<p>The vibrator (1) is connected at one point to a bridge (2). This (2) has a clear surface (3) accepting oscillations from a musical instrument (or other source). The vibrator is a wooden couch or tubular body. A rigid spacer (5) below the oscillator, is connected to the bridge. A mounting grid under the couch, connects it to the spacer. The wooden bridge is supported at an oscillatory node. The source, a loudspeaker, contacts the bridge via a pin (9). Slots in the bridge are connected by wing nuts or screws to the spacer.</p> |
