Abstract: A loudspeaker includes: a frame; a yoke fixed to the frame; a magnet fixed to the yoke; a plate fixed to an upper surface of the magnet which is opposite to a surface of the magnet which is fixed to the yoke; a vibratable voice coil arranged in a first magnetic gap formed between the yoke and the plate; a diaphragm having an outer-edge portion joined to the voice coil; and a support member supporting the diaphragm in a vibratable manner, and composed of edges, one end of each edge being fixed to the frame. The plate is composed of: a flat-plate part fixed to the upper surface of the magnet, and having, at an upper surface thereof, a planar portion extending from the outer-edge portion up to a predetermined distance; and a protruding part disposed on the flat-plate part excluding the planar portion, and protruding toward the diaphragm.

Abstract: A sound presentation device including: a casing; an electroacoustic transducer that is installed in such a way that a space inside the casing is divided into a first empty chamber and second empty chamber that are acoustically isolated, and that receives an electrical signal and vibrates; and a vibration plate that makes contact with a body surface of a human body when the sound presentation device is mounted on the body surface, and causes vibration of the electroacoustic transducer to be propagated to the human body via the first empty chamber, the second empty chamber suppressing sound waves produced by the vibration of the electroacoustic transducer from being emitted to outside of the sound presentation device via the second empty chamber.
