Earphone with transparent cover plate for sheet insert
Technical Field
The invention relates to an earphone, such as a headset or a behind-the- ear hearing aid, comprising at least one earpiece with an earpiece housing and holding means for holding the housing against the ear of the user, wherein the housing comprises a releasably mounted cover plate. By the term earphone is here meant different types of devices, which are worn on, in or at the ear, and which converts electrical energy into sound waves that are directed to the auditory canal. The invention especially relates to a headset which comprises at least one earphone and a microphone and which can be used as a two-way communication device, e.g. with a mobile phone.
Background Art
US 4,292,481 discloses a push-button telephone with a transparent faceplate assembly into which a decorative "applique" can be inserted so that a decorative design is visible. It is also known to provide a mobile phone with an exchangeable cover so that the owner easily can change the appearance of the mobile phone. DE 201 04 24 U 1 discloses a mobile phone with a transparent cover plate behind which "1 paper inserts with different designs or patterns can be arranged. Headsets with exchangeable coloured cover plates are also known.
Disclosure of Invention
An earphone is worn on, in or at the user's ear and has in most cases an effect on the overall appearance of the user. Hearing devices and in some cases mobile phone headsets are often worn all day. Under these
circumstances, the appearance of the earpiece is important for the most users. Therefore, there is a need to improve the possibilities of changing the appearance of an earpiece.
The earphone according to the invention is characterised in that the cover plate is transparent and that an exchangeable sheet insert is positioned under the cover plate such that the sheet insert is visible from the outside. In this way, the user can customize the appearance of the earpiece in seconds by removing the cover plate, exchanging the sheet insert and mounting the cover plate again. The sheet inserts can be pieces of paper with different decorations supplied with the earphone. In addition, the earpiece can be supplied with sheets of paper, which are partly cut out or punched along lines defining the outline of separate paper inserts. The user can make his own design on his computer and print the paper sheets with his conventional computer printer. Off course, different designs, patterns, ornaments, drawings, photographs, advertisings, trademarks, words, names, cartoon characters, national flags etc. can be printed on the paper sheet inserts.
According to an embodiment of the invention, the housing has a first wall facing the ear of the user and a second wall facing away from the ear, wherein the cover plate is mounted on or in the second wall. In this way, the most visible wall comprises the cover plate.
The cover plate is preferably mounted in a recess on the outside of the second wall, which recess has an outline corresponding to the outline of the transparent cover plate. The inner side of the cover plate and the bottom of the recess define preferably a narrow space that accommodates the sheet insert. In this way, the sheet insert can be held firmly without being curled or wrinkled.
The outside of the cover plate is advantageously flush with the outside of the second wall in the area around the recess. In this way, a smooth overall surface of the headset is obtained.
According to an embodiment, the earpiece and the cover plate are oblong, wherein the cover plate extends between a first end and a second end in a longitudinal direction and is fastened to the second wall at the two ends.
According to an embodiment, the cover plate comprises a resilient locking leg, which extends perpendicularly from the inner side of the cover plate at the second end, which resilient leg at the distal end comprises a detent that engages an edge of a locking hole in the second wall.
Preferably, a fingernail notch is provided in the edge of the recess at the second end of the cover plate, such that a fingernail can apply a bending force to the resilient locking leg and release the detent from engagement with the edge of the locking hole in order to release the cover plate. In this way, a simple and reliable releasable fastening of the cover plate may be obtained.
Preferably, the first end of the cover plate partly engages an undercut in the edge of the recess.
A button may extend out through a hole in the sheet insert and a hole in the cover plate.
The holding means may comprise an earhook. Alternative holding means are headband, neckband, concha engaging means, auditory canal engaging means (also called ear buds).
The earhook can be mounted, preferably adjustably, to the first wall of the earpiece housing.
The cover plate can be made of plastics.
The invention also relates to a headset comprising at least one earphone, which headset is a two-way communications device comprising a microphone.
The headset can be a wireless headset, e.g. a Bluetooth headset.
The headset may comprise only one earpiece.
The invention also relates to a so-called behind-the-ear hearing aid comprising an earpiece that is worn behind. the ear. It is connected to a plastic ear mould that fits snugly in the outer ear. Such a hearing aid is known from WO 99/04601 A1.

Best Mode for CarrvinĪ± out the Invention
Fig. 1 discloses a headset 19 according to a preferred embodiment of the invention. The headset is a wireless headset to be used with mobile
phones. The headset 1 comprises an earpiece 1 with an earpiece housing 2 and an earhook 5 to be positioned behind the pinna of the ear and by means of which the earpiece 1 can be held against the auditory canal of the users ear. The earpiece housing 2 has a first wall 3 facing the ear of the user during use and a second wall 4 facing away from the ear. The earhook 5 is adjustably mounted to the first wall 3 of the earpiece housing 2. The first wall 3 comprises a speaker opening (not shown), which preferably is arranged in the free end of a protrusion to be inserted into the concha. The second wall 4 turns away from the ear during use and is normally visible for other persons looking at the user. A button 9 for operating the headset is arranged in the second wall 4. The leftmost end of the earpiece 1 is provided with a microphone 14. Thus, the microphone 14 is arranged in the part of the headset, which is closest to the mouth of the user and farthest away from the speaker.
Figs. 2 to 4 disclose how the appearance of the headset according to Fig. 1 can be changed. The second wall 4 comprises a recess 7 in which a transparent cover plate 6 is releasably mounted. As shown in Fig. 1 , the outside of the cover plate 6 is flush with the outside of the second wall 4 in the area around the recess 7, whereby the complete outer surface appears smooth. A paper insert 8 is arranged between the bottom of the recess 7 and the inner side of the cover plate 6. The paper insert is visible through the transparent cover plate 6 and is arranged for decorative, commercial or information purposes. A first end 15 of the cover plate 6 engages partly an undercut (not shown) in the edge of the recess 7. For this purpose, the first end 15 of the cover plate 6 may comprise a small protrusion that engages an edge of the recess 7. As shown in Fig. 5 and 6, the opposite end 16 of the cover plate 6 is provided on the inner side with a resilient locking leg 12 with a detent 13 that engages an edge of a locking hole 20 in the second wall 4 (see Fig. 4). The paper insert 8 is provided with a notch 21 to allow passage of the locking leg 12. A fingernail notch 17 is provided in the edge
of the recess 7 such that a fingernail can apply a bending force to the resilient leg 12 in order to release the cover plate 6. The arrow A shows where and in which direction the fingernail is inserted and pushed in order to release the detent from the edge of the locking hole 20 and thereby release the cover plate 6. The cover plate 6 and the paper insert 8 are provided with respective holes 10, 11. The shape of the holes 10, 11 correspond to the shape of the button 9.
Fig. 2 shows the cover plate 6 just after it has been released from the earpiece housing 2 and after it has been lifted in order to exchange the paper insert 8. Fig. 3 shows the headset 1 after the removal of the cover plate 6 and the paper insert 8 in the direction of the arrow B. Fig. 4 shows the headset 1 after a paper insert 18 with a different pattern printed thereon has been positioned in the direction of the arrow C in the recess 7.
The invention is not limited to the above embodiment. Stereo headphones comprising two earphones and behind-the-ear hearing aids are also covered by this application.
