Referring to fig. 1-3, the present invention provides a speaker box 100, which includes a front cover 1, a rear cover 2, a sound generating unit 3, a sound guiding channel 4 and a sealing layer 5.
The rear cover 2 covers the front cover 1 and jointly forms an accommodating space 10. The front cover 1 and the rear cover 2 can be of an integral structure or a split structure.
Specifically, the front cover 1 includes a main body 11, a through hole 12 penetrating the main body 11, and a steel sheet 13 completely covering the through hole 12 and fixed to the main body 11.
The sound generating unit 3 is accommodated and fixed in the accommodating space 10. The sound generating unit 3 divides the accommodating space 10 into a front sound cavity 6 and a rear cavity 101.
That is, the sound generating unit 3 and the front cover 1 are arranged at intervals and jointly enclose the front sound cavity 6; the sounding monomer 3, the front cover 1 and the rear cover 2 jointly enclose the rear cavity 101.
The sound guiding channel 4 is formed in the receiving space 10. Specifically, the sound guide channel 4 is formed in the front cover 1, and may be an integrally formed structure with the front cover 1.
The sound guide channel 4 and the front sound cavity 6 together form a front cavity 102, and the front sound cavity 6 is communicated with the outside.
The through hole 12 communicates with the front chamber 102. That is, in the present embodiment, the steel sheet 13 is at least partially disposed opposite to the front cavity 102. The steel sheet 13 is used for reducing acoustic performance such as harmonic spike distortion of the loudspeaker enclosure 100,
preferably, the steel sheet 13 is arranged right opposite to the sounding monomer 3, and the harmonic distortion effect of the changed cover is more obvious.
The sealing layer 5 is fixedly arranged on the steel sheet 13, and the sealing layer 5 is at least arranged on the periphery of the steel sheet 13 in a surrounding manner and is clamped between the body part 11 and the steel sheet 13. The structure enables the sealing layer 5 to play a role in sealing between the steel sheet 13 and the body part 11 on one hand, and play a role in bonding on the other hand, so that the gap between the body part 11 and the steel sheet 13 is reduced, the front cover 1 has high structural consistency and high stability, the sealing performance of the front cover 1 is improved, and the appearance aesthetic feeling is not influenced.
