Definitions
- the present invention relates to isolated wires and especially lead wires used in connection with headsets and hearing devices.
- Isolated wires and lead wires comprising a multiple number of conducting sub wires are widely used in connection with electronics where a multiple number of electric signals need to be transmitted from one place to another.
- the sub wires are typically constructed by twisting a number of thin cables of a conducting material (e.g. copper), and each sub wire are hereafter isolated by covering the twisted cables with a non-conducting jacket typically formed by plastic (e.g. Pebax).
- the sub wires are hereafter collected in a bundle and the bundle is subsequently covered with a second non-conducting jacket. The result is that the sub wires are isolated from each other and it is therefore possible to transmit different electrical signals through the sub wires.
- Headsets and hearing devices often comprise an ear side unit placed behind the ear and a receiver (loudspeaker) placed in or near the ear channel.
- the ear side unit comprises, in connection with hearing devices, a number of microphones for detecting sounds and data handling and amplifier units for data handling and amplification of the sound signals recorded by the microphone.
- the data handled and amplified sound signals are hereafter transmitted to the receiver through lead wires drawn from the ear side unit to the receiver where the sound signals would be converted into sounds waves inside the ear channel and thereby improving the user's listening skills.
- the ear side unit could for instance comprise a radio receiver for receiving sound signals transmitted as radio waves (FM, AM, Bluetooth etc.) and thereby enable the user to receive and hear sound signals transmitted as radio signals.
- the lead wires connecting the ear side unit and the receiver are today drawn through a sound tube. It is very difficult and time-consuming to draw the lead wires through the sound tube because each lead wire needs to be inserted and drawn/pushed through the sound tube individually. Another issue is the fact that the sound tube is often relatively large and made of a relatively stiff material in order to provide strength to the sound tube. Further, many people want to have a very discreet and comfortable device and finds that the sound tube is both indiscreet and annoying to wear. The sound tube is therefore produced as small as possible thus complicating the production process further.

- Figure 1 illustrates an embodiment of an isolated wire (101) according to the present invention.
- the isolated wire comprises a number of lacquered conducting wires (103a, 103b, 103c), a strength fiber (105) and a flexible isolation outer isolating jacket (107).
- the lacquered conducting wires (103a, 103b, 103c) and the tensile strength fiber (105) are twisted together (see fig.
- the outer isolating jacket (107) is stripped off the twisted lacquered conducting wires in both ends of the isolated wire, and the lacquered conducting wires are also separated in both ends. The ends can therefore be connected to electrical means, and electrical signals can then be transmitted through each of the lacquered conducting wires.
- the lacquered conducting wires are isolated from each other due to the lacquer that covers the conducting part of the conducting wires. The consequence is that the conducting wires could be isolated from each other without having an outer isolating jacket made of isolating material such as nylon, silicone, polyethylene, PVC, Polyamid, polyester, Pebax, etc. around each conducting wire.
- the outer diameters of the conducting wires are hereby reduced dramatically, and as a result the outer diameter of the isolating wire is reduced even more.
- the flexibility and softness of the isolated wire is further improved as the relatively inflexible and hard outer isolating jackets presently used around conducting wires are omitted.
- the strength fiber improves the strength of the isolated wire, and the strength of the isolated wire could be designed to specific specifications by choosing the material of the strength fibers by regulating the dimensions of the strength fibers or by choosing the number of strength fibers integrated into the isolated wire.
- Another advantage of the present invention is the fact that the isolated wire is less sensitive to noise such as electro mechanical, EM because the lacquered conducting wires are twisted. Summed up, the isolated conducting wire according to the present invention combines flexibility, softness and strength.
- Figure 2 illustrates one end of the isolated wire illustrated in figure 1 without the outer isolating jacket (107). It can be seen that the lacquered conducting wires (103a, 103b, 103c) and the flexible strengthen fiber (105) are twisted together such that they form a helix.
- the stiffness, softness and strength of the isolated wire can be modified to fit different customer specifications by varying the materials and dimensions of the isolated wire or the strength fiber.
