Principle and application scenario of bone conduction earphone

Bone conduction headphones are a very special type of Bluetooth headset that transmits sound directly to the inner ear using bone conduction technology. This technology differs from traditional headphones in that it does not transmit sound through the air, but through vibrations in the skull.

The sound transmission principle of bone conduction headphones is different from that of traditional headphones, which transmit sound into the eardrum through air vibration, while bone conduction headphones transmit sound directly to the inner ear through the human bone, eliminating many steps of sound wave transmission.

Specifically, the bone-conducting ear transmits sound through vibration to the skull, and then through the skull to the inner ear, which directly stimulates the auditory nerve in the inner ear, so that people can hear the sound, for example: when we eat nuts, crackers and other hard and brittle foods, do we hear the sound of jaw chewing? This sound is transmitted through the bones of the teeth to the nerves of the ear, which makes people hear the sound of chewing food.
Due to the characteristics of bone conduction headphones that are not worn in the ear and special sound transmission methods, there are many scenarios that can be used, such as sports and outdoor activities (such as running and cycling), offices or workplaces, and the use of the hearing impaired. And some bone conduction headphones have a certain waterproof function, so they can be used in swimming scenes. In addition, riding and driving vehicles can also be used, because the use of bone conduction headphones will not block out ambient sound, so driving or riding can be safe while listening to music or answering the phone.
