| 20090245567 | TWISTABLE RING SPEAKER CONTROL - A twisting ring control for a compact speaker is rotatably mounted on a speaker encircling the speaker baffle. When the ring is rotated in one direction, the ring causes the speaker to be switched off, and when the ring is rotated in the opposite direction, the ring causes the speaker to be switched on. A volume control can be integrated into the same mechanism, and arranged such that, after the speaker is switched on, when the ring is rotated in one direction the volume is increased and when the ring is rotated in the opposite direction the volume is decreased. | 10-01-2009 |
