Abstract

See full text

A bone conduction loudspeaker is disclosed. The loudspeaker includes a conductive case, a sound control plate arranged at one end of the conductive case and contacting with the conductive case, and an accommodating space surrounded by the conductive case and the sound control plate. The accommodating space accommodates a coil for generating a magnetic field and a magnetic assembly. The magnetic assembly, the conductive case and the sound control plate form a magnetic circuit, and the conductive case and the sound control plate are respectively made of electroacoustic materials with different thicknesses. The magnetic assembly, the conductive case and the sound control plate form a magnetic loop to form a magnetic system, and after the coil is electrified, an alternating magnetic field is generated, the alternating magnetic field intensity of the magnetic system is changed.
