Abstract
A light-activated acoustic resonator and associated methods are described herein. One embodiment measures the level of ambient light in the environment of the light-activated acoustic resonator; causes a moveable member of an electromagnet disposed within a Helmholtz resonator of the light-activated acoustic resonator to be in an extended position that places the Helmholtz resonator in a first acoustic state, when the level of ambient light is less than a predetermined amount; and causes the moveable member to be in a retracted position that places the Helmholtz resonator in a second acoustic state different from the first acoustic state, when the level of ambient light is at least the predetermined amount.
