Description

Technical Field

[0001] The utility model relates to the technical field of electronic product function detection, in particular to a mobile phone vibration motor testing device. Background Art

[0002] A mobile phone vibration motor is a small device in a smartphone that primarily provides tactile feedback. It typically consists of a tiny metal rod (vibrator) and a coil. Electric current generates a magnetic field in the coil, causing the vibrator to vibrate under electromagnetic force. This vibration is then transmitted to the phone's casing, creating a vibration effect. This feedback mechanism helps users better perceive the results of actions such as swiping and clicking, enhancing the user experience. With technological advancements, the performance of mobile phone vibration motors has continued to improve, evolving from traditional rotor motors to linear motors, resulting in more refined and diverse vibration effects.

[0003] The China Patent Network discloses an automatic testing device for a mobile phone vibration motor, with the publication number CN218276819U. Although the mobile phone vibration motor is placed between the main rotating disk and the auxiliary rotating disk, the clamping member drives the auxiliary rotating disk to clamp the motor between the main rotating disk and the auxiliary rotating disk. By rotating the main rotating disk to rotate by the rotating motor, the vibration motor can rotate along with the main rotating disk and the auxiliary rotating disk, so that the tester can comprehensively test the mobile phone vibration motor and improve the test accuracy. However, the tester in this patent is fixedly connected, making it inconvenient to disassemble and maintain, which has obvious defects.

[0004] Therefore, a mobile phone vibration motor testing device is proposed. Utility Model Content
