Claim 13:
14. A device comprising:
a first waveguide having a first opening at a first end and a second end, the first waveguide to receive first acoustic energy at the first opening and to propagate the first acoustic energy to the second end, the second end of the first waveguide opposite the first end of the first waveguide, wherein the first waveguide has a substantially conical shape with a first larger section physically proximal to the first opening and a first smaller section physically proximal to the second end and an angle between the first top opening and a surface of a wall of the first waveguide is between approximately 21.10 degrees and approximately 41.5 degrees; and
a second waveguide having a first opening at a first end and a second end, the second waveguide to receive second acoustic energy and third acoustic energy at the first opening and to propagate the second acoustic energy and the third acoustic energy to the second end, the second end of the second waveguide opposite the first end of the second waveguide, wherein the second waveguide has a substantially conical shape with a first larger section physically proximal to the first opening and a first smaller section physically proximal to the second end and an angle between the second top opening and a surface of the wall of the second waveguide is between approximately 94.2 degrees and approximately 39.10 degrees.
