Abstract
The utility model discloses a kind of electronic metronome, comprise: housing, pendulum view window, electronic pendulum mass module, motor module, power module, described housing front has transparent plastics material pendulum view window, there is vocal hole housing both sides, enclosure interior is equipped with electronic pendulum mass module, motor module, power module, electronic pendulum mass module, motor module, power module are connected successively, and back side of shell has power switch and power lead.After switching on power, electric power source pair of module motor module is powered, and motor drives electronic pendulum mass module and pendulum is swung, and pendulum swings and sends metronome, sends metronome from the vocal hole of electronic metronome housing both sides.The utility model advantage provides constant current source for metronome, provides metronome long-time sounding work in electronic mode.
Description
Technical field
The utility model relates to a kind of electronic metronome, belongs to vocal music and musical instrument exercise utensil technical field.
Background technology
Conventional acoustic happy musical instrument exercise metronome, use mechanical clockwork spring as pendulum power source, practitioner needs interval to twist clockwork spring to keep pendulum strike work, pendulum Impulse time continuation is limited, electronic metronome uses Power supply, pendulum can be kept to hit work for a long time, continue to send metronome, help practitioner to concentrate one's energy to continue exercise, avoid the out-of-work puzzlement of metronome.
Summary of the invention
The purpose of this utility model is to provide a kind of electronic metronome, reaches the effect sending metronome and can keep again working long hours.
The purpose of this utility model is achieved through the following technical solutions:
As a kind of technical scheme, a kind of electronic metronome, comprise: housing, pendulum view window, electronic pendulum mass module, motor module, power module, described housing front has transparent plastics material pendulum view 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 connected successively, and back side of shell has power switch and power lead.After switching on power, electric power source pair of module motor module is powered, and motor drives electronic pendulum mass module and pendulum is swung, 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 step-down.
As a kind of technical scheme, power module voltage output value uses 5 volts.
