Accommodating space 5 is separated into ante-chamber 51 and back cavity 52 by sound monomer 2, and roof 32, supporting walls 33 and sounding monomer 2 surround before being formed
Chamber 51, back cavity 52 can be used for improving the acoustical behavior of the loudspeaker enclosure.
In above-described embodiment, as shown in Figures 2 and 3,3 side of lower cover offers the sound outlet hole 31 being connected to ante-chamber 51, under
Lid 3 further includes the wall 34 extended in back cavity 52 from roof 32 to 1 direction of upper cover, which further includes that lid is located at wall
34 seal assemblies 4 far from 32 one end of roof, wall 34 are connect with supporting walls 33, wall 34, supporting walls 33 and seal assembly 4
It surrounds to form resonant cavity 53, supporting walls 33 offer via hole 335, and resonant cavity 53 is connected to through via hole 335 with ante-chamber 51.
Connect specifically, via hole 335 and 31 face of sound outlet hole, resonant cavity 53 and ante-chamber 51 are only realized by via hole 335
It is logical, the cavity volume of ante-chamber 51 can not only be effectively increased, improves high-frequency acoustic performance, reduces the high-frequency resonance peak of loudspeaker enclosure
Q value (quality factor value) and sensitivity so that the acoustical behavior of loudspeaker enclosure is more excellent, and the structure design of wall 34 can also
With more various, the expansion scope of application.In addition, resonant cavity 53 is not take up the height space of loudspeaker enclosure, so that loudspeaker enclosure is whole
Body is realized lightening.In other embodiments, resonant cavity 53 also can be set sounding monomer 2 not with 31 face of sound outlet hole
In addition two sides, the present embodiment are not limited in this respect, and are connected to as long as can be realized resonant cavity 53 with ante-chamber 51.
In above-described embodiment, as shown in figure 5, supporting walls 33 include towards the upper surface of upper cover 1 331 and from upper surface
331 two sides extend respectively to the inner wall 332 and outside wall surface 334 of roof 32, and inner wall 332 is located at supporting walls 33 close to ante-chamber 51
Side, outside wall surface 334 is located at supporting walls 33 close to the side of back cavity 52, and upper surface 331 is recessed to form towards 32 direction of roof
One groove 333, the first groove 333 extend to inner wall 332, and the first groove 333 is circumferentially arranged along the inner ring of supporting walls 33, sounding
Monomer 2 is fixed on the first groove 333, so that the fixation of sounding monomer 2 is stronger, improves the stabilization of loudspeaker enclosure sounding
Property.
In addition, as shown in Figure 4 and Figure 5, wall 34 includes close towards the upper surface of upper cover 1 341 and from upper surface 341
