Abstract: A speaker device has a magnet, outer yokes, and inner yokes which are assembled so that a magnetic gap is formed between the outer yoke and inner yokes over which a magnetic flux which is generated from the magnet cuts across. A voice coil unit which is linked to a diaphragm is disposed within the magnetic gap, and positioning members determine the positions of the inner yokes and the outer yokes which attach magnetically to the magnet such that a magnetic gap is formed. The speaker device has a magnetic circuit of which the construction facilitates assembly, and recycling of various individual parts is relatively easy.

Abstract: A speaker device includes a voice coil unit and a diaphragm linked to the voice coil unit. A first supporting unit and a second supporting unit elastically support the end portions of the voice coil unit so that the voice coil portion of the voice coil unit can vibrate within the magnetic gap in the direction of the face thereof. Each of the first supporting unit and the second supporting unit has a configuration that is in a shape bent so as to extend up and bend down from an end that is fixed to a fixing position. Thus, a speaker device in which the voice coil unit can vibrate with a greater amplitude is provided.

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.
