Abstract
The invention discloses a low-voltage direct current metronome, comprising a shell, a buzzer module, a booster discharge module, a battery module and a charging interface module, wherein buzzer sound production holes are formed on four sides of the shell; a portable handle is arranged at the top of the shell; the buzzer module, the booster discharge module, the battery module and the charging interface module are arranged inside the shell, and are connected in sequence; a power switch and a charging interface are arranged on the back of the shell. After power is turned on, the battery module supplies power to the buzzer module via the booster discharge module, and a buzzer produces beat sound, which is emitted from the sound production holes on the four sides of the shell of the low-voltage direct current metronome; and when the power switch is turned off, the battery module is charged by the charging interface module on the back of the shell. The low-voltage direct current metronome has the advantages that the battery module is charged to store energy, power is supplied to the buzzer module via the booster discharge module, and the buzzer module produces beat sound; and the low-voltage direct current metronome is small in size, light in weight, small in space occupation, portable, environment-friendly, safe and rechargeable.
