FIELD: acoustic equipment.
SUBSTANCE: magnetic circuit assembly may generate the first magnetic field. The magnetic circuit assembly may include the first magnetic element, and the first magnetic element may generate the second magnetic field. The magnetic circuit contains two elements guiding the magnetic flux. The said at least one second magnetic element may be configured to surround the first magnetic element, and a magnetic gap may be formed between the second magnetic element and the first magnetic element. The strength of the first magnetic field in the magnetic gap may exceed the strength of the second magnetic field in the magnetic gap. The internal angle between the direction of magnetization of the said at least one second magnetic element and the direction of magnetization of the first magnetic element is in the range of 45 degrees to 135 degrees or in the range of 45 degrees to 90 degrees.
EFFECT: increased output power level of sound signals.
