  • Patent number: 11877110
    Abstract: Aspects describe air flow relief features in the cosmetic surface of the housing of an in-ear audio output device. Due to design constraints based, at least in part, on the limited space available in the acoustic chamber and ear geometry, ports coupling the acoustic chamber with an area outside the housing are susceptible to full blockage when placed in-ear. Air flow relief channels for ports, extending from the port aligned in the concha cymba, over the helix crus, to the cymba cavum minimize complete blockages of the port as compared to current designs.
    Type: Grant
    Filed: January 13, 2022
    Date of Patent: January 16, 2024

  • Patent number: 10779077
    Abstract: An apparatus includes a printed wiring board (PWB) that defines an aperture. A microphone is mounted on the PWB such that the aperture provides an acoustic path to the microphone. An acoustic interface member defines a cavity that is acoustically coupled to the microphone via the aperture. A first gasket between the printed wiring board and the acoustic interface member forms an acoustic seal. A housing is included, and a second gasket is disposed between the acoustic interface member and the housing to form an acoustic seal. An acoustic chamber is defined by a sealed volume that extends from a first (bottom/inner) surface of the housing down to a junction between the microphone and the PWB. The housing defines apertures which provide an acoustic path between a region external to the housing and the acoustic chamber. The acoustic chamber and the apertures in the housing form a Helmholtz resonator.
