How is the transient performance of tactile transducers?
• Bad. Tactile Transducers ring like all high Q systems. Serious EQ’ing helps the response in the frequency domain but time domain problems remain. With tactile transducers, this problem is in a completely different realm than even the worst subwoofer. Remember a tactile transducer is basically a mass on a spring with not much damping. Shaking a couch is, literally, a lot of work. Even if tactile transducers were critically damped, the problem would still remain because you can’t critically damp a 250 pound couch. Think of a tactile transducer pumping energy into a heavy couch, it will take many cycles, maybe a third of a second, for the transducer/couch system to achieve equilibrium / max SPL. Then the input force is turned off, the high Q tactile transducer will continue to oscillate for several cycles, but this is a minor problem, the big problem is trying to get the couch to stop vibrating. And the lower in frequency you go the worse this problem gets. • Consider this series of eve
