Problems solved by technology

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, etc.

Abstract

The invention relates to a sensing type piano recording technical scheme. The sensing type piano recording technical scheme is characterized in that a recording device comprises a main control box anda sensor guide rail, the main control box is provided with a sensor interface and a USB interface, and the sensor guide rail is connected with the sensor interface on the main control box through a strip-shaped cable; four PCBs are mounted on the sensor guide rail, and each PCB is provided with 22 photoelectric sensors; the PCBs are connected with telescopic flexible flat cables; the main controlbox is connected with a computer installed with a recording software system through the USB interface and outputs data to the computer; the upward face of each photoelectric sensor is provided with alight-emitting diode and a phototransistor. The sensing type piano recording technical scheme has the advantages that the technical scheme is convenient in operation and simple in principle, the system can precisely capture a playing process by the aid of the high-sensitivity photoelectric sensors, and each moment of the playing can be precisely recorded and flexibly saved.

Description

Technical field [0001] The present invention relates to the technical field of recording, in particular to a piano recording system, and in particular provides a technical solution for inductive piano recording. Background technique [0002] The piano is the king of musical instruments. With the development of electronic technology, especially the general application of microcomputers, the piano is endowed with many functions while maintaining the original traditional advantages, so as to meet the multi-level needs of people's appreciation, practice, and teaching. . At present, there are many methods for detecting the movement of a key and the speed of movement of a key. There are also some other methods of capturing the expressive power data of a certain musical instrument keyboard. These methods are realized by using a mechanical switch structure. The method of using mechanical induction has many obvious shortcomings, for example, the induction does not change, and the control...
