Thepreset audio includes white noise, children's parents' voices and so on.

[0067] Moreover, when the mobile phone is connected with the sleep aid device byBluetooth, the base 200 is equivalent to a Bluetooth speaker, and the audio in the mobilephone can be played through the mobile phone APP or required audio is recorded on themobile phone APP and played, and the timbre of the children's parents can be recordedthrough the mobile phone APP, and then the audio that comforts the children can be playedthrough AI combined with the timbre of the children's parents.

[0068] In other embodiments (not shown), the lamp body 100 and audio soothingresponses are activated through AI recognition of a child’s crying, turning over, bodymovements, thermal sensations, and other states.

[0069] In other embodiments (not shown), a model is trained via AI or big data toestablish an "optimal sleep rhythm pattern" based on age groups, and dynamic adjustment isperformed through a combination of lighting and audio.

[0070] In other embodiments (not shown), a mobile app can simultaneously connectmultiple lamp bodies 100 and bases 200, suitable for use in multi-child households.

[0071] In other embodiments (not shown), in the child sleep assistance device, sleepprogram content is pre-downloaded and locally stored via an app, executed independently bythe device to avoid program interruption or lag due to network outages. The use of the sleepprogram includes the following steps: setting a sleep program via a client mobile device,including audio, lighting, and control instructions; downloading the sleep program contentwirelessly to the local storage module of the sleep aid device for children; at user-set timepoints or when trigger conditions are met, reading the program content from local storage bythe device’s local processor; executing tasks such as audio playback and lighting control in apreset sequence; the execution process does not rely on real-time communication with as[0er0v7e2r].According to the above, the WIFI module 302 is also installed on the secondcircuit board 207, and the first antenna 303 is installed on the WIFI module 302. The secondcircuit board 207 is connected with the USB interface 310 through wires, and the USBinterface 310 penetrates the outer surface of the shell 201. A plurality of control buttons 203electrically connected with the second circuit board 207 are installed on the outer surface ofthe shell 201, and the foot pad 204 for supporting the base 200 is installed at the bottom of theshell 201.

[0075] The control button 203 is a mechanical switch or a touch switch, so the user caneasily control the base 200 through the physical operation of the mechanical switch or thetouch of the touch switch, and a plurality of control buttons 203 are arranged, so that eachcontrol button 203 has different functions, such as turning on or off the sleep aid device,unlocking the sleep aid device, and adjusting the light and volume. And when the base 200and the lamp body 100 are successfully connected, the function of this control button 203 isextended due to the conduction structure between them, which can not only control variousfunctions of the base 200, but also directly control the lamp body 100. This design not onlyimproves the user experience, but also increases the intelligence of the equipment.

[0076] In other embodiments (not shown), a small projection module (e.g., a micro DLPor LCoS projection engine) is added inside the lamp body 100, installed at the top or side ofthe inner surface of the lampshade 101. This module is electrically connected to the firstcircuit board 103. The memory on the first circuit board 103 (or cloud storage connected viathe WIFI module 302) stores various static starry sky patterns, dynamic story scenes (e.g.,slowly moving clouds, stars, story character silhouettes), or soothing dynamic light effects(e.g., slowly changing water ripples). Users can select projection content, adjust projectionbrightness / focus (if auto-focus is supported), and set projection timers via a mobile app. Thecontrol button 203 can also be preset for projection on / off or mode switching. Projectioncontent can synchronize with audio stories played by the base 200, such as projectingunderwater light effects when playing ocean stories, enhancing immersion.

[0077] In other embodiments (not shown), the base 200 is internally provided with a ringarray of 4 sets of electromagnets (replacing the second magnet 208), connected to a dynamicbalance controller (integrated into the second circuit board 207). The bottom of the lamp body100 is embedded with a permanent magnet array (replacing the first magnet 106), where thepolarity distribution of the permanent magnets corresponds to the electromagnets to form arepulsive force field. The mating surface 209 of the base 200 incorporates a Hall sensor arrayto monitor the suspension height and tilt angle of the lamp body 100 in real time.

