Abstract
The utility model discloses a device for guarding and against theft which can be used for no power areas; the alarm method is peculiar, and the device for guarding and against theft can automatically play the beautiful music when working. The device for guarding and against theft is mainly composed of a control mechanism circuit and a sound mechanism circuit. The use method is that a plurality of fine metal wires are distributed in a warning area; both ends of the fine metal wires are connected in parallel between the input terminal of the control circuit and the ' ground' after the fine metal wires are mutually connected in series. In normal times, the control circuit and the sound circuit do not work. When someone enters into the warning area to break the fine metal wires, the loudspeaker automatically play the music to be served as the alarm signal. The volume of the device for guarding and against theft is as big as the volume of the cigarette box; the carrying and the use are very convenient.
Description
The utility model belongs to the electronic product as warning usefulness.
Common alarm generally all needs AC power, or the AC power of not needing is arranged, but when reporting to the police sound generally all compare dull, ear-piercing, make one nervous.The utility model is to have done improvement at above-mentioned shortcoming, makes it to be applicable to the area that lacks AC power, and melodiousness again during warning is the warning device of a kind of " can sing ".
The utility model mainly is made up of control gear and sound equipment mechanism two part circuit.Control gear is an integrated circuit that is made of multistage reverser, and sound equipment mechanism then is the music integrated circuit of an external loudspeaker, because power consumption is atomic, adopts a laminated battery and a joint No.5 cell to get final product operate as normal.All element all is assembled in one only has cigarette to close in the so big plastics zygote.
Principle of work of the present utility model is very simple: at ordinary times, the input end of control gear (multistage reverser integrated circuit) and " " between by the short circuit of external tinsel institute, be output as noble potential, relay is not worked, music integrated circuit can not be triggered, loudspeaker is sounding not, in case tinsel disconnects, the control gear circuit overturns immediately, its output terminal becomes electronegative potential by original noble potential, the relay adhesive, music integrated circuit is triggered, and loudspeaker just can be play one section dulect melody.
Using method: frontier front or reform-through-labour farm can lay some inconspicuous fine wires around warning region, as senser element, mutually after the series connection, its two ends are connected in close on two outer binding posts, get final product energized, this moment, loudspeaker was not answered sounding, if sounding should check whether tinsel opens circuit.Home security then can be installed in tinsel in doorframe, window or drawer etc. and locate.Tinsel is to adopt No. 24 or No. 26 electrician's fuses are advisable.Because this fuse diameter is little, be not easy to be found.
If seal in a moving disconnected button between two binding posts outside closing, the utility model not only can but also can be used as electronic door bell and uses.
