Embodiment Construction

[0032] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection of the present invention are not limited thereto.

[0033] Such as figure 1As shown, it is a workflow flowchart of training and judging the neural network of sound quality with a piano of known sound quality level. Choose a quiet environment such as indoors, and place several pianos. The same player plays the specified melody sequentially on pianos with different levels of sound quality. The microphone matrix is ​​moved in sequence to make it fixed relative to the piano being played each time, and start to pick up sound. Next, the sound signals picked up by the microphone matrix are amplified, filtered, and analog-to-digital converted by the single-chip processing module to generate digital signals that are convenient for research and analysis, and are classified and marked according to the different rec...

Abstract

The invention provides a modern electronic organ manufacturing method based on a loudspeaker array design. The method adopts a microphone matrix to pick up pianos with different levels of sound quality; sound signals are converted into digital signals through a microphone and a single-chip microcomputer; and an extracted characteristic value is used as a data set of the known tone quality level and is used for training s neural network model for training and evaluating the piano sound quality. Then, the numbered three-dimensional loudspeaker arrays of different types are arranged in a combinedmode in a resonant cavity of the modern electronic organ; through a control module, a single-chip microcomputer, a driver and a relay, a relay controls the loudspeaker array combination to be played,the same melody is played, the same microphone matrix is used for picking up, and an array sample is input into a neural network for scoring, and an optimal loudspeaker array design scheme is obtained so as to guide manufacturing of the modern electronic organ.

Description

technical field [0001] The invention relates to the design of the speaker array of the modern electronic organ, in particular to a method for improving the sound quality of the electronic organ by designing the arrangement of the speaker array of the modern electronic organ. Background technique [0002] With the continuous improvement of my country's music education awareness and the improvement of people's living standards, more and more people have sprouted the idea of ​​learning qin instruments, and many schools also hope to open courses in related fields to popularize the beauty of qin music to the public . The piano is known as the "King of Musical Instruments", and it has outstanding performance in full-band sound quality playback, richness of appreciation experience, sense of space, and expression of performance skills. However, limited by various practical conditions such as price, space, maintenance cost, and mobile convenience, there are certain practical difficul...
