Description

Technical Field

[0001] (Reference to Related Applications) This application is a continuation of U.S. Patent Application No. 18 / 324,059, filed on May 25, 2023, the entire disclosure of which is incorporated herein by reference.

[0002] This disclosure generally relates to the field of sleep improvement devices, and more specifically to a multi-functional sleep training device with sunrise and sunset clock functions.

Background Art

[0003] One way to promote healthy sleep habits is to establish regular pre-bedtime routines using visual and auditory cues generated by sleep training devices such as night lights and white noise machines. However, conventional night lights, alarm clocks, and white noise machines often need to be controlled by manual switches or buttons, and users are forced to take the trouble of such operations in a dimly lit room. In addition, users need to program and set each device individually, prolonging the nighttime routine. Furthermore, such devices often occupy valuable shelf or table space on nightstands and dressers.

[0004] Also, users who are sleep-deprived or distracted may forget to operate or set one or more sleep training devices, and as a result, may have to return to the room where someone is sleeping. In addition, some night lights may not have proper dimming functions and may be too bright visually, or may lack proper volume control and be inconsistent aurally, which may interfere with the user's sleep.

[0005] Therefore, a solution is needed that combines the beneficial functions of multiple sleep training devices to help users establish healthy and regular sleep habits. In addition, such a solution should allow users to remotely control the devices and schedule programs that automatically activate specific visual and auditory cues. Furthermore, such a solution should enable lighting control with dimming functions to reduce light disturbances at night, and sound sealing functions to control sound disturbances at night. Moreover, this solution should not be overly complex and should be cost-effective to manufacture. [Overview of the project]

[Modes for carrying out the invention]

[0034] Figure 1 shows an exploded view of the sleep training device 100. The sleep training device 100 may have functions that combine a sunrise alarm, a night light, a wind-down clock, an alarm clock, and an audio playback device. For example, the sleep training device 100 can generate light and sound in a way that helps the user fall asleep as part of a wind-down routine and / or help the user wake up gently as part of a wake-up routine. The device 100 can generate sounds at varying volumes and emit lights of varying colors and brightnesses before, during, and after the wake-up and wind-down routines.

[0035] The device 100 may comprise an outer housing 102, a front panel 108 connected to the front 200 of the outer housing 102, and a rear cover 112 connected to the rear 210 of the outer housing 102. The device 100 may further comprise a front textile 106 that partially covers or is connected to the front panel 108, and a rear textile 110 that partially covers or is connected to the rear cover 112.

[0036] The outer housing 102 may be formed in a substantially partial spherical, truncated bowl shape, or partial frustoconical shape. The device 100 may include a substantially flat housing bottom 144 connected to the base of the outer housing 102. The outer housing 102 may be formed substantially as a partial cone, a partial cylinder, a partial dome, or a combination thereof.

[0037] The flat housing bottom 144 allows the device 100 to be placed on substantially flat surfaces such as tables, countertops, shelves, and nightstand tops. The housing bottom 144 may constitute or be covered by one or more legs 146 having friction pads, friction-inducing surfaces, or surface structures to prevent the device 100 from sliding off the mounting surface or being accidentally moved by the user. The legs 146 may be made of or contain rubber, synthetic rubber, a polymer with a high coefficient of friction, or a combination thereof. The legs 146 are substantially flat and may be formed as elongated ovals (e.g., peanut-shaped), circles, rectangles, rhombuses, or a combination thereof. As shown in Figure 2B, the legs 146 may slightly elevate the outer housing 102 from the platform.

[0038] The outer housing 102 may have a curved upper portion 104, along which a number of openings 166 or apertures are provided. The openings 166 or apertures allow a user of device 100 to access activatable physical buttons (e.g., to apply user input) to control the functions of device 100.

[0039] The device 100 may include a rest button 148 and a rise button 150. The rest button 148 and the rise button 150 may be housed in or protrude through an opening 166 or aperture provided along the curved upper part 104 of the outer housing 102.

[0040] The rest button 148 may be concave relative to the external surface of the outer housing 102 surrounding the rest button 148. The rest button 148 can be physically pressed when the user is ready to start a sleep-related program (e.g., a wind-down program). The rise button 150 may be convex relative to the external surface of the outer housing 102 surrounding the rise button 150. The rise button 150 can be physically pressed when the user is ready to start another sleep-related program (e.g., a wake-up program). As described later, the user can set sleep-related programs and control the light and sound emitted from the device 100.

