Abstract
The utility model relates to a foam inner packing for loudspeaker, which contains a flat plate. The flat plate has at least two groups of big round holes and small round holes. The positions of each group of big round holes and small round holes are arranged reversely. The diameter of the big round hole is accordant with the mouth diameter of the loudspeaker, and the diameter of the small round hole is accordant with the diameter of the backseat of the loudspeaker. The utility model is provided with at least two groups of big round holes and small round hole which are alternately and reversely arranged to fix the mouth and the backseat of the loudspeaker so as to greatly reduce the use of foam and more effectively save space. Because the flat plates at both sides are identical, only one mold is used when the foam inner packing for loudspeaker is brought into production; furthermore, the processing accomplished by several groups of big round holes and small round holes is very convenient.
Description
Technical field
The utility model relates to a kind of packing box structure, specifically is a kind of foam inner packing of loud speaker.
Technical background
Foam inner packing such as Fig. 1 of existing loud speaker, shown in 2, adopt the foam shell 1 of two symmetries, from two sides of loud speaker with the whole sealing of loud speaker be wrapped in the cavity 2 in the foam, described cavity 2 shapes and loud speaker profile adapt, rectangular depression 3 structures that are connected to cavity 2 external diameters in two are arranged in housing 1, this structure not only causes waste to material, and structure more complicated, in addition, though the foam shell 1 of two symmetries of both sides is the shape symmetry, not quite identical, in the process of manufacture, two moulds to be arranged at least, make troubles to processing.
The utility model content
The utility model has overcome above-mentioned shortcoming, and the utility model provides the foam inner packing of a kind of simple and compact for structure, economical with materials, loud speaker easy to process.
The technical scheme in the invention for solving the technical problem is: comprise a flat board, described flat board is provided with at least two group big hole and small sircle holes, and the position of the large and small circular hole between every group is put upside down setting mutually.
The diameter of big hole can adapt with loud speaker oral area diameter, and the diameter of small sircle hole can adapt with loud speaker back seat diameter.
Can be provided with a circle step in the described big hole.
Can be provided with a circle step in the described small sircle hole.
Can be provided with four bulge-structures around circular hole around the described small sircle hole.
Can be provided with the strip shape groove on the platen surface between described small sircle hole and the described plate edge.
Can be provided with at least one fin in the described groove.
The described dull and stereotyped back side can be provided with the strip shape groove on the platen surface on the two small sircle hole lines of centres.
Can be provided with circular groove on the platen surface between cooresponding one jiao of described big hole and described flat board.
The utility model is provided with the big small sircle hole that at least two groups alternately are placed upside down by the foam flat board, the oral area and the back seat two ends of loud speaker are fixed, thereby greatly reduce the use of foamed materials, and can more effectively get conserve space, because both sides is dull and stereotyped identical, when putting into production, only use same mould to get final product, processing easily, in addition by some groups of big small sircle holes.

The specific embodiment
As Fig. 3,4,5, shown in 6, on dull and stereotyped 4 three groups of big holes 5 and small sircle hole 6 are arranged, the diameter of big hole 5 and the mouth diameters of loud speaker adapt, the back seat diameter of small sircle hole 6 diameters and loud speaker adapts, the position of three groups of big holes 5 and small sircle hole 6 is put upside down setting mutually, the inside circular step 7 of one circle is arranged in each big hole 5, be used to locate the oral area of loud speaker, the inside circular step 8 of one circle is also arranged in each small sircle hole 6, be used to locate the back seat of loud speaker, around each small sircle hole 6, four projectioies 9 are arranged, the inward flange diameter of four projectioies 9 is identical with small sircle hole 6 diameters, this structure can make the back seat of loud speaker locate better, on the plane between small sircle hole 6 and dull and stereotyped 4 edges, five strip shape grooves 10 are arranged, these groove 10 structures can be saved the part raw MAT'L, in described each strip shape groove 10, at least one fin 11 is arranged, length on strip shape groove 10 is decided, in the short groove 10 fin 11 can be set, in the long groove 10 two or more fins 11 are set, the height of fin 11 is not higher than the degree of depth of groove 10, this structure has also guaranteed dull and stereotyped 4 intensity on the basis of having saved material, facing mutually two of dull and stereotyped 4 back sides also has same strip shape groove 12 and fin 13 on the line between the small sircle hole 6, also can play the effect of same saving in material.
Running condition as shown in Figure 6, put upside down two identical this kind foam inner packing I and II staggered relatively mutually, be that the two is relatively positive, the big hole 5 of I plate is coaxial relative with the small sircle hole of II 6, the oral area of a loud speaker a is stuck in the step 7 in the big hole 5 of I, the back seat of this loud speaker is stuck in step 8 and four projectioies 9 centres of the small sircle hole 6 of II, the direction of another loud speaker b is just in time opposite with it, be about on the step 7 of big hole 5 that oral area is stuck in II, back seat is stuck in the middle of the step 8 and four projectioies 9 of small sircle hole 6 of I.Because the section shape of loud speaker is trapezoidal, thus the loud speaker of arranging so alternately can be placed upside down mutually some right, to reach space-saving effect.In addition, between dull and stereotyped 4 front small sircle holes 6 and dull and stereotyped 4 edges and on dull and stereotyped 4 back side small sircle holes, 6 lines of centres, be respectively arranged with strip shape groove 10, the groove front has five, the back side has two, and 1 or 2 fin 11 is arranged in each groove, and this structure can guarantee to reduce raw-material use as far as possible under the situation that does not influence dull and stereotyped semi-finals degree, on the plane between big hole 5 and dull and stereotyped 4 cooresponding one jiao, two circle hole shape grooves 14 are arranged also, play the effect of economical with materials too.
