Description

1. Purpose of the invention

[0001] The invention serves to combine several previously separate devices – headphones, vision goggles, radio receiver, radio transmitter, FM radio, and Bluetooth headset – into a single, ergonomic, and portable system. The aim is to provide the user with a compact, multifunctional communication and vision solution that can be used both in everyday life and in professional environments. 2. Technical problem

[0002] Current technology offers no solution that combines optical magnification, wireless communication, audio reception, audio transmission, FM radio, Bluetooth connectivity, and lighting in a single device. Users have to carry multiple devices, which is impractical, heavy, and inefficient. Additionally, there is no intuitive way to visually confirm wireless connections. 3. Technical field

[0003] The invention lies in the field of portable electronic devices, in particular: • Audio equipment (headphones, headsets) • Optical systems (vision glasses, magnification aids) • Radio technology (UHF / 2.4 GHz, walkie-talkie) • Communication technology (Bluetooth) • Consumer electronics (FM radio) • Personal assistance systems 4. Object of the invention

[0004] Provision of a compact, modular and multifunctional device that: • Audio reception and transmission enabled • Optical support through foldable viewing glasses offers • Provides radio communication (TX / RX) • Integrated FM radio and Bluetooth • has an LED indicator to confirm the connection • ergonomic and easy to carry 5. Solution to the task

[0005] The task is solved by headphones that integrate the following modules: • Foldable viewing goggles on vertical support arms • RF module (UHF + 2.4 GHz) for bidirectional communication • Bluetooth module for wireless audio connections • FM receiver for radio playback • LED indicator for displaying operating and connection statuses • Integrated and telescopic microphone mechanism • Mini LED lamp for lighting 6. Solution approach of the invention

[0006] The invention combines mechanical, optical, and electronic modules in a single device. The viewing glasses are connected to the upper part of the headphones via foldable support arms. The RF module is located in the ear cup and enables TX / RX operation. An LED on the top indicates operating status and successful radio connections. Bluetooth and FM radio expand the communication options. Microphones enable walkie-talkie functionality. 7. Components 7.1 Mechanical Module • Headphone frame • Ear cups with integrated electronics compartments • Foldable viewing glasses with vertical support arms • Joint mechanism (pin / hinge) • telescopic microphone arm • Housing for LED lamp 7.2 Electrical Module • RF module (UHF + 2.4 GHz) • Bluetooth module • FM receiver • LED indicator (multicolor LED) • LED work lamp • Audio amplifiers and drivers • Internal and telescopic microphones • Battery and charging electronics • Switches (ON / OFF, TX / RX, frequency selection) 7.3 Second embodiment • Additional embodiment of the invention: In-ear wearable single headphone • In addition to the variant described in the main embodiment with headphone headband and integrated viewing goggles, the invention includes a further embodiment in which all electronic functionality is integrated into a single, ear-worn headphone. This embodiment completely dispenses with the viewing goggles and an LED work light, but retains the essential communication and audio functions of the invention. The headphone has a compact housing designed to be worn securely and ergonomically in the outer ear canal while simultaneously accommodating all electronic modules. The in-ear headphones contain a Bluetooth module for wireless audio transmission, an FM receiver for broadcast signals, and a bidirectional radio module enabling wireless communication in the UHF or 2.4 GHz range. At least one integrated microphone is provided for voice transmission; however, this embodiment does not use a telescopically extendable microphone. Power is supplied by a battery housed within the casing, along with its own charging electronics. Operating modes, including Bluetooth connection, FM reception, and radio operation, are controlled via controls integrated into the casing or via a paired external control unit. This embodiment extends the scope of the invention to situations requiring a particularly lightweight, discreet, and compact communication device. Despite the reduced size, multifunctionality is maintained because all essential modules of the main embodiment are integrated in a miniaturized form. The combination of Bluetooth audio, FM reception, and bidirectional radio communication in a single in-ear device represents a technical innovation not found in the prior art and constitutes a significant extension of the invention. 8. Functionality and advantages • Audio reception via Bluetooth, FM or RF • Walkie-talkie function via TX / RX mode • Optical support through foldable viewing glasses • LED indicator for connection status (e.g., UHF coupling) • Illumination of the field of vision by mini-LEDs • working freehand • Compact design replaces several individual devices • Both designs are based on the same basic technical concept of integrating a Bluetooth module, FM receiver and bidirectional radio module into a portable audio device. 9. Compatibility with standard products • compatible with smartphones (Bluetooth) • Compatible with standard UHF walkie-talkies • Compatible with FM radio • Compatible with common chargers (USB-C) 10. Summary of the advantages • multiple devices in one system • Low weight and high mobility • intuitive operation • Simultaneous visual and audible support • Increased safety through LED status indicator • Ideal for tradespeople, technicians, outdoor users, medical personnel 11. State of the art and comparison

[0007] Existing products offer: • Headphones with Bluetooth • FM radios • Walkie-talkies • optical magnifying glasses or glasses

[0008] However, no device exists that combines all these functions in a single, ergonomic system. 12. Comparison to the state of the art

[0009] The invention differs in that: • Integration of optical modules directly into headphones • Combination of RF-TX / RX, FM, Bluetooth and LED signaling • Foldable viewing glasses with precise positioning • Multifunctional use without additional devices 13. Degree of innovation

[0010] The invention represents a new class of device: a personal communication, vision and audio system in a single portable device. 14. Ergonomic and sustainable features • The foldable design reduces the physical strain on the user. • The modular design makes repairs and maintenance easier. • The low energy consumption increases operational efficiency. • Replaceable components extend the lifespan of the device.