[0041] Alternatively, the rest button 148 may be convex and the rise button 150 may be concave.

[0042] Furthermore, users can control sleep-related programs from client devices 502 (see Figure 5), such as smartphones, tablets, laptops, smartwatches, personal entertainment devices, or combinations thereof.

[0043] In some variations, the rest button 148 and / or the rise button 150 (or any additional buttons on device 100) may comprise one or more capacitive touch components or sensors.

[0044] The device 100 may include a toggle switch 152. The outer housing 102 may have a toggle opening 154 or aperture along the side of the outer housing 102 to allow a user of the device 100 to access the toggle switch 152.

[0045] The toggle switch 152 can be used to disable and enable alarm programs stored in the memory unit of device 100. The toggle switch 152 may have a circular button that can move back and forth within the toggle opening 154. Part of the toggle switch 152 may be colored to indicate to the user whether the alarm is enabled or disabled.

[0046] Any one of the outer housing 102, rear cover 112, and housing bottom 144 may be made in part from a polymer material or may contain a polymer material. For example, any one of the outer housing 102, rear cover 112, and housing bottom 144 may be made in part from or contain acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polypropylene (PP), one or more acrylic resins, a combination or composite thereof, or any combination with a polymer material.

[0047] Any one of the outer housing 102, rear cover 112, and housing bottom 144 may be made in part from a metal material, thermoplastic resin, ceramic, or a combination thereof. For example, any one of the outer housing 102, rear cover 112, and housing bottom 144 can be manufactured as a single molded part of ABS resin. In some modifications, part of the outer housing 102 may be made from an organic material such as wood or bamboo.

[0048] Device 100 may include a battery 164. The battery 164 may be connected to the bottom of the housing 144. The battery 164 can be powered via a power supply port 214 on the battery, which is accessible through the outer housing 102, as shown in Figure 2C.

[0049] The outer housing 102 is also used to house, hold, or store one or more portable power sources, such as portable batteries. The batteries may include rechargeable batteries, disposable batteries, or a combination thereof. For example, the batteries may include multiple C-size batteries or multiple AA-size batteries. The batteries may be alkaline batteries, lithium-ion batteries, nickel-cadmium batteries, or nickel-metal hydride batteries. The batteries may be placed within the space inside the main speaker housing 140.

[0050] The front panel 108 may be fixed, glued, or otherwise connected to the front surface 200 of the outer housing 102. The rear cover 112 may be fixed, glued, or otherwise connected to the rear surface 210 of the outer housing 102.

[0051] As will be described later, at least a portion of the rear cover 112 may be provided with holes or openings arranged in a densely packed circular pattern, in which portion the rear cover 112 can function as a rear speaker grille 158.

[0052] The front panel 108 may be made of a polymer material in part, or may contain a polymer material. For example, the front panel 108 may be made of polymethyl methacrylate (PMMA), acrylonitrile butadiene styrene (ABS), or polycarbonate (PC).

[0053] As described later, at least a portion of the front panel 108 may be provided with holes or openings arranged in a densely packed circular pattern, in which portion the front panel 108 can function as a front speaker grille 300.

[0054] Furthermore, as shown in Figure 3A, at least a portion of the front panel 108 may be provided with holes or openings 302 arranged in a dense rectangular pattern, in which portion the front panel 108 can function as a clock display unit 204.

[0055] Returning to the front textile 106 and rear textile 110, the front textile 106 may be partially wrapped around the front panel 108, and the rear textile 110 may be partially wrapped around the rear cover 112. For example, the front textile 106 may be wrapped around the outer edge of the front panel 108. Also, for example, the rear textile 110 may be wrapped around the outer edge of the rear cover 112.

[0056] The front textile 106 and rear textile 110 may be fabric pieces containing warp threads running longitudinally and weft threads running transversely, as viewed with respect to the x and y axes in Figure 2B. The warp threads are undyed, and the weft threads may be dyed.

[0057] For example, the front textile 106 and the rear textile 110 are each pieces of natural linen, with the linen warp threads being undyed and the linen weft threads being dyed.

[0058] Alternatively, the front textile 106 and rear textile 110 may be made from other materials, such as synthetic fibers, cotton, other fabrics, combinations thereof, or combinations of these materials with natural linen derived from flax.

