Automatic resonant type sound insulation oscillator is hung in control

Automatic resonant type sound insulation oscillator is hung in control, including sound -proof box, sound -proof box is the upper portion open -ended box of acoustic celotex board preparation, and sound -proof box upper portion sets up the acoustic celotex board, and acoustic celotex board and sound -proof box constitute the confined box, and the first spring of several is connected to the acoustic celotex board bottom, the lower extreme connection extension rod of first spring, the utility model discloses utilize rotating electrical machines and eccentric weight to combine together, it is rotatory to drive eccentric weight when rotatory motor output shaft is rotatory, makes layer board and beaker produce vibrations to turn into the shock with original stirring to liquid in the beaker, thereby play more soft liquid mixing effect. The utility model discloses a second spring and first spring combine together, can utilize elasticity to produce a plurality of supplementary vibrations aftervibrations are once take
