Description

Technical Field

[0001] This utility model relates to the field of bone conduction headphones, specifically a bone conduction feedback headphone with sound direction feedback function. Background Technology

[0002] Bone conduction headphones are headphones that transmit sound using bone conduction technology. They convert sound into mechanical vibrations, which are then transmitted directly to the inner ear through the skull and other skeletal structures, stimulating the auditory nerve to produce hearing. These headphones do not require insertion into the ear canal, keeping both ears open and allowing users to remain aware of their surroundings while listening to music, thus improving safety. Due to their unique sound transmission method and convenient user experience, bone conduction headphones are widely popular among sports enthusiasts and people who need to maintain environmental awareness.

[0003] While existing bone conduction headphones offer a convenient audio experience for many users, they suffer from significant shortcomings in sound direction feedback, especially for the hearing impaired. Because bone conduction headphones transmit sound through vibrations of the skull, rather than the air conduction method of traditional headphones, users often cannot determine the direction of a sound source by observing the difference in sound received by their left and right ears, as they can with regular headphones. This undoubtedly increases the inconvenience for the hearing impaired in daily communication and activities. They may be unable to accurately determine the location of others, leading to difficulties in social interactions. Utility Model Content
