Abstract: A device with water drainage for a speaker using a three-dimensional canopy shaped retainer and hydrophobic mesh is provided. The device includes a three-dimensional (3D) retainer having a canopy shape with an outer side and an inner side, the outer side having a generally convex shape and the inner side having a generally concave shape, the 3D retainer comprising apertures therethrough. The device further includes a hydrophobic mesh located at least at the apertures at the outer side of the 3D retainer, the hydrophobic mesh being air-permeable.

Abstract: A device with linear slots for water drainage is provided. The device comprises: a bezel covering a cavity and a microphone/speaker mounted therein, the bezel having outer and inner faces, the inner face facing the cavity; linear slots through the bezel between the faces, the linear slots being obliquely angled relative to an upright axis of the bezel; linear slats separating the linear slots at the bezel and forming sides thereof having dimensions selected to promote formation of water droplets thereon of a size which overcome water surface tension and flow out of the linear slots when the bezel is exposed to one or more of mist, rain, water and humidity; and one or more recesses at the inner face, adjacent to the linear slots, the one or more recesses to collect water from the water droplets as the water flows out of the linear slots.
