Patent number: 10825622Abstract: 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.Type: GrantFiled: March 22, 2019Date of Patent: November 3, 2020Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Zhen Xiang Oh, Mohd Hizami Abdul Hamid, Kuang Eng Lim, Wei Hung Tai

Patent number: 10779067Abstract: 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.Type: GrantFiled: December 20, 2018Date of Patent: September 15, 2020Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Charles B. Harmke, Oleg G. Harizanov, Geng Xiang Lee, Kuang Eng Lim, Michael Page, William Robertson
