Compared with prior art, the time delay circuit of the utility model employing is made up of resistance R 1, resistance R 2, capacitor C 1, aerotron; Voice control circuit includes in advance the voice sheet DIP/SOIC with the voice control program; Can join to be inserted with and be installed under the cushion and can produce often opening button S1 and can join and being inserted with the normally closed button S2 that is installed on the safety strap setting fastening seat of outside input signal by the mode of pushing, by being connected of above-mentioned parts and each corresponding pin of voice sheet DIP/SOIC, can accomplish to point out the fastening safety belt effect.And guarantee people sit down the back in the time of setting not toot be loudspeaker.Low, the easy installation of its cost, the convenient use are the desirable sound prompt devices of the vehicle and large-scale item of recreation safety instruction.

Description of drawings

Fig. 1 is the utility model circuit principle structure scheme drawing.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Fig. 1 illustrates, and the sound prompt device of fastening safety belt comprises direct supply G, loudspeaker J, time delay circuit, voice control circuit; Time delay circuit is made up of resistance R 1, resistance R 2, capacitor C 1, aerotron, and voice control circuit includes in advance the voice sheet DIP/SOIC with the voice control program; Voice sheet DIP/SOIC pin 28 ends, 16 end pig-tail wires are divided into four the tunnel: the first via is connected to voice sheet DIP/SOIC pin 4 ends; The second the tunnel is connected to voice sheet DIP/SOIC pin 12 ends, 13 ends and ground respectively through cond C2; The resistance R 1 of Third Road in time delay circuit divided two-way again, and one the tunnel through capacitor C 1 ground connection; Another road is through the grounded emitter of resistance R 2, aerotron, and transistor collector end and voice sheet DIP/SOIC pin 23 ends can be joined and are inserted with the normally closed button S2 that is installed on the safety strap setting fastening seat; For improving the amplification of circuit signal, aerotron is the emitter follower that two aerotrons connect formation; For assurance device is worked more reliably, cond C2 is 0.1 μ F; The 4th pass leading-out terminal and dc power anode end can be joined to be inserted with and be installed under the cushion and can often open button S1, direct supply G negative pole end ground connection by what the mode of pushing produced outside input signal; Be connected to loudspeaker J between voice sheet DIP/SOIC pin 14 ends, 15 ends, the impedance of loudspeaker is that 16 Ω are advisable.

Voice sheet DIP/SOIC has respectively:

For guarantee people sit down the back in the time of setting not toot to be loudspeaker, time delay circuit delay time T be 20 seconds to 50 seconds, resistance R 1 value 60K Ω～325K Ω; Capacitor C 1 value 220 μ F～470 μ F.

Can be according to different needs, delay time T of the present utility model is set to 20 seconds to 50 seconds, after people take cushion, oppress to be installed in by the mode of pushing and often open button S1 under the cushion, produce outside input signal, often open the conducting of button S1 close circuit, voice sheet DIP/SOIC energising, time delay circuit work, in element value in the time delay circuit determine that delay time T is provided with 20 seconds to 50 seconds, aerotron V1, not conducting of V2, therefore not toot be loudspeaker, give the time of a fastening safety belt of seat person, surpass the set time, if still do not fasten seat belts aerotron V1, the V2 conducting, trigger current arrives playback PLAYL pin by the normally closed button S2 that is installed on the safety strap setting fastening seat, makes loudspeaker J sounding; The utility model in the cushion sends the voice suggestion of fastening safety belt and produces sound, for example, has in advance with the voice sheet DIP/SOIC of voice control program to be preset with " rule that observe traffic laws are noted (machine) safety of riding, and Buckle Up ".Like this for the good safety strap person of timely setting fastening, the utility model is sounding not, not annoying, and keep quiet in the car (machine), to forgetting setting fastening or setting fastening jail safety strap person not really, in time send out and produce the prompting fastening safety belt, if insist on the not good safety strap of setting fastening, the utility model then continuously repeats to send to your prompting the propaganda of " rule observe traffic laws; note 2 (machine) safety by bus, Buckle Up "; And behind the good safety strap of setting fastening, the normally closed button S2 that is installed on the safety strap setting fastening seat disconnects, and trigger current ends, and voice sheet DIP/SOIC dead electricity quits work, and loudspeaker J is sounding not.
