1. A broadband vibration suppression apparatus using an acoustic black hole feature, comprising:
a vibration-reduced body comprising a uniform portion of a fixed thickness and a tapered portion integrally connected with the uniform portion, the tapered portion being extended from a junction in a manner that a thickness of the tapered portion gradually decreases from the fixed thickness of the uniform portion to a predetermined thickness, wherein the uniform portion and the tapered portion being integrally connected at the junction; and
a damping layer attached to the tapered portion of the vibration-reduced body
wherein the apparatus further comprises a connector attached to a bottom of the uniform portion of the vibration-reduced body, so as to connect the vibration-reduced body to a device to be vibration-reduced.
