METHOD AND APPARATUS FOR EARPIECE AUDIO FEEBACK CHANNEL TO DETECT EAR TIP SEALING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240031728 titled 'METHOD AND APPARATUS FOR EARPIECE AUDIO FEEBACK CHANNEL TO DETECT EAR TIP SEALING

Simplified Explanation

The abstract describes an earpiece that includes a housing with a sound output channel connected to a speaker. It also has an ear canal feedback channel alongside the sound output channel, connected to a microphone and a digital signal processor (DSP). The DSP includes a voice activity detection module to distinguish between audio played by the speaker and external ear canal noise captured by the microphone. An audio processor receives the detected external ear canal noise and generates an opposite waveform to reduce the noise.

  • The earpiece has a housing with a sound output channel and a speaker.
  • It also has an ear canal feedback channel alongside the sound output channel.
  • The ear canal feedback channel is connected to a microphone and a DSP.
  • The DSP includes a voice activity detection module to distinguish between speaker audio and external ear canal noise.
  • An audio processor receives the detected external ear canal noise and generates an opposite waveform to reduce the noise.

Potential applications of this technology:

  • Noise cancellation in earpieces or headphones.
  • Improved audio quality during phone calls or audio playback.
  • Enhanced communication in noisy environments.

Problems solved by this technology:

  • Reduction of external ear canal noise, improving audio clarity.
  • Minimization of background noise during phone calls or audio playback.
  • Enhanced user experience by reducing distractions caused by external noise.

Benefits of this technology:

  • Improved audio quality and clarity.
  • Enhanced user experience by reducing unwanted noise.
  • Better communication in noisy environments.


Original Abstract Submitted

an earpiece includes a housing including a sound output channel operatively coupled to a speaker formed within the housing. an ear canal feedback channel is formed extending alongside the sound output channel and operatively coupled to a microphone formed within the housing and a dsp operatively coupled to the microphone, the dsp including a voice activity detection module to detect a microphone audio data stream and discern between host audio data stream of audio played by the speaker and external ear canal noise captured in the microphone audio data stream at the microphone at the ear canal feedback channel. an audio processor receives the detected external ear canal noise and generate audio data descriptive of an opposite waveform to the detected external ear canal noise to playback and reduce the detected external ear canal noise.
