The term chassis originates from the time of the tube devices, which were still built in free wiring without circuit boards. The components such as tubes, transformers, etc. were attached in the device to a construction of steel or aluminum sheet, which was usually placed on ground level.

Often this metal construction is not directly accessible from the outside, and there are devices where the chassis is potentially on a dangerous voltage with respect to ground, so that one must avoid any contact when the device is open.

In newer devices built on the basis of printed circuit boards, a chassis often no longer exists in this form, and the role is taken over by the metallic housing. In this case, the housing is often referred to as the chassis.

In Loudspeakers, the term chassis refers to a construction of basket, diaphragm, voice coil, and permanent magnet. Real loudspeakers contain one or more such chassis, plus possibly other components such as Crossovers.
