[0001] E LECTRON IC EYEG LASS SET

[0002] TECH N ICAL FI ELD

[0003] The present invention relates to the field of electronic eyewear, and in particular to electronic eyeglasses with integrated electronic components, and methods of manufacturing the same.

[0004] BACKG ROU N D

[0005] Advances in technology has resulted in advanced electronics being available in eyeglasses, e.g., smart glasses, head mounted displays, etc. These electronic eyeglasses have gained significant attention in recent years due to their potential to provide users with a wide range of functionalities. These eyeglasses may be equipped with electronics of various types, including electronic displays, electronic see- through displays, audio transmitters, microphones, user interface controllers, cameras, etc. As a result, electronic eyeglasses have the potential to revolutionize the way people interact with their environment and access information.

[0006] For example, there are electronic eyeglasses presenting augmented reality, electronic eyeglasses presenting virtual reality, and electronic eyeglasses having lenses for protection or for correcting the vision of the user. The two latter types do not necessarily include electronics for making visual presentations to the user via displays or the like, however information may be conveyed using audio, vibrations, lights etc. They may accordingly include electronics for controlling and communicating with other devices, indicators, sensors, and / or cameras. Some examples of electronic eyeglasses are Vuzix Blade 2, Vuzix Shield, Ray-Ban Meta Smart Glasses, etc.

[0007] However, there are several challenges associated with the design and manufacturing of electronic eyeglasses. One of the primary challenges is fitting the electronics into the hardware of the eyeglasses while maintaining a comfortable and functional design for users. Traditional eyeglasses can be easily adjusted by an optician to fit the user's head size and shape, but electronic eyeglasses may require more complex mechanisms to accommodate different users. Additionally, the integration of advanced electronics into the eyeglasses may result in increased weight and bulk, which can negatively impact user comfort and wearability.

[0008] Another challenge is the need for electronic eyeglasses to be easily adjustable and adaptable to fit a wide range of users with varying head sizes and shapes. Some known electronic eyeglasses and headsets use adjustable straps to secure the device to the user's head, such as the Meta Quest 2 by Meta or the HoloLens 2 by Microsoft. However, these solutions may not provide the same level of comfort and fit as traditional eyeglasses and may not be suitable for all users.

[0009] In summary, there is a need for electronic eyeglasses that can effectively integrate advanced electronics into a comfortable and functional design, while also being easily adjustable and adaptable to fit a wide range of users with varying head sizes and shapes.

[0010] SU MMARY

[0011] One object of the present invention is to provide an alternative solution to custom fitting of electronic eyeglasses to a user.

[0012] The invention is defined by the appended independent claims. Additional features and advantages of the concepts disclosed herein are set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the described technologies. The features and advantages of the concepts may be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the described technologies will become more fully apparent from the following description and appended claims or may be learned by the practice of the disclosed concepts as set forth herein.

[0013] According to a first aspect, there is provided an electronic eyeglass set comprises a middle section, as well as a first temple and a second temple each connected to the middle section. The middle section may be a rim. The middle section may be configured to hold one or more lenses and / or one or more displays.

[0014] The first temple has a connected section connected to the middle section and a tip section. The electronic eyeglass set includes a first printed circuit board arranged in the connected section of the first temple and a second printed circuit board arranged in the tip section of the first temple. The first temple further includes a pliable section located between the connected section and the tip section, the pliable section including an elongated metal element. The first and second printed circuit boards are electrically connected via the pliable section.

[0015] This configuration allows for a compact and sleek design of the eyeglasses, provides advanced electronic functionalities to the electronic eyeglass set. Furthermore, this configuration also allows the eyeglass set to be manually adjustable to fit different users while still providing a rigid and strong temple that does not deform during use.

[0016] In some embodiments, the second printed circuit board includes electronics for transfer of audio via bone conduction, for example via a bone conducting transducer which may be connected to and / or controlled by the second printed circuit board. This feature allows the eyeglasses to transmit audio to the user through bone conduction, providing a comfortable and non-intrusive way for the user to receive audio information. Another advantage of having the combination of the two separate printed circuit boards and the arrangement of the pliable section including the elongated metal element in combination with electronics for transferring audio via bone conduction is that the pressure of the bone conduction apparatus against the skull of the user may be adjusted for comfort and increased audio quality.

[0017] In some embodiments, the elongated metal element forms at least one electrically conducting line between the first printed circuit board and the second printed circuit board. The electrically conducting line may be a signal line for carrying an electrical signal between the two printed circuit boards. Thus, the elongated metal element provides efficient electrical communication between the two circuit boards.

