STRUCTURAL TEST

  • The ability of the product to complete the specified function under the specified conditions and within the specified time. Products in the design, application process, and constantly undergo their own and external climate environment and mechanical environment, and still need to be able to work properly, which requires the use of experimental equipment to verify it.
Bending Test
Bending Test
  • The cables will be bent during consumers are using the earphones at different intensities. It tests the limit of the number of bends at a certain strength.
USB Usage Cycle Test
USB Usage Cycle Test
  • It tests the using times of USB jacks at a certain strength.
Tensile Test
Tensile Test
  • It is used to test the corrosion resistance of a product in an environment that mimics the atmosphere.

ENVIRONMENTAL TEST

  • The products are used in different environments (outdoor use, marine transportation, carry-on) and will be subject to different environmental stresses (such as wind and rain, vibration, drops, salt spray corrosion at sea). In order to ensure that the products work properly in these environments, so environmental testing is performed.
Salty Spray Test
Salty Spray Test
