Hydro-acoustic massage system and method |
摘要 |
A massage apparatus includes a flexible bladder filled with a fluid and a plurality of bladder displacement devices coupled to the flexible bladder for displacing the flexible bladder in accordance with a specified displacement plan. A signal source is coupled to the bladder displacement devices to provide the specified displacement plan. The signal source outputs first and second frequency modulated (FM) signals. The FM signals are identical in spectrum and start at zero phase, but are propagated 180 DEG out-of-phase with respect to one another. The first FM signal is fed to one half of the bladder displacement devices and the second FM signal is fed to the other half of bladder displacement devices. The FM signals are controlled in such a way that vibrational energy travels in the fluid-filled bladder for coupling to a user reclined on the bladder while ambient vibration of the apparatus is canceled. |
