Patent ID: 10126819

Abstract:
A vibration generating device has a vibration generating member that causes vibration in a vibration direction, a vibration transmitting member, and a base body. The vibration generating member has a first yoke and a second yoke spaced in the vibration direction so as to face each other, a coil that generates magnetism, and a support body that supports the first yoke. A first gap is formed between the first vibration-side opposite surface of the first yoke and the second vibration-side opposite surface of the second yoke; these surfaces face each other in the vibration direction. A second gap is formed between the first orthogonal-side opposite surface of the first yoke and the second orthogonal-side opposite surface of the second yoke; these surfaces face each other in an orthogonal direction orthogonal to the vibration direction. The first gap is narrower than the second gap.
