Infrared-triggered multimedia music book turning machine of piano

Abstract

The invention discloses an infrared-triggered multimedia music book turning machine of a piano, wherein an infrared triggering mechanism is in radio connection with a controller, the controller is connected with a display driving unit, and the display driving unit is connected with a memory and a display through data transmission lines; the infrared triggering mechanism comprises two telescopic brackets, each telescopic bracket is provided with a main bracket, an auxiliary bracket I and an auxiliary bracket II; a guide hole is arranged on the main bracket, and a clip plate I is arranged on the top end of the main bracket; the auxiliary bracket I and the auxiliary bracket II are respectively connected with the main bracket through locking bolts in the guide hole, a clip plate II is arranged on the auxiliary bracket I, a cantilever is arranged on the lower end of the clip plate II, and an infrared receiver is arranged on the lower end of the cantilever; a corresponding infrared emitter is arranged on the bottom end of the auxiliary bracket II, a sampling circuit in the infrared receiver is connected with a radio emitting unit, and the radio emitting unit is in radio connection with a radio receiving unit arranged in the controller. The infrared-triggered multimedia music book turning machine of piano has the advantages of turning the music book forward and backward, and having smart and adjustable structure, convenience for installation and flexible operation.

Description

technical field [0001] The invention relates to an electronic device used in piano performance to automatically flip through music scores, specifically an electronic device used in piano performance, which generates control signals by blocking infrared rays, and then realizes front and rear page turning of electronic music scores. Background technique [0002] At present, there are some problems in the reading of music scores in piano performances: 1. Most of them use paper scores, which are inconvenient to read. Generally, regular performances will be equipped with special personnel to assist in reading. This is not only a waste of manpower, but also greatly affects show effect. 2. There is also a mechanical sheet-turning machine, which is generally controlled by a foot switch during performance. This kind of device is generally bulky, inconvenient to carry, and not sensitive to operation, which also has a great impact on the fluency of performance. In addition, simila...

Problems solved by technology

[0002] At present, there are some problems in the reading of music scores in piano performances: 1. Most of them use paper scores, which are inconvenient to read. Generally, regular performances will be equipped with special personnel to assist in reading. This is not only a waste of manpower, but also greatly affects performance effect

2. There is also a mechanical sheet-turning machine, which is generally controlled by a foot switch during performance. This kind of device is generally bulky, inconvenient to carry, and not sensitive to operation, which also has a great impact on the fluency of performance. In addition, similar patents that have been approved in the patent library are integrated with the music stand, and the overall volume is large and heavy, which is not suitable for piano performance.

3. There is also an electronic sheet-turning machine, which is similar to a handheld computer. The main disadvantage of this type of equipment is that after the performance starts, all the reading of the sheet music is handed over to the pre-set program for control, so it is not very good. Adapt to special situations that may occur at any time during the performance process, poor adaptability, and this device plays electronic music scores, but the total amount of electronic music scores in the world is not large, so it is often encountered that the track you are playing cannot be found.
