Abstract
The present invention relates to a desktop speakerphone constructed to make the desktop speakerphone less space-consuming while having improved audio qualities. The desktop speakerphone preferably has two microphone clustersmounted at the upper side of the housingcloser towards respective longitudinal endsof the latter, so that each microphone clustercan receive voice sound Afrom one or more of the users. Each microphone clusterpreferably comprises three pressure microphones. Furthermore, within each microphone cluster, the second and third sound inletsare preferably arranged symmetrically on opposite sides of the respective median plane. Within each microphone cluster, the relative arrangement of the three sound inletsdefines a respective microphone axisfor each of the microphone pairs. The microphone axisof the first microphone pairextends through the first and the second sound inlet, while the microphone axisof the second microphone pairextends through the first and the third sound inlet. The microphones are connected to multiple array processors, each configured to provide an array signal in dependence on two or more of the multiple microphone signals. First and second array processor configured to provide array signals in dependence on microphone signals.
