Abstract
A vibration detection component includes a diaphragm that has a light transparency; alight emitting element that emits light into the diaphragm at a certain inclination angle relative to a normal direction of the diaphragm; and a light receiving element that receives the light emitted from the light emitting element and reflected by an interface between the diaphragm and a medium in contact with the diaphragm and converts the light into an electric signal related to vibration of the diaphragm.
