Patent number: 11778368Abstract: Array microphone systems and methods that can automatically focus and/or place beamformed lobes in response to detected sound activity are provided. The automatic focus and/or placement of the beamformed lobes can be inhibited based on a remote far end audio signal. The quality of the coverage of audio sources in an environment may be improved by ensuring that beamformed lobes are optimally picking up the audio sources even if they have moved and changed locations.Type: GrantFiled: September 2, 2022Date of Patent: October 3, 2023Assignee: Shure Acquisition Holdings, Inc.Inventors: Dusan Veselinovic, Mathew T.

Patent number: 11770650Abstract: Endfire linear array microphone systems and methods with consistent directionality and performance at different frequency ranges are provided. The endfire linear array microphone includes a delay and sum beamformer and a differential beamformer. The delay and sum beamformer may produce pickup patterns with good directionality at higher frequency ranges, but cause the pickup patterns to become more omnidirectional at lower frequencies. The differential beamformer may produce pickup patterns with good directionality at lower frequencies. By combining the delay and sum beamformer and differential beamformer within the linear array microphone, the overall directionality of the linear array microphone may be maintained at different frequency ranges while using the same microphone elements.Type: GrantFiled: March 30, 2022Date of Patent: September 26, 2023Assignee: Shure Acquisition Holdings, Inc.Inventor: Jordan Schultz

Patent number: 11749910Abstract: A dual band antenna that allows the independent optimization of each frequency band by adjusting the sizes of the antenna elements. For example, an antenna may have two different drivers, one for the high-frequency and one for the low frequency. By using elements orthogonally connected to the low frequency driver, the low frequency driver can function as both a reflector to the high frequency drivers and the low frequency driver without affecting the antenna's performance in the high frequency. The antenna may also have parasitic elements. For example, parasitic directors parallel to the high frequency band driver can be configured to improve performance in the high frequency band. Pairs of additional parasitic directors can be orthogonally connected these directors. These pairs can be adjusted in size to improve performance in the low frequency band with minimal impact on performance in the high frequency band.Type: GrantFiled: September 21, 2021Date of Patent: September 5, 2023Assignee: Shure Acquisition Holdings, Inc.Inventor: Mark Allen Kenkel

Publication number: 20230262878Abstract: A wireless earphone incorporates a wire antenna having a form factor driven innovative antenna shape that minimizes antenna detuning caused by user interactions with the earphones. The wire shape, diameter, and distance of the wire antenna from the printed circuit board (PCB) are selected for an acceptable tradeoff between antenna bandwidth and radiated efficiency. By inserting an end through a through-hole of the PCB, the wire antenna is electrically connected to a multi-layer PCB without traditional approaches such as springs, pogo pins, and the like. An antenna holder further secures the antenna within a thin profile housing for precise placement and manufacturing consistency. A PCB-specific RF VIA geometry is also utilized for partial impedance matching of a transmission line to the wire antenna. In addition, a more constant impedance is maintained along the transmission line connecting a radio device with the wire antenna.Type: ApplicationFiled: April 24, 2023Publication date: August 17, 2023Applicant: Shure Acquisition Holdings, Inc.Inventors: Christopher Zachara, Truong Vu Luu, Christopher Richard Knipstein

Patent number: 11696068Abstract: A microphone may comprise a microphone element for detecting sound, and a digital signal processor configured to process a first audio signal that is based on the sound in accordance with a selected one of a plurality of digital signal processing (DSP) modes. Each of the DSP modes may be for processing the first audio signal in a different way. For example, the DSP modes may account for distance of the person speaking (e.g., near versus far) and/or desired tone (e.g., darker, neutral, or bright tone). At least some of the modes may have, for example, an automatic level control setting to provide a more consistent volume as the user changes their distance from the microphone or changes their speaking level, and that may be associated with particular default (and/or adjustable) values of the parameters attack, hold, decay, maximum gain, and/or target gain, each depending upon which DSP is being applied.Type: GrantFiled: September 30, 2020Date of Patent: July 4, 2023Assignee: Shure Acquisition Holdings, Inc.Inventors: Timothy William Balgemann, Soren Christian Pedersen, James Michael Pessin, Brent Robert Shumard, Lena Lins Sutter, Ryan Jerold Perkofski

Patent number: 11678109Abstract: Offset cartridge microphones are provided that include multiple unidirectional microphone cartridges mounted in an offset geometry. Various desired polar patterns and/or desired steering angles can be formed by processing the audio signals from the multiple cartridges, including a toroidal polar pattern. The offset geometry of the cartridges may include mounting the cartridges so that they are immediately adjacent to one another and so that their center axes are offset from one another. The microphones may have a more consistent on-axis frequency response and may more uniformly form desired polar patterns and/or desired steering angles by reducing the interference and reflections within and between the cartridges.Type: GrantFiled: April 22, 2021Date of Patent: June 13, 2023Assignee: Shure Acquisition Holdings, Inc.Inventors: Brent Robert Shumard, Gregory H.
