Abstract

The present disclosure relates to a magnetic circuit assembly of a bone conduction speaker. The magnetic circuit assembly may generate a first magnetic field. The magnetic circuit assembly may include a first magnetic element, and the first magnetic element may generate a second magnetic field. The magnetic circuit may further include a first magnetic guide element and at least one second magnetic element. The at least one second magnetic element may be configured to surround the first magnetic element and a magnetic gap may be configured between the second magnetic element and the first magnetic element. A magnetic field strength of the first magnetic field within the magnetic gap may exceed a magnetic field strength of the second magnetic field within the magnetic gap.
