Embodiment 1

[0024] Such as figure 1 , figure 2 Shown, a kind of vibration testing method of mobile phone vibrating motor comprises the following steps:

[0025] A. Make test tooling, including mobile phone simulation tooling 1 and double-layer container cup 2 made of glass. The double-layer container cup includes concentric inner cup 3 and outer cup 4, and the mouth of inner cup 3 is lower than the mouth of outer cup 4. The center of the bottom of the inner cup 4 is integrally provided with a pit, and the center of the bottom of the inner cup 3 and the outer cup is integrally provided with a convex pin. The cup 4 is assembled, and the gap between the inner cup 3 and the outer cup 4 is sealed with glass glue. Scale is marked on the 4 cup walls of the outer cup. A drain valve 6 is provided on the outer edge of the bottom of the outer cup 4, and a manual handle is provided on the drain valve 6;

[0026] B. Install the mobile phone vibration motor to be tested on the mobile phone simul...

Abstract

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.

Description

technical field [0001] The invention relates to a method for detecting components of a mobile phone, in particular to a method for testing vibration of a vibration motor of a mobile phone. Background technique [0002] Conventional vibration motors on the market are classified into flat motors, cylindrical hollow cup motors, SMT chip motors, linear motors, etc. according to their structure. Mobile phone vibration motors are mainly used in mobile phone applications, including incoming calls, text message vibration reminders, entertainment game vibration tactile sensation, etc. The definition of the function of the vibration motor of the mobile phone is to enable the mobile phone to transmit information through vibration during the application process. In normal use, the part of the human body that is usually in contact with it is transmitted to the brain through the nerves. The size of the transmitted vibration is determined by the vibration of the human skin surface feedbac...
