    • The speaker apparatus according to the invention is arranged in a manner that when the magnitude of an audio signal Sin increases temporarily and so a consumption power increases, a DC-DC converter reduces an output voltage Vout to thereby increase an output current Iout and further discharges a capacitor to thereby increase a current supplied to an amplifier. Thus, a power of 2.5 W or more supplied from a USB connection terminal can be temporarily supplied to the amplifier. Further, since the change of the voltage difference between the both ends of the capacitor can be made large, an amount of the electric charges discharged from the capacitor can be made large and so the size of the capacitor can be reduced.
    • 根据本发明的扬声器装置的布置方式是当音频信号Sin的大小临时增加并且消耗功率增加时,DC-DC转换器降低输出电压Vout,从而增加输出电流Iout并进一步放电 电容器,从而增加提供给放大器的电流。 因此,可以暂时向放大器供给从USB连接端子供给的2.5W以上的功率。 此外,由于可以使电容器的两端之间的电压差的变化大,所以可以使从电容器放出的电荷量变大,因此可以减小电容器的尺寸。

    • An optical connector fitted upon a tip end portion of an optical fiber ribbon and disposed to face an optical input and output terminators which are installed upon a substrate, and which optically connects between optical fibers of the optical fiber ribbon and each of the optical input and output terminators. The optical connector includes a block shaped connector main body which is disposed to face the optical input and output terminators. The connector main body includes a hollow optical fiber holding portion for holding mainly a coating portion of an optical fiber which is led generally in parallel with the surface of the substrate, a plurality of optical fiber apertures into which the tip end vicinity of the optical fibers are inserted and fixed and a concave spot for changing the optical axis comprising a reflective surface for changing the optical axis and formed in front of an exit of the optical fiber apertures, which causes the optical axis direction of the optical fiber to face the optical input and output terminators.
