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.

A speaker comprising:
- a frame having a central through hole and side through holes around the central through hole;
- a partition wall coupled with the frame to form a boundary between a high-pitched sound zone and a low-pitched sound zone;
- a diaphragm coupled with the frame;
- a pitch-adjustment sheet disposed between the partition wall and the diaphragm, and rotatably coupled to the frame, the pitch-adjustment sheet has at least one permeable section and at least one non-permeable section, the pitch-adjustment sheet is rotatable to align the at least one permeable section with the high-pitched sound zone or the low-pitched sound zone;
- and
- a toggle structure coupled to the pitch-adjustment sheet, wherein the toggle structure is inserted through a corresponding one of the side through holes, and restricted by a boundary of the corresponding one of the side through holes.
