Abstract
The utility model relates to a sound control power socket, which is provided with a sound control circuit board connected between a power plug and a power socket. The utility model is characterized in that a sudden sound signal triggers a bistable circuit after two-stage magnification, and then triggers a thyristor so as to realize the contactless control of the alternative states between power on and power off of the socket. The utility model has the advantages of compact structure and economic usefulness. The power socket not only can be used for the power supply control of illuminating lamps, but also is suitable for the power supply control of electric appliances such as TV sets, recorders, electric fans, etc.
Description
The utility model relates to general electronic technology field, belongs to controllable electric power device class.Specifically a kind of sound control of being burst, the alternately supply socket of power on/off.
People in daily life, feeling sometimes must be to the front of electrical equipment and come the work meeting of control apparatus very inconvenient by the switch of pressing electrical equipment.General remote control ask for help again must hold remote controller in the hand, thereby it is very inconvenient also to seem sometimes.Yet make electrical equipment alternately work and quit work by the remote control of sound (as the sound of clapping the hands, fire finger sound etc.), not only bring great convenience, and increased enjoyment for people's life to people's life.Prior art is a kind of lamp holder that is used for controlling the switch of lamp, can not control other electrical equipment easily.As patent CN2050661U " a kind of incandescent lamp holder " with audio-switch.This technology circuit also dislikes complicated in addition, and volume is small and exquisite inadequately, lacks versatility.
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of current collection supply socket is provided, sound control circuit plate and attaching plug be in one, has versatility, and volume is small and exquisite, implement to be easy to the sound control power socket.
Technical solution of the present utility model: mainly by attaching plug, supply socket and sound control circuit plate are formed.The audible signal of bursting (as the sound of clapping the hands, fire finger sound etc.) converts the faint signal of telecommunication to through piezoelectric ceramic piece HTD, and to voltage amplifier, the signal after the amplification removes to trigger flip-flop circuit to this signal, and then triggers controllable silicon through the capacitive coupling of low capacity.Thereby that utilizes the audible signal control socket burst replaces charged and outage.
The utlity model has following advantage:
1) attaching plug, sound control circuit, the supply socket Trinity, thus make sound control power socket overall structure light and practical.
2) owing to used a slice universal integrated circuit just to finish whole controlled function, thereby integrated circuit is simple especially, implements easily.
3) not only lamp can be controlled, and opening and closing can be controlled such as the power supply of other household electrical appliance such as television set, recorder and electric fan.
Accompanying drawing 1 is circuit theory diagrams of the present utility model.
Accompanying drawing 2 is a contour structures schematic diagram of the present utility model.Wherein, 1 ┄ plug, 2 ┄, three core sockets, 3 ┄, two core sockets, the transaudient window of 4 ┄, 5 ┄ sound control circuit plates.
The utility model will be further described in conjunction with the accompanying drawings by the following examples.
The sound of bursting converts the faint signal of telecommunication to through HTD, and this signal of telecommunication is bonded to the two-stage voltage amplifier of being made up of U1, U2 and peripheral cell R2--R6, W and C3 through little capacitor C 2 lotus roots.Signal after the amplification is sent into the monostable shaping circuit of being made up of C4, D7 and R7 and U4 behind the U3 isolation buffer.Whenever there being the sound of bursting to send, this circuit is just exported a negative pulse like this, triggers the flip-flop circuit of being made up of U6, U7, R8--R11, D8, D9 and capacitor C 5, C6 thereafter, and it is overturn.When it is output as high level, trigger one-way SCR BCR and make its conducting, thereby socket power is connected by R12.If its output is low level from the high level upset, then controllable silicon turn-offs when the power supply zero passage, thereby makes the socket outage.The purpose that W is set is for adjusting the output level of U2, with the height of control sensitivity.Low-tension supply is by the D5 rectification, and R1, D6 step-down, voltage stabilizing and C1 filtering obtain.
This sound control power socket can resist certain voice, the interference of musical sound, can be by clapping the hands or knocking desktop and control this socket in 5 meters scopes through surveying maximum.
Claims (3)
1, a kind of sound control power socket is made up of attaching plug, supply socket and sound control circuit plate, it is characterized in that: attaching plug, supply socket and sound control circuit plate all Trinity ground, directly be installed in the shell.
2, sound control power socket according to claim 1 is characterized in that making the secondary voltage amplifier with inverter U1 and U2, and with two inverter U5 and U6 and peripheral cell C5 thereof, C6, D8, D9, R8--R11 have formed the bistable circuit that is triggered by unidirectional pulse.
3, sound control power socket according to claim 1, it is characterized in that socket is serially connected in two input power cords appoints on the single line, low-tension supply is by the D5 rectification, and R1 reaches voltage stabilizing didoe D6 voltage stabilizing thereafter and obtains through capacitor C 1 filtering, and the anode of D5 is connected on before the socket.
