Description

Technical Field

[0001] This utility model relates to the field of wearable device technology, specifically to an audio glasses. Background Technology

[0002] Audio glasses are glasses with speakers mounted on the temples. Wearing these glasses allows users to listen to music, make voice calls, and perform other functions directly through these speakers. Audio glasses typically hide the speakers within the temples, playing sound through sound holes. However, the distance between these sound holes and the user's ear canal is generally relatively far, resulting in a higher sound volume and potentially compromising user privacy.

[0003] Currently, there are also solutions to reduce the distance between the sound outlet and the user's ear canal. For example, the technical solution disclosed in patent publication number CN216905270U has the inner side of the temple facing the user's head and the outer side of the temple facing away from the user's head. The speaker is placed in the temple. A screw cap with an arc-shaped baffle is set on the outer side of the shell. A front sound outlet is set on the switching handle on the side of the screw cap. The screw cap rotates along the axis in the inward and outward directions. When the switching handle is moved forward to the designated position, the arc-shaped baffle is adjusted to the outer wall of the speaker support without blocking the clearance notch. At this time, the sound emitted by the speaker is transmitted outward through the clearance notch and the main sound outlet in sequence. When the switching handle is moved backward to the designated position, the arc-shaped baffle is used to cover the clearance notch. At this time, the sound emitted by the speaker is transmitted outward through the sound guide notch and the front sound outlet in sequence. The user can switch the sound outlet channel by moving the switching handle.

[0004] However, in the existing design, the rotation axis is along the inward and outward direction. To facilitate user operation, the switching handle is moved forward to the storage state. The front sound hole on the switching handle faces the front of the temple. When rotating the switching handle, it is easy for the switching handle to rub against the user's face. Moreover, if it is to be rotated to a position close to the user's ear, due to the special structure of the ear, the ear structure will partially obstruct the rotation. During the rotation, the ear will be squeezed or bumped, resulting in a poor user experience. Summary of the Invention

[0005] The purpose of this utility model is to provide an audio glasses, including temples, with the side facing the user's head as the inner side and the side facing away from the user's head as the outer side, and the end connected to the lens frame as the front end; a first mounting structure fixed to the lower side of the temples; a second mounting structure rotatably disposed relative to the first mounting structure, the second mounting structure having a sound outlet channel; a speaker installed in a sound cavity and fixed to the first or second mounting structure, the sound cavity being surrounded by the second mounting structure and / or the first mounting structure; the second mounting structure can be flipped upwards around an axis perpendicular to the inner and outer directions to a folded storage state, and can be flipped downwards around the axis to an unfolded state; when the second mounting structure is in the folded storage state, the second mounting structure is at least partially folded and stored on the outer side of the temples, the sound cavity is connected to the outside through a sound outlet hole penetrating the cavity wall, and the audio glasses emit sound through the sound outlet hole; when the second mounting structure is in the unfolded state, the second mounting structure extends below the temples, the sound cavity is connected to the outside through the sound outlet channel, and the audio glasses emit sound through the sound outlet channel.

[0006] As can be seen from the above, the audio glasses provided by this utility model have a second mounting structure that can be flipped upwards around an axis perpendicular to the inside and outside direction to a folded storage state, and can be flipped downwards around the axis to an unfolded state. When the second mounting structure is in the folded storage state, the sound cavity is connected to the outside through a sound outlet hole penetrating the cavity wall, and the audio glasses emit sound through the sound outlet hole. When the second mounting structure is in the unfolded state, the sound cavity is connected to the outside through a sound outlet channel, and the audio glasses emit sound through the sound outlet channel. The audio glasses of this utility model can switch the sound outlet mode of the sound cavity by flipping the second structure up and down.

[0007] The second mounting structure of this utility model switches between the folded and unfolded states by flipping up and down. This allows the second mounting structure to be flipped close enough to (or even pressed against) the user's ear when the user is using the sound output channel, without worrying about the second mounting structure rubbing against the user's face during the flipping process, thus improving the user experience.

[0008] In one possible implementation, the second mounting structure has a base rotatably connected to the first mounting structure and an extension fixed to the base; a sound outlet channel is formed in the extension, and the sound outlet position of the sound outlet channel is located at the end of the extension away from the base; when the second mounting structure is in the unfolded state, the extension extends from the base toward the user's ear.

