摘要

The mechanical, non electronic device comprises a massive body. A diaphragm is supported in a housing (1), and a natural resonance of a device is doped at the body. A hose is mounted at the housing, where the resonance is transmitted and branched in two wires. An end piece is inserted into a lug on two hose ends. An elastic u-shaped metal holder fixes the end piece in the lug with a moderate pressure.
