Abstract
A loudspeaker including a magnetic circuit; a voice coil body; a diaphragm attached to the voice coil body; a housing which accommodates the magnetic circuit and the voice coil body and to which an outer circumferential portion of the diaphragm and the magnetic circuit are attached; two connection terminals disposed exposed inside and outside the housing; and signal wires which extend from the voice coil body and are connected to the connection terminals. Each signal wire is outwardly curved to be away from a virtual straight line connecting the proximal end of the signal wire and the connection portion. The distal end of the signal wire projects from the connection portion toward the voice coil body.
