[0042] Various embodiments are described hereinafter with reference to the figures. Like reference numerals refer to like elements throughout. Like elements will, thus, not be described in detail with respect to the description of each figure. It should also be noted that the figures are only intended to facilitate the description of the embodiments. They are not intended as an exhaustive description of the claimed invention or as a limitation on the scope of the claimed invention. In addition, an illustrated embodiment needs not have all the aspects or advantages shown. An aspect or an advantage described in conjunction with a particular embodiment is not necessarily limited to that embodiment and can be practiced in any other embodiments even if not so illustrated, or if not so explicitly described.
[0043] Fig. 1 is a perspective view of a communication headset system 1 comprising a headset body 2 and a first wearing device 3 comprising a headband 32. The headset system is shown in a decoupled state, where the headset body 2 is decoupled from the first wearing device 3. The headset body 2 comprises a microphone arm 12 with at least one microphone 23 at a free end. The headset body 2 also comprises an outer side facing away from the user when worn and an inner side facing the user. The headset body 2 comprises a user interface with a button 21 on the outer side and a circular coupling protrusion 18 with a non-visible audio port on the inner side. A side wall of the headset body comprises a USB-C socket 40. The end opposite the microphone arm 12 comprises a replaceable battery module 22. The headset system 1 is wireless and all active electronics are comprised by the headset body 2. The first wearing device 3 comprises a headband 32 with a first end 33 and a second end 34. An essentially oval-shaped first carrying device 19A with a circular coupling recess 20 is attached to the first end 33 of the headband 32. The coupling recess 20 is adapted to receive the coupling protrusion 18 of the headset body 2 in a coupled state, where the headset body 2 is rotatably attached to the first carrying device 19A so that it can rotate about an X axis, which coincide with the center axes of the coupling recess 20 and coupling protrusion 8. The first carrying device 19A comprises an earpad 41 which is adapted to abut the ear of a user when the headset system 1 is worn. The second end of the headband 32 comprises a so-called T-bar, which is a small, hinged pad which abuts the opposite side of the head in the worn state.
[0044] Fig. 2 is a side view of the communication headset system 1 in coupled state. As it will be explained further in relation to the following figures, the headset body 2 can rotate about the X-axis in relation to the first wearing device 3. The angle shown in Fig. 2 indicates a so-called active area 8, 9 where the microphone 23 is active. If the user moves the headset body 2 outside the active area into a passive area, the microphone 32 will be passive.
[0045] Fig. 3 is a perspective view of a second wearing device 4 comprising a neckband 35. A first ear hook 42 is arranged at a first end 36 of the neckband 35 and a second ear hook 43 is arranged at a second end 37 of the neckband 35. A second carrying device 19B corresponding to the first carrying device 19A shown in figs. 1 and 2 is hingedly attached to the first end 36 of the neckband 35.
[0046] Fig. 4 is a side view of a third wearing device 38 comprising a hard hat 39. A third carrying device 19C corresponding to the carrying devices 19A, 19B of the first and second wearing devices 3, 4 are attached to the side of the hard hat 39. When the user puts on the hard hat 39 the third carrying device 20 abuts the ear of the user. Non-shown adjustment features may be provided for adjusting the position of the third carrying device 19C in relation to the hard hat 39.
[0047] Fig. 5 is a schematic view of a sensor device 5 and a first sensor activation device 6A of the first wearing device 3. The sensor device 5 comprises a first Hall sensor 13 and a second Hall sensor 14. The first Hall sensor 13 is a “north pole sensor” which means that it is adapted to detect the presence of a magnetic north pole N. The second Hall sensor 14 is a “south pole sensor” which means that it is adapted to detect the presence of a magnetic south pole S. The first carrying device 19A is symmetric about a vertical axis Y. For this reason, it works equally for the user regardless of the user arranging the first carrying device 19A on the left or right ear. The first carrying device 19A comprises two sets of magnets 6A arranged symmetric about the vertical center axis. The sensor device 5 and the sets of magnets 6A provide a firs active area 8, a second active area 9 and a passive area 7. In Fig. 5 the headset body 2 is rotated into the second active area 9. This means, that the headset is in “talk mode” where the microphone is open and receives utterances from the user and forward them to the devices connected to the communication headset system 1. Thus, other persons, devices or systems can have a two-way communication with the headset user. If the headset user rotates the headset body 2 into the passive area 7, the microphone will be passive, whereby no sound will be received by the microphone and forwarded. Magnets 10, 11, 44, 45 of the first carrying device 19A are so arranged that at least one of their magnetic north poles N will be detected by the first Hall sensor 13, when the headset body 2 is in the first or second active area 8, 9. The second Hall sensor 14 will not detect presence of magnetic south poles in any position when the headset body 2 is connected to the first carrying device 19A.
