DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0017] Reference Figure 1-3 The precise navigation guide earphone device includes a base 1, which is semicircular. Through the setting of the base 1, the base 1 can support the guide earphone, which is convenient for people to place the guide earphone and improves the adaptability of the device. Compared with most powerful but bulky and heavy guide aids (such as mobile guide instruments, guiding canes, and wearable guide instruments), the smart guide earphone is small in size and easy to carry, and will not add too much burden to the blind when traveling.

[0018] The top of the base 1 is equipped with a connecting plate 2, which is curved. The top end of the connecting plate 2 is equipped with a headphone holder 3. A telescopic plate 4 is slidably connected to the lower ends of both sides of the headphone holder 3. The lower ends of both telescopic plates 4 are equipped with earmuffs 5. A detection head 6 is installed at the front end of the headphone holder 3. It uses ultrasonic sensors, infrared sensors, and ultrasonic rangefinders to capture human bodies and sounds, improving obstacle recognition, timely and accurately detecting obstacles, and notifying the user through voice prompts and other methods to help them avoid them safely. A human-computer communication mode is added, which can provide voice prompts to guide users to avoid obstacles safely. It also has a telephone communication and alarm system, allowing users to contact their families in a timely manner and send out distress signals in case of danger. The smart guide headphones use Beidou positioning technology to achieve real-time positioning and navigation, accurately finding the user's location to prevent them from getting lost. It also provides travel route navigation and location recognition functions, giving blind people a better sense of direction when traveling.

[0019] A through groove 7 is provided between the two ends of the base 1, and a connecting mechanism for connecting the two ends of the base 1 is provided in the through groove 7. The connecting mechanism includes a movable plate 8 that is slidably connected to the two ends of the through groove 7. The movable plate 8 is annularly arranged, and a slot 9 is provided at the end of the left movable plate 8, and an insert block 10 that cooperates with the slot 9 is provided at the end of the right movable plate 8. By making the slots 9 and the insert block 10 on the opposite sides of the two movable plates 8 coincide with each other, the base 1 is put on the neck. While the operation is simple, the base 1 will not fall off, thereby reducing the occurrence of the earphones falling off due to external reasons.

[0020] The wall of the through groove 7 is provided with a limiting mechanism for limiting the connecting mechanism. The limiting mechanism includes grooves 11 opened on the groove walls on both sides of the through groove 7. Guide rods 12 are provided in the two grooves 11. The outer walls of the two guide rods 12 are slidably connected with two symmetrically arranged sliders 13. The two sliders 13 are respectively connected to the two movable plates 8. This design makes it difficult for the headphones to fall off when worn by a blind person.

[0021] Two symmetrically arranged rotating shafts 15 are rotatably connected to the through slot 7 , and transmission wheels 17 are provided on the outer walls of the two rotating shafts 15 , and the two transmission wheels 17 are meshed with each other.

[0022] An incomplete bevel gear ring 14 is provided on the upper end of the two movable plates 8 , and a bevel gear 16 meshing with the incomplete bevel gear ring 14 is provided on the outer wall of the two rotating shafts 15 .

[0023] One of the rotating shafts 15 passes through the rear end of the base 1 and is rotatably connected thereto. A damping gasket is provided at the rotational connection between one of the rotating shafts 15 and the rear end of the base 1. The damping gasket limits the position of the rotating shaft 15 after rotation to avoid loose connection.

[0024] When the present invention is used, when the guide earphone is used, the earphone frame 3 is first placed on the head, so that the two earmuffs 5 are placed on the ears. At this time, one of the rotating shafts 15 at the rear end of the base 1 is rotated (the damping gasket limits the position of the rotating shaft 15 after rotation). Under the meshing action of the transmission wheels 17 between the two rotating shafts 15, the two transmission wheels 17 drive the two rotating shafts 15 to move at the same speed but in different directions, thereby rotating the bevel gears 16 on the outer walls of the two rotating shafts 15. Then, by meshing the bevel gears 16 with the incomplete bevel gear ring 14 and sliding connection of the multiple sliders 13 with the guide rod 12, the incomplete bevel gear ring 14 is moved. The movable plate 8 is driven by the movement, so that the two movable plates 8 move at both ends of the through slot 7 respectively, so that the slots 9 on the opposite sides of the two movable plates 8 overlap with the insert block 10, thereby putting the base 1 on the neck. While the operation is simple, the base 1 will not fall off, thereby reducing the phenomenon of the earphone falling off due to external factors. In addition, the configuration of the base 1 enables the base 1 to support the guide earphone, making it easier for people to place the guide earphone and improving the adaptability of the device. With the continuous advancement of science and technology, smart guide earphones also have a broader development space. In the future, they can be combined with artificial intelligence and Internet of Things technologies to make them more intelligent and humanized. For example, based on machine learning algorithms, they can learn users' walking habits and preferences to provide more personalized navigation suggestions; they can also be integrated with smart home systems to help blind people control home devices more conveniently, further improving their quality of life.
