FIELD: process engineering.SUBSTANCE: invention relates o vibrators and method related therewith and consisting in automatic extension and return of unbalanced mass used to create vibration relative to motor housing subject to current operating conditions of vibrator system. Claimed set of inventions covers communication device including vibrator 108 and method of creating vibrations in device including motor, shaft and unbalanced mass. Note here that vibrator motor comprises shaft (112) engaged with motor (110) to excite vibrations in communication device 500. Shaft (112) includes guide way to define path with first component displacing in circle about shaft (112) and second component displacing along shaft (112). Shaft (112) is driven by motor (110). Unbalanced mass (114) displaces along the guide way when the motor (110) is activated and returns owing to displacing force of tensioner (212), wheh the motor (110) is deactivated.EFFECT: ruled out damage of vibrator shaft.19 cl, 6 dwg |
