A sound producing apparatus with multi-directivity has two or more speakers to produce music or other types of audio sounds. Each of the speakers can produce audio sounds in a certain direction and at least one speaker is steerable so that its sound propagation direction relative to the others can be changed. Furthermore, one or more speakers can produce audio sounds in an adjustable angular range. One or more of the speakers can be dual-mode speakers, each of which can be operated as a wide-angle speaker or a narrow-angle speaker. With multi-directivity, it is possible to play one type of music in one direction and another type of music in another direction to suit the interests of the audience. The apparatus can be a mobile phone, an audio player, a digital or analog recorder/player, or the like.

Multi-directivity sound device

An apparatus is provided, which comprises: a display configured to display an image, a sensor arrangement (), and a processing arrangement, wherein the sensor arrangement comprises first, second and third linear sensor arrays (), each of the linear sensor arrays being disposed generally orthogonal to each of the other linear sensor arrays and converging with each of the other linear sensor arrays at or near one end thereof, and wherein the processing arrangement is configured, in response to determining that two consecutive inputs are on different ones of the first and second linear sensor arrays, to rotate the image displayed on the display about a first axis, in response to determining that two consecutive inputs are on different ones of the second and third sensor arrays, to rotate the image displayed on the display about a second axis, the second axis being substantially perpendicular to the first axis, and in response to determining that two consecutive inputs are on different ones of the first and third linear sensor arrays, to rotate the image displayed on the display about a third axis, the third axis being substantially perpendicular to both the first and second axes.

Apparatus including a first liquid crystal layer configured to receive at least a portion of an image and to provide the portion of the image across an angular viewing range; first substantially transparent electrodes positioned adjacent the first liquid crystal layer, the first electrodes being configured to have at least a first configuration in which a first subset of the electrodes provide electric fields across the first liquid crystal layer to form first transparent regions and first opaque regions in the first liquid crystal layer to provide a first angular viewing range, and a second configuration in which a second subset of the electrodes provide electric fields across the first liquid crystal layer to form second different transparent regions and second different opaque regions in the first liquid crystal layer to provide a second angular viewing range, having a different angular viewing range to the first angular viewing range.

An apparatus uses a transducer to produce vibration in the ultrasonic frequency range and in the audible frequency range. A membrane or cantilever structure is coupled to the transducer to produce acoustic waves. When the vibration is in the audible frequency range, the membrane structure works like a conventional loudspeaker. When the vibration is in the ultrasonic frequency range, the ultrasonic signal is modulated by audio signal for creating better directivity. The acoustic waves in the ultrasonic frequency range can reproduce directional audible sound due to the nonlinear interaction of ultrasonic waves in air.

Dual-mode loudspeaker

A portable electronic device including electronic circuitry; and a housing having the electronic circuitry mounted therein. The housing includes a first housing section movably connected to a second housing section by a compliant hinge arrangement. The compliant hinge arrangement includes at least one living hinge. The first and second sections are adapted to longitudinally slide relative to each other.

A multi-layer printed wire board (PWB) structure optimized for improved drop reliability, reliable electrical connections under thermal load, and minimal thickness is provided, along with a mobile terminal, including the PWB. The PWB includes alternating conductive layers and insulative layers. The outermost three layers form an interconnect structure constructed of two conductive layers surrounding an insulative-coated conductive layer. The thicknesses of the various layers are optimized to have an increased resistance to mechanical shock resulting from, for instance, a drop onto a hard surface. In addition, the optimized PWB structure has a minimized thickness and an improved resistance to connection failures resulting from cyclical thermal loads.
