Technical Field

[0001] The present invention relates to the technical field of intelligent wearable devices, and in particular to bone conduction hearing-aid glasses. Background Art

[0002] Glasses, consisting of lenses and frames, serve both as eye protection and a cosmetic accessory. Bone conduction hearing aid glasses, a type of eyewear, not only provide vision correction but also convert external sounds into mechanical vibrations of varying frequencies, transmitting them through the skull, bony labyrinth, and auditory center. Compared to traditional diaphragm sound transmission, bone conduction eliminates the need for sound waves to diffuse through the air, enabling clear sound reproduction in noisy environments while minimizing distraction.

[0003] However, existing bone conduction hearing aid glasses still have shortcomings in terms of fit. The hearing aid module requires close contact with the user's head to effectively transmit sound, but current frame designs make it difficult to maintain a tight fit, affecting sound transmission and making the user experience less comfortable. Furthermore, the single hearing aid module's prolonged contact with the head can easily cause skin injuries at the site of compression, reducing user comfort.

[0004] Therefore, a new bone conduction hearing aid glasses is urgently needed to solve the above technical problems. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the hearing aid module of existing bone conduction hearing aid glasses needs to be in close contact with the user's head to effectively conduct sound, but the current frame design is difficult to ensure continuous and close fit, which affects the sound transmission effect and the comfort experience is poor.

The screw is rotatably connected to the inside of the support arm, and the support plate is threadedly connected to the screw. The bottom end of the support plate passes through the support arm and is fixedly connected to the first hearing aid. The driving gear is fixed to the screw on one side of the support plate, and the bottom end of the driving gear extends to the outside of the support arm. When driven by an external force, the driving gear can drive the screw so that the support plate drives the first hearing aid to move linearly in a direction perpendicular to the support arm.

[0009] In a specific embodiment of the above-mentioned bone conduction hearing-aid glasses, the support plate has an inverted U-shaped structure, and the bottom end of one side wall of the support plate is fixedly connected to the first hearing aid.

[0010] In a specific embodiment of the above-mentioned bone conduction hearing-aid glasses, a plurality of connecting suction cups are provided on the temples, and the connecting suction cups are located between the temples and the support arms.

[0023] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0026] The present invention relates to the technical field of smart wearable devices, and in particular to bone conduction hearing-aid glasses. The goal is to address the problem that existing bone conduction hearing-aid glasses require the hearing aid module to be in close contact with the user's head to effectively transmit sound. However, current frame designs struggle to ensure a consistently close fit, impacting sound transmission and resulting in a poor user experience. Furthermore, prolonged contact between the single hearing aid module and the head can easily cause skin injuries at the site of compression, reducing user comfort. To this end, the present invention provides bone conduction hearing-aid glasses, comprising a frame and lenses, wherein the lenses are mounted on the frame, and further comprising a first hearing aid, a second hearing aid, a support arm, and temples. The two ends of the frame are respectively hinged with connecting parts, the end of the connecting part away from the frame is connected to the support arm, and the end of the support arm away from the frame is connected to the temple. The support arm is a hollow structure and a driving mechanism is installed inside it. The bottom end of the driving mechanism extends to the outside of the support arm and is connected to the first hearing aid. The driving mechanism is configured to drive the first hearing aid to perform reciprocating linear motion in a direction perpendicular to the support arm under the action of an external force, and the second hearing aid is mounted on the temples. The driving mechanism designed in the present invention can drive the first hearing aid to move in a direction close to or away from the head, so that the position of the first hearing aid can be adjusted according to different head shapes, so that the first hearing aid can maintain a fit with the head when worn. In addition, two pairs of hearing aids can work simultaneously, which helps to improve the hearing aid effect.

