Embodiment Construction

[0038] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] The schematic diagram of the overall structure of the detection device corresponding to the method for detecting the timbre of guitar strings based on machine vision in this embodiment is as follows figure 1 shown. The device includes a gripping end 1, a saddle end 2, a saddle end 3 and a stretching end 4. The gripping end 1, the saddle end 2, the saddle end 3 and the stretching end 4 are four points and one line, and the saddle end The end 2 and the saddle end 3 are arranged in parallel, perpendicular to the straight line direction from the holding end 1 to the stretching end 4, and the bridge end 2 moves along the straight line direction from the holding end 1 to the stretching end 4; the string to be tested 5 is fixed at the holding end 1, passing through the bridge end 2, the saddle end 3 to the stretching end 4 in sequ...

Abstract

A method for detecting the timbre of guitar strings based on the first kind of 0-order Bessel function belongs to the field of musical instruments, mechanical equipment and precision instruments; the detection method first adjusts the position of the bridge end (2), and then adjusts the string to be tested ( 5) pitch, then collect the vibration image and obtain the vibration function, and finally compare the vibration function with the evaluation function obtained according to the amplitude of the maximum amplitude position of the string (5) to be tested, and obtain the timbre detection result; the present invention can realize The technical purpose of judging the timbre of the strings by detecting the vibration track of the strings.

Description

technical field [0001] A method for detecting the timbre of guitar strings based on the first-order 0-order Bessel function belongs to the fields of musical instruments, mechanical equipment and precision instruments. Background technique [0002] The guitar, also known as the violin, is a plucked string instrument that is often regarded as the main instrument in pop music, rock music, blues, folk songs, and flamenco. [0003] Since the guitar produces sound by the vibration of the strings, the sound of the guitar depends first on whether the vibration trajectory of the strings is standard. Based on the above analysis, the quality of the guitar tone can be judged by detecting the vibration trajectory of the strings. [0004] Unfortunately, however, no such device or method has been adopted at this stage. Contents of the invention [0005] In order to achieve the purpose of judging the quality of guitar timbre by detecting the vibration of the strings, the present inventi...
