出力を機械的振動に変え、車内側ウエザーストリ
ツプに伝える拡声器からなる騒音減衰機構を備え
たウエザーストリツプ。 A sound collector that collects the sound generated on the weather strip on the outside of the vehicle, converts it into an electrical signal, and amplifies the output of the sound collector, either on the door alone or in multiple stages stacked on the door and body. It is equipped with a noise damping mechanism consisting of an amplifier that converts the output of the amplifier, a phase converter that converts the phase of the output of the amplifier to an opposite phase, and a loudspeaker that converts the output of the phase converter into mechanical vibration and transmits it to the weather strip inside the car. weather strip.
