Description

Technical Field

[0001] The utility model relates to the field of Bluetooth earphones, in particular to a universal audio testing platform for Bluetooth earphones. Background Art

[0002] Bluetooth headset audio testing is a process that uses a series of precise measurement and evaluation methods to ensure that the headset meets design standards and user expectations in terms of sound quality, volume, noise suppression, Bluetooth connection stability and latency. This process covers audio response analysis from low to high frequencies, verification of sound clarity and detail reproduction capabilities, as well as call quality and music playback effect testing under different environmental conditions (such as noisy environments), aiming to provide an excellent listening experience.

[0003] The existing Chinese patent with announcement number CN220965164U discloses a universal audio test platform for Bluetooth headsets, including a test bench, the top of which is fixedly connected to a test box, the top surface of which is rotatably connected to a soundproof top cover via a hinge, and the interior of the test box is fixedly connected to a carrier plate. The advantage of this utility model is that when it is necessary to perform audio testing on the Bluetooth headset, the soundproof top cover can be opened, and the threaded column can be rotated to drive the clamping plate upward through the threaded transmission. The bottom of the Bluetooth headset is then placed in a suitable clamping groove. Different clamping grooves can be selected according to the model of the headset, and it can be suitable for Bluetooth headsets of different models and specifications. The threaded column is then reversed to drive the clamping plate downward. The headset can be fixed by squeezing between the clamping plate and the clamping seat. The provision of anti-slip strips not only makes the clamping more stable, but also prevents the headset from being crushed.

[0004] Most of the above-mentioned solutions and the test platforms under the existing technology only perform simple clamping for testing, and cannot simulate the actual in-ear wearing and sound reception effects of the headphones. The lack of corresponding structure here requires improvement and optimization. Utility Model Content
