<p>Provided is a thin speaker device capable of high-quality and high-volume bass reproduction by means of a large-area diaphragm. The speaker device is provided with a diaphragm (10) having a substantially V-shaped cross-section, a stationary section (100) for vibratably supporting the outer periphery of the diaphragm (10) along the vibration direction thereof, and plural driving units (14) for supporting an inclined plane of the diaphragm (10) and imparting vibration to the diaphragm in response to an audio signal. The driving unit (14) is provided with a magnetic circuit (20) in which a magnetic gap (20G) is formed along a direction different from the vibration direction of the diaphragm (10), a voice coil (30) vibratably supported along a uniaxial direction in the magnetic gap (20G), and a rigid vibration direction change section (50) for changing the direction of the vibration of the voice coil (30) and transmitting the vibration changed in direction to the diaphragm (10).</p> |
