Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, specifically to a smart earphone. Background Technology

[0002] With the widespread adoption of smart devices and the diversification of lifestyles, headphones have become an indispensable electronic accessory in modern life. Traditional headphones primarily function for audio playback, used for music enjoyment, voice calls, and media entertainment, with sound reproduction quality and wearing comfort being their core design considerations. However, as user scenarios continue to expand, more and more people are accustomed to wearing headphones during outdoor activities, such as commuting, walking in parks, hiking, mountain climbing, and running. The use of headphones has extended from static, safe indoor environments to dynamic and complex outdoor environments.

[0003] In these outdoor scenarios, prolonged use of traditional headphones poses significant safety hazards. Because traditional headphones typically isolate external sounds through their in-ear or over-ear design, users' ability to perceive ambient noise is greatly reduced. When users are immersed in music or conversations, they are prone to overlooking crucial ambient sound information, such as vehicle horns, pedestrian warnings, road construction alerts, approaching animals, or other sudden danger signals. This "shielding" effect on auditory perception distracts users, reduces their ability to respond to environmental changes, and thus increases the risk of traffic accidents or accidental injuries.

[0004] This risk is particularly pronounced in busy urban roads, areas with mixed pedestrian and vehicular traffic, or complex natural environments. Numerous cases have demonstrated that pedestrians wearing headphones have caused accidents while crossing the street or cycling because they failed to notice approaching vehicles in time. Therefore, while traditional headphones provide auditory enjoyment, they also pose significant safety concerns. Utility Model Content

[0028] By integrating multiple sensors, communication modules, and image acquisition units, and achieving wireless collaboration with mobile devices, it breaks through the functional limitations of traditional headphones as merely audio playback devices. It achieves a deep integration of intelligent perception, environmental interaction, and proactive safety protection, significantly improving user safety and intelligent experience in complex environments.

[0029] By using a gravity sensor to detect changes in the position of the headphones and the user's movement status (such as walking, running, or standing still) in real time, and combining this with the analysis of the control circuit, the system can intelligently determine the user's activity scenario and provide a basis for decision-making in subsequent function adjustments.

[0030] The light sensor communicates efficiently with the control circuit via the I²C protocol, featuring high response speed and low power consumption. It is primarily used to detect the wearing status of the headphones. For example, when the user removes the headphones, it can automatically play / pause audio, dynamically wake up / put into sleep mode, etc., optimizing the human-computer interaction experience while effectively reducing power consumption when not wearing the headphones. The light sensor can also sense environmental parameters such as external light intensity, and combined with algorithms, it can achieve adaptive adjustments based on the environment. For example, it can automatically adjust the prompt volume or trigger specific modes in strong or low light environments, enhancing the device's adaptability to complex usage scenarios.

[0031] With an integrated wide-angle camera module, the system can capture real-time images of the surrounding environment of the headphones. When users are walking, cycling, or crossing the road outdoors, the system can detect potential hazards (such as rapidly approaching vehicles or obstacles) through image recognition technology and issue proactive safety warnings to users through audio prompts, significantly reducing the safety risks caused by a lack of environmental awareness due to immersive listening.

[0032] This smart earphone supports dual-mode communication via Bluetooth and Wi-Fi. It establishes a low-latency audio connection with the mobile device through the Bluetooth module, ensuring basic calls and music playback. The Wi-Fi module enables high-speed data transmission, supporting the uploading of images captured by the first and second cameras or data from the gravity sensor to the cloud or mobile device for AI analysis, expanding intelligent application scenarios (such as real-time navigation assistance, environmental recording, emergency alarms, etc.).

[0033] Specifically, this application proposes a smart earphone with environmental perception and intelligent interaction capabilities. It has a built-in high-definition wide-angle camera module, a low-power Bluetooth module, a WIFI module and a microphone module. Through gravity sensor, light sensor and wireless communication technology, it can realize real-time perception and intelligent response to the user's surrounding environment.

[0034] In practical use, these smart earphones utilize a first camera and a second camera, respectively located on the left and right earpieces, to capture and input stereoscopic images of the user's surroundings. The earphones establish a wireless connection with a mobile app via a Bluetooth module (such as BLE) or a Wi-Fi module, and collaborate with a cloud-based AI platform to build an integrated "device-edge-cloud" intelligent system.

[0035] When a user wears headphones and plays music, the wide-angle camera captures real-time images of the environment in front of and to the sides, transmitting video streams or keyframe data to a mobile app via Bluetooth or Wi-Fi. The app then uploads the image information to a cloud-based AI platform for intelligent analysis, identifying potential risks or specific scenarios and providing real-time feedback to the user's phone. Based on the analysis, the mobile app issues safety alerts to the user via audio prompts through the headphones, helping them to detect dangers and take appropriate action without interrupting their music experience, effectively preventing accidents.

[0036] Specific application scenarios include, but are not limited to: When obstacles such as puddles, potholes, or uneven road surfaces are detected in the direction of travel, the system automatically lowers the music volume and plays voice prompts such as "The road surface ahead is uneven, we suggest you detour." The volume is restored to the original level after the user passes through. When a vehicle, bicycle, or electric vehicle is detected approaching rapidly from the side or rear, a warning such as "Vehicle approaching from behind, please be careful" is issued promptly. When a fire source, smoke, or other safety hazard is detected, an emergency alert is immediately issued, reminding users to quickly move away from the danger zone.

[0037] As the AI ​​model continues to learn and optimize, the range of scenes the system can recognize is constantly expanding. Users can also customize the training process to enable the system to recognize specific environmental features, such as special lights, warning signs, and specific objects, thus achieving personalized scene alerts.

[0038] Furthermore, these smart earphones also offer high-precision assisted navigation. When the user uses a navigation app, the camera collects real-time road environment information. At key intersections or complex road sections, the system can provide more accurate and user-friendly voice guidance, for example: "Please wait for the red light at the intersection"; "Green light is on, please proceed quickly"; "There are no traffic lights at the intersection ahead. Please be careful of oncoming vehicles when crossing the road." "Go straight across the road"; "Turn left at the intersection ahead"; "After turning right, follow the path next to the billboard." "Turn right immediately after reaching the billboard," etc.

[0039] Compared to traditional navigation that relies solely on GPS positioning, this solution combines visual perception, significantly improving navigation accuracy and contextual awareness, acting like a "guide" to provide users with real-time guidance.

[0040] Meanwhile, the headphones also support intelligent encyclopedia interaction. When users are interested in the surrounding scenery (such as flowers, trees, artworks, buildings, etc.), they can initiate interaction through voice commands, such as: "What kind of flower is this?" or "Please describe this painting." The system combines images captured by the camera with AI recognition capabilities to quickly generate voice answers, achieving an intelligent experience of "asking what you see and getting answers instantly."

[0041] In summary, this application, by integrating a wide-angle camera with wireless communication technology, endows smart headphones with the ability to "observe" and "understand" their environment, breaking through the functional limitations of traditional headphones that are limited to audio output. The headphones not only function as music playback devices but also as wearable smart terminals integrating safety warnings, precise navigation, and intelligent question answering, significantly improving users' safety, convenience, and interactive experience during outdoor activities. With the continuous evolution of AI capabilities, its application scenarios will further expand, demonstrating broad technological prospects and application value.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
