Embodiment Construction

[0017] In the following description, all components of a watch striking mechanism known in the art will only be briefly described. Only the means for selecting at least one mode of vibration of the gong or gongs will be referred to, without detailed reference to the hammer and its arrangement in the mechanism for striking the gong.

[0018] figure 1 Diagram showing the deflection curve of a gong of length L, for example fixed at one of its ends to a gong support fixed to an inner watch part, for example on a plate . figure 1 Various modes of vibration of the gong are shown after hammer impact has occurred. In the absence of vibration mode selection means, the gong tends to vibrate in a combination of a first vibration mode denoted n=1, a second vibration mode denoted n=2 and a third vibration mode denoted n=3. Several other vibration modes can also be combined with the first three vibration modes, but these are not shown in order to avoid overloading the figure.

Abstract

The striking mechanism (1) particularly for a watch, includes at least one gong (3) fixed to a gong-carrier (2), at least one hammer for striking the gong at predetermined times, and a means of selecting at least one mode of vibration of the gong. The selection means includes at least one selector element (4) arranged in contact on a part of the gong and held on a vibration node of a mode of vibration of the gong to be selected so as to block other modes of vibration. The selector element can be moved on the gong by a mechanical or magnetic means of movement.

Description

technical field [0001] The invention relates to a striking mechanism provided with means for selecting at least one mode of vibration of a gong or gongs. The striking mechanism, in particular for watches, also comprises at least one gong fixed to the gong support and at least one hammer for striking the gong at a predetermined time. Background technique [0002] In the field of watchmaking, traditional structures are used to manufacture movements provided with striking mechanisms, such as minute repeaters. For this type of embodiment, the gong used is a wire, which can be round or straight. A circular wire can be set around the movement inside the frame of the watch. The gong is fixed on at least one gong support, which in turn is fixed on the machine plate of the watch. The gong vibrations are generated by the impact of at least one hammer, usually adjacent to the gong support. This vibration is made up of several natural frequencies, the number and intensity of which -...
