Abstract

The utility model introduces modern electronic technology to an inscribed board and provides a multi-function electronic inscribed board. The utility model is characterized in that an electronic circuit, an electronic timer and a loudspeaker, each of which is controlled by the electronic circuit, are arranged in the inscribed board, and furthermore, a luminous tube which is controlled by the electronic circuit is arranged on a decorative picture of the inscribed board. The utility model can utilize sound signals of the fixed point time service and the sending music, etc. of the speaker, and meanwhile, the luminous tube arranged on the decorative picture can send out colorful light signals under the control of the electronic circuit so as to enhance the utilization performance and the ornamental effect of the inscribed board. The utility model has the advantages of multiple functions of alarm, etiquette and doorbell after an infrared sensor is matched.

Description

The multifunction electronic plaque

The utility model relates to hanging decoration and draws technical field, specifically, is a kind of plaque.

Plaque is that people like a kind of gift of giving in the celebrating date such as birthday, opening, but for a long time, the form of plaque is very dull, and function is also very single, and this has influenced the usability of plaque.

Task of the present utility model is, modern electronic technology is introduced, and proposes a kind ofly can send sound and light signal, the colourful multifunction electronic plaque of picture.

Main technical schemes of the present utility model is that the electronic timer, the loudspeaker that electronic circuit are set in plaque and controlled by electronic circuit dispose the luminotron that is subjected to electronic circuit control in its decorative picture.The utility model utilizes the electronic timer timing, utilizes the sound and light signal that loudspeaker and luminotron send to be needed.

The utility model is except that possessing decoration and time clock feature, also can utilize loudspeaker fixed point to give the correct time and send music etc. and cooperate the acoustic signal of setting off effect by contrast with picture, the luminotron that is provided with in the picture sends colourful light signal under the control of electronic circuit simultaneously, therefore, the utility model has been realized goal of the invention, compares with traditional plaque, and its picture is more rich and varied, function increases, and has improved the usability of plaque.

Fig. 1 is the structural arrangement synoptic diagram of the utility model embodiment, Fig. 2 is a schematic block circuit diagram of the present utility model, Fig. 3 is that the function of embodiment triggers and picture is decorated circuit, and Fig. 4 is an embodiment clock acousto-optic start trigger circuit, and Fig. 5 is the thermoelectric infrared sensing circuit of embodiment.

The utility model is described in further detail below in conjunction with drawings and Examples.In embodiment of the present utility model, this electronics plaque also is furnished with external infrared sensor 1, the electric signal of infrared sensor 1 triggers the electric timing switch 2 in the electronic circuit 12, electric timing switch 2 control alarm control circuits 3, the luminotron 5 in warning circuit 3 control loudspeakers 4 and the decorative picture 13.Behind addition infrared sensor 1 and the alarm control circuit 3, the utility model is used in monitoring human body signal in case of necessity, and sends corresponding sound and light alarm signal.On the basis of the foregoing description, also can further expand function: electric timing switch 2 is controlled alarm control circuit 3, ceremony circuit 7 and doorbell circuit 3 respectively through selector switch 6, like this, in different time, different occasion, the utility model also can have warning, ceremony, doorbell function respectively, and loudspeaker 4 and luminotron 5 can send the sound and light signal that adapts.Loudspeaker 4, power supply 9, power switch 10, selector switch 6, electronic circuit board 12 etc. can be fixed on the boundary frame area of plaque, both have been convenient to operation, can not influence the layout of electronic timer 12 and decorative picture 13 again.The electronic circuit 12 of the utility model multifunction electronic plaque can be realized by multiple circuit.Fig. 3, Fig. 4, Fig. 5 have provided the circuit diagram of the described function of a kind of embodiment of realization.Among Fig. 5, the multifunction electronic plaque adopts the passive infrared sensor instant heating to release the fax inductive circuit, when human body passes through the P2288 range of receiving, LM324 amplifies by four high guaily unit, and relatively the timing steady-state circuit among Fig. 3 is triggered in the back, impels 8050 conductings by 3 pin output high level, make the functional integrated circuit sounding of required selection, after amplifying, 386 power amplifiers send the required function sound by loudspeaker, (11) pin ground connection of LM324 wherein, and (4) pin connects positive pole.The course of work of Fig. 3 circuit is as follows: this circuit provides detection signal by Fig. 5, the base stage that is input to BG1 by 1-1 is amplified, and trigger 555 bistable state time base circuits, by 3 pin output noble potential, make 8050 conductings, the time length of conducting has R7 and C4 decision (BG2 and C3, R5, R6 form quick-reset circuit, can save need not).Make after the BG3 conducting IC2, IC3, IC4 speech IC respectively electric work, the selection of function determines by K2, the voice that send carry out audio frequency by the LM386 power amplifier and amplify.Power unit: K1 is～220V alternating current-direct current control power switch, and through bridge rectifier, and+6V voltage stable by drawing behind the three terminal regulator voltage regulation filtering is supplied with the front circuit working by transformer B.Stereoscopic picture plane is decorated circuit, by the multivibrator that the NPN pipe is formed, supplies with picture and decorates, and according to the difference of image content, can adopt multiple acousto-optic circuit.Trigger triode among Fig. 4 is 9013, β 〉=100, and IC is that 555 o'clock bases trigger timing circuit, the size of trigger circuit power can be selected the relay or the controllable silicon of different capacity.
