  • Patent number: 11234069
    Abstract: An earbud for detecting biosignals from and presenting audio signals at an inner ear canal and method therefor are disclosed. The earbud includes a nozzle and a housing including a body. The nozzle extends from the housing body and has a proximal end arranged for positioning within an inner ear canal of an individual. An earbud tip of the earbud attaches to the proximal end of the nozzle and is adapted to engage the inner ear canal. The earbud includes a speaker and various sensors including an infrasonic/vibration sensor. The infrasonic/vibration sensor detects the biosignals including infrasonic signals from the body of the individual in the canal, and the speaker transmits sound from an audio source into the canal via the nozzle. The earbud preferably seals the inner ear canal to block external sound while also decreasing an acoustic volume of the canal that amplifies the biosignals prior to detection.

  • Patent number: 11170766
    Abstract: A system has multiple audio-enabled devices that communicate with one another over an open microphone mode of communication. When a user says a trigger word, the nearest device validates the trigger word and opens a communication channel with another device. As the user talks, the device receives the speech and generates an audio signal representation that includes the user speech and may additionally include other background or interfering sound from the environment. The device transmits the audio signal to the other device as part of a conversation, while continually analyzing the audio signal to detect when the user stops talking. This analysis may include watching for a lack of speech in the audio signal for a period of time, or an abrupt change in context of the speech (indicating the speech is from another source), or canceling noise or other interfering sound to isolate whether the user is still speaking.
