Abstract
A vibration detection mechanism includes: a first sensor section that detects vibration of a vibrating member of a musical instrument in a first direction being a main vibration direction; a second sensor section that detects vibration of the vibrating member in a second direction being approximately perpendicular to the first direction; and a third sensor section that detects vibration of the vibrating member in a third direction being approximately perpendicular to both the first direction and the second direction. Sensitivity of the second sensor section is greater than sensitivity of the first sensor section. Sensitivity of the third sensor section is greater than the sensitivity of the first sensor section.

A vibration detection mechanism comprising:
- a first sensor section that detects vibration of a vibrating member of a musical instrument in a first direction being a main vibration direction;
- a second sensor section that detects vibration of the vibrating member in a second direction being perpendicular to the first direction;
- and
- a third sensor section that detects vibration of the vibrating member in a third direction being perpendicular to both the first direction and the second direction,
- wherein a sensitivity of the second sensor section that detects vibration of the vibrating member in the second direction perpendicular to the first direction is greater than a sensitivity of the first sensor section that detects vibration of the vibrating member in the first direction being the main vibration direction, and a sensitivity of the third sensor section that detects vibration of the vibrating member in the third direction perpendicular to both the first direction and the second direction is greater than the sensitivity of the first sensor section.
A vibration sensor unit comprising:
- an installation surface for installation on a surface that is of a vibrating member of a musical instrument or a member fixed to the vibrating member and is perpendicular to a first direction being a main vibration direction;
- a first surface that is parallel to the installation surface;
- a second surface that is perpendicular to the first surface;
- a third surface that is perpendicular to both the first surface and the second surface;
- a first sensor section that is installed on the first surface and detects vibration of the vibrating member in the first direction;
- a second sensor section that is installed on the second surface and detects vibration of the vibrating member in a second direction being perpendicular to the first direction;
- and
- a third sensor section that is installed on the third surface and detects vibration of the vibrating member in a third direction being perpendicular to both the first direction and the second direction, and
- wherein sensitivity of the second sensor section is greater than sensitivity of the first sensor section, and sensitivity of the third sensor section is greater than the sensitivity of the first sensor section.
