An actuator for controlling the operation of an apparatus comprises a panel () and an acoustic sensor (). The panel provides a partition within a building structure, while the acoustic sensor is adapted to detect acoustic waves propagating through the panel. When a user exerts pressure against the panel, the sensor detects the acoustic waves that are formed and emits signals for controlling the operation of an apparatus, such as a doorbell, a light source, a television, a sound system, a ventilation system, a window blind, a radio or an alarm.