[0018] In some embodiments, the elongated metal element supports one or more electrically conducting lines between the first printed circuit board and the second printed circuit board. The electrical lines may be configured to carry electrical communication between the first printed circuit board and the second printed circuit board. Thus, the elongated metal element provides structural support to the electrically conducting lines reducing the risk of damage to the lines. For example, the electrically conducting lines may be wound around the elongated metal element. Accordingly, when the pliable section (and the elongated metal element therein) is bent or adjusted, the wound electrically conducting lines are arranged at an angle to the direction of the elongated metal element and thereby resulting in a reduced bending of the electrically conducting lines. The stress (e.g. bending stress and / or tension) experienced by the electrically conducting lines may thus be reduced.

[0019] As another example, the elongated metal element may be a metal tube and the electrically conducting lines may be arranged inside the metal tube, that is, in the lumen of the tube. The tubular elongated metal element thus provides a protective housing for the conducting lines, and the electrically conducting lines may run freely through the tubular element thus reducing the risk of damage. A further advantage of this configuration is that signals sent via the electrically conducting lines may be less affected by electromagnetic interference. In other words, the electrically conducting lines may be shielded from electromagnetic interference.

[0020] In some embodiments, the first temple and / or the second temple is made from a material selected from a group comprising: cellulose acetate, plastic, polyamide, nylon, polycarbonate, carbon, and carbon fiber. In particular, the first and / or second temple may be made from cellulose acetate. These materials provide durability and flexibility to the eyeglasses, enhancing their comfort and fit.

[0021] In some embodiments, the electronic eyeglass set further includes a cavity formed in the first temple to accommodate the first printed circuit board, the second printed circuit board, the elongated metal element, and / or one or more other electronic components. The cavity may be formed by milling, allowing for precise and accurate creation of the cavity, enhancing the fit and arrangement of the electronic components within the eyeglasses.

[0022] In some embodiments, the electronic eyeglass set further includes an antenna driving circuit configured to drive the elongated metal element to function as an antenna. The eyeglasses may thus be able to transmit and receive signals through the antenna, enhancing their communication capabilities while maintaining a light weight and slim design. The antenna driving circuit is connected to the elongated metal element to allow it to function as an antenna. The antenna driving circuit may be connected to the first printed circuit board and / or the second printed circuit board to allow efficient control of the antenna function by the circuit boards.

[0023] In some embodiments, the electronic eyeglass set further includes a light source. The light source may be located on an inner side of the first temple, the inner side being a side closest to the middle section and / or a side facing the second temple when the temples are arranged perpendicular to the middle section. The light source may be configured to provide visual cues to the user, thus enhancing the user experience.

[0024] The light source may be located in the connected section of the first temple. Additionally, or alternatively, the light source may be located closer to an end of the first temple connected to the middle section than to an opposite end of the first temple near the tip section. For example, the light source may be arranged within 4 centimeters, optionally 3 centimeters, optionally 2 centimeters, optionally 1 centimeter, from the end of the first temple connected to the middle section.

[0025] The light source may be at least partially embedded in the first temple. This configuration provides a sleek and stylish appearance to the eyeglasses, while ensuring efficient light emission.

[0026] The light source may be any suitable light source. For example, the light source may be a light emitting diode (LED). This type of light source provides bright and efficient light emission while having a low power consumption.

[0027] The electronic eyeglass set may further include a light control circuit configured to control the light source, e.g. by sending one or more control signals to the light source. The light source may thus be precisely controlled. The control signals may, for example, include signals for controlling activation, deactivation, intensity, and / or colour of the light source. Accordingly, a wide range of visual cues may be provided by the eyeglasses, enhancing the user experience. The light control circuit may be connected to the first printed circuit board and / or the second printed circuit board, allowing efficient control of the light source by the circuit boards.

[0028] In some embodiments, the electronic eyeglass set comprises a plurality of light sources. For example, a first light source may be located on the first temple and a second light source may be located on the second temple. Thus, the eyeglass set may provide symmetrical visual cues to the user, providing a more intuitive user experience. By having light sources on both temples, visual cues given by the light sources may also be used to indicate direction, e.g. left or right, to the user.

[0029] Alternatively, or additionally, there may be provided a plurality of light sources on the first and / or second temple. The plurality of light sources may be arranged along the temple, that is, at different distances from the end of the first temple connected to the middle section.

