CONSTITUTION:The orchestral accompaniment device 1 is divided into an orchestral device main body 2, a speaker 3, and a monitor 4, which are used while stacked on one over another. Each of the devices has a terminal, formed by joining a copper plate on rubber, at a specific position on its top or bottom surface in a projecting state, and when the devices are stacked on one over another, their corresponding input terminals and input terminals come into contact to make connections. |
