Abstract
A speaker 300 is formed using a plate such as a mobile phone display window 310 as a vibrating element. At least two dynamic actuators 950 are positioned behind the edges of the window 310 to actuate the window 310 through its boundary region so as to leave a large uniform area behind the vibrating element for containing any components, e.g. a display or battery.
