Patent attributes
Embodiments of the present disclosure generally relate to custom-fit in-ear audio devices. The custom-fit earpieces disclosed herein may include features providing superior retention in a user's ear while also maintaining desirable comfort and sound quality. The superior retention is generally provided by a curable filler disposed in a bladder that is deformed to conform to the shape of a user's outer ear as the filler material is cured. It has been found that a desired comfort level and sound quality can be achieved in a custom-fit earpiece by physically separating or at least partially decoupling the audio output member from other portions of the earpiece that are designed to enable the retention of the custom-fit earpiece within the user's ear. In some configurations, one of the portions of the custom-fit earpiece that is designed to enable the retention of the custom-fit earpiece within the user's ear includes a curable filler material that is disposed within a bladder that is coupled to a portion of the custom-fit earpiece.