[0059] The warp threads are a collection of threads that run vertically and form the basis of the fabric. The weft threads are a collection of threads that run horizontally. The weft threads are woven substantially perpendicular to the warp threads, which can form a grid pattern in the fabric. The warp threads are undyed, and the weft threads may be dyed. This pattern allows the fabric (e.g., front textile 106) to produce a light-reducing effect or to reduce the amount of light emitted through the fabric.

[0060] In some variations, the warp threads may be dyed while the weft threads remain undyed.

[0061] Each of the front textile 106 and the rear textile 110 may be covered with a polymer coating. For example, each of the front textile 106 and the rear textile 110 may be covered with a dynamic silicone coating.

[0062] One of the technical challenges faced by the applicant was how to design a sleep training device 100 (e.g., a combination of a sunrise alarm, night light, wind-down clock, alarm clock, and audio playback device) that is aesthetically pleasing in a bedroom environment and does not resemble an unsightly high-tech device. One technical solution discovered and developed by the applicant is to cover the front and back of the sleep training device 100 with a specially designed textile disclosed herein. This textile adds visual appeal to the sleep training device 100, giving it an almost unassuming appearance and allowing it to blend into the bedroom environment. Furthermore, the specially designed textile disclosed herein also has the function of reducing and softening the light emitted from inside the device 100.

[0063] In other variations, instead of the front textile 106 and / or rear textile 110, the front and back of the device 100 may be covered with a light-transmitting polymer component.

[0064] The front panel 108 may have a screen-printed layer 118 that coats or covers the front surface and edges of the front panel 108. The screen-printed layer 118 may form a feather-like or blurred gradient to diffuse the light passing through the front panel 108. The screen-printed layer 118 can soften or dim the light generated by a light source (e.g., an LED) inside the device 100.

[0065] The screen-printed layer 118 may be printed or bonded to the front and edges of the front panel 108. The screen-printed layer 118 can also provide the additional function of preventing the edges of the front panel 108 from accidentally damaging the front textile 106. The screen-printed layer 118 can first be applied to the front and edges of the front panel 108 and then cured by ultraviolet light.

[0066] Device 100 may include a capacitive touch component 120. The capacitive touch component 120 may be located on the front 200 of the outer housing 102 behind the front panel 108. The capacitive touch component 120 may be conformed to the shape or design of the lower part of the front panel 108. The capacitive touch component 120 may be electrically connected to the processor of device 100.

[0067] In other modifications, the capacitive touch component 120 may be bonded to at least a portion of the front panel 108. In other modifications, the capacitive touch component 120 may constitute at least a portion of the front panel 108.

[0068] The capacitive touch component 120 may be positioned beneath the outer housing 102 on the curved upper part 104 of the device 100 for the purpose of displaying the time when the user taps the curved upper part 104 of the device 100.

[0069] The capacitive touch component 120 can be activated by the user touching a portion of the front textile 106. When the capacitive touch component 120 is activated, the user can control the brightness and volume of the device 100, as will be described later with respect to Figure 2B.

[0070] The user can also power on the device 100 or display the clock display 204 by physically touching or making contact with the capacitive touch component 120 via the front textile 106 and front panel 108 (see Figure 2B). Furthermore, the user can switch between one or more preset settings for light and / or sound by continuously touching or making physical contact with the capacitive touch component 120 via the front textile 106 and front panel 108.

[0071] The capacitive touch component 120 may be made of or contain a metallic material, a semiconductor material, or a combination thereof. For example, the capacitive touch component 120 may be made of or contain stainless steel.

[0072] Device 100 may include a plurality of clock light-emitting diodes (LEDs) 122. The clock LEDs 122 face the front of device 100 and are located behind the front panel 108. The clock LEDs 122 may have a grid consisting of 21 × 7 individual LEDs in a rectangular pattern. Alternatively, the clock LEDs 122 may have a grid with approximately 5 to 50 LEDs arranged vertically and approximately 10 to 100 LEDs arranged horizontally.

[0073] The clock LED 122 may be configured to emit light through the front textile 106 and front panel 108, as shown in Figure 2B, and to display the time to the user via the clock display unit 204. The clock LED 122 may also display patterns such as the moon and stars or the sun to indicate to the user that a wind-down routine or wake-up routine is in progress.

