  • Publication number: 20040083873
    Abstract: An object of the present invention is to provide a percussion detecting apparatus, which is excellent in percussion feeling, and the percussion sounds of which are very small, in electronic percussion instrumental system. The percussion detecting apparatus is provided with a head prepared from a net-like raw material composed of a first net and a second net, the net-like raw material being obtained by such a manner that both the nets having been woven in accordance with plane weaving manner wherein the longitudinal and transverse fibers cross at right angles are laminated in such a way that the weave pattern directions thereof intersect obliquely with each other; and a head sensor which is in contact with the center position of the under side in the head and detects percussion with respect to the head as electric signal.
