ActiVib

Product catalog summary

Introduction
The document introduces the ActiVib bearing, a precision engineering innovation by MPS Micro Precision Systems AG, designed to reduce sound vibrations in automatic watch movements.

Specifications
The ActiVib bearing integrates a built-in vibrations damper made from a specially developed elastomeric polymer. This design effectively filters sound vibrations generated by the ball bearing, reducing them by approximately 10 dBA.

Functionality
In automatic watches, the oscillating mass rotates using a ball bearing, which generates acoustic waves. These waves propagate through hard materials like metals, causing sound vibrations to spread within the watch case. The ActiVib bearing addresses this by incorporating a damper that mitigates the transmission of these vibrations to other components.

Testing and Results
Laboratory tests confirm that the ActiVib bearing achieves a significant reduction in sound vibrations, demonstrating its effectiveness in enhancing the acoustic performance of watch movements.

Conclusion
The ActiVib bearing represents a significant advancement in reducing noise in precision watch movements, offering a practical solution for improving the acoustic environment within watch cases.