[0078] In other embodiments (not shown), the lampshade 101 includes a shaped shell, alight-guiding layer, and an embedded identification module. Specifically: the shaped shelltakes the form of cartoon characters, animals, or geometric patterns; the light-guiding layer ismade of light-diffusing material to guide the light emitted by the internal light source forspecific visual effects; the identification module transmits character ID information to thedevice processor when the lampshade 101 is installed on the device; upon receiving thecharacter ID, the processor drives the light color, brightness, rhythm, and sound effects tosynchronize with the character theme based on preset data; the lampshade 101 is connected tothe lamp body 100 via snap-fit, magnetic, or twist-lock mechanisms, allowing users to freelyreplace it; the structure supports multiple lampshade 101 designs for universal use on thesame base 200 platform.

[0079] Example 2:

[0080] A sleep aid device for children includes a lamp body 100 and a base 200, whereinthe lamp body 100 and the base 200 are detachably connected; an audio playing component isarranged in the base 200 for playing preset audio; a first circuit board 103 and a second circuitboard 207 are respectively arranged in the lamp body 100 and the base 200; a single chipmicrocomputer 301 and a Bluetooth control module for wireless connection WIFI a mobilephone are installed on the first circuit board 103 and the second circuit board 207.

[0081] The difference between Example 2 and Example 1 is that:

[0082] The lamp body 100 and the base 200 can be connected by detachable connectionmodes such as clamping, threaded connection and the like. The first circuit board 103 isfurther provided with a voice control module 305 and a sensor lamp 306. The voice controlmodule 305 is used for monitoring the ambient volume, and the sensor lamp 306 isautomatically turned on when the ambient volume exceeds a preset value. The first circuitboard 103 and the second circuit board 207 are both provided with a second antenna 307 fordata transmission between the first circuit board 103, the second circuit board 207 and themobile phone.

[0083] The voice control module 305 can monitor the ambient volume, and can monitorthe ambient volume in real time and compare it with the preset sound decibel value. Once themonitored decibel value exceeds the preset value, the voice control module 305 willautomatically start the sensor lamp 306 to provide users with real-time lighting services, andat the same time, the single chip microcomputer 301 will automatically play the preset audioor adjust the light of the lamp body 100. This method not only improves the intelligent levelof the equipment, but also brings users a more convenient experience.

[0084] By setting the second antenna 307, when the mobile phone is connected with thesecond circuit board 207 through the wireless network, the first circuit board 103 and thesecond circuit board 207 can be wirelessly connected through the two second antennas 307,thereby realizing wireless data transmission among the base 200, the lamp body 100 and themobile phone. This method not only expands the functional scope of the equipment, but alsoprovides users with more diverse usage scenarios.

[0085] In other embodiments (not shown), the lamp body 100 is designed as a compact,lightweight standalone unit, with shapes such as spherical or small animal figures. Its shell(similar to the lampshade 101) is made of soft silicone or fabric and integrates a hanging holeor detachable clip / strap.

[0086] Inside the compact lamp body 100, the following components are highly integrated:the first circuit board 103 (including a single chip microcomputer 301, a Bluetooth controlmodule 309, and a small-capacity power module 105 such as a button cell or small lithiumbattery); a miniature light-emitting element 107 (e.g., single or multiple small LEDs);optionally, a miniature speaker 206 (for basic audio playback functions like white noise orsimple melodies) or only the voice control module 305 (for detecting cries to trigger lightc[0h0a8n7g]es).This portable lamp body 100 can operate entirely without relying on the base 200.It can also be clipped to a crib railing, hung by the bedside, held or worn by children as asoothing toy (e.g., around the neck or wrist, ensuring absolute safety), or carried during travel.

[0088] In other embodiments (not shown), this sleep aid device for children can also beused in outdoor tent scenarios. The outdoor tent is integrated with a blackout tent, rhythmiclighting module, smart sleep device, and audio content control system into a unifiedimmersive sleep aid system for children, providing synergistic effects of rhythm guidance,automatic soothing, environmental isolation, and content companionship.

