Abstract:
Provided is an electronic device, comprising a case body, a piezoelectric element, and a panel which is attached to the case body, disposes a contact region which makes contact with a portion of a person's body, is vibrated by the piezoelectric element, and emits a vibration sound which is transmitted by vibrating the portion of the person's body. Making pressure from within the case body in the contact region of the panel lower than pressure from within the case body in another region different from the contact region improves a sound pressure characteristic, and the electronic device of a type which vibrates the panel and emits air conduction sounds and vibration sounds operates desirably.
