摘要： A moving image processor includes a first and a second moving image processing unit which are able to perform parallel operation, and a data transfer unit having a first buffer and a second buffer. The first moving image processing unit processes macroblocks MB00, - - - , of one row of one image sequentially, and the second moving image processing unit processes macroblocks MB10, - - - , of the next row sequentially. The first and the second moving image processors include a first and a second deblocking filters, respectively. Operation timing of the second filter is delayed by the processing time of two macroblocks, compared with operation timing of the first filter. The processing results of the first filter and the second filter are transferred to an external memory via the first buffer and the second buffer of the transfer unit.

摘要： A speaker system provides good acoustic characteristics for use in visual equipment, by controlling the turbulence in mid-range of response frequency characteristics to be flat so as to produce an excellent speech articulation. This is accomplished by coupling an acoustic pipe to the front of a speaker unit to guide sound waves through an opening of generally rectangle shape. A resonance absorption section is formed by a tube, one end of which forms a hole for absorbing sound facing to a sound path running within the acoustic pipe from the front of speaker unit to an opening, and a cavity having a small gap along the edge, except the area where is coupled through with the other end of tube. By constructing the speaker system in this way, the width of band to be absorbed and the Q of a dip can be controlled to suppress the peaks and dips, thereby providing a speaker system of good acoustic characteristics where the response frequency characteristics are flat and the speech articulation is excellent.

摘要： A speaker of the present invention includes a frame at which a magnetic circuit is mounted, a voice coil, an arched diaphragm, and an edge made of material different from that of the diaphragm. A part of the voice coil is disposed at a magnetic gap formed by the magnetic circuit. The diaphragm is coupled with the voice coil, and the edge links the diaphragm with the frame. Further, the diaphragm includes an inner-diameter-fixing part to be joined with the voice coil, an outer-diameter-fixing part to be joined with the edge, and a top part formed between the inner-diameter-fixing part and the outer-diameter-fixing part to protrude forward. A part near the top part differs from a part other than the part near the top part of the diaphragm in at least one of thickness and density. This structure flattened sound-pressure-frequency characteristic over broad bands.
