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.

An X-ray protection device adapted to be incorporated into a monitor that includes a cathode ray tube actuated by a high voltage from a transformer powered by a low voltage power supply. The X-ray protection device includes a circuit which is coupled to a low voltage output of the transformer to obtain a signal from the transformer to represent the high voltage applied by the transformer to the cathode ray tube. The signal is then voltage divided and analog-to-digital-converted to supply a digital signal to a microprocessor which receives and processes the digital signal to give a comparison result by comparing the digital signal with predetermined upper and lower bounds and a triggering threshold and a switching circuit which is connected to the microprocessor to be actuated by the microprocessor in response to the comparison result to cut off the power supplied to the transformer in order to shut down the monitor if the digital signal is not between the upper and lower bounds or is greater than the threshold for a time period greater than a predetermined time interval.
