摘要： A digital acoustic device including: at least one suspended diaphragm facing a support and at least one actuator associated with the diaphragm, the associated actuator being configured to move the diaphragm away from and/or closer to the support; a stop mechanism configured to interrupt movement of the diaphragm further to activating the actuator when the diaphragm has a non-zero speed, the stop mechanism being sized to interrupt the movement of the diaphragm when the movement of the diaphragm is greater than or equal to 50% of the theoretical maximum stroke of the diaphragm and lower than or equal to 95% of the theoretical maximum stroke of the diaphragm.
