Problems solved by technology

[0003] There are currently many methods for detecting the movement of a key and the speed of a key, and there are other methods of capturing data on the expressiveness of notes on the keyboard of a certain musical instrument. These methods are implemented by means of a mechanical switch structure. The method of using mechanical sensing has many obvious disadvantages, for example, there is no change in sensing, and the control after touching the key is unpredictable, etc.
In addition, this type of switch will affect the feel of the keys when playing, and the installation is also time-consuming, requiring very complicated vertical and horizontal adjustments

Embodiment Construction

[0017] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] figure 1 A schematic diagram showing the installation of optical sensor rails in the piano recording system of the present invention, including keys 101, photoelectric sensors 102, PCB circuit boards 103, sensor rails 104, stretchable cables 105 and PCB circuit board fixing screws 106 .

[0019] The system uses photoelectric sensors to capture data on the movement and movement speed of the keys contained in the music data. An optical sensor is installed under each key of the piano keyboard. A photoelectric sensor corresponds to a key. The optical sensor is an electronic component composed of a light-emitting diode and a phototransistor. Light, the emitted light is reflected back when it encounters the bottom surface of the key, the reflected light will be detected, and the proportional light will be converted into the voltage output by the photo...

Abstract

The invention discloses a recording system of a piano. The recording system comprises a main control box and a sensor guide rail, wherein a sensor interface and a universal serial bus (USB) interface are arranged on the main control box; and the sensor guide rail is connected with the sensor interface on the main control box through a ribbon cable. A photoelectric sensor arranged below a keyboard of an acoustic piano is used for sensing and distinguishing different musical notes and expressive force data of the musical notes, recording the captured processes of the different musical notes and the expressive force data of the musical notes and storing the captured processes into a device which is connected with the USB interface. The recording system of the piano is simple in structure, low in cost and suitable for all types of pianos, and the photoelectric sensor is convenient to assemble.

Description

technical field [0001] The invention relates to the technical field of recording, in particular to a piano recording system. Background technique [0002] The piano is the king of musical instruments. With the development of electronic technology, especially the widespread application of microcomputers, the piano not only maintains the original traditional advantages, but also endows it with many functions, so as to meet the multi-level needs of people's appreciation, practice, and teaching. . [0003] There are many methods for detecting the movement of a key and the speed of a key, and there are other methods of capturing the expressiveness data of the keyboard notes of a certain musical instrument. These methods are realized by means of a mechanical switch structure. The method of using mechanical sensing has many obvious disadvantages, for example, there is no change in sensing, and the control after touching the key is unpredictable. In addition, this type of switch w...
