20140355398 | STRIKING MECHANISM PROVIDED WITH A MEANS OF SELECTING THE MODE OF VIBRATION OF A GONG - The striking mechanism ( | 12-04-2014 |
20140366705 | METHOD FOR ADJUSTING THE VIBRATION FREQUENCY RANGE OF A SOUND PRODUCING DEVICE WITH VIBRATING TONGUES - The invention concerns a method for adjusting the vibration frequency range of a sound producing device with vibrating tongues. The device includes an assembly formed of a comb extended by at least one vibrating tongue, said comb having at least one hole for the securing thereof to a support by means of a support jaw and of a tightening element traversing the support jaw and the hole in the aforecited comb. According to the method, the frequency range is adjusted by reducing the free length of the vibrating tongue or tongues by the localised clamping of said tongues between the support jaw and a local counter-support. | 12-18-2014 |
20150013460 | METHOD FOR CHECKING THE IDENTITY OF A MECHANICAL WATCH MOVEMENT - The mechanical movement includes a checking device which is a passive indicator element. The passive element is fixed to a fixed support portion of the mechanical movement. The passive element may be a strip or a plate fixed to the fixed support portion of a regulating member and configured to vibrate according to one or more clearly defined vibration frequency components following the vibration of the mechanical movement. The vibration frequency components of the strip or plate define an acoustic signature specific to the timepiece to allow the authenticity of the timepiece to be determined by a measurement of the acoustic signature using an acoustic measuring system. | 01-15-2015 |
20150160615 | WATCH CANNON-PINION - Watch cannon-pinion including a first bore for receiving a pivot-shank including, on either side of a recess, a first shoulder and a second shoulder. | 06-11-2015 |
20150160616 | OPTIMISED STRIKING MECHANISM DISC-VIBRATION PLATE FOR A TIMEPIECE - A disc-vibration plate assembly for a musical or striking timepiece, including at least one disc rotating about an axis and provided with pins projecting substantially parallel to this axis, and arranged to cooperate with strips comprised in at least one vibration plate of this assembly, each pin including an actuation surface arranged to cooperate with a complementary receiving surface of a corresponding strip and the section of these strips of the vibration plate gradually increases from the shortest strip which is the highest pitched, to the longest strip which is the lowest pitched. | 06-11-2015 |
20150160617 | ACOUSTIC RADIATING MEMBRANE FOR A MUSICAL WATCH - The acoustic radiating membrane is provided to equip a musical watch or a striking watch. The dome-shaped membrane comprises an active central portion, a lateral wall and a peripheral edge portion for holding the membrane in a watch case. The central part is configured in a convex shape or a conical shape and with dimensions devised to amplify a first vibration mode of one or more notes within a frequency range of between 500 Hz and 3.5 kHz. | 06-11-2015 |
20150160618 | ACOUSTIC RADIATING MEMBRANE FOR A MUSICAL WATCH - The acoustic radiating membrane is provided to equip a musical watch or a striking watch. The dome-shaped membrane comprises an active central portion, a lateral wall and a peripheral edge portion for holding the membrane in a watch case. The central portion includes a central base connected by connecting elements to a peripheral ring, the central base, the connecting elements and the peripheral ring being of dimensions determined to amplify a first vibration mode of one or more notes in a frequency range from 500 Hz to 3.5 kHz. | 06-11-2015 |