[0030] It will be appreciated that in some embodiments only the first or second printed circuit board may be provided in the first temple.

[0031] According to a second aspect, there is provided an electronic eyeglass set comprising: a first temple and a second temple each connected to a middle section, and a light source arranged on the inner side of the first temple. The middle section and the first and second temple may be substantially similar to the middle section and the first and second temple according to the first aspect. The light source may be substantially similar to the light source of the first aspect. It will further be appreciated that other features of the first aspect are combinable with the second aspect, e.g. a first and / or second printed circuit board being arranged in the first temple, and / or the electronic eyeglass set comprising a light control circuit.

[0032] According to a third aspect, there is provided an electronic eyeglass set comprising: a first temple and a second temple each connected to a middle section, a printed circuit board arranged in the first temple, an elongated metal element arranged in the first temple, and an antenna driving circuit electrically connected to the elongated metal element for driving the elongated metal element to function as an antenna. The middle section and the first and second temple may be substantially similar to the middle section and the first and second temple according to the first and / or second aspect. The elongated metal element may be substantially similar to the elongated metal element of the first and / or second aspect. The antenna driving circuit may be substantially similar to the antenna driving circuit of the first and / or second aspect. It will further be appreciated that other features of the first and / or second aspect are combinable with the third aspect, e.g. a second printed circuit board being arranged in the first temple.

[0033] According to a fourth aspect, there is provided a method of manufacturing an electronic eyeglass set. The method includes: providing a middle section; providing a first temple and a second temple made from cellulose acetate; creating a cavity in the first temple; arranging one or more electronic elements in the cavity; and assembling the electronic eyeglass set by attaching the first temple and the second temple to the middle section. The method allows for efficient and precise manufacturing of the eyeglasses. The cavity may be formed by milling which allows precise and accurate creation of the cavity, enhancing the fit and arrangement of the electronic components within the eyeglasses.

[0034] The one or more electronic elements may further be fastened in the cavity using an adhesive. This ensures a secure placement of the electronic components within the eyeglasses, enhancing their durability and functionality.

[0035] The method may further include filling the cavity with a filler material. The filler material may be a material selected from a group comprising: silicone gel, cellulose acetate, thermoplastic elastomer, polyurethane-based material, rubber compound, gel-like material, resilient material, and resin or adhesive. Alternatively, or additionally, the method may further include sealing the cavity with a lid. This feature provides a secure and protective housing for the electronic components, enhancing the durability and functionality of the eyeglasses. In some embodiments the electronics is reinforcing the temple, in particular the printed circuit board reinforces the temple for increased stability and / or rigidity.

[0036] Optionally, the filler material is configured to, when applied in the cavity, adopt a shape that conforms to the electronic component.

[0037] Optionally, the filler material is formable and / or malleable during filling of the cavity. For example, the filler material may be sufficiently soft or pliable to allow it to conform to the electronic component. For example, the filler material may be at least partly in molten and / or liquid form so as to allow the filler material to at least partly flow into the cavity. For example, the filler material may be a 3D printable material that can be deposited in the cavity by a 3D printing method.

[0038] Optionally, the filler material is in contact with the electronic component arranged in the cavity so as to secure the electronic component in its place within the cavity.

[0039] Optionally, the method further comprises a step of allowing the filler material to set, harden, and / or cure, after the cavity has been filled with the filler material.

[0040] Optionally, the cavity is at least partially formed in a curved portion of the temple. Optionally, the temple is shaped to form a curved portion before the cavity is formed. For example, the method may comprise forming a temple with a temple shape including a curved portion, and subsequently forming the cavity in the curved portion.

[0041] Further scopes of applicability of the present invention will become apparent from the detailed description given below.

[0048] DETAI LED DESCRIPTION

[0049] Hereinafter, certain embodiments will be described more fully with reference to the accompanying drawings. It will be apparent to those skilled in the art that various modifications and variations can be made without departing from the inventive concept. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice disclosed herein. The embodiments herein are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept, and that the claims be construed as encompassing all equivalents of the present inventive concept which are apparent to those skilled in the art to which the inventive concept pertains. If nothing else is stated, different embodiments may be combined with each other. The present invention relates to eyeglasses to provide a user with a variety of functionalities, including but not limited to, visual display, audio output, and wireless communication. The eyeglasses are arranged to deliver information to a wearer using audio signals and / or light signals and to operate as a control interface for some tasks, in some specific embodiments for controlling a device from which the audio signals originate.

