Claims (1)

Электромагнитно-акустический преобразователь, содержащий магнитную систему в виде постоянного магнита и три плоские катушки, электрически изолированные друг от друга и расположенные под магнитом одна под другой, отличающийся тем, что постоянный магнит выполнен в виде сплошного цилиндра при соотношении его диаметра и высоты 1:3, а витки одной плоской катушки расположены под углом 120° к виткам другой катушки, а диаметр окружности, описывающей витки каждой катушки, равен диаметру постоянного магнита.An electromagnetic-acoustic transducer containing a magnetic system in the form of a permanent magnet and three flat coils, electrically isolated from each other and located under the magnet one under the other, characterized in that the permanent magnet is made in the form of a solid cylinder with a ratio of its diameter and height of 1: 3 and the turns of one flat coil are located at an angle of 120 ° to the turns of another coil, and the diameter of the circle describing the turns of each coil is equal to the diameter of the permanent magnet.
