<p>A personal cooling fan is integrated into a mobile electronic device (110, 210, 310). The mobile electronic device (110, 210, 310) has a vibration alert system that includes control circuitry (140, 340) to control a vibration motor (120, 320), and the personal cooling fan system is also controlled by the control circuitry (140, 340). The personal cooling fan system includes a rotary motor (130, 320) contained within a housing (112, 212, 312) of the device, a drive shaft (150, 250, 350) having a first portion engaged by the rotary motor (130, 320) and having a second portion protruding from the housing (112, 212, 312), and fan blades (160, 260, 360) removably attached to the second portion of the drive shaft (150, 250, 350) such that the rotary motor (130, 320) is operable to rotate the drive shaft (150, 250, 350) thereby spinning the fan blades (160, 260, 360). The drive shaft (150, 250, 350) may be extended from the housing (112, 212, 312) to attach the fan blades (160, 260, 360) and operate the fan, and retracted into the housing (112, 212, 312) when the fan is not in use.</p> |
