<p><P>PROBLEM TO BE SOLVED: To provide a compact and thin electronic device which is deformed into a plurality of states, and reliably detecting magnetism without being influenced by a magnet of a speaker when a state of the electronic device is determined by the magnet and Hall ICs. <P>SOLUTION: The electronic device is provided with a first casing 10 and a second casing 11. The speaker and the magnet 17 are stored in the first casing 10 to have the same polarity. A pair of Hall ICs 18 for detecting magnetism to determine the polarities are stored in the second casing 11. The speaker and the magnet 17 stored in the first casing 10 and the pair of Hall ICs 18 stored in the second casing 11 are mutually overlapped in a first state, while in a second state, the speaker and the magnet 17 stored in the first casing 10 and the pair of Hall ICs 18 stored in the second casing 11 are mutually overlapped. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
