Description of drawings
By below in conjunction with accompanying drawing the utility model being described, above-mentioned feature of the present utility model and technological merit will become apparent and understand easily.
Fig. 1 is the three-dimensional decomposition texture schematic diagram of the utility model loud speaker module.
Fig. 2 is the cross-sectional view of the utility model loud speaker module.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done further detailed description.
As depicted in figs. 1 and 2, the loud speaker module comprises peripheral housing and is contained in the interior loudspeaker monomer 2 of described peripheral housing, peripheral housing comprises that first housing 1 and second housing 3 are so that the assembling of loud speaker module, present embodiment second housing 3 is loudspeaker monomer 2 fixedly, the position of loudspeaker monomer 2 and second housing, 3 sides forms the back operatic tunes 4 of loud speaker module, and the back operatic tunes 4 is the structure of sealing.Present embodiment loud speaker module is positive structure of speaking, and second housing 3 is provided with phonate hole 30 over against a side of loudspeaker monomer 2 vibrating diaphragms, and as shown in Figure 2, the back operatic tunes 4 is positioned at the side away from phonate hole 30.In the present embodiment, the back operatic tunes 4 is divided into a plurality of cavitys by some retaining walls, connects by slit between the adjacent cavity.
Wherein, second housing 3 is provided with the first adjacent retaining wall 31 that is arranged side by side, the very narrow formation slit 310 of spacing between two first retaining walls 31, has certain interval between the sidewall of two first retaining walls 310 and second housing 3, and the gap of two first retaining walls 310 is positioned at opposite position, and the cavity of two first retaining walls, 31 both sides is communicated with by slit 310.The sound that loudspeaker monomer 2 produces passes the gap near first retaining wall 31 of loudspeaker monomer 2 one sides, pass slit 310 then, the gap of passing at last away from first retaining wall 31 of loudspeaker monomer 2 one sides arrives in the cavity of the back operatic tunes 4 away from loudspeaker monomer 2 one sides.This structure that first retaining wall 31 is set in the operatic tunes 4 of back, the back operatic tunes 4 is divided into a plurality of cavitys, be communicated with to increase acoustic resistance by the slit between first retaining wall 31 between a plurality of cavitys, thereby avoided the influence owing to the too small heimholtz resonator that causes of the back excessive monomer phonate hole of the operatic tunes 4 volumes, improved the acoustical behavior of product.In addition, present embodiment second housing 3 is the sleeve configuration structure, loudspeaker monomer 2 is arranged at position intermediate, in order to cooperate the back operatic tunes 4 of the sleeve configuration that this sleeve configuration second housing 3 forms, present embodiment comprises two group of first retaining wall 31 and the slit 310 thereof that is arranged side by side, the such structure of many groups is set the back operatic tunes 4 of this sleeve configuration can be separated into more cavity, prevented the generation of heimholtz resonator acoustic resonator, improved the acoustical behavior of product.
In addition, slit is not limited to the structure of this set between adjacent retaining wall, also can occur with other forms of structure, for example, can be arranged on the retaining wall.As depicted in figs. 1 and 2, also be provided with second retaining wall 32 that the back operatic tunes is divided into some cavitys behind the loud speaker module in the operatic tunes 4, the two ends of second retaining wall 32 all can join with the sidewall of second housing 3, are provided with the slit 320 that is communicated with second retaining wall, 32 both sides cavitys at second retaining wall 32.Slit 320 can increase the acoustic resistance in the back operatic tunes 4 equally, reduces the generation of standing wave, improves the acoustical behavior of product.In addition, the quantity of present embodiment second retaining wall 32 also is two, with the sound in the operatic tunes behind this sleeve configuration of better adjustment present embodiment 4, improves the acoustical behavior of product.
Need to prove that the back operatic tunes 4 seals, and only can be communicated with by slit between the adjacent cavity.Therefore, first retaining wall 31 and second retaining wall 32 can be connected to first housing 1 over against the inner surface of loudspeaker monomer 2, by retaining wall with each cavity separately, adjacent cavity only can be connected by slit.Perhaps, in the inboard position corresponding with first retaining wall 31 and second retaining wall 32 of first housing 1 retaining wall is set also, and dock with first retaining wall 31 and second retaining wall 32, the cavity that separates with formation.In the present embodiment, first retaining wall 31, second retaining wall 32 are consistent with the height of second housing, 3 sidewalls, this structure fabrication technology simply is easy to moulding, first housing 1 and second housing 3 are by the mode secure bond of ultrasonic bonding, because the sidewall of first housing 1 also has certain height, therefore, first retaining wall 31, second retaining wall 32 and first housing 1 have certain distance over against between the inner surface of loudspeaker monomer 2.Can only be communicated with by slit in order to make between each cavity, present embodiment is provided with between first housing, 1 inner surface and first retaining wall 31, second retaining wall 32 and is connected pad 10, preferably, the thickness that connects pad 10 is consistent with the height of first housing, 1 sidewall, as depicted in figs. 1 and 2, wherein, connect pad 10 and can be foam, also can be the gas-adsorbing material material, as carbon fiber nonwoven fabric etc., if adopt the gas absorption material then taking full advantage of the equivalent volume of further having expanded the back operatic tunes 4 under the situation of inner space, improved the low frequency sound effect of product.
