Description
A MONAURAL HEADSET WITH AN ABUTMENT ELEMENTFIELD
[0001] The present invention relates monaural headsets configured to be worn by a user on the user’s head. More specifically, the disclosure relates to a monaural headset comprising an ear phone configured to be arranged on a first ear of the user, a headband configured to be arranged on the user’s head, and an abutment element configured to be arranged on the user’s head in the area of the second ear of the user.BACKGROUND
[0002] Some people wear a headset or a hearing device for extended periods of time during a day, e.g. as part of their work day. When wearing a headset or hearing device for a long time, it is very important that the wearing comfort of the headset is high for obtaining a good user experience with the headset.
[0003] Thus, there is a need for a headset with animproved pressure distribution of the headset on the user’s head, because an improved pressure distribution on the user’s head will improve the wearing comfort of the headset for the user.SUMMARY
[0004] Disclosed is a monaural headset configured to be worn by a user on the user’s head. The headset comprises an ear phone configured to be arranged on a first ear of the user. The headset comprises a headband configured to be arranged on the user’s head. The headband is connected to the ear phone in a first end of the headband. The headset comprisesan abutment element configured to be arranged on the user’s head in the area of the second ear of the user. The abutment element is connected to the headband in a second end of the headband. The abutment element is connected to the headband via a pivotable element. The pivotable element is arranged at the abutment element.
[0005] A monaural headset is a headset with one earphone for one ear of the user. This is in contrast to binaural headset which has two earphones, i.e. an earphone for both ears of a user. Thus, a user wearing a monaural headset receives sound from the headset only in the one ear where the earphone is arranged. There are different advantages of a monaural headset, for example if the user wishes to be able to easily hear sound from the surroundings with the other ear, then it is an advantage to use a monaural headset.
[0006] The monaural headset is for wearing on the user’s head.
[0007] The headset comprises an ear phone configured to be arranged on a first ear of the user. Thus the first ear will be the ear where the earphone is arranged, and where the user receives sound from the headset. The other ear, or second ear, is the ear which is not covered by the earphone, and the ear which the user can use for easily hear sound from the surroundings.
[0008] The ear phone may be an on-the-ear ear phone, or an over-the-ear ear phone, or an in-the-ear earphone etc. Thus, the ear phone may at least partly cover the ear, such ascover more or less of the ear of the user, when worn in its intended position. The earphone may completely cover the ear, such as completely cover the surface of the ear, or such as completely surround the ear. The ear phone may partly cover the ear.
[0009] The ear phone may comprise a soft cushion ensuring comfort for the user, and a fabric may be arranged on the outside of the cushion.
[0010] The ear phone may comprise a speaker, or output transducer or loud speaker, or the ear phone may be accommodated for insertion of a detachable speaker. In the latter case, the ear phone may be a carrying device for insertion of a speaker. Thus, the ear phone may comprise electronics or the ear phone may not comprise electronics.
[0011] The headset comprises a headband configured to be arranged on the user’s head. The headband may be for wearing the headset, e.g. for holding the ear phone, and for resten on the user’s head. The headband is connected to the ear phone in a first end of the headband.
[0012] The headset comprises an abutment element configured to be arranged on the user’s head in the area of the second ear of the user, when the headset is worn in its intended position on the user’s head. The abutment element is connected to the headband in a second end of the headband. The abutment element is for providing a comfortable pressure distribution on the user’s head.
[0013] The abutment element may also ensurethat the headset is securely attached to the head of the user. When there is an ear phone in only the first end of the headband, then there may be another part in the other, second end of the headband, for ensuring that the headset stays on the head of the user, and the abutment element provides this function.
[0014] The headset may apply some pressure to the user’s head for staying in position on the head. A clamping force from the headset may be applied to the head of the user for clamping the headset to the head of the user. The abutment element may also be known as a “T-bar” . The abutment element is configured for abutting to the head of the user.
