Abstract
The utility model discloses an electric metronome to solve the problems that the conventional metronome has errors in swing and has short service life. The electric metronome comprises a housing. The housing includes a front cover and a rear cover. A stepping motor is fixed in the rear cover. A rotation shaft of the stepping motor is fixedly connected with a pendulum bob. The stepping motor is electrically connected with a control circuit fixed in the rear cover. The control circuit board controls the stepping motor to rotate so as to enable the pendulum bob to swing without errors. The control circuit board is also connected with a battery. The battery is used for providing power for the stepping motor, so that the metronome can operate for a long time. The electric metronome is further provided with control buttons and a display screen, so that users can simply and directly operate the electric metronome.
Description
Technical field
The utility model relates to a kind of motor metronome.
Background technology
Traditional mechanical metronome is because the clockwork spring in going barrel is inhomogeneous in the time that energy discharges, thereby the number of times that fork per minute is swung exists error.Gear in tradition mechanical metronome and rotating shaft are due to the problem of machining precision, and also ubiquity error.Under the accumulation of error, mechanical metronome cannot accomplish that 100% is accurate.Metronome itself is to have the very music teaching supplementary instrument of pin-point accuracy, and so large error can be brought great puzzlement to teaching.Traditional metronome, because clockwork spring is limited, often only has more than 10 minute service time and just will again wind up, and has brought trouble to use.When mounted, due to high to accuracy requirement, difficulty is installed, and also has a kind of electronic metronome of electronic slide block type, horizontally slipping is visually unfavorable for using and learning, and long-time use also there will be serious wearing and tearing, affects metronomic serviceable life.
Utility model content
The purpose of this utility model be to provide a kind of motor-driven, swing error free, simple metronome is installed.
For reaching this object, the utility model by the following technical solutions:
A kind of electronic metronome, comprise shell, described shell comprises protecgulum and bonnet, described protecgulum and bonnet clamping, be fixed with stepper motor in described bonnet, in the rotating shaft of motor, is fixed with pendulum, described stepper motor is electrically connected with the control circuit board being fixed in bonnet, the outside of bonnet offers the battery compartment for placing battery, and described battery and control circuit board are electrically connected, and the front surface of described protecgulum is provided with indicating graduation chi.
Further, described control circuit is also powered with loudspeaker, and described loudspeaker is fixed in the pickup groove that bonnet offers, and the outside of pickup groove offers vocal hole.
Further, described protecgulum comprises the bossing of lower end and the female parts of upper end, and described indicating graduation chi is arranged on female parts front surface, and the groove that the upper end of described pendulum is offered through the bossing upper end of protecgulum vertically arranges.
Further, the front surface of the bossing of described protecgulum is provided with display screen and control knob, and described display screen and control knob and control circuit board are electrically connected.
Further, described pendulum is flat structure, and the pendulum head of described pendulum is hexagon.
The beneficial effects of the utility model are: described electronic metronomic pendulum drives by stepper motor, by battery-operated, and sustainable use, and stepper motor rotates control pendulum and swings error free, in addition, described metronome is provided with display screen and control knob, person's operation easy to use.
