    Abstract: A thin speaker capable of developing a high sound pressure level in a high sound pressure area and securing a high sound pressure area regeneration band, comprising a diaphragm having first and second portions corresponding to the inside and outside of a voice coil. One portion is formed in an elliptic arc shape in cross section in a plane including the center axis of the voice coil, and the other portion may include a third portion in which a cross section in the plane including the center axis is formed of a first arc and a fourth portion in which a cross section in the plane including the center axis is formed of a second arc with a radius larger than that of the first arc, adjacent to the third portion, and apart from the voice coil more than the third portion.
