Abstract
A material sprayer includes a hopper and a shaker assembly mounted onto a sidewall of the hopper. The hopper includes at least one sidewall that extends along a first plane. The shaker assembly includes a resilient bracket, an electromagnetic coil, and an armature. The resilient bracket is mounted to the sidewall of the hopper and includes first and second ends and a curved portion. The electromagnetic coil is mounted to a portion of the resilient bracket and is configured to generate a magnetic field in response to a current from a power source. The armature is mounted to a portion of the resilient bracket such that the armature is able to move relative to the electromagnetic coil along an acceleration axis that is orthogonal to the first plane of the sidewall of the hopper.
