Abstract: An electro-acoustic transducer is provided that comprises a diaphragm and a magnet assembly comprising a magnet and a back plate. The back plate comprises at least one first vent. The diaphragm generates sound during a movement of the diaphragm relative to the back plate. The transducer further comprises a printed circuit board comprising at least one second vent and a cavity between the printed circuit board and the back plate that separates the at least one first vent from the at least one second vent.

Abstract: An in-ear headphone comprises an earbud body constructed and arranged for positioning in an ear canal of a wearer, and configured to have a distal end farther into the ear canal than a proximal end. The earbud body includes a cavity and an opening to the cavity. The in-ear headphone further comprises a transducer in the opening to the cavity, a portion of the transducer facing outward from the opening; a microphone at the distal end of the earbud body; an earbud tip on the earbud body and complying with a surface of the earbud body; and an acoustically resistive mesh structure at a distal end of the earbud tip. The mesh structure covers the microphone and the portion of the transducer facing outward from the opening.

Abstract: A headphone includes an earphone that includes an earcup, an ear cushion, and a driver plate assembly. The driver plate assembly is supported in the earcup and includes a driver plate, a driver mounted along a rear surface of the driver plate, an opening that is provided in the driver plate to allow acoustic energy to pass from the driver into a user's ear canal, a ring that is arranged substantially coaxially with the opening, and an acoustic mesh. The ring defines a planar surface on which the acoustic mesh is mounted.

Abstract: An active noise reduction earbud includes a housing and a first feedforward microphone disposed in the housing. A first sound inlet opening extends through the housing and is configured to conduct external sound to the first feedforward microphone. The first sound inlet opening is configured to sit within a concha cavum of a user's ear and faces toward an auricle of the user's ear when the earbud is worn.

Abstract: Various aspects include a wearable audio device having active noise reduction (ANR), where the ANR device includes: a feedback microphone; an electroacoustic transducer; and a feedback compensator configured to output a noise reduction signal to the electroacoustic transducer in response to a feedback signal from the feedback microphone, wherein the feedback compensator includes a tunable filter that modulates a loop gain in response to an adverse low frequency event being detected in the noise reduction signal outputted from the tunable filter, wherein the tunable filter is configured to maintain a substantially similar loop gain shape near a low frequency cross-over as the low frequency cross-over changes during loop gain modulation.
