Description

Technical Field

[0001] This application relates to the field of smart wearable device technology, and in particular to an integrated control method for smart glasses that integrates Bluetooth audio and TENS electrical stimulation. Background Technology

[0002] Most Bluetooth audio glasses on the market are currently designed for one-way audio playback or calls, offering limited functionality and failing to meet users' diverse needs for health and wellness therapy. Furthermore, traditional TENS (Technical and Nucleic Acid) therapy devices are generally bulky and lack portability, requiring separate carrying and use, making them unsuitable for everyday wear.

[0003] In existing products, the audio circuit and TENS high-voltage pulse circuit are usually designed with a shared ground, which is prone to serious electrical interference, leading to problems such as popping sounds, noise, and system crashes. In addition, no product has yet achieved a deep integration of "open audio + temple therapy + full-body therapy extension", and there is also a lack of high-security control logic for smart glasses.

[0004] Therefore, the following technical defects still exist: The audio function and the physiotherapy function are independent of each other and cannot be integrated into one, resulting in insufficient portability.

[0005] The high and low voltage circuits share a common ground, resulting in severe interference and poor operational stability.

[0006] The operation process relies on the app, which is not user-friendly for middle-aged and elderly users.

[0007] The physical therapy function lacks a safety protection mechanism and poses risks such as electric leakage, overload, and prolonged stimulation. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the purpose of this application is to provide an integrated control method for smart glasses that combines Bluetooth audio and TENS electrical stimulation. The above-mentioned objective of this application is achieved through the following technical solution: an integrated control method for smart glasses that integrates Bluetooth audio and TENS electrical stimulation, wherein the smart glasses include a Bluetooth audio module, a TENS high voltage module, an isolation device, a button control system, a charging detection circuit and a main control chip; Includes the following steps: S1. The internal circuit of the smart glasses is divided into a Bluetooth audio low-voltage area and a TENS high-voltage pulse area. Electrical isolation and ground isolation are achieved between the two areas through isolation devices to avoid interference of high-voltage pulses on the audio signal. S2. Three physical buttons are installed on the temples to enable button reuse control without the need for an app, including: The first button is used to increase the volume or massage intensity. The second button is used to decrease the volume or reduce the massage intensity. The third button is used for power on / off, Bluetooth pairing, mode switching, and switching between temple therapy and full-body therapy modes. S3. When the charging interface is detected to be connected to a charging power source, the output of the TENS high-voltage module is automatically locked, and the physiotherapy function is prohibited from being started. S4. When the TENS function is enabled, the timer will start automatically and stop the high voltage output automatically after the preset time is reached. S5. The load detection circuit set at the TENS output terminal detects the electrode connection status in real time. If no load is detected or the load is disconnected, the high voltage output is automatically blocked.

[0009] By adopting the above technical solution, firstly, the interference between Bluetooth audio and TENS high-voltage pulse is completely eliminated through electrical isolation, ensuring stable sound quality without popping; secondly, all functions such as volume, intensity, power on / off, and mode switching are realized using three physical buttons, eliminating the need for an APP and making operation extremely simple; at the same time, the high-voltage output is automatically locked during charging to prevent the risk of leakage; after the physiotherapy is turned on, the timer automatically stops after 15 minutes to avoid overstimulation; and the output is automatically blocked when no electrodes are connected to prevent electric shock under no-load conditions.

[0010] Overall, this method achieves both interference-free coexistence of audio and physiotherapy functions and convenient one-button control, while ensuring safety.

[0011] Furthermore, the isolation device is an optocoupler isolator or a digital isolation chip.

[0012] Furthermore, the operating voltage of the Bluetooth audio low-voltage zone is 3.7V, and the output voltage of the TENS high-voltage pulse zone is adjustable from 0-60V.

