  • Patent number: 10484788
    Abstract: An acoustic transducer includes a passive diaphragm and an active diaphragm. The active diaphragm electromechanically couples to an electric drive element and the passive diaphragm is configured to acoustically couple with pressure changes induced by excursions of the active diaphragm. The active diaphragm has an outer perimeter and an inner perimeter, with the X-Y (horizontal) points on the outer perimeter of the passive diaphragm coinciding on or within X-Y points on at least the outer perimeter of the active diaphragm over a common, orthogonal Z coordinate so that the passive diaphragm projects a shape that falls on or within an area of the active diaphragm. In some cases, the inner perimeter of the active diaphragm may define a bounded area for the active diaphragm, the passive diaphragm having an outer perimeter that axially, superimpositionally coincides on or within the inner perimeter of the bounded area.

  • Patent number: 10463476
    Abstract: Presented herein are signal processing techniques that integrate an adaptive filtering process with a parametric post-filter in the frequency domain to control the amount of body noise reduction in each of a plurality of frequency bands (e.g., tuneable body noise reduction in each frequency band). The parametric post-filter generates a gain mask that is tuned to responses of sensors to separate external acoustic sounds and body noises, while limiting distortions of own voice. The techniques presented herein can preserve external acoustic sound quality, attenuate own voice to a comfortable level without distortion, suppress body noises, and/or lower a noise floor of the output signal.

  • Patent number: 10462562
    Abstract: The article of invention is referred herein as a prime polygon reflector. In its various forms it is a device of predetermined geometric shape with aspects and scalable dimensions derived from a prime number and its mathematical square root. Geometric shapes based on the prime polygon have reflective surfaces that cause multiple internal reflections of incident waveform energy. When used in conjunction with absorptive media, coatings, or linings, the waveform energy is forced to pass through absorptive media multiple times, thereby increasing effectiveness of the media, coating, or lining. Prime polygon reflectors as disclosed herein produce waveform reflections that are non-inverted by causing an even number of internal reflections. Applications include but are not limited to acoustic, solar, and radar energy absorption.