- the strength of the isolated wire could for instance be increased by adding more strength fibers (107) by choosing strength fibers made of strong material and/or by increasing the dimensions of the strength fibers or the lacquered conducting wires.
- the strength fibers could for instance be aramid such as kevlar fibers, i.e. a group of heat-resistant and strong synthetic fibers which do not extend in length when stretched.
- FIG 3 illustrates an enlarged view of an embodiment of a lacquered conducting wire (103).
- the lacquered conducting wire comprises in this embodiment a number of thin conducting magnet wires (301a, 301b, 301c) that are twisted together and form a helix.
- Each magnet wire is lacquered individually before they are twisted together.
- the lacquered conducting wire is very flexible and strong as each magnet wire provides strength to the lacquered conducting wire, and since the magnet wires are lacquered individually they can be displaced relatively to each other which results in a flexible conducting wire.
- One or more of the magnet wires could be colored e.g. by using a colored lacquer and thereby forming a tracer (303) for easy identification of the lacquered conducting wire.
- the magnet wires could for instance be lacquered (305, illustrated as spray paint) by pulling the magnet wires through a bath comprising the lacquerer by covering the magnet wire with electrostatic powder which melts when heated or by spray painting.
- the lacquer could for instance be polyamide, polyurethane or the like.
- the lacquered conducting wire thereby forms a litz wire where each magnet wire is lacquered individually.
- Figure 4 illustrates another embodiment of an isolated wire (101 ) according to the present invention and illustrates one end of the wire.
- the twisted lacquered conducting wires (103a, 103b, 103c) and the strengthen fiber have been secured to the outer isolating jacket (107) by adhesive (401 ).
- the isolated wire is hereby made tight because the adhesive would prevent air, moist and dirt from entering the outer jack. This improves the isolated wire against corrosion and excludes further sounds from travelling inside the outer isolating jacket.
- the adhesive (401 ) could further be used to secure the isolated wire to an electronic application e.g. by securing the strength fiber to the application.
- the lacquered conducting wires are in this embodiment tinned (403a, 403b, 403c) at their ends such that it is ensured, in the 5 embodiment, where each lacquered conducting wire comprises a number of individually lacquered magnet wires are twisted together as described in figure 3, that there is an electrical connection between each lacquered magnet wire in the same litz wire.
- the electrical connecting between the lacquered magnet wires could be established by usingo conducting adhesive or by melting the magnet wires together.
- the tinned ends further ensures that each lacquered wire can easily be brazed to an electric application and thereby create a very good contact between the electric application and the isolated wire.
- the isolated wire could for instance be manufactured by lacquering a number of magnet wires, and a number of lacquered magnet wires could be collected in a bundle, where some of the lacquered magnet wires are colored. The bundle of lacquered magnet wires could then be twisted and thus form a lacquered conducting wire which comprises colored magnet wires for o identification purpose. Seven magnet wires are in one embodiment twisted together and two of these magnet wires are colored. However, any number of magnet wires and/or colored magnet wires could in other embodiments be twisted together. After that a number of lacquered conducting wires and a strength fiber could be twisted together, and an outer jacket could be5 extruded around the twisted conducting wires. Three conducting wires with different colored magnet wires are in one embodiment twisted together with an aramid fiber, and the isolated wire thus comprises three lead wires which can be identified by their color.
- FIG. 5a and 5b illustrate a hearing device as known in the prior art, where figure 5a illustrates how the hearing device (501 ) is placed on the ear (503) and figure 5b illustrates the hearing device without the ear.
- the hearing device comprises an ear side unit (505) placed behind the ear, a receiver (507) placed with in the ear channel (509).
- the ear side unit comprises a microphone array (511 ), a battery chamber (513) for power supplying of the hearing device, a volume control (515) enabling the user to turn the volume up and down and a processing and amplifying unit (not shown since it is enclosed).
- the microphones record the sound and convert the acoustic signals into electric signals, and the processing and amplifying unit would hereafter typically filter and amplify the electric signals.