[0013] By adopting the above technical solutions, the optocoupler uses optical signal transmission to control the on / off state, while the digital isolation chip achieves high and low voltage separation through chip-level capacitors or magnetic coupling. Both can completely cut off the ground loop and electrical coupling path between the Bluetooth low voltage area (3.7V) and the TENS high voltage area (0-60V) electrically.

[0014] Furthermore, in the multiplexing control of the three physical buttons: A short press of the first button increases the volume, while a long press increases the massage intensity. A short press of the second button decreases the volume, while a long press decreases the massage intensity. Press and hold the third button for 3 seconds to turn the device on or off, press it briefly to pair via Bluetooth or switch modes, and double-click to switch between temple therapy mode and full-body therapy mode.

[0015] By adopting the above technical solution, the function of the same button in different modes is naturally distinguished by "short press to adjust volume, long press to adjust intensity," allowing users to operate intuitively based on the duration of the press without any learning. The third button uses a "3-second long press" as a threshold to prevent accidental touches when turning the device on or off, a short press to perform Bluetooth pairing and audio / therapy mode switching, and a double press to quickly switch between temple therapy and full-body therapy modes. This allows the three buttons to fully cover the five core operations of power on / off, pairing, volume adjustment, intensity adjustment, and mode switching without increasing the number of buttons. This logic completely eliminates the dependence on a mobile app, supports blind operation, and is especially suitable for sports, the elderly, or visually impaired scenarios, while avoiding the impact of too many buttons due to function stacking on the temples and wearing comfort.

[0016] Furthermore, the preset timer is 15 minutes.

[0017] Furthermore, the temple therapy mode is achieved through flexible TENS electrodes positioned at the temples of the smart glasses, while the whole-body therapy mode is achieved through an external therapy patch connected to an electrode interface pre-installed at the end of the temples.

[0018] By adopting the above technical solution, the temple therapy mode uses flexible TENS electrodes integrated into the temples of the glasses. This allows for direct electrical stimulation of the temple area without additional connections, making it suitable for relieving eye fatigue, headaches, and promoting sleep. The flexible material ensures comfort and a snug fit even during extended wear. The full-body therapy mode utilizes standard electrode interfaces pre-installed at the temples, allowing for the connection of external therapy patches to other parts of the body (such as the shoulders, neck, waist, and limbs), achieving multi-functionality. This design enables the smart glasses to retain their everyday audio functions while functioning as a portable head therapy device independently, or as a full-body therapy device, greatly expanding the product's application scenarios and target audience, and avoiding the redundant investment of purchasing separate therapy devices for different body parts.

[0019] In summary, this application offers the following beneficial technical effects: Through a dual-zone electrical isolation architecture, interference between Bluetooth audio and TENS high-voltage pulses is completely eliminated, preventing popping sounds, noise, and system crashes, significantly improving sound quality and system stability; the use of a three-button multiplexing control logic allows for complete power on / off, pairing, volume adjustment, intensity adjustment, and mode switching without relying on an app, making operation extremely simple and user-friendly for middle-aged and elderly users and non-smartphone users; a triple safety mechanism is constructed, including charging lockout, 15-minute automatic timer, load detection, and no-load protection, effectively preventing leakage, overstimulation, and no-load electric shock risks; furthermore, it achieves the integrated fusion of Bluetooth headset, temple therapy device, and full-body therapy device, and can be extended to multiple body parts via external electrodes, truly achieving "one device for multiple uses," combining portability, safety, and wide applicability.

