Image-capturing apparatus with asymmetric vibration element

摘要

An image-capturing apparatus including an imaging device to convert light into an electrical signal; a vibration plate disposed in front of the imaging device to transmit the light to the imaging device; a vibration generating unit mounted on the vibration plate and to generate a vibration when a driving signal is input to the vibration generating unit; and a vibration partitioning unit mounted on at least one of the vibration plate or the vibration generating unit to asymmetrically deliver the generated vibration to the vibration plate.

1. An image-capturing apparatus comprising:
an imaging device to convert light into an electrical signal; a vibration plate disposed in front of the imaging device to transmit the light to the imaging device; a vibration generating unit mounted on the vibration plate to generate a vibration when a driving signal is input to the vibration generating unit; and a vibration partitioning unit mounted at a location asymmetrically offset from a symmetry line on at least one of the vibration plate or the vibration generating unit so as to divide an edge of the vibration plate or vibration generating unit into first and second sides such that vibrations imparted to the first side generate a first vibrational mode and vibrations imparted to the second side generate a second vibrational mode in the vibration plate, wherein displacements associated with the first and second vibrational modes overlap so as to remove nodes from the resulting vibration of the vibration plate.
