  • 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.

  • Patent number: 10825622
    Abstract: A remote speaker microphone includes a housing having a bezel defining an outer surface. The remote speaker microphone further includes a toggle switch lever that rocks back and forth relative to the bezel. The remote speaker microphone further includes a bezel opening through which the toggle switch lever extends at the outer surface. The bezel and the toggle switch lever define a predetermined gap within the bezel opening and within which the toggle switch lever rocks. The bezel, the bezel opening, and the toggle switch lever together form an ice crushing region in response to rocking the toggle switch lever.

  • Patent number: 10779067
    Abstract: A grille configured for shielding a microphone cavity. The grille includes a first side. The first side includes a first plurality of parallel slats defining a first plurality of channels extending along a first direction. The grille includes a second side opposite the first side. The second side includes a second plurality of parallel slats defining a second plurality of channels extending along a second direction at a first angle relative to the first direction. The first plurality of parallel slats and the second plurality of parallel slats define a lattice having a plurality of openings extending through the grille. The openings are configured to diffuse air moving across the lattice. The channels and slats are configured to induce capillary action on water coming in contact with the lattice to drain water from the openings and the microphone cavity.
