Electronic metronome

Abstract

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.

Description

technical field [0001] The invention relates to an electronic metronome, in particular to an electronic metronome which simulates the movement of a swing rod of a mechanical metronome by laser. Background technique [0002] The electronic metronome of the prior art does not simulate the beat action of the pendulum rod of the mechanical metronome; instead, it uses a light-emitting diode or a liquid crystal display to show the beat action by sequentially lighting up from one end to the multi-end side, and also uses the illumination of the light-emitting element The beat action is reproduced with the change of the beat; therefore, people who are accustomed to the swing stick beat action of a mechanical metronome will feel dissonant when using it. Contents of the invention [0003] The object of the present invention is to provide an electronic metronome, the electronic metronome can use laser to simulate the beat action of the pendulum rod of the mechanical metronome under th...