[0074] The device may include an internal front lower region 126. The internal front lower region 126 may include speaker receiving portions 306 for inserting one or more front speakers 128 (see Figure 3A). The internal front lower region 126 may include an LED opening 302 for a clock between the speaker receiving portions 306, allowing the user to see the LED 122 for the clock.

[0075] The internal front lower region 126 may be located in front of the clock LED 122. The internal front lower region 126 may be located behind the capacitive touch component 120 and the front panel 108.

[0076] The internal front lower region 126 may be made of, or contain, a polymer material, a metallic material, or a combination thereof, in part or in whole. For example, the internal front lower region 126 may be made of, or contain, a combination of, acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polypropylene (PP), one or more acrylics including opal acrylic, or metallic materials.

[0077] The device may include a clock LED board 124. The clock LED 122 may be placed on the clock LED board 124, fixed, or otherwise connected. The clock LED board 124 is shaped and sized to accommodate the clock LED 122. The clock LED board 124 may be connected to an internal front lower region 126.

[0078] Device 100 may include a dimming film 130. The dimming film 130 may be placed on the LED opening 302 for the clock in the internal front lower region 126. The dimming film 130 can soften the light emitted from the LED 122 for the clock. For example, the dimming film 130 can be colored substantially yellow. The dimming film 130 may be made of a translucent plastic such as acrylic (e.g., opal acrylic).

[0079] Alternatively, the light-adjusting film 130 may be made of or comprise a portion of another type of polymer material. For example, the light-adjusting film 130 may be made of or comprise a portion of polypropylene (PP), acrylonitrile butadiene styrene (ABS), polycarbonate (PC), a combination thereof, or any combination with acrylic.

[0080] The device 100 may have one or more main LEDs 132. The main LEDs 132 may be arranged on a main LED substrate 134 located behind the internal front lower region 126. The main LEDs 132 as a whole may be arranged on the main LED substrate 134 in a trapezoidal pattern, rectangular pattern, diamond pattern, triangular pattern, ring pattern, or elliptical pattern.

[0081] Although Figure 1 shows only a single-stage or single-layer arrangement of the main LED 132, this disclosure also envisions stacking the main LED 132 in multiple stages or layers. The main LED 132 may be arranged such that each LED 132 is separated from adjacent LEDs 132 by space or gaps. The main LED 132 may be arranged facing upward in the vertical direction.

[0082] Both the main LED 132 and the clock LED 122 may contain one or more red, green, blue, and white (RGBW) LEDs. The main LED 132 and the clock LED 122 may also contain one or more active-matrix organic light-emitting diodes (AMOLEDs), super AMOLEDs, or a combination thereof.

[0083] Device 100 may include a main LED dimmer 136. The main LED dimmer 136 may be positioned directly above the main LED substrate 134. The main LED 132 may emit light that passes through the main LED dimmer 136. The main LED dimmer 136 may be configured to diffuse or soften the light generated by the main LED 132 before the light reaches the front surface 200 of device 100. Thus, the main LED dimmer 136 can be formed to cover the entire main LED substrate 134.

[0084] The main LED dimmer 136 may be made of transparent plastic. Alternatively, the main LED dimmer 136 may be made of a polymer material configured to dissipate the heat generated by the main LED 132. For example, the main LED dimmer 136 may be made of or contain ABS, polycarbonate, a combination thereof, or any combination with a polymer material.

[0085] The main LED dimmer 136 includes, or may have, one or more surface features or textures configured to diffuse the light produced by the main LED 132. The main LED dimmer 136 may be covered with one or more coatings configured to diffuse the light produced by the main LED 132 or to dissipate heat.

[0086] Device 100 may include an internal reflector 138. The internal reflector 138 may be located behind or behind the front panel 108. The internal reflector 138 may have a concave composite curved shape toward the front side of device 100. The composite curved shape of the internal reflector 138 can guide the light generated by the main LED 132 toward the front side of device 100. Therefore, when a sleep-related program is started, the light generated by the main LED 132 can be shone through the front panel 108 and the front textile 106.

[0087] The front panel 108 is connected to the edge of the internal reflector 138, and the front panel 108 may be partially housed within the internal reflector 138. As will be described later in Figures 4A and 4B, the internal reflector may include components such as shelves for housing the main LED dimmer 136 and the main LED board 134.

