The invention discloses a vibration test method for mobile phone vibration motors, comprising the following steps: making a test tool, wherein the test tool includes a mobile phone simulation tool and a double-layer container cup, the double-layer container cup includes an inner cup and an outer cup which are concentric, and the mouth of the inner cup is lower than the mouth of the outer cup; installing a mobile phone vibration motor to be tested on the mobile phone simulation tool, and filling the inner cup with test liquid; stably placing the mobile phone simulation tool on the surface of the test liquid in the inner cup, keeping the mobile phone simulation tool afloat, and discharging the test liquid overflowing into the outer cup; and starting the mobile phone vibration motor, and when the surface of the test liquid in the inner cup is stable, measuring the amount of liquid discharged to the outer cup after the start of the mobile phone vibration motor. According to the invention, the vibration strength of the mobile phone vibration motor is measured by the amount of liquid discharged to the outer cup, devices for implementing the method are simple, easy to manufacture and assembly and very low in purchase cost, the test result can be obtained only by measuring the amount of liquid in the outer cup, operation is convenient, and the test result can be read visually.
