Vibration sensor device, comprises cone-shaped protrusions extending from inner periphery of hollow sphere casing and ball received in casing contacts three protrusions

摘要

The device comprises a hollow sphere casing (2) having cone-shaped protrusions (11,12) extending from an inner periphery of the casing. A ball (13) is received in the casing and located in contact with the three protrusions (11,11,12). The protrusions that contact the ball is located in X, Y, Z axles. The ball freely rolls and contacts different protrusions when the casing senses vibration.