[0050] Figs. 1-3 show an electronic eyeglass set according to embodiments. The electronic eyeglass set includes a middle section 10, and a first temple 14 and second temple 16 connected to the middle section 10.

[0051] The middle section 10 may be a rim 11 configured to hold one or more lenses 12 (e.g. vision correction lenses or see-through lenses) or displays (e.g. electronic displays, electronic see-through displays, or the like). The middle section 10 may alternatively be formed of a lens 12 or display, such that the temples 14,16 are connected to the lens 12 or display directly.

[0052] When the eyeglass set is worn by a user, the middle section 10 is designed to be at least partially arranged in front of the eyes of the user. This positioning allows the user to view the display or through the lenses while wearing the electronic eyeglass set. The first temple 14 and the second temple 16 are connected to the middle section 10 and are designed to extend along the sides of the user’s head and may rest on the ears of the user, thereby securing the electronic eyeglass set in place in a similar manner as traditional eyeglasses. The temples 14,16 may be connected to the middle section 10 via a hinge to allow the temples 14,16 to pivot relative to the middle section 10, as is typical for traditional eyeglasses. The second temple 16 may be similar in design and function to the first temple 14.

[0053] The middle section 10 of the electronic eyeglass set may be made from a material that is durable, lightweight, and comfortable for the user. The material can be selected from a variety of options, including but not limited to, plastic materials such as polyamide, nylon, and polycarbonate, or other materials such as carbon, carbon fiber, or cellulose acetate.

[0054] At least one of the first and second temples 14,16 may comprise a connected section 13, a tip section 15, and a pliable section 17. The connected section 13 is the section or portion of the temple 14,16 that is connected to the middle section 10. The tip section 15 is located at an opposite end of the temple 14,16 compared to the connected section 13, that is near the tip of the temple 14,16. The pliable section 17 is located between the connected section 13 and the tip section 15. The pliable section 17 is made from a pliable material to allow the temple shape to be manually adjusted.

[0055] At least one of the first and second temples 14,16 may comprise a first printed circuit board 26 arranged in the connected section 13 and a second printed circuit board 19 arranged in the tip section 15. In some embodiments, at least one of the first and second temples 14,16 only includes one of the first and second printed circuit boards 19,26.

[0056] The first and second printed circuit boards 19,26 may be arranged or housed inside the temple 14,16. In other words, the printed circuit boards 19,26 may be enclosed in the temple 14,16. By arranging the printed circuit boards 19,26 in the temple 14,16 like this, the printed circuit boards 19,26 may reinforce the temple 14,16 and provide increased stability to the eyeglasses.

[0057] The first and / or second printed circuit board 19,26 may include or be connected to one or more electronic components of the electronic eyeglass set. These electronic components can include a variety of devices or features such as one or more micro controllers 20, one or more communication interfaces such as wireless communication interfaces 22, one or more batteries 24, one or more user interfaces (e.g. touch controls or pushbuttons) for controlling the electronics of the eyeglass set, one or more visual indication means (e.g. a light source), one or more speakers, one or more microphones, one or more bone conduction transducers 18, one or more control circuits, one or more interfaces for controlling a device connected to the eyeglasses, or the like. In particular, one or more microphones may allow the electronic eyeglasses to capture audio input from the user or the surrounding environment, enabling the user to make voice commands or conduct voice calls using the electronic eyeglasses. In particular, one or more user interfaces, which can be, for example, a pushbutton or touch control, may allow the user to easily control the electronics of the eyeglasses. In particular, one or more batteries 24 may provide power to the other electronic components of the eyeglasses. In particular, one or more communication interfaces may enable seamless connectivity with other devices for data transfer and communication. In particular, one or more microcontrollers may control the operation of the other electronic components of the eyeglasses.

[0058] Furthermore, at least one of the first and second temples 14,16 may include an elongated metal element 40 arranged in the pliable section 17 between the first printed circuit board 26 and the second printed circuit board 19. The pliable section 17, together with the elongated metal element 40 arranged therein, is designed to allow for manual adjustment of the temple shape. This provides flexibility for fitting different head sizes and shapes. Despite its flexibility, the pliable section 17 together with the elongated metal element 40 maintains its shape during normal use, thereby reinforcing the temple's stability. In particular, the elongated metal element 40 arranged in the pliable section 17 helps to reinforce the temple 14,16 and provide increased stability to the electronic eyeglass set.

