Description

Technical Field

[0001] This utility model relates to the field of pendant technology, and in particular to a smart necklace pendant. Background Technology

[0002] In recent years, the development of wearable electronic devices has expanded from simple data recording to providing physical feedback and human-computer interaction. An emerging technological direction is to develop portable devices that can provide users with multi-dimensional, multi-sensory physical signal outputs, in order to establish a more direct and immersive human-computer interaction experience.

[0003] However, existing technologies still have many limitations in achieving this goal. Many devices that provide rhythmic signals rely on smartphone application interfaces or the device's built-in display for guidance. This visual interface-based information delivery method not only requires users to maintain continuous visual attention, but its physical form is often bulky due to the screen or complex structure, making it inconvenient for prolonged continuous wear. Even if some devices use light-emitting diodes (LEDs) as visual cues, their function is mostly limited to simple status indications. Technically, there are few designs that use dynamic light effects as the core information feedback channel and rhythmically synchronize them with other functional modules of the device, failing to fully utilize visual signals as a rich dimension of physical feedback.

[0004] In terms of audio output, most portable devices currently rely on traditional external speakers to play sound. The technical drawback of this approach is that sound diffuses into the surrounding environment, making directional or private transmission impossible. This limits the device's use in quiet public spaces or situations where personal privacy is paramount.

[0005] Furthermore, in terms of physical interaction mechanisms, existing devices are mostly limited to buttons or touchscreens, lacking an integrated structure that can be controlled by internal programs, actively change its physical form, and dynamically interact with the user through touch. Although there are some independent accessories on the market that allow users to perform physical operations, they are usually single-function and cannot be linked with electronic systems, resulting in a significant deficiency in the depth and richness of physical interaction. Summary of the Invention

[0006] To address the aforementioned technical problems, this utility model provides an intelligent necklace pendant, aiming to improve upon the shortcomings of existing portable electronic devices, such as limited physical feedback, insufficient interactive dimensions, and difficulty in providing immersive multi-sensory collaborative guidance while ensuring privacy.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A smart necklace pendant includes a housing, a vibration motor installed inside the housing, a pad connected to the drive end of the vibration motor, a silicone pad installed on the inner wall of a through hole at the bottom of the housing, the pad contacting the surface of the silicone pad, a microcontroller installed inside the housing, the microcontroller electrically connected to the vibration motor, a soothing mechanism penetrating the outer wall of the housing, and a fragrance component installed at the top of the housing.

[0009] Furthermore, the fragrance component includes an anti-overflow base, which is installed on the upper surface of the housing. The upper surface of the housing is provided with a dustproof glass cover, and the dustproof glass cover penetrates the upper surface of the anti-overflow base, with several holes through the surface. A piezoelectric ceramic atomizing plate is installed on the inner bottom wall of the anti-overflow base, and a conduit is provided through the side wall of the anti-overflow base. A drip head is installed at one end of the conduit, and a water pump is connected to the other end. The water pump input end is connected to a liquid storage chamber. The drip head is externally positioned above the piezoelectric ceramic atomizing plate, and the liquid storage chamber is externally installed inside the housing. A cover is threaded through the outer wall of the housing at the liquid inlet.

[0010] Furthermore, the relief mechanism includes a drive assembly and an mounting sleeve. The drive assembly controls the automatic removal of the rotating ball from the mounting sleeve, which extends through the outer wall of the housing. A piston slides on the inner wall of the mounting sleeve, and when the piston rotates to the outer wall, a rotating ball is present. When the outer wall of the housing rotates, a cover plate is present. The diameter of the cover plate is the same as the inner diameter of the mounting sleeve, and it is used to seal the outlet of the mounting sleeve when the rotating ball is inside the mounting sleeve.

[0011] Furthermore, the drive assembly includes an air pump, which is installed inside the housing. One end of the air pump output is connected to a hose, and the other end is connected to a mounting sleeve.

