CPC H04R 1/345 (2013.01) [H04R 1/1008 (2013.01); H04R 1/1075 (2013.01); H04R 1/24 (2013.01); H04R 19/02 (2013.01); H04R 2201/003 (2013.01)] | 30 Claims |
1. A speaker system, comprising:
a first acoustic transducer, configured to generate a first acoustic wave;
a second acoustic transducer, configured to generate a second acoustic wave; and
a spreading structure, comprising a body and a cover disposed on the body, wherein the body comprises an outer expanding structure, and an outer channel is formed between the cover and the outer expanding structure;
wherein the spreading structure is disposed over the first acoustic transducer and configured to guide the first acoustic wave to propagate through a sound passage formed within the spreading structure;
wherein a directionality of the first acoustic wave is spread at a sound outlet of the spreading structure after the first acoustic wave propagates through the sound passage in the spreading structure.
|
20. A spreading structure, disposed or to be disposed within a speaker system, the spreading structure comprising:
a body comprising an outer expanding structure; and
a cover disposed on the body;
wherein the spreading structure is disposed or to be disposed over a first acoustic transducer of the speaker system;
wherein the spreading structure is configured to guide a first acoustic wave generated by the first acoustic transducer to propagate through a sound passage formed within the spreading structure;
wherein an outer channel is formed between the cover and the outer expanding structure;
wherein the outer expanding structure comprises a sidewall portion;
wherein the sidewall portion has a shape such that a size of the outer channel is gradually wider from a bottom of the outer expanding structure toward a sound outlet of the spreading structure.
|
21. The spreading structure of claim 20, wherein a directionality of the first acoustic wave is spread at the sound outlet of the spreading structure after the first acoustic wave propagates through the sound passage in the spreading structure.
|
27. A speaker system, comprising:
a first acoustic transducer, configured to generate a first acoustic wave;
a second acoustic transducer, configured to generate a second acoustic wave;
a spreading structure, comprising a body and a cover disposed on the body; and
a sound spreading plate, comprising the body;
wherein the spreading structure is disposed over the first acoustic transducer and configured to guide the first acoustic wave to propagate through a sound passage formed within the spreading structure;
wherein a directionality of the first acoustic wave is spread at a sound outlet of the spreading structure after the first acoustic wave propagates through the sound passage in the spreading structure;
wherein the sound spreading plate further comprises at least one hollow part, and the second acoustic wave passes through the at least one hollow part.
|
28. A speaker system, comprising:
a first acoustic transducer, configured to generate a first acoustic wave;
a second acoustic transducer, configured to generate a second acoustic wave; and
a spreading structure;
wherein the spreading structure is disposed over the first acoustic transducer and configured to guide the first acoustic wave to propagate through a sound passage formed within the spreading structure;
wherein a directionality of the first acoustic wave is spread at a sound outlet of the spreading structure after the first acoustic wave propagates through the sound passage in the spreading structure;
wherein the sound passage is N-shaped in a cross-sectional view.
