Background
Bone conduction is a sound conduction mode, that is, sound is converted into mechanical vibration with different frequencies, and sound waves are transmitted through the skull, the bone labyrinth, the lymph fluid of the inner ear, the spiral organ and the auditory center of a human body. Compared with a classical sound conduction mode of generating sound waves through a vibrating diaphragm, the bone conduction mode omits a plurality of sound wave transmission steps, can realize clear sound restoration in a noisy environment, and does not influence other people due to the fact that the sound waves are diffused in the air.

This bone conduction earphone hang 3 after including elastic tube 31 and hold memory skeleton 32 of locating in elastic tube 31, can prevent that the user from touching after 3 in the motion process and leading to the damage, have the memory function again, hang 3 in order to adapt to the user of head variation in size after being convenient for adjust and use. Furthermore, the elastic tube 31 is made of a commercially available thermoplastic elastomer, and the outer diameter of the elastic tube is 0.5-1cm, so that compared with the rear hanger 3 made of a traditional metal shell, the elastic tube is lighter and more portable, occupies less space, and is more beneficial to improving the experience of a user in the exercise process.
In the present embodiment, the memory skeleton 32 is a memory alloy.
By adopting the technical scheme, the rear hanger 3 has a memory function, and the rear hanger 3 can be conveniently adjusted to adapt to users with different head sizes. Specifically, the memory alloy is a memory steel wire. The inner diameter of the elastic tube 31 is larger than the outer diameter of the memory framework 32, so that the elastic tube also has the function of facilitating the conduction of a lead wire of the rear hanger 3 made of a traditional metal shell.