[0012] Furthermore, one end of a spring is installed on the inner wall of the mounting sleeve, and the other end is connected to the outer wall of the piston. The end of the hose is located in the area where the spring is located inside the mounting sleeve.

[0013] Furthermore, multiple light strips are provided on the surface of the housing, and the exterior is set inside the dustproof glass cover and the housing.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects:

[0015] This invention utilizes a vibration motor precisely controlled by a microcontroller to output rhythmic physical vibrations, directly guiding the user's breathing rhythm through touch. This design transforms the abstract "inhale-hold breath-exhale" command into a perceptible physical signal. Compared to existing technologies that rely on visual or auditory cues, this solution provides a more intuitive and immersive guidance mode, effectively solving the technical problems of user inattention and poor guidance effect, and significantly improving the effectiveness of breathing regulation. By innovatively combining an LED strip with a physical feedback system, the color, brightness, and frequency of the LED strip's light are controlled programmatically to synchronize with a preset vibration rhythm. This multi-sensory feedback design, linking light and touch, creates an immersive adjustment atmosphere for the user. It fills the gap in existing wearable devices' use of light effects for auxiliary adjustment and transforms the design concept of using visual signals for state guidance into a concrete and feasible technical solution, thereby enriching the dimensions and experience of physical feedback.

[0016] By incorporating a miniature bone conduction vibrator that directly contacts the user's skin, the device achieves private audio signal transmission. This structure does not rely on air as a propagation medium; instead, it transmits white noise or specific audio frequencies directly through the skull to the auditory nerve. This ensures clear audio reception for the user while avoiding interference with the surrounding environment. Compared to traditional external speakers, this solution significantly expands the device's usability and solves the problem of limited use in public or quiet environments. An air pump-driven, automatically extending rotating bead-type soothing mechanism is designed on the exterior of the casing. This structure provides the user with an actively interactive physical contact point. Users can operate the device through sliding, pressing, or rotating actions to obtain clear tactile feedback. This design guides the user's unconscious movements towards a safe interactive behavior, providing not only a novel form of tactile feedback but also solving the technical problems of traditional wearable devices' limited functionality and lack of physical interaction.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 -Appendix Figure 6 An embodiment of this utility model includes a housing 1, in which a vibration motor 20 is installed. The driving end of the vibration motor 20 is connected to a pad 21. A silicone pad 19 is installed on the inner wall of the bottom through hole of the housing 1, and the pad 21 is in contact with the surface of the silicone pad 19. A microcontroller 9 is provided inside the housing 1, and the microcontroller 9 is electrically connected to the vibration motor 20. A soothing mechanism is provided through the outer wall of the housing 1, and a fragrance component is provided on the top of the housing 1.

[0028] Specifically, when a user wears this necklace pendant, the pendant will hang naturally and fit snugly against the user's chest. Upon system startup, the built-in microcontroller 9 receives the startup signal, and its main control program begins running.

[0029] According to a preset program or user instructions, the microcontroller 9 sends a periodic pulse signal with a specific rhythm to the vibration motor 20. The vibration motor 20 (which can be an eccentric wheel motor) receives the signal and begins to operate, transmitting the vibration generated by its rotation through the pad 21 fixed to it. This vibration is then transmitted to the user's chest skin via the elastic silicone pad 19. By precisely controlling the frequency and duty cycle of the drive signal, the vibration can simulate a specific rhythmic pattern, such as a "vibrate for 4 seconds—pause for 7 seconds—vibrate again for 8 seconds" pattern, thereby guiding the user to adjust their breathing rhythm through tactile feedback. Simultaneously, this vibration can also serve as a cue signal, for example, providing feedback through a specific vibration pattern when the user's physiological indicators deviate from a preset baseline. The application of the silicone pad 19 not only enhances wearing comfort but also effectively cushions and smooths the vibration, making its transmission gentler and avoiding harsh physical impact.

