Abstract
The present invention discloses a vibration membrane assembly for a speaker, a method for producing a vibration membrane assembly and a speaker. The assembly comprises a vibration membrane and a vibration membrane carrier ring. The method comprises providing a first thermal molding die having a molding side, the molding side having a profile which is complementary to that of the second side of the vibration membrane assembly, putting the vibration membrane carrier ring onto the molding side of the first thermal molding die and laying a vibration membrane blank onto the vibration membrane carrier ring to bring the vibration membrane blank in contact with the vibration membrane carrier ring, applying a pressure to the vibration membrane blank against the vibration membrane carrier ring to nest and fix the vibration membrane blank on the vibration membrane carrier ring to form the vibration membrane assembly, removing the pressure off the vibration membrane blank and separating the vibration membrane assembly from the first thermal molding die.
