    Abstract: An audio device includes a housing having first and second support surfaces for supporting the device at different orientations relative to the surface on which the device is placed, a driver to output sound in a radiating pattern associated with a first axis of the driver, and an orientation sensor to detect a direction of a force of gravity. A control circuit coupled to the driver and the orientation sensor determines the direction of the force of gravity relative to the first axis and whether the first axis is oriented to one of a first angle of elevation associated with physically supporting the device by the first surface and a second angle of elevation associated with physically supporting the device by the second surface. The circuit can alters the output by the driver based on the first axis being oriented to the first or second angles of elevation.

    Abstract: An audio signal processing method and apparatus and a differential beamforming method and apparatus to resolve a problem that an existing audio signal processing system cannot process audio signals in multiple application scenarios at the same time. The method includes determining a super-directional differential beamforming weighting coefficient, acquiring an audio input signal and determining a current application scenario and an audio output signal, acquiring, a weighting coefficient corresponding to the current application scenario, performing super-directional differential beamforming processing on the audio input signal using the acquired weighting coefficient in order to obtain a super-directional differential beamforming signal in the current application scenario, and performing processing on the formed signal to obtain a final audio signal required by the current application scenario. By using this method, a requirement that different application scenarios require different audio signal processing manners can be met.
