The invention discloses a
bone conduction earphone, and relates to the technical field of
bone conduction, an earphone head of the
bone conduction earphone comprises a first shell
assembly, a first key
assembly, a first circuit board and a first outer end plate, the first key
assembly comprises a first key, and the first outer end plate covers a first back plate and is provided with a limiting hole for the first key to penetrate out. The first key is arranged in the first outer end plate in a penetrating manner, and the exposed area and volume of the first key are small, so that the position correspondence of the first key and the first switch is better, the first switch can be triggered more reliably when the first key is pressed, the
resonance frequency of the first key is higher, the displacement during
resonance is smaller, and the reliability of the switch is improved. And
noise generated by collision with external objects is not easy to occur. In addition, the first key is limited through the limiting hole, the radial shaking amplitude of the first key is reduced, and
noise generated by
impact is further reduced.
