Vibration device, a bone conduction headphone, and an intelligent hardware device

Abstract

The invention discloses a vibration device, a bone conduction headphone, and an intelligent hardware device, which belong to the field of vibration technology. The vibration device comprises: a case; an electromagnetic driving part including a coil connected to the case; and a vibrator, including a magnetic part movably arranged in the coil and an elastic part connected between the magnetic part and the case; the magnetic part includes at least two magnet portions and a non-magnetic portion located between two adjacent magnet portions. In the present invention, the magnetic part is made of magnetic material integrally magnetized. Compared with the original structure that requires multiple magnets to be connected, it has fewer parts, and is more convenient to install, while also achieving higher dimensional accuracy, thereby improving the assembly accuracy with the coil.
