A striking or musical watch with an acoustic waveguide arrangement. The striking or musical watch (1) includes an at least partially flexible waveguide (2) secured to a fixed part (8) inside the watch to guide the acoustic waves generated by a first portion (2′) of the at least partially flexible waveguide towards a radiating element. The radiating element can include a watch crystal (3) connected to a bezel (5) and a membrane (4) for connecting the bezel to a middle part (6) of a watch case. The flexible waveguide is configured to change the direction of acoustic vibration from the first portion to the radiating element.

A musical watch case including a case middle with surfaces for receiving and supporting a cover with a bezel, and a casing ring, and supporting at least one gong with a resonant part distinct from the walls of the case middle, which supports the cover via distinct and remote lugs included in the bezel or the case middle and which are arranged to allow vibration of the cover, and form, with at least one gasket, the only direct contacts between the bezel and the case middle, which includes, around an annular wall defining an inner chamber around the casing ring, and around all the other these lugs, a resonator ring integral with the case middle distant at every point from the bezel and from the lugs, forming with this wall an external radiating cavity.

A musical watch case including a case middle with surfaces receiving and supporting a cover with a bezel, or a case back, and a casing ring, the case including at least one gong fixed to the case middle with a resonant part distinct from the walls of the case middle, which supports the cover via lugs included in the bezel or the case middle and which are arranged to allow vibration of the cover assembly at frequencies from 4 kHz to 6 kHz, these distinct and distant lugs forming, with at least one gasket, the only direct contacts between the bezel and the case middle, between which each lug includes a thin, elastic, median strip, more flexible than its solid distal end, and of smaller thickness than the smallest cross-section of these gongs.

An assembly includes a plurality of gongs, which are connected to at least one gong carrier for a striking mechanism of a watch. Some gongs each connected to a respective gong carrier and a group of gongs connected to one and the same gong carrier are produced with materials different from each other.

An arrangement for the holding and vibration transmission of an acoustic radiating membrane (10) in a striking or musical watch (1) case (2). The case includes at least one crystal (3) mounted on a middle (4) and a back (5) mounted on a side opposite the middle. The acoustic radiating membrane is held in a portion of the watch case, such as the middle by at least one connection part (12) disposed between a peripheral rim of the membrane or an edge element (11) of the membrane and the middle by acting for the holding of the membrane in a direction parallel to the plane of the watch. The connection part may be a screw screwed into a threaded opening (14) of the middle and coming into contact with the edge element of the membrane.

A striking or musical watch with an acoustic waveguide arrangement. The striking or musical watch (1) includes an at least partially flexible waveguide (2) secured to a fixed part (8) inside the watch to guide the acoustic waves generated by a first portion (2) of the at least partially flexible waveguide towards a radiating element. The radiating element can include a watch crystal (3) connected to a bezel (5) and a membrane (4) for connecting the bezel to a middle part (6) of a watch case. The flexible waveguide is configured to change the direction of acoustic vibration from the first portion to the radiating element.

A resonant member for a striking mechanism of a watch or of a music box includes at least one resonant part, such as one or more gongs, arranged to vibrate and resonate once activated, and an attachment part. The resonant part and/or the attachment part is made from an alloy of tungsten or tantalum or rhodium or hafnium with more than 51% of tungsten or tantalum or rhodium or hafnium in the alloy.

A striking watch is provided with an acoustic radiating membrane made of metallic material or amorphous metal. The membrane takes the form of a loop with walls of a certain thickness to be connected by a first edge portion to a middle part of a watch case and by a second edge portion to a bezel fixed to a watch crystal. The bezel connected to crystal is movable with respect to the case middle via the membrane during the vibration of membrane once a sound is generated by a watch striking mechanism in the watch case. The membrane is configured with a wall of a specific thickness in an active region dependent on the mass of the bezel connected to the crystal, to obtain a frequency f.sub.0 of a first vibration mode.

The gong is made with a wire or a strip having an atypical shape for a watch striking mechanism. The gong includes a rectilinear part connected to a curved part. The rectilinear part and/or the curved part are connected to the same gong-carrier. The gong includes several notches made at defined geometric points on a portion of the length of the gong to adapt the natural vibration frequencies within an audible range between 1 kHz and 5 kHz, so that the sound produced by the vibrating gong is harmonious.

A musical watch case including a case middle with surfaces for receiving and supporting a cover with a bezel, and a casing ring, and supporting at least one gong with a resonant part distinct from the walls of the case middle, which supports the cover via distinct and remote lugs included in the bezel or the case middle and which are arranged to allow vibration of the cover, and form, with at least one gasket, the only direct contacts between the bezel and the case middle, which includes, around an annular wall defining an inner chamber around the casing ring, and around all the other these lugs, a resonator ring integral with the case middle distant at every point from the bezel and from the lugs, forming with this wall an external radiating cavity.
