The invention relates to a method for simultaneously operating a loudspeaker assembly (10) in a loudspeaker function and in a microphone function. The loudspeaker assembly (10) comprises a coil (12), which is movably mounted in the magnetic field of a magnet (14), and a diaphragm (16), which is mechanically coupled to the coil (12), wherein: the magnet (14) produces a magnetic flux density (B); the coil (12) has an effective length (l12) in the magnetic field; the diaphragm (16) has an area (A). In order to determine a first transfer function ZM, a first calibration state is set, in which an external sound pressure (p) on the diaphragm (16) is equal to zero. In order to determine a second transfer function Zc, a second calibration state is set, in which movement of the diaphragm (16) is suppressed. Subsequently, in normal operation the current (I) flowing through the coil (12) and the voltage (U) dropping across the coil (12) are measured and the external sound pressure (p) on the diaphragm (16) is determined using the magnetic flux density (B), the effective length (l12) of the coil (12) in the magnetic field of the magnet (14), the first transfer function (ZM), the second transfer function (ZC), the area (A) of the diaphragm (16), the current (I) measured by the measuring device in normal operation, and the voltage (U) measured by the measuring device in normal operation. The invention further relates to a corresponding loudspeaker assembly (10).