[0015] The abutment element is configured to be arranged on the user’s head in the area of the second ear of the user, thus the abutment element may not be arranged on the second ear of the user. The abutment element may be arranged above the second ear of the user, such as adjacent to the top of the second ear, such as on the head above the second ear. The abutment element may be arranged behind the second ear of the user, such as adjacent to the side of the second ear, such as on the head behind the second ear. Thus, if the user has hair, then the abutment element may be arranged on the hair of the user. If the user does not have hair, then the abutment element may be arranged on the skin of the user’s head.
[0016] The abutment element is connected to the headband via a pivotable element. Thus, the pivotable element may be a connection element between the headband and the abutment element. The pivotable element is configured for pivoting, thus the pivotable element provides that the abutment element is pivotable relative to the headband, and / or vice versa.
[0017] The pivotable element is arranged at the abutment element. Thus, the pivotable element may be arranged at the abutment element, such as in the abutment element, and / or on the side of the abutment element, and / or adjacent to the abutment element.
[0018] The pivotable element may be a ball joint, and the ball joint is then arranged at the abutment element in the present invention. In prior art, a ball joint is arranged in the headband, such as in a headband housing.
[0019] It is an advantage to arrange the pivotable element in the abutment element, because hereby the pivotable element, and thereby the pivot point between the abutment element and the headband, will be closer to the user’s head, because the abutment element is closer to the user’s head than the headband is in that area of the headset.
[0020] It is an advantage that the pivotable element, and thereby the pivot point between the abutment element and the headband, is closer to the user’s head, such as as close as possible, because this will provide a more evenly pressure distribution of the headset on the user’s head. Anevenly pressure distribution onthe user’s head will improve the wearing comfort of the headset for the user.
[0021] In some embodiments, the abutment element comprises an abutment surface adapted to abut to the user’s head, when the headset is worn in its intended position. The pivotable element is arranged at the abutment element at a minimal distance L3 from the abutment surface of the abutment element. Thus, the abutment surface is the face of the abutment element pointing towards the user’s head, when the headset is worn in its intended position on the user’s head. The pivotable element, such as a center of the pivotable element, is arranged at the abutment element at a minimal distance, e.g. as close as possible, to the abutment surface. Thus, the minimal distance L3 may be as small as possible.
[0022] It is an advantage that the pivotable element is arranged at the abutment element at a minimal distance L3 from the abutment surface of the abutment element, because this will provide that the pivotable element, and thereby the pivot point between the abutment element and the headband, is closer to the user’s head, such as as close as possible, and this will provide a more evenly pressure distribution of the headset on the user’s head.
[0023] In some embodiments, the pivotable element is arranged at a minimal distance L3 from the abutment surface of the abutment element for ensuring that the pivotable element between the abutment element and the headband is as close to the user’s head as possible. The center of the pivotable element, such as the center of a ball-joint, may be arranged at a minimal distance L3 from the abutment surface of the abutment element.
[0024] In some embodiments, the minimal distance L3 is between 2.0 mm –2.4. mm, such as between 2.1 mm –2.3 mm, such a 2.2 mm.
[0025] In some embodiments, the pivotable element between the abutment element and the headband is provided as close to the user’s head as possible for ensuring even pressure distribution of the headset on the user’s head. An even pressure distribution may be an optimum pressure distribution, because this will provide more wearing comfort for the user.
[0026] In some embodiments, the pivotable element is arranged at the centre of the abutment element. The centre of the abutment element may be defined as the center of mass of the abutment element, or as a geometrical center, or as a structural center etc. The abutment element may be shaped as a circle, or as an oval, or as a rectangle, or as a square etc.
[0027] It is an advantage that the pivotable element is arranged at the centre of the abutment element, because this may provide a more evenly pressure distribution of the headset on the user’s head.
[0028] In some embodiments, the pivotable element comprises a ball-joint.
[0029] In some embodiments, the abutment element comprises a first part facing towards the headband, wherein the pivotable element is arranged at the first part, and wherein the abutment element comprises a second part at the abutment surface facing towards the user’s head, when the headset is worn in its intended position.
