Vibration feedback device uses an electromagnetic drive system

To improve the operability of electronic products, Alps Electric developed the Force Reactor AF series short-vibration feedback devices, which generate an array of vibration settings. The devices claim to be the first in the industry to generate various short vibration through an electromagnetic drive system.

Many electronic components such as mobile phones and car navigation systems are equipped with an increasing number of touch panels, input sensor devices and other equipment that are operated by the touch of a fingertip. These kinds of devices require visual confirmation of input. However, demand is also rising for vibration, clicking and other sensory functions at the fingertips to indicate to users that their input has been properly accomplished.

The new vibration device from Alps utilizes a proprietary magnetic circuitry to drive an oscillator supported by a spring. According to the company, they achieved this by applying actuator technology cultivated in the development of floppy disc drives. By using magnetism and spring tension for vibration control, balance is created and short-vibration is accomplished, thereby enabling a variety of vibrations. Moreover, with a two-type lineup equipped with vibration strengths of 0.8G and 1.9G respectively, Alps are able to offer a choice of the desired size and vibration power according to each component.
