Abstract

The present invention provides a vertically or horizontally placeable combinative array speaker. The vertically or horizontally placeable combinative array speaker includes a microprocessor, an orientation sensor coupled to the microprocessor to sense condition changes of the combinative array speaker, a sound field reconstructing unit formed within or outside of the combinative array speaker, wherein the sound field reconstructing unit is coupled to the microprocessor to simulate surround sounds, and array speakers coupled to the sound field reconstructing unit through an amplifier.

Claims

1. A structure of a vertically or horizontally placeable combinative array speaker, comprising:

a microprocessor;

an orientation sensor coupled to said microprocessor to sense condition changes of said combinative array speaker;

a sound field reconstructing unit formed within or outside of said combinative array speaker, wherein said sound field reconstructing unit is coupled to said microprocessor to simulate surround sounds; and

array speakers coupled to said sound field reconstructing unit through an amplifier.

2. The structure of claim 1, wherein said array speakers comprise at least a bass speaker, at least two alt speakers, and at least two passive plates.

3. The structure of claim 2, wherein said bass speaker, said alt speakers, and said passive plates are coupled with each other parallelly or serially.

4. The structure of claim 2, wherein said bass speaker, said alt speakers, and said passive plates are disposed vertically and linearly.

5. The structure of claim 2, wherein said bass speaker, said alt speakers, and said passive plates are disposed horizontally and linearly.

6. The structure of claim 1, wherein said combinative array speaker comprises a horizontally placed array speaker and at least a vertically placed array speaker.

7. The structure of claim 1, wherein said sound field reconstructing unit comprises a digital signal processor.

8. The structure of claim 1, wherein said sound field reconstructing unit further comprises a digital delay circuit.

9. The structure of claim 1, wherein said orientation sensor comprises a mercury sensor.

10. The structure of claim 1, wherein said orientation sensor comprises a gravity sensor.
