Abstract

An audio device, comprising a casing containing the following components: a. An audiofrequency actuator; b. power supply means; and c. driver means for supplying a driving signal to the actuator; d. a foot extending outside the casing beneath the casing so as to be engageable with a surface into which audiofrequency vibrations generated by the actuator can be coupled, whereby the surface radiates sound, characterised in that the foot is located adjacent to one end of the casing, and a support is located on the underside of the casing adjacent to the end thereof opposite to the said one end, whereby the mass of the device has a moment around said support acting through the foot.