[0030] The abutment element may be substantially flat in the normal direction to the user’s head, when the headset is worn in its intended position on the head. The flat shape may have two sides, whereby the abutment element comprises a first part facing towards the headband, and this first face may be a rigid plastic part. The pivotable element may be arranged at the first part, because this is the face of the abutment element which points towards the headband, where the abutment element is connected to.
[0031] The abutment element comprises a second part at the abutment surface facing towards the user’s head, when the headset is worn in its intended position. The second part is configured to point towards the user’s head and also abut to the user’s head. This second part may therefore be covered in a soft resilient material, such as a foam, for improved comfort for the user.
[0032] In some embodiments, the thickness (Z) of the abutment element is between 2 mm -8 mm, and wherein the length (X) of the abutment element is between 45 mm –65 mm, and wherein the width (Y) of the abutment element is between 15 mm –35 mm.
[0033] Thus, the thickness (Z) of the abutment element is between 2 mm -8 mm, such as between 4 mm –8 mm, such as between 5 mm –7 mm, such as 6 mm.
[0034] The length (X) of the abutment element is between 45 mm –60 mm, such as between 50 mm –60 mm, such as 53 mm –57 mm, such as 55 mm.
[0035] The width (Y) of the abutment element is between 15 mm –35 mm, such as between 20 mm –35 mm, such as 25 mm –35 mm, such as 27 mm –32 mm, such as 30 mm.
[0036] In some embodiments, the abutment element is attached to the headband by an attachment element inserted via the abutment element and attached into the headband, and wherein the attachment element is inserted in a cap in the abutment element, and wherein the cap is arranged in the first part of the abutment element.
[0037] Thus, the abutment element may be attached to the headband. The abutment element may be detachably attached to the headband, such that the abutment element can be replaced by a new abutment element if the previous abutment element is worn out.
[0038] The abutment element may be attached to a base at the headband, where the base is an abutment element base. The abutment element may be attached to the headband by an attachment element, and the attachment element may be a screw.
[0039] The abutment element is attached to the headband by an attachment element inserted via the abutment element, thus may be inserted through the abutment element, such as through a through-hole in the abutment element. The abutment element may be attached into the headband, such as screwed into the headband, e.g. into the base of the headband, with the attachment element, e.g. a screw. The attachment element, e.g. the screw, may be fastened at the base of the headband with a nut.
[0040] Furthermore, the attachment element may be inserted in a cap in the abutment element, and wherein the cap is arranged in the first part of the abutment element. The first part of the abutment element may be a rigid plastic part, and which points towards the headset.
[0041] In some embodiments, the second part of the abutment element covers the attachment element and the cap in the first part of the abutment element. The attachment element and the cap are in the first part, e.g. therigid plastic part, of the abutment element. The second part, e.g. the soft, resilient part, of the abutment element may cover the attachment element and the cap, whereby the attachment element and the cap are not visible.
[0042] In some embodiments, the abutment element is configured to rotate about the attachment element and the cap in the abutment element for providing the pivotable element. Thus, the abutment may rotate or pivot relative to the attachment element, e.g. the screw, and the cap, which are arranged in the abutment element and connected to the headset, and thereby the pivotable element is provided.
[0043] In some embodiments, a gap is provided between an outer surface of the cap and a surface of the first part of the abutment element for ensuring free movement of the abutment element relative to the headband. Thus, due to the gap which may provide an air space, the abutment element can move, rotate and / or pivot relative to the headband, and thereby the abutment element can be arranged in different angles relative to the headset, which allows for an improved fit on the user’s head, and provides for a good fit on different head shapes and head forms.
[0044] In some embodiments, an upside normal force Fn1is approximately equal to a downside normal force Fn2, where the upside normal force Fn1and the downside normal force Fn2are forces of the abutment element on the user’s head, when the headset is worn in its intended position. Thus, the arrangement of the abutment element and the pivotable element in the headset, where the pivotable element is arranged at the abutment element, providing that the pivotable element, and thereby the pivot point between the abutment element and the headband, will be closer to the user’s head, will ensure that the upside normal force Fn1is approximately equal to a downside normal force Fn2, and this will provide an even pressure distribution of the headset on the user’s head.
