a) a housing;
b) a speaker mounted in the housing that outputs an amplified audio signal;
c) a tune pipe cavity at least partially formed in the housing;
d) a microphone mounted in the tune pipe cavity, wherein the tune pipe cavity is configured to have a length, diameter, and volume that creates an acoustic filter for incoming sound to the microphone that filters out some frequencies not associated with human speech; and
e) circuitry receiving a microphone signal from the microphone and submits the microphone signal to a voice recognition system.
