The invention relates to the technical field of micro motors, and discloses a multi-purpose micro motor with a good mute effect. The motor comprises a hood, buffer blocks are fixedly mounted at the bottom and the top of the inner wall of the hood, sound insulation covers are fixedly mounted on the opposite sides of the buffer blocks, first sound absorption cotton is fixedly mounted on the inner wall of the hood, and micropores are formed in the sound insulation covers. According to the multi-purpose micro motor with the good mute effect, the vibration amplitude between the motor main body and the sound insulation covers is reduced through a spring shock absorbers, and the vibration amplitude between the sound insulation covers and the hood is secondarily reduced through the buffer blocks so that the effects of multiple shock absorption and noise reduction are achieved; and second soundabsorption cotton is used for primarily absorbing the operation noise of the motor main body, the micropores in the sound insu
