Abstract
An apparatus may enhance a sound characteristic and/or a sound pressure level characteristic. An apparatus includes a vibration member, a vibration apparatus under the vibration member, a plurality of vibration portions overlapping one another, and a connection member connecting at least a portion of the plurality of vibration portions to the vibration member.
Claims32
An apparatus, comprising:
- a vibration member;
- a plurality of vibration generating portions configured to vibrate the vibration member in a vertical direction, the plurality of vibration generating portions overlapping one another in the vertical direction;
- and
- a connection member connecting at least a portion of the plurality of vibration generating portions to the vibration member,
- wherein the connection member comprises a first connection member, and at least two additional connection members spaced apart from the first connection member,
- wherein the at least two additional connection members comprise a second connection member and a third connection member, and
- wherein the second connection member and the third connection member are symmetrical to each other with the first connection member therebetween.
