Abstract

The invention discloses a low-power-consumption electronic metronome comprising a shell, a pendulum bob observation window, an electric pendulum bob module, a motor module, and a power module. The pendulum bob observation window made of a transparent plastic material is arranged at the front side of the shell; and sound production holes are formed in the two sides of the shell. The electric pendulum bob module, the motor module, and the power module are arranged installed inside the shell and are successively connected; and a power switch and a power line are arranged at the back of the shell. After power connection, the power module provides power for the motor module; the motor drives the electric pendulum bob module and enables the pendulum bob to oscillate; the pendulum bob oscillates to make beat sound; and then the beat sound is sent out from the sound production holes of the two sides of the shell of the electronic metronome. According to the invention, the low-power-consumption electronic metronome has the following advantages: power can be provided for the metronome continuously; the metronome can carry out sounding work for long time by an electric way; and the electronic metronome has characteristics of low power consumption and energy conservation.

Description

A kind of low power dissipation electron metronome

Technical field

The present invention relates to a kind of low power dissipation electron metronome, belong to vocal music and musical instrument exercise utensil technical field.

Background technology

The happy musical instrument exercise metronome of conventional acoustic, use machinery clockwork spring as pendulum power source, practitioner needs interval twisting clockwork spring to keep pendulum strike work, pendulum Impulse time persistence is limited, low power dissipation electron metronome uses power supply to power, and pendulum can be kept to hit work for a long time, continuously send out metronome, practitioner is helped to concentrate one's energy to continue to practise, it is to avoid the out-of-work puzzlement of metronome.

Summary of the invention

It is an object of the invention to provide a kind of low power dissipation electron metronome, the effect reaching to send metronome can keep again working long hours.

It is an object of the invention to be achieved through the following technical solutions:

As a kind of technical scheme, a kind of low power dissipation electron metronome, including: housing, pendulum observation window, electronic pendulum mass module, motor module, power module, described housing front has transparent plastics material pendulum observation window, there is vocal hole housing both sides, enclosure interior is equipped with electronic pendulum mass module, motor module, power module, and electronic pendulum mass module, motor module, power module are sequentially connected, and back side of shell has on and off switch and power line. After switching on power, electric power source pair of module motor module is powered, and motor drives electronic pendulum mass module and makes pendulum swing, and pendulum swings and sends metronome, sends metronome from the vocal hole of low power dissipation electron metronome housing both sides. Advantage of the present invention provides constant current source for metronome, provides metronome long-time sounding work in electronic mode.

As a kind of technical scheme, electronic pendulum mass module uses motor to drive.

As a kind of technical scheme, power module uses decompression capacitor blood pressure lowering.

As a kind of technical scheme, power module voltage output value uses 3.6 volts.
