<p><P>PROBLEM TO BE SOLVED: To provide a sound-deadening structure capable of effectively reducing the entire sound transmitted inside an air path, to further provide an apparatus with the sound-deadening structure, and also to provide a sound-deadening structure which has a long service life and can maintain a sound-deadening effect over a long period of time. <P>SOLUTION: The sound-deadening structure 50 is disposed inside the air path 10, disposed at a position corresponding to an "antinode" part of a sound pressure mode by air column resonance of at least the air path 10, and is constituted by cylindrically molding a resin material. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
