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.

Embodiment 1

[0072] The laser projection device used is composed of a laser source, a steering gear, and a plane mirror.

[0073] Because the range that the piano needs to indicate is relatively large, two sets of laser projection devices can be used. Since both have a single-chip computer system, information transmission can be carried out between these two sets of laser projection devices.

[0074] The steps of the laser marking keyboard instrument teaching system of the present invention to the piano teaching are as follows:

[0075] 1. Initial positioning

[0076] like Figure 5 As shown, the user selects the musical instrument to be taught as a piano in the software interface. The laser teaching system of the present invention provides the placement position and height of the laser projection device, and the user can place the laser projection device according to the given position. The device and the teaching system will correct the offset of the coordinates according to the placem...

Embodiment 2

[0098] A laser projection device composed of a laser source 1, a driving circuit, a polarizer 6, and a prism 7.

[0099] The initial positioning, collection and recognition of music signals by the smart mobile terminal, and angle calculation are the same as in Embodiment 1, and the projection control is different from Embodiment 1.

[0100] like Figure 9 As shown, in the laser projection device composed of laser source 1, drive circuit, light deflector 5, and prism 6, since the angle that the light deflector 5 can actually deflect is relatively small, three laser sources 1 and three light deflectors can be used. 5, and through the refraction of the prism 6, the orientation of the light projection can be relatively divergent, so as to cover the entire keyboard of the piano. The corresponding relationship between the coordinates and the deflection angle can be according to Step 4 of Embodiment 1. The mobile intelligent terminal generates a control signal and transmits it to th...

Abstract

The invention relates to a teaching system and a teaching method of a laser identification keyboard music instrument. The teaching system comprises a mobile intelligent terminal, a singlechip system and a laser projection device, wherein the mobile intelligent terminal is used for acquiring and processing music signals and controlling the singlechip system to adjust the laser projection device through wireless communication, and then laser projection signals for indicating the play of the music instrument are generated in sequence; the teaching method comprises steps of initial positioning and correction of the keyboard music instrument, the acquisition and identification of music signals and the laser projecting teaching. The teaching system is various in teaching modes, needs not to be installed on the music instrument, is small in size and convenient to carry; a structure of the music instrument needs not to be changed; the teaching method is simple, easy to learn, strong in operability and is applicable to users of different ages and different music instrument playing levels, and is wide in application range.

Description

technical field [0001] The invention relates to a musical instrument teaching system and a teaching method, in particular to a laser marking keyboard musical instrument teaching system. 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 US 20120064498A1 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 at the same time. Signals control the visual markers inside the musical instrument to provide visual signal prompts for the user's performance, so as to achieve the teach...
