Method and apparatus for demonstrating the time by acoustic-optical centripetal mode

Abstract

The invention discloses a sound-light centering mode rhythm-showing method and apparatus in which a frame is configured, electronic circuits of a metronome or a rhythm sound corrector are designed in an inner portion, keystokes and a related segment array of LED or LCD display units which are vertically or horizontally arranged are designed in an outer portion. At a rhythm time of each rhythm / rear half-rhythm time, display light points are fulgurated one by one in an order from a centre to two ends / from thw two ends to the centre, and corresponding sound is synchronously cooperated, thereby forming an intuitionistic effect of simulating clapping hands to show the rhythm. The invention can be directly used in a metronome or a rhythm sound corrector which show the rhythm vertically and horizontally, and is better for music study of children.

Description

technical field [0001] The invention relates to an electronic metronome for music teaching, and more specifically relates to a method and a device for demonstrating beats in an acousto-optic centripetal mode. Background technique [0002] In the prior art, electronic metronomes (including electronic beat tuners) that demonstrate beats with acousto-optic changes usually have two modes of light display, horizontal and vertical, when demonstrating beats: the horizontal demonstration mode actually imitates traditional mechanical metronomes. Demonstration mode - swinging left to the left end is one beat, and swinging right to the right end is one beat. This kind of beat demonstration method has no distinction between front / back half beats and cannot scientifically demonstrate music beats The longitudinal way of showing the beat is to demonstrate the beat with "↓↑" two-way motion (moving down to the end is the first half beat, moving up to the top or the middle is the second half ...

[0002] In the prior art, electronic metronomes (including electronic beat tuners) that demonstrate beats with acousto-optic changes usually have two modes of light display, horizontal and vertical, when demonstrating beats: the horizontal demonstration mode actually imitates traditional mechanical metronomes. Demonstration mode - swinging left to the left end is one beat, and swinging right to the right end is one beat. This kind of beat demonstration method has no distinction between front / back half beats and cannot scientifically demonstrate music beats The longitudinal way of showing the beat is to demonstrate the beat with "↓↑" two-way motion (moving down to the end is the first half beat, moving up to the top or the middle is the second half beat). For example, the patent No. 97225282.7 is open to the public An electronic metronome device that demonstrates beats in the form of "↓↑" is developed. Although this "↓↑" beat demonstration method conforms to the rules of music and music habits, it is too rigorous and blunt for children who are new to music.
