Abstract: An engraving device includes a material processing platform disposed on a base frame and including suction holes and a pneumatic joint communicating with the suction holes; a gantry bracket disposed across both sides of the base frame; a spindle motor disposed on the gantry bracket; a processing bit operatively connected to the spindle motor; a dust collector disposed on the processing bit; and a driving mechanism operatively connected to the spindle motor and configured to move along the X-axis, Y-axis, and Z-axis.

Abstract: A light speaker structure with a ring handle includes a speaker body, a speaker enclosure, a lighting mechanism and an auxiliary mechanism. The speaker body is mounted within the speaker enclosure, and the auxiliary mechanism is mounted on the speaker enclosure. The lighting mechanism includes a lampshade, a light strip, and LED beads. The light strip is mounted within the lampshade. The LED beads are fixedly connected to the light strip and electrically connected to the speaker body. The light strip is disposed in a laterally inverted C-shape around the speaker enclosure. The lampshade covers the light strip, so that the light strip is held between the lampshade and the speaker enclosure. The light strip and the lampshade are so shaped that they can be arranged around the speaker enclosure, thereby achieving a better lighting effect, providing a larger lighting area and producing a stereoscopic effect.
