A yoke of a communication buzzer, and an apparatus and a method for manufacturing the yoke are provided to prevent the yoke from being separated from a buzzer base while the buzzer is assembled by inserting a part of a yoke base into a casing of the buzzer by an injection mold for molding the casing thereof. A yoke(13) is comprised of a base(11) and a stick(12), and installed in a communication buzzer. A recessed groove(15) is formed on at least one side of the base. The recessed groove supports the base by an injection mold for molding a casing of the buzzer. A pressing groove(16) is formed on an upper surface of the base contacted to the recessed groove. The pressing groove inserts a part of the base into the casing of the buzzer by an injection mold for molding the casing thereof and thereby prevents the yoke from being separated from the base of the buzzer.
