  • Patent number: 10791389
    Abstract: An ear-plug assembly is implemented as part of an audio system to present a user with improved audio content. The audio system uses an acoustic conduction system to provide audio content to the user using tissue (e.g., bone and/or cartilage) born acoustic pressure waves. The ear-plug assembly mitigates leakage of low frequency components of airborne acoustic waves generated within the ear canal from the ear. The acoustic conduction system adjusts how content is presented based in part on the presence of the ear-plug assembly within the ear. In some embodiments, the ear-plug assembly may include one or more microphones (external and/or internal), and the acoustic conduction system adjusts how content is presented based on the signals detected by the one or more microphones.
