Laser marking musical instrument teaching system and laser marking musical instrument teaching method based on spherical ultrasonic motor

Abstract

The invention relates to a laser marking musical instrument teaching system and a laser marking musical instrument teaching method based on a spherical ultrasonic motor. The teaching system comprises a music signal acquisition end, a single chip microcomputer system and a laser projector based on the spherical ultrasonic motor. The laser projector based on the spherical ultrasonic motor comprises the spherical ultrasonic motor and a laser source. The music signal acquisition end acquires and processes music signals, and the single chip microcomputer system is controlled by control signals through wireless communication to regulate the spherical ultrasonic motor so as to drive the laser source to generate ordered laser projection signals for instructing playing of musical instruments. The teaching method includes original alignment, music signal acquisition and recognition and laser projection teaching. The teaching system is various in teaching modes, small in volume and convenient to carry, and does not need to be installed on musical instruments, structures of the musical instruments do not need to b changed. The teaching method is simple and easy to learn, strong in maneuverability, suitable for users of different ages and different musical instrument playing levels, wide in application range and capable of being used for teaching different musical instruments.

Description

technical field [0001] The invention relates to a musical instrument teaching system and teaching method, in particular to a laser marking musical instrument teaching system and teaching method based on a spherical ultrasonic motor. technical background [0002] Musical instruments are loved by the general public, but for novices, musical instrument playing training takes a long time and is expensive; for teachers, the traditional teaching mode is inefficient, so the development of an intelligent teaching system is necessary. U.S. Patent US20120064498A1 reports an interactive musical instrument teaching system based on a computer. It consists of a musical instrument, an interface, and a computer. A visual marker needs to be embedded in the musical instrument. The computer receives the interface signal through the software and gives the teaching control signal at the same time. , to control the visual marker inside the musical instrument, to provide visual signal prompts for ...

AI Technical Summary

Problems solved by technology

Since the visual indication signal is not accurately displayed on the keys of the instrument, it is necessary to artificially correspond the signal indication to the corresponding key during the playing process, which increases the difficulty of learning for the player.

In addition, such an implementation also requires a large number of indicator lights to be embedded on the surface of the musical instrument, which is difficult to be widely used in existing musical instruments.
