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.
