An elastic ring wall 225 of the fixing sleeve is provided between the outer ring of the microphone fixing sleeve and the soft rubber layer corresponding to the inner ring of the rear ring piece. The thickness of the elastic ring wall of the fixing sleeve is 0.4-0.7 mm, which can increase the pressure of the microphone pressing against the skin and reduce the noise conduction of other parts of the earphone. The bottom of the microphone fixing sleeve is filled with the foam support pad A to make the microphone more stable during use and reduce the generation of noise. The microphone is resting between the foam support pad A and the microphone fixing cover, and the microphone fixing cover is connected to the open end of the microphone fixing sleeve. When worn, the microphone fixing cover is pressed against the mastoid part of the temporal bone behind the ear. Both the microphone fixing sleeve and the microphone fixing cover are made of silicone.

[0037] The bone conduction speaker 23 includes a speaker fixing sleeve, a speaker 231, a foam support pad B, a speaker fixing cover and a speaker wire. The outer wall of the speaker fixing sleeve is inserted into the front ring piece, and the bottom of the speaker fixing sleeve is filled with the foam support pad B.

The Bluetooth motherboard 10A and the battery 10B of the Bluetooth headset are installed in the upper cover 11A and connected with the microphone wire and the speaker wire. The microphone wire and the speaker wire are arranged on the groove of the nickel-titanium steel sheet of the telescopic sheet. The wires before connecting with the Bluetooth motherboard are in a soft row shape to adapt to the pulling of the telescopic sheet body. The main difference from the head beam body of the previous embodiment is the upper cover and the lower cover. The upper cover 11A and the lower cover 11B of this embodiment are only adjusted for applicability based on the previous embodiment to accommodate the Bluetooth motherboard and the battery.

[0044] The earphone of the utility model fundamentally solves the problem that voice communication equipment such as walkie-talkies can be "inaudible or unclear" in a high-noise environment in a complex environment at a disaster site.

[0045] The bone conduction anti-noise hearing and listening earphones of this utility model are dual bone pickups and dual bone speakers, which solve the problem of low sound and unclear sound of most professional bone conduction earphones. Nickel-titanium alloy combined with skin-friendly soft silicone is selected, which has good rebound performance, strong toughness, not easy to deform, and comfortable to wear. The dynamic suspension design of the elastic ring wall of the fixed sleeve is suitable for the temporal bones of different head shapes, and the shock-absorbing design of the microphone fixed sleeve type installation reduces noise interference. The cross-ear clamping design of the bone pickup and bone speaker solves the problem of skin-friendly fit of the bone pickup and greatly improves the sound restoration. The pull-out design is used to adapt to different head shapes and has good adaptability.
