Description

A sunglasses that can flexibly adjust the position of a bone conduction earphone

Technical field

The present application relates to a sunglass that can flexibly adjust the position of a bone conduction earphone, and belongs to the technical field of wearable devices.

Background technique

Most of the sunglasses currently in use are simple in design and single in function, and are mainly used for outdoor or driving to block strong light irradiation. However, such sunglasses do not have a headphone function, for example, the user cannot directly pass through the outdoors or when driving. Sunglasses listen to music or make calls, especially when the phone calls, the user can not pick up the phone or headset to answer the phone immediately. If the headset is installed in the sunglasses that have been worn, the driver can answer the phone conveniently and safely. Therefore, there is a need for a pair of sunglasses that can integrate headphones with UV protection.

Although there are sunglasses with earphones in the prior art, most of them are earphones that are conducted through air. The earphones transmit sound to the eardrum through air vibration, and then pass through the eardrum to the ear nerves, thereby enabling the user to When you hear the sound, the user needs to put the earphone in the ear when using it, which brings a series of problems: (1) When the age becomes large or the lesion, the performance of the human eardrum decreases, it will cause hearing impairment to the person; (2) Using this kind of earphone can't hear the outside world, it is easy to be dangerous when driving or crossing the road; (3) Use this kind of earphone for a long time and at high volume, it will affect people's eardrum, it will cause people's tinnitus, which will seriously cause Hearing declines. The bone conduction earphone does not need to be stuck in the ear hole or plugged in the ear hole, and the sound conduction does not need the vibration of the ear film, which improves the comfort and protects the user's hearing, and allows the user to directly hear the external sound. Unique superiority.
