Description

A low-power electronic metronome

technical field

The utility model relates to a low-power electronic metronome, which belongs to the technical field of vocal music and musical instrument practice equipment.

Background technique

A metronome for ordinary vocal music and musical instrument practice, using a mechanical spring as the power source of the pendulum. Practitioners need to twist the spring at intervals to keep the pendulum striking. The duration of pendulum striking is limited. Low-power electronic metronome uses power supply The power supply can keep the pendulum working for a long time and make a continuous beat sound, helping the practitioner to concentrate on continuous practice and avoid the trouble of the metronome stopping working.

Contents of the invention

The purpose of the utility model is to provide an electronic metronome with low power consumption, which can achieve the effect of making beat sound and can keep working for a long time.

The purpose of this utility model is to realize through the following technical solutions:

As a technical solution, a low-power electronic metronome includes: a housing, a pendulum observation window, an electric pendulum module, a motor module, and a power supply module. The front of the housing has a pendulum observation window made of transparent plastic material, There are sound holes on both sides of the shell, and the electric pendulum module, the motor module, and the power module are installed inside the shell, and the electric pendulum module, the motor module, and the power module are connected in sequence. After the power is turned on, the power supply module supplies power to the motor module, and the motor drives the electric pendulum module to make the pendulum swing, and the pendulum swings to make a beat sound, and the beat sound is emitted from the sound holes on both sides of the low-power electronic metronome housing. The invention has the advantages of providing continuous power supply for the metronome, and providing the metronome with sounding work for a long time in an electric manner.

As a technical solution, the electric pendulum module is driven by a motor.