[0048] Fig. 6 is a schematic view of the sensor device 5 and the first sensor activation device 6A with the headset body 2 rotated into the passive area 7. Here, the microphone arm 12 will point upward and the first Hall sensor 13 will no longer detect the presence of magnetic north poles whereby the electronics will mute the microphone. There are two identical magnets 13, 14 in the first active area 8 and two identical magnets 44, 45 in the second active area. There could be only one or more than two to magnets to cover the area. The choice of number, shape and size of magnets depends on magnet material, geometry, sensor sensitivity etc.
[0049] Fig. 7 is a schematic view of the sensor device 5 and a second sensor activation device 6B of the second carrying device 19B. The magnets 46, 47, 48, 49 of the second carrying device 19A are so arranged that at least one of their magnetic south poles S will be detected by the second Hall sensor 14, when the headset body 2 is in the first or second active area 8, 9. The first Hall sensor 13 will not detect presence of magnetic north poles in any position when the headset body 2 is connected to the second carrying device 19A. When the headset body 2 is rotated into the passive area 7, whereby the microphone arm 12 will point upwardly, the second Hall sensor 14 will no longer detect the presence of magnetic south poles whereby the electronics will mute the microphone.
[0050] Fig. 8 is a schematic view of a sensor device and a third sensor activation device 6C of the third carrying device 19C. Here the magnets 50, 51, 53, 53 are arranged so that north pole N will be detected by the first Hall sensor 13 and south pole S will be detected by the second Hall sensor 14 in the first and second active areas 8, 9. No magnetic poles will be detected by the first and second Hall sensors 13, 14, when the headset body 2 is rotated into the passive area 7, whereby the microphone will be passive.
[0051] The muting / un-muting functionality works equally with the first, second and third carrying devices 19A, 19B, 19C. However, the different layout of the magnetic poles differs, whereby the total sensor output S from the sensor device 5 includes information about which of the wearing device 3, 4, 38 that is coupled to headset body. Thus, the same sensor device 5 satisfies two purposes.
[0052] Fig. 9 is a diagram showing essential parts of the headset communication device 1. The headset body 2 comprises the sensor device 5, the microphone 23, a speaker 31, a processor 15, a wireless transceiver 29, an antenna 30 and a replaceable and rechargeable battery module 22. The carrying device 19 comprising a sensor activation device 6 is also shown in Fig. 9. The headset body 2 with the microphone arm 12 is rotatably coupled with the carrying device 19 so it can rotate about the axis X, whereby the microphone arm 12 can be rotated between active areas and passive areas.
[0053] Fig. 10 is a schematic diagram showing a data collection system 16 comprising a communication headset system 1. The data collection system 16 comprises at least one communication system 1 and at least one telecommunication device 25, 26 and a server 17, wherein data about selected wearing device 3, 4 is forwarded by the headset body 2 via to the telecommunication device 25, 26 to the server 17, where it is stored. In Fig. 10 two users 28 wearing a headset communication system 1 are shown. However, to collect valuable data about usage of the headset system, data from thousands of users can be collected and analyzed. Thus, data about the use of muting and the selected wearing device can be collected.
[0054] It has been explained here that the presence of the magnetic north pole is detected or not detected by the first Hall sensor and that the presence of the magnetic south pole is detected or not detected by the second hall sensor. However, the detection does not necessarily be detection or no detection. The sensors may detect a more or less weak magnetic field and the question about whether the headset body is within an active or passive area may be a question of detection a signal of a certain strength. This also applies in relation to the determination of selected wearing device. Thus, if both magnetic north pole and south pole are present with a certain strength, the communication system (1) determines that the third wearind device is coupled to the headset body 2.
[0055] The first, second and third wearing devices can each comprise any of the headband, neckband or hard hat.
[0056] In the embodiments shown here, the microphone signal M is un-muted when the headset body 2 is in the active area and muted when it is in the muted area. Muting the microphone signal could take place several places in the system. F. ex. could a switch in the processor 15 simply switch the signal S off. Alternatively, could power to the microphone, if it is active microphone, be cut off.
[0057] Other functionality could be activated and deactivated in the active and passive areas. Thus, the audio signal A send to the speaker could be muted in the passive area.
[0058] As the different wearing devices may provide different acoustic properties to connection between the speaker 31 and the user’s ear, the detection of type of wearing device 19 may be used by the processor 15 or connected device 25, 26 to adapt the audio signal A sent to the speaker 31.
[0059] The sensor device 5 could also be an RFID sensor and the sensor activation device 6 be an RFID tag,
[0060] The sensor device 5 cold also be an optic sensor.
