FIELD: acoustics.
SUBSTANCE: invention relates to acoustics, in particular, to dynamic loudspeakers. The unit of the magnetic circuit of the bone conduction reproducer comprises a first magnetic element generating a second magnetic field; a first magnetic guiding element and at least one second magnetic element configured to surround the first magnetic element, wherein a magnetic gap is provided between said at least one second magnetic element and the first magnetic element, wherein the intensity of the first magnetic field in the magnetic gap exceeds the intensity of the second magnetic field in the magnetic gap, a second magnetic guiding element and at least one third magnetic element connected with the second magnetic guiding element and said at least one second magnetic element, wherein the internal angle between the direction of magnetisation of said at least one third magnetic element and the direction of magnetisation of the first magnetic element is in the range from 45 degrees to 135 degrees or in the range from 90 degrees to 135 degrees.
EFFECT: increase in the emitted power of sound.