[0089] The sleep aid system includes: a blackout tent body, structurally made of enclosedflexible light-blocking material, equipped with ventilation windows and a main deviceplacement area; a rhythmic lighting module, built into the top or sidewalls of the tent,supporting brightness, color temperature, and gradient control, with lighting parameterssynchronized to a rhythm model; a smart sleep device host, which can be fixed to the tent viamagnetic or slot attachment, featuring functions such as audio playback, rhythm triggercontrol, and AI content output; an audio output module, playing AI stories, parental voices, orrhythmic sound effects in sync with the lighting; an App control platform, allowing users toset rhythm plans, story content, and light-effect linkage modes via smartphone; and anenvironmental detection module, which senses children’s nighttime movements, sounds, orchanges in temperature / humidity, automatically triggering rhythm reset and soothing content.Compared to traditional tents or standalone sleep devices, it provides a fully enclosedimmersive rhythmic sleep space; synchronized light and audio output creates a completerhythmic beat guidance process; all modules can be linked and controlled via the App tomatch the baby’s sleep-wake rhythm; the system supports parental voice story uploads and AIsynthesis to enhance emotional companionship; the system can automatically respond to ababy’s nighttime awakenings, improving nighttime soothing capabilities.

[0090] Example 3:

[0091] The difference between Embodiment 3 and Embodiment 2 is that there is at leastone base 200 and one or more lamp bodies 100. The base 200 is detachably connected WIFIone or more lamp bodies 100, and an audio playing component is arranged in the base 200 forplaying preset audio. The first circuit board 103 and the second circuit board 207 arerespectively arranged in the lamp bodies 100 and the base 200, and the first circuit board 103and the second circuit board 207 are both equipped with a single chip microcomputer 301, aBluetooth control module 309 for wireless connection with a mobile phone, and a WIFImodule 302 for connection with a server.

[0092] The Bluetooth control module 309 of the base 200 can be matched and connectedwith the mobile phone, while a plurality of lamp bodies 100 can be matched and connectedwith the base 200 through the Bluetooth control module 309, and a plurality of lamp bodies100 are also matched and connected with each other through the Bluetooth control module309. Therefore, in this way, when the mobile phone is connected with the base 200, all thelamp bodies 100 can be controlled.

[0093] Moreover, in this embodiment, a plurality of lamp bodies 100 can be detachablyattached to the base 200, and at the same time, a plurality of lamp bodies 100 can also bedetached from the base 200 and placed at required positions respectively.

[0094] Moreover, in this embodiment (not shown in the attached drawings), the layout ofthe audio playing component is not limited to the installation inside the base 200. In fact, theaudio playing component can also be installed in the lamp body 100 by the technical means ofExample 1, thus endowing the lamp body 100 with the function of audio playing in additionto lighting.

[0095] Therefore, in this way, the lamp body 100 with the audio playing component isplaced in the required place, so that a more stereoscopic sound effect and an all-round lightingenvironment can be achieved, and sound and light can be prevented from emitting from onepoint, thus making the sleeping environment of children more comfortable.

[0096] Moreover, in this embodiment, the color and shape of each lamp body 100 aredifferent, so in this way, the styles of the lamp bodies 100 can be replaced according to thechildren's favorite, so as to be combined into sleep aid devices with different styles, and theapplicability of the sleep AIDS is improved.

[0097] In other embodiments (not shown), the lamp body 100 can mimic sunrise andsunset movements. The interior of the lamp body 100 contains multiple independentlycontrollable light sources, with control methods including； dividing the lampshade 101vertically into at least two light-zone regions; during preset wake-up or sleep periods,sequentially controlling the light sources in different zones to turn on or off in a gradientr[h0y0t9h8m].The light-zone control process includes color gradients, brightnessincrease / decrease, or color temperature transitions; this process simulates the light changes ofsunrise or sunset in natural environments and supports both local control and remote Appc[0o0n9fi9g]uratioInn.other embodiments (not shown), the sleep aid device includes a main unitstructure: the main body integrates a speaker and a lamp, supporting rhythmic lightadjustment and audio playback; the top features a doll interface area, including magnetic slots,conductive contact areas, optical recognition windows, etc. The doll structure includes a basecomponent that is physically engaged with the top structure of the main unit; each pose (e.g.,lying down, sitting, reading, raising hands, etc.) serves as an identity marker; optionalintegrated recognition elements (e.g., magnetic polarity, mechanical structure coding, opticalmarkers, chip contacts, etc.); the doll can also be designed as a non-detachable fixed structure,molded integrally with the lamp body 100. Recognition and control module: the main chipdetects signal changes upon doll insertion; based on recognition data, it matches thecorresponding rhythmic scene content (e.g., playing white noise + orange light at night, orstories + natural light for a reading doll); such content can be preset via an app orautomatically downloaded; the control output module synchronizes gradual light changes +audio playback. The doll and the lamp body can be connected via magnetic attraction, plug-insockets, or snap-fit mechanisms; recognition methods include but are not limited to: bottomconductive sheet closed circuit, resistance recognition, optical coding recognition, pose imagerecognition, mechanical slot detection, etc.; the doll’s head, expression, or posture can serveas recognition factors to trigger different rhythms / lighting / story content; a timing mechanism(e.g., auto shut-off) or character voice synthesis (e.g., AI mimicking a character’s tone forstorytelling) can be added; the doll may be also integrated with content storage chips (e.g.,EEPROM) for the main unit to read and play. This achieves triple synchronization of speaker+ lighting + replaceable dolls; without NFC or wireless sensing, the recognition method issafer and more stable; it provides an emotionally perceptive rhythmic experience (e.g., "lyingpose" represents sleep mode); children can participate in rhythm setting through "placement"actions, enhancing ritual and habit formation; modular content licensing and charactercommercialization expansion are possible, with potential for IP collaboration.

