Claims32
An apparatus comprising:
- a vibration member;
- a supporting member on a rear surface of the vibration member and including at least one first contact hole;
- a first vibration apparatus connected with the rear surface of the vibration member and between the supporting member and the vibration member, the first vibration apparatus configured to vibrate such that the vibration member vibrates;
- a second vibration apparatus between the first vibration apparatus and the supporting member, the second vibration apparatus overlapping the first vibration apparatus and including at least one second contact hole that overlaps the at least one first contact hole, and the second vibration apparatus configured to vibrate such that the vibration member vibrates;
- a control board at a rear surface of the second vibration apparatus and configured to control a vibration of the first vibration apparatus and a vibration of the second vibration apparatus;
- and
- a signal connection member including a portion disposed in the at least one first contact hole and another portion disposed in the at least one second contact hole,
- wherein the first vibration apparatus is connected with the control board via the signal connection member passing through the at least one first contact hole and the at least one second contact hole.
