Description

Technical Field

[0001] The present invention relates to the technical field of bone conduction earphones, and in particular to a neck-hanging bone conduction earphone that is comfortable to wear. Background Art

[0002] Bone conduction headphones are headphones that use the principle of bone conduction to transmit sound signals. Traditional headphones transmit sound signals through air vibrations, while bone conduction headphones transmit sound signals by vibrating the skull and facial bones. It converts sound wave signals into mechanical vibration signals, and then transmits them to the auditory receptors through vibrations, thereby directly stimulating the auditory nerves to achieve the effect of hearing sounds. Bone conduction headphones have some unique advantages over traditional headphones. First, they do not completely isolate external sounds, so they can stay safe during fast movements and exercise. Second, since bone conduction headphones do not have earplugs directly inserted into the ear canal, they can avoid ear canal infections and hinder people's external perception. When wearing them, they open both ears and do not block the ears, which solves the discomfort of wearing in-ear headphones. At the same time, it also avoids a series of hygiene and health problems caused by sweating in the ears when wearing headphones for exercise. Therefore, bone conduction speaker headphones are very suitable for sports use; opening both ears also ensures the possibility of using headphones in dangerous scenarios. By opening both ears, you can notice changes in the surrounding environment while using headphones, which makes it safer to use. However, the structure of bone conduction headphones on the market is simpler than the traditional one. It is not convenient to adjust the clamping strength of the headphone neck hanger, and it is impossible to ensure that the bone conduction headphones are worn closely to the skin.
