A flat plate audio transducer. A front panel and a back panel are connected via a frame. One or more electromagnetic actuators are mounted between the two panels. Voice coils are used as the actuators in some embodiments. Stiffening braces are preferably run between groups of actuators to prevent unwanted resonance phenomena. In some embodiments an actuator array moves both the front and back panels. In other embodiments only one panel is moved.

A sound output apparatus according to the present technology includes a functional mechanism that performs a specified function; an oscillation providing mechanism that oscillates, as an oscillation-provision-target member, a member that is included in the functional mechanism; and an oscillation controller that controls an oscillation operation performed by the oscillation providing mechanism, on the basis of sound information. The oscillation providing mechanism includes an actuator, a support member, and a biasing member. The actuator generates oscillation along a specified oscillation axis, and includes a rear end that is situated opposite to the oscillation-provision-target member in an axial direction of the oscillation axis. The instruction member supports the actuator. The biasing member is provided around the support member as viewed along the oscillation axis and of which at least a portion is arranged closer to the oscillation-provision-target member than the rear end of the actuator in the axial direction of the oscillation axis, the biasing member biasing the support member toward the oscillation-provision-target member. Further, the oscillation-provision-target member includes a sound output region being configured to have a relatively small thickness.
