SEAMLESS LISTEN-THROUGH BASED ON AUDIO ZOOM FOR A WEARABLE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18063493 titled 'SEAMLESS LISTEN-THROUGH BASED ON AUDIO ZOOM FOR A WEARABLE DEVICE

Simplified Explanation

The wearable device described in this patent application includes a processor that performs active noise cancellation (ANC) on an input audio signal received by a microphone. It also detects a self-voice signal using one or more transducers.

  • The processor applies a first filter to an external audio signal detected by an external microphone on the wearable device during a listen through operation.
  • This filter is activated when the audio zoom feature is turned on, and it generates a first listen-through signal that includes the external audio signal.
  • After the audio zoom feature is activated, the processor terminates a second filter that provides low frequency compensation.
  • The processor then produces an output audio signal based on the first listen-through signal that includes the external signal and the detected self-voice signal.

Potential Applications

  • This technology can be used in wearable devices such as headphones or earbuds to provide active noise cancellation and audio zoom features.
  • It can enhance the listening experience by reducing background noise and allowing the user to focus on specific sounds or conversations.

Problems Solved

  • The active noise cancellation feature helps to block out unwanted noise, improving the clarity of the audio signal.
  • The audio zoom feature allows the user to selectively amplify specific sounds or conversations, making it easier to hear in noisy environments.

Benefits

  • The wearable device with active noise cancellation and audio zoom features provides a more immersive and personalized audio experience.
  • It allows the user to control the level of ambient noise and focus on desired sounds or conversations.
  • The technology can be applied to various wearable devices, making it versatile and adaptable to different user preferences and needs.


Original Abstract Submitted

A wearable device may include a processor configured to perform active noise cancelation (ANC) applied to an input audio signal received by at least one microphone, and detect a self-voice signal, based on one or more transducers. The processor may also be configured to apply a first filter to an external audio signal, detected by at least one external microphone on the wearable device, during a listen through operation based on an activation of the audio zoom feature to generate a first listen-through signal that includes the external audio signal. The processor may also be configured to after the activation of the audio zoom feature terminate a second filter that provides low frequency compensation. The processor may be configured to produce an output audio signal that is based on at least the first listen-through signal that includes the external signal, and is based on the detected self-voice signal.
