A composite speaker is disclosed that can more easily be made thin and small, and is configured so that the assembly process of the speaker is easy. A first space that opens to the rear is formed in a main yoke that forms a magnetic field emitter, and a magnetic gap is formed in the first space. A first voice coil, connected to an inner peripheral end of a first diaphragm whose surface area is large, is inserted into the first magnetic gap toward the front direction. A second space that passes through from front to back is provided in the main yoke, a second magnetic field emitter is mounted therein, and a second diaphragm whose surface area is small is provided in front thereof. Because of the structure in which the second magnetic field emitter is housed within the first magnetic field emitter, the front-to-back dimension of the speaker can be reduced.