[0045] The headset may apply three external forces being a force F1 for the abutment element side, and a force F2 for the ear phone side, and gravity G, to the user’s head to keep balance, see also fig. 5a:
[0046] F1 + F2 + G = 0
[0047] For the abutment element side, F1 may be divided to the following three parts: f being a frictional force, and Fn1being the upside normal force, and Fn2, being the downside normal force.
[0048] If assuming that the pivotable element is smooth and slippery, i.e. assuming no resistance, then the moment M for the pivotable element is 0, since:
[0049] M = f *l3+ Fn1*l1+ Fn2*l2= 0
[0050] See also fig. 5c, where l3or L3 is the minimal distance between the pivotable element and the abutment surface of the abutment element, which is measured along the thickness Z of the abutment element.
[0051] And where l1is a distance along the width Y of the abutment element, measured from the pivotable element, which is approximately in the centre of the abutment element, and then up to the end of the abutment element along the width.
[0052] And where l2is a distance along the width Y of the abutment element, measured from the pivotable element, which is approximately in the centre of the abutment element, and then down to the other end of the abutment element along the width.
[0053] If l3or L3 is minimal, i.e. l3→0, i.e. l3or L3 assumed to be close to 0, then:
[0054] Fn1*l1+ Fn2*l2= 0
[0055] And thereby:
[0056] Fn1≈ Fn2
[0057] Thus, when the upside normal force Fn1is approximately equal to the downside normal force Fn2, then the pressure distribution from the headset on the user’s head is uniform and even.
[0058] The present invention relates to different aspects including the headset described above and in the following, and corresponding device parts, each yielding one or more of the benefits and advantages described in connection with the first mentioned aspect, and each having one or more embodiments corresponding to the embodiments described in connection with the first mentioned aspect and / or disclosed in the appended claims.BRIEF DESCRIPTION OF THE DRAWINGS

[0065] 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.
[0066] Fig. 1 schematically illustrates an exemplary prior art monaural headset with a headband and a T-bar (an example of an abutment element) , and where the T-bar is connected to the headband via a ball-joint (an example of a pivotable element) , and where the ball-joint is arranged in the headband.
[0067] Fig. 2a and 2b schematically illustrates an exemplary a monaural headset 2 according to the invention. The monaural headset 2 is configured to be worn by a user on the user’s head. The headset 2 comprises an ear phone 8 configured to be arranged on a first ear of the user. The headset 2 comprises a headband 12 configured to be arranged on the user’s head. The headband 12 is connected to the ear phone 8 in a first end 14 of the headband 12. The headset 2 comprises an abutment element 16 configured to be arranged on the user’s headin the area of the second ear of the user. Theabutment element 16 is connected to the headband 12 in a second end 20 of the headband 12. The abutment element 16 is connected to the headband 12 via a pivotable element 22. The pivotable element 22 is arranged at the abutment element 16.
[0068] As seen in fig. 1 above showing the prior art, in prior art a ball joint, which is an example of a pivotable element, is arranged in the headband.
[0069] It is an advantage of the present invention to arrange the pivotable element in the abutment element instead of in the headband, because hereby the pivotable element, and thereby the pivot point between the abutment element and the headband, will be closer to the user’s head, because the abutment element is closer to the user’s head than the headband is.
[0070] It is an advantage that the pivotable element, and thereby the pivot point between the abutment element and the headband, is closer to the user’s head, such as as close as possible, because this will provide a more evenly pressure distribution of the headset on the user’s head. An evenly pressure distribution of the user’s head will improve the wearing comfort of the headset for the user.
[0071] Fig. 2b further shows the thickness (Z) of the abutment element, and the length (X) of the abutment element, and the width (Y) of the abutment element. The thickness (Z) of the abutment elementmay bebetween 2 mm -8 mm, such as 6 mm. The length (X) of the abutment element may bebetween 45 mm –60 mm, such as 55 mm. The width (Y) of the abutment element may be between 15 mm –35 mm, such as 30 mm.