[0009] In one possible implementation, the base is located in front of the user's ear and is tilted relative to the front-back direction.

[0010] As can be seen from the above, this design allows the second mounting structure to be flipped upwards to the outside of the temple and downwards to the user's ear, while ensuring that the flipping process of the second mounting structure avoids the user's ear, thus improving the user experience.

[0011] Furthermore, the extension extends along a curved or zigzag path so that when the second mounting structure is in the folded storage state, the extension is stored on the outside of the temple.

[0012] As can be seen from the above, the extension portion of this utility model extends along a curved or broken path. When the second mounting structure is in the unfolded state, the sound outlet position of the sound outlet channel is close to the ear canal of the user's ear, which helps to make the appearance structure of the glasses simple when the second mounting structure is in the folded storage state.

[0013] In one possible implementation, the base is connected to the first mounting structure via a threaded member, the centerline of which coincides with the axis; the threaded member includes a head and a rod; the rod passes through the first mounting structure and is threadedly connected to the base, and the first mounting structure is pressed between the base and the head; or, the rod passes through the base and is threadedly connected to the first mounting structure, and the base is pressed between the first mounting structure and the head.

[0014] As can be seen from the above, this gives the first mounting structure a damping force when it engages with the base, which helps to improve the user's feel when flipping the second mounting structure. Furthermore, by adjusting the tightness of the threaded connection, the magnitude of the damping force can also be adjusted, which helps to further meet the user's needs for the magnitude of the damping force (for example, by adjusting the magnitude of the damping force, the second mounting structure can be kept in any position during the flipping process).

[0015] In one possible implementation, the first mounting structure has a first conical surface and a base having a second conical surface adapted to the first conical surface, the centerlines of the first conical surface and the second conical surface coincide, and the first conical surface and the second conical surface abut against each other under the action of the threaded part.

[0016] As can be seen from the above, the rotational fit between the base and the first mounting structure is achieved by using two coaxial, mutually compatible conical surfaces that face each other and make surface contact. This avoids shaking between the base and the first mounting structure during the flipping process and the structure is simple.

[0017] In one possible implementation, a first limiting structure is provided between the first mounting structure and the second mounting structure, and / or, a first limiting structure is provided between the temple and the second mounting structure; the first limiting structure is used to keep the second mounting structure on the outside of the temple when the second mounting structure is in a folded storage state.

[0018] As can be seen from the above, when the second mounting structure is in the folded storage state, the present invention keeps the second mounting structure on the outside of the temple, preventing the second mounting structure from shaking under the action of gravity or user movement (or even automatically flipping down and unfolding), thereby improving the user experience.

[0019] In one possible implementation, a second limiting structure is provided between the second mounting structure and the first mounting structure. The second limiting structure is used to hold the second mounting structure at a specified angle when the second mounting structure is in the unfolded state.

[0020] As can be seen from the above, this utility model uses a second limiting structure to maintain the position of the second mounting structure, which can prevent the second mounting structure from shaking during the use of the audio glasses, thereby improving the user experience.

[0021] In one possible implementation, the first mounting structure has a first limiting part and a second limiting part, and the second mounting structure has a third limiting part. The first limiting part and the third limiting part form a first limiting structure, and the second limiting part and the third limiting part form a second limiting structure. When the second mounting structure is in a folded storage state, the first limiting part and the third limiting part interact with each other. When the second mounting structure is in an unfolded state, the second limiting part and the third limiting part interact with each other.

[0022] As can be seen from the above, this utility model only needs to set a third limiting part on the second mounting structure, which works in conjunction with the first limiting part and the second limiting part on the first mounting structure to maintain the position of the second mounting structure in both the unfolded and folded storage states. This is beneficial for simplifying the structure, especially for audio glasses which are small in size and have relatively delicate and small structures, requiring a simple structural design. Moreover, while meeting the limiting requirements, reducing the number of structural components helps to reduce the pressure on the ears during wearing and improve the user's wearing experience.

[0023] In one possible implementation, the second mounting structure has a first surface at the end away from the sound cavity, and the sound outlet channel opens onto the first surface; when the second mounting structure is in the unfolded state, the first surface faces inward and gradually tilts outward from front to back.

