20090251798 | LENS ACTUATOR AND CAMERA MODULE WITH SAME - A lens actuator for driving a lens received in a lens barrel includes a plate shaped body comprising a through hole defined in the center thereof, an inner portion surrounding the through hole, an outer portion for mounting the lens barrel thereon, and a plurality of resilient portions connected between the inner portion and the outer portion. A plurality of piezoelectric structures formed on the respective resilient portions. The piezoelectric structures are configured for mounting the lens thereon and driving the lens to move relative to the lens barrel. | 10-08-2009 |
20090309582 | APPARATUS AND METHOD FOR DETECTING POSITION OF MAGNETIC ELEMENT - An exemplary apparatus for detecting whether a magnetic element is mounted at a correct position on a retaining member is provided. The apparatus includes a holder, a magnetoresistive sensor, and a processor. The magnetoresistive sensor is held by the holder and capable of sensing a present magnetic flux from the magnetic element to the magnetoresistive sensor. The processor is electrically connected to the magnetoresistive sensor and has a predetermined reference magnetic flux stored information therein, configured for obtaining the present magnetic flux and comparing the present magnetic flux with the reference magnetic flux information, thereby detecting whether a magnetic element is mounted at a correct position on a retaining member. | 12-17-2009 |
20090310224 | LIQUID LENS AND LENS MODULE HAVING SAME - The present disclosure relates to a liquid lens and a lens module having the same. The liquid lens includes an enclosure, an elastic shell and a light pervious liquid. The enclosure has a top wall and defines a through opening in the top wall. The elastic shell is received in the enclosure and is filled with the light pervious liquid. The elastic shell includes an inner portion and an outer convex portion. The convex portion protrudes from the outer enclosure via the through opening. | 12-17-2009 |
20090322930 | PORTABLE ELECTRONIC APPARATUS - A portable electronic apparatus includes a main body, a camera device, and a supplementary light device. The camera device and the supplementary light device are fixed on the main body. The supplementary light device includes a light module, a lens module, and a motor. The light module includes a circuit board, a light source, and a heat sink opposite to the light source. The lens module includes a lens barrel and a plurality of lenses received in the lens module. The motor drives the lens module to change the intensity distribution of the light from the light module. | 12-31-2009 |
20130162059 | ACTUATOR HAVING TWO-STAGE ZOOM FUNCTION - An actuator includes a bracket, permanent magnetic elements, a fixing barrel, and a movable unit. The actuator forms a central axis. The bracket includes a front frame and a rear frame connected with the front frame. Both the front frame and the rear frame include a supporting plate. Each supporting plate defines a through hole coaxial with the central axis. The permanent magnetic elements are positioned on supporting plates of the front and rear frames and surround through holes of the front and rear frames. The movable unit includes a hollow core member and a coil group wrapping around the core member. A height of the core member is smaller than that of the fixing barrel. The core member is movably received in the fixing barrel. The fixing barrel is housed in the bracket, and is sandwiched between the permanent magnetic elements. | 06-27-2013 |
20130170040 | LENS MODULE INCLUDING VOICE COIL MOTOR AND IMAGE SENSOR MODULE - A lens module includes an image lens module and a voice coil motor (VCM) supported on the image lens module. The image lens module includes a seat and a spring element. The seat includes a top surface and a bottom surface opposite to the top surface and defines a notch on the top surface. The spring element is received in the notch, and part of the spring element protruding out of the notch. The VCM includes a lower plate supported on the top surface and the part of the spring element protruding out of the notch. Optical axes of the image lens module and the VCM are aligned with each other by pressing the spring element. | 07-04-2013 |
20130170052 | VOICE COIL MOTOR AND LENS MODULE INCLUDING SAME - A voice coil motor includes a case, a moving barrel, magnetic elements, a lower plate, an elastic plate, a first and a second coil assemblies. The case includes an upper plate and a sidewall extending downward from peripheral edges of the upper plate. The upper plate and the sidewall cooperatively define a receiving room. The moving barrel is received in the receiving room. The magnetic elements are received in the receiving room and surround the moving barrel. The lower plate is positioned on one end of the sidewall The elastic plate is connected between the upper plate and the moving barrel or between the lower plate and the moving barrel. The first coil assembly includes pairs of coils. Each pair of the coils is opposite to each other and attached on the moving barrel. The second coil assembly is annular shaped and sleeved over the moving barrel. | 07-04-2013 |
20130170055 | LENS MODULE CAPABLE OF ALIGNING VOICE COIL MOTOR WITH IMAGE SENSOR MODULE - A lens module includes an image lens module and a voice coil motor (VCM) supported on the image lens module. The image lens module includes a seat and an elastic element. The seat includes a top surface and a bottom surface opposite to the top surface and defines a notch on the top surface. The elastic element is received in the notch, and part of the elastic element protrudes out of the notch. The VCM includes a lower plate supported on the top surface and the part of the elastic element protruding out of the notch. | 07-04-2013 |