[0030] Under the control of the microcontroller 9, the soothing mechanism on the outer wall of the housing 1, in conjunction with driving components such as the air pump 11, enables the automatic extension or retraction of the rotating bead 17. Users can obtain clear tactile feedback by actively sliding or rotating the bead when needed. This interactive behavior can be considered a user-initiated physical operation, and the structure can be designed with an automatic reset function for easy reuse.

[0031] The fragrance component at the top is used to efficiently atomize and directionally release specific liquids, forming an aerosol that can be perceived by the user, thereby providing a physical output based on the sense of smell.

[0032] In summary, this embodiment uses a single-chip microcomputer 9 (model STC microcomputer) to coordinate the collaborative work of multiple modules such as vibration guidance, tactile interaction, and aerosol release, ultimately realizing a multi-sensory, composite physical interaction function.

[0033] Reference Figure 4 The fragrance component includes an anti-overflow seat 3, which is installed on the upper surface of the housing 1. A dustproof glass cover 2 is provided on the upper surface of the housing 1. The dustproof glass cover 2 is inserted through the upper surface of the anti-overflow seat 3 and has several holes. A piezoelectric ceramic atomizing plate 4 is installed on the inner bottom wall of the anti-overflow seat 3. A conduit 5 is inserted through the side wall of the anti-overflow seat 3. A drip head 6 is installed at one end of the conduit 5 and a water pump 7 is connected to the other end. The input end of the water pump 7 is connected to a liquid storage tank 8. The drip head 6 is externally positioned above the piezoelectric ceramic atomizing plate 4. The liquid storage tank 8 is externally installed inside the housing 1, and a cover 14 is threaded through the outer wall of the housing 1 at the liquid inlet.

[0034] Specifically, when the user presses, touches, or the system triggers the function according to preset conditions, the microcontroller 9 inside the housing 1, which serves as the control center, will receive a start signal.

[0035] The microcontroller 9 issues control commands to drive the water pump 7. The water pump 7 draws pre-stored liquid from the storage tank 8 and delivers it to the drip head 6 through the conduit 5.

[0036] The dropper head 6 precisely injects liquid in droplet form onto the surface of the piezoelectric ceramic atomizing plate 4 below. Simultaneously, the microcontroller 9 applies a high-frequency electrical signal to the piezoelectric ceramic atomizing plate 4, causing it to vibrate at high frequency. This vibration breaks down the liquid into micron or nanometer-sized particles, forming an aerosol.

[0037] The generated aerosol accumulates within the interior space of the spill containment base 3 and is uniformly released outwards through multiple micropores at its top. The mating structure of the spill containment base 3 and the dustproof glass cover 2 ensures the directional release of the aerosol and reduces its diffusion into non-target areas. Simultaneously, the transparent dustproof glass cover 2 allows users to easily observe the operating status of the components. This application can convert specific liquids into gases on demand and release them directionally, providing users with a physical output based on their olfactory senses. The design of the spill containment base and glass cover ensures the directionality and cleanliness of the release.

[0038] Through the aforementioned collaborative operation, this structure enables the conversion of liquid within the chamber into a controllable aerosol and its release to a designated area. When liquid replenishment or replacement is required, the user can operate the system by unscrewing the hatch cover 14 on the outer wall of the shell 1, ensuring ease of use.

[0039] Reference Figure 4 -Appendix Figure 7 The soothing mechanism includes a drive assembly and a mounting sleeve 13. The drive assembly is used to control the automatic removal of the rotating ball 17 from the mounting sleeve 13, which penetrates the outer wall of the housing 1.

[0040] A piston 16 slides on the inner wall of the mounting sleeve 13. A rotating ball 17 rotates on the outer wall of the piston 16, and a cover plate 18 rotates on the outer wall of the housing 1. The diameter of the cover plate 18 is the same as the inner diameter of the mounting sleeve 13. When the rotating ball 17 is inside the mounting sleeve 13, it is used to seal the outlet of the mounting sleeve 13.

[0041] The drive assembly includes an air pump 11, which is installed inside the housing 1. The output end of the air pump 11 is connected to one end of a hose 12, and the other end of the hose is connected to a mounting sleeve 13.

