Abstract

The utility model relates to a bag with a speech warning function. A circuit board is arranged in the existing bag. A circuit of the circuit board is composed of a power supply, a timer, a speech storage circuit, an amplifier, a loudspeaker, and a switch, wherein, the output end of the timer is connected with the triggered input end of the speech storage circuit. The output end of the speech storage circuit is connected with the input end of the amplifier. The output end of the amplifier is connected with the loudspeaker. The switch is arranged in the connection position of a bag shoulder strap and a bag body to control the power supply to switch on or switch off. The utility model has the advantage of simple structure. The utility model has a circulating speech warning function. The utility model can be used as bags for middle school students and pupils. The utility model can remind students of paying attention to traffic safety, going to schools on time, and going home on time. The safety of the students on the way home and on the way to schools can be improved.

Description

The school bag of tool voice prompting function

The utility model relates to a kind of school bag, a kind of more precisely school bag with voice prompting function.

The school bag function singleness used of student in the market, and along with the development of society, the quickening of people's rhythm of life, most students need go to school separately, because the student is those student children that just imparted rudimentary knowledge to beginners particularly, usually own child's childlike innocence is at one's discretion on the way chased, is quarrelled and fought noisily, and selfless pushes way by shoving or bumping, exhorting of father, mother forgotten, do not note the vehicle of the benz of coming and going in great number on the highway, often cause unexpected injures and deaths, bring great loss for family and society.In these years, student's vehicle casualty accident significantly rises, thereby the safety on the road that how to guarantee that the student goes to school, classes are over, reduces the accident of student's vehicle injures and deaths, becomes the social concern that presses for solution day by day.

The purpose of this utility model is the deficiency that overcomes prior art, provides a kind of simple in structure, can in loco parentis point out the children's attention traffic safety constantly, goes to school on time, goes home on time, has the school bag of voice prompting function.

The utility model is to adopt following proposal to realize: in existing school bag a circuit board is set, its circuit is made up of power supply, timer, voice memory circuit, amplifier, loudspeaker, switch, described timer output end is pressed the voice memory circuit and is triggered input, the output termination amplifier input terminal of voice memory circuit, the output termination loudspeaker of amplifier, switch are arranged at school bag braces and school bag body junction control on/off.

Below in conjunction with the accompanying drawing case concrete structure of the present utility model is described.

Accompanying drawing 1 is the utility model structure diagram.

Accompanying drawing 2 is an electric theory diagram of the present utility model.

Accompanying drawing 3 is circuit theory diagrams of the present utility model.

With reference to accompanying drawing 1,2, the utility model is that a circuit board 4 is set on existing school bag 1, its K switch is arranged at school bag braces 2 and school bag 1 junction, the control on/off, K switch is a spring contact switch, described circuit board is by timer (A), voice memory circuit (B), amplifier (C), loudspeaker (D), power supply (E), switch (K) is formed, described timer (A) output termination voice memory circuits (B) trigger input, the output termination amplifier input terminal of voice memory circuit (B), the output termination loudspeaker (D) of amplifier (C), the break-make of switch (K) control power supply (E), concrete operation principle is as follows: switch closure is connected power supply, timer regularly triggers sound circuit, and sound circuit circulation output voice signal promotes the loudspeaker sounding after amplifier amplifies.

Accompanying drawing 3 is a most preferred embodiment of the present utility model, its particular circuit configurations is as follows: the REP end of speech chip MSSI061, Vcc termination power positive pole, the OSC end connects positive source through resistance R 1, the base stage of Vout termination triode V, the emitter stage of Vss end and triode V and 2 ends of K switch are ground connection together, 1 termination power negative pole of K switch, the colelctor electrode of triode connects loudspeaker, another termination positive source of loudspeaker.

The utility model operation principle is as follows: the back school bag, and the braces tension, spring 5 is compressed, contact 3 contacts make the closed power supply of connecting of K switch, and power supply E gives sound circuit and amplifier power supply, voice signal is exported in the Vout end circulation regularly of speech chip MSSI061, delivers to the base stage of triode V, and the emitter stage output by triode V after triode amplifies promotes loudspeaker M sounding, put down school bag, braces loosens, spring reset, and the contact disconnects, K switch is disconnected block power supply, entire circuit quits work.

MSSI061 in the utility model is disposable chipspeech, circuit is made up of timer, control section, voice memory circuit in it, after will warning the voice typing, can use for a long time, the OSC end of MSSI061 is timer oscillating circuit outer meeting resistance end, the REP of MSSI061 end is the circulation output control terminal, with high level on this termination, and its output end vo ut output voice signal that regularly circulates.

In sum, the utility model is simple in structure, easy to use, has the circulation voice prompting function, as students in middle and primary schools' school bag, can remind the student to note traffic safety, go to school on time, go home on time, the security on the road of improving that the student goes to school, classes are over.
