摘要:
The present invention relates to a loudspeaker (1). The loudspeaker (1) includes: a U-yoke for holding a magnet having a base (12) with an upstanding side (14) around the perimeter of the base (12); a frame (20) having a ring (22) around the U-yoke, the ring having a U-shaped cross-section orientated with a base (24) of the U abutting the side (12) of the U-yoke; a dome shaped diaphragm (40) connected to the frame (20) by a resilient member (30) around the dome (40), the resilient member (30) and the dome (40) being suspended from the frame (20); a first cavity (70) defined by the dome (40), resilient member (30), frame (20) and U-yoke; an external wall (80) around the circumference of the frame (20), the external wall (80) sealing a top of the U-shaped cross-section of the ring (22) forming a second cavity (100) between the external wall (80) and the ring (22); a port (110) in the frame (20) between the first cavity (70) and second cavity (100), wherein the first cavity (70) and second cavity (100) and the port (110) form a Helmholtz resonator system. The shape of the frame (20) in combination with the external wall (80) allows a Helmholtz resonator system to be established within the existing footprint of the loudspeaker.
