  • Publication number: 20220109933
    Abstract: A head-worn sound reproduction device is provided in the form of left and right earphones, which can either be clipped to each ear or mounted on other headgear. The earphones deliver high fidelity audio to a user's eardrums from near-ear range, in a lightweight form factor that is fully “non-blocking” (allows coupling in and natural hearing of ambient sound). Each earphone has a woofer component that produces bass frequencies, and a tweeter component that produces treble frequencies. The woofer outputs the bass frequencies from a position close to the ear canal, while the tweeter outputs treble frequencies from a position that is either close to the ear canal or further away. In certain embodiments, the tweeter is significantly further from the ear canal than the woofer, leading to a more expansive perceived “sound stage”, but still with a “pure” listening experience.

  • Patent number: 11240622
    Abstract: A dual source spatialized audio system includes a general audio system and a personal audio system. The general system includes a general audio processor and general speakers to produce general sound. The personal system includes a frame to be worn on a head of a user and a plurality of personal speakers attached to the frame. The personal system also includes a head pose sensor to collect head pose data of the user. The personal system further includes a head pose processor to determine a head pose of the user from the head pose data. Moreover, the personal system includes a personal audio processor to generate personal audio data based on the head pose of the user. The personal speakers generate personal sound corresponding to the personal audio data. The personal processor receives timing information/metadata from the general audio processor to synchronize the personal sound with the general sound.

  • Publication number: 20210306751
    Abstract: Disclosed herein are systems and methods for processing speech signals in mixed reality applications. A method may include receiving an audio signal; determining, via first processors, whether the audio signal comprises a voice onset event; in accordance with a determination that the audio signal comprises the voice onset event: waking a second one or more processors; determining, via the second processors, that the audio signal comprises a predetermined trigger signal; in accordance with a determination that the audio signal comprises the predetermined trigger signal: waking third processors; performing, via the third processors, automatic speech recognition based on the audio signal; and in accordance with a determination that the audio signal does not comprise the predetermined trigger signal: forgoing waking the third processors; and in accordance with a determination that the audio signal does not comprise the voice onset event: forgoing waking the second processors.

  • Patent number: 5734713
    Abstract: A method and system for remotely calibrating a headset telephone with a reliable, accurate and easy to use user interface is provided. This method makes use of the remote programmability of advanced telephone headsets and DTMF signal encoding and permits the customer-user to instigate the calibration procedure with an ordinary telephone call. The invention provides the means by which the optimum settings can be transmitted to the headset, loaded and stored in the headset, thereby improving the audio quality of telephone headsets by providing adjustment steps for such audio qualities as microphone gain (transmit level), speaker gain, background noise and echo cancellation, filter functions and diagnostics. This method also provides audio feedback to a customer service representative performing the calibration to insure that the commands and adjustments were properly received.
