Claims (2)

1. Электромагнитно-акустический преобразователь, содержащий корпус с размещенными в нем постоянным магнитом, и двумя расположенными в одной плоскости и смещенными друг относительно друга взаимодействующими с магнитом высокочастотными катушками индуктивности, выполненными из проводов разного диаметра, одна из которых является излучающей, а другая служит для приема акустических колебаний под углами, отличающийся тем, что каждая высокочастотная катушка образована восемью размещенными на расстоянии друг от друга встречновключенными обмотками, причем каждая последующая обмотка, расположенная от периферии к центру, по отношению к предыдущей содержит большее число витков.1. An electromagnetic-acoustic transducer comprising a housing with a permanent magnet placed in it, and two high-frequency inductors interacting with the magnet located in the same plane and offset from one another, made of wires of different diameters, one of which is emitting, and the other serves to receiving acoustic vibrations at angles, characterized in that each high-frequency coil is formed by eight on-off opposed coils, and each subsequent winding, located from the periphery to the center, in relation to the previous one contains a larger number of turns. 2. Электромагнитно-акустический преобразователь по п.1, отличающийся тем, что он выполнен с возможностью возбуждения импульсными сигналами с различной частотой заполнения, при котором генерируются акустические сигналы, максимумы которых соответствуют углам 35 и 60-65°, с минимальным излучением под другими углами.2. The electromagnetic acoustic transducer according to claim 1, characterized in that it is configured to excite by pulsed signals with different filling frequencies, at which acoustic signals are generated, the maximums of which correspond to angles of 35 and 60-65 °, with minimal radiation at other angles .
