<p>The beater has a mobile mass (1) displaced linearly in a reciprocating motion along a given displacement direction. A guiding unit forms a slide and guides the mass. The guiding unit comprises two connectors with a degree of freedom along the axis. A support comprises two ferromagnetic straight cylindrical cores (21, 22), and the mass comprises a reel, and is traversed by the cores. A suspension unit (3) consists of an adhered elastomer element. The mass is mounted free in translation on the cores.</p> |
