An electronic device includes a first device housing and a second device housing. A hinge couples the first device housing to the second device housing. The first device housing is pivotable about the hinge relative to the second device housing. The hinge separates a first chamber defined by the first device housing and a second chamber defined by the second device housing. A flexible substrate passes through the first chamber and the second chamber. The flexible substrate spans the hinge, either by passing through or around a hinge housing. The flexible substrate deforms to a curvilinear deformed state within one or both of the first chamber or the second chamber when the first device housing and the second device housing pivot about the hinge from a closed position to an axially displaced open position.

Hinged electronic device with chambers accommodating a dynamic flexible substrate and corresponding systems

An electronic device as provided here includes a primary housing, an acoustic transducer, a lower layer of acoustic mesh material, and an upper layer of acoustic mesh material. An interior volume is defined within the primary housing. The primary housing includes an interior mounting surface, an exterior mounting surface, and an acoustic port. The transducer is located within the interior volume, and the lower layer of mesh material is coupled between the interior mounting surface and the transducer to cover a lower opening of the acoustic port. The upper layer of mesh material covers an upper opening of the acoustic port. Each layer of mesh material provides an amount of acoustic transparency and an amount of visual obscurity such that the transducer is effectively hidden from view without adversely impacting the audio performance characteristics of the transducer.

Electronic device with an improved acoustic mesh system

Disclosed are hinges with a single interface or single seam between two halves of the hinge, configured to route through the hinge a flexible circuit element to couple electronic circuitry in a first housing with electronic circuitry in a second housing. An axial shaft with an elongated slot is received by the two halves of the hinge. The shaft extends at least across a portion of the width of the first housing. To route the flexible circuit element, the elongated slot is configured to hold fixed the midsection of the flex cable, relative to the shaft during rotation of the shaft. The shaft has an outer circumference, and at least a portion of the shaft defines a shallow groove at the outer circumference. A portion of the flexible circuit element is wrapped around the shaft forming a radial service loop at the shallow groove to accommodate rotation of the shaft.

Electronic device having a single seam hinge

This invention is a wireless communication device () including a first housing () with a housing support (), a second housing () positioned about the housing support, or a portion thereof, so that the second housing may rotate around the housing support, and an interchangeable bezel () having input keys () and output functionality effectuated by light emitting diodes ().
