Abstract: Disclosed is a device for removing moisture from within an enclosure associated with a heat source. The device comprises a desiccant material in a chamber and a first port between the chamber and an outside environment outside. The device includes a second port between the chamber and the enclosure, having a first barrier extending across the second port and comprising an air-impermeable water vapour-permeable moisture transport layer and a second barrier extending across the second port. In use, water vapour within the enclosure permeates through the moisture transport layer and into the chamber, where it is adsorbed by the desiccant material. The desiccant material can be regenerated by heating the device, using the associated heat source. Pressure within the chamber promotes flow of vapour through the first port. Heat is conducted to the first barrier via the second barrier to prevent or reduce condensation.

Abstract: Various aspects of the present disclosure are directed toward apparatuses, systems and methods that include an acoustic apparatus. The apparatuses, systems and methods may include an acoustic membrane and a protective housing defining an interior space in which the acoustic membrane is received.
