Description

Technical Field

[0001] This utility model relates to the field of smart glasses technology, and in particular to a smart glasses with bone conduction headphones. Background Technology

[0002] With the development of science and technology, smart glasses are becoming increasingly widely used in daily life. Current smart glasses generally include an earphone and microphone for call functionality. However, the earphones used in most smart glasses on the market today are air-conduction earphones. These earphones utilize air vibrations to transmit sound to the eardrum, allowing users to hear. To avoid sound leakage and privacy breaches, users need to insert the earphones into their ears. Prolonged use can cause tinnitus and other problems, and in severe cases, even hearing loss, which is detrimental to the user's health.

[0003] Therefore, some smart glasses using bone conduction headphones have emerged in the existing technology. For example, patent number CN207601447U proposes a pair of glasses with a bone conduction speaker. This pair has a bone conduction speaker installed at the back of the temple, and a rubber side plate protruding outwards to cover the speaker on the inner side of the temple. The vibration of the bone conduction speaker is transmitted to the facial bones through the rubber side plate, thus transmitting sound to the user. However, these smart glasses often experience discomfort and poor sound quality when worn. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a smart glasses with bone conduction headphones.

[0005] A smart glasses with bone conduction headphones includes: a frame; lenses symmetrically embedded in the frame; temples rotatably disposed at the left and right ends of the frame; bone conduction headphones rotatably disposed on the two opposite outer surfaces of the temples, and capable of rotating relative to the temples about an axis extending in the left-right direction; and electronic components including a first electronic unit disposed in the frame and a second electronic unit disposed in the temples; the first electronic unit, the second electronic unit, and the bone conduction headphones are sequentially electrically connected to form a closed electronic circuit.

[0006] The smart glasses with bone conduction headphones described in this utility model have the bone conduction headphones placed on the outer side of the temples. This prevents them from pressing against the user's skull and causing discomfort during use. At the same time, they can rotate relative to the temples to adapt to the needs of users with different face shapes, ensuring that the vibrating pads inside the bone conduction headphones maintain good contact with the user's skull and guaranteeing sound quality.

[0007] Furthermore, the smart glasses with bone conduction headphones also include a connecting shaft, which protrudes along the left-right direction on the two opposite outer surfaces of the two temples and extends away from the temples; the bone conduction headphones include a connecting part and a sound transmission part, one end of the connecting part is sleeved on the outside of the connecting shaft and rotatably connected thereto, and the other end is connected to the sound transmission part, and the sound transmission part is provided with a vibrating plate.

[0008] The above technical solution enables bone conduction headphones to rotate around the connecting shaft, allowing users to easily adjust the viewing angle.

[0009] Furthermore, the smart glasses with bone conduction headphones also include a first limiting member and a second limiting member, the first limiting member and the second limiting member being sleeved on the connecting shaft, and the connecting portion being clamped between the first limiting member and the second limiting member along the extending direction of the connecting shaft.

[0010] Through the above technical solution, the first limiting member and the second limiting member limit the connecting part, preventing the bone conduction from coming off the connecting shaft when the angle is adjusted by rotation, and making the angle of the bone conduction headphones less likely to change.

[0011] Furthermore, the distance from the axis of the connecting shaft to the end of the sound transmission part away from the connecting shaft is 32-35 mm.

[0012] The above technical solution ensures that when the user uses the bone conduction headphones, the end furthest from the connecting shaft can fit against the user's earlobe bone, resulting in better sound transmission.

[0013] Furthermore, the outer side of the temple facing away from the other temple has a receiving groove that communicates with the outside below. The receiving groove extends along the length of the temple and its length is greater than the length of the bone conduction headphones. The bone conduction headphones are disposed in the receiving groove.

[0014] The above technical solution allows for the storage and protection of bone conduction headphones, while also resulting in a sleek and minimalist design for the smart glasses.

[0015] Furthermore, the rear end of the temple is provided with a corner portion and a rear extension portion. The corner portion is in the shape of an upwardly convex arc. The rear extension portion is connected to the end of the corner portion away from the frame and extends downward at an angle.

[0016] The above technical solution allows the corner part to fit into the back of the ear, making it convenient for users to fix the position of the glasses when wearing them.

[0017] Furthermore, the second electronic unit includes a motherboard, a wireless communication module, a microphone module, a volume control module, a sensing module, and a power module; the bone conduction headphones, the wireless communication module, the microphone module, the volume control module, the sensing module, and the power module are respectively electrically connected to the motherboard.

[0018] Furthermore, the smart glasses with bone conduction headphones also include a power switch, which is located on the upward-facing side of the temple and electrically connected to the mainboard.

[0019] The above technical solution uses an on / off switch to control the smart glasses.

[0020] Furthermore, it also includes volume control buttons, which are located on one side of the temple and electrically connected to the volume control module.

[0021] Furthermore, the frame is also provided with two nose pads, which are spaced apart on the left and right sides along the center line of symmetry of the frame.

