Abstract: A speaker includes a frame, a magnetic circuit system, a balance element, and a diaphragm. The frame has a perforation, a bearing surface, and an accommodating space surrounding the perforation. The magnetic circuit system is disposed in the accommodating space and includes a voice coil and a magnet, and the voice coil is located between the bearing surface and the magnet. The diaphragm has a hole corresponding to the perforation, and the diaphragm is connected to the frame and the voice coil. The balance element is disposed in the accommodating space and surrounds the perforation, and the balance element is connected to the voice coil and the bearing surface.

Abstract: A moving-coil speaker includes a frame, magnetic circuit system setting section, and magnetic circuit system. The frame has a first surface. The magnetic circuit system setting section is formed on the first surface and includes a first region and a second region surrounding the first region. The magnetic circuit system is disposed at the magnetic circuit system setting section and includes at least one voice coil which spaced from the first surface of the frame and having a first end and a second end opposite to the first end. The first end defines a virtual plane extending along a radial direction of the voice coil. The virtual plane and the first surface of the first region define a first distance. The virtual plane and the first surface of the second region define a second distance. The second distance is greater than the first distance, and the second distance and the first distance are parallel.

Abstract: A diaphragm structure including a suspension side edge and a central part is provided. The suspension side edge is connected to a periphery of the central part and surrounds the central part. The central part includes a main body part and a structural strengthening part, and the structural strengthening part is formed at a top end of the main body part.

Abstract: 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.

Abstract: 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.

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.

Abstract: 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.