[0024] As can be seen from the above, since the sound outlet is opened on the first side facing inward, it is beneficial to improve the privacy of sound playback; and since the first side gradually tilts outward from front to back, it is beneficial to make the first side better match the user's ear structure when the second mounting structure is in the unfolded state, so that the sound outlet position of the sound outlet is better facing the user's ear canal, and the sound outlet is directed towards the user's ear canal, thus improving the user experience.

[0025] In one possible implementation, the first mounting structure can be adjusted in position relative to the temple in the front-back direction.

[0026] As can be seen from the above, this design allows the audio glasses of this invention to adapt to the wearing and usage needs of different users. For example, when the second mounting structure is in a folded and stored state, the front-to-back position of the first mounting structure relative to the temples can be adjusted according to the user's desired amplification level of the sound outlet, so that the sound outlet is closer to or further away from the ear. When the second mounting structure is in an unfolded state, the front-to-back position of the sound outlet opening relative to the ear canal can also be adjusted according to the position of the sound outlet opening in the second mounting structure relative to the ear, so that the sound outlet opening is closer to the ear canal. Users can make adjustments according to their individual needs, which helps to improve the adaptability and operational flexibility of the audio glasses, thereby enhancing the user's wearing experience.

Detailed Implementation

[0028] For the sake of simplicity, this embodiment Figures 1 to 7 A unified spatial rectangular coordinate system (right-handed system) is used to represent the relative positional relationships between features. The X-axis represents the front-back direction, the Z-axis represents the up-down direction, and the Y-axis represents the inside-out direction.

[0029] Please see Figures 1 to 7This embodiment provides audio glasses, including: temples 11, a lens frame 12 fixed to the negative X-axis end (i.e., front end) of temples 11, a first mounting structure 13 fixed to the negative Z-axis side (i.e., lower side) of temples 11, and a second mounting structure 14 rotatably disposed relative to the first mounting structure 13. The side of temples 11 facing the user's head during use is the inner side, and the side facing away from the user's head is the outer side.

[0030] In this embodiment, the first mounting structure 13 has a cylindrical body 131 and a first wall 132 and a second wall 133 fixed to both ends of the cylindrical body 131 along the axial direction. The center line of the cylindrical body 131 coincides with the rotation axis of the second mounting structure 14. The first wall 132 is located at the front end of the cylindrical body 131 along the axial direction. The cylindrical body 131, the first wall 132 and the second wall 133 form a sound cavity 16. The loudspeaker 15 is installed in the sound cavity 16 and fixed to the inner wall of the cylindrical body 131. The cylindrical body 131 has a sound outlet hole 134 that penetrates the cavity wall on the negative Z-axis side.

[0031] The second mounting structure 14 has a base 141 rotatably connected to the first mounting structure 13 and an extension 142 fixed to the base 141. The extension 142 extends along a curved path, and a sound outlet channel 143 is formed in the extension 142. The extension 142 has a first surface 1421 at the end away from the base, and the sound outlet position 1431 of the sound outlet channel 143 at the end away from the base 141 opens into the first surface 1421.

[0032] The base 141 is connected to the first mounting structure 13 via a threaded member 17. The centerline of the threaded member 17 coincides with the axis. The base 141 includes an arc-shaped wall 1411 and a third wall 1412 that are fixedly connected. The third wall 1412 has a second conical surface, and the first wall 1412 has a first conical surface. The first and second conical surfaces have the same taper and are mutually compatible. The centerlines of the first and second conical surfaces coincide. Under the action of the threaded member 17, the first and second conical surfaces abut against each other to achieve rotational limitation of the second mounting structure 14 relative to the first mounting structure 13.

[0033] After the user wears the audio glasses, the base 141 is located in front of the user's ear. The second mounting structure 14 can be flipped upward around an axis perpendicular to the Y-axis (i.e., perpendicular to the inside and outside direction) to a folded storage state, and can be flipped downward around the axis to an unfolded state. The axis of rotation of the second mounting structure 14 is inclined relative to the X-axis direction. When the second mounting structure 14 is in the folded storage state, the extension 142 is stored on the outside of the temple 11, the opening of the sound channel 143 facing the base 141 is blocked by the cylindrical body 131, and the sound cavity 16 is connected to the outside through the sound hole 134 penetrating the cavity wall. The audio glasses emit sound through the sound hole 134, that is, emit sound in an external manner. When the second mounting structure 14 is in the unfolded state, the second mounting structure extends below the temple, the extension 142 extends from the base 141 toward the user's ear, the sound hole 134 is connected to the sound channel 143, and the sound cavity 16 is connected to the outside through the sound channel 143. The first surface 1421 faces inward and gradually tilts outward from front to back. The audio glasses emit sound through the sound outlet position 1431 on the first surface 1421.

