Abstract
A speaker includes a frame, a partition wall and a pitch-adjustment ring. The partition wall is coupled with the frame to isolate a high-pitched sound zone from a low-pitched sound zone. A pitch-adjustment ring is rotatably coupled to the frame and has at least one permeable section and at least one non-permeable section. The pitch-adjustment ring is rotatable to align the at least one permeable section with the high-pitched sound zone or the low-pitched sound zone.
