    • An acoustic device, which reproduces an acoustic signal of one acoustic source selected from a plurality of acoustic sources. A first averaging unit averages signal levels of the acoustic signal for a first time period to obtain a first average signal. A second averaging unit averages the signal levels for a second time period shorter than the first time period to obtain a second average signal. A selecting unit selects either the first average signal or the second average signal as one signal having a signal level higher than the other. A gain decreasing unit decreases a gain of the acoustic signal according to the signal level of the one signal if the signal level of the one signal is higher than a threshold value determined according to the one acoustic source. A correcting unit corrects the signal levels of the acoustic signal according to the gain.
    • 声学装置,其再现从多个声源中选择的一个声源的声信号。 第一平均单元对第一时间段的声信号的信号电平进行平均以获得第一平均信号。 第二平均单元对比第一时间段短的第二时间段的信号电平进行平均以获得第二平均信号。 选择单元选择第一平均信号或第二平均信号作为信号电平高于另一信号的一个信号。 如果一个信号的信号电平高于根据一个声源确定的阈值,则增益减小单元根据一个信号的信号电平降低声信号的增益。 校正单元根据增益校正声信号的信号电平。

    • An electrical storage device includes a plurality of power-generating elements, a case, and a valve. The power-generating elements perform charge and discharge and are connected electrically in series. A plurality of housing sections each accommodate one of the plurality of power-generating elements and are disposed along a predetermined direction. A communication path switches from a closed state to an opened state depending on the internal pressure of the housing section. When the communication path is in the opened state, gas can be moved between two of the housing sections adjacent to each other in the predetermined direction. The valve is provided for a particular housing section and releases gas produced within the case to the outside of the case. The empty space other than the power-generating element is present in each of the housing sections, and the empty space in the particular housing section is the largest.
    • 蓄电装置包括多个发电元件,壳体和阀。 发电元件进行充放电并串联电连接。 多个壳体部分各自容纳多个发电元件中的一个并且沿预定方向设置。 通信路径根据容纳部的内部压力从闭合状态切换到打开状态。 当通信路径处于打开状态时,气体可以在预定方向上彼此相邻的两个壳体部分之间移动。 阀被设置用于特定的壳体部分,并将壳体内产生的气体释放到壳体的外部。 除了发电元件之外的空的空间存在于每个壳体部分中,并且特定壳体部分中的空的空间是最大的。
