FIG. 1 shows a headset device 100 according to an embodiment.

The headset device 100 comprises at least one ear part 103 comprising an audio module 103a (see also Fig. 3), ahead band 102 attached to the at least one ear part 103 and adapted to fasten the ear part 103 at a user’s head, and a face protection arrangement 101, wherein the face protection arrangement 101 is movably mounted on the at least one ear part 103, wherein the face protection arrangement 101 is movable between at least a first position

(a) (shown in Fig. 1 on the left) and a second position (b) (shown in Fig. 1 in the middle) or (c) (shown in Fig. 1 on the right), wherein in the first position (a) the face protection arrangement 101 is adapted to overlap with the head band 102, and in the second position

(b) or (c) the face protection arrangement 101 is arranged to at least partially cover a user’s face.

The headset device 100 has the advantage that when the user wears the headset device a temporary or continuous protection for the user against microparticles in the air can be achieved, by moving the face protection arrangement 101 into the second position, as shown in Fig. 1 in the middle and in Fig. 1 on the right. Notice that, in the second position

(c), shown in Fig. 1 on the right, the face protection arrangement 101 is compressed against the nose of the user, differently from the second position (b), shown in Fig. 1 in the middle. In particular, a center part lOld (which can also be referred as face cup) of the face protection arrangement 101 can be compressed against the user’s face, when the headset device 100 is in use, and may thus seal the nose and the mouth inside the face cup. A good compression against the facial features of the user can be achieved by having a hollow structure 101c (see also Fig. 6), as it may provide a certain extension capability. In one embodiment, this extension capability may be realized by mechanically sliding a two-piece structure against each other (e.g., a smaller tube fitting into a larger hollow tube).

When the user does not wear the headset device, the headset device can be folded by moving the face protection arrangement 101 into the first position (a). When the user wears the headset device, as shown in Fig. 1 on the left, the first position of the face protection arrangement 101 may also be used, if the mouth and nose of the user do not need to be covered, but the users nevertheless wants to use the headset device 100. In an embodiment, the at least one ear part 103 may be pivotable, and one end 101a of the face protection arrangement 101 is connected to the pivotable ear part 103. Moreover, through a rotational movement of the at least one pivotable ear part 103, the face protection arrangement 101 may be movable from the first position (a) to the second position (b) or (c) and/or vice versa.

In particular, the face protection arrangement 101 may be movably mounted on each of two ear parts 103, 104. Thereby, two ends 101a, 101b of the face protection arrangement 101 may respectively be connected to the two pivotable ear parts 103, 104 (see also Fig. 2).

Moreover, in one embodiment, the headset device 100 can provide preventive protection via networking (e.g. , via Bluetooth connection on the headset device 100 with other headset devices, to enable tracking of infection chains), and/or may provide additional real-time protection by providing air filtering, purification and/or fresh air supply.

As shown in the embodiments of Fig. 1 and Fig. 2, the circular form factors of the ear parts 103, 104 support the ear parts to function as pivoted hinge couplings for the movable face protection arrangement 101. Moreover, the head band 102 can have a U-shape. The face protection arrangement 101 can also essentially have a U-shape, and/or a shape of the head band 102 is essentially the same as a shape of the face protection arrangement 101. This enables an optimal folding of the headset device 100, as shown in Fig. 2 (right side).

In Fig.3 and Fig.4, some additional advantageous elements comprised in the headset device 100 are shown, which are explained in the following

In particular, at least one of the ear parts 103 and 104 may contain an audio module 103a and 103b. Each audio module 103a, 103b may, for example, comprise a speaker, a microphone and/or supportive electronics (e.g. Bluetooth). Different audio modules can be located on opposite side ear parts 103 and 104 connected by the U-shaped head band 102.

Moreover, in one embodiment, the head band 102 may comprise a battery compartment 102a, as shown in Fig. 3, which can be used to accommodate a long-lasting battery due to a possibly large available internal space. Further, the head band 102 may also comprise electronic peripherals, for instance, one or more wireless units.

According to an embodiment, as shown in Fig. 4, the two ear parts 103 and 104 may also contain small, electrically propelled elements, in particular, propelled filtering units (e.g., having motor operated fans 103b, 104b and optionally replaceable filters 103 c, 104c) for feeding air inside a hollow structure 101c of the face protection arrangement 101. To this end, for example, a hinge mechanism, which may arranged between each of the two ear parts 103 and 104 and the face protection arrangement 101, may contain openings. In this way, a channeling connection may be maintained during rotation of the face protection arrangement 101.

FIG. 5 shows that a fan 103b-l and a motor 103b-2 may be comprised in the headset device 100, according to an embodiment.

In this embodiment, the headset device 100 may comprise the motorized fan 103b which, in turn, may comprise the fan 103b- 1 and the motor 103b-2, which may be configured to feed air into the hollow structure 101c of the face protection arrangement 101.

In particular, the motorized fan 103b can be configured to feed air through external filter elements 103c, 104c, in particular, via an ne internal flow channel in the hollow structure of the face protection arrangement 101, to the user’s nose and mouth, particularly on both sides. Sustaining a slight overpressure inside the face protection arrangement 101 compared to the surrounding air may be advantageous as it may diminish air leakage into the face protection arrangement 101 through other paths except the filtered ones.

