摘要： A speaker comprising a magnetic circuit containing at least a magnetic gap, a frame connected to the magnetic circuit, and an integral unit consisting of a ring shaped voice coil bobbin unit which is wound around with coil to be coupled in the magnetic gap, and a diaphragm unit formed in the shape of an inverse letter “U” disposed on an upper edge of the voice coil bobbin unit. This speaker provides enhanced rigidity, a reduction in production/assembly cost, and an improved sound pressure level.