[0059] This elongated metal element 40 may be a metal wire, a metal rod, a metal tube, or the like. The elongated metal element 40 is pliable to such a degree that the elongated metal element 40 allows adaption of the shape of the temple 14,16 by hand and without the shape of the temple 14,16 changing during normal use of the eyeglasses.

[0060] According to some embodiments the elongated metal element 40 have the characteristics of being possible to plastically deform, i.e. bent, using a force that may be applied by hand by a person. Hence, the elongated metal element 40 shows low to none elastic recovery when deformed or bent by hand to a desired shape. In some embodiments, the characteristics of the elongated metal element 40 is that it includes a yield point, i.e. the strength required to have the deformation of the metal element 40 transition from elastic to plastic, that is low enough to be overcome by hand, i.e. by a human applying force by hand to the temple including the elongated metal element 40. The elongated metal element 40 may, according to some embodiments, be described as being possible to deform continuously and permanently in any direction.

[0061] The elongated metal element 40 may have a thickness or diameter of 0.5 to 2 mm.

[0062] The combination of the two printed circuit boards 19,26 and the elongated metal element 40 reinforces essentially the full length of a temple 14,16 in combination of enabling adjustment of the temple 14,16 to proper fit an individual wearing the eyeglasses.

[0063] The first printed circuit board 26 and the second printed circuit board 19 are electrically connected via the pliable section 17. For example, the first printed circuit board 26 and the second printed circuit board 19 are connected via electrically conducting lines (not shown). The electrically conducting lines may also be referred to as signal lines and are configured to transport electrical signals and / or power between the two circuit boards 19,26.

[0064] The elongated metal element 40 may form at least one of the electrically conducting lines. That is, the elongated metal element 40 may be electrically conducting and connected to the first printed circuit board 26 and the second printed circuit board 19.

[0065] Additionally, or alternatively, the elongated metal element 40 is configured to support one or more electrically conducting lines between the first printed circuit board 26 and the second printed circuit board 19. The structural support from the elongated metal element 40 reduces the risk of damage to the lines.

[0066] For example, the electrically conducting lines may be wound around the elongated metal element 40, e.g. the electrically conducting lines may form a helix around an outer surface of the elongated metal element 40. The wound electrically conducting lines may further have a freedom of movement relative to the elongated metal element 40. For example, when the elongated metal element 40 is bent or curved, the pitch (e.g. distance of one complete turn, measured parallel to the longitudinal axis of the elongated metal element 40) of the wound electrically conducting lines may be smaller on an inner side of the curved elongated metal element 40 than on an outer side of the curved elongated metal element 40. Thus, the electrically conducting lines do not experience a significant bending or tension stress. The risk of damage to the electrically conducting lines is thus reduced.

[0067] As another example, the elongated metal element 40 may be a tube and the electrically conducting lines may be arranged inside the tube, that is, in the lumen of the tube. The tubular elongated metal element 40 thus provides a protective housing for the conducting lines, and the electrically conducting lines may run freely through the tubular element (i.e. not being attached or fastened to an inside surface of the tubular element), thus reducing the risk of damage.

[0068] Furthermore, by arranging the electrically conducting lines inside the tubular elongated metal element 40, the signals carried by the electrically conducting lines may be shielded from, for example, electromagnetic interference.

[0069] The electric eyeglass set may further comprise one or more bone conducting transducers 18. The bone conducting transducer 18 is designed to transmit audio to a user of the electronic eyeglass set using bone conducting technology. This technology provides a comfortable and non-intrusive way for the user to receive audio information. The bone conducting transducer 18 does not block or obstruct the user's ears, allowing them to maintain awareness of their surroundings. The bone conducting transducer 18 transmits audio directly to the user's inner ear, resulting in clear and crisp sound quality.

[0070] The bone conducting transducer 18 is preferably located in the pliable section 17 or tip section 15 of at least one of the first and second temples 14,16 such that it can transmit audio directly to the user’s inner ear through bone conducting technology. In some embodiments both the first and the second temple 14,16 include a bone conduction transducer 18 arranged to transmit audio to a user of the eyeglasses using bone conducting technology.

[0071] The bone conducting transducer 18 is preferably connected to the second printed circuit board 19, such that the second printed circuit board 19 is configured to control the bone conducting transducer 18.

[0072] Because the temples 14,16 according to embodiments comprise a pliable section 17 together with an elongated metal element 40, the temples 14,16 may be easily adjusted by the user to provide appropriate pressure by the bone conduction transducer 18 against the skull of a user to enable improved audio transfer.