[0100] For instance, a lying doll activates the nighttime sleep aid program, the doll is in aclosed-eye, prone pose, and contact closure is recognized upon placement; the system controlsthe light to shift to orange soft glow + white noise playback; it also records sleep initiationtime for rhythm statistics.

[0101] Additionally, a reading doll triggers a bedtime story mode, with a resistance tagintegrated at its base; upon placement, ID="reading character" is recognized, initiating storyplayback + natural light transition; an automatic voice reminder can prompt, "it’s story time,please prepare to sleep."

[0102] It should be noted that the doll in the structure is part of the design, integrallyformed with the lamp body 100; each device corresponds to different characters, sounds, andrhythm logic, and can be used to create a series of products such as the "Heyaxa CharacterF[0a0m1i0ly3.]"In other embodiments (not shown), the sleep aid device internally includes a userterminal, a rhythm content platform, a sleep companion character system, and arecommendation matching engine. User terminal: collects user sleep behavior data, includingsleep duration, bedtime, nighttime awakenings, user ratings, etc. Rhythm content platform:includes content from creators and platform-produced materials, structured with audio clips,light control parameters, and rhythm step settings. Sleep companion character system: userscan select specific characters to participate in rhythm playback, with characters capable ofcontinuous growth and forming interactive memories with users. Recommendation matchingengine: matches rhythm profiles with content tags to recommend the most suitable rhythmcontent package for the user’s current state. The system supports intelligent revenue sharingfor creators, popularity rankings for rhythm packages, priority recommendations, anddynamic updates to user profiles. This enhances content adaptability and user retention in thesleep assistance system; builds a complete content ecosystem supporting creator contributionsand commercialization; strengthens emotional connections between users and characters,improving continued usage rates; and supports multi-device synchronized playback andrhythm content sharing.

[0104] Example 4:

[0105] The difference between Example 4 and Example 3 lies in that the lamp body 100 isinstalled on the base 200, and an audio playing component is arranged in the base 200 forplaying preset audio, and the first circuit board 103 and the second circuit board 207 arerespectively arranged in the lamp body 100 and the base 200, and a single chipmicrocomputer 301 and a Bluetooth control module 309 for wireless connection with amobile phone are installed on both the first circuit board 103 and the second circuit board 207;the first circuit board 103 is further provided WIFI a voice control module 305 and a sensorlamp 306; the voice control module 305 is used for monitoring the ambient volume, and whenthe ambient volume exceeds a preset value, the single chip microcomputer 301 executes apreset program.

[0106] In this embodiment, the lamp body 100 and the base 200 can be connected in anon-detachable or detachable way, so that the sleep aid device for children also has thefunction of monitoring the ambient volume. When the ambient volume is greater than thepreset value, the children's sleep aid device can automatically execute preset programs, suchas playing preset audio and adjusting the lighting.

[0107] In other embodiments (not shown), additional environmental sensor modules (suchas temperature and humidity sensors, light sensors, PM2.5 sensors) are integrated on thecircuit board (first circuit board 103 or second circuit board 207) of the lamp body 100 orbase 200 (or both). The single chip microcomputer 301 (on the circuit board detectingenvironmental data) executes preset adaptive programs based on sensor data:

[0108] If the temperature is too high / low or humidity is too low, an alert is pushed via themobile app, or smart home devices (supported by WIFI module 302 with relevant protocols)are linked to automatically turn on / off the air conditioner or humidifier. Simultaneously, thelight color temperature can be adjusted (e.g., warmer light in cold conditions) or specificsoothing audio can be played (e.g., rain sounds in dry conditions).

