Patent attributes
A speaker apparatus includes at least one of an inner flux applicator and an outer flux applicator includes an annular first member and an annular second member. The first member having a first surface that faces toward the magnetic gap, the first member satisfying L1>W1 where L1 is a length of the first surface in a direction parallel to the central axis and W1 is a width of the first member in a direction orthogonal to a central axis. The second member is magnetically coupled with the first member and arranged on an outer side of the first member, the second member satisfying W2>L2 where W2 is a width of the second member in a direction orthogonal to a central axis and L2 is a length of the second surface in a direction parallel to the central axis, and L1>L2.