[0034] In this embodiment, the first wall 132 has a recessed groove 1321 at the axial position, extending from front to back. The first mounting structure 13 includes a nut 136, which is fixed in the groove 1321 of the first wall 132. The inner wall of the nut 136 has threads. The threaded part 17 includes a head 171 and a rod 172. The rod 172 passes through the third wall 1412 and is connected to the thread on the nut 1321. The base 141 is pressed between the first wall 132 and the head 171. This makes the engagement between the first mounting structure 13 and the base 141 damped, which helps to improve the user's feel when flipping the second mounting structure. By rotating the threaded part 17 along its centerline, the tightness of the threaded part 17 connection can be adjusted, thereby adjusting the pressure between the third wall 1412 and the first wall 132. This allows for adjustment of the damping force on the rotation of the second mounting structure 14 relative to the first mounting structure 13, which helps to further meet the user's requirements for the magnitude of the damping force (for example, by adjusting the magnitude of the damping force, the second mounting structure can be kept in any position during the flipping process).

[0035] In this embodiment, an arc-shaped limiting groove 135 is provided on the first wall 132, and a limiting protrusion 144 (an example of a third limiting part) is provided on the third wall 1412. The limiting protrusion 144 is accommodated in the arc-shaped limiting groove 135 and can slide along it. The arc-shaped limiting groove 135 has a first end region 1351 (an example of a first limiting part), a second end region (an example of a second limiting part) distributed along its arc length direction, and an intermediate region 1352 located between the first end region 1351 and the second end region. The groove depth of the first end region 1351 is greater than the groove depth of the intermediate region 1352, and the groove depth of the second end region is greater than the groove depth of the intermediate region 1352.

[0036] In this embodiment, the first end region 1351 and the limiting protrusion 144 form a first limiting structure. When the second mounting structure 14 is in the folded storage state, the walls of the first end region 1351 and the limiting protrusion 144 abut against each other, holding the second mounting structure 14 on the outside of the temple. The second end region and the limiting protrusion 144 form a second limiting structure. When the second mounting structure 14 is in the unfolded state, the walls of the second end region and the limiting protrusion 144 abut against each other, holding the second mounting structure 14 at a specified angle. This embodiment provides a first limiting structure between the first and second mounting structures, which helps to prevent the second mounting structure from shaking under the action of gravity or user movement (or even automatically flipping down and unfolding). By providing a second limiting structure, it is beneficial to prevent the second mounting structure from shaking when the audio glasses are in a shaking state, thereby improving the user experience.

[0037] It should be noted that the second mounting structure 14 is held at a specified angle. This specified angle is a preset angle at which the second mounting structure 14 can be unfolded when it is folded and stored by the user. Multiple specified angles can be set to meet different flipping angle requirements of the user.

[0038] In this embodiment, the first mounting structure 13 has a cylindrical body 131 and a first wall 132 and a second wall 133 fixed to both axial ends of the cylindrical body 131, wherein the cylindrical body 131, the first wall 132, and the second wall 133 form a sound cavity 16. Alternatively, in other embodiments of this invention, the sound cavity may be formed by both the first and second mounting structures, or by the second mounting structure alone. For example, the first mounting structure has a cylindrical body, and the base of the second mounting structure has a third wall and a fourth wall fixed to both axial ends of the cylindrical body, together forming the sound cavity. Another example is that the first mounting structure has a bracket, and the base of the second mounting structure forms the sound cavity, with the base of the second mounting structure rotatably connected to the bracket. In this case, the bracket may be located outside the cavity at the base or inside the cavity at the base. When the sound cavity is enclosed by the first mounting structure and the second mounting structure, the loudspeaker can be fixed to either the first mounting structure or the second mounting structure; when the sound cavity is enclosed by the second mounting structure, the loudspeaker is fixed to the second mounting structure.

[0039] In this embodiment, a sound outlet 134 penetrating the cavity wall is provided on the negative side of the cylindrical body 131 facing the Z-axis. Alternatively, in other embodiments of this utility model, a sound outlet penetrating the cavity wall can also be provided on the second wall of the first mounting structure; and when the sound cavity is surrounded by the second mounting structure, a sound outlet needs to be provided on the second mounting structure.

