Wherein, the end of described fixed part is provided with the segmental arc of bending downwards.
Wherein, described sealing sheet is metal or nonmetallic slices.
Wherein, described sealing sheet is steel disc, potsherd, glass fiber sheets or hard plastic sheet.
Wherein, the position of the corresponding described loudspeaker monomer in the upside of described shell is provided with installing hole, solid at described installing hole
Surely there is steel disc.
Wherein, described speaker module is set of half mould sets structure.
After have employed technique scheme, the beneficial effects of the utility model are:
Owing to, on the shell going out the sidepiece that acoustic aperture is arranged in loudspeaker monomer of this utility model speaker module, going out
Acoustic aperture is fixed with the sealing sheet of high intensity on the shell of loudspeaker monomer one end, and one end of sealing sheet is held within
Going out on the shell below acoustic aperture, the other end is overlapped on the upper surface of loudspeaker monomer.Sealing sheet makes on loudspeaker monomer
The surrounding of end all have can the parts (going out at acoustic aperture is sealing sheet, and other position is shell) of adhesive bond, thus speaker list
The edge of the whole upper surface of body all can seal with gluing, is greatly improved the sealing property of the operatic tunes before module, it is possible to
Meet the requirement of the special seals such as fire resistance characteristic；Simultaneously sealing sheet also to loudspeaker monomer in Z-direction (short transverse)
Serve the effect of location, add the positioning intensity of loudspeaker monomer Z axis；And owing to sealing sheet is by the material system of high intensity
Become, i.e. sealing sheet only needs the least thickness can meet requirement of strength, therefore takes up room less, will not block and speak
Hole, ensure that out the unimpeded of acoustic aperture while improving sealing property, it is ensured that the sound quality of speaker module, improves and raise
The overall performance of sound device module.
Owing to the end of the fixed part of sealing sheet is provided with the segmental arc of bending downwards, at sealing sheet with shell by note
Moulding technique when combining, the segmental arc of bending can effectively increase the contact surface between sealing sheet and shell injection molding material downwards
Long-pending, thus enhance the bond strength between sealing sheet and shell, decrease the risk that sealing sheet comes off from shell, carry
The reliability of high speaker module and service life.
In sum, this utility model speaker module solves the skill such as speaker module poor sealing performance in prior art
Art problem, this utility model speaker module is while meeting special seal performance requirement, to the loss of acoustical behavior
Little, it is ensured that the sound quality of speaker module, overall performance is high.
