Embodiment

Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.

Embodiment 1

Shown in Fig. 1-2, the full warning device of a kind of tank water comprises two electrodes 5,6 and electronic sound generator 11.Two electrodes are positioned at the opening part of water tank 7.An electrode 5 is connected with second terminals 12 of electronic sound generator through lead, and another electrode 6 is connected with first terminals 13 of electronic sound generator through lead.These two electrode mutual insulatings.

Electronic sound generator 11 comprises switch 1, loudspeaker 2, transistor 3, substrate chip 4, electric capacity 8 and working power 9.

One end of loudspeaker 2 is connected with the SP pin 16 of substrate chip 4, and the other end is connected with the positive pole of working power 9 through switch 1.The Vss pin 17 of substrate chip 4 is connected with the negative pole of working power 9, and TG pin 15 is connected V through electric capacity 8 with working power 9 negative poles _DDPin 14 is connected with the positive pole of working power 9 through switch 1.

The collector of transistor 3 is connected with the SP pin 16 of substrate chip 4, and emitter is connected with the Vss pin 17 of substrate chip 4, and base stage is connected with the OUT pin 18 of substrate chip 4.

One termination TG pin 15 of electric capacity 8, the negative pole of another termination working power 9.

15 on the TG pin of electric capacity 8 and substrate chip 4 is provided with first terminals 13, the V of substrate chip 4 _DD1 on pin 14 and switch are provided with second terminals 12.

Substrate chip 4 is selected from a kind of in KD-153H pattern onomatopoeia IC chip, KD-9300 series music integrated circuit chip or the HFC1500 series music integrated circuit chip.

Transistor is selected among power transistor among the 9013 type silicon NPN, the 3DX201 type silicon NPN among power transistor among power transistor, the 3DG12 type silicon NPN or the 3DK4 type silicon NPN a kind of in the power transistor.

Electric capacity 8 adopts CT1 type ceramic capacitor.
