Abstract
A speaker includes a speaker enclosure and at least one speaker driver. The speaker enclosure includes an upper housing and a lower housing matched with the upper housing. A bottom face of the upper housing is recessed upward to form a first chamber. The upper housing defines at least one first opening communicating with the first chamber. The speaker driver is fitted in the first opening hermetically. A top face of the lower housing is recessed downward to form a second chamber. The second chamber is interconnected with the first chamber to form an inner chamber in the speaker enclosure. An adjusting assembly is disposed in the second chamber of the lower housing. The adjusting assembly is used to adjust the air volume in the inner chamber by selectively installing a different dimension of the adjusting assembly or a different number of the adjusting assembly.