- the processing and amplifying unit could be implemented as analog units, digital units or a combination of both analog and digital units.

- the sound tube comprises a number of lead wires (not shown) drawn through the sound tube.
- the lead wires are connected to the processing and amplifying unit at the ear side unit and to the receiver. Thereby the processed and amplified signals could be transmitted from the ear side unit behind the ear to the receiver inside the ear channel, where the receiver converts the electric signals into acoustic signals.
- the sound tube is made of a relatively flexible material, many people find it difficult to position the hearing device such that the sound tube is not annoying as the tube is made of a relatively hard material and has a relatively large extent. Further, many people find the sound tube indiscreet.

This is also a problem if for instance the receiver, the lead wires or the ear side unit are malfunctioning and need to be replaced. Further, when using the prior art sound tubes there is a possibility that sounds would travel inside the sound tube and result in noise that would reduce the sound quality of the hearing device.

Description
AN ISOLATED WIRE
Field of the invention
The present invention relates to isolated wires and especially lead wires used in connection with headsets and hearing devices.
Background of the invention
Isolated wires and lead wires comprising a multiple number of conducting sub wires are widely used in connection with electronics where a multiple number of electric signals need to be transmitted from one place to another. The sub wires are typically constructed by twisting a number of thin cables of a conducting material (e.g. copper), and each sub wire are hereafter isolated by covering the twisted cables with a non-conducting jacket typically formed by plastic (e.g. Pebax). The sub wires are hereafter collected in a bundle and the bundle is subsequently covered with a second non-conducting jacket. The result is that the sub wires are isolated from each other and it is therefore possible to transmit different electrical signals through the sub wires.
There is a tendency that electronics and especially consumer electronics get smaller and smaller, and therefore scarcity of space often causes problems in connection with electronics. As a consequence, even smaller isolated wires are needed when transmitting electrical signals; however, it is very difficult to construct small isolated wires due to the fact that the sub wires need to be isolated from each other and are therefore covered with a plastic jacket.
Headsets and hearing devices often comprise an ear side unit placed behind the ear and a receiver (loudspeaker) placed in or near the ear channel. The ear side unit comprises, in connection with hearing devices, a number of microphones for detecting sounds and data handling and amplifier units for
data handling and amplification of the sound signals recorded by the microphone. The data handled and amplified sound signals are hereafter transmitted to the receiver through lead wires drawn from the ear side unit to the receiver where the sound signals would be converted into sounds waves inside the ear channel and thereby improving the user's listening skills. In connection with headsets instead of microphones, the ear side unit could for instance comprise a radio receiver for receiving sound signals transmitted as radio waves (FM, AM, Bluetooth etc.) and thereby enable the user to receive and hear sound signals transmitted as radio signals.
The lead wires connecting the ear side unit and the receiver are today drawn through a sound tube. It is very difficult and time-consuming to draw the lead wires through the sound tube because each lead wire needs to be inserted and drawn/pushed through the sound tube individually. Another issue is the fact that the sound tube is often relatively large and made of a relatively stiff material in order to provide strength to the sound tube. Further, many people want to have a very discreet and comfortable device and finds that the sound tube is both indiscreet and annoying to wear. The sound tube is therefore produced as small as possible thus complicating the production process further.

Description of embodiments
Figure 1 illustrates an embodiment of an isolated wire (101) according to the present invention. The isolated wire comprises a number of lacquered conducting wires (103a, 103b, 103c), a strength fiber (105) and a flexible isolation outer isolating jacket (107). The lacquered conducting wires (103a, 103b, 103c) and the tensile strength fiber (105) are twisted together (see fig.
