    • A material for improving the sound pressure level at the bass reproduction limit of the present invention is composed of an activated carbon having a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 50 angstroms or less. Preferably, this activated carbon has a cumulative pore volume of 0.1 ml/g or less for the pores each having a radius of 7 angstroms or less. In particular, when a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.5 ml/g or more for the pores each having a radius of 18 angstroms or less is installed in a cabinet of a loudspeaker device, the material alleviates pressure fluctuations of a gas within the cabinet caused by vibration of a loudspeaker, and thus a very good bass reproduction effect is attained. Moreover, in the case where a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 18 to 50 angstroms is installed in the cabinet, a loudspeaker device having a good bass reproduction effect even in an atmosphere of high humidity is obtained.
    • 用于改善本发明的低音繁殖极限处的声压级的材料由具有50埃半径的孔的累积孔体积为0.4ml / g以上的活性炭构成。 优选地,对于每个半径为7埃或更小的孔,该活性炭的累积孔体积为0.1ml / g以下。 特别是,在扬声器装置的机壳中安装有对于半径为18埃以下的孔的活性炭的累积孔体积为0.5ml / g以上的声压级改善材料时, 材料减轻由扬声器的振动引起的机柜内的气体的压力波动,从而获得非常好的低音再现效果。 此外,在机壳中安装有对于半径为18〜50埃的孔的活性炭的累积孔体积为0.4ml / g以上的声压级改善材料的情况下,扬声器装置 即使在高湿度的气氛中也能获得良好的低音再现效果。