[0073] Embodiments thus allow a speaker, in the form of a bone conducting transducer 18, to be integrated seamlessly into the temples 14,16 of the eyeglasses, providing a sleek and stylish design. In embodiments where the electronic eyeglass set includes one or more bone conducting transducers 18, one or more of the remaining electronic components may be arranged in the connected section 13 due to the limited space in the pliable section 17 and / or the tip section 15. For example, one or more microcontrollers 20, wireless communication interfaces 22, batteries 24, user interfaces, interfaces for control of a device delivering the audio signal to the bone conduction transducer 18, or the like, may be arranged in the connected section 13. The electronic components arranged in the connected section 13 may preferably be connected to the first printed circuit board 26, i.e. the printed circuit board arranged in the connected section 13.

[0074] In some embodiments, the electronic eyeglass set comprises an antenna driving circuit. The antenna driving circuit is designed to drive the elongated metal element 40 extending along a portion of the first and / or second temple 14,16 to function as an antenna. The antenna driving circuit is thus configured to transmit and receive signals using the elongated metal element 40 as the antenna. The antenna driving circuit may be connected to the first and / or second printed circuit board 19,26. The antenna driving circuit may comprise a short-range communication chip. This chip may be a Bluetooth chip, an NFC chip, or any other type of short-range communication chip enabling wireless communication between the electronic eyeglass set and other devices. The short-range communication chip may be connected to the first and / or second printed circuit board 19,26.

[0075] The elongated element 40 may form any suitable antenna type including a mono- pole antenna, a helix antenna, a whip, or a loop antenna. The electronic eyeglass set may comprise a pair of elongated metal elements 40 which together form a dipole antenna.

[0076] The elongated metal element 40 may have a length corresponding to an antenna frequency in the range of 1 GHz to 10GHz, optionally 2 GHz to 6 GHz, optionally around 2.4 GHz or 5 GHz. For instance, the length of the metal element may for some implementations be in the range of 10 cm - 1 cm, optionally 7 cm - 1.5 cm, optionally about 4 cm -1 ,5 cm. In some specific applications the length of the metal element is about 3 cm. However, the length may vary depending on the specific antenna implementation.

[0077] The electronic eyeglass set may comprise one or more visual indication means. It will be appreciated that, although the visual indication means is described in relation to the eyeglass set in Figs. 1-3, embodiments also include other electronic eyeglass sets with a visual indication means. For example, embodiments include electronic eyeglass sets with a visual indication means but with only one of the first and second printed circuit boards 19,26, and / or electronic eyeglass sets with a visual indication means which does not comprise an elongated metal element 40. The visual indication means may be a light source arranged on the electronic eyeglass set. The light source is designed to emit light to provide visual information to the user of the electronic eyeglass set. Thus, the functionality of the eyeglasses may be enhanced by incorporating visual cues.

[0078] The light source is preferably located on an inner side of the first and / or second temple 14,16. The inner side may be defined as a side of the respective temple

[0079] 14,16 closest to the middle section 10, and / or as a side of the respective temple

[0080] 14,16 that faces the other temple 14,16 when the temples 14,16 are arranged to extend substantially perpendicular to the middle section 10.

[0081] The light source may be located in the connected section 13. Additionally, or alternatively, the light source may be located closer to a connected end of the temple

[0082] 14,16 (i.e. an end of the temple 14,16 connected to the middle section 10) than a tip end of the temple 14,16 (i.e. an end near the tip section 15; an opposite end to the connected end). For example, the light source may be located within 4 centimeters, optionally 3 centimeters, optionally 2 centimeters, optionally 1 centimeter, from the connected end of the temple 14,16.

[0083] In embodiments, there may be provided at least one light source on the first temple 14 and at least one light source on the second temple 16. The light sources may thus be used to provide symmetrical visual cues to the user. Furthermore, the light sources on both temples 14,16 may be used to indicate a direction (e.g. left or right) to the user by selectively activating the respective light source. This may be particularly advantageous when, for example, the electronic eyeglass set is used together with a GPS system to provide directions to a specific location or the like.

[0084] The electronic eyeglass set may comprise a plurality of light sources arranged along the inner side of the first and / or second temple 14,16. That is, a plurality of light sources may be spaced apart along the inner side of the first and / or second temple 14,16.

[0085] The light source may be at least partially embedded in the first temple 14. For example, the light source may be embedded or incorporated into a design element of the eyeglasses, such as a logo or emblem, to provide a visually appealing feature.

