    • A sound field control unit includes a microphone collecting sound about a self-unit, a collected sound signal input-output terminal for outputting a collected sound signal of the self-unit to outside of the self-unit and inputting a collected sound signal of other units to the self-unit, a collected sound signal switch for switching the collected sound signal collected by the self-unit and that collected by the other units sequentially and repeatedly, an FIR filter for producing a reflected sound component of the collected sound signals provided by the switch and imparting it to the collected sound signals, an amplifier for amplifying the imparted reflected sound component and the collected sound signal, an equalizer provided in a signal path between an output terminal of the collected sound signal switch and an input terminal of the amplifier for adjusting frequency characteristic of a signal flowing through the signal path, and a loudspeaker for reproducing the amplified output signal. These components are assembled integrally together in the self-unit and the self-unit is adapted to be connected to the other units through the collected sound signal input-output terminal by means of transmission cables.

    • A secondary battery of the present invention comprises an electrode assembly in which a strip-shaped positive electrode plate and a strip-shaped negative electrode plate are spirally wound with a strip-shaped separator interposed therebetween, the positive electrode plate comprising a positive electrode current collector and a positive electrode material mixture layer carried thereon, and the negative electrode plate comprising a negative electrode current collector and a negative electrode material mixture layer carried thereon. The positive electrode plate has, in a vicinity of a first end at an initial winding side, an exposed portion of the positive electrode current collector having the positive electrode material mixture layer not formed thereon and a positive electrode lead connected to the exposed portion. A first winding turn outwardly adjacent to a connecting portion of the positive electrode lead with the separator interposed therebetween and a second winding turn outwardly adjacent to the first winding turn with the separator interposed therebetween comprise a portion of the negative electrode plate carrying the negative electrode material mixture layer.
