Vibrating debris remover

A device for removing debris from a material, the material having a plurality of resonant frequencies, including a fundamental resonant frequency and multiples of the fundamental resonant frequency the fundamental resonant frequency being determined by dividing the velocity of sound through the material by two times the length of the material, the device comprising:

• a converter unit that produces mechanical motion at an output;
• and,
• a coupler unit attached to both the converter unit output and the material, the coupler unit having a resonant frequency and being operable for transmitting the mechanical motion produced by the converter unit into the material;
• wherein,
• one of the resonant frequencies of the material is substantially equal to the resonant frequency of the coupler.

A device for removing debris from a material, comprising:

• a converter unit that produces mechanical motion at an output;
• a coupler having a first end and a second end, the first end being operably associated with the converter output so as to transmit the mechanical motion produced by the converter unit, the second end being attached to the material;
• wherein,
• the converter unit, coupler, and material each have an impedance, the impedance of the coupler being substantially equal to the impedance of the material.
