<p>A speaker device having a voice coil (30) formed flat and driven in the direction of the flat surface, wherein the voice coil is driven by sufficient electromagnetic force. A speaker device is provided with a vibration plate (10), a stationary section (100) for supporting the vibration plate so that the vibration plate can vibrate in a vibration direction, and a drive section (14) provided to the stationary section and applying vibration to the vibration plate by means of an audio signal. The drive section is provided with a voice coil (30) vibrated in a direction different from the direction of vibration of the vibration plate by an audio signal inputted in the voice coil, a magnetic circuit (20) for forming magnetic paths (M) passing through the voice coil, and a rigid, vibration direction changing section (50) for transmitting vibration of the voice coil to the vibration plate after changing the direction of the vibration. The magnetic circuit has the magnetic paths, the voice coil is formed flat and is provided with electrically conductive members (31a, 31b) continuous from one end to the other end thereof, and some of the electrically conductive members are mounted in the magnetic paths so as to be arranged side by side in the same direction.</p> |
