AI Technical Summary
Existing binaural recording devices that insert into the ear canal block the ear canal, making it difficult for users to hear surrounding sounds, and can be uncomfortable due to varying ear canal diameters and weak earpiece retention.
An acoustic device with a curved frame that clamps the auricle from both sides, positioning a microphone on the front side of the concha cavity outside the ear canal, allowing for clear hearing of surroundings and improved comfort and fit.
The device allows users to clearly hear surrounding sounds without blocking the ear canal, provides a comfortable fit regardless of ear canal diameter, and maintains secure attachment during user movements.
