A dust test system includes a test chamber, a vibration apparatus mounted on the test chamber and a vibration control circuit electrically connected to the vibration apparatus. The test chamber is adapted to accommodate an electronic device. The vibration apparatus includes a vibration sieve mounted on the test chamber and at least one vibration motor linkage to the vibration sieve. A plurality of dust is laid on the vibration sieve. The vibration control circuit is adapted to receive a first AC voltage, and output a second AC voltage according to the first AC voltage. The at least one vibration motor is adapted to receive the second AC voltage and vibrate. The vibration sieve is adapted to vibrate together with the at least one vibration motor. The plurality of dust lying on the vibration sieve are dropped into the test chamber.
