As the preferred technical scheme of one, described the first housing is provided with sheet metal with corresponding described loudspeaker monomer fixed position on described the second housing.
As further preferred, described sheet metal and described the first housing, described sheet metal and described the second housing all adopt injection moulding integrated molding to form.
The utility model loud speaker module, adopts foam to separate ante-chamber and back cavity, and housing need not adopt extra injection structure to separate the front and back operatic tunes, reduces housing injection moulding difficulty; The utility model loud speaker module, Air Filter is arranged on the first housing in sound channel, and Air Filter is separated into two parts by sound channel and prevents that external dust from entering loudspeaker monomer, simultaneously, be arranged at the Air Filter difficult drop-off of module internal, improve the reliability that Air Filter is combined with housing.Therefore, it is high that the utility model loud speaker module has the reliability that Air Filter is combined with housing, the simple advantage of module casing manufacture.
Accompanying drawing explanation
Fig. 1 is the utility model loud speaker module embodiment three-dimensional cutaway view;
Fig. 2 is the cutaway view of loud speaker module shown in Fig. 1;
Fig. 3 is the I of loud speaker module shown in Fig. 1 part enlarged drawing.
Embodiment
Below in conjunction with accompanying drawing, describe the utility model loud speaker module concrete structure in detail.
As depicted in figs. 1 and 2, the utility model loud speaker module, comprises the first housing 11, the second housings 12 and loudspeaker monomer 2; The first housing 11 and the second housing 12 form the utility model loud speaker module shell, and loudspeaker monomer 2 is accommodated and is fixed in shell, and described side wall of outer shell is provided with phonate hole 3.The first housing 11 and the second housing 12 surround cavity, and as shown in Figures 1 and 2, the empty cavity position between the first housing 11 and the second housing 12 is provided with foam 5, and foam 5 is separated into ante-chamber and back cavity by cavity, and front cavity segment and loudspeaker monomer 2 position of speaking is communicated with.As shown in Figure 2, foam 5 coordinates with the first housing 11, the second housing 12, forms the sound channel 6 for sound transmission, and above-mentioned ante-chamber is communicated with sound channel 6, and sound channel 6 is communicated with phonate hole 3; The sound that loudspeaker monomer 2 sends is passed to sound channel 6 via ante-chamber, after the interior propagation of sound channel 6, by phonate hole 3, is passed to loud speaker module outside.As depicted in figs. 1 and 2, in sound channel 6, on the first housing 11, Air Filter 4 is installed, Air Filter 4 is separated into two parts by sound channel 6, and extraneous dust cannot enter loudspeaker monomer 2.The utility model loud speaker module, adopt foam 5 to separate chamber, front and back, needn't on housing, adopt injection structure to separate chamber, front and back, reduce housing production difficulty, Air Filter 4 is arranged in sound channel 6, when avoiding extraneous dust to enter loudspeaker monomer 2, avoid Air Filter 4 in loud speaker module installation process to come off, improve the reliability that Air Filter 4 is combined with housing.
As the preferred technical scheme of one, as shown in figures 1 and 3, the first housing 11 inner close loudspeaker monomer 2 positions in the utility model loud speaker module sound channel 6 are provided with the first bonding plane 112, the first housing 11 is provided with the second bonding plane 113 near corresponding the first bonding plane 112 in phonate hole 3 positions, and sound channel 6 is separated the first bonding plane 112 and the second bonding plane 113.As shown in Figure 3, the first bonding plane 112 and the second bonding plane 113 are all obliquely installed, and the first bonding plane 112 and the second bonding plane 113 are positioned on same clinoplain.Air Filter 4 two ends are adhesively fixed with the first bonding plane 112 and the second bonding plane 113 respectively.The Air Filter 4 of design is obliquely installed in sound channel 6 like this, improved the firm degree of Air Filter 4 and the first housing 11, avoid Air Filter 4 to come off and cause extraneous dust to enter loudspeaker monomer 2 in the use procedure of loud speaker module, improve loud speaker module reliability.
For the seal of the separation in chamber before and after guaranteeing, as depicted in figs. 1 and 2, foam 5 is arranged at the empty cavity position between the first housing 11 and the second housing, and foam 5 is adhesively fixed on the first housing 11.Foam 5 and the first housing 11 are adhesively fixed, when before and after guaranteeing, the operatic tunes is separated seal, when the production and assembly of loud speaker module, directly the first housing 11 and second housing 12 combinations of foam 5 will be fixed with, foam 5 need not be set separately, simplify production technology, enhance productivity.As preferably, as depicted in figs. 1 and 2, the utility model loud speaker module the first housing 11 and the corresponding loudspeaker monomer of the second housing 12 2 fixed positions are respectively arranged with sheet metal 111 and sheet metal 121.Sheet metal can reduce thickness under the prerequisite of proof strength, the sheet metal 111 arranging on the first housing 11 and the second housing 12 and sheet metal 121 can improve the space of loudspeaker monomer 2 fixed positions, can in the situation that not increasing loud speaker modular volume, improve loudspeaker monomer 2 sizes, improve loud speaker module acoustical behavior.Sheet metal and housing adopt integrated injection molding, can reduce loud speaker module group assembling difficulty, improve loud speaker module production efficiency.
The utility model loud speaker module, adopts foam to separate the module internal front and back operatic tunes, and module casing needn't additionally arrange injection structure, has reduced the manufacture difficulty of housing; Air Filter is arranged at module internal, avoids loud speaker module to come off being installed to Air Filter in electronic product process, improves the reliability that Air Filter is combined with module casing.
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.