[0022] The above technical solution allows the nose pads to work together with the sides of the nose bridge to provide support, making it easier for users to secure their glasses when wearing them. Attached Figure Description

[0030] The applicant conducted research and analysis on existing smart glasses with bone conduction headphones and found that the main reason for the discomfort and poor sound quality of existing smart glasses is that the vibrating plate of the bone conduction speaker can only contact the skull near the back of the user's ear. The position of the vibrating plate cannot be adjusted according to the user's face shape. Users with different face shapes may experience poor contact, resulting in poor sound quality. At the same time, the protruding side plate presses against the user's skull for a long time, which can easily cause discomfort and affect the user's experience.

[0031] In response to the above findings, this invention provides smart glasses with bone conduction headphones. The bone conduction headphones are rotatably mounted on the outer surfaces of the two temples facing away from each other, allowing the unfolding angle of the headphones to be adjusted according to the user's face shape. This ensures good contact between the vibrating pads and the user's skull, thereby improving sound quality. Simultaneously, the bone conduction headphones do not press against the user's skull during use, thus avoiding discomfort. The following is one embodiment of the smart glasses with bone conduction headphones provided by this invention:

[0032] Please refer to Figures 1 to 7 , Figure 1 A schematic diagram of the spatial structure of the smart glasses with bone conduction headphones provided by this utility model; Figure 2 The right view of the smart glasses with bone conduction headphones provided by this utility model, projected along the front-to-back direction when the bone conduction headphones are in the storage state; Figure 3 The right view of the smart glasses with bone conduction headphones provided by this utility model, projected along the front-back direction when the bone conduction headphones are in the unfolded state; Figure 4 A bottom view of the smart glasses with bone conduction headphones provided by this utility model, projected along the front-to-back direction. Figure 5 for Figure 4 Enlarged view of point A in the middle; Figure 6 for Figure 4 Enlarged view of point B in the middle; Figure 7 A schematic diagram of the module structure of the second electronic unit provided by this utility model.

[0033] Specifically, when a user wears the bone conduction smart glasses, the user's face is facing forward, and the user's back is the rear; the user's left and right sides are the left and right sides, and the user's top and bottom sides are the top and bottom sides, respectively; at this time, the frame 1 is located at the front end of the temple 3, the temple 3 extends in the front-back direction, and the symmetrical center line of the frame 1 is located in the middle of the frame 1 and extends in the top-bottom direction.

[0034] This invention provides smart glasses with bone conduction headphones, including a frame 1, lenses 2, temples 3, a connecting assembly 4, bone conduction headphones 5, and electronic components (not shown). The frame 1 has two temples 3 and two lenses 2, each embedded within the frame 1 and mirror-imaged along the center line of symmetry of the frame 1. The two temples 3 are rotatably positioned at the left and right ends of the frame 1, mirror-imaged along the center line of symmetry of the frame 1. The temples 3 can be unfolded or folded relative to the frame 1 for easy storage and use. The frame 1 and temples 3 are hollow. The electronic components may include circuit boards, music players, and cameras, which implement various functions in the prior art, and are respectively disposed within the frame 1 and temples 3. The bone conduction headphones 5 are rotatably mounted on the temples 3 via the connecting assembly 4 and are electrically connected to the electronic components.

[0035] Furthermore, the frame 1 is also provided with two spaced nose pads 11, which are mirror images of each other along the center line of symmetry of the frame 1. When the user wears the smart glasses with bone conduction headphones, the nose pads 11 contact the user's bridge of the nose to form support, which facilitates the fixation of the smart glasses with bone conduction headphones.

[0036] Each temple 3 has a corner portion 31 and a rear extension portion 32 at its rear end. The corner portion 31 is an upwardly convex arc shape, and the rear extension portion 32 is connected to the end of the corner portion 31 away from the frame 1 and extends downward at an angle. When the user wears the smart glasses with bone conduction headphones, the corner portion is located above the user's ear, and the corner portion 31 hooks around the user's ear, together positioning the temple 3 behind the ear. At the same time, the two temples 3 cooperate with each other to provide a certain clamping force to the head, making the smart glasses with bone conduction headphones more stable and less likely to fall off after wearing.

[0037] The connecting component 4 is disposed at the rear end of the temple 3. In the front-rear direction, the connecting component 4 is located in front of the corner portion 31, that is, the corner portion 31 is located between the connecting component 4 and the rear extension portion 32. The connecting component 4 includes a connecting shaft 41, a first limiting member 42, and a second limiting member 43. Specifically, the connecting shaft 41 protrudes from the two opposite outer surfaces of the two temples 3. The connecting shaft 41 is perpendicular to the outer surfaces of the two temples 3 and extends in a direction away from the two temples 3, that is, in the left-right direction. The first limiting member 42 and the second limiting member 43 are sleeved on the connecting shaft 41 and spaced apart along the extending direction of the connecting shaft 41. The bone conduction earphone 5 is located between the first limiting member 42 and the second limiting member 43. The first limiting member 42 is located on the side closer to the temple 3 and contacts the plate surface of the temple 3. By clamping the bone conduction earphone 5 in the middle of the temple 3 by the first limiting member 42 and the second limiting member 43, the damping can be increased, so that the bone conduction earphone 5 can maintain a certain angle relative to the temple 3. Preferably, the first limiting member 42 and the second limiting member 43 are damped elastic members. In this embodiment, the first limiting member 42 and the second limiting member 43 are cylindrical stop blocks. In other embodiments, the first limiting member 42 and the second limiting member 43 can also be other shapes that can achieve the limiting effect on the bone conduction earphone 5, and are not limited to this.

