HEARING DEVICE COMPRISING AN ACTIVE VENT AND METHOD FOR ITS OPERATION

The disclosure relates to a hearing device comprising a housing (102, 112, 142, 172, 182, 602, 712) surrounding a venting channel (109, 145, 175, 185 an acoustic valve (151, 181, 191) comprising a valve member (156, 186, 196, 616) moveable relative to the venting channel (109, 145, 175, 185) between different positions comprising a first valve position and a second valve position, an actuator (157) configured to provide an actuation force (161, 162) with a direction and a magnitude acting on the valve member (156, 186, 196, 616), and a controller (106, 126) a controller (106, 126) configured to provide a first control signal controlling the actuator (157) to provide the actuation force (161, 162) in a first direction, and to provide a second control signal controlling the actuator (157) to provide the actuation force (161, 162) in a second direction. The disclosure further relates to a method of operating such a hearing device.To provide an additional functionality of the hearing device, the controller (106, 126) is configured to provide a temporal sequence of signal pulses (406, 416, 446, 456, 466, 476, 486, 496, 516, 526, 536, 546, 556, 559, 565, 566) controlling the actuator (157) to provide the actuation force (161, 162) during a duration (407, 417, 447, 457, 467, 477, 497, 507, 517, 572) of each signal pulse.
