PROBLEM TO BE SOLVED: To obtain enriched harmonic, reverberant sound, and sound volume of an acoustic guitar.SOLUTION: An acoustic device includes a columnar acoustic control rod provided in an interior side plate of an acoustic guitar body, so that convexoconcave is formed. Since the surface area of the interior side plate of the body is triangular prism and becomes 1.4 times or more, a reflective surface of sound is enlarged, sound effect is improved by diffusion and echo of sound by the shape, arrangement, and angle of the acoustic control rod. Moreover, harmonic, reverberant sound, and sound volume are enriched.SELECTED DRAWING: Figure 1 |
