A speaker includes a frame and a partition wall coupled with the frame to form a boundary between an inner chamber and an outer chamber. The frame has an annular sidewall and a top wall. The annular sidewall has a plurality of through holes allowing the inner chamber and the outer chamber in fluid communication.

Speaker

A speaker includes a frame and a partition wall. The frame has ribs to define a central through hole and plural side through holes. The partition wall is coupled with the frame to form a boundary between a high-pitched sound zone and a low-pitched sound zone, wherein a total sum area of the side through holes covered by the partition wall is smaller than a total sum area of the side through holes uncovered by the partition wall.

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 includes a frame and a partition wall coupled with the frame to define a boundary between a high-pitched sound zone and a low-pitched sound zone. The high-pitched sound zone includes an electromagnetic component accommodating area and plural discontinuous sound chamber extension areas. The electromagnetic component accommodating area and the plural discontinuous sound chamber extension areas are fluid-communicable.

A magnetic circuit for coaxial speaker includes a first magnetic unit, at least one second magnetic unit arranged around the first magnetic unit and at least one third magnetic unit arranged around the at least one second magnetic unit. The magnetic pole arrangement of the second magnetic unit is reversed to the magnetic pole arrangement of the first magnetic unit and the third magnetic unit, enabling a first magnetic loop to be established between the first magnetic unit and the at least one second magnetic unit and a second magnetic loop to be established between the at least one second magnetic unit and the at least one third magnetic unit. The magnetic circuit is practical for use in the inner and outer drivers of a coaxial speaker, providing uniform magnetic field distribution, and facilitating speaker miniaturization.
