Application: Methods, apparatus and systems for audio playback (Patent ID: US20240061921A1)
The patent filed by Cirrus Logic Inc. describes methods, apparatus, and systems for audio playback through a personal audio device following a biometric process. The invention involves using ear model data obtained from a personal audio device to authenticate a user through an ear biometric authentication system. Upon successful authentication, the device is able to identify the user listening to audio playback and implement specific playback settings tailored to that authorized user, enhancing the personalized audio experience. The method involves obtaining ear biometric data, attempting user authentication, and controlling the personal audio device to output audio playback signals with user-specific settings upon successful authentication, while default settings are used in case of unsuccessful authentication. The system also includes additional features such as generating acoustic stimuli, detecting application of the device to the user's ear, and utilizing a microphone for active noise cancellation, enhancing the overall user experience and security of the authentication process.
Overall, the patent outlines a sophisticated system that leverages biometric data from the user's ear to provide a personalized audio playback experience through a personal audio device. By implementing user-specific playback settings upon successful authentication, the device ensures a tailored and secure audio experience for the authorized user. The method also includes additional authentication mechanisms such as pin, passphrase, or voice authentication, further enhancing the security of the system. Additionally, the system's ability to detect application of the device to the user's ear and utilize features like active noise cancellation demonstrates a comprehensive approach to user authentication and audio playback, making it a valuable innovation in the field of personal audio devices.
