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 personal audio device obtains ear model data to authenticate a user via an ear biometric authentication system, allowing the device to implement specific playback settings for the authorized user. This process involves obtaining ear biometric data based on the user's ear response to an acoustic stimulus, attempting user authentication, and controlling the audio device to output personalized audio playback based on the successful authentication. The system can also revert to default settings if authentication fails. Additional features include using the microphone for noise cancellation, generating acoustic stimuli, and implementing various user-specific playback settings like audio equalization, secure messages, and voice assistant privacy modes.
The patent further details a method for user authentication using a personal audio device, where the device detects application to the user's ear, obtains ear biometric data based on ear response to acoustic stimuli, and authenticates the user based on this data. Upon detecting an event requiring audio playback, additional ear biometric data is obtained, and authentication is attempted using both sets of data. Successful authentication results in the controlled output of audio playback to the user. This method allows for continuous monitoring of user authentication based on ear biometric data and the application of personalized playback settings. The system also includes provisions for additional authentication mechanisms like pin, passphrase, or voice authentication, as well as features like music playback, audible notifications, and text-to-speech output.
