A light weight and low profile speaker apparatus is provided. In one embodiment, the speaker apparatus includes: a frame member; a magnetic circuit; a supporting member disposed on a bottom portion of the frame member for securing and supporting the magnetic circuit at an opposite circumferential end portion of a circumferential wall portion of a first yoke relative to a plate portion; a voice coil unit disposed inside a magnetic gap in the magnetic circuit; a coupling member disposed outward of the circumferential wall portion of the first yoke; and a diaphragm having an inner circumferential end portion coupled to the coupling member. The voice coil unit and the coupling member are joined by a joint member that extends in a direction transverse to the circumferential wall portion of the first yoke; and a space where the joint member joining the voice coil unit and the coupling member can move is formed in each of the circumferential wall portion of the first yoke and the supporting member. |
