Abstract
A vibrating module for generating a mainly non-audible alert signal comprises a vibrating mass supported by at least one spring and having a weight and a magnet. A drive coil is supported by a coil frame for placing the vibrating mass in a continuous reciprocating motion close to a resonant frequency determined by the vibrating mass and the spring. An electrical signal supplying device supplies an electrical signal to the drive coil to vibrate the vibrating mass in a linear reciprocating motion. A vibration transmitting device transmits the vibration of the vibrating mass via the spring to an outer portion of the vibrating module to generate a mainly non-audible alert signal.
