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). The invention is characterized in that the cylindrical wall (66) of the transducer (60) has at least one perforation (72, 74, 76, 77, 78).

A method for personalizing the working of a portable communication device (1) including the steps of an initialization step (A.sub.0) during which multimedia content data files are stored (A.sub.01) in a removable memory (18) of said portable communication device, and personalization parameters for controlling peripherals (2, 17) of said device are set (A.sub.02) with software links to at least some of said data files; and further including prior to removal of said removable memory (18), a step (A.sub.03) for creating a table including said software links, and a step (A.sub.2) 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.
