Abstract

The utility model discloses a kind of damping device of English Phonetics public address equipment, it is related to phonetic teaching equipment field.It is filled with the outter box of the damping device of the English Phonetics public address equipment on damping filler, damping filler and is fixed with open-topped rectangular box shape inner box, is not contacted between inner box and outter box.English Phonetics public address equipment can be placed on when using in inner box, outter box is placed on the table again, because damping filler is manufactured by the silicon gel of g., jelly-like, silicon gel has good shock-absorbing and cushioning effect, it can ensure that the vibrations of English Phonetics public address equipment are at utmost weakened, so as to promote public address equipment not occur trill, tonequality is apparent, voice delivery is more effective, and damping effect is good.

Description

The damping device of English Phonetics public address equipment

Technical field

The utility model is related to teaching equipment field, relates in particular to a kind of damping dress of English Phonetics public address equipment Put.

Background technology

English Phonetics teacher at school when can usually carry portable public address equipment, so that every student can clearly listen To the pronunciation of teacher, phonetic teaching effect is improved.But public address equipment can usually shake when playing, and influence having for sound Effect spread, allows some students can not listen the voice content for differentiating Chu teacher.

Utility model content

The utility model is designed mainly solving the technical problems that provide a kind of damping device of English Phonetics public address equipment Simply, the vibrations that English Phonetics public address equipment occurs can be minimized, ensures voice public address equipment normal work, damping effect Well.

To achieve the above object, the utility model provides following technical scheme：A kind of English Phonetics public address equipment subtracts Device is shaken, the damping device of the English Phonetics public address equipment includes filling out in open-topped rectangular box shape outter box, outter box Filled with damping filler, open-topped rectangular box shape inner box is fixed with damping filler, is not connect between inner box and outter box Touch.

As the further optimization of the technical program, the outter box is with inner box by plastic manufacturing.

As the further optimization of the technical program, the damping filler is manufactured by silicon gel.

Beneficial effect using above technical scheme is：Filled out in the outter box of the damping device of the English Phonetics public address equipment Filled with damping filler, open-topped rectangular box shape inner box is fixed with damping filler, is not connect between inner box and outter box Touch.English Phonetics public address equipment can be placed on when using in inner box, then outter box is placed on the table, because damping is filled out Expect to be manufactured by the silicon gel of g., jelly-like, silicon gel has good absorbing and cushioning effect, can ensure English Phonetics The vibrations of public address equipment are at utmost weakened, so as to promote public address equipment not occur trill, tonequality is apparent, and voice delivery is more Effectively, damping effect is good.

Brief description of the drawings

Embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.

Fig. 1 is a kind of structural representation of the damping device of English Phonetics public address equipment of the utility model.

Wherein, 1-outter box, 2-inner box, 3-damping filler.

Embodiment

Describe a kind of preferred reality of the damping device of English Phonetics public address equipment of the utility model in detail below in conjunction with the accompanying drawings Apply mode.

Fig. 1 shows a kind of embodiment of the damping device of English Phonetics public address equipment of the utility model：The English The damping device of voice public address equipment includes being filled with damping filler 3 in open-topped rectangular box shape outter box 1, outter box 1, Open-topped rectangular box shape inner box 2 is fixed with damping filler 3, is not contacted between inner box 2 and outter box 1.

As shown in figure 1, outter box 1 and inner box 2 are by plastic manufacturing, it is durable, and low cost.Damping filler 3 are manufactured by silicon gel, are in g., jelly-like under silicon gel normal temperature, and there is silicon gel good shock-absorbing and damping to make With.

English Phonetics public address equipment can be placed on inner box 2 by the damping device of the English Phonetics public address equipment when in use It is interior, then outter box 1 is placed on the table, because damping filler 3 is manufactured by the silicon gel of g., jelly-like, silicon gel tool There are good shock-absorbing and cushioning effect, can ensure that the vibrations of English Phonetics public address equipment are at utmost weakened, so as to promote to expand Trill does not occur for sound equipment, and tonequality is apparent, and voice delivery is more effective, and damping effect is good.
