PANEL AUDIO LOUDSPEAKERS INCLUDING MECHANICALLY GROUNDED MAGNETIC CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18280061 titled 'PANEL AUDIO LOUDSPEAKERS INCLUDING MECHANICALLY GROUNDED MAGNETIC CIRCUIT

Simplified Explanation

The abstract describes a patent application for a device that includes a panel and an electromagnetic actuator attached to the rear side of the panel to create a panel audio loudspeaker. The electromagnetic actuator consists of a coil connected to the panel and a magnet suspended with springs, allowing for relative displacement along an axis when an electric current is applied to the coil. The device also includes a chassis housing the panel, with a grounding assembly between the magnet and the rear panel to ground the magnet to the chassis.

  • Panel audio loudspeaker created by an electromagnetic actuator attached to the rear side of the panel.
  • Electromagnetic actuator consists of a coil, magnet, and spring elements for relative displacement along an axis.
  • Chassis housing the panel with a grounding assembly to ground the magnet to the chassis.

Original Abstract Submitted

A device includes: a panel and an electromagnetic actuator mechanically coupled to a rear side of the panel to form a panel audio loudspeaker, the electromagnetic actuator comprising a coil attached to the rear side of the panel and a magnet suspended with respect to the coil via one or more spring elements, the coil defining an axis, wherein during operation of the device an electric current through the coil varies a relative displacement of the magnet with respect to the coil along the axis. The device includes: a chassis supporting the panel, the chassis comprising a housing for the device, the housing comprising a rear panel on an opposite side of the device from the panel; and a grounding assembly positioned along the axis between the magnet and the rear panel of the device, wherein the grounding assembly mechanically grounds the magnet to the chassis.
