Abstract (en)
[origin: EP2373065A1] The device has a microphone array including two microphones (2, 2'). An apparatus (10) produces a directivity of the microphone array, and includes two inputs (12, 14). A coupling device (42) couples one of the microphones to one of the inputs, and couples other microphone to other input of the apparatus, respectively. The coupling device simultaneously couples the microphones to both inputs of the apparatus, respectively. The coupling device allows selective interruption of a signal path from the latter microphone to the apparatus for producing the directional characteristic.