[0109] The light sensor detects ambient light intensity; after a child falls asleep, if theenvironment is too bright, the light automatically dims to a lower level; if the environment isvery dark, the light brightness is maintained or fine-tuned to the most comfortablesleep-inducing level.

[0110] When the PM2.5 sensor detects poor air quality, the app pushes a reminder toparents to ventilate the room.

[0111] Sensor data is uploaded to the cloud server via the WIFI module 302, allowing themobile app to display historical environmental data trends, helping parents understandpatterns in their child’s sleep environment.

[0112] In other embodiments (not shown), an independent sealed chamber is added insidethe base 200, containing: a water tank assembly: a detachable water tank (side-sliding design)with a capacity of 300ml, featuring a transparent water level window; an atomizer: anultrasonic atomizing disc (isolated from the circuit board for moisture protection); a humiditysensor: monitors ambient humidity in real-time (accuracy ±3%RH); a mist outlet: designedwith an independent air duct, located on the side of the shell 201 to avoid interference withthe sound waves of the speaker 206. The second circuit board 207 includes a newly addedhumidification driver module, which adjusts the atomization intensity via the single chipmicrocomputer 301; through a connected mobile app, users can set a target humidity range(40%-70%RH), enabling the device to operate automatically at a constant humidity. When thevoice control module 305 detects a child coughing, it automatically increases the humidity to65%RH; when the ambient humidity falls below 40%RH, the light flashes to remind users toadd water.

[0113] In other embodiments (not shown), a smart sleep device composed of a lamp body100 and a base 200 is installed with a flexible, customizable controllable light strip alongwalls or cribs. The light strip contains a third circuit board, which includes a Bluetooth / WiFidual-mode communication module (interoperable with the main device protocol); multi-zoneindependently addressable RGB LED strings and magnetic patches (compatible with cribrails / wall installation); the smart sleep device and controllable light strip are centrallycontrolled via a mobile app to create an immersive light-accompaniment atmosphere, aidinginfants / children in establishing sleep rhythms through synchronized audio playback. The lightstrip forms a 270° surrounding light field around the crib, eliminating glare stimulation from asingle light source; when the smart sleep device plays lullabies, the light strip graduallybreathes in sync with the sound wave frequency; when the voice control module 305 detectscrying, the light strip automatically switches to a slow-flowing warm yellow light to enhancesoothing immersion.

[0114] Among these, the app interface allows setting the following linkage parameters:rhythm synchronization: light strip’s color transitions according to sleepstages (e.g., dark blue ^ warm yellow ^ lights off); sound-light linkage: lightbrightness / color is dynamically matched with audio playback rhythm (e.g., white noise oceansounds correspond to blue wave light effects); timed scenes: a starry sky projection lighteffect is activated one hour before bedtime; zone control: the light strip is divided into a headsoothing zone / foot monitoring zone for independent dimming.

[0115] Example 5:

Thesesignals are input into a local or cloud-based AI model for analysis to determine whether thechild is in a non-sleeping state. When the AI model identifies that the child is in anon-sleeping state, the device’s control module automatically executes a preset soothingprocedure. The soothing procedure includes at least one of the following: playing soothingaudio, activating gentle light changes, playing parental voice recordings, or simulatingheartbeat sounds. The soothing procedure does not require manual triggering by the user anddoes not rely on real-time server commands.

[0119] In other embodiments (not shown), the first circuit board 103 or the second circuitboard 207 is equipped with a processor and a sensor module. The processor receives sleepschedule parameters set by the user in a mobile application, including wake-up time, bedtime,schedule regularity, and execution cycle. Based on the set parameters, it automaticallygenerates a light change sequence and audio playback program that match the child’scircadian rhythm, including gradual dimming or brightening of light, white noise, or naturalsound playback rhythm. The plan content is downloaded to the local storage module of thesleep aid device. During the preset bedtime period each day, it automatically initiates agradual sleep-inducing routine and activates simulated wake-up lighting before the setwake-up time. The daily execution results are recorded and fed back to the app to evaluate theformation of the sleep rhythm and adjust subsequent rhythm plans. The entire process canoperate without real-time network control and has local execution capability.
