Loudspeaker, and module and electronic apparatus using the loudspeaker

Shigeru Tomoeda; Takanori Fukuyama; Masahide Sumiyama

A loudspeaker is provided that satisfies requirements for both a small size and a high sound pressure. In addition, the heat capacity of the magnetic circuit and the heat dissipation of the voice coil are improved in this loudspeaker. Using at least two pieces of bar magnets ( 21 ), an outer magnet type magnetic circuit is structured in which the magnetic gap comprising an upper plate ( 22 ) and a lower plate ( 23 ) has a straight section. Also, the configuration of the voice coil ( 28 ) is that of a track.