2) and constitute the core part (109) of the isolated wire. The outer isolating
jacket (107) is stripped off the twisted lacquered conducting wires in both ends of the isolated wire, and the lacquered conducting wires are also separated in both ends. The ends can therefore be connected to electrical means, and electrical signals can then be transmitted through each of the lacquered conducting wires. The lacquered conducting wires are isolated from each other due to the lacquer that covers the conducting part of the conducting wires. The consequence is that the conducting wires could be isolated from each other without having an outer isolating jacket made of isolating material such as nylon, silicone, polyethylene, PVC, Polyamid, polyester, Pebax, etc. around each conducting wire. The outer diameters of the conducting wires are hereby reduced dramatically, and as a result the outer diameter of the isolating wire is reduced even more. The flexibility and softness of the isolated wire is further improved as the relatively inflexible and hard outer isolating jackets presently used around conducting wires are omitted. The strength fiber improves the strength of the isolated wire, and the strength of the isolated wire could be designed to specific specifications by choosing the material of the strength fibers by regulating the dimensions of the strength fibers or by choosing the number of strength fibers integrated into the isolated wire. Another advantage of the present invention is the fact that the isolated wire is less sensitive to noise such as electro mechanical, EM because the lacquered conducting wires are twisted. Summed up, the isolated conducting wire according to the present invention combines flexibility, softness and strength.
Figure 2 illustrates one end of the isolated wire illustrated in figure 1 without the outer isolating jacket (107). It can be seen that the lacquered conducting wires (103a, 103b, 103c) and the flexible strengthen fiber (105) are twisted together such that they form a helix. The stiffness, softness and strength of the isolated wire can be modified to fit different customer specifications by varying the materials and dimensions of the isolated wire or the strength fiber. The strength of the isolated wire could for instance be increased by
adding more strength fibers (107) by choosing strength fibers made of strong material and/or by increasing the dimensions of the strength fibers or the lacquered conducting wires. The strength fibers could for instance be aramid such as kevlar fibers, i.e. a group of heat-resistant and strong synthetic fibers which do not extend in length when stretched.
Figure 3 illustrates an enlarged view of an embodiment of a lacquered conducting wire (103). The lacquered conducting wire comprises in this embodiment a number of thin conducting magnet wires (301a, 301b, 301c) that are twisted together and form a helix. Each magnet wire is lacquered individually before they are twisted together. The consequence is that the lacquered conducting wire is very flexible and strong as each magnet wire provides strength to the lacquered conducting wire, and since the magnet wires are lacquered individually they can be displaced relatively to each other which results in a flexible conducting wire. One or more of the magnet wires could be colored e.g. by using a colored lacquer and thereby forming a tracer (303) for easy identification of the lacquered conducting wire. The magnet wires could for instance be lacquered (305, illustrated as spray paint) by pulling the magnet wires through a bath comprising the lacquerer by covering the magnet wire with electrostatic powder which melts when heated or by spray painting. The lacquer could for instance be polyamide, polyurethane or the like. The lacquered conducting wire thereby forms a litz wire where each magnet wire is lacquered individually.
Figure 4 illustrates another embodiment of an isolated wire (101 ) according to the present invention and illustrates one end of the wire. The twisted lacquered conducting wires (103a, 103b, 103c) and the strengthen fiber have been secured to the outer isolating jacket (107) by adhesive (401 ). The isolated wire is hereby made tight because the adhesive would prevent air, moist and dirt from entering the outer jack. This improves the isolated wire against corrosion and excludes further sounds from travelling inside the outer
isolating jacket. The adhesive (401 ) could further be used to secure the isolated wire to an electronic application e.g. by securing the strength fiber to the application. The lacquered conducting wires are in this embodiment tinned (403a, 403b, 403c) at their ends such that it is ensured, in the 5 embodiment, where each lacquered conducting wire comprises a number of individually lacquered magnet wires are twisted together as described in figure 3, that there is an electrical connection between each lacquered magnet wire in the same litz wire. Alternatively, the electrical connecting between the lacquered magnet wires could be established by usingo conducting adhesive or by melting the magnet wires together. The tinned ends further ensures that each lacquered wire can easily be brazed to an electric application and thereby create a very good contact between the electric application and the isolated wire. 5 The isolated wire could for instance be manufactured by lacquering a number of magnet wires, and a number of lacquered magnet wires could be collected in a bundle, where some of the lacquered magnet wires are colored. The bundle of lacquered magnet wires could then be twisted and thus form a lacquered conducting wire which comprises colored magnet wires for o identification purpose. Seven magnet wires are in one embodiment twisted together and two of these magnet wires are colored. However, any number of magnet wires and/or colored magnet wires could in other embodiments be twisted together. After that a number of lacquered conducting wires and a strength fiber could be twisted together, and an outer jacket could be5 extruded around the twisted conducting wires. Three conducting wires with different colored magnet wires are in one embodiment twisted together with an aramid fiber, and the isolated wire thus comprises three lead wires which can be identified by their color.
