Linear Vibration vs Pivotal Oscillation

Linear vibration: If all the basic components of a vibratory system – the spring the mass and the damper behave linearly, the resulting vibration is known as linear vibration. Principle of superposition is valid in this case. Nonlinear Vibration : If one or more basic components of a vibratory system are not linear then the system is nonlinear.

Linear vibration motor(LRA) provides faster response time and longer usage life when compared with ERMs. As such, linear vibration motor(LRA) is more commonly used in handsets, wearable vibration, mobile phone vibration. Moreover, linear vibration motors(LRA) are capable of vibrating at a more steady frequency with less power drain, delivering better quality for the handset haptics experience. …

Vibration - Wikipedia

In the case of the spring–mass–damper model, the system is linear if the spring force is proportional to the displacement and the damping is proportional to the velocity over the range of motion of interest. Hence, the solution to the problem with a square wave is summing the predicted vibration from each one of the harmonic forces found in the frequency spectrum of the square wave.
