The high-frequency vibration nicking device for microbead surfaces includes a high-frequency vibration assembly and a container. Microbeads or mixed materials of the microbeads and a grinding material are filled in the container, and the vibration output end of the high-frequency vibration assembly is connected with the container to perform high-frequency vibration on the microbeads. The high-frequency vibration nicking method for microbead surfaces includes steps of adding the microbeads into the container, turning on the high-frequency vibration assembly, and performing high-frequency vibration motion on the microbeads in the container under the action of the high-frequency vibration assembly. According to the device and the method, the high-frequency vibration assembly generates high-frequency vibration to drive the microbeads to perform high-frequency vibration motion in a limited space, so that mutual collision and friction are generated among the microbeads, between the microbeads and the container wall and between the microbeads and the vibrating body.

Deadfront articles that include a tactile element formed on a first surface of a substrate and a visual element disposed on a second surface of the substrate opposite the first surface. The tactile element is positioned on the first surface of the substrate in a complimentary fashion to the visual element disposed on the second surface of the substrate. The tactile element may include a surface roughness portion having a surface roughness different than the surface roughness of an area bordering the surface roughness portion. The deadfront articles may be incorporated into an automobile interior to provide a visual and haptic display interface for a user.
