Abstract
The utility model discloses an electromagnetic acoustic-optic metronome which is used for teaching music, and training rhythm. The electromagnetic acoustic-optic metronome is characterized in that a beat pulse generating circuit is connected with an electromagnetic oscillation circuit, and an electromagnetic pendulum swings together with rhythms under the action of the electromagnetic oscillation circuit. Thus, except that the electromagnetic acoustic-optic metronome can display acoustic and light, meanwhile, the electromagnetic acoustic-optic metronome has visibility and continuity, and is a good appliance for music rhythm training, and music learners.
Description
The utility model is a kind of metronome that is used for music teaching and rhythm training.
Metronome before the utility model comes out, only can show interrupted sound and light, beat does not have continuity and visuality, therefore, seldom adopt the metronome of this form, often still adopt the metronome of mechanical pendulum Mainspring type for general music organization and individual, this metronome, though possess visuality and continuity, there is because power adopts clockwork spring drawback such as its rhythm instability, beat adjustment trouble, sound are light.
The purpose of this utility model is to make a kind of metronome that can possess sound, light, pendulum function simultaneously.
The utility model is to have to connect an electromagnetic oscillation circuit on sound, the metronomic clock pulse generation of the light function circuit, with the triangle wave voltage in the clock pulse generation circuit, convert triangular current to a voltage follower, remove to drive an electromagnetic pendulum, the sound, light, the pendulum that make it entire circuit carry out synchronously.
The utility model is compared with other metronome, can possess sound, light, pendulum simultaneously, and timing is strong, and has the visuality and the continuity of beat, is fit to music rhythm training and teaching and uses.
Specific implementation of the present utility model provides with reference to accompanying drawing.
Accompanying drawing is the electrical schematic diagram of one of the utility model embodiment.(1) in the accompanying drawing is power circuit, and (2) are clock pulse generation circuit, and (3) are that acousto-optic drives the generation circuit, and (4) are the electromagnetic oscillation circuit.(U) in electromagnetic oscillation circuit (4) is voltage follower, used herein is LM324 four high guaily unit integrated circuit, it converts the triangle wave voltage of clock pulse generation circuit (2) to triangular current, drives electromagnetic pendulum (G), and what electromagnetic pendulum (G) adopted here is common galvanometer.It connects resistance R