[0086] The light source can be a variety of light-emitting devices such as a light emitting diode (LED), an organic light-emitting diode (oled), a light-emitting polymer (lep), a laser diode, a quantum dot light-emitting diode (qled), a micro led (pled), an electroluminescent display, an incandescent bulb, a fiber optic light source, a liquid crystal display (led) backlight, or an electroluminescent wire.

[0087] The light source is configured to be used for applications such as displaying notifications, indicating status (e.g. battery status) or mode changes, or providing visual feedback. The light source may be connected to the first printed circuit board 26 and / or the second printed circuit board 19 for power and control.

[0088] The electronic eyeglass set may comprise a light control circuit configured to control the light source. The light control circuit may control the light source by sending one or more control signals to the light source. The control signals may include control signals for controlling activation, deactivation, intensity, and / or colour of the light source. The light control circuit may be connected to, or comprised by, the first and / or second printed circuit board 19,26.

[0089] The first and second temples may be made from a plastic, such as polyamide, nylon, or polycarbonate, a fibre-based material such as carbon fibre or cellulose acetate, carbon, or any other suitable material.

[0090] According to some embodiments the first and second temples 14,16 are made from cellulose acetate. Fig. 4 shows a method of manufacturing an electronic eyeglass set with temples 14,16 made from cellulose acetate.

[0091] In step 401 , a middle section 10 is provided. The middle section 10 may be a middle section as previously described in relation to Figs. 1-3.

[0092] In step 403, there is provided a first temple 14 and a second temple 16 made from cellulose acetate.

[0093] In step 405, a cavity is created in at least one of the first temple 14 and the second temple 16. The cavity is configured to accommodate one or more electronic components such as the first printed circuit board 26, the second printed circuit board 19, and / or the elongated metal element 40. The creation of the cavity involves removing a portion of the material of the temple 14,16 to create a space for the placement of the one or more electronic components. The size, shape, and location of the cavity can be determined based on the size and shape of the electronic components to be arranged therein, such as the first printed circuit board 26, the second printed circuit board 19, the elongated metal element 40, and / or one or more other electronic components, as well as the desired arrangement of these components within the temple.

[0094] The cavity may be created using a variety of techniques. One such technique is milling, which involves using a cutting tool to remove material from the first temple 14 to create the cavity. This technique allows for precise and accurate creation of the cavity according to design specifications. Other techniques for creating the cavity can include laser cutting, CNC machining, or subtractive manufacturing methods such as waterjet cutting or plasma cutting.

[0095] In step 407, one or more electronic components are arranged in the cavity. These electronic components may include the first printed circuit board 26, the second printed circuit board 19, the elongated metal element 40, and / or one or more other electronic components such as the bone conducting transducer 18. The electronic components may further be secured in the cavity using an adhesive or any other suitable means.

[0096] After arranging the electronic components in the cavity, the cavity may be filled with a filler material to further secure the electronic components in place. The filler material may be a silicone gel, cellulose acetate, a thermoplastic elastomer, a polyurethane-based material, a rubber compound, a gel-like material, a resilient material, or a resin or adhesive, or any other suitable filler material. Alternatively, or additionally, the cavity may be sealed by a lid which may be fastened using an adhesive or any other suitable means.

[0097] In step 409, the electronic eyeglass set is assembled by attaching the first temple 14 and the second temple 16 to the middle section 10.

[0098] It will be appreciated that the method steps need not be performed in the illustrated order. For example, the temples 14,16 may be attached to the middle section in step 409 before the cavity is created in step 405 and / or before the electronic components are arranged in the cavity in step 407.

[0099] The cavity in any one of the temples 14, 16 may be formed to closely match the shape of each of the printed circuit boards 19, 26 so that the printed circuit board is in contact with opposing walls of the cavity adding to the structural support of the temple 14, 16. Each of the printed circuit boards may be formed as at least one plane for carrying the wiring between components and connections to the components. The surface of one plane of the printed circuit board is arranged facing the inner side of the temple.

[0100] The first and / or second temples 14,16 may be made from a fibre-based material (e.g. carbon fibre, and / or acetate such as bio acetate and / or cellulose acetate), metal (e.g. gold, silver, titanium, steel (such as stainless steel), iron, monel, beryllium, copper, or any combination thereof (for example an alloy of copper and beryllium), wood, horn (such as buffalo horn), plastic (e.g. Grimalid TR90, vinyl, polyetherimide, nylon, polyamide, polycarbonate), composite materials, or any other suitable material.

