Description

In-ear hybrid bone conduction headphones

Technical Field

The utility model relates to the field of earphones, in particular to an in-ear hybrid bone conduction earphone.

Background Art

With the development of audio technology, bone conduction headphones, as a type of headphones that do not require air conduction, have gradually gained popularity among users due to their unique advantages. Bone conduction headphones avoid the limitations of air conduction headphones in noisy environments by directly transmitting sound vibrations to the user's bones. However, existing in-ear bone conduction headphones, when mixing various sound units, mostly use other units for the main sound conduction, such as dynamic units, moving iron units, electrostatic units, etc. In-ear headphones containing bone conduction units, most of them are directly attached to the inside of the shell, or use channels to conduct sound into the ear canal for air conduction, thus failing to conduct bone conduction in an effective manner, resulting in a serious lack of efficiency in the use of bone conduction units.
