A sound production device is designed to be arranged in a case of a timepiece, in association with a timepiece movement comprising a chiming or alarm mechanism, and comprises: at least one external connecting member for assembling the sound production device to the timepiece case, a sound producing member comprising a heel carrying at least one vibrating member made in one piece with said heel, a damping member, assembled to the sound producing member and designed to form an assembly interface between the latter and the timepiece movement, and one or more internal connecting members arranged solely on the damping member and designed to assemble the sound production device to the timepiece movement.

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.

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.

A control device is disclosed, which comprises: a lever movable between a rest position and a triggering position, a spring arranged to return the lever in its rest position, an actuating member movable between a neutral position and an actuating position in which it actuates a watch mechanism, a mechanical energy storage member interposed between the lever and the actuating member in such a way that it is charged when the lever moves towards its triggering position, and can be discharged when the lever reaches its triggering position by moving the actuating member towards its actuating position, the device comprising a locking member intended to release the actuating member only when the lever reaches its triggering position.