[0101] The middle section 10 may be made from the same material as the first and / or second temple(s) 14,16. Alternatively, the middle section 10 may be made from a different material than the first and / or second temple 14,16. For example, the middle section 10 may be made from one or more of the above-mentioned materials, while the first and / or second temples 14,16 are made from one or more other materials of the above-mentioned materials. For instance, the middle section 10 may be made from a metal, while the first and / or second temples 14,16 are made from a fibrebased material (such as acetate or cellulose acetate) or a plastic material, or vice versa. As described in relation to Fig. 4, and in particular in step 405, the cavity may be formed in the first and / or second temple 14,16 by a subtractive manufacturing method. That is, a method where material is removed from the temple 14,16 so as to obtain the cavity. The subtractive method may include milling, laser cutting, CNC machining, or other subtractive manufacturing methods such as waterjet cutting or plasma cutting.

[0102] A subtractive manufacturing method is particularly advantageous because it allows the cavity to be created in a temple 14,16 already having substantially a temple shape. Here, temple shape refers to the final shape of a temple 14,16 when the eyeglasses are worn by a user. In other words, temple shape refers to a temple 14,16 having a shape conforming to the side of the user’s head so as to allow the temple 14,16 to rest on the ear of the user. The temple shape thus typically comprises a curved portion configured to curve around the ear of the user. The curved portion may, for example, be at least partly formed by the pliable section 17.

[0103] In other words, the cavity may be created in a temple 14,16 having substantially a temple shape and / or a shape including a curved portion for curving around the ear of the user.

[0104] That is, the temple 14,16 may in a first step be formed and / or shaped so as to form substantially a temple shape. The first step may comprise forming a curved portion in the temple 14,16. Such forming may include bending the pliable section 17 so as to form the curved portion. Such forming may alternatively be formed without any substantial bending, e.g. by cutting a temple 14,16 with temple shape from a block of material.

[0105] In a second, and subsequent step, the cavity may be formed, e.g. by a subtractive manufacturing method.

[0106] By creating the cavity in a temple 14,16 having a temple shape, it may be ensured that the cavity has the appropriate size and shape, and further that the size and shape of the cavity is not distorted during bending of the pliable section 17. Hence, unnecessary bending of the cavity, and of the electronics arranged in the cavity, may be avoided or at least reduced.

[0107] This is particularly advantageous when the cavity is at least partly formed in the curved portion of the temple 14,16 (which may correspond to the pliable section 17). In other words, the second step may include forming a cavity in the curved portion of a temple 14,16 having a temple shape.

[0108] As described in relation to step 407, the cavity may be filled with a filler material after the electronic component(s) have been arranged therein. Examples of filler materials include a silicone gel, cellulose acetate, a material comprising a mixture of acetate and acetone, a thermoplastic elastomer, a polyurethane-based material, a rubber compound, a gel-like material, a resilient material, or a resin or adhesive, or any other suitable filler material.

[0109] When filling the cavity with the filler material, the filler material may adopt a shape that conforms to at least one of the electronic components arranged in the cavity. In other words, the filler material may be formable and / or malleable when filling the cavity. For example, the filler material may, when filling the cavity, be sufficiently soft or pliable to allow it to conform to the electronic component(s) arranged in the cavity. As another example, the filler material may be molten or liquid to allow the filler material to at least partly flow into the cavity so as to conform to the electronics arranged therein. As yet another example, the filler material may be a 3D printable material that can be deposited (in situ) in the cavity by any known 3D printing technique. Such 3D printing techniques typically include heating (e.g. softening and / or melting) the filler material and depositing the heated filler material in the cavity.

[0110] The filler material may accordingly be in contact with at least one of the electronic components arranged in the cavity. The at least one electronic component may accordingly be secured in its place within the cavity by the filler material.

[0111] After the cavity has been filled with the filler material, the filler material may undergo a setting process in which the filler material is caused or allowed to set, cure and / or harden. For example, the filler material may be allowed to cool down so as to solidify. As another example, a filler material in the form of a resin or the like may be allowed to cure. In other words, embodiments may comprise a step of filling the cavity with a filler material, and a subsequent step of allowing the filler material to set, cure and / or harden.

[0112] In some embodiments at least one of the printed circuit boards is a rigid printed circuit board and, in some embodiments, at least one of the printed circuit boards is a flexible printed circuit board including a flexible substrate. The printed circuit boards of the electronic eye glass may according to some embodiments all be rigid printed circuit boards, according to some embodiments all be flexible printed circuit boards, or according to some embodiments include both rigid and flexible printed circuits boards.
