AUDIO MODULES WITH FINS TO REDUCE ACOUSTIC NOISE DUE TO AIRFLOW - A simplified explanation of the abstract
This abstract first appeared for US patent application 17895984 titled 'AUDIO MODULES WITH FINS TO REDUCE ACOUSTIC NOISE DUE TO AIRFLOW
Simplified Explanation
- Acoustic module with integrated fins to reduce noise - Fins divert airflow caused by pressure changes from oscillating diaphragm - More uniform airflow distribution leads to lower peak velocity and less noise - Fins may have curved or crescent shape and spaced in a certain manner
Potential Applications
- HVAC systems - Automotive engines - Industrial machinery
Problems Solved
- Reduction of acoustic noise - Improved airflow distribution
Benefits
- Lower peak velocity - Less unwanted noise - Improved overall performance of the acoustic module
Original Abstract Submitted
Implementations of the subject technology provide an acoustic module with fins integrated within the acoustic module to reduce acoustic noise. Airflow caused by pressure changes due to an oscillating diaphragm can be diverted by the fins within the acoustic module. The diverted airflow provide a more uniform airflow distribution within the acoustic module, which leads to a lower peak velocity and less unwanted noise. Fins may include a curved or crescent shape and may be spaced in a certain manner to divert the airflow.
