Abstract: A portable speakerphone having a housing, a receiving transducer, an electrical cable, a transmitting transducer, and a processor. The receiving transducer is affixed to the housing and is configured to receive a first electrical signal from a mobile device. The electrical cable is coupled to and extends from the housing. The transmitting transducer is affixed to the electrical cable, remote from the housing. Also, the transmitting transducer is configured to transmit a second electrical signal, and the second electrical signal is based in part on the first electrical signal. The processor is configured to suppress acoustic echo by modifying the second electrical signal. The processor is also configured to output the modified second electrical signal to the mobile device. A related method is also disclosed.

Abstract: An audio system having low latency includes a digital audio processor as well as sensor inputs coupled to the processor. The sensor inputs may be microphone inputs. The audio processor operates at the same frequency as the sensor inputs, which is typically much higher than an audio signal provided to the audio processor. In some aspects the audio processor operates as a noise cancellation processor and does not include an audio input.

Abstract: A case having a recessed holding, an acoustic waveguide, and at least one audio transducer device. The recessed holding well is configured to receive and captively hold a stand-alone keyboard within the recessed holding well. The acoustic waveguide is integrated with a bottom cover of the case and between a bottom surface of the case and the recessed holding well. The at least one audio transducer device is coupled to a signal processing device and the acoustic waveguide. The at least one audio transducer device is configured to generate an audible audio output in response to an audio signal output from the signal processing device. The acoustic waveguide is configured to receive the audible audio output and generate an enhanced bass audio output.

Abstract: An acoustic layer is added to a keyboard-type device including: enclosing walls, optionally—one or more microphones, a signal processing device, at least one audio transducer, and an acoustic waveguide. The acoustic layer adjoins one or more internal areas of a keyboard-type device. The signal processing device receives an internal signal from an electronic device either through wires or wirelessly. The signal processing device provides a directive sound enhancement of the audio input signals based on room acoustics, such as reverberation, echo, noise, delay, frequency response, and/or speaker-positional information that is determined by the signal processing device. The audio transducer device generates an audible audio output in response to an audio signal output from the signal processing device. The acoustic waveguide receives the audible audio output and generates an enhanced bass audio output from the acoustic waveguide.

Abstract: A method of calibrating an earphone may include: securing an ANC earphone to a calibration fixture, the calibration fixture including an ear model configured to support the ANC earphone, the ear model having an ear canal configured to anatomically resemble a human ear canal and a concha configured to anatomically resemble a human ear concha, the ear canal extending from the concha to an inner end of the ear canal; generating, with the ANC earphone, an audio signal based on a reference tone; determining a characteristic of the audio signal; comparing the characteristic of the audio signal to a previously determined reference characteristic; and adjusting a gain value of the ANC earphone based on the comparing. Additional methods and apparatus are also disclosed.

Abstract: A fixture for calibrating an active noise canceling (ANC) earphone, the calibration fixture including an ear model and an acoustic path. The ear model is configured to support an ANC earphone and includes an ear canal extending from an outer end of the ear canal to an inner end of the ear canal. The acoustic path is external to the ear canal and extends from, at a first end of the acoustic path, the inner end of the ear canal of the ear model to an opposite, second end of the acoustic path. The acoustic path is configured to transmit a mechanical sound wave received from the inner end of the ear canal to a region external to the ear model and adjacent the outer end of the ear canal.
