  • Patent number: 10863035
    Abstract: Presented herein is an audio endpoint for telecommunication operations with increased echo rejection. According to one example, the audio endpoint includes a housing body, an upper speaker assembly, a lower speaker assembly, and at least one microphone assembly. The upper speaker assembly is disposed near a top portion of the housing body and has an effective frequency range above a first frequency. The lower speaker assembly is disposed near a bottom portion of the housing body and has an effective frequency range below a second frequency. The microphone assembly includes a first microphone element and a second microphone element. The first microphone element is above the second microphone element so that they are vertically aligned. The first microphone element has an effective frequency range below the first frequency and the second microphone element has an effective frequency range above the second frequency.

  • Patent number: 10051353
    Abstract: Presented herein is an audio endpoint for telecommunication operations, sometimes referred to herein as a “telecommunications audio endpoint” or, more, simply as an “audio endpoint.” According to at least one example, the audio endpoint presented herein includes a base, a speaker, a speaker waveguide, a microphone waveguide, and two or more microphones. The base is configured to engage a support surface (i.e., a table) and the speaker is configured to emit sounds (i.e., fire) in a direction of the base. The speaker waveguide is disposed between the speaker and the microphone waveguide, while the microphone waveguide is disposed between the speaker waveguide and the base. The two or more microphones are disposed within the microphone waveguide and are proximate to the base. In general, the speaker waveguide is configured to guide sounds output by the speaker in general radially (outward) directions.

  • Patent number: 9485587
    Abstract: In one embodiment, a speaker device assembly includes a first voice coil assembly moveable along an axis of a magnetic field of a magnetic core responsive to an induced current to facilitate pressure variations in a medium, and cause recoil vibration on a speaker device assembly structure. The speaker device assembly further includes a second voice coil assembly having a counter balance mass that accounts for at least a mass of the first voice coil assembly, and moveable along the axis of the magnetic field in a direction opposite the first voice coil assembly to attenuate the recoil vibration on the speaker device assembly structure, when the first voice coil assembly moves along the axis of the magnetic field.

  • Publication number: 20140270310
    Abstract: In one embodiment, an apparatus includes a network interface, an acoustic waveguide, and an arrangement. The network interface is arranged to communicate on a network, and is further configured to obtain a signal from the network. The arrangement is configured to transform the signal into an acoustic wave and to provide the acoustic wave to the acoustic waveguide. The acoustic waveguide is configured to direct the acoustic wave in a path.