[0042] One end of a spring 15 is installed on the inner wall of the mounting sleeve 13, and the other end is connected to the outer wall of the piston 16. The end of the hose 12 is located in the area where the spring 15 is located inside the mounting sleeve 13.

[0043] Specifically, when the user wears the necklace pendant and activates the device, the microcontroller 9 sends a working signal to the air pump 11 in the drive assembly according to preset instructions or user operation. The air pump 11 starts, pumping gas into the internal space of the mounting sleeve 13 through the hose 12. The continuous airflow creates pressure inside the sleeve, which acts on the piston 16, pushing it outward against the elastic force of the spring 15. As the piston 16 moves, the connected rotating bead 17 is pushed out synchronously, eventually opening the cover plate 18 and partially extending outside the mounting sleeve 13. At this time, the user can perform physical operations by sliding or rotating the extended rotating bead 17. During this process, the spring 15 is compressed, storing elastic potential energy.

[0044] When the microcontroller 9 instructs the air pump 11 to stop working, the air pressure inside the mounting sleeve 13 is released. The previously compressed spring 15 releases its stored elastic potential energy, generating a rebound force that pushes the piston 16 back into the sleeve. The piston 16 then retracts the ball bearing 17 into the mounting sleeve 13. This extension and retraction process is completed automatically by the system without manual intervention from the user.

[0045] Once the bead 17 has fully retracted, the cover plate 18 can be reset to seal the outlet of the mounting sleeve 13, which helps prevent foreign objects from entering the mechanism and maintains the integrity of the pendant's overall appearance.

[0046] Under the unified control of the microcontroller 9, this haptic interaction mechanism can work in conjunction with other feedback modules (such as vibration, light, etc.) to provide users with a composite physical interaction experience.

[0047] Reference Figure 1 -Appendix Figure 2 and attached Figure 4 Multiple light strips 22 are provided on the surface of the housing 1, and the exterior is set inside the dustproof glass cover 2 and the housing 1.

[0048] Specifically, the microcontroller 9 inside the housing 1 will activate the lighting components according to its control program.

[0049] The microcontroller 9 outputs control signals to each LED strip 22, such as pulse width modulation (PWM) signals to adjust the brightness, or address control signals to independently control one or more LED units.

[0050] Upon receiving the signal, the LED strip 22 is illuminated. Through precise control by the microcontroller 9, the LED strip 22 can achieve various lighting effects, such as gradual color changes, periodic brightness variations creating a breathing light effect, flashing at a specific frequency, or continuous illumination. The LED strip 22 can emit different colors of light, such as blue, green, or warm white.

[0051] The light effect changes of the light strip 22 (such as change frequency, color switching, etc.) can be synchronized with the output rhythm of other components such as the vibration module. For example, the brightness change period of the light can be set to be exactly the same as the vibration period of the vibration module, thereby realizing the coordinated output of multi-sensory physical signals.

[0052] The dustproof glass cover 2 is designed to protect the internal light strip 22 from external physical damage or contamination. On the other hand, its transparent or semi-transparent material can soften and diffuse the light emitted by the light strip, making the final light effect more uniform and soft, and avoiding the glare that may be caused by direct illumination from an exposed light source.

[0053] In addition, the overall brightness and color transition parameters of the light strip 22 can be set by the user in the accompanying application, or automatically adjusted by the system according to the preset algorithm to adapt to different ambient lighting conditions or functional modes.

[0054] Reference Figure 3 -Appendix Figure 5 The bottom of the housing 1 is equipped with a miniature bone conduction vibrator 10, which is electrically connected to the microcontroller 9. It is used to transmit soothing audio to the user through bone conduction that fits against the skin, creating a private and comforting auditory experience.

