Abstract

L'invention concerne les résonateurs à quartz. Le résonateur de l'invention comprend une lame de quartz en forme de diapason qui comporte non seulement des électrodes 17, 18 sur ses faces supérieure et inférieure, mais également des électrodes 15, 16' sur ses faces latérales. Les electrodes des faces latérales améliorent considérablement les caractéristiques du résonateur, sans compliquer notablement sa fabrication par photogravure. Application aux montres électroniques.
