## Abstract

The present invention discloses a multifunctional bone conduction earphone, including a left earphone body, a right earphone body and speaker position adjustment mechanisms. The left earphone body includes a left ear hanger body; the right earphone body includes a right ear hanger body; and the speaker position adjustment mechanisms are arranged on the ear hanging bodies and used for adjusting positions of speaker bodies. In a relatively noisy environment, the speaker position adjustment mechanisms are adjusted, so that the speaker bodies cover ears, thereby playing a role of shielding external sounds and avoiding interference from the external sounds.

## Claims

### Claim 1

A multifunctional bone conduction earphone, comprising:
a left earphone body, comprising a left speaker body and a left ear hanger body, wherein one end of the left ear hanger body is fixedly connected with the left speaker body;
a right earphone body, comprising a right speaker body and a right ear hanger body, wherein one end of the right ear hanger body is fixedly connected with the right speaker body; and
a left damping adjustment mechanism arranged on the left ear hanger body, wherein the left damping adjustment mechanism is used for adjusting a position of the left speaker body; and
the left ear hanger body comprises a first left ear hanger body and a second left ear hanger body;
the left damping adjustment mechanism comprises a left damping rotating shaft; in the first left ear hanger body and the second left ear hanger body, at least the first left ear hanger body is rotatably and fixedly connected with the left damping rotating shaft; and one end of the first left ear hanger body away from the left damping rotating shaft is fixedly connected with the left speaker body, and
the left damping adjustment mechanism further comprises a first left rotating rod and a second left rotating rod; the first left ear hanger body is rotatably and fixedly connected with the left damping rotating shaft through the first left rotating rod; and the second left ear hanger body is fixedly connected with the left damping rotating shaft through the second left rotating rod.

### Claim 2 (depends on 1)

The multifunctional bone conduction earphone according to claim 1, wherein a first control groove is formed in the first left rotating rod; a first control part is fixedly arranged on the second left rotating rod; one end of the first control part extends into the first control groove; and the first control part and the first control groove are used for controlling a rotation angle of the first left rotating rod relative to the second left rotating rod.

### Claim 3 (depends on 1)

The multifunctional bone conduction earphone according to claim 1, wherein the rotation angle of the first left rotating rod relative to the second left rotating rod is not greater than 60 degrees; a force required for pushing the first left rotating rod to rotate relative to the second left rotating rod is not greater than 15N; an acting point of the pushing force is located on the left speaker body; the pushing force is perpendicular to the left damping rotating shaft; and the pushing force is perpendicular to a connecting line between the acting point and a center of the left damping rotating shaft.
