Proximity detection

The invention relates to a method and system for detection of an object in proximity to an electronic device, which method comprises the steps of: -producing, via the processing unit using one or more parameters relating to a loudspeaker, a controlled audio signal; -amplifying using an amplifier at least said controlled audio signal, thereby producing an amplified audio signal at an amplifier output; wherein an amplitude of the controlled audio signal is such that the amplified audio signal is less than or equal to an amplitude determined to be safe for the loudspeaker in view of the one or more parameters, -analyzing at least one of said one or more parameters relating to the loudspeaker to detect a change in response of the loudspeaker; the change in response being caused by an object that is present in the acoustical path of the loudspeaker, -determining, based upon the analysis whether the object is located in close proximity to the electronic device.
