    摘要: A coupler includes a first member having a first engagement surface and a second member having a second engagement surface disposed for relative positioning of the first and second members along a line of adjustment. One or more magnetic elements are arranged on the first and second members to establish a magnetic flux between the first engagement surface and the second engagement surface, and thereby establishing a frictional force tending to hold the relative positions of the first and second members. The magnetic flux varies as a function of relative position of the first and second members along the line of adjustment, and has peaks at a plurality of detent positions along the line of adjustment.

    摘要: A wearable media device comprising a substantially U-shaped body configured to be worn around a neck of a user. The U-shaped body includes a left section, right section and middle section. The left section is configured to be disposed on the left side of the neck of the user and includes a first docking port configured to receive a first wireless earbud. The right section is configured to be disposed on the right side of the neck of the user and includes a second docking port configured to receive a second wireless earbud. The middle section couples the left and right sections and is configured to be disposed on the back of the neck of the user.

    摘要: A method for hybrid noise suppression includes receiving a processed audio signal from an audio device. The processed audio signal results from a partial audio processing performed on a noisy audio input signal. The method further includes predicting a noise suppression parameter using a neural network model operating on the processed audio signal and generating a noise-suppressed audio signal from the processed audio signal, using the noise suppression parameter. The method further includes generating a noise-suppressed audio output signal from the noise-suppressed audio signal using an additional audio processing and outputting the noise-suppressed audio output signal.

    摘要: A headset case includes a base providing a cavity for stowing a headset, the base including a bottom region configured to rest on a surface; a lid; and a hinge pivotably connecting the lid to the base. When the headset case is in a closed configuration, the lid covers the cavity. When the headset case is in an open configuration, a first section of the lid at least partially rests on the surface, and a second section of the lid, extending from the first section of the lid, is configured to prop up a smartphone by mechanically supporting the smartphone leaning against the second section of the lid while resting on the base.

    摘要: A method for hybrid noise suppression involves receiving a first processed audio signal and a second processed audio signal from an audio device. The first processed audio signal results from a comprehensive audio processing including a noise spectrum estimate-based noise suppression performed on a noisy audio input signal obtained by the audio device. The second processed signal results from a partial audio processing excluding the noise spectrum estimate-based noise suppression performed on the noisy audio input signal. The method further involves temporally aligning the second processed audio signal with the first processed audio signal, predicting a noise suppression parameter using a neural network model operating on the second processed audio signal after the temporal alignment, generating a noise-suppressed audio output signal from the first processed audio signal after the temporal alignment using the noise suppression parameter, and outputting the noise-suppressed audio output signal.