This provides the advantage that the user can effortlessly breath. Also self-care/treatment can be performed by applying the overpressure (e.g., when the normal operation of the lungs is not adequate). Pulsating operation of the air flow can further simulate a real medical level equipment. Thereby, sensors lOlf may be arranged along the air path, and may measure a breathing rate (see also Fig. 9). Pulsating operation of the air flow can also extend the battery operating time of a battery of the headset device 100.

FIG. 6 shows a headset device 100 according to an embodiment.

In the embodiment shown in Fig. 6, the face protection arrangement 100 may have a U- shape and may comprises a hollow structure 101c formed, e.g., by a plastic frame of the face protection arrangement. The face protection arrangement 101 can be able to be moved by an angle a between 0°... .130° degrees.

At least a part of the face protection arrangement 101 can contain soft, e.g. polymer/silicone based membrane, which may be stretched to cover a widening portion or center part 101 d of the face protection arrangement 101 and optionally the upper and/or lower side of the face protection arrangement 101.

Moreover, the face protection arrangement 101 can contain one or more integrated smart functions, which may target to purify the air flow 600, and/or analyse the air flow 600, and/or adjust flowrate of the air flow inside the face protection arrangement 101. The smart functions may also provide respirational assistance to the user. Each of the smart functions can be configured to utilize peripherals, and/or wireless capabilities and/or rechargeable battery of the headset device 100. The face arrangement protection 101 can also provide an isolated channel for an audio receiver, thereby enabling a high quality communication capability.

In one embodiment, the headset device 100 is configured to combine various mobile technologies such as wireless audio, networking, and/or communication with the mobile handset on the one hand, and on the other hand advanced air filtration solutions, for instance, for atmospherical pollution generated by micro particles.

FIG. 7 shows a headset device 100 according to an embodiment.

In the embodiment shown in Fig. 7, the air flow 600 circulates through the hollow structure 101c of the face protection arrangement 101, in particular between the at least one ear part 103 and the center part 1 Old of the face protection arrangement 101.

The face protection arrangement 101 can comprise the two filters 103c, 104c, which can work in such a way that one is feeding the air inside, and the other one is pushing the air out. Moreover, the face protection arrangement 101 can comprise one or more internal flow sensors and/or sensing elements lOlf (see Fig. 9) for sending and/or controlling the air flow. For example, the sensors and/or sensing elements 10 If can be configured to analyze both environmental air inlet (in-flow) and outlet (out-flow) and human breathing air, inhaled and exhaled. In particular, the sensors and/or sensing elements lOlf can be configured in such a way that, even in the case that the face protection arrangement 101 is not in the second position, but folded up in the first position, it automatically and periodically in-flows a portion of environmental air through it and, then, issues an indication or alarm (e.g., beeps loudly) if a pollution level of the air is above a threshold value. In one embodiment, the sensors and/or sensing elements lOlf can also be configured to detect carbon monoxide, which is an odorless, tasteless and invisible gas, when, for example, charged overnight, to monitor a house safety. It is also possible to detect e.g. coughing effects. For example, in such a case, both filters 103c and 104c can momentarily work in non-suction mode and push the bacterized air outside (for the filters 103c and 104c to catch it) at full speed.

FIG. 8 shows a headset device 100 according to an embodiment.

The audio headset 100 can comprise an electromechanically propelled air flow function, for feeding filtrated air into the user’s nose and mouth, which may otherwise remain isolated from the environment. The audio headset device 100 can also assist the respiration of the user, for example, during asthmatic seizures. To this aim, the headset device 100 can comprise UV-LEDs lOle configured to shine UV radiation onto the air flow through the face protection arrangement 101 , in order to eliminate bacteria or the like. In particular, the face protection arrangement 101 may in particular comprises at least one ultra violet LED lOle configured to clean the air flowing in the hollow structure 101c of the face protection arrangement 101.

As shown in Fig. 8, the air can also be cleaned by using disinfecting illumination along the air flow path 600. In particular, a set of ultraviolet light emitting diodes lOle can be populated to this end along the internal flow path through the face protection arrangement 101 to eliminate bacteria during air migration.

Further, the headset device 100 may comprise one or more sensors lOlf (see Fig. 9) for measuring the air quality (e.g., filtered air vs. surrounding air).

FIG. 9 shows a headset device 100 according to an embodiment.

In this embodiment, the face protection arrangement 101 comprises at least one sensor 101 f configured to measure a quality of air flowing in the hollow structure 101c of the face protection arrangement 101. As shown in Fig. 9, the sensors lOlf can be placed along the air flow path in order to measure the air quality.

The face protection arrangement 101 can be folded up when not used. However, in the folded configuration, it may still be able to analyze the environmental air quality via the integrated sensors lOlf Depending on the location of the sensors 10 If and the air flow 600 inside the face protection arrangement 101, the sensors 101 f may also be usable in analyzing the exhaled air. This can also be used for deducing information about a weight loss prediction (ketones), asthma (nitric oxide), diabetes (acetone), and/or a blood alcohol level of the user.

FIG. 10 shows a headset device 100 according to an embodiment.

In this embodiment, the face protection arrangement 101 comprises at least one heating element 101g configured to heat air flowing in the hollow structure 101c of the face protection arrangement 101.
