    • PROBLEM TO BE SOLVED: To provide an ukulele which outputs sound traveling far, is hardly affected by humidity and temperature, then, maintains musical performance ability without requiring measure for storing. SOLUTION: A method of manufacturing the ukulele comprises the steps of: forming a scrap wood block 3 of a rectangular object by stacking a scrap wood 1; creating a body 7 in which a rear face and a side face are formed in one unit to a predetermined curved face shape, by hollowing out the scrap wood block 3; fixing a sound board 11 in which a hole 13 is provided on a surface of the body 7; and attaching a neck 15 and a head 17 in which strings 21 are stretched on the body 7. Since a wall face of a round-back member 9 composing the body 7 is formed by hollowing out, it becomes a comparatively thick state, forming an echo material to a vibration wave. When a sound wave hits the wall face of the round-back member 9, the wall face reflects almost all sound waves to a free end, and the sound is echoed. The echoing is repeatedly performed in space of the body 7, to make a resonance wave in which reflective waves are combined. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:为了提供输出远远的声音的ukulele,几乎不受湿度和温度的影响,从而保持音乐表演能力,而不需要存储的措施。 解决方案:一种制造ukulele的方法包括以下步骤:通过堆叠废木1形成矩形物体的废木块3; 通过对废木块3进行挖空,形成一个单元中的后表面和侧面形成为预定的曲面形状的主体7; 固定在主体7的表面上设置孔13的声音板11; 并且将颈部15和头部17附接到其中,其中绳子21在主体7上被拉伸。由于构成主体7的圆形构件9的壁面通过挖空而形成,因此变成较厚的状态,形成 回波材料到振动波。 当声波撞击回圆构件9的壁面时,壁面将几乎所有的声波反射到自由端,并且声音被回送。 回波在主体7的空间中重复进行,以形成其中组合反射波的共振波。 版权所有(C)2010,JPO&INPIT
