Title
(EN) NOISE SENSING BOBBIN-COIL ASSEMBLY FOR AMPLIFIED STRINGED MUSICAL INSTRUMENT PICKUPS
(FR) ENSEMBLE BOBINE ET BOBINAGE DE DETECTION DE BRUIT POUR CAPTEURS D'INSTRUMENTS DE MUSIQUE A CORDES AMPLIFIES
Abstract
(EN)
A pickup transducer for a stringed musical instrument (20) includes a noise cancelling coil (25) wound on a bobbin (21). This bobbin is adapted to resist eddy currents thereby allowing fewer turns to be used which in turn reduces undesirable interaction with the musical instrument pickup (12). The noise sensing bobbin-coil assembly (21 to 28) includes a core (22) formed of magnetically permeable material which either minimises eddy current losses or is configured to minimise eddy currents, and a coil of copper wire (25) formed about said core for the purpose of generating a noise cancelling voltage.
(FR)
Transducteur de capteur pour un instrument de musique (20) à cordes, qui comporte un bobinage (25) de suppression de bruit enroulé sur une bobine (21). Cette bobine est adaptée pour résister aux courants de Foucault, ce qui permet l'utilisation d'un nombre inférieur de spires et réduit par conséquent l'interaction indésirable avec le capteur (12) de l'instrument de musique. L'ensemble (21-28) bobine et bobinage de détection de bruit comporte une partie centrale (22) formée d'une matière à perméabilité magnétique qui soit réduit à un minimum les pertes par courants de Foucault, soit est configuré pour réduire à un minimum les courants de Foucault, et un bobinage en fil de cuivre (25) formé autour de ladite partie centrale pour produire une tension de suppression de bruit.
