DYNAMIC LOUDSPEAKER

PURPOSE:To prevent a resonance by a specified frequency, and to improve a sound pressure frequency characteristics in the whole band in an audible range by making a molded resin body adhere to an edge part, varying a compliance of the edge part, and dispersing a resonance frequency. CONSTITUTION:A dome part 1a and an edge part 1b connected to said part are formed in one body to a uniform thickness by a resin material, on a diaphragm 1. Also, a molded resin body 7 is made to adhere extending from the center part of the surface of the edge part 1b to the outside circumferential part of the surface. In case of a frequency of a resonance frequency or below of the edge part 1b, it moves as one body with the dome part 1a, therefore, no disorder is generated in a sound pressure frequency characteristics. Also, in a resonance frequency point of the edge part 1b, since the molded resin body 7 is made to adhere to the edge part 1b, a compliance of the edge part 1b becomes ununiform, and no resonance occurs. Also, in the adhering part and the non-adhering part, the resonance is different, therefore, the resonance is dispersed.
