Method for broadcasting an acoustic signal

A watch comprising:

• a sound interface (3) including a plurality of piezoelectric elements (4) mounted on at least one deformable support element (9), said plurality of piezoelectric elements (4) being separately controllable, and
• a processing unit (2),
• said processing unit (2) being connected to said sound interface (3) and configured to:
• identify an event relating to a function of the watch (1), the event including an activation of an operation mode of the watch,
• send a configuration signal relating to said identified event to the sound interface (3), the configuration signal comprises a design criterion relating to said identified event and information used to separately control each of the piezoelectric elements (4) of the sound interface (3), such that said plurality of piezoelectric elements (4) and said at least one deformable support element (9) produce a sound of a mechanical watch movement,
• wherein the design criterion comprises operating data of the sound interface (3) comprising at least one vibration frequency and at least one vibration amplitude, the at least one vibration frequency and the at least one vibration amplitude being defined for each piezoelectric element (4) constituting said interface (3),
• wherein the plurality of piezoelectric elements (4) and said at least one deformable support element (9) are configured to produce a caress touch message able to be broadcast to a wearer of the watch, and
• wherein the caress touch message includes the production of a contour of a graphical representation in a tactile manner, and wherein the graphical representation includes at least one of a pattern, a symbol, a letter and a figure.

A non-transitory computer readable medium storing code instructions, which, when executed by at least one processor, cause the at least one processor to:

• identify an event relating to a function of a watch (1), the event being an activation of an operation mode of the watch,
• send a configuration signal relating to said identified event to a sound interface (3) of the watch (1), the sound interface (3) comprising a plurality of piezoelectric elements (4) mounted on at least one deformable support element (9), said plurality of piezoelectric elements (4) being separately controllable, and said plurality of piezoelectric elements (4) and said at least one deformable support element (9) together being configured to produce a sound,
• cause the plurality of piezoelectric elements (4) and said at least one deformable support element (9) to produce a sound of a mechanical watch movement in accordance with the operation mode of the watch, and
• cause the plurality of piezoelectric elements (4) and said at least one deformable support element (9) to produce a caress touch message
• wherein the sending of the configuration signal comprises selecting a design criterion for the configuration signal relating to said identified event and information used to separately control each of the piezoelectric elements (4) of the sound interface (3) such that the piezoelectric elements (4) are able to provide at least one of a sound able to be broadcast to the wearer,
• wherein the design criterion comprises operating data of the sound interface (3) comprising at least one vibration frequency and at least one vibration amplitude, the at least one vibration frequency and the at least one vibration amplitude being defined for each piezoelectric element (4) constituting said interface (3), and
• wherein the touch message includes the production of a contour of a graphical representation in a tactile manner, and wherein the graphical representation includes at least one of a pattern, a symbol, a letter and a figure.
