Abstract
A vibration apparatus may include a vibration generating part including at least one or more vibration parts. The vibration apparatus may further include a first cover member at a first surface of the vibration generating part, a second cover member at a second surface of the vibration generating part, and a signal cable including first and second signal lines connected to the at least one or more vibration parts. The second surface of the vibration generating part is different from the first surface of the vibration generating part. The first and second signal lines may be provided between the second cover member and the vibration generating part.
