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.
