The detection principle of the microphone waterproof and breathable membrane is mainly based on its waterproof and breathable characteristics. In the detection process, the following methods are commonly employed:
Air pressure detection method: By inflating the inside of the waterproof breathable membrane of the microphone, the breathability of the microphone is tested. Specifically, under a certain air pressure, the waterproof breathable membrane of the microphone head should be able to keep the air pressure stable, without obvious air pressure drop or leakage, and at the same time be able to effectively discharge the internal gas and maintain good air permeability.
Water pressure detection method: By applying water pressure to the outside of the waterproof breathable membrane of the microphone, the waterproof performance is tested. Specifically, under a certain water pressure, the waterproof and breathable membrane of the microphone head should be able to maintain no water leakage and no obvious leakage, while being able to effectively withstand water pressure and maintain good mechanical properties.
Appearance and size inspection method: By checking the appearance and size of the microphone waterproof and breathable membrane, it is tested whether it meets the relevant standards and specifications. Specifically, it should be checked whether the surface quality, color, dimensional accuracy, etc. of the membrane meet the requirements of the standard, and there are no obvious defects or damage.
Durability testing method: test the durability of the waterproof breathable membrane of the microphone in different environments to test its service life and stability. Specifically, it can be tested in different temperature, humidity, and ultraviolet lamp environments to observe the performance changes and aging of the film, and evaluate its service life and stability.
2023 Post Sprint Race Based on the above methods, the waterproof and breathable membrane of the microphone can be comprehensively tested and evaluated to ensure that it has good waterproof, breathable performance, stability and durability.