[0038] The bone conduction headphones 5, used for playing sound, include a connecting part 51 and a sound transmitting part 52. One end of the connecting part 51 is sleeved on the outside of the connecting shaft 41 and rotatably connected thereto, while the other end is connected to the sound transmitting part 52. In the extending direction of the connecting shaft 41, the connecting part 51 is sandwiched between the first limiting member 42 and the second limiting member 43, and the left and right end faces of the connecting part 51 respectively abut against the first limiting member 42 and the second limiting member 43, preventing the bone conduction headphones 5 from dislodging from the connecting shaft 41 when rotating relative to the temple 3 with the connecting shaft 41 as its axis. The sound transmitting part 52 contains a vibrating plate, and the unfolding angle of the sound transmitting part 52 can be adjusted according to the user's needs to ensure good contact between the vibrating plate and the user's skull.

[0039] Preferably, the distance from the axis of the connecting shaft 41 to the end of the sound transmission part 52 away from the connecting shaft 41 is 32-35mm, so that when the user wears the smart glasses with bone conduction headphones, the bone conduction headphones 5 can be rotated as needed, and the end of the bone conduction headphones 5 away from the connecting shaft 41 can fit against the user's earlobe bone, resulting in better sound transmission through bone conduction.

[0040] Furthermore, a receiving groove 33 is provided on the outer side facing away from the other temple 3. The receiving groove 33 extends along the length direction of the temple 3, and the length of the receiving groove 33 is greater than the length of the bone conduction earphone 5. The lower part of the receiving groove 33 communicates with the outside, and the connecting component 4 and the bone conduction earphone 5 are disposed in the receiving groove 32. When the user does not need to use the bone conduction earphone 5, the bone conduction earphone 5 is rotated around the connecting shaft 41 and put into the receiving groove 33 for safekeeping.

[0041] The electronic components include a first electronic unit (not shown) disposed within the frame 1 and a second electronic unit (not shown) disposed within the temples 3, the first and second electronic units being electrically connected. In this embodiment, the first electronic unit is a cable of the prior art, electrically connected to the second electronic units of the two temples 3 respectively to form a closed loop for current transmission. The second electronic unit includes a main board 301, a wireless communication module 302, a microphone module 303, a volume control module 304, a sensing module 305, and a power module 306. The bone conduction headphones 5, the wireless communication module 302, the microphone module 303, the volume control module 304, the sensing module 305, and the power module 306 are all electrically connected to the main board 301.

[0042] The motherboard 301 is a high-performance main chip in the prior art, such as the Unisoc W517 or MTK8788, used for signal processing and controlling the operation of various modules. The wireless communication module 302 is Bluetooth Low Energy in the prior art, which communicates with the mobile terminal and receives communication signals from the mobile terminal. The microphone module 303 is a microphone array in the prior art, used for sound pickup. The volume adjustment module 304 is used to adjust the volume. The sensing module 305 is a MEMS sensor in the prior art, used to receive the user's tapping signals. The power module 306 is a lithium-ion battery in the prior art, used to power the smart glasses with bone conduction headphones.

[0043] Furthermore, the bone conduction smart glasses also include a power switch 6, which is located on the upward-facing side of the temple 3 and electrically connected to the main board 301. The user controls the opening and closing of the bone conduction smart glasses by clicking the power switch 6.

[0044] Furthermore, the smart glasses with bone conduction headphones also include a volume control button (not shown). The volume control button is located on one side of the temple 3 and is electrically connected to the volume control module 304. Users can increase or decrease the volume by touching and sliding the volume control button.

[0045] Furthermore, the main board 301 is disposed at the rear end of the temple 3. In the length direction, the main board 301 is located behind the corner portion 31, thereby reducing the width of the front end of the temple 3 and improving the aesthetics of the smart glasses with bone conduction headphones.

[0046] The working principle of the smart glasses with bone conduction headphones provided by this utility model is as follows: The user wears the smart glasses with bone conduction headphones, and the end of the bone conduction headphones 5 away from the connecting shaft 41 is in contact with the user's earlobe bone. When the mobile terminal receives an incoming call, the prompt tone is transmitted to the main board 301 via the wireless communication module 302, converting the sound signal into an electrical signal and outputting the electrical signal to the bone conduction headphones 5. The bone conduction headphones 5 convert the electrical signal into a vibration signal and transmit it to the user. The user taps the smart glasses with bone conduction headphones a certain number of times to select whether to answer or reject the call. The sensing module 305 receives the user's tapping signal and transmits it to the main board 301. The main board 301 selects whether to answer or reject the call according to the pre-stored processing program. When the user answers a call, the principle of sound signal conversion and transmission is the same as above.

[0047] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
