摘要： A headset cup having a front cavity and a rear cavity separated by a driver, with a mass port tube connected to the rear port to present a reactive acoustic impedance to the rear cavity, in parallel with a resistive port, the total acoustic response of the rear cavity remaining linear at high power levels. In some embodiments, the mass port tube is made of metal, while the headset cup is otherwise made of plastic.

摘要： A wall separates a first volume from a second volume and has a hole allowing passage between the first volume and the second volume. A wire passes through the hole, and a gasket surrounds the wire at the hole. The gasket includes a first section including a groove between a first flange and a second flange, the groove has an outer diameter matched to the diameter of the hole and the flanges have outer diameters greater than the diameter of the hole. A second section adjacent the first flange includes a tubular portion having a diameter less than the diameter of the hole and a tapered section smoothly transitioning from the diameter of the tubular portion to the diameter of the first flange. The gasket prevents flow of fluid through the hole between the first volume and the second volume.
