (stolen or robbed) that exists of this class as the children under guardianship of disadvantaged group; Can not effectively reach tutorial monitoring purpose owing to the existence of the problems referred to above, and the demand of children under guardianship's communication range.

The utility model content

The purpose of this utility model be too high for the cost that solves existing mobile phone dedicated existence, fail safe is bad, and children under guardianship group (the elderly, children, students in middle and primary schools) but dialing telephone number quantity is very few, and can not effectively reach tutorial monitoring purpose, with the problem of the demand of children under guardianship's communication range, and then provide that a kind of children under guardianship's is mobile phone dedicated.It comprises LCD display, quadruple linkage keyboard circuit, mobile phone card interface circuit, single chip circuit, radio frequency/receiving circuit, vibrating motor, the tinkle of bells loudspeaker, receiver, transmitter; The data input pin of LCD display connects the video data output of single chip circuit, the data output end of quadruple linkage keyboard circuit connects the Keyboard Control data input pin of single chip circuit, the control data I/O of mobile phone card interface circuit connects the control data I/O of the mobile phone card of single chip circuit, the mobile phone card end of mobile phone card interface circuit connects the output of mobile phone card, the vibration control output of single chip circuit connects the input of vibrating motor, the ring output of single chip circuit connects the input of the tinkle of bells loudspeaker, the speech output end of single chip circuit connects the input of receiver, the phonetic entry end of single chip circuit connects the output of transmitter, the emission of single chip circuit/reception Data Control input/output bus end connects the Data Control input/output bus end of radio frequency/receiving circuit, and the antenna end of radio frequency/receiving circuit is connected with antenna.

Related mobile phone dedicated of the utility model can only be dialed limited telephone number prestoring in the mobile phone card (in the mobile phone card number must use another conventional mobile phone write in advance), and can't dial other phone or bad information service center; With SMS and game function cancellation, reduced harmful effect to greatest extent simultaneously to student's learning life; The quantity of the telephone number that it can be dialed nearly more than 100 (memory size according to the mobile phone card generally can be stored 100～200) farthest satisfy the demand of children under guardianship colony conversation scope; With low cost, estimate that price is more suitable for not having the children under guardianship colony of income and self-protection ability difference for about 200 yuan; Quadruple linkage formula menu operation is easy to be more suitable for the old man, and children use.
