Abstract

A speaker including one or multiple transducers, an enclosure, and a suspension mounted on the enclosure, wherein the suspension and the enclosure are configured such that the enclosure is capable of vibrating as a result of operation of the transducer so as to produce audible sound.

First claim

The invention claimed is:

1. A speaker comprising a transducer, an enclosure, and a suspension mounted on the enclosure, wherein the suspension and the enclosure are configured to promote vibration of the enclosure as a result of operation of the transducer so as to produce audible sound,
wherein the enclosure comprises at least a first portion and a second portion with the suspension connected therebetween,
wherein the suspension is positioned on an outer surface of the enclosure and a first axis extends through the suspension, and
wherein the transducer is positioned on the outer surface of the enclosure and a second axis extends through the transducer, the first axis being perpendicular to the second axis.

2. The speaker of claim 1 further comprising a plurality of transducers.

3. The speaker of claim 1 , wherein the suspension is made of a flexible material.

4. The speaker of claim 3 , wherein the flexible material comprises rubber, foam, Polyvinyl Chloride, or Polyurethane.

5. The speaker of claim 1 , wherein the suspension is configured as a flexible configuration of spring or corrugated paper.

6. The speaker of claim 1 , wherein a respective weight of the first portion and the second portion of the enclosure and a compliance of the suspension are selected for achievement of the vibration of the enclosure.

7. The speaker of claim 1 , wherein the enclosure comprises a side on which the transducer is mounted, the suspension being disposed on said side and surrounding the first portion of the enclosure.

8. The speaker of claim 7 , wherein the transducer is attached to the first portion of the enclosure through a through hole formed therein.

9. The speaker of claim 8 , wherein the first portion of the enclosure has a circular shape, a rectangular shape or an oval shape.

10. The speaker of claim 1 , wherein the enclosure is mounted on an elastic stand.

11. The speaker of claim 7 , wherein the transducer, the first portion of the enclosure and the suspension collectively function as a passive radiator.

12. A speaker comprising:
a transducer;
an enclosure including a first portion and a second portion that is separate from one another; and
a suspension positioned between the first portion and the second portion,
wherein the suspension and the enclosure are configured to promote vibration of the enclosure as a result of operation of the transducer to produce an audible sound,
wherein the suspension is positioned on an outer surface of the enclosure and a first axis extends through the suspension, and
wherein the transducer is positioned on the outer surface of the enclosure and a second axis extends through the transducer, the first axis being perpendicular to the second axis.

13. The speaker of claim 12 further comprising a plurality of transducers.

14. The speaker of claim 12 , wherein the suspension is made of flexible material.

15. A speaker comprising:
a transducer;
an enclosure including a first portion and a second portion, the first portion being separate from the second portion and defining a through hole therein to receive the transducer; and
a suspension connected to the first portion and to the second portion, wherein the suspension and the enclosure are configured to promote vibration of the enclosure as a result of operation of the transducer to produce an audible sound,
wherein the suspension is positioned on an outer surface of the enclosure and a first axis extends through the suspension, and
wherein the transducer is positioned on the outer surface of the enclosure and a second axis extends through the transducer, the first axis being perpendicular to the second axis.

16. The speaker of claim 15 , wherein the suspension is made of flexible material.

17. The speaker of claim 1 , wherein the first portion of the enclosure is substantially a same weight as the second portion of the enclosure.

18. The speaker of claim 12 , wherein the first portion of the enclosure is substantially a same weight as the second portion of the enclosure.

19. The speaker of claim 15 , wherein the first portion of the enclosure is substantially a same weight as the second portion of the enclosure.
