PROBLEM TO BE SOLVED: To provide a low-frequency sound oscillation transducer technique which is immune to shock. SOLUTION: In the low-frequency sound oscillation transducer in which metal plates are stuck onto the front and the back of a ferrite to be moved by the swinging and which oscillates a sonic wave of a low-frequency sound band, shock absorbers are disposed respectively between each surface of the front and the back, and a container.
