AI Technical Summary
Technical Problem
Miniaturized sound transducer devices, such as MEMS microphones and speakers, are vulnerable to environmental elements like fluids and particulate matter due to their small form factor and open sound ports, which can lead to damage and reduced performance.
Method used
A sound transducer device with a multilayer component board and a mesh structure covering the sound port, providing an environmental barrier to protect the suspended membrane structure from environmental elements while maintaining sound performance.
Benefits of technology
The mesh structure effectively prevents damage from environmental elements, ensuring the integrity and performance of the MEMS sound transducer devices without increasing physical volume or component count.