[0055] Specifically, when a user wears this device, the housing 1 naturally fits against the chest or collarbone area, and the miniature bone conduction vibrator 10 embedded in the bottom of the housing 1 makes close contact with the user's skin. After the device is turned on, the microcontroller 9 will retrieve a preset digital audio signal (such as white noise, sound waves of a specific frequency, etc.) from its internal storage unit (such as an audio chip). This digital signal is then converted into an analog electrical signal that can drive the vibrator through a digital-to-analog converter circuit.

[0056] A drive signal is sent to the miniature bone conduction oscillator 10, causing it to generate precise mechanical vibrations corresponding to the audio signal. Since the oscillator is in close contact with the user's body (such as bone tissues like the sternum and clavicle) through the housing, these mechanical vibrations transmit the sound signal directly to the user's auditory nerve via bone conduction.

[0057] This structure enables audio transmission that does not rely on air as a propagation medium. Compared to traditional speakers, its main advantage is that sound does not diffuse into the external environment, thus providing users with a clear and highly private way to receive auditory information. This feature effectively solves the problem of potential interference to others when using audio functions in public or quiet environments. Furthermore, the frequency characteristics of the output audio signal (e.g., emphasizing the low-frequency range) can be preset according to design requirements. This component can work in conjunction with other modules such as lighting and vibration to form a multi-dimensional physical feedback system.

[0058] The working principle of this utility model is as follows: After the user wears the necklace pendant, the pendant naturally fits against the chest, ensuring that the miniature bone conduction vibrator 10 is in full contact with the skin. The user can activate the internal circuit system by pressing the housing 1 or turning on the control switch. The internal microcontroller 9 starts the main control program and enters the standby wake-up state.

[0059] After the program starts, the microcontroller 9 first sends a command to the vibration component to activate the vibration motor 20. By outputting a pulse drive signal with a specific rhythm, the microcontroller 9 controls the vibration motor 20 to generate intermittent vibration, such as simulating a cycle of "vibrate for 4 seconds - pause for 7 seconds - vibrate again for 8 seconds". This vibration is directly transmitted to the user through the silicone pad 19 at the bottom of the housing 1 to provide a tactile rhythm signal that the user can perceive.

[0060] Synchronized with the vibration rhythm, the lighting module is triggered. The microcontroller 9 controls the light strip 22 to display specific lighting effects, such as automatically switching to different colors like blue, green, and warm white according to the program, or displaying periodic changes in light brightness. The rhythm of the light changes can be kept consistent with the output rhythm of the vibration module, achieving coordinated output of multi-sensory physical signals.

[0061] When the system receives the activation command for the aerosol release function, the microcontroller 9 drives the micro water pump 7 to draw liquid from the liquid storage tank 8 and deliver it to the surface of the piezoelectric ceramic atomizing plate 4 through the conduit 5. Subsequently, the microcontroller 9 applies a high-frequency electrical signal to the piezoelectric ceramic atomizing plate 4 to activate it, atomizing the contacted liquid into micron or nano-sized particles, and releasing them directionally into the external environment through the micropores on the top of the spill containment seat 3.

[0062] Simultaneously, the bone conduction audio module can be activated. The microcontroller 9 calls upon internally stored audio files (such as white noise, sound waves of specific frequencies, etc.) and controls the drive circuit to send the corresponding audio signal to the miniature bone conduction vibrator 10. The mechanical vibration generated by the miniature bone conduction vibrator 10 transmits the audio signal directly to the user via bone conduction through contact with the skin. This process does not produce external sound, ensuring the privacy of information reception.

[0063] Under program control, the air pump 11 can be started, and the gas it outputs enters the mounting sleeve 13 through the hose 12, generating a thrust on the piston 16. This thrust overcomes the elastic force of the spring 15, pushing the piston 16 and the connected rotating ball 17 outward until the rotating ball 17 partially extends out of the mounting sleeve 13.

[0064] The extended ball bearing 17 provides the user with an interactive component that allows for physical operations such as rotation or sliding. When the air pump 11 stops working, the restoring force of the spring 15 will cause the piston 16 and the ball bearing 17 to automatically return to their initial positions.
