Appl. No.:

09/301658

Inventors:

Matthew J. Murray - Raleigh NC
Scott L. Vance - Cary NC

Assignee:

Ericcson Inc. - Research Triangle Park NC

International Classification:

H04B 138

US Classification:

455 90, 455347, 455550, 455575, 37943313, 379445, 343702, 343882

Abstract:

A portable communication device includes a rotating member and a latching mechanism which employs a magnet means and a quantity of magneto-rheological fluid (âMRâ fluid) or electro-rheological (âERâ) fluid therein to latch the rotatable member against the primary body of the portable communication device when a magnetic or electric field is positioned proximate to the MR or ER fluid. The rotating member can be a low-profile flip and/or antenna. The magnet means can be an electromagnetic field or at least one translatable permanent magnet. Additionally, a portable communication device with a translating antenna and an antenna receptacle and elbow also includes a quantity of magneto-rheological fluid therein. The device can also include an externally accessible latch release which controls the application of the magnetic field to the MR fluid (or electric filed to the ER fluid). Associated latching mechanisms employ rheological fluid and a magnetic or electric field source.

Assignee:

Sony Ericsson Mobile Communications AB

International Classification:

H04B 3/36

US Classification:

3404071, 340679, 340683, 3406863

Abstract:

A tactile generator comprises an eccentric mass that imparts a vibration as it rotates about a rotational axis. The mass is radially movable with respect to the rotational axis such that the distance between the mass and the axis is variable. Varying the distance of the mass from the axis varies the amount of vibration generated when the mass is rotated. The amount of vibration may be controlled responsive to a detected level of ambient noise.

US Classification:

4551142, 455 631, 4551271, 174261

Abstract:

A wireless communications device can include a power amplifier that is configured to transmit information to a wireless communications network during a first time interval and configured to avoid transmitting information during a second time interval. A circuit substrate is coupled to the power amplifier and a power source is configured to provide power to the power amplifier. First and second conductor are coupled to the power amplifier and to the power source, and have respective overlapping and non-overlapping portions on the circuit substrate.

Appl. No.:

10/709010

Inventors:

Matthew J. Murray - Raleigh NC, US

Assignee:

Sony Ericsson Mobile Communications AB - Lund

International Classification:

H04R 25/00

US Classification:

381152, 381431

Abstract:

A transducer assembly includes a transducer and a coupler with rheological material. A loudspeaker further includes an acoustic radiator. The coupler is mounted to the transducer and is operatively connected to the acoustic radiator. The transducer excites bending waves in the acoustic radiator to produce an acoustic output. By control of the rheological material, which may include mageto-rheological liquid or electro-rheological liquid, the transducer in various embodiments may selectively be substantially rigidly or substantially flexibly coupled to the acoustic radiator. If flexibly coupled the force experienced by the transducer when the host device is dropped, jarred, or pressured may be reduced from that experienced with a rigid connection. The acoustic radiator may be, for example, a display such as an LCD or a window mounted over a display. A mobile terminal may include such a loudspeaker in accordance with one embodiment.

International Classification:

H04N 5/222
H04N 5/232

US Classification:

348371, 3482114

Abstract:

A hand-held accessory for a camera-equipped device comprises a short-range transceiver to transmit signals to and receive signals from the camera-equipped device. A controller and a display are operatively connected to the short-range transceiver. The controller generates control signals responsive to user input, and conveys the control signals to the short-range transceiver for transmission to the camera-equipped device. The control signals control the camera functionality on the camera-equipped device. Images captured by the camera-equipped device may be displayed on the accessory display.

Abstract:

A mobile terminal includes a portable terminal housing and a speaker housing positioned in the portable terminal housing. The speaker housing includes a first micro-speaker having a first frequency response and a second micro-speaker having a second frequency response and positioned proximate the first micro-speaker. The terminal housing further includes a first passageway extending from a front face of the first micro-speaker to a first opening in the terminal housing, and a second passageway extending from a back face of the second micro-speaker to a second opening in the terminal housing displaced from the first opening. A grommet adjacent the speaker housing acoustically separates at least a portion of the first passageway from the second passageway. The first passageway may be completely acoustically separated from the second passageway by the grommet and/or a gasket and/or a foam structure. The grommet may define a first outlet extending from a front face of the first micro-speaker to a first location on an external surface of the grommet and a second outlet extending from a back face of the second micro-speaker to a second location on the external surface of the grommet that is displaced from the first location, so that the grommet may acoustically separate the second outlet from the first outlet, although complete acoustic isolation may not be possible.

Abstract:

A printed circuit board for a wireless communications device includes an acoustic path, and acoustically couples microphone circuitry mounted to a surface of the printed circuit board to an exterior of the wireless communications device. A portion of the acoustic path is integrally formed with the printed circuit board and extends generally parallel to the surface of the printed circuit board. One end of the acoustic path is disposed proximate the microphone circuitry and an opposing end opens to receive acoustic sound from the exterior of the wireless communications device. Audible sound propagates through the acoustic path to the microphone circuitry.