[0040] In this embodiment, when the second mounting structure 14 is in the folded and stored state, the cylindrical body 131 blocks the opening of the sound outlet channel 143 facing the base 141, thereby preventing sound from emanating from the opening of the sound outlet channel 143 away from the base 141. Alternatively, in other embodiments of this invention, a sealing member can be provided on the temple, which blocks the opening of the sound outlet channel away from the base when the second mounting structure is in the folded and stored state, thus isolating the sound outlet channel from the outside. Preferably, the first mounting structure is used to open or close the sound cavity through the sound outlet channel to connect with the outside, which simplifies the structure of the audio glasses.

[0041] In this embodiment, the base is located in front of the user's ear, and the axis of rotation of the second mounting structure 14 is inclined relative to the X-axis direction (i.e., the front-to-back direction). Optionally, in other embodiments of this utility model, the axis of rotation of the second mounting structure can also be parallel to the X-axis direction. Preferably, the axis of rotation of the second mounting structure is inclined relative to the X-axis direction. This facilitates the second mounting structure to flip upwards to the outside of the temple and downwards to the user's ear, while avoiding the user's ear during the flipping process, thus improving the user experience. The angle of inclination of the axis relative to the X-axis direction can be 10°, 15°, 30°, 50°, etc. The larger the angle of inclination of the axis relative to the X-axis direction, the better the effect of the second mounting structure avoiding the user's ear during the flipping process. However, if the angle is too large, when the second mounting structure is in the folded storage state, it is difficult for the extension to be fully stored on the outside of the temple, resulting in a decrease in aesthetics. Preferably, the angle of inclination of the axis relative to the X-axis direction is set between 10° and 30°. This is beneficial to balance the effect of the second mounting structure avoiding the user's ear during the flipping process with the storage of the extension on the outside of the temple, improving the aesthetics.

[0042] In this embodiment, the extension 142 extends along a curved path. Alternatively, in other embodiments of this invention, the extension may also extend along a broken line path; the extension may also extend along a straight line. Preferably, the extension extends along a curved or broken line path. When the second mounting structure is in the unfolded state, the sound outlet position of the sound outlet channel is close to the ear canal of the user's ear, which helps to make the appearance of the glasses simple when the second mounting structure is in the folded storage state.

[0043] In this embodiment, the first wall 132 has a first conical surface, and the third wall 1412 has a second conical surface adapted to the first conical surface. The centerlines of the first and second conical surfaces coincide, and the first and second conical surfaces abut against each other under the action of the threaded component 17. Alternatively, in other embodiments of this invention, the surfaces abutting against each other under the action of the threaded component can also be planes. A limiting structure can be provided between the first mounting structure and the base to prevent wobbling when the second mounting structure is flipped. For example, the rotation path can be limited by the cooperation of a guide rail and a slider.

[0044] In this embodiment, the rod 172 passes through the base 141 and is threadedly connected to the first mounting structure 13, with the base 141 pressed between the first mounting structure 13 and the head 171. Alternatively, in other embodiments of this utility model, the rod may pass through the first mounting structure and be threadedly connected to the base, with the first mounting structure pressed between the base and the head. For example, the first mounting structure has a bracket, the base of the second mounting structure forms a sound cavity, the bracket is located outside the cavity of the base, the rod passes through the bracket on the first mounting structure and is threadedly connected to the base, and the first mounting structure is pressed between the base and the head, thus achieving a rotatable connection between the base of the second mounting structure and the bracket.

[0045] In this embodiment, the first mounting structure 13 includes a nut 136; alternatively, in other embodiments of this utility model, threads can be directly formed on the first mounting structure, for example, a groove is provided on the first wall that is recessed from front to back, the groove is threaded, and the shank of the threaded part passes through the third wall and is connected to the thread on the first wall.

