摘要: Apparatus for generating a first acoustic signal and simultaneously sensing a second acoustic signal. The apparatus comprises: an input (15) for receiving a first electrical signal from a signal source; a loudspeaker terminal, directly or indirectly connected to the input (15), for connection to a loudspeaker (30) for generating the first acoustic signal in response to the first electrical signal and for generating a second electrical signal in response to the second acoustic signal; and an output (35), for outputting the second electrical signal. The loudspeaker terminal is connected to the output (35) via isolation means (25) comprising a first filter which is adapted to suppress a signal component related to the first electrical signal while simultaneously passing the second electrical signal to the output (35).

摘要: A loudspeaker drive circuit comprises an input for receiving an audio signal and a signal processor for processing the audio signal before application to the loudspeaker. The signal processor processes the audio signal to derive a loudspeaker drive signal which results in the loudspeaker membrane reaching its maximum displacement in both directions of diaphragm displacement.
