Description

Technical Field

[0001] The utility model relates to the technical field of electronic device testing, in particular to a tool for testing the bonding force of a headphone magnet basin frame. Background Art

[0002] When headphones are produced, the magnets and the frame are usually glued together. Good bonding means that the connection between the magnets and the frame is more secure, and can withstand long-term use and possible external factors such as vibration and impact, thus extending the service life of the product. If the bonding between the magnets and the frame is insufficient, the magnet position will be offset or the vibration will be unstable, thus affecting the sound quality.

[0003] Currently, there is no professional equipment for testing the bonding strength between magnetic basin frames. Usually, the magnetic basin frames are pulled manually, and the two are not pulled apart. This testing method is not reliable. Some workers have relatively weak strength, and are unable to pull the two apart when faced with magnetic basin frames with insufficient bonding strength. Even workers with relatively strong strength will have their physical strength reduced after multiple manual pulling tests, so patented testing equipment is needed. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:
