Abstract: The invention relates to a sound-reproducing transducer (60) connected to a printed circuit (50). This transducer (60) has the shape of a hollow cylinder whose cylindrical wall (66) delimits two circular faces, one front face (66c) and one rear face (66d) that are opposed and planar. The transducer (60) comprises at least one diaphragm (64) that makes it possible to convert electric signals into sound waves and conversely. This diaphragm (64) is a circular membrane parallel to the front face (66c) and rear face (66d) of the transducer (60). The diaphragm (64) delimits two distinct volumes in the transducer (60), the first volume being bordered on one side by the circular face (66c) of the transducer (60) and on the other by the diaphragm (64) while forming a front acoustic cavity (61), and the second volume being bordered on one side by the circular face (66d) of the transducer (60) and on the other by the diaphragm (64) while forming a rear acoustic cavity (62).

Abstract: A method for personalizing the working of a portable communication device (1) including the steps of an initialization step (A0) during which multimedia content data files are stored (A01) in a removable memory (18) of said portable communication device, and personalization parameters for controlling peripherals (2, 17) of said device are set (A02) with software links to at least some of said data files; and further including prior to removal of said removable memory (18), a step (A03) for creating a table including said software links, and a step (A2) for copying, according to said table, said data files for which software links exist or at least a transformation of said data files, from said removable memory (18) to an internal memory (7) of said portable communication device.

Abstract: A method for capturing an image with an electronic handheld device (1) equipped with a camera unit (2) and capture means (3) for triggering an image capture, said electronic handheld device (1) further comprising power supplying means (4) connected to said camera unit, and at least one additional component (5) also connected to said power supplying means (4) through a DC/DC converter (11), said method comprising a first step (B) for detecting actuation of capture means (3), and a second step (C) for capturing image once actuation of capture means has been detected. According to the invention, said method further comprises an intermediate step (D) for switching said DC/DC converter (11) off for at least the duration of the second step (C).
