Overview

Product Description: The headphone expansion testing machine is suitable for testing the stretch fatigue strength of headphone ear clips. This machine is used to place the two ends of the product on a clamping device that has adjusted the test stroke, set the test times, and stop working after reaching the set number of times to check for product damage. The headphone expansion testing machine, also known as the headphone headband expansion durability testing machine, headphone extension life testing machine, etc., is a specialized equipment designed to simulate and test the durability and reliability of the headband or extension arm of headphones that undergo repeated expansion and contraction during long-term use.

1、 Core use and purpose

Its main purpose is to accelerate the testing of the headphone head by simulating the actions of a real person wearing and removing headphones in a laboratory environmentMechanical fatigue lifeandMaterial durability.

The specific testing objectives include:

Assess lifespan:Determine how many expansion retraction cycles the earphone head will experience before it fractures, deforms, relaxes, or fails to function.
Testing structural strength:Verify whether the structural design and material selection of key components such as headrests, telescopic arms, and hinges are reasonable.
Quality Control:As part of the production and quality control process, ensure that the factory products meet the predetermined durability standards.
R&D improvement:Provide data support for new product development, discover design defects through testing, and optimize and improve accordingly.

VR/AR headset devicesIts head mounted structure is similar to headphones and also requires durability testing.
Other wearable devices with retractable headgear

3、 Working principle and testing process of equipment

Clamping and fixing:Fix the two earmuffs of the headphones onto the two fixtures of the machine.
Simulated action:

Expansion:Two fixtures move outward according to a preset stroke (distance) to simulate the action of putting headphones on from the head.
Maintain/contract:After the fixture reaches its maximum position, it may briefly hold and then move inward back to its initial position, simulating the natural state of the headphones when they are restored to their original state or worn on the head.

move in circles:The above actions are repeated continuously at a set speed (such as how many cycles per minute) until the preset number of cycles is reached or the headphones are damaged.
Monitoring and recording:The equipment is usually equipped with a counter to record the total number of cycles. Advanced models may also come with sensors to monitor changes in force during testing, in order to determine if plastic deformation or component damage has occurred.
