Abstract: L’invention se rapporte à un résonateur (1) thermocompensé comportant un corps utilisé en déformation, l’âme (8) du corps étant formé par de la céramique. Selon l’invention, au moins une partie du corps comporte au moins un revêtement (2, 4) dont les variations du module d’Young en fonction de la température (CTE) sont de signe opposé à celles (CTE) de la céramique utilisée pour l’âme (8) afin de permettre audit résonateur d’avoir une variation de fréquence en fonction de la température au moins au premier ordre (α, &bgr;) sensiblement nulle. L’invention concerne le domaine des pièces d’horlogerie.

Abstract: The resonator (1) has a low frequency resonator (2) coupled with a high frequency resonator (3). The low and high frequency resonators have inertia masses associated with balance springs (5, 7), respectively. Another balance spring (8) is arranged between the inertia masses to couple the low frequency and high frequency resonators. The inertia masses are respectively formed by balances (4, 6). The resonators are placed coaxially inside a timepiece.

Abstract: The resonator has a low frequency hairspring (1) and a high frequency tuning fork (2) connected mechanically in a permanent manner. The hairspring and the tuning fork are made of identical or different material e.g. metal, alloy or amorphous material, monocrystaline or polycrystalline material such as glass, quartz and silicon. The tuning fork comprising two arms (4, 6) that are connected by a steady pin (8).

Abstract: The collet has a plate (1) comprising an opening (3) for the fixation on an axle (5) of a balance of a balance-hairspring adjusting system in a mechanical clock movement, where the collet is formed of glass, quartz or silicon. A securing unit secures a hairspring (7) at a determined junction point of the collet. The collet has an asymmetric contour (9), which follows, from a place to place at a constant distance, the contour of a turn (11) of the curve at the interior. Recesses (13) reposition the center of gravity of the collet or collet-hairspring assembly on the balance axle.
