Abstract:
A unitary printed circuit board assembly includes a circuit board and a flexible substrate extending from, and continuous with, the circuit board. The flexible substrate includes a first portion extending from the circuit board and terminating a second portion. The second portion of the flexible substrate can be wrapped about a spring form. The assembly can be disposed in a housing defining a body and an ear insertion stem, with the spring form disposed within the ear insertion stem with arms of the spring form applying a biasing force against inner surfaces of the ear insertion stem.
Abstract:
A device (400) includes a device hook receiver (503). The device hook receiver defines a port (707) to an acoustic chamber (1103) disposed within the device. An ear hook (403) includes a device hook (502). The device hook attaches to the device hook receiver and at least partially visibly obscures the port. The device hook also provides separation between an outer surface (1303) of the device hook and the port.
Abstract:
An ear hook assembly (401) is provided. The ear hook assembly (401) includes a device hook engagement component (405), an ear hook engagement component (406), and a retention sleeve (404). The retention sleeve can include comprising at least one protuberance (1207) extending into the retention sleeve toward an engagement axis (408) of the assembly. One of the device hook engagement component or the ear hook engagement component can include at least two retention sleeve friction engagement components (409,410) radially separated by a cantilevered protuberance engagement component (901) about the engagement axis. The cantilevered protuberance engagement component can include a distal end (1002) biased against the protuberance to retain the device hook engagement component and the ear hook engagement component together.
Abstract:
The present arrangements relate to a microphone boom assembly. A first microphone can be positioned proximate to a first aperture defined in a first side of the microphone boom through which acoustic signals propagate to the first microphone, and a second microphone can be positioned proximate to a second aperture defined in a second side of the microphone through which the acoustic signals propagate to the second microphone. The first microphone can be connected to a first side of a flexible printed circuit at a first location and the second microphone connected to a second side of the flexible printed circuit at a second location, the flexible printed circuit mounted into the microphone boom with a bend in the flexible printed circuit positioned between the first location and the second location.
