The article proposes a structure for building smart glasses based on a powerful SoC using the bone path for sound. Modern smart glasses are available to perform from certain professional jobs to the everyday. The model discussed in the article refers to casual glasses and assumes that the user needs a set of only the most common basic functions, which will help to achieve the perfect balance. The development was based on an analysis of the wearable electronics market and the study of popular features among users. The choice of a useful set of eyewear functions for everyday users of wearable electronics is justified, which will allow them to create a more compact design, and the transmission of sound through the bone - mastoid will provide increased safety of the user and improve auditory sensitivity. This will allow you to hear better in people's places where the sound from ordinary speakers is simply not heard. Speaker sound is an acoustic signal that can silence another sound from a louder source. The main task is to choose a set of components that will reduce the number of components of the finished board. Companies that manufacture such products usually develop their own calculator, a processor that will operate the glasses and process the necessary information. The use of SoC's own design for wearable electronics has a positive effect on the portable device's energy efficiency and reliability due to reduced component use and reduced overall dimensions. After all, you can use ready-made solutions. They will also have everything you need to integrate into a technical solution of this type, but their problem is their versatility, which means you need to customize to the developer's requirements. The structural scheme of application use SoC by Qualcomm company with a piece in devices of this type is presented. Qualcomm's SoC is available for development, leading the way in creating similar solutions for mobile platforms and with a large selection of affordable products. QCC302x / QCC303x or QCC5100 family may be integrated into the structure. The circuit, in addition to the processor, includes the use of the necessary external peripherals as amplifiers, 2 microphones, a touch control panel, antenna and antenna filter, a battery and a battery management system. The proposed structure provides for the implementation of smart glasses, which will be structurally close in shape to regular glasses and will have only the most required user basic features. This will reduce the cost of the device and make it accessible to a much larger number of users. The use of bone conduction sounds will positively improve information transfer regardless of the user's location. And having a voice assistant will allow you to quickly get the information you need without touching your smartphone.
