DETAILED DESCRIPTION OF THE FIGURES
[0042] FIG. 1 illustrates a system 10 according to one embodiment of the present disclosure. The system comprises an ear cushion 20 for a headset, a fluid supply 30 and a fluid guide device 40. The fluid guide device 40 is connected by a first interface 22 with the ear cushion 20 and a second interface 32 with the fluid supply 30, so that the ear cushion is in fluid communication with the fluid supply 30. The ear cushion 20 comprises a first opening 70 and a second opening 72. The first opening 70 has a smaller cross section than the second opening 72. The first opening 70 is positioned closer to the first interface 22. The function of the fluid guide device 40 is to guide a fluid from the fluid supply 30 to the ear cushion 20 and/or vice versa.
[0043] FIG. 2 illustrates a cross-sectional view of the ear cushion 20 of one embodiment of the present disclosure as shown in FIG. 1. Inside the ear cushion 20 is a ventilation passage 50 and an air deflector 60. The air deflector 60 is connected with the outer structure/contour of the ear cushion 20 and allows for modification of the fluid flow in the ventilation passage 50. In this embodiment the air deflector 60 extends into the ventilation passage 50 of the ear cushion 20. The first opening 70 is inside the external structure/contour of the ear cushion 20 and provides for a fluid intake or outlet through the opening 70 of the ventilation passage 50 inside the ear cushion 20. The function of a fixing element 90 is to mount the ear cushion 20 to the head, for example by form-locked fixing to the headset. A potential material for the fixing element 90 is plastic. A potential method to connect the fixing element 90 to the basic material of the ear cushion 20 is gluing.
[0044] FIG. 3 illustrates a cross-sectional view of the ear cushion 20′ similar to the embodiment of FIG. 1 of the present disclosure. FIG. 3 shows the same cross-sectional view as FIG. 2. The difference is that the basic material of the ear cushion 20′ is a porous material. Inside the ear cushion 20′ is a ventilation passage 50′ and an air deflector 60′. The air deflector 60′ is connected with the outer structure/contour of the ear cushion 20′ for modification of the fluid flow in the ventilation passage 50′. In this embodiment the air deflector 60′ extends into the ventilation passage 50′ of the ear cushion 20′. The first opening 70′ is inside the external structure/contour of the ear cushion 20′ and provides for a fluid intake or outlet through the opening 70′ of the ventilation passage 50′ inside the ear cushion 20′. The function of a fixing element 90′ is to mount the ear cushion 20′ to the head, for example by form-locked fixing to the head set. A potential material for the fixing element 90′ is plastic. A potential method to connect the fixing element 90′ to the basic material of the ear cushion 20′ is gluing.
[0045] FIG. 4 illustrates a part of the system 10 (see FIG. 1) according to one embodiment of the present disclosure. The fluid supply 30 comprises ventilation slots 34 to allow a flow of a fluid out of the fluid supply 30 into the environment or into the counter direction. A control unit 38 is also optionally integrated into the fluid supply 30. Some parts inside the fluid supply 30 are not shown, for example a pressure changing device and/or a tempering device. The fluid supply 30 has the function to affect a fluid by overpressure or negative pressure, so that the ear cushion is in fluid communication with the fluid supply 30.
[0046] FIG. 5 illustrates a headset 100 according to one embodiment of the present disclosure. The headset 100 comprises ear cushions 20 and cups 24. On the left side of FIG. 5 the ear cushion 20 is connected to the cup 24 and the cup 24 is fixed to a headband 120. On the right side the ear cushion 20 and the cup 24 are shown in a not mounted position. The fluid guide device 40 is connected to the ear cushion 20 by the interface 22 (not shown in FIG. 5) and fixed by clips 110 to the headband 120 of the headset 100. The fixing of the fluid guide device 40 by clips 110 helps that the fluid guide device 40 is not in the way when using the headset 100. Only one fluid guide device is in so that the drawing remains clearly arranged.
[0047] FIG. 6 illustrates a headgear 200 according to one embodiment of the present disclosure. The system 10 of the present disclosure is integrated into the headgear 200.
