Description

A kind of electronics touches prize case

Technical field

The utility model relates to one and touches prize case, and specifically a kind of electronics touches prize case.

Background technology

Existing prize case of touching is substantially all that a mouth opened by a chest, allows to touch prize people and stretches out one's hand into, do not have other function, seem very dull in some celebrating occasions.

Utility model content

The purpose of this utility model is to provide a kind of electronics to touch prize case, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technical scheme:

A kind of electronics touches prize case, comprise chip U1, resistance R1, electric capacity C1, electrode slice M, triode VT1, keyswitch AN and loudspeaker Y, described electrode slice M contact resistance R1, the resistance R1 other end is connecting triode VT1 collector respectively, triode VT2 base stage and keyswitch M, the keyswitch AN other end connects electric capacity C1 respectively, resistance R5, triode VT4 emitter, diode DW positive pole, electric capacity C2 and triode VT6 emitter, triode VT6 collector connects loudspeaker Y and triode VT5 collector respectively, triode VT6 base stage connecting triode VT5 emitter, triode VT5 base stage connects the O/P pin of chip U1, the described loudspeaker Y other end connects power supply VCC respectively, resistance R3 and triode VT1 emitter, triode VT1 base stage connecting triode VT2 collector, triode VT2 emitter connects the electric capacity C1 other end and resistance R2 respectively, the resistance R2 other end is the contact resistance R5 other end and triode VT3 base stage respectively, triode VT3 collector connecting triode VT4 base stage, the VSS pin of triode VT4 collector difference connecting triode VT3 collector and chip U1, the DSC1 pin of chip U1 connects the DSC2 pin of chip U1 by resistance R2, the VDD pin contact resistance R3 other end respectively of chip U1, the SW pin of chip U1, the electric capacity C2 other end and diode DW negative pole, described chip U1 model is KC5610.

As the utility model further scheme: described diode DW is voltage stabilizing diode.

Compared with prior art, the beneficial effects of the utility model are: as long as the utility model electronics touches prize case, staff touches electrode slice M, and namely can send the electronics sound that may you be hapy and prosperous, increase celebrating atmosphere, circuit structure is simple, and cost is low, is applicable to very much promoting the use of.

Accompanying drawing explanation

Fig. 1 is the circuit diagram that electronics touches prize case.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1, in the utility model embodiment, a kind of electronics touches prize case, comprise chip U1, resistance R1, electric capacity C1, electrode slice M, triode VT1, keyswitch AN and loudspeaker Y, electrode slice M contact resistance R1, the resistance R1 other end is connecting triode VT1 collector respectively, triode VT2 base stage and keyswitch M, the keyswitch AN other end connects electric capacity C1 respectively, resistance R5, triode VT4 emitter, diode DW positive pole, electric capacity C2 and triode VT6 emitter, triode VT6 collector connects loudspeaker Y and triode VT5 collector respectively, triode VT6 base stage connecting triode VT5 emitter, triode VT5 base stage connects the O/P pin of chip U1, the loudspeaker Y other end connects power supply VCC respectively, resistance R3 and triode VT1 emitter, triode VT1 base stage connecting triode VT2 collector, triode VT2 emitter connects the electric capacity C1 other end and resistance R2 respectively, the resistance R2 other end is the contact resistance R5 other end and triode VT3 base stage respectively, triode VT3 collector connecting triode VT4 base stage, the VSS pin of triode VT4 collector difference connecting triode VT3 collector and chip U1, the DSC1 pin of chip U1 connects the DSC2 pin of chip U1 by resistance R2, the VDD pin contact resistance R3 other end respectively of chip U1, the SW pin of chip U1, the electric capacity C2 other end and diode DW negative pole, chip U1 model is KC5610.

Diode DW is voltage stabilizing diode.

Principle of work of the present utility model is: refer to Fig. 1, triode VT1, VT2 etc. form analog switching circuit, when hand does not touch sheet metal M, there is no signal input circuit, triode VT3, VT4 is all in the strong state of cut-off, " may you be hapy and prosperous " chip KC5610 does not have power supply not work, sound is not just had to send, when there being finger arm to contact sheet metal M, the spurious signal voltage of the induction of human body adds to the base stage of VT2, VT1, VT2 conducting, be equivalent to switch close, positive voltage adds to the base stage of VT3 through resistance R2, now VT4 is state of saturation, be equivalent to the VSS pin ground connection of chip KC5610, KC5610 is worked, send the sound of " may you be hapy and prosperous ", continual chimes of doom is removed in the effect of the keyswitch AN open in usual in circuit, as stopping of need reporting to the police, as long as click keyswitch AN, the base potential vanishing of VT2, VT1, VT2 becomes cut-off from conducting immediately, VT3 subsequently, VT4 all ends, loudspeaker Y sound stops.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
