Example, is further elaborated to the utility model.It should be appreciated that specific embodiment described herein is only used to explain
The utility model, and it is not used in restriction the utility model.
Reference picture 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the loudspeaker module of the present embodiment, including module shell and it is housed in
Loudspeaker monomer 4 in module shell, the module inner chamber that loudspeaker monomer 4 surrounds module shell is divided into the preceding operatic tunes 5 with after
6 two cavitys of the operatic tunes, are provided with the dividing plate 21 for the preceding operatic tunes 5 to be separated with the rear operatic tunes 6 in module inner chamber, dividing plate 21 is provided with to be let out
Pressure device, pressure relief device includes the pressure release passage 7 of the preceding operatic tunes 5 of connection and the rear operatic tunes 6 and acoustic seal, and pressure release passage 7 includes opening
Through hole 71 on dividing plate 21, the position on dividing plate 21 positioned at through hole 71 is provided with boss 8, just right on the surface of boss 8
The hollow hole 73 of insertion is offered at through hole 71, the periphery edge of hollow hole 73 is located at the open circumferential edge of through hole 71
Outside, a certain distance is left between both peripheries；Gas pressure relief slot 72 is offered on the surface of boss 8, its top connection hollow out
Hole 73, end extends to the termination of boss 8.
Reference picture 5, present embodiment illustrates a kind of circular hollow hole 73, hollow hole it is straight with diameter greater than through hole
Footpath.Certainly, hollow hole 73 may also take on square or other shapes.
In the present embodiment, module shell includes the upper casing 1, middle shell 2 and the lower casing 3 that snap together, during dividing plate 21 is arranged on
On shell 2.Module inner chamber is divided into the preceding operatic tunes 5 and the rear operatic tunes 6 by loudspeaker monomer 4 together with dividing plate 21.
Loudspeaker module of the present utility model, the pressure release passage 7 is acoustic seal, is come for those skilled in the art
Say, the implication of acoustic seal is acoustically to be in the state of acoustic seal, that is to say, that do not allow sound wave to pass through.The pressure release is led to
Road 7 is acoustic seal, that is to say, that the sound in the preceding operatic tunes 5 does not pass through the pressure release passage 7 and enters in the rear operatic tunes 6,
The isolation of the preceding operatic tunes 5 and the rear operatic tunes 6 is thereby may be ensured that, to prevent loudspeaker from failing.
The acoustic seal of the pressure release passage 7 can be realized by means well-known to those skilled in the art, for example should
Pressure release passage 7 is made thin small, or by other well known means, improves the damping of the pressure release passage 7, becomes damping knot
Structure, such that it is able to prevent sound from being propagated in the pressure release passage 7.
