Abstract
The utility model relates to an alarm for children crossing the street, belonging to an electronic alarm device. The utility model is characterized in that a loudspeaker, an alarm signal generating electric circuit, and a power source are arranged in a shell. Audible alarm signals which are sent out by the alarm for children crossing the street have the advantage of fearlessness for the obstruction of crowds or other objects so that the utility model is an ideal alarm device for children crossing the street.
Description
Children cross the street alarm, belong to a kind of electronic alarm device.
Existing children cross street warning articles for use be the cap of the color that comes into the picture easily or school bag etc. arranged.
The purpose of this utility model is to replace the color alerting signal with audible ringing signal, the shortcoming that can not be it is found that when overcoming color signal by retaining, thereby the safety when guaranteeing that children cross the street.
The utility model is loudspeaker, alerting signal to be housed produce circuit and power supply and constitute in a casing.The break-make that switch is used to control power supply wherein is housed on the casing, promptly whether controls alarm work.Alerting signal produces circuit by being that core is formed with the integrated circuit that has the alarm sound signal, and the alarm sound signal adds the language alarm signal by language alarm signal or simple sound alerting signal or simple sound alerting signal and forms.
The utility model children cross alerting signal that the street alarm sends and cross street warning articles for use with existing children and compare, and it has is not afraid of the advantage that crowd or other object block.
Accompanying drawing 1 is crossed the basic electrical schematic diagram of street alarm for children.Wherein Y is that loudspeaker, BXCD are that alerting signal produces circuit, E is that power supply, K are control power supply and alarm work whether switch.
Accompanying drawing 2 is crossed the profile synoptic diagram of street alarm for the embodiment children.
Accompanying drawing 3 is crossed the electrical schematic diagram of street alarm for the embodiment children.
Contrast description of drawings embodiment below.
The profile that children cross the street alarm as shown in Figure 2, wherein (1) is casing, (2) are power switches, i.e. alarm work whether gauge tap, (3) are to be linked with, and are used for alarm is suspended on children's front or other position.According to basic electrical schematic diagram shown in Figure 1, the embodiment electrical schematic diagram as shown in Figure 3.Wherein K is a power switch, be (2) among Fig. 2, power supply E is made up of two joint 1.5V batteries, IC is the integrated circuit that has the simple sound alerting signal, R is the resistance of decision alarm sound tone, BG is the power discharging transistor of integrated circuit (IC) output signal, and Y is the loudspeaker that the alerting signal of final electric form is converted to the alerting signal of form of sound.
In addition, if the integrated circuit (IC) among Fig. 3 is used the integrated circuit that has the language alarm signal instead or had the integrated circuit that the simple sound alerting signal adds the language alarm signal, what send during alarm work so is exactly that language alarm signal or simple sound alerting signal add the language alarm signal.
Claims (4)
1, a kind of children cross the street alarm, it is characterized in that being equipped with in a casing loudspeaker Y, alerting signal generation circuit BXCD and power supply E.
2, cross the street alarm according to the described children of claim 1, it is characterized in that being equipped with the K switch of control power supply.
3, cross the street alarm according to the described children of claim 1, it is characterized in that alerting signal produces circuit BXCD and produces circuit or simple sound alerting signal by language alarm signal generating circuit or simple sound alerting signal and add the language alarm signal generating circuit and form.
