A timepiece includes a case containing a movement, at least one device for generating vibrations intended to produce at least one sound, and at least one device for amplifying the vibrations generated by the vibration-generating device. The device for amplifying the vibrations includes a lever linked to a support by an articulation about a single axis of rotation and arranged to be actuated by a transmission member cooperating with the vibration-generating device to transmit the vibrations to the lever. The device for amplifying the vibrations includes at least one plate arranged to cooperate with the lever in order to be displaced according to a vibration movement, the plate being housed in the case so as to form a free space on the periphery of the plate over at least 70%, preferably at least 80%, of the perimeter of the plate.

Timepiece comprising a vibration-amplifying device

Disclosed is a mechanical wristwatch including a case having a middle, a back cover and a bezel, a vibration-generating device for generating vibrations which are intended to produce at least one sound, which is accommodated in the case, a vibration-amplifying for amplifying the vibrations generated by the vibration-generating device, and a membrane arranged to receive the amplified vibrations and generate a sound from the inside to the outside of the wristwatch. The vibration-generating device is a rotary element having a reading surface including at least one groove arranged to generate sounds. The wristwatch also includes a unit for rotationally driving the rotary element, an actuator for such unit, and a transmission member arranged to cooperate with the rotary element to transmit, to the vibration-amplifying device, the vibrations generated by the groove during rotational movement of the rotary element.

Sound-generating timepiece

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.
