All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a speaker box 100, where the speaker box 100 includes an upper shell 1, a lower shell 2 and a speaker unit 3, the upper shell 1 and the lower shell 2 cooperate to form an accommodating space, the speaker unit 3 is accommodated in the accommodating space, the speaker unit 3 includes a vibrating diaphragm 31, and the vibrating diaphragm 31 and the upper shell 1 are arranged at an interval to form a front acoustic cavity 4. The loudspeaker enclosure 100 further comprises a sound outlet channel 5 formed in the upper housing 1 and communicating the front sound cavity 4 with the outside.
The upper shell 1 is used for bearing and protecting the speaker unit 3, and includes a top wall 11 disposed opposite to the diaphragm 31 at an interval, a side wall 12 extending from a periphery of the top wall 11 to a direction close to the diaphragm 31, and an extension wall 13 extending from the side wall 12 to a direction away from the diaphragm 31, where the extension wall 13 is disposed at an interval from the top wall 11, and the speaker unit 3 is borne on the extension wall 13. The sound outlet channel 5 is enclosed by an extension wall 13 cooperating with the top wall 11 and the side wall 12.
The lower shell 2 is covered on the side wall 12 and matched with the upper shell 1 to form the accommodating space, and the loudspeaker monomer 3 is clamped between the lower shell 2 and the upper shell 1. The diaphragm 31 is used for vibrating and sounding. The front acoustic cavity 4 and the sound outlet channel 5 together form a front cavity of the loudspeaker box 100, and the diaphragm 31 cooperates with the upper shell 1 and the lower shell 2 to form a rear cavity 6.
One of the upper shell 1 and the lower shell 2 is provided with a protrusion 10, the other one is provided with a groove 20 matched with the protrusion 10, the protrusion 10 is correspondingly accommodated in the groove 20, a gap 30 is formed between the protrusion 10 and the groove wall of the groove 20 at an interval, and glue is contained in the gap 30. It will be appreciated that the gap 30 is part of the recess 20.
Specifically, in the present embodiment, the protrusion 10 is formed in the lower case 2 protruding toward the upper case 1, and the groove 20 is formed in the upper case 1 recessed toward the direction away from the lower case 2.
