ABSTRACT:
A loudspeaker is provided, which has a configuration in which suspension holder extending in a cylindrical shape widening downward is provided on the rear surface of diaphragm so as to be integrated with diaphragm, and the periphery of suspension holder is coupled to frame via second edge. With such a configuration, adhesion work between the suspension holder and the diaphragm as well as heating and drying work of adhesive are not required, thus enabling the productivity to be considerably improved and production equipment and space to be reduced.
