Abstract
A good output state of sound is ensured without a cost increase. A speaker unit includes: a vibration plate; a magnetic circuit; a bobbin to which an inner peripheral portion of the vibration plate is attached and which is varied in an axial direction by the magnetic circuit; and a cap attached to the vibration plate and located to face the bobbin in the axial direction of the bobbin, in which a center axis of the bobbin is arranged in a state of being inclined with respect to a horizontal plane or a vertical plane, and the cap is formed in a shape eccentric to the center axis of the bobbin. Thus, since the cap is eccentric to the center axis in a state in which the center axis of the bobbin is inclined with respect to the horizontal plane or the vertical plane, it is possible to freely control a pointing direction in an inclined direction, good directivity characteristics can be obtained, and a good output state of sound can be ensured without a cost increase.
