Description

Bone conduction headphone charging adapter

Technical field

The utility model belongs to the technical field of bone conduction earphones, and in particular relates to a bone conduction earphone charging adapter.

Background technique

Bone conduction is a sound conduction method that converts electrical signals into mechanical vibrations and transmits the mechanical vibrations through the human skull to the auditory center of the cerebral cortex to achieve the transmission of sound waves. Bone conduction headphones use bone conduction technology to receive calls and are close to the skull. Sound waves can be transmitted directly to the auditory nerve through the bones without going through the external auditory canal and eardrum, which can "liberate" both ears.

Due to their working characteristics, bone conduction headphones are usually suitable for outdoor sports scenes. Since bone conduction headphones are close to the user's head, sweat will soak the bone conduction headphones. Therefore, conventional Type-C or Micro USB interfaces are not suitable for bone conduction headphones.
