Abstract (en)
[origin: WO2019030438A1] This method for manufacturing a device for locating an impact comprising an interactive surface (12) having a front face for receiving an impact and at least three transducers (PT) that need to be distributed and attached against the front face (A) or a rear face (B) of the interactive surface (12), comprises the following steps: determining (102) a central positioning point (C) for each transducer (PT) on the front face (A) or rear face (B) of the interactive surface (12); attaching (102) each transducer (PT), via the lower conductive layer (28) of same forming a first electrode, around the central positioning point (C) of same. The method further comprises, following the attachment (102) of each transducer (PT), a step of machining (104) the free upper conductive layer (26) of at least one of the transducers (PT), using a machine tool (32), at least as far as a piezoelectric intermediate layer (24) of this transducer (PT), in order to form a second electrode (34) of this transducer (PT), centring it around the central positioning point (C) of same.
