Vibration structure, conveyance device, and tactile sense presentation device

A vibration structure comprising:

• a fixing member;
• a voltage expansion/contraction member configured to be deformed in a first direction by a voltage;
• a first vibration member that is elastically coupled to the fixing member and configured to vibrate in the first direction with respect to the fixing member;
• and
• a second vibration member that is elastically coupled to the first vibration member and configured to vibrate in the first direction with respect to the first vibration member,
• wherein the voltage expansion/contraction member is supported by the fixing member and at least one of the first vibration member and the second vibration member,
• wherein a vibration of the first vibration member is superposition of a first vibration at a first resonance frequency and a second vibration at a second resonance frequency, and a vibration of the second vibration member is superposition of the first vibration and the second vibration, and
• wherein the second resonance frequency is an integral multiple of the first resonance frequency.
