As a kind of preferred technical scheme, described nonmetal netted block piece is thin type structure.As optimization on this basis, described nonmetal netted block piece is intensive cavernous structure.
As a kind of preferred technical scheme, described housing is nonmetallic materials, and described nonmetal netted block piece and described non-metal shell integrated injection molding form.As preferably, described nonmetal netted block piece is nylon net cloth.As preferred technical scheme, described housing is provided with leads the operatic tunes, and the described operatic tunes of leading is communicated with described loudspeaker monomer and described phonate hole.As further preferred, described phonate hole is arranged at described housing side.As the technical scheme that another kind is optimized, the described operatic tunes of leading is interior narrow outer wide horn type structure.
The utility model loud speaker module, the phonate hole position is provided with the nonmetal netted block piece that forms with the housing integrated injection molding, when effectively regulating loud speaker module acoustical behavior, the loud speaker modular volume is not impacted, improve loud speaker module internal space availability ratio; Block piece and housing integrated injection molding form in conjunction with firmness high, avoid block piece to come off, improved the reliability of loud speaker module, nonmetal block piece can form with the non-metal shell integrated injection molding, reduced the metallic region of module, simultaneously needn't paste miscellaneous part in process of production, improve production efficiency.Therefore, it is good that the utility model loud speaker module has acoustical behavior, and reliability is high, and space availability ratio is good, the advantage that production efficiency is high.
Description of drawings
Fig. 1 is the stereogram of an embodiment of the utility model loud speaker module.
Fig. 2 is loud speaker module internal structural perspective shown in Figure 1.
Fig. 3 is loud speaker module cutaway view shown in Figure 1.
Fig. 4 is the utility model loud speaker module block piece schematic diagram.
Embodiment
, below in conjunction with accompanying drawing, describe the utility model loud speaker module concrete structure in detail.
As shown in Figure 1 to Figure 3, the utility model loud speaker module, comprise housing 1, accommodate in housing 1 and be fixed with loudspeaker monomer 2 and arrangements of electric connection (not shown), arrangements of electric connection is passed to the external electrical signal in loudspeaker monomer 2, drive loudspeaker monomer 2 sounding, the corresponding loudspeaker monomer 2 of housing 1 is provided with phonate hole 3, and the sound that loudspeaker monomer 2 sends shines outside the loud speaker module by phonate hole 3.
The utility model loud speaker module, as shown in Figure 3, the inner corresponding phonate hole of housing 13 positions are provided with block piece 4, and block piece 4 covers phonate hole 3; Block piece 4 is nonmetal network structure, by injection moulding and housing 1, is wholely set.Nonmetal cancellated block piece 4 can effectively be regulated the acoustical behavior of loud speaker module, stops that extraneous foreign matter enters the loud speaker module internal, improves the water proof and dust proof performance of module.Block piece 4 is wholely set with housing 1, can improve the firm degree of combination of block piece 4 and housing 1, avoid block piece 4 to come off, improve the reliability of loud speaker module, simultaneously, in the assembling production process of loud speaker module, needn't, miscellaneous part is pasted in phonate hole 3 positions, enhance productivity.As shown in Figure 3, block piece 4 is arranged at the loud speaker module internal and presses close to phonate hole 3 positions, improves the space availability ratio of loud speaker module.
As a kind of preferred technical scheme, the nonmetal netted block piece 4 of the utility model loud speaker module shown in the drawings is thin type structure, the nonmetal netted block piece 4 of thin type structure can reduce taking of 4 pairs of loud speaker module internal spaces of block piece, and is little on the impact of loud speaker module acoustical behavior.As shown in Figure 4, the nonmetal netted block piece 4 of the utility model loud speaker module is intensive cavernous structure, and intensive poroid nonmetal netted block piece 4 can improve the water proof and dust proof performance of loud speaker module.As preferred technical scheme, nonmetal netted block piece is nylon net cloth, and nylon net cloth can reduce the utility model loud speaker module production cost, realizes good water proof and dust proof effect.
As a kind of preferred technical scheme, for fear of the electromagnetic interference of loud speaker module metal material to the electronic product miscellaneous part, the housing of the utility model loud speaker module is nonmetallic materials, and the block piece integrated injection molding of nonmetallic housing and nonmetallic materials forms.The housing of nonmetallic materials can be combined better with nonmetal netted block piece, avoids block piece to come off, and improves the reliability of loud speaker module.
An embodiment as the utility model loud speaker module, loud speaker module shown in Figure 3, the inner corresponding loudspeaker monomer 2 of housing 1 is provided with leads the operatic tunes 12, lead the operatic tunes 12 and be communicated with loudspeaker monomer 2 and phonate hole 3, phonate hole 3 is arranged at housing 1 sidewall, and the present embodiment loud speaker module is that side is spoken.Should know, the counter structure of loud speaker module phonate hole shown in the drawings and loudspeaker monomer is only that the concrete structure of an embodiment of the utility model loud speaker module embodies, its purpose, for explanation the utility model loud speaker modular structure, does not impose any restrictions the utility model loud speaker module.
