A soundproof speaker is a device specifically designed to test the noise of electronic components. It can provide a low-noise environment for more accurate measurement and evaluation of the noise level of electronic components. The following are some key points about testing electronic component noise with a static speaker:
 
Characteristics of soundproof speakers
 
1. Low noise environment: Static speakers are usually designed to have very low background noise, which helps improve the accuracy of testing.
2. Sound insulation performance: The soundproof box has good sound insulation performance, which can effectively isolate external noise and ensure the purity of the testing environment.
3. Diverse sizes: There are multiple sizes of speakers to choose from to meet the testing needs of electronic components of different sizes.
4. Internal configuration: Static speakers are usually equipped with power interfaces, testing brackets, etc., which facilitate various testing operations.
 
testing procedure
 
1. Preparation stage:
-Ensure that the soundproof speaker is in good working condition.
-Prepare the electronic components and testing instruments to be tested.
 
2. Install electronic components:
-Place the electronic components to be tested on the testing bracket inside the soundproof box.
-Connect the power supply and testing equipment.
 
3. Turn off the speaker:
-Close the door of the soundproof speaker, ensure good sealing, and avoid external noise interference.
 
4. Conduct testing:
-Start the testing instrument and begin measuring the noise level of electronic components.
-Record test data to ensure its accuracy and completeness.
 
5. Data analysis:
-Analyze the test data and evaluate the noise performance of electronic components.
-Based on the test results, propose improvement measures or optimization plans.
 
Application scenarios
 
Silent speakers are widely used for noise testing of various electronic components, including but not limited to:
 
-Speaker: Test the acoustic performance and noise level of the speaker.
-Microphone: Evaluate the sensitivity and noise characteristics of the microphone.
-Small motor: Measure the operating noise and vibration of small motors.
-Test the noise performance of other electronic components such as transformers, capacitors, etc. during operation.
