Ear Insert Patents (Class 181/135)
  • Patent number: 10652643
    Abstract: Generic adjustable in-ear monitors (IEMs) may suffer from a limited range of resilient ear plugs that may not adequately fit each user, and the user may prefer different ear plugs for different purposes (e.g., the user's interest in secure fitment may be higher when exercising, while the user's interest in comfort may be higher when the user is relaxing). The presently disclosed technology is directed to IEMs that permit a user to adjust without removing and replacing an associated ear plug. Instead, the ear plug is adjustable by the user to achieve a desired fit and may be adjusted repeatedly for different desired fits and/or different users.

  • Patent number: 10623876
    Abstract: The potential to develop disturbing tinnitus may result from repeated unprotected exposure to loud sounds such as rock concerts, machinery, automobile traffic, and crowds at sporting events. Older adults, especially above the age of 50, may be more susceptible to tinnitus resulting from pathologic conditions in the inner ear apparatus. The present device is designed to electronically reduce stressed hearing during the auditory insult and to return to normal function when the insult is removed. No manual adjustment by the user is necessary between these phases. This device is miniaturized to allow wearing it in the outer ear canal during periods of sound excesses and removal at other times. Unlike prior auditory aids, this one acts to block loud noises without the need to remember to place or activate auxiliary devices such as ear plugs to protect against or compete with potentially destructive external factors each time an insult is encountered.

  • Patent number: 10602258
    Abstract: A method for manufacturing a cartilage conduction audio device is disclosed. A manufacturing system receives data describing a three-dimensional shape of an ear (e.g., the outer ear, behind the ear, the concha bowel, etc.) of a user. The system identifies one or more locations for one or more transducers along a back of an auricle of the ear for the user that vibrate the auricle over a frequency range causing the auricle to create an acoustic pressure wave at an entrance of the ear canal. The system then generates a design for a cartilage conduction audio device for the user based on the one or more identified locations of the transducers at which acoustic pressure waves generated by the one or more transducers satisfy a threshold performance metric for the user. The design may then be used to fabricate the cartilage conduction audio device.

  • 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: 9107772
    Abstract: A method and apparatus for filling an expandable in-ear device having in-flow and out-flow canals including a plurality of chambers with elastic membranes in which the components of a settable polymer are held under high relative pressure. The component chambers are connected to a common mixing element which mixes the components before they are applied to the in-flow canal of an in-ear device. A sealed relief chamber is connected to the out-flow canal of the in-ear device and receives excessive mixed compound as it exits the in-ear device. The relief chamber is in contact with the elastic membranes of the component chambers such that when the elastic membranes contract the pressure in the relief chamber decreases, maintaining the pressure within a pre-determined pressure range.
