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.