[0027] The bone conduction hearing aid glasses provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] See Figure 1 The present invention provides bone conduction hearing-aid glasses, comprising a frame 1 and a lens 2, wherein the lens 2 is mounted on the frame 1. The glasses also include a first hearing aid 11, a second hearing aid 12, a support arm 4, and temples 6. Connectors 3 are hingedly connected at both ends of the frame 1. The end of the connector 3 away from the frame 1 is connected to the support arm 4, and the end of the support arm 4 away from the frame 1 is connected to the temples 6. The support arm 4 is a hollow structure and has a drive mechanism installed therein. The bottom end of the drive mechanism extends to the outside of the support arm 4 and is connected to the first hearing aid 11. The drive mechanism is configured to drive the first hearing aid 11 to perform reciprocating linear motion in a direction perpendicular to the support arm 4 under the action of an external force. The second hearing aid 12 is mounted on the temples 6. The support arm 4 is a rectangular parallelepiped structure.

[0029] In the above embodiment, preferably, refer to Figure 1 A docking seat 8 is provided on the temple 6, and the second hearing aid 12 is installed on the side wall of the docking seat 8 facing the inner side of the glasses. The inner wall of the docking seat 8 fits with the temple 6 and can drive the second hearing aid 12 to move along the temple 6 under the push of external force. A wire groove is provided on the side wall of the temple 6 facing the inner side of the glasses, which is connected to the inside of the support arm 4.

[0030] Specifically, the docking seat 8 is made of medical silicone material, so that the docking seat 8 can tightly wrap the temple 6 and cannot move when not subject to external force. At the same time, it is also elastic, and the docking seat 8 can also be moved along the temple 6 by manual pushing, thereby achieving the purpose of moving and positioning the second hearing aid 12.

[0031] Regarding the shape of the docking seat 8, this application does not make any specific restrictions and it is flexibly set according to actual usage. For example, the docking seat 8 is a cylindrical or rectangular structure with a through hole in the middle for the temple 6 to pass through.

[0032] In one embodiment, see Figure 2 、 Figure 4 and Figure 5 The driving mechanism includes a screw 19, a driving gear 1713 and a support plate 18. The screw 19 is rotatably connected to the inside of the support arm 4. The support plate 18 is threadedly connected to the screw 19. The bottom end of the support plate 18 passes through the support arm 4 and is fixedly connected to the first hearing aid 11. The driving gear 1713 is fixed to the screw 19 on one side of the support plate 18. The bottom end of the driving gear 1713 extends to the outside of the support arm 4. When driven by an external force, the driving gear 1713 can drive the screw 19 so that the support plate 18 drives the first hearing aid 11 to move linearly in a direction perpendicular to the support arm 4.

[0033] Specifically, the axis of the screw 19 is perpendicular to the center line of the length direction of the support arm 4, and a stepped opening is provided on the bottom wall of the support arm 4 at a position corresponding to the driving mechanism. The opening is used for the driving gear 1713 and the support plate 18 to pass through, and the gap between the inner wall of the opening for passing through the support plate 18 and the support plate 18 is small, for example, 1-2 mm. In this way, the driving gear 1713 can be manually driven to drive the screw 19 inside the support arm 4 to rotate. During this process, the support plate 18 can only move in a straight line due to the restriction of the opening, thereby realizing the function of controlling the driving gear 1713 to drive the first hearing aid 11 to move.

[0034] In the above embodiment, preferably, refer to Figure 5 The support plate 18 has an inverted U-shaped structure, with the bottom end of one side wall of the support plate 18 fixedly connected to the first hearing aid 11. The wires used to connect to the first hearing aid 11 pass through the inner side of the support plate 18 and into the support arm 4. These wires are used to connect to the control circuit board 15 described below, thus concealing the wires and improving the overall appearance of the glasses.

[0035] In the above embodiment, the driving mechanism designed in the present application can drive the first hearing aid 11 to move in a direction close to or away from the head, so that the position of the first hearing aid 11 can be adjusted according to different head shapes, thereby enabling the first hearing aid 11 to maintain a close fit with the head when worn. In addition, two pairs of hearing aids can work simultaneously, which helps to improve the hearing aid effect.

[0036] In one embodiment, see Figure 1 A first mechanical screw 145 is connected to the side wall of the support arm 4 facing the inner side of the glasses, and the end of the connecting member 3 away from the frame 1 is passed through the inside of the support arm 4 and is fixed to the support arm 4 by squeezing the first mechanical screw 145.

