    • An audio processor acquires processed sound data, which is obtained by processing original sound data according to a content of processing defined such that first sound is emitted under the standard sound emission condition, in association with a sound emission device, acquires a control signal, and acquires a device sound emission condition. In order to make second sound emitted by the sound emission device under the acquired device sound emission condition close to the first sound, the audio processor identifies the correction content of the processed sound data based on a difference between the device sound emission condition and the standard sound emission condition, the control signal, and the processed sound data acquired in association with the sound emission device. The audio processor corrects the processed sound data according to the correction content, and supplies the corrected processed sound data to the sound emission device.

    • In a sound field control apparatus, a storage unit stores position information of a plurality of speakers disposed in a three-dimensional space and position information of a sound receiving point. An input unit inputs an audio signal and position information of a virtual audio source. A localization controller localizes the audio signal at a position of the virtual audio source. The localization controller defines a virtual polyhedral solid that has vertices at respective positions of the plurality of the speakers, selects a face of the virtual polyhedral solid through which a directional line from the sound receiving point to the virtual audio source passes, selects speakers located at vertices of the selected face as speakers to which the audio signal is output, and determines ratios of levels of the audio signals to be provided to the speakers located at the vertices of the selected face based on ratios of respective angles between the directional line and straight lines directed from the sound receiving point to the vertices of the selected face.
    • 在声场控制装置中,存储单元存储设置在三维空间中的多个扬声器的位置信息和声音接收点的位置信息。 输入单元输入虚拟音频源的音频信号和位置信息。 本地化控制器将音频信号定位在虚拟音频源的位置。 定位控制器定义虚拟多面体固体,其在多个扬声器的相应位置处具有顶点,选择虚拟多面体固体的面部,通过该面部从声音接收点到虚拟音频源的方向线通过该面,选择位于 所选择的面部的顶点作为输出音频信号的扬声器,并且基于方向线和直线之间的各个角度的比率确定要提供给位于所选择面部的顶点的扬声器的音频信号的电平的比率 从声音接收点指向所选面的顶点的线。

    • An illuminating device achieves higher brightness by improving the utilization efficiency of light from a light source in an illuminating device for emitting plane-shaped light. The backlight device includes a light guide member, and LED units facing side surfaces of the light guide member, and propagates light that is emitted by the LEDs and made incident to the side surfaces in the light guide member so as to emit plane-shaped light from a first main surface of the light guide member. The backlight device includes an insulating reflective member placed outside a second main surface of the light guide member facing the first main surface, and a metal reflective sheet laminated on the insulating reflective sheet on the side opposite to the light guide member.
    • 通过提高发光面照明装置中的光源的光的利用效率,照明装置实现更高的亮度。 背光装置包括导光构件和面向导光构件的侧表面的LED单元,并且传播由LED发射并入射到导光构件的侧表面的光,以便发射平面形状的光 从导光构件的第一主表面。 背光源装置包括位于导光构件的面向第一主表面的第二主表面外侧的绝缘反射构件,以及层叠在与导光构件相反的一侧的绝缘反射片上的金属反射片。
