20090115790 | DISPLAY CONTROL DEVICE AND MOBILE ELECTRONIC APPARATUS - A display control device and technique for controlling displays on a display unit, in which a plurality of display segments are two-dimensionally arranged (e.g. a dot matrix type display unit), is provided. The technique is effectively applicable to a write data latch circuit of a memory for storing display data in the display control device, such as, for example, a liquid crystal display control device, a mobile electronic apparatus, etc. A display drive control technique for controlling a moving picture display mode of a display device is also provided. The display drive control circuit controls a picture display mode of a display device for displaying still pictures and moving pictures to a liquid crystal display device, such as, for example, a dot matrix type display devices, an organic EL display device, etc. | 05-07-2009 |
20100277503 | DISPLAY DRIVE CONTROL CIRCUIT - No flicker is displayed on the display screen during display of moving pictures and power consumption can be reduced by adding a high quality moving picture display function. Moreover, the number of times of transfer of moving pictures by comprising a still-picture·text·system·I/O bus·interface and a moving picture interface (external display interface), providing a display operation change register (DM) and a RAM access change register (RM) which are changed selectively depending on display content (display mode) displayed on a display device and displaying the display data on the display device via a picture memory even in the moving picture display mode. | 11-04-2010 |
20140009480 | DISPLAY SYSTEM WITH DISPLAY PANEL AND DISPLAY CONTROLLER AND DRIVER HAVING MOVING PICTURE INTERFACE - No flicker is displayed on the display screen during display of moving pictures and power consumption can be reduced by adding a high quality moving picture display function. Moreover, the number of times of transfer of moving pictures by comprising a still-picture • text • system • I/O bus • interface and a moving picture interface (external display interface), providing a display operation change register (DM) and a RAM access change register (RM) which are changed selectively depending on display content (display mode) displayed on a display device and displaying the display data on the display device via a picture memory even in the moving picture display mode. | 01-09-2014 |

20110135139 | SPEAKER DEVICE - A speaker device includes a voice coil unit and a diaphragm linked to the voice coil unit. A first supporting unit and a second supporting unit elastically support the end portions of the voice coil unit so that the voice coil portion of the voice coil unit can vibrate within the magnetic gap in the direction of the face thereof. Each of the first supporting unit and the second supporting unit has a configuration that is in a shape bent so as to extend up and bend down from an end that is fixed to a fixing position. Thus, a speaker device in which the voice coil unit can vibrate with a greater amplitude is provided. | 06-09-2011 |
20110135140 | SPEAKER APPARATUS - A light weight and low profile speaker apparatus is provided. In one embodiment, the speaker apparatus includes: a frame member; a magnetic circuit; a supporting member disposed on a bottom portion of the frame member for securing and supporting the magnetic circuit at an opposite circumferential end portion of a circumferential wall portion of a first yoke relative to a plate portion; a voice coil unit disposed inside a magnetic gap in the magnetic circuit; a coupling member disposed outward of the circumferential wall portion of the first yoke; and a diaphragm having an inner circumferential end portion coupled to the coupling member. The voice coil unit and the coupling member are joined by a joint member that extends in a direction transverse to the circumferential wall portion of the first yoke; and a space where the joint member joining the voice coil unit and the coupling member can move is formed in each of the circumferential wall portion of the first yoke and the supporting member. | 06-09-2011 |
20110135141 | SPEAKER DEVICE - A speaker device has a magnet, outer yokes, and inner yokes which are assembled so that a magnetic gap is formed between the outer yoke and inner yokes over which a magnetic flux which is generated from the magnet cuts across. A voice coil unit which is linked to a diaphragm is disposed within the magnetic gap, and positioning members determine the positions of the inner yokes and the outer yokes which attach magnetically to the magnet such that a magnetic gap is formed. The speaker device has a magnetic circuit of which the construction facilitates assembly, and recycling of various individual parts is relatively easy. | 06-09-2011 |
20120148086 | COMPOSITE SPEAKER - A composite speaker is disclosed that can more easily be made thin and small, and is configured so that the assembly process of the speaker is easy. A first space that opens to the rear is formed in a main yoke that forms a magnetic field emitter, and a magnetic gap is formed in the first space. A first voice coil, connected to an inner peripheral end of a first diaphragm whose surface area is large, is inserted into the first magnetic gap toward the front direction. A second space that passes through from front to back is provided in the main yoke, a second magnetic field emitter is mounted therein, and a second diaphragm whose surface area is small is provided in front thereof. Because of the structure in which the second magnetic field emitter is housed within the first magnetic field emitter, the front-to-back dimension of the speaker can be reduced. | 06-14-2012 |
