Hearing device with active vent for sound transmission control
A recently filed patent (Publication Number: US20230319494A1) describes a new hearing device design. The device includes an earmould that has a front end, a rear end, and a middle part. The front end of the earmould faces the user's tympanic membrane and has a front opening that connects to the outside of the ear canal. The earmould also contains a receiver housing that accommodates a receiver. The receiver housing has a first end and a second end, with the front opening of the earmould closer to the first end. A sound passage extends from the front opening to the rear end of the earmould.
The patent also mentions an active vent located between the second end of the receiver housing and the front opening of the earmould. When the active vent is open, it allows sound transmission through the sound passage, and when it is closed, it hinders sound transmission. The device includes a supporting structure that keeps the receiver housing in place with respect to the earmould.
Additional features of the hearing device include a middle part of the earmould that conforms to the user's ear canal, a removable receiver housing, and a receiver housing that contains the active vent. The active vent is coupled to the receiver housing and held in place within the earmould by the supporting structure. The supporting structure may be made of a softer material than the middle part of the earmould and can include materials such as silicone rubber, TPE, TPA, EPDM, LSR, or a combination of these.
The supporting structure may have one or more openings, an inner wall of the earmould, or a gripper to hold a wire extending from the receiver. It can also extend from an inside wall of the earmould and partially surround the receiver housing. The supporting structure is flexible and can stretch to accommodate the receiver housing during insertion and hold it in place afterward. It is also designed to suspend the receiver housing that is partly in the earmould. The receiver housing and/or the active vent can be removably attached to the supporting structure. Additionally, the receiver housing may include a biometric sensor, and the active vent may have a valve that forms part of the sound passage.
