Energy-saving type acousto-optic electronic alarm clock

Abstract

The invention provides an energy-saving type acousto-optic electronic alarm clock which comprises a control circuit, an infrared sensor, a nixie tube and an acousto-optic alarm clock. The control circuit comprises a switch circuit, a driving circuit and a clock circuit, the infrared sensor controls the switch circuit, the switch circuit controls the acousto-optic alarm clock and the driving circuit, and the clock circuit provides time information to the nixie tube and the acousto-optic alarm clock. When people are nearby the acousto-optic alarm clock, the driving circuit automatically connects the power supply of the nixie tube and the power supply of a music acousto-optic integrated circuit, the nixie tube will display, and hourly chiming can be performed. When no people are available, the energy-saving type acousto-optic electronic alarm clock is turned off automatically, only the clock circuit works, and timing will not be interrupted. Therefore, the function of saving energy can be performed really, the service life of the battery is prolonged, and pollution on the environment by waste batteries is reduced.

Description

technical field [0001] The invention relates to an alarm clock, in particular to an energy-saving acousto-optic electronic alarm clock equipped with an infrared sensor. Background technique [0002] In today's society, time awareness has attracted more and more attention, so digital and LCD electronic clocks abound, especially sound and light alarm clocks, which are cheap and good, but when there is no one, the alarm clock is still on, and the time is still telling the time, causing waste of energy. In this way, how long can a pair of batteries last? No one has considered this aspect, and if the battery is used too much, it will pollute the environment, so it is extremely urgent to study energy-saving electronic clocks. Contents of the invention [0003] The object of the present invention is to provide an energy-saving acousto-optic electronic alarm clock, which solves the problem of unnecessary energy waste of the alarm clock. [0004] In order to solve the above prob...
