Control method for enabling LED lamp to flash along with music and music rhythm flashing lamp

The invention discloses a control method for enabling an LED lamp to flash along with music and a music rhythm flashing lamp. The control method comprises the steps that firstly, a microphone receives acoustic waves and ultrasonic waves; secondly, an ultrasonic wave detecting circuit receives ultrasonic waves sent by the microphone, and when the ultrasonic wave at a specific frequency is received, an electrical signal is generated; thirdly, a master control circuit enables a signal amplifying circuit to be closed and controls the ultrasonic wave detecting circuit to be in the dormant state at the same time; fourthly, acoustic waves received by the microphone are converted into electrical signals by the signal amplifying circuit, wherein the acoustic waves at different frequencies are converted into different electrical signals; fifthly, the master control circuit controls shining and extinguishing of the LED lamp according to the electrical samples obtained in the fourth step. By the adoption of the control method for enabling the LED lamp to flash along with music, the LED lamp can be automatically turned on through the ultrasonic wave at a specific frequency, the LED lamp can shine, be extinguished and change brightness along with change of the frequency of the acoustic wave, and therefore the purpose that the LED lamp flashes along with music is achieved.

Electronic metronome

The invention discloses an electronic metronome which comprises a singlechip, a voice chip, a loudspeaker, a power supply interface, a button switch and at least three laser diodes, wherein the singlechip is connected with the power supply interface, the voice chip and the button switch, the laser diodes are respectively connected with a resistor and the singlechip through a triode. According to the electronic metronome, through the laser diodes arranged at different positions, and under the control of the singlechip, beat movements of an oscillating bar of a mechanical metronome can be simulated by lasers, and also can be edited, modified and selected directly or by remote control according to the beat time sequence requirement, thus people which are accustomed to the beat movements of the oscillating bar of the mechanical metronome can feel harmonic when using the electronic metronome, and the beat movements of the oscillating bar of the mechanical metronome, which are simulated by lasers, are large in movement range and are glaring. The laser simulated oscillating bar which is large in beat movement range and is glaring has the advantages that the visual effect is improved, the beat sense is intensified, the atmosphere is activated, and the application ranges of the electronic metronome is expanded.
