  • Patent number: 10425719
    Abstract: A speaker assembly broadly comprising a housing, an input circuit, and a number of speakers. The housing includes a lower section configured to be positioned at least partially below a ground surface and an upper section extending upwards from the lower section. The input circuit receives audio signals from a sound system or other controller and actively or passively sends the audio signals to the speakers. The speakers include a low-range speaker positioned in the lower section of the housing and a relatively higher-range speaker positioned in the upper section. The speaker assembly is configured to be spaced from other speaker assemblies within a listening area with each speaker assembly generating low frequency soundwaves and relatively higher-frequency soundwaves. This reduces or eliminates out-of-phase crossover frequency wave cancellation effects within the listening area.

  • Patent number: 10390141
    Abstract: A loudspeaker diaphragm (12) comprising a woven fiber body supports damping material (25), for example PVA polymer, on a rearward-facing surface (24). The woven fiber body may be formed of lengths (14) non-metallic fiber material (for example glass fiber) coating with a thin metal coating (32). The mass of the layer of damping material (25) may be significantly greater than the mass of the woven fiber body. An attractive sparkly looking loudspeaker diaphragm (12) may thus be provided which damps undesirable vibration while providing a flatter frequency-response curve (50).

  • Patent number: 10390154
    Abstract: A sound processor assembly having a coil support device which allows for the coil to be moved without damaging the plastic components or deforming the shell body. This is done by making the ear shell of the sound processor assembly, whether an integrated sound processor assembly or a linked sound processor assembly, out of two separate polymers: a first polymer that does not soften when heat is applied, and a second polymer which does. The first polymer is used for the first polymer zone of the shell which is shaped to the ear canal, while the second polymer is used for the section of the shell which supports the coil. This allows the shell to be heated, thereby softening the second polymer but not the first, and allows the coil to be repositioned to a new location.

  • Patent number: 10366700
    Abstract: Embodiments of the disclosure generally include a method and apparatus for receiving and separating unwanted external noise from an audible input received from an audible source using an audible signal processing system that contains a plurality of audible signal sensing devices that are arranged and configured to detect an audible signal that is received from any position or angle within three dimensional space. The audible signal processing system is configured to analyze the received audible signals using a first signal processing technique that is able to separate unwanted low frequency range noise from the received audible signal and a second signal processing technique that is able to separate unwanted higher frequency range noise from the received audible signal. The audible signal processing system can then combine the signals processed by the first and second signal processing techniques to form a desired audible signal that has a high signal-to-noise ratio throughout the full speech range.
