摘要： An apparatus, system and method for a portable microphone array system comprising a computing device and a case having an array of microphones embedded or integrated into the case. A user may position the laptop and case facing the general direction of a target audio source to capture a target acoustic audio input at the microphone array. The microphone array may deliver a first stage of beamformed audio from the acoustic audio input to the computing device via a communications interface or bus. The computing device may comprise an audio processor configured to perform one or more successive audio processing steps to process the audio input and render a digital audio output. The digital audio output may be outputted from the computing device to an audio output device, such as headphones or an earpiece.

摘要： A spatial audio processing system operable to enable audio signals to be spatially extracted from, or transmitted to, discrete locations within an acoustic space. Embodiments of the present disclosure enable an array of transducers being installed in an acoustic space to combine their signals via inverting physical and environmental models that are measured, learned, tracked, calculated, or estimated. The models may be combined with a whitening filter to establish a cooperative or non-cooperative information-bearing channel between the array and one or more discrete, targeted physical locations in the acoustic space by applying the inverted models with whitening filter to the received or transmitted acoustical signals. The spatial audio processing system may utilize a model of the combination of direct and indirect reflections in the acoustic space to receive or transmit acoustic information, regardless of ambient noise levels, reverberation, and positioning of physical interferers.

摘要： An apparatus for enhancing microphone performance of a voice-controlled smart home device is disclosed. The apparatus generally comprises a lower ring having a first diameter an upper ring having a second diameter and a reflective surface. The reflective surface is disposed along the perimeter of the apparatus so as to directionally alter incoming sound waves and focus them toward an array of microphones.

摘要： A directional microphone array which can be integrated into a case for a portable computing device. A microphone array board connects to a surface of a laptop computer, tablet computer or smart phone, which can be steered in the direction of a target source. An audio processing module (APM) is operably engaged with the array board to receive a first staged beamformed audio input from the array board, and process a second beamformed stage audio output.

摘要： A wearable, shoulder-mounted microphone array apparatus and system used as a bi-directional audio and assisted listening device system. The present invention advances hearing aids and assisted listening devices to allow construction of a highly directional audio array that is wearable, natural sounding, and convenient to direct, as well as to provide directional cues to users who have partial or total loss of hearing in one or both ears. The advantages of the invention include simultaneously providing high gain, high directivity, high side lobe attenuation, and consistent beam width; providing significant beam forming at lower frequencies where substantial noises are present, particularly in noisy, reverberant environments; and allowing construction of a cost effective body-worn or body-carried directional audio device.

摘要： A directional waveguide array apparatus can transmit and/or receive airborne or fluid-borne audio with the appropriate selection of transducers. The present invention advances directional waveguide arrays by allowing construction of a directional audio device with desired frequency bandwidths, array patterns, and gain by appropriate geometric configurations of the array of waveguide channel ports, as well as dimensioning and configuration of waveguide channel and chamber parameters. Embodiments of the present invention enable increased immunity to environmental noises, temperature, and humidity; low cost of construction; high reliability; simplicity of operation; very low power consumption; real-time steering of directivity (interference) pattern; wide range of audio powers that can be transmitted or received; and interchangeable transducer types.
