Abstract
The utility model provides a sound control time signal clock, which comprises an electronic sound time signal clock body and a time signal circuit system. The sound control time signal clock characterized in that a sound control circuit is arranged on the switch of the time signal circuit in parallel; the utility model not only avoids the mutual interruption to the roommates, but also plays the role of reminding. It is easy to utilize, helps to upgrade life style and improves working efficiency; the utility model has a simple structure and a low cost and is particularly suitable for students and soldiers who live in collective.
Description
Technical field
The utility model relates to small stores, particularly a kind of timing electronic timekeeping clock.
Background technology
Generally all need turn on light to watch when people awake from sleep when wondering the time evening, if an own solitary Room is not bad, if but indoorly have other people to live together, turn on light and must cause interference to others, influence other people sleep.General clock can't give the correct time very inconvenient at night, does not turn on light and can't see the time, turns on light and bothers other people.
Summary of the invention
In order to change the sorry present situation that above-mentioned clock can't give the correct time at night, the utility model provides a kind of acoustic control time signal clock.
The utility model technical scheme for achieving the above object is as follows: a kind of acoustic control time signal clock, comprise electronic speech time signal clock body and the Circuits System of giving the correct time, and feature is to be parallel with sound control circuit on the switch of its circuit that gives the correct time.
Said sound control circuit comprises Electret condenser microphone, acoustic control flash of light special IC and photoelectrical coupler; Wherein acoustic control flash of light special IC comprises amplification, delay and drive part, photoelectrical coupler comprise the VD light emitting diode and with the switch of the circuit that gives the correct time on RL photo-resistor in parallel.
After Electret condenser microphone receives a voice signal that specific relative frequency is higher, sound is bigger, sound wave is converted to corresponding ultra-weak electronic signal.This signal is luminous through the built-in light emitting diode VD that amplifies, postpones the rear drive photoelectrical coupler, make corresponding photo-resistor RL be low resistance, promptly connect the on-off circuit that gives the correct time, be equivalent to press the contactor that gives the correct time, the circuit that gives the correct time is subjected to trigger and promptly starts working, thereby quotes the instant time in the moment.
The utility model is given the correct time by sound control, and clock is placed on bedside, because with respect to quiet indoor environment, starting the sound that gives the correct time needn't give the correct time in very big enough startups, and the sound that gives the correct time of time signal clock also can be turned the therefore sleep that can not wake up with a start other people down.The utility model had both been avoided the phase mutual interference of chummage rounding off, played reminding effect during postscript, and was easy to use, helped promoting the life grade, the efficient of raising work and life.The utility model is simple in structure, with low cost, and the crowd who is particularly suitable for collective livelihoods such as student, soldier uses.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
Among the figure:
1. amplify, 2. postpone, 3. drive, 4. speaking clock, 5.VD light emitting diode, 6.RL photo-resistor, 7,8. capacitor, 9. give the correct time switch key, 10. Electret condenser microphone, 11. acoustic controls flash of light special IC, 12. photoelectrical couplers.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified:
The utility model acoustic control time signal clock comprises electronic speech time signal clock body and the Circuits System 4 of giving the correct time, and is parallel with sound control circuit on the switch 9 of circuit 4 that gives the correct time.Sound control circuit comprises Electret condenser microphone 10, acoustic control flash of light special IC 11 and photoelectrical coupler 12; Wherein acoustic control flash of light special IC 11 comprises and amplifies 1, postpones 2 and drive 3 several sections, and photoelectrical coupler 12 comprises VD light emitting diode 5 and the RL photo-resistor 6 in parallel with the switch 9 of the circuit that gives the correct time.
(Electret condenser microphone has multiple advantage when Electret condenser microphone 10, be widely used in the circuit such as cassette recorder, wireless microphone and acoustic control) receive a particular sound signal after, sound wave is converted to corresponding ultra-weak electronic signal, through amplify 1, to postpone the built-in light emitting diode VD5 of 2 rear drives, 3 photoelectrical couplers 12 luminous, make corresponding photo-resistor RL6 be low resistance, so just, connected the on-off circuit that gives the correct time, be equivalent to press the contactor 9 that gives the correct time, the circuit 4 that gives the correct time is subjected to trigger and promptly starts working, thereby quotes the instant time.
Claims (3)
1, a kind of acoustic control time signal clock comprises electronic speech time signal clock body and the Circuits System of giving the correct time, and it is characterized in that being parallel with sound control circuit on the switch of its circuit that gives the correct time.
2,, it is characterized in that said sound control circuit comprises Electret condenser microphone, acoustic control flash of light special IC and photoelectrical coupler as the said acoustic control time signal clock of claim 1.
3, as the said acoustic control time signal clock of claim 2, it is characterized in that said acoustic control flash of light special IC comprises amplification, delay and drive part, photoelectrical coupler comprise the VD light emitting diode and with the switch of the circuit that gives the correct time on RL photo-resistor in parallel.
