ABSTRACT:
Sound radiating structure includes a plurality of pipes each defining an inner cavity along the length of the pipe. Each of the pipes has an end opening at one end and is closed at the other end with a closure. Each of the pipes also has a side opening in its one side portion. When a sound is input to the sound radiating structure, it re-radiates various sound waves through a number of the end and side openings together with reflected sound waves.
