1. Electrical equipment comprising:
a housing having a hole formed therein;
a microphone positioned inside the housing and in the proximity of the hole;
a loudspeaker;
emitter means arranged to emit an emitted detection sound signal via the loudspeaker;
processor means arranged to acquire a received detection sound signal via the microphone, to detect in real time from the received detection sound signal whether a user's finger is or is not positioned on or in the immediate proximity of the hole, and if a finger is positioned on or in the immediate proximity of the hole to cause a predetermined action to be performed,
wherein the processor means are arranged to implement a bandpass filter around a frequency of the emitted detection sound signal.
