A fixing body includes a coil holding part that is disposed to surround a magnet externally in a radial direction and holds the coil disposed outside the bobbin-shaped coil holding part in the radial direction. The coil holding part includes a coil protection wall portion that is disposed inside the coil in the radial direction of the coil with a gap being interposed between the coil protection wall portion and the magnet, and inhibits contact between the coil and the movable body. Elastic supporting parts are a plurality of leaf springs installed between the fixing body and the movable body to sandwich the movable body in the vibration direction, and support the movable body such that, in a non-vibration state and in a vibration state of the movable body, the movable body is freely movable in the vibration direction without making contact with the coil holding part.

A vibrotactile actuator includes a network of flat electromagnetic coils positioned contiguously in a plane, the network of coils being able to generate a Laplace force under the effect of an electric current passing through the network of coils, a network of permanent magnets assembled linearly in a plane parallel to the plane of the network of coils and forming a Halbach network generating magnetic field lines oriented towards the network of coils, an electromagnetic interaction between the current lines passing through the network of coils and the magnetic field lines giving rise, as a result of the Laplace force, to relative translational movement between the network of coils and the network of magnets, and an elastic guide device for generating haptic vibrations from the relative translational movements of the network of coils and the network of magnets.

The current document is directed to various types of oscillating resonant modules (“ORMs”), including linear-resonant vibration modules, that can be incorporated in a wide variety of appliances, devices, and systems to provide vibrational forces. The vibrational forces are produced by back-and-forth oscillation of a weight or member along a path, generally a segment of a space curve. A controller controls each of one or more ORMs to produce driving oscillations according to a control curve or control pattern for the ORM that specifies the frequency of the driving oscillations with respect to time. The driving oscillations, in turn, elicit a desired vibration response in the device, appliance, or system in which the one or more ORMs are included. The desired vibration response is achieved by selecting and scaling control patterns in view of known resonance frequencies of the device, appliance, or system.

Provided is a linear actuator including a movable element, a stationary element, a magnetic drive mechanism configured to linearly move the movable element in a first direction with respect to the stationary element, and damper member arranged between the movable element and the stationary element. The magnetic drive mechanism includes a coil holder arranged on the stationary element, a coil supported by a coil supporting unit of the coil holder, a first yoke arranged on the movable element, and a first permanent magnet held by the first yoke. The damper member is arranged in a portion where the first yoke and the coil holder face each other in the second direction. As a result, the damper member can be arranged between the stationary element and the movable element without using a case.
