OPTICAL MODULE AND OPTICAL DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240280803 titled 'OPTICAL MODULE AND OPTICAL DEVICE

The abstract describes an optical module with a translucent portion, a tubular vibrator supporting the translucent portion, a piezoelectric element to vibrate the vibrator, and an inner-layer optical component at the inner side of the vibrator. The translucent portion has a recess with a curvature facing the inner-layer optical component, and the inner-layer optical component includes an inner-layer lens with a protruding first portion towards the translucent portion and a second portion at the outer periphery of the first portion. Gaps are present between the first portion and the translucent portion, as well as between the second portion and the translucent portion.
