Abstract

The utility model discloses an electric metronome. The electric metronome comprises a housing, a pendulum bob observation window, an electric pendulum bob module, a motor module and a power source module; the front surface of the housing is provided with the pendulum bob observation window made of a transparent plastic material; sounding holes are formed at two sides of the housing; the housing is internally provided with the electric pendulum bob module, the motor module and the power source module; the electric pendulum bob module, the motor module and the power source module are successively connected; and the back surface of the housing is provided with a power source switch and a power source line. After the metronome is energized, the power source module supplies power for the motor module, a motor drives the electric pendulum bob module and enables a pendulum bob to swing, the pendulum bob swings to emit beat sound, and the sounding holes at the two sides of the housing of the electric metronome emit the beat sound. The electric metronome has the following advantages that: a power source is continuously supplied for the metronome; and the metronome can carry out sounding operation for a long time in an electric mode.

Description

A kind of electronic metronome

Technical field

The present invention relates to a kind of electronic 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, electronic 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 electronic 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 electronic 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 electronic metronome housing both sides.

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

As a kind of technical scheme, power module uses transformer alternating blood pressure lowering.

As a kind of technical scheme, power module voltage output value uses 5 volts.
