ACOUSTIC DETECTION OF IN-EAR HEADPHONE FIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18346152 titled 'ACOUSTIC DETECTION OF IN-EAR HEADPHONE FIT

Simplified Explanation

The abstract describes a method performed by an in-ear headphone that involves obtaining an audio signal from an audio source device and using it to drive a speaker in the headphone to output sound into the user's ear canal. The method also obtains a microphone signal that is responsive to the outputted sound and notifies the user to replace the ear tip with a different one if the microphone signal falls below a certain threshold.

  • The in-ear headphone is coupled with a first ear tip that is inserted into the user's ear canal.
  • The audio signal is obtained from an audio source device that is paired with the in-ear headphone.
  • The obtained audio signal is used to drive a speaker in the headphone, which then outputs sound into the user's ear canal.
  • A microphone signal is obtained, which is responsive to the sound that is outputted into the ear canal.
  • If the parameter associated with the microphone signal falls below a threshold, the user is notified to replace the first ear tip with a second ear tip.

Potential applications of this technology:

  • Personal audio devices: This method can be used in in-ear headphones for personal audio devices such as smartphones, MP3 players, and tablets.
  • Communication devices: In-ear headphones with this method can be used for communication devices like hands-free headsets for phone calls or voice assistants.
  • Gaming and virtual reality: This technology can enhance the audio experience in gaming headsets or virtual reality headsets, providing more immersive sound.

Problems solved by this technology:

  • Improving sound quality: By using the microphone signal to monitor the sound output, the method ensures that the ear tip is properly fitted and provides optimal sound quality.
  • Comfort and fit: The method notifies the user to replace the ear tip if the microphone signal falls below a threshold, indicating a poor fit. This helps in ensuring comfort and a secure fit for the user.

Benefits of this technology:

  • Enhanced user experience: By monitoring the microphone signal and notifying the user to replace the ear tip if needed, the method ensures that the user receives optimal sound quality and comfort.
  • Customization: The ability to replace ear tips allows users to choose the most suitable size and material for their ears, enhancing the overall experience.
  • Longevity: By notifying the user to replace the ear tip when necessary, the method helps prolong the lifespan of the in-ear headphone by preventing potential damage or degradation caused by a poor fit.


Original Abstract Submitted

A method performed by an in-ear headphone. Coupled to the in-ear headphone is a first ear tip that is inserted into an ear canal of a user. The method obtains an audio signal from an audio source device paired with the in-ear headphone and uses the signal to drive a speaker of the headphone to output a sound into the ear canal. The method obtains a microphone signal that is responsive to the outputted sound. The method notifies the user to replace the first ear tip with a second ear tip in response to a parameter associated with the microphone signal being less than a threshold.