[0037] Specifically, because the support arm 4 has a relatively thin wall, to ensure that the first machine screw 145 can be stably mounted on the support arm 4, a connecting block 22 is fixed to the inner wall of the support arm 4 at the location where the first machine screw 145 is mounted. The first machine screw 145 passes through the first connecting block 22 and is threadedly connected thereto. The tail end of the first machine screw 145 is screwed against the connector 3, thereby securing it to the support arm 4 through compression. The connector 3 is a rectangular parallelepiped structure, so that the tail end of the first machine screw 145 can completely conform to the wall of the connector 3, ensuring compression stability.

[0038] In one embodiment, see Figure 3 A U-shaped notch 20 is provided on the side wall of the end of the connecting member 3 away from the frame 1, and protrusions 21 are extended outward on the top and bottom walls of the end of the connecting member 3 away from the frame 1, and the spacing between the protrusions 21 is greater than the width of the connecting member 3.

[0039] Specifically, the number of U-shaped notches 20 can be two, and a first insertion port is provided on the side wall at one end of the support arm 4 for the end of the connector 3 to pass through to enter the support arm 4. The height of the first insertion port is also smaller than the distance between the two protrusions 21. In this way, when the end of the connector 3 is inserted into the support arm 4, due to the provision of the U-shaped notch 20, the end can be deformed by extrusion, thereby shortening the overall width so as to be smoothly inserted from the first insertion port. After insertion, the end is not subject to the extrusion force and returns to its original shape. At this time, the distance between the two protrusions 21 is greater than the height of the first insertion port, which plays a limiting role. When not subject to external force, the connector 3 cannot be pulled out of the support arm 4, thereby preventing the glasses from falling apart as a whole.

[0040] In one embodiment, see Figure 1 The temples 6 are fitted with multiple connecting suction cups 7, located between the temples 6 and the support arms 4. These are made of medical-grade silicone. The spacing between adjacent suction cups 7 can be adjusted based on usage. During wear, the suction cups 7 maintain a firm grip on the wearer's head, enhancing wearing stability. The suction cups 7 are removable and can be replaced.

[0041] A second insertion port is provided at one end of the support arm 4 away from the frame 1 for inserting one end of the temple 6 . After one end of the temple 6 is inserted into the support arm 4 , it is connected and fixed by a second machine screw.

[0042] In one embodiment, see Figure 1 and Figure 4 A microphone 10 is embedded on the side wall of the support arm 4 facing away from the inner side of the glasses. The microphone 10 is an omnidirectional microphone 10.

[0043] Specifically, the sidewall of the support arm 4, facing away from the inner side of the glasses, is provided with an inwardly recessed groove 23. An elastic sleeve is wrapped around the outside of the microphone 10, which is clamped into the groove 23 by the elastic sleeve. The elastic sleeve can be made of silicone and is squeezed into the groove 23. The bottom wall of the groove 23 is in contact with the connector 3 inside the support arm 4, thereby cooperating with the first machine screw 145 to clamp and secure the connector 3.

[0044] In one embodiment, see Figure 2 A control circuit board 15, a geared potentiometer, and a power module 16 are provided inside the support arm 4. The control circuit board 15 is fixed inside the support arm 4. The geared potentiometer and power module 16 are both mounted on the control circuit board 15. The power module 16 provides power to the control circuit board 15. The geared potentiometer, microphone 10, first hearing aid 11, and second hearing aid 12 are all connected to the control circuit board 15. The adjustment gear 9 on the geared potentiometer extends to the outside of the support arm 4. The volume of the first hearing aid 11 and the second hearing aid 12 can be adjusted by rotating the gear on the geared potentiometer. A charging port 24 for charging the power module 16 is provided at the bottom of the support arm 4.

[0045] This application does not specify the control circuit board, which can be flexibly configured based on actual usage requirements. For example, the control circuit board model is RTL8773DO-VHA-EVB. Sound information received by the microphone is processed by the control circuit board and then transmitted to the first hearing aid and the second hearing aid.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the protection scope of the technical solutions of the various embodiments of the present invention.
