Abstract (en)
An air induction system comprises an air induction body (10), a speaker (14) with a first diaphragm (18) disposed about the air induction body, and a second diaphragm (22) spaced from the first diaphragm. A signal is generated from the first diaphragm and transmitted to the second diaphragm. The second diaphragm generates a noise attenuating sound. <IMAGE>
