Description

A bone conduction wired earphone

technical field

The utility model relates to the technical field of earphones, in particular to a bone conduction wired earphone.

Background technique

Under normal circumstances, there are two main ways for the human body to hear sound: air conduction and bone conduction. Therefore, the earphones currently on the market can also be divided into air conduction earphones and bone conduction earphones by transmission methods. The principle of air-conduction earphones is that the sound causes the air to vibrate, and the vibration is transmitted to the middle ear tympanic membrane through the external auditory canal, and the vibration of the tympanic membrane is finally transmitted to the cochlea auditory nerve, so that people can perceive the sound. When this earphone is working, it is necessary to cover the ear hole with the earphone. In contrast, bone conduction earphones transmit sound directly to the cochlear auditory nerve through human tissues such as bones, skin and muscles, so that people can perceive the sound. Since there is no need to pass through the tympanic membrane of the middle ear, it is no longer necessary to place any foreign matter in the user's ear, and the ears can be kept open so that the ambient sound can be heard, so the user's personal safety is better guaranteed during the use of the earphone.

The left bone conduction plastic mechanism and the right bone conduction plastic mechanism are arranged on the main body of the earphone, and the two sections of the earphone rear hang are respectively connected with the left bone conduction plastic mechanism and the right bone conduction plastic mechanism. Through the partial details disclosed in the appearance patent, combined with the existing technology in the field of earphones, it can also be concluded that the bone conduction speakers are respectively installed at the lower ends of the left bone conduction plastic mechanism and the right bone conduction plastic mechanism, and there is a power supply outside the right bone conduction plastic mechanism The button contains the motherboard for circuit control, and the left bone conduction plastic mechanism contains batteries in the corresponding position to supply power to the earphones.
