Abstract: Various implementations include audio devices configured to mitigate electrostatic discharge (ESD) events, or strikes. In certain implementations, an audio device includes: a device housing containing: a microphone housing having a microphone therein; a stiffener over the microphone housing; and a mesh overlying the stiffener, wherein the mesh is positioned to divert an electrostatic discharge (ESD) strike away from the microphone in the microphone housing.

Abstract: Various implementations include audio devices configured to mitigate electrostatic discharge (ESD) events, or strikes. In certain implementations, an audio device includes: a microphone mounted on a first side of a printed wiring board (PWB); and an electrostatic discharge (ESD) protection element coupled to a second side of the PWB directly opposite the microphone, wherein the ESD protection element is positioned to divert an ESD strike away from the microphone.

Abstract: A port tube for an earphone, wherein the port tube is configured to acoustically couple a rear acoustic cavity of the earphone to an external environment, includes a first section that is proximate the rear cavity and defines a first cross-sectional area, a second, transitional, section that is coupled to the first section and defines a gradually increasing cross-sectional area, a third, curved and banked, section that is coupled to the second section and defines a second cross-sectional area that is greater than the first cross-sectional area, a fourth, transitional, section that is coupled to the third section and defines a gradually decreasing cross-sectional area, and a fifth section that is coupled to the fourth section and defines a third cross-sectional area that it less than the second cross-sectional area.