[0072] Fig. 3 and fig. 4 schematically illustrates an exemplary a monaural headset 2 according to the invention. The monaural headset 2 is configured to be worn by a user on the user’s head. The headset 2 comprises an ear phone 8, shown in fig. 4, configured to be arranged on a first ear of the user. The headset 2 comprises a headband 12 configured to be arranged on the user’s head. The headband 12 is connected to the ear phone 8 in a first end 14, shown in fig. 4, of the headband 12. The headset 2 comprises an abutment element 16 configured to be arranged on the user’s headin the area of the second ear of the user. The abutment element 16 is connected to the headband 12 in a second end 20 of the headband 12. The abutment element 16 is connected to the headband 12 via a pivotable element 22. The pivotable element 22 is arranged at the abutment element 16.
[0073] Fig. 3 further shows that the abutment element 16 comprises an abutment surface 24 adapted to abut to the user’s head, when the headset 2 is worn in its intended position. The pivotable element 22 is arranged at the abutment element 16 at a minimal distance L3 from the abutment surface 24 of the abutment element 16.
[0074] The minimal distance L3 may be between 2.0 mm –2.4. mm, such as between 2.1 mm –2.3 mm, such a 2.2 mm.
[0075] The pivotable element 22 is arranged at a minimal distance L3 from the abutment surface 24 of the abutment element 16 for ensuring that the pivotable element 22 between the abutment element 16 and the headband 12 is as close to the user’s head as possible.
[0076] The pivotable element 22 between the abutment element 16 and the headband 12 is provided as close to the user’s head as possible for ensuring even pressure distribution of the headset 2 on the user’s head.
[0077] Fig. 3 and fig. 4 further show that the pivotable element 22 is arranged at the centre of the abutment element 16. The centre of the abutment element may be defined as the center of mass of the abutment element, or as a geometrical center, or as a structural center of the abutment element etc. The abutment element may be shaped as a circle, or as an oval, or as a rectangle, or as a square etc.
[0078] It is an advantage that the pivotable element is arranged at the centre of the abutment element, because this may provide a more evenly pressure distribution of the headset on the user’s head.
[0079] The pivotable element 22 comprises a ball-joint.
[0080] The abutment element 16 comprises a first part 26 facing towards the headband 12, wherein the pivotable element 22 is arranged at the first part 26. The element 16 comprises a second part 28 at the abutment surface 24 facing towards the user’s head, when the headset 2 is worn in its intended position. The first part 26 may be a rigid plastic part. The second part 28 may be a soft, resilient part.
[0081] The abutment element 16 is attached to the headband 12 by an attachment element 30, e.g. a screw, which is inserted via the abutment element 16 and attached into the headband 12. The attachment element 30 is inserted in a cap 32 in the abutment element 16. The cap 32 is arranged in the first part 26 of the abutment element 16.
[0082] The abutment element 16 may be attached to a base 34 at the headband 12, where the base 34 is an abutment element base 34.
[0083] The abutment element 16 is attached to the headband 12 by the attachment element 30 inserted via the abutment element 16, thus may be inserted through the abutment element 16, such as through a through-hole in the abutment element 16. The abutment element 16 may be attached into the headband 12, such as screwed into the headband 12, e.g. into the base 34 of the headband 12, with the attachment element 30, e.g. a screw. The attachment element 30, e.g. the screw, may be fastened at the base 34 of the headband 12 with a nut 36.
[0084] The second part 28 of the abutment element 16 covers the attachment element 30 and the cap 32 in the first part 26 of the abutment element 16.
[0085] The abutment element 16 is configured to rotate about the attachment element 30 and the cap 32 in the abutment element 16 for providing the pivotable element 22.
[0086] Fig. 3 further shows a gap 38 provided between an outer surface of the cap 32 and a surface of the first part 26 of the abutment element 16. The gap is for ensuring free movement of the abutment element 16 relative to the headband 12.
