    Description
    BACKGROUND OF THE INVENTION [0001] The invention relates to a resonant organ for a timepiece bell or a music box, comprising at least one resonant part arranged to vibrate and resonate under the action of percussion or pinching.
    The invention also relates to a watch, or a music box, comprising a ringing and / or wake-up and / or melody game mechanism, comprising percussion or pinching means arranged to strike or pinch at least Such a resonant member.
    BACKGROUND OF THE INVENTION [0003] Bells or musical boxes must emit, in a chamber of small volume, a sound that is both pure and powerful. Good results are obtained with stamps or gongs of precious metal, especially gold. However, such components, which are superior to bronze or steel stamps, are expensive. The search for improvements in resonance and sound purity requires a number of material tests, which must also satisfy the weather-resistant condition of atmospheric resistance and have sufficient mechanical qualities to withstand And in particular to tests of watches under accelerations of 5000 g. SUMMARY OF THE INVENTION [0004] To this end, the invention relates to a resonant member according to claim 1.
    [0005] L’ invention concerne encore une montre, ou une boîte à musique, comportant un mécanisme de sonnerie ou/et de réveil ou/et de jeu de mélodie, comportant des moyens de percussion ou de pincement agencés pour percuter ou pincer au moins un tel organe résonant.
    BRIEF DESCRIPTION OF THE DRAWINGS Other characteristics and advantages of the invention will appear on reading the following detailed description, with reference to the accompanying drawings, in which: FIG. 1 shows, in a schematic manner, a watch stamp according to the invention; FIG. 2 shows, in the form of a block diagram, a striking mechanism comprising at least one such resonant member; FIG. 3 shows, in the form of a block diagram, a wake-up mechanism comprising at least one such resonant member; FIG. 4 shows, in the form of a block diagram, a melody play mechanism, comprising at least one such resonant member; FIG. 5 shows, in the form of a block diagram, a sound mechanism comprising at least one physical data sensor and means for triggering a safety sound signal, Comprising at least one such resonant member; FIG. 6 shows, in the form of a block diagram, a watch comprising a mechanism provided with a resonant member according to the invention; FIG. 7 shows, in the form of a block diagram, a music box comprising a mechanism provided with a resonant member according to the invention.
    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention relates to a resonant member 1 for a timepiece or a music box, comprising at least one resonant part 2 arranged to vibrate and resonate under the action of percussion or d Pinching, or friction by bow, or the like.
    [0008] According to the invention, at least one resonant part 2 that it comprises is made of a ceramic material.
    More particularly, this resonant member 1 comprises a fastening portion 3, which is made integral with this resonant portion 2 of the same ceramic material.
    [0010] More particularly, this resonant member 1 is one-piece and entirely made of this ceramic material.
