Description

Technical Field

[0001] The present invention relates to the field of bone conduction speakers, in particular to bone conduction speakers. Background Art

[0002] Generally speaking, people can hear sounds because air transmits vibrations to the eardrum through the external ear canal. The vibrations formed by the eardrum drive the auditory nerve, thereby perceiving the vibrations of the sound. When working, bone conduction speakers can usually transmit sound to the auditory nerve through the skin, subcutaneous tissue and bones, so that people can hear the sound.

[0003] In the existing market, bone conduction technology is mostly used in the military market. At the same time, with the continuous in-depth research on the technology, it is gradually moving towards people's daily life. Since its sound conduction is achieved by vibration transmission, it has strong anti-interference ability and does not need to receive sound through the external auditory canal for transmission. In daily life, it can receive information from the outside world while freeing both ears. Most of the existing bone conduction speakers are equipped with a transducer component in the shell, and a vibration transmission component connected to the transducer component. The vibration transmission component is used to transmit the vibration generated by the transducer component to the skin that fits the vibration transmission component, and then transmit the sound into the user's ear. However, when the existing bone conduction speakers are performing bone conduction, the fitting surface of the fitting part that fits the skin is mostly a convex arc structure. During the conduction process, it is easily affected by external factors, resulting in poor fitting effect, thereby limiting the sound heard by the user. Summary of the invention

[0017] Specifically, the reinforcement member 12 includes a reinforcement frame 121, and a through groove 122 is formed on the side wall of the reinforcement frame 121 close to the U-shaped connecting frame 11, and the inner diameter of the through groove 112 is larger than the outer diameter of the second external thread adjustment sleeve 34.

When in use, the vibration transmission component 24 can transmit the vibration signal of the transducer component 25 into the cochlea through the speaker fitting 21 and the auricle that fits the speaker fitting 21. During the conduction process of the speaker fitting 21, the inner concave fitting part and the outer convex fitting part fit the skin together, which can increase the area that fits the user's skin, thereby allowing more vibration signals to be transmitted into the cochlea through biological tissues and bones, making the sound heard by the user louder. The outer convex surface of the speaker fitting 21 can protect the inner concave surface, which can effectively prevent the inner concave surface from being affected by external factors, further improving the effect of the speaker and making the sound heard by the user louder.
