  • Patent number: 11716583
    Abstract: The invention concerns a mobile terminal with at least two transducers (LSm, LSs1, LSS2) used simultaneously as loudspeakers for stereophonic effect. According to the invention, one of said transducers is a main transducer (LSm) with a main working frequency band (Bm) corresponding to at least the phone frequency band, while the other transducer is a secondary transducer (LSs1; LSs2) with a secondary working frequency band (Bs1; Bs2) band different from said main frequency band, the lowest frequencies of said secondary working frequency band (Bs1; Bs2) being greater than the lowest frequencies of said main working frequency band.

  • Patent number: 8064754
    Abstract: 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 (P3) from which sound is originated; and reproducing said succession of images on a display (20) and corresponding sounds on at least one left loud speaker (21) and one right loud speaker (22), while applying to said sounds at least an audio 3D effect as a function of said spatial location.

  • Patent number: 7408444
    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).

  • Patent number: 7142827
    Abstract: In a structural arrangement for radio communication terminals comprising a casing in which are disposed at least a first sound transducer having an earpiece function and a second sound transducer having a loudspeaker function, the two transducers being respectively connected to two opposite faces of a printed circuit card, and each transducer comprising at least one resonating membrane vibrating in a front acoustical cavity and a rear acoustical cavity. The rear acoustical cavities of the transducers communicate with each other via orifices formed in the printed circuit card to form a twin rear acoustical cavity.

  • Patent number: 7139394
    Abstract: 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.
