Abstract: A low profile audio speaker having a power less than 5W includes a concave chassis; a magnet secured onto a bottom of the chassis; a top plate mounted on the magnet; a mounting flange secured to a peripheral edge of the chassis; an outer peripheral corrugation having an outer edge secured to the mounting flange; a central diaphragm secured to the peripheral corrugation; and a voice coil extending downward from the diaphragm toward the chassis with the magnet and the top plate being surrounded. The peripheral corrugation is formed of PEI, PEN, PET, foam, or fabric. The peripheral corrugation is shaped as a circle or an oval. The peripheral corrugation includes at least two grooves and alternate ridges with the outermost ridge being flattened to be secured onto the top of the mounting flange. The diaphragm is formed of PEI, PEN, PET, foam, or fabric.

Abstract: A loudspeaker with high power efficiency and low resonance frequency is achieved by having a damper directly or indirectly sleeving beside a coil on a voice coil so that gravity center of loudspeaker is low and stable and the voice coil does not dislocate easily to keep acoustic performance of the loudspeaker excellent without acoustic distortion and to shorten the length of the voice coil. Moreover, a U-yoke attaches a frame in form of an insertion combination to shorten the loudspeaker at joints. Thereby, the depth of the loudspeaker is significantly reduced in size.
