Abstract
A flat panel speaker according to an embodiment of the disclosure includes a flat panel and a plurality of vibrators that are disposed on a back surface of the flat panel. The plurality of vibrators are disposed to avoid a location that most easily vibrates in an entire range of audio frequencies when vibration is generated in the flat panel by the plurality of vibrators. A large stationary wave with respect to the flat panel therefore does not easily occur.
Claims18
A flat panel speaker comprising:
- a flat panel;
- and
- a plurality of vibrators that are disposed on a back surface of the flat panel and cause the flat panel to vibrate, the plurality of vibrators being disposed at locations having a lateral coordinate along a lateral direction and a vertical coordinate along a vertical direction of the flat panel;
- and
- a vibration controlling member fixed to the back surface of the flat panel and that partitions the back surface of the flat panel into a first closed partition region including a first vibration point and a second closed partition region including a second vibration point,
- the vibration controlling member includes a first vibration controlling member that forms the first closed partition region and a second vibration controlling member that forms the second closed partition region, wherein the first closed partition region and the second closed partition region are positioned vertically symmetrical relative to a vertical central axis extending along the vertical direction or the first closed partition region and the second closed partition region are positioned laterally symmetrical relative to a lateral central axis extending along the lateral direction.

A flat panel speaker comprising:
- a flat panel;
- a vibrator that is disposed on a back surface of the flat panel and causes the flat panel to vibrate, the vibrator being disposed at a location having a lateral coordinate along a lateral direction and a vertical coordinate along a vertical direction of the flat panel;
- and
- a vibration controlling member fixed to the back surface of the flat panel and that partitions the back surface of the flat panel into a first closed partition region including a first vibration point and a second closed partition region including a second vibration point,
- the vibration controlling member includes a first vibration controlling member that forms the first closed partition region and a second vibration controlling member that forms the second closed partition region, wherein the first closed partition region and the second closed partition region are positioned vertically symmetrical relative to a vertical central axis extending along the vertical direction or the first closed partition region and the second closed partition region are positioned laterally symmetrical relative to a lateral central axis extending along the lateral direction.

A display unit comprising:
- a display cell that is shaped like a thin plate and displays an image;
- a plurality of vibrators that are disposed on a back surface of the display cell and cause the display cell to vibrate, the plurality of vibrators are disposed at locations having a lateral coordinate along a lateral direction and a vertical coordinate along a vertical direction of the flat panel such that the ratio of the lateral coordinate and the vertical coordinate is indivisible;
- and
- a vibration controlling member that is fixed to the back surface of the flat panel and that partitions the back surface of the flat panel into a first closed partition region including a first vibration point and a second closed partition region including a second vibration point,
- the vibration controlling member includes a first vibration controlling member that forms the first closed partition region and a second vibration controlling member that forms the second closed partition region, wherein the first closed partition region and the second closed partition region are positioned vertically symmetrical relative to a vertical central axis extending along the vertical direction or the first closed partition region and the second closed partition region are positioned laterally symmetrical relative to a lateral central axis extending along the lateral direction.

A display unit comprising:
- a display cell that is shaped like a thin plate and displays an image;
- a vibrator that is disposed on a back surface of the display cell and causes the display cell to vibrate, the vibrator being disposed at a location having a lateral coordinate along a lateral direction and a vertical coordinate along a vertical direction of the flat panel such that the ratio of the lateral coordinate and the vertical coordinate is indivisible;
- and
- a vibration controlling member that is fixed to the back surface of the flat panel and that partitions the back surface of the flat panel into a first closed partition region including a first vibration point and a second closed partition region including a second vibration point,
- the vibration controlling member includes a first vibration controlling member that forms the first closed partition region and a second vibration controlling member that forms the second closed partition region, wherein the first closed partition region and the second closed partition region are positioned vertically symmetrical relative to a vertical central axis extending along the vertical direction or the first closed partition region and the second closed partition region are positioned laterally symmetrical relative to a lateral central axis extending along the lateral direction.
