<P>PROBLEM TO BE SOLVED: To provide a loudspeaker magnet structure that can provide reduced fringe magnetic fields and improved voice coil motor force constant (BL) characteristics. <P>SOLUTION: The magnet structure of a loudspeaker comprises: a core including a first core surface and a second core surface; a first magnet coupled to the first core surface; a second magnet coupled to the second core surface. The first magnet and the second magnet are positioned so that a polarity of the first magnet is aligned in a same direction as a polarity of the second magnet. The core has a height greater than a combined height of the first magnet and the second magnet; a magnet housing coupled to the first magnet; and a core cap coupled to the second magnet. The magnet housing and the core cap are configured to form a voice coil gap. <P>COPYRIGHT: (C)2012,JPO&INPIT |
