The present disclosure relates to a 3D integrated imaging device and a preparation method thereof. The 3D integrated imaging device includes a spacer layer, a three-dimensional structure layer, and a microlens array. The spacer layer has a preset thickness. The three-dimensional structure layer is disposed on a surface of a side of the spacer layer and includes a plurality of micro-nano structure units. The microlens array is arranged on a surface of a side of the spacer layer away from the three-dimensional structure layer and includes a plurality of microlenses. The plurality of micro-nano structure units correspond to the plurality of micro-lenses one by one. A front view pattern of the plurality of micro-nano structure units is a superposition of images formed by each layered image of a target stereoscopic image under the plurality of micro-lenses according to different depths of field after the target stereoscopic image is layered.

3D integrated imaging devices and preparation methods thereof

The present invention provides a hearing protection earphone, a hearing protection method and a computer program storage medium, comprising a sound control system including a wearing-status sensing module for monitoring a current wearing status of the hearing protection earphone, sending a first monitoring signal when it is determined that the hearing protection earphone is in a wearing state, and sending a second monitoring signal when it is determined that the hearing protection earphone is in a non-wearing state; and a main control module for enabling a play function corresponding to a play mode which is adapted to the hearing protection earphone currently when the first monitoring signal sent from the wearing-status sensing module is received, and counting a stand-by time of the protection earphone and turning off the hearing protection earphone after a preset stand-by time elapses when the second monitoring signal sent from the wearing-status sensing module is received.
