PROBLEM TO BE SOLVED: To solve the problem of the conventional manner in which a conduction failure occurs since a plate spring shape terminal is deformed so as to reduce contact pressure and to disable power feeding from a set side when a worker erroneously has contact with the plate spring shape terminal.SOLUTION: A speaker unit is configured by including: a plate spring shape terminal which is inserted to a frame in order to feed power from an external device to a voice coil and whose one end is joined with the voice coil; a stopper which is formed to be a nearly horizontal shape at the most distal end of the other end of the plate spring shape terminal in order to position an elastic deformation direction in the plate spring shape terminal; and wall shapes arranged in a direction intersecting with the elastic deformation direction of the plate spring shape terminal in a part of the frame. Thus, the plate spring shape terminal is prevented from being excessively deformed in the elastic deformation direction and also a worker is prevented from having contact with the plate spring shape terminal due to the wall shapes arranged in the frame. Consequently, the plate spring shape terminal is prevented from being deformed even in a direction intersecting with the elastic deformation direction.