Detailed Implementation

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1, referring to Figures 1-3 A method for integrated control of smart glasses combining Bluetooth audio and TENS electrical stimulation is disclosed. The smart glasses include a frame 1 made of lightweight materials and temples 2. The temples 2 integrate a Bluetooth audio module, a high-voltage TENS module, isolation devices, three physical buttons, a lithium battery, and a Type-C interface. Flexible TENS electrodes are provided at the temples, and electrode interfaces are provided at the ends of the temples 2 for connecting to external full-body therapy patches. The usage steps are as follows: S1. The internal circuit of the smart glasses is divided into a Bluetooth audio low-voltage area and a TENS high-voltage pulse area. Electrical isolation and ground isolation are achieved between the two areas through isolation devices to avoid interference of high-voltage pulses on the audio signal. S2. Three physical buttons are installed on the temple 2 to achieve button reuse control without the need for an app, wherein: The first button is used to increase the volume or massage intensity. The second button is used to decrease the volume or reduce the massage intensity. The third button is used for power on / off, Bluetooth pairing, mode switching, and switching between temple therapy and full-body therapy modes. S3. When the charging interface is detected to be connected to a charging power source, the output of the TENS high-voltage module is automatically locked, and the physiotherapy function is prohibited from being started. S4. When the TENS function is enabled, the timer will start automatically and stop the high voltage output automatically after the preset time is reached. S5. The load detection circuit set at the TENS output terminal detects the electrode connection status in real time. If no load is detected or the load is disconnected, the high voltage output is automatically blocked.

[0023] This application first eliminates interference between Bluetooth audio and TENS high-voltage pulses through electrical isolation, ensuring stable sound quality without popping. Secondly, three physical buttons control all functions, including volume, intensity, power on / off, and mode switching, eliminating the need for an app and simplifying operation. Simultaneously, the high-voltage output is automatically locked during charging to prevent leakage risks; the timer automatically stops after 15 minutes of therapy to avoid overstimulation; and the output is automatically blocked when no electrodes are connected to prevent electric shock under no-load conditions. Overall, this method achieves interference-free coexistence of audio and therapy functions, along with convenient one-button control, while ensuring safety.

[0024] In this embodiment, the isolation device is an optocoupler isolator or a digital isolation chip. The operating voltage of the Bluetooth audio low-voltage region is 3.7V, and the output voltage of the TENS high-voltage pulse region is adjustable from 0-60V.

[0025] Optical isolators use optical signals to transmit on / off control, while digital isolation chips achieve high and low voltage separation through chip-level capacitors or magnetic couplings. Both can completely cut off the ground loop and electrical coupling path between the Bluetooth low voltage area (3.7V) and the TENS high voltage area (0-60V).

[0026] In this embodiment, the three physical buttons are multiplexed for control: A short press of the first button increases the volume, while a long press increases the massage intensity. A short press of the second button decreases the volume, while a long press decreases the massage intensity. Press and hold the third button for 3 seconds to turn the device on or off, press it briefly to pair via Bluetooth or switch modes, and double-click to switch between temple therapy mode and full-body therapy mode.

[0027] By using a short press to adjust volume and a long press to adjust intensity, the function of the same button in different modes is naturally distinguished, allowing users to operate intuitively based on the duration of the press without any learning. The third button uses a 3-second long press as a threshold to prevent accidental touches when turning the device on or off. A short press enables Bluetooth pairing and switching between audio / therapy modes, while a double press quickly switches between temple therapy and full-body therapy modes. This allows the three buttons to fully cover five core operations—power on / off, pairing, volume adjustment, intensity adjustment, and mode switching—without increasing the number of buttons. This logic completely eliminates reliance on a mobile app, supports blind operation, and is especially suitable for sports, the elderly, or those with visual impairments. It also avoids the impact of excessive buttons due to function stacking on the temples and wearing comfort.

[0028] In this embodiment, the temple therapy mode is achieved by a flexible TENS electrode set at the temple of the smart glasses, and the whole body therapy mode is achieved by connecting a therapy patch to an electrode interface reserved at the end of the temple 2.

[0029] In Example 2, this application indicates that the device defaults to audio mode upon power-on. Volume is adjusted by shorting button 1 / button 2; Bluetooth pairing is switched by shorting button 3; after entering therapy mode, buttons 1 and 2 adjust intensity, and button 3 switches between temple / full-body therapy modes. The TENS is automatically turned off during charging, and output is disabled when no load is connected.

[0030] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
