摘要： A wearable audio device is provided. The wearable audio device may include a first array of microphones linearly arranged on the wearable audio device at a positive angle relative to a horizontal axis of the wearable audio device. The microphones of the first array may be configured to capture far-field audio. The wearable audio device may include a second array of microphones linearly arranged on the wearable audio device at a negative angle relative to the horizontal axis. The microphones of the second array may be configured to capture near-field audio. The wearable audio device may include circuitry arranged to (1) generate a user voice audio signal based on the captured near-field audio, (2) generate a desired audio signal based on the captured far-field audio, and (3) generate a differentiated signal based on the desired audio signal and the user voice audio signal.

摘要： An active noise reduction earbud and method. The earbud includes a housing comprising an outlet portion that defines a sound outlet, wherein the outlet portion is configured to be located in or proximate the external auditory meatus of a user's ear, a first feedforward microphone configured to develop a first input signal, and a first sound inlet opening in the housing and configured to conduct external sound to be sensed by the first feedforward microphone, wherein the first sound inlet opening is proximate the outlet portion.

摘要： A system and method for externalizing sound. The system includes a headphone assembly and a localizer configured to collect information related to a location of the user and of an acoustically reflective surface in the environment. A controller is configured to determine a location of at least one virtual sound source, and generate head related transfer functions that simulate characteristics of sound from the virtual sound source directly to the user and to the user via a reflection by the reflective surface. A signal processing assembly is configured to create one or more output signals by filtering the sound signal respectively with the HRTFs. Each speaker of the headphone assembly is configured to produce sound in accordance with the output signal.

摘要： A wearable audio device including first and second transducer modules is provided. The first transducer module may include a first transducer. The first transducer module may further include a first enclosure having a top side defining a first slit and a bottom side defining a second slit. The first enclosure may be configured to guide a first sound pressure through the first slit, and a second sound pressure through the second slit. The second transducer module may include a second transducer. The second transducer module may include a second enclosure having a top side defining a third slit and a bottom side defining a fourth slit. The second enclosure may be configured to guide a third sound pressure through the third slit, and a fourth sound pressure through the fourth slit. The third and fourths slit may be arranged diagonally opposite the first and second slits, respectively.
