Tune selection mechanism for a chiming timepiece
10031482 · 2018-07-24 · ·

Chiming timepiece comprising a movement and an acoustic indication mechanism with a control mechanism controlling the performance of a chime or tune by setting control lifts in motion that each actuate a hammer arranged to strike a gong, and each control lift is releasable between a released position, in which it is decoupled from the control mechanism, and a resting position, in which it is able to be driven for actuation of the hammer by the control mechanism that is set in motion by the movement, or by a manual actuator, and tune selection devices for the selection of at least one particular chime or tune are controlled by this movement or by a manual selector and control the passage of each control lift from its released position to its resting position or vice versa.

Mechanism for the magnetic actuation of timepiece striking mechanisms

A watch including a timepiece striking mechanism, including a drive mechanism for driving and controlling the striking mechanism to operate at least one rigid hammer, movable between a first winding position and a second striking position, the hammer being arranged to strike a gong in the second striking position, this hammer including at least one magnetized portion arranged to cooperate with at least one actuator arranged to be driven in motion by the drive mechanism, the actuator including an alternating series of first areas and second areas with different magnetic field characteristics from each other, to whose influence the magnetized portion is successively subjected on order to trigger, as the case may be, the winding of the hammer or the striking of the hammer on the gong.

Timepiece comprising a vibration-amplifying device

Disclosed is a timepiece including a case, a movement and a vibration-generating device intended to produce a sound, the latter two accommodated in the case, a device for amplifying the vibrations from the vibration-generating device, and a membrane receiving the amplified vibrations and generating a sound to outside the timepiece. The vibration-amplifying device includes a lever pivotally mounted on a support in a pivoting plane non-parallel to the plane of the membrane and actuated by a transmission member cooperating with the vibration-generating device to transmit the vibrations to the lever, the lever being integral with the membrane at least translationally in the pivoting plane so a movement of the transmission member, generated by vibration of the transmission member linked to the vibration-generating device and transmitted to the membrane by way of the lever actuated by the transmission member, generates an amplified movement of the membrane for an amplified sound.
