Patent ID: 6892856

Claim:
A sound radiating structure, comprising: a plurality of cavity-defining members, each of said cavity-defining members being of a hollow shape to define an inner cavity that extends in a particular direction, the inner cavity defined by each of said cavity-defining members having a length in the particular direction different from lengths of inner cavities defined by other said cavity-defining members, the inner cavities defined by said cavity-defining members being located adjacent to each other such that the cavity-defining members are disposed so as to adjoin each other perpendicularly to the particular direction in which the inner cavities defined thereby extend, each of said cavity-defining members includes an open end and a closed end such that the open end and the closed end of each of said adjacent cavity-defined members are staggered, and each of said cavity-defining members includes a side portion extending along the particular direction, and the side portion includes a side opening formed therein at a position of three-quarters of the length from the open end and communicating with the inner cavity defined by each of said cavity-defining members, wherein when a sound wave is input to said sound radiating structure, each of said cavity-defining members re-radiates the sound wave by resonance.
