Speaker and method of producing the same

A speaker comprising:

• an edge having an outer circumference attached on an edge mounting portion of a resin frame by a resin ring provided on a front surface of the outer circumference,
• the resin ring including, on a back surface thereof, an energy director having a tip portion abutting on a front surface of the edge mounting portion and being meltable from the tip portion by ultrasonic waves.

A method of manufacturing a speaker, the method including placing an outer circumference of an edge between a resin frame and a resin ring, where the resin ring is on a front side with respect to the resin frame, and attaching the outer circumference of the edge by ultrasonic waves, the method comprising,

• providing an energy director on an outer circumference of an edge mounting portion of the resin frame or an outer circumference of the resin ring, the energy director being configured to melt from a tip portion thereof upon receipt of energy of the ultrasonic waves on an outer circumference of an edge mounting portion of the resin frame or an outer circumference of the resin ring;
• and
• welding the resin frame and the resin ring via the energy director melted, so that the outer circumference of the edge are fixedly sandwiched between the resin frame and the resin ring.
