Abstract

La présente invention concerne un tambour électronique apte à détecter une frappe de cercle en un court laps de temps tout en étant moins affecté par des vibrations provoquées par autre chose que la frappe de cercle. Un tambour électronique (100) selon l'invention comporte un support de capteur (120) et un couvercle (130) disposés dans une coque cylindrique (103) qui maintient une tête (101). Le support de capteur (120) est constitué d'un matériau métallique sous forme d'anneau de plaque plat. Le couvercle (130) est formé d'un seul tenant avec un support en forme d'anneau de plaque plat (131) s'étendant parallèlement au support de capteur (120) et une paroi latérale (132) se courbant et s'étendant de la périphérie interne du support (131) au support de capteur (120). Le support de capteur (120) et le couvercle (130) sont reliés à une patte (104) disposée sur la surface périphérique externe de la coque (103). La patte (104) est reliée à un cercle (106) afin de presser la tête (101) contre la coque (103) par l'intermédiaire d'un boulon de tension (107).
