As the air flows through the slits and out through the front of the fan, the air be­hind the fan is drawn through the tube as well. This is be­cause of the prin­ci­ple of in­duce­ment, where the flow­ing air be­ing pushed out by the mo­tor in­duces the air be­hind the fan to fol­low it through the fan.

When this hap­pens, a low-pres­sure re­gion is cre­ated, mak­ing the air sur­round­ing the edges of the fan to also start to flow in the di­rec­tion of the breeze, in­creas­ing the over­all strength of the breeze you feel.

3. The in­te­rior of the tube acts as a ramp, which goes around the in­side of the tube and out to­ward the front of the fan.

4. To re­duce the noise cre­ated from the tur­bu­lence gen­er­ated from suck­ing air through the base of the Mul­ti­plier, a Helmholtz cav­ity was in­te­grated into the fan’s base to can­cel out the ex­tra sound cre­ated by us­ing the prin­ci­ple of res­o­nance. The end re­sult: a stream of wind that stays quiet de­spite the level.
