Segmented damping plates reduce ringing time and electrical noise for shorter ultrasonic distance measurements.
Coil springs with specific winding directions create a rotational bias force that suppresses noise from rotational vibrations in thin mobile devices.
Foamed silicone resin merges filler and acoustic absorbent functions to seal the cavity, reducing component count and manufacturing complexity.
Segmented coils and opposing magnets create superposed driving force, reducing response time in portable devices.
Alternating between light transmissive body and flange portion vibration modes prevents optical axis displacement while removing water droplets.
Equal-mass working jackets on a soil preparation roller ensure constant system weight, resolving the trade-off between adaptability and compaction efficiency.
