  • Patent number: 11381894
    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.
