Radio Frequency Testing

In recent years, with the continuous improvement of people's pursuit of quality of life, headphones are no longer just audio playback devices, but have become loyal companions for sports, fitness, and outdoor activities. In such usage scenarios, the protective performance of headphone products becomes particularly important. IP68, as one of the highest protection levels, is gradually becoming a standard feature for high-end headphones.

1、 Gain a deeper understanding of the meaning of IP68 rating

The first digit "6" of the IP code indicates the highest level of dust resistance. The product casing that reaches this level can achieve complete dust barrier, even when used in dusty environments, there is no need to worry about dust entering the interior and affecting component performance.

The second digit "8" represents the high standard of waterproof performance. Normally, the test will place the product at a depth of at least 1 meter below the water surface and maintain a soaking time of at least 30 minutes. It should be noted that the specific testing parameters should be based on the clear definition in the product specification sheet.
 

2、 Preparation before testing

Before officially starting the testing, comprehensive preparation work is required. Firstly, it is necessary to confirm the integrity of the test sample, and all interfaces should be sealed according to regulations. For example, key parts such as charging contacts and sound outlets require special protective measures.
 

3、 Detailed explanation of testing process

Dust prevention testing is usually conducted in a dedicated dust testing chamber. During testing, the sample will be continuously exposed to a sealed space filled with fine talcum powder for 8 hours. After the test is completed, open the casing for inspection, and there should be no obvious dust adhesion on the surfaces of all internal components.
 

4、 Key steps in the testing process

Special attention should be paid to the setting of pressure parameters in the waterproof testing process. Generally speaking, the test pressure will be slightly higher than the static water pressure to simulate the real usage environment.
 

During the testing process, it is necessary to closely monitor the changes in the state of the sample. Any minor anomaly may indicate potential protective deficiencies.
 

3、 Detailed explanation of testing process

The dust prevention testing process requires strict control of dust concentration and environmental temperature and humidity. During the testing process, attention should be paid to observing whether there are any abnormal changes in the appearance of the sample.
 

4、 Key steps in the testing process
 

The focus of waterproof testing is to test the sealing performance of the shell. During the testing period, a constant water pressure environment needs to be maintained.
 

5、 Common problems and solutions

In the actual testing process, the most common problems mainly focus on sealing performance. This may be potentially related to factors such as the thickness, hardness, and structural fit gap of the silicone sleeve.

6、 Processing steps after testing

After the test is completed, the sample should be taken out immediately and the surface should be gently wiped with a dry, lint free cloth. Subsequently, functional testing will be conducted to ensure that all aspects of the product's performance are normal.
 

7、 Professional advice
 

It is recommended to consider protective performance as an important factor in the product design phase. Excellent structural design is often more important than later improvements.
 

In practical operation, there are several key points that need special attention: ensuring that all interfaces are sealed properly; Strictly execute the test according to the predetermined parameters; Complete recording of the entire testing process.
 

8、 Practical Experience Sharing

Based on past test cases, we have found several noteworthy details: the dust screen of the sound outlet requires a multi-layer composite structure to achieve the desired effect.

Special attention should be paid to the stability of pressure changes during waterproof testing. Sudden pressure fluctuations may have an impact on the test results.
 

9、 The significance of testing
 

Through IP68 rated headphone products, it can maintain good working condition in various high-intensity use scenarios such as swimming training and off-road running.
 

10、 Summary of Technical Points
 

It should be emphasized that different types of headphones require corresponding testing methods during testing. For example, true wireless earphones require comprehensive testing of the charging case and left and right earphones separately.
 

11、 Precautions
 

It should be noted that even products that have passed the IP68 test require attention to maintenance and upkeep during daily use.
 

12、 Summary and Induction
 

Overall, IP68 testing for headphone products is a system engineering that requires cooperation from multiple parties. From the initial design concept to the final product output, every step needs to be strictly controlled.
