Preventive effect.
The specific implementation of the light-operated photoacoustic dual-controlled alarm that the present embodiment is provided includes：Try one's best by Fig. 2 during welding
Middle position of components finally should be welded by from left to right top-down order, integrated circuit, can so be reduced and be connected with mistake by mistake even,
While being also convenient for debugging and checking.Particular device photo resistance Rcds is used in this circuit, with first being tested with universal meter before
Resistance when its resistance when by light and backlight.Because photo resistance is to light quite sensitive, using when to avoid daylight
Lamp direct irradiation.Tin will be gone up first using solder horn during electric iron, for the oxidized pad in surface and the pin of components and parts,
Must be clean with fine sandpaper polishing, scaling powder is coated, weld interval is unsuitable long, otherwise easily scorches element, can use if necessary
Tweezers are clamped pin and help radiate, and integrated circuit finally should be welded.Electric iron is welded using waste heat after wanting reliable ground, or power-off
Connect.When flatiron is left after scolding tin complete wetting solder joint, the direction for removing flatiron should be general 45 degree of direction.The electricity being welded
Road plate loads volume together with loudspeaker BL, power switch S and battery GB etc. and suitably insulate little inside the shell, for example, can select plastics
Or the capsule that the material such as lucite is made, photographic hole is outputed for photo resistance on panel, be that sound releasing hole outputed by loudspeaker,
An aperture is respectively opened at two light emitting diodes.By LED lighting and loudspeaker sounding, sound-light double warning is realized.
After alarm is assembled, the resistance of ascending slow regulation potentiometer BP during debugging, it is in loudspeaker BL and faces
Boundary's sounding state.Optimal light sudden change triggering warning sensitivity, the appropriate resistance for changing second resistance device R2 can be obtained
(240-470K) come adjust audio alert sound imitate till satisfaction.Balcony or door and window mouth etc. are placed in using fashionable dress alarm
Thief must notice that the aperture for opening photo resistance alignment can well receive extraneous available light, well can visit again through part
Survey the direction that uninvited guest passes through.Whole warning circuit power consumption very little, static total current are less than 100 μ A, electric current one during work
As ＜ 150mA, therefore electricity consumption is saved very much, and often changing once new dry cell typically can be continuously using half a year to 1 year.
The alarm induction sensitivity that the present embodiment is provided is high, can achieve the same alarm of acousto-optic, makes in noisy environment
Sound-light double warning alert is realized, if alarm is placed in balcony courtyard door etc., moreover it is possible to play prevention children and climb, reach
The head of a family is assisted to nurse the purpose of child.Four tones of standard Chinese pronunciation audio ic CW9561 can be sent out ambulance in addition to police whistle sound is sent
Sound, fire engine sound and machine gun sound, can be selected according to personal like, while the speech IC for changing different model can turn
It is changed to the alarm of different purposes；The utility model circuit structure is simple, with low cost, with well warning property and security,
Easily make, and have certain functions expanding, sensitivity is high, easy to use, it is easy to mass produce, general so as to be conducive to
And.
This specific embodiment is that the technical solution of the utility model is clearly and completely described, enforcement therein
Example is only a part of embodiment of the present utility model, and is not whole embodiments.Based on the enforcement in the utility model
Example, those skilled in the art belong to this in all other embodiment not obtained on the premise of the creative work
The protection domain of utility model.