[0087] Fig. 5a, 5b and 5c schematically illustrate the forces applied from the monaural headset 2 to the head 6 of the user 4 wearing the headset 2.
[0088] Fig. 5a schematically illustrates an exemplary a monaural headset 2 according to the invention. The monaural headset 2 is configured to be worn by a user 4 on the user’s head 6. The headset 2 comprises an ear phone8 configured to be arranged on a first ear 40 of the user 4. The headset 2 comprises a headband 12 configured to be arranged on the user’s head 6. The headband 12 is connected to the ear phone 8 in a first end 14 of the headband 12. The headset 2 comprises an abutment element 16 configured to be arranged on the user’s head6 in the area of the second ear 42 of the user 4. The abutment element 16 is connected to the headband 12 in a second end 20 of the headband 12. The abutment element 16 is connected to the headband 12 via a pivotable element 22. The pivotable element 22 is arranged at the abutment element 16.
[0089] Fig. 5c shows that an upside normal force Fn1is approximately equal to a downside normal force Fn2, where the upside normal force Fn1and the downside normal force Fn2are forces of the abutment element 16 on the user’s head 6, when the headset 2 is worn in its intended position, see fig. 5a.
[0090] Thus, the arrangement of the abutment element 16 and the pivotable element 22 in the headset 2, where the pivotable element 22 is arranged at the abutment element 16, providing that the pivotable element 22, and thereby the pivot point between the abutment element 16 and the headband 12, will be closer to the user’s head 6, will ensure that the upside normal force Fn1is approximately equal to the downside normal force Fn2, and this will provide an even pressure distribution of the headset 2 on the user’s head 6.
[0091] Fig. 5a shows that the headset 2 may apply three external forces being a force F1 for the abutment element 16 side, and a force F2 for the ear phone 8 side, and gravity G, to the user’s head 6 to keep balance:
[0092] F1 + F2 + G = 0
[0093] Fig. 5c shows that for the abutment element side, F1 may be divided to the following three parts: f being a frictional force, and Fn1being the upside normal force, and Fn2, being the downside normal force.
[0094] If assuming that the pivotable element 22 is smooth and slippery, i.e. assuming no resistance, then the moment M for the pivotable element is 0, since:
[0095] M = f *l3+ Fn1*l1+ Fn2*l2= 0
[0096] Where l3or L3 is the minimal distance between the pivotable element 22, such as between the centre of the pivotable element 22, and the abutment surface 24 of the abutment element 16, which is measured along the thickness Z of the abutment element 16.
[0097] And where l1is a distance along the width Y of the abutment element 16, measured from the pivotable element 22, which is approximately in the centre of the abutment element 16, and then up to the end of the abutment element 16 along the width.
[0098] And where l2is a distance along the width Y of the abutment element 16, measured from the pivotable element 22, which is approximately in the centre of the abutment element 16, and then down to the other end of the abutment element 16 along the width.
[0099] If l3or L3 is minimal, i.e. l3→0, i.e. l3or L3 assumed to be close to 0, then:
[0100] Fn1*l1+ Fn2*l2= 0
[0101] And thereby:
[0102] Fn1≈ Fn2
[0103] Thus, when the upside normal force Fn1is approximately equal to the downside normal force Fn2, then the pressure distribution from the headset 2 on the user’s head 6 is uniform and even.
[0104] Fig. 5b shows an example of prior art, see also fig. 1, where the prior art monaural headset has a headband and a T-bar (an example of an abutment element) , and where the T-bar is connected to the headband via a ball-joint (an example of a pivotable element) , and where the ball-joint is arranged in the headband.
[0105] As seen from fig. 5b, in prior art, the distance l3is bigger than in the present invention, thus the distance l3is not approximately 0, and thereby the upside normal force Fn1is not approximately equal to the downside normal force Fn2, and thereby the pressure distribution from the headset on the user’s head is not uniform and not even. Thus, the advantage of an even pressure distribution is not obtained by the prior art, as shown in fig. 5b.
