[specific embodiment]

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work All other embodiment obtained, fall within the protection scope of the utility model.

Please refer to Fig. 1-2, the utility model provides a kind of loudspeaker enclosure 100 comprising shell 1, sounding monomer 2, Cover board 3.

Incorporated by reference to ginseng Fig. 2-4, the shell 1 has accommodating space 10, and the shell 1 can be structure as a whole, or Separate structure, for example, the shell 1 includes upper cover 11 and is covered on the upper cover 11 and surrounds institute jointly in present embodiment State the lower cover 12 of accommodating space 10.

The shell 1 is equipped with through opening 110 thereon and is recessed the container formed by the outside of the shell 1 111, the receiving grooved ring 111 is connected to around 110 setting of opening and with the opening 110, and institute is fixed in the support of cover board 3 It states in container 111 and is covered on the opening 110 completely.The sounding monomer 2 is contained in the accommodating space 10, described Sounding monomer 2 includes the vibrating diaphragm 21 for vibration sounding, before the vibrating diaphragm 21 is surrounded with the shell 1 interval the operatic tunes 1011 and after Chamber 102.

In present embodiment, for the opening 110 through being arranged in the upper cover 11, the cover board 3 is covered on institute completely Opening 110 is stated, the preceding operatic tunes 1011 is formed between the vibrating diaphragm 21 and the cover board 3；The vibrating diaphragm 21 and the upper cover 11 and the lower cover 12 surround the back cavity 102 jointly.The back cavity 102 is used to improve the all-bottom sound of the loudspeaker enclosure 100 Learn performance.

The shell 1 include be formed in the accommodating space 10 lead sound channel 1012.It is described to lead sound in present embodiment Channel 1012 is formed in the upper cover 11, and the opening 110 is opened in the upper cover 11.The sound channel 1012 of leading will be described The preceding operatic tunes 1011 is in communication with the outside and surrounds ante-chamber 101 jointly with the preceding operatic tunes 1011.It is described lead sound channel 1012 for will The ante-chamber 101 forms side vocal structure.

The shell 1 further includes multiple extended from the inner sidewall of the opening 110 to the direction close to the cover board 3 Wall 1111 is supportted, the end face close to the cover board 3 of the supporting walls 1111 extends beyond the slot bottom of the container 111 and supports It is connected to the cover board 3；The cover board 3 is fixed on the container 111, the container 111, the supporting walls by glue 1111 and the cover board 3 surround the clearance space 1110 for accommodating glue altogether.It is extra that the clearance space 1110 can accommodate The glue of spilling prevents glue from overflowing to opening to sounding unit, so as to improve the acoustical behavior of the loudspeaker enclosure 100.

In present embodiment, the cover board 3 is squeezed to the upper cover 11, is come, is avoided so that glue is evenly distributed The phenomenon that spilling of glue, so that adhesion effect is good, to avoid the cover board 3 from generating noise because of shell shake, before raising is described The operatic tunes 101, so that the acoustical behavior of the loudspeaker enclosure 100 is excellent；In addition, also improve the cover board 3 with it is described on The glued reliability of lid 11 avoids the cover board 3 from falling off from the upper cover 11 due to shell shake, so that the loudspeaker enclosure High reliablity.

Specifically, the width of the supporting walls 1111 is d1, the end face close to the cover board 3 of the supporting walls 1111 To the distance of the slot bottom of the container 111, the distance is the slot bottom that the supporting walls 1111 exceed the container 111 Height d2, it is preferred that the width d1 is preferably 0.2mm, and the distance is preferably that (the i.e. described height d2 is preferably 0.03mm 0.03mm)；The glue with a thickness of d3 can be retained in the clearance space 1110, it is preferred that the thickness d 3 is preferably 0.05mm.It is noted that the thickness d 3 by the supporting walls 1111 the width d1 and the height d2 size It is determined, therefore can be according to the requirement of 100 Optimal Structure Designing of loudspeaker enclosure, it can be by adjusting the supporting walls 1111 size retains the thickness of glue so as to adjust the clearance space 1110, so that the cover board 3 and the upper cover 11 Glued reliability is higher, so that 100 reliability of the loudspeaker enclosure is higher.

Preferably, the supporting walls 1111 include at least four and are mutually arranged at equal intervals, so that the cover board 3 more may be used By be glued on the shell 1 so that 100 reliability of the loudspeaker enclosure is higher.

Certainly, four supporting walls 1111, which can also be abutted mutually, is arranged and surrounds wall structure jointly.The support The structure and size of wall 1111 are not limited to this.

Specifically, the cover board 3 is made of metal material, it is preferably steel disc in present embodiment, so that the loudspeaker The high-frequency acoustic performance of case 100 is excellent, so that the acoustical behavior of the loudspeaker enclosure 100 is excellent, the material of certain cover board 3 It is without being limited thereto.

Compared with the relevant technologies, it is provided in the shell 1 by the shell 1 in the loudspeaker enclosure 100 of the utility model Outside be recessed the container 111 to be formed and from it is described opening 110 inner sidewall to close to the cover board 3 direction extend it is more A supporting walls 1111, the end face close to the cover board 3 of the supporting walls 1111 extend beyond the slot bottom of the container 111 And it is connected to the cover board 3；The cover board 3 is fixed on the container 111, the container 111, the support by glue Wall 1111 and the cover board 3 surround the clearance space 1110 for accommodating glue altogether, and the clearance space 1110 is for retaining one The glue for determining thickness, the case where avoiding excessive glue in gluing procedures, so that the gluing of the cover board 3 and the container 111 Reliably, good airproof performance, so that the acoustical behavior of the loudspeaker enclosure 100 is excellent and high reliablity.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other relevant technical fields, are also included in the patent protection scope of the utility model.
