Publication number: 20190182585Abstract: An acoustic layer is added to a laptop-type personal computing device, comprising: 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 laptop-type device. The signal processing device receives an internal signal from a laptop-type device. 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.Type: ApplicationFiled: November 8, 2018Publication date: June 13, 2019Inventors: Patrick A. Quinn, Robert C. Proebstel, Manpreet S. Khaira, Thomas Irrgang, Nigel D. Waites, Ian J. Myles

Patent number: 9894438Abstract: 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.Type: GrantFiled: October 14, 2016Date of Patent: February 13, 2018Assignee: AVNERA CORPORATIONInventors: Amit Kumar, Thomas Irrgang, Xudong Zhao