[0046] In this embodiment, the base 141 is connected to the first mounting structure 13 via a threaded member 17. The centerline of the threaded member 17 coincides with the axis. Optionally, in other embodiments of this invention, the threaded member may not be provided. For example, a rotating shaft may extend from one of the third wall and the first wall, with the other fixed to the rotating shaft, to achieve the connection. Optionally, the centerline of the threaded member may not coincide with the axis. For example, based on the rotating shaft extending from one of the third wall and the first wall, with the other fixed to the rotating shaft, the centerline of the threaded member may be set at a position off-axis (such as above the axis), thereby achieving the connection between the base and the first mounting structure and the setting of the damping force between them. Preferably, the base and the first mounting structure are connected via a threaded member, and the centerline of the threaded member coincides with the axis. On the one hand, the threaded member simultaneously achieves the installation and fixation of both and provides damping force, which is beneficial for simplifying the structure. On the other hand, the coincidence of the centerline of the threaded member with the axis ensures a more balanced force between the base and the first mounting structure, which helps to avoid uneven force distribution.

[0047] In this embodiment, by adjusting the tightness of the threaded connection 17, the pressure between the third wall 1412 and the first wall 132 can be adjusted, thereby adjusting the damping force of the second mounting structure 14 relative to the first mounting structure 13. Alternatively, in other embodiments of this invention, the threaded connection may only serve a fixing function, and the pressure between the third wall and the first wall may be fixed. Preferably, the ability to adjust the damping force of the second mounting structure relative to the first mounting structure is preferred, as this helps to further meet the user's requirements for the magnitude of the damping force.

[0048] In this embodiment, the sound outlet channel 143 opens onto the first inward-facing surface 1421. Alternatively, in other embodiments of this invention, the sound outlet channel may also open onto the end of the extension away from the sound cavity, with the opening facing rearward. Preferably, the sound outlet channel opens onto the first inward-facing surface, which is beneficial for improving the privacy of sound playback.

[0049] In this embodiment, the second mounting structure 14 has a first surface 1421 at the end away from the sound cavity 16. When the second mounting structure 14 is in the unfolded state, the first surface 1421 faces inward and gradually tilts outward from front to back. Optionally, in other embodiments of this utility model, the first surface may not be tilted. Preferably, the first surface gradually tilts outward from front to back, which helps to better match the user's ear structure when the second mounting structure is in the unfolded state. Furthermore, with the sound outlet opening on the inward-facing first surface, the sound outlet position of the sound outlet can be better oriented towards the user's ear canal, thus improving the user experience.

[0050] In this embodiment, the audio glasses have a first limiting structure and a second limiting structure, both of which are located between the first wall 132 and the third wall 1412. Optionally, in other embodiments of this invention, only the first limiting structure or only the second limiting structure may be provided. The first limiting structure may also be located between the arc-shaped wall and the cylindrical body, or between the temple and the second mounting structure. The second limiting structure may also be located between the arc-shaped wall and the cylindrical body. If there are other cooperating walls between the base of the second mounting structure and the first mounting structure, the second limiting structure may also be located between these other cooperating walls.

[0051] In this embodiment, the first end region 1351 and the limiting protrusion 144 form a first limiting structure, and the second end region and the limiting protrusion 144 form a second limiting structure. Alternatively, in other embodiments of this utility model, the first limiting structure and the second limiting structure may be formed by other components, such as the first limiting structure or the second limiting structure being formed by two interacting magnets, or the first limiting structure or the second limiting structure being formed by two mutually cooperating limiting protrusions, etc.

[0052] In this embodiment, the first end region 1351 and the limiting protrusion 144 form a first limiting structure, and the second end region and the limiting protrusion 144 form a second limiting structure. Alternatively, in other embodiments of this utility model, the first mounting structure may have a first limiting part, the second mounting structure may have a third limiting part and a fourth limiting part, the first limiting part and the third limiting part form the first limiting structure, and the first limiting part and the fourth limiting part form the second limiting structure. Alternatively, the first mounting structure may have a first limiting part and a second limiting part, the second mounting structure may have a third limiting part and a fourth limiting part, the first limiting part and the third limiting part form the first limiting structure, and the second limiting part and the fourth limiting part form the second limiting structure.

[0053] In this embodiment, the first mounting structure is fixed to the temple. Optionally, in other embodiments of this invention, the first mounting structure can also be adjusted relative to the temple in the front-to-back direction. For example, a guide rail can be provided between the temple and the first mounting structure to allow the first mounting structure to slide. This structural design, where the first mounting structure can be adjusted relative to the temple in the front-to-back direction, allows users to adjust the position of the first mounting structure according to their wearing comfort. This helps the audio glasses adapt to the wearing and usage needs of different users.

[0054] Finally, it should be emphasized that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications.