o Figure 5a and 5b illustrate a hearing device as known in the prior art, where figure 5a illustrates how the hearing device (501 ) is placed on the ear (503)
and figure 5b illustrates the hearing device without the ear. The hearing device comprises an ear side unit (505) placed behind the ear, a receiver (507) placed with in the ear channel (509). The ear side unit comprises a microphone array (511 ), a battery chamber (513) for power supplying of the hearing device, a volume control (515) enabling the user to turn the volume up and down and a processing and amplifying unit (not shown since it is enclosed). The microphones record the sound and convert the acoustic signals into electric signals, and the processing and amplifying unit would hereafter typically filter and amplify the electric signals. The processing and amplifying unit could be implemented as analog units, digital units or a combination of both analog and digital units. The ear side unit is through a sound tube (517) connected to the receiver placed in the ear channel. The sound tube comprises a number of lead wires (not shown) drawn through the sound tube. The lead wires are connected to the processing and amplifying unit at the ear side unit and to the receiver. Thereby the processed and amplified signals could be transmitted from the ear side unit behind the ear to the receiver inside the ear channel, where the receiver converts the electric signals into acoustic signals. Even though the sound tube is made of a relatively flexible material, many people find it difficult to position the hearing device such that the sound tube is not annoying as the tube is made of a relatively hard material and has a relatively large extent. Further, many people find the sound tube indiscreet. Another problem with the prior art sound tubes is the fact that the lead wires need to be drawn/pushed through the sound tube individually, which is a very time-consuming process which therefore increases the production costs. This is also a problem if for instance the receiver, the lead wires or the ear side unit are malfunctioning and need to be replaced. Further, when using the prior art sound tubes there is a possibility that sounds would travel inside the sound tube and result in noise that would reduce the sound quality of the hearing device.
Figure 6a illustrates a hearing device where an isolated wire (101 ) according to the present invention has been used to connect the ear side unit (not shown) and the receiver (507), and figure 6b illustrates an exploded view of the same hearing device. The isolated wire (101 ) is embodied as a soft and flexible isolated wire by using soft and flexible materials for the lacquered conducting, the strength fibers and the outer isolating jacket and each lacquered conducting wires have been made as described in figure 3. The user therefore finds the hearing device nice to wear, and the isolated wire is further very discreet and could for instance be painted/dyed in skin color.
In the shown embodiment the isolated wire further comprises an ear side stiffener (601) formed as a stiff tube that is curved such that it fits around the upper part of the ear and fastened to the ear side unit. The isolated wire (101 ) is drawn through the ear side stiffener (601) and enters the ear side unit where it is connected to the electrical means. The ear side stiffener would therefore be able to fixate the ear side unit behind the ear. The isolated wire further comprises a receiver side stiffener (603) formed as a stiff tube connected to a receiver housing (605) surrounding the receiver (507) and curved to fit the entrance of the ear channel such that the receiver housing could be fixated inside the ear channel. Summed up, the isolated wire comprises an ear side stiffener (601 ) fixating the ear side unit behind the ear, a receiver side stiffener (603) fixating the receiver housing (605) inside the ear channel and a soft and flexible part of the isolated wire part (607). The isolated wire could for instance be connected to the ear side unit or receiver by using adhesive or by designing an electrical connector.
It is to be understood that the illustrated embodiments only serve as illustrating examples rather than limiting the scope of the claims. A person skilled in the art may be therefore able to construct alternative embodiments within the scope of the claims.
