A vibration plate for a musical instrument includes: a plate-shaped vibration plate main body that has a deformation anisotropy property; a first elongated reinforcing member disposed on a first face of the vibration plate main body, and that projects outwardly from the first face and extends along the first face in a direction that prevents the vibration plate main body from deforming; and a second elongated reinforcing member disposed on a second face of the vibration plate main body, and that projects outwardly from the second face and extends along the second face in the direction that prevents the vibration plate main body from deforming. As viewed from a thickness direction of the vibration plate main body, at least part of the first elongated reinforcing member overlaps with at least part of the second elongated reinforcing member.

Vibration plate and musical instrument

Provided is a musical instrument including a vibratable body; and a vibrator. The vibrator includes a vibrating body that vibrates in a predetermined direction; and a coupling member coupling the vibrating body and the vibratable body and that transmits vibration of the vibrating body to the vibratable body. The coupling member includes a shaft extending between the vibrating body and the vibratable body; a first wire rod coupling one end portion of the shaft and the vibrating body; and a second wire rod coupling another end portion of the shaft and the vibratable body. A resonance frequency of each of the shaft, the first wire rod, and the second wire rod is at least 10 kHz.

Musical instrument and vibrator

A vibrator includes: a movable portion connected to a vibratable member; a driver configured to drive the movable portion to cause vibration of the movable portion to vibrate the vibratable member; and a driver supporter secured to a support member and configured to support the driver such that the driver is pivotable about an axis extending in a direction intersecting a movable direction of the movable portion.

Vibrator and musical instrument

A shell for drum according to the present invention includes a laminated plywood-panel including a plurality of single-panels having different densities, the plurality of single-panels being jointed in decreasing order of density from a center portion in a thick direction of the laminated plywood-panel toward an outermost portion and an innermost portion, such that a single-panel having a highest density is arranged at the center portion, and single-panels having lowest densities are arranged at the outermost portion and the innermost portion.
