Patent number: 7408444Abstract: 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).Type: GrantFiled: July 19, 2004Date of Patent: August 5, 2008Assignee: T & A Mobile Phones LimitedInventors: Stéphane Dufosse, Jean-Christophe Villain, Eric Menu, Yves Le Baudour

Patent number: 7142827Abstract: 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.Type: GrantFiled: September 4, 2003Date of Patent: November 28, 2006Assignee: TCL Communication Technology Holdings LimitedInventors: Stephane Dufosse, Jean-Christophe Villain, Eric Menu, Yves Lebaudour

Patent number: 7139394Abstract: 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.Type: GrantFiled: March 19, 2002Date of Patent: November 21, 2006Assignee: TCL Communication Technology Holdings LimitedInventors: Stéphane Dufosse, Nicolas Janaszek
