Introduction The guitar’s quality is directly affected by chords’ thickness, density, length and speakers’ materials and shape.
This paper assumes guitar speaker’s structure and materials are ideal value, only having finite element analysis on chords, on the basis of chords vibration theory analysis, using the finite element method to analyze the chords inherent frequency, and compared with the theory the results.
