Linear (LARs) vibration motors could be classified under the same shape as coin vibration motors, since most of them look just like coin vibration motors on the outside.
Instead of a rotating offset mass (where electric current moves in one direction, and the rotor spins in one direction), Linear vibration motors incorporate a linearly oscillating mass undergoing simple harmonic motion.
Note that while many linear vibrating motors take on the coin form factor and refers to the mechanism of vibration, so in some cases, the shape can be altered, depending on the housing. A great example is Apple’s Taptic Engine, which is Apple’s own custom Linear vibration motor.
Apple’s Taptic Engine, used in the Apple Watch, is a custom linear vibration motor. While it is not the traditional coin form factor, it remains flat and compact.
Advantages/Disadvantages of mini vibrating motors of linear vibrating motor:
Linear motors offer the same advantage as Coin vibration motors, due to compact form factor and the ability to also install via an adhesive backing. While they are generally more expensive, LRAs are very efficient and allow for more precise and complex vibrations for an improved experience.
LRAs are a little more difficult to incorporate and the frequency range at which this motor resonates is a lot narrower, so it requires a more precise signal to achieve optimal vibration.
Examples of LRAs
A common example of where LRAs are used are with newer smartphones and a lot of Apple products with Apple’s Taptic Engine. From the recent generation iPhones to the Apple Watch to the latest Macbook trackpads, LRAs help simulate a more subtle haptic feedback.
Many of Apple’s latest products incorporate LRAs for haptic feedback.
