Specific implementation mode
Below in conjunction with drawings and embodiments, the invention will be further described.
Please join simultaneously shown in Fig. 1-3, the present invention provides a kind of loudspeaker enclosure 100, including protecgulum 1, rear cover 2, sounding monomer
3, sound channel 4 and sealant 5 are led.
The rear cover 2 is covered on the protecgulum 1 and surrounds receiving space 10 jointly.The protecgulum 1 and the rear cover 2 can be
Integral structure or separate structure.
Specifically, the protecgulum 1 include body part 11, through the body part 11 through-hole 12 and be placed on completely described logical
Hole 12 and the steel disc 13 for being fixed on the body part 11.
The receiving of sounding monomer 3 is fixed in the receiving space 10.The sounding monomer 3 is by the receiving space 10
The operatic tunes 6 and back cavity 101 before being separated into.
That is, the sounding monomer 3 is arranged with the interval of the protecgulum 1 and surrounds the preceding operatic tunes 6 jointly；The hair
Sound monomer 3 surrounds the back cavity 101 jointly with the protecgulum 1 and the rear cover 2.
The sound channel 4 of leading is formed in the receiving space 10.Specifically, it is described lead sound channel 4 be formed in it is described before
Lid 1 can be an integral molding structure with the protecgulum 1.
Ante-chamber 102 is collectively formed with the preceding operatic tunes 6 in the sound channel 4 of leading, and the preceding operatic tunes 6 is in communication with the outside.
The through-hole 12 is connected to the ante-chamber 102.That is, in present embodiment, the steel disc 13 is at least partly
