Embodiment
With reference to the accompanying drawings and examples, the present invention is expanded on further.
It is jointly shown with Fig. 3 as shown in Figure 1, Figure 2, a kind of loudspeaker module, including shell, shell include being combined together the
Loudspeaker monomer 30 is contained in the space that one housing 10 and the second housing 20, the first housing 10 and the second housing 20 surround, is raised
Sound device monomer 30 includes vibrational system and magnetic circuit system.The vibrational system of loudspeaker monomer 30 is close to the second housing 20, loudspeaker
For the magnetic circuit system of monomer 30 close to the first housing 10, the space that the housing 20 of loudspeaker monomer 30 and second surrounds is the preceding sound of module
The space that chamber, the housing 10 of loudspeaker monomer 30 and first and the second housing 20 surround jointly is the rear operatic tunes of module.
Jointly shown with Fig. 3 as shown in Figure 1, Figure 2, the end face that loudspeaker monomer 30 is located in the rear operatic tunes is provided with two pads
32, pad 32 is used to electrically connect loudspeaker monomer 30 and module external circuit (circuit board in electronic equipment).On first housing 10
The position of corresponding two pads 32 is respectively provided with a mounting hole 12, and an electric silica gel 50 is respectively provided with two mounting holes 12, conductive
The both ends of silica gel 50 are located at the both sides of the first housing 10 respectively.It is inner side to define the first housing 10 to be located at the side of module internal,
Side outside module is outside, then one end that electric silica gel 50 is located on the inside of the first housing 10 is in contact with pad 32,
One end that electric silica gel 50 is located at the outside of the first housing 10 is in contact with module external circuit.Portable electronic is installed in module
After in equipment, it is only necessary to ensure that (i.e. the length of electric silica gel 50 is slightly larger than pad 32 to electric silica gel 50 with certain decrement
With the distance between circuit board in electronic equipment) achieve that between circuit in loudspeaker monomer 30 and portable electric appts
Electrical connection, generally the decrement of electric silica gel 50 can have good electric conductivity between 12%~30%.
As Fig. 3 and Fig. 4 are jointly shown, mounting hole 12 is circular counter sink, and the counterbore of counter sink (is relatively large in diameter
Hole) it is located at the outside of the first housing 10, the through hole (i.e. the less hole of diameter) of counter sink is located at the inner side of the first housing 10, conductive
The structure of silica gel 50 is adapted with counter sink.Electric silica gel 50 includes consolidate interior and consistent with counterbore shape size positioned at counterbore
Determine portion 52, the side that fixed part 52 is located at outside the first housing 10 is provided with first connecting portion 54, and first connecting portion 54 is cylinder,
