Abstract

The utility model discloses a loudspeaker module. The loudspeaker module comprises a housing and a loudspeaker single body disposed inside and fixed to the housing. The housing is provided with a sound hole for emitting sound. The housing is internally provided with a sound leading tube corresponding to the loudspeaker single body. The sound leading tube is communicated with the loudspeaker single body and the sound hole of the housing. The sound hole is disposed on the sidewall of the housing. The sound leading tube is internally provided with sound-absorbing cotton near the sound hole. The loudspeaker module is advantaged by being good in acoustic performance.

Description

Loud speaker module
Technical field
The utility model relates to electroacoustic field, especially relates to a kind of loud speaker module.
Background technology
Along with the expansion in consumer electronics market, the consumer electronics products such as a large amount of mobile phones, notebook computer are used widely, and as acoustic element important in consumer electronics product, loud speaker module has demand widely.Along with the raising that people require consumer electronics product, the performance of loud speaker module also more and more receives people's concern.
Loud speaker module, comprises housing, accommodates the loudspeaker monomer being fixed in housing, is provided with phonate hole on housing, and the sound that loudspeaker monomer sends shines outside module by phonate hole.The loud speaker module of prior art, in housing, sound guide tube is communicated with loudspeaker monomer and phonate hole, and during loudspeaker monomer work, vibrating diaphragm vibration causes variations in flow in sound guide tube, and air-flow and sound guide tube friction can produce noise, and loud speaker module acoustical behavior is exerted an influence.
Therefore, be necessary to propose a kind of improvement and overcome prior art loud speaker module defect.
Utility model content
The side that it is good that technical problem to be solved in the utility model the is to provide a kind of acoustical behavior loud speaker module of speaking.
To achieve these goals, the utility model is by the following technical solutions:
A kind of loud speaker module, comprise housing, accommodate the loudspeaker monomer being fixed in described housing, on described housing, be provided with the phonate hole for sound outgoing, and: in described housing, corresponding described loudspeaker monomer is provided with sound guide tube, described sound guide tube is communicated with described loudspeaker monomer and described housing phonate hole, and described phonate hole is arranged at described housing sidewall, in described sound guide tube, near described phonate hole position, is provided with acoustical cotton.
As the preferred technical scheme of one, in described housing, be provided with host cavity, described loudspeaker monomer is accommodated and is fixed in described host cavity.As further preferred, the inwall that the corresponding described loudspeaker monomer of described host cavity is installed is provided with guide vane end stop, and described guide vane end stop contacts with described loudspeaker monomer, and described loudspeaker monomer is limited in described housing by described guide vane end stop; Meanwhile, described guide vane end stop is multiple; Described guide vane end stop and described housing are wholely set, and described guide vane end stop is the projection being arranged on described housing.
The utility model loud speaker module, phonate hole is arranged at housing sidewall, by sound guide tube, is communicated with loudspeaker monomer and phonate hole, can avoid the dust of module outside directly to enter enclosure interior loudspeaker monomer is exerted an influence; Sound guide tube is provided with acoustical cotton near phonate hole position, and acoustical cotton can slow down the flow velocity of air-flow in sound guide tube, reduces air-flow and the fricative noise of sound guide tube, improves loud speaker module acoustical behavior; The design of acoustical cotton can also further prevent that external dust from entering enclosure interior, improves loud speaker module reliability.

Embodiment
Below in conjunction with accompanying drawing, describe the utility model loud speaker module in detail.
As shown in drawings, the utility model loud speaker module, comprises housing 1, is provided with host cavity 12 in housing 1, accommodates fixing loudspeaker monomer 2 in host cavity 12.The utility model loud speaker module, loudspeaker monomer 2 is electrically connected with external electronic circuits by arrangements of electric connection (not shown), the signal of telecommunication of external circuit enters in loudspeaker monomer 2 by arrangements of electric connection, drive loudspeaker monomer 2 sounding, the sound that loudspeaker monomer 2 sends is from being arranged at the phonate hole 3 position outgoing housing 1, loud speaker module sounding.
As shown in Figure 3 and Figure 4, be provided with sound guide tube and be communicated with loudspeaker monomer 2 and phonate hole 3 in loud speaker module casing 1, phonate hole 3 is arranged at housing 1 side, and sound guide tube is provided with acoustical cotton 4 near the position of phonate hole 3.The phonate hole 3 that is arranged at side can prevent that module external dust from directly entering module internal and loudspeaker monomer 2 is impacted, improve loud speaker module reliability, simultaneously, at sound guide tube, near phonate hole 3 positions, be provided with acoustical cotton 4, acoustical cotton 4 can slow down the flow velocity of air-flow in sound guide tube, reduces air-flow and the fricative noise of sound guide tube, improve loud speaker module acoustical behavior, meanwhile, acoustical cotton 4 can also avoid module external dust to enter module internal, improves module reliability.
As shown in Figure 4, be provided with host cavity 12 in loud speaker module casing 1, as shown in Figures 2 and 3, loudspeaker monomer 2 is accommodated and is fixed in host cavity 12.In order to guarantee the positioning precision of loudspeaker monomer 2 in host cavity 12, the fixing difficulty of loudspeaker monomer 2 and housing 1 in reduction loud speaker module group assembling process, as shown in Figure 5, the utility model loud speaker module host cavity 12 inwalls are provided with guide vane end stop 5, by guide vane end stop 5, can accurately locate loudspeaker monomer 2.In order to guarantee loud speaker module reliability, simplify the production technology of housing 1 simultaneously, guide vane end stop 5 is the projection on housing 1, one-body molded with housing 1.
The utility model loud speaker module, phonate hole is arranged at housing sidewall, by sound guide tube, be communicated with loudspeaker monomer and phonate hole, sound guide tube is provided with acoustical cotton near phonate hole position, to slow down the flow velocity of air-flow in sound guide tube, reduce air-flow and the fricative noise of sound guide tube, improve loud speaker module acoustical behavior.As preferred technical scheme, the inner corresponding loudspeaker monomer of loud speaker module casing is provided with guide vane end stop, to improve loudspeaker monomer positioning precision in housing, reduces loudspeaker monomer and the fixing difficulty of housing in assembling process.
These are only the utility model case study on implementation, be not limited to the utility model, as long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection range of recording in claims.
