Publication number: 20220192335Abstract: A case for a portable electronic device includes a housing, a lid, and a hinge rotatably coupling the lid to the housing such that the lid is operable between an open position and a closed position. The hinge includes a first multipole magnet coupled to the lid such that the first multipole magnet rotates with the lid. A second multipole magnet is coupled to the housing and is arranged coaxially with the first multipole magnet and such that the first multipole magnet and the lid rotate relative to the second multipole magnet. The lid is unstable between the open and closed positions, such that, between the open position and the closed position, the lid is biased toward either the open position or the closed position depending on an angle of orientation of the lid relative to the housing.Type: ApplicationFiled: December 20, 2021Publication date: June 23, 2022Applicant: Bose CorporationInventor: Stephen J.
