The invention relates to a method for reproducing a moving picture composed of a succession of images and of monophonic sounds, comprising the steps of: determining spatial location of at least one zone in motion within said moving picture to be reproduced by analyzing successive images; identifying said zone in motion as corresponding to a source (P) from which sound is originated; and reproducing said succession of images on a display () and corresponding sounds on at least one left loud speaker () and one right loud speaker (), while applying to said sounds at least an audio 3D effect as a function of said spatial location.

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

To amplify low frequencies emitted in handsfree mode by a multifunction earpiece (earpiece, loudspeaker, buzzer) of a telephone handset, the earpiece being tolerant to leaks in a discreet mode of operation, a tube projects into a cavity in the casing of the handset, around an aperture through which the cavity communicates with the exterior of the casing. The handset thus includes a multifunction earpiece that is tolerant of leaks in a discreet mode of operation and provides good sound quality in handsfree mode.

A structural arrangement for a wireless communication terminal includes a case in which are disposed a sound transducer and a patch planar antenna connected to a printed circuit. The transducer has an electrically neutral portion comprising a vibrating membrane and an electrically conductive portion. The antenna incorporates a cavity delimited by a ground plane and a conductive patch disposed on a dielectric support. The electrically neutral portion of the sound transducer is situated in the cavity of the antenna. The electrically conductive portion of the sound transducer constitutes a portion of the ground plane of the antenna.
