<p>PURPOSE:To ensure the continuous revolution of a speaker with no winding nor tangling of a signal line round a rotary shaft by attaching the rotary shaft to the speaker and then attaching a rotary transformer to the rotary shaft. CONSTITUTION:A rotary transformer 1 of vertical revolution is attached to a vertical shaft, and a rotary transformer 4 of horizontal revolution is attached to a horizontal shaft respectively. Thus a speaker can continuously revolve vertically and horizontally as shown in its front view. In this view, an inner frame 3 can vertically revolve round a vertical rotary shaft 7 on the basis of an outer frame 2. Then a speaker 5 can horizontally revolve round a horizontal shaft 8 on the basis of the frame 3.</p> |
