PROBLEM TO BE SOLVED: To provide a speaker apparatus with an excellent reproducing characteristic without being affected by interference in a high sound frequency band. SOLUTION: The speaker apparatus includes: a diaphragm 5 supported vibratably in a prescribed direction z; a pair of magnets 11a, 11b arranged opposite to a direction x orthogonal to the vibration direction z of the diaphragm 5; and a voice coil 6 wound in a winding axis direction in parallel with the direction x to which a pair of the magnets 11a, 11b oppose. A part 6a of the voice coil 6, where a current flows in a direction orthogonal to the winding axis direction and the vibration direction, is joined with the diaphragm 5, and a part 6b of the voice coil 6, where the current flows in the other direction, is arranged opposite to a pair of the magnets 11a, 11b.
