Electromagnetic non-acoustic alarm with electromagnetic motor having movable and stationary circuits with resilient connection elements

A non-acoustic alarm for a portable object comprising:

• an electromagnetic motor configured to be electrically controlled in order to generate a vibratory effect, wherein the electromagnetic motor comprises a movable magnetic circuit and a stationary magnetic circuit, said movable magnetic circuit comprising a coil, a ferromagnetic core coupled to a magnetic cage forming an extension of the ferromagnetic core, a magnetic assembly of said movable magnetic circuit constituting a movable magnetic mass of said non-acoustic alarm to generate said vibratory effect;
• and
• resilient connection elements resiliently connecting the movable magnetic circuit to the stationary magnetic circuit, the resilient connection elements being shaped to guide and ensure that the movable magnetic circuit undergoes a linear, or quasi-linear, oscillatory motion during the electrical control of the electromagnetic motor,
• wherein the resilient connection elements belong to a support that receives the stationary magnetic circuit and the movable magnetic circuit, and
• wherein the support comprises a stationary part receiving the stationary magnetic circuit and a movable part receiving the movable magnetic circuit, the resilient connection elements mechanically connecting the movable part of the support to the stationary part thereof, while guiding the movable magnetic circuit and ensuring that the movable magnetic circuit undergoes the linear, or quasi-linear, oscillatory motion during the electrical control of the electromagnetic motor.
