Abstract

A speaker and a method of producing a speaker, the speaker including: an enclosure; at least one transducer mounted in the enclosure; and at least one passive radiator mounted in the enclosure, including a suspension and a center panel encircled by and adhered to the suspension, wherein the at least one transducer is combined with the at least one passive radiator, and functions as at least a part of the center panel. According to the speaker of the present disclosure, by fully or partly replacing the center panel of the at least one passive radiator by one or more transducer(s), both the internal space and the cost of the speaker are saved without sacrificing the sound quality.

First claim

What is claimed is:

1. A speaker, comprising:
an enclosure;
a plurality of transducers mounted in the enclosure; and
a passive radiator mounted in the enclosure, comprising a suspension and a center panel encircled by and connected to the suspension,
wherein the plurality of transducers is combined with the passive radiator, and the plurality of transducers is encircled by the suspension of the passive radiator,
wherein the plurality of transducers fully replaces the center panel in its entirety of the passive radiator.

2. The speaker of claim 1 , wherein the plurality of transducers is mounted on the passive radiator in a way of locating within the enclosure.

3. The speaker of claim 1 , wherein the plurality of transducers is combined with the passive radiator in any way of the following: adhering, riveting, crimping, and bolting.

4. The speaker of claim 1 , wherein a shape of one of the plurality of transducers and the passive radiator is any one of the following: a disk, an ellipse, a diamond, a square, a triangle, and any irregular shape.

5. The speaker of claim 1 , further comprising at least one transducer mounted in the enclosure and separately from the passive radiator.

6. The speaker of claim 1 , wherein the plurality of transducers is combined with the passive radiator in a way of being directly connected to and encircled by the suspension.

7. The speaker of claim 1 wherein the plurality of transducers functions as at least a part of the center panel when the plurality of transducers is combined with the passive radiator.

8. A method of producing a speaker, comprising steps of:
providing an enclosure; and
mounting a plurality of transducers combined with a passive radiator in the enclosure,
wherein the passive radiator comprises a suspension and a center panel connected with and encircled by the suspension, and the plurality of transducers is encircled by the suspension of the passive radiator, and
wherein the plurality of transducers fully replaces the center panel in its entirety of the passive radiator.

9. The method of claim 8 , wherein the plurality of transducers functions as at least a part of the center panel when the plurality of transducers is combined with the passive radiator.

10. The method of claim 8 , further comprising combining the plurality of transducers with the passive radiator in any way of the following: adhering, riveting, crimping, and bolting.

11. The method of claim 8 , wherein a shape of one of the plurality of transducers and the passive radiator is any one of the following: a disk, an ellipse, a diamond, a square, a triangle, and any irregular shape.

12. The method of claim 8 , wherein the plurality of transducers is combined with the passive radiator in a way of being directly connected to and encircled by the suspension.
