Abstract
In accordance with some embodiments, an apparatus for privacy protection is provided. The apparatus includes an audio output device arranged to output sound directed to an audio input device of a second device. The apparatus further includes an audio coupling interface arranged to provide a cavity for the audio output device and the audio input device of the second device. The apparatus also includes a spectral shaper, coupled to the audio output device, operable to apply a spectral envelope to an audio signal in order to produce a shaped audio signal, wherein the shaped audio signal is selectively coupled to the audio output device.
Claims20
An apparatus comprising:
- a housing arranged to hold a second device;
- an audio output device, arranged to output sound directed to an audio input device of the second device;
- an audio coupling interface, coupled to the audio output device and mateable with the audio input device of the second device, arranged to provide part of an audio-sealing pathway connecting the audio output device and the audio input device of the second device when mated with the audio input device of the second device;
- and
- a spectral shaper, coupled to the audio output device, operable to shape an audio signal into a shaped audio signal, wherein the shaped audio signal is selectively coupled to the audio output device.
A method comprising:
- at a first device with a housing arranged to hold a second device, the first device includes an audio output device, an audio coupling interface coupled to the audio output device and mateable with an audio input device of the second device, and a spectral shaper:
- obtaining an audio signal from the first device;
- applying a spectral envelope to the audio signal in order to produce a shaped audio signal;
- selectively coupling the shaped audio signal to the audio output device of the first device via an audio-sealing pathway connecting the audio output device and the audio input device of the second device when the audio coupling interface is mated with the audio input device of the second device;
- and
- causing the audio output device to output sound as a function of the shaped audio signal directed to the audio input device of the second device.