[0088] One of the technical challenges faced by the applicant was how to design a device 100 that dims the light emitted from the main LED 132 so as not to disturb the user's sleep. One of the technical solutions discovered and developed by the applicant is the configuration disclosed herein, namely, a main LED dimmer 136 diffuses the light before an internal reflector 138 directs the light generated by the main LED 132 toward the front textile 106. To attenuate or control the amount of light experienced by the user, the front textile 106 may be manufactured to diffuse or attenuate light.

[0089] Device 100 may include a main speaker housing 140 and a main speaker 142. The main speaker housing 140 may be configured to connect to a portion of the main speaker 142. The main speaker housing 140 may be sized to fit within the outer housing 102. The main speaker housing 140, together with the internal reflector 138 and the main speaker 142, can form a sealed acoustic environment to control the sound produced by the main speaker 142.

[0090] The main speaker housing 140 may be formed substantially as a partial sphere, a cut-off bowl shape, or a partial frustoconical shape.

[0091] In one modified example, the main speaker housing 140 may be detachable or separable from the outer housing 102. In another modified example, the main speaker housing 140 may be fixed to the outer housing 102 by adhesive, fasteners, screw connections, or a combination thereof.

[0092] The main speaker housing 140 may be made of or contain polymer materials, metal materials, or a combination thereof. For example, the main speaker housing 140 may be made of or contain acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polypropylene (PP), one or more acrylic resins, a combination or composite thereof, or any combination with metal materials.

[0093] The main speaker 142 may be controlled by one or more electronic components of device 100. In addition to supporting the main speaker 142, the main speaker housing 140 and / or outer housing 102 may also house or serve as containers for one or more electrical components, such as wires, circuits, conductors, interfaces, circuit boards, power supply components, or combinations thereof. The electrical components may connect a processor or another circuit or chip on PCB 156A to the main speaker 142, the capacitive touch component 120, or a combination thereof.

[0094] The main speaker 142 may have a rearward-facing cone 160 and a forward-facing pole piece 162. The main speaker 142 may be positioned behind the internal reflector 138 and facing the rear surface 210 of the outer housing 102. The main speaker 142 may radiate sound toward the rear surface 210 of the outer housing and through the rear speaker grille 158 and rear textile 110 of the rear cover 112. The rear cover 112 (including the rear speaker grille 158) and rear textile 110 can attenuate or soften the sound radiated from the main speaker 142.

[0095] One of the technical challenges faced by the applicant was how to design a configuration that controls the sound emitted by device 100 so as not to disturb a sleeping user. One of the technical solutions discovered and developed by the applicant is the configuration disclosed herein, namely, the main speaker 142 facing the rear of device 100, and the main speaker housing 140, the main speaker 142, and the internal reflector 138 forming a sealed acoustic environment that controls and enhances the sound produced by the main speaker 142. Furthermore, because the main speaker 142 faces the rear of device 100, the sound is partially absorbed or mitigated by the rear cover 112 and rear textile 110, so that it does not become an unpleasant sound when heard by a sleeping or dozing user.

[0096] The device may comprise one or more printed circuit boards (PCBs) 156A and 156B. Each of the one or more PCBs 156A or PCB 156B may comprise one or more chips, modules, integrated circuits (ICs), sensors, interfaces, high-speed buses, or combinations thereof. The one or more PCBs 156A or PCB 156B may be housed within the outer housing 102.

[0097] PCB156A may have a function to control the main speaker 142. PCB156A may be positioned between the main speaker housing 140 and the internal reflector 138. PCB156A may be semi-circular in shape so as to fit within the main speaker housing 140. PCB156A may be bonded or connected to the main speaker housing 140. Alternatively, PCB156A may be bonded or connected to the main speaker 142.

[0098] The PCB 156A and the main speaker 142 may be connected to each other or to the interior of the outer housing 102 by fasteners, screws, threaded connections, press-fits, clips, clasps, adhesives, heat staking, thermoplastic staking by laser welding or ultrasonic welding, or a combination thereof. For example, the PCB 156A, main speaker 142, main speaker housing 140, internal reflector 138, or a combination thereof may be connected by staking or press-fitting through holes or slots on each substrate to polymer studs, posts, ribs, bosses, or any combination thereof that protrude from a portion of the inner surface of the outer housing 102.

[0099] PCB156B may have the function of controlling the main LED132 and the clock LED122. PCB156B may be positioned between the internal reflector138 and the housing bottom144 and below the main LED board134. The main LED board134 may be positioned elevated from PCB156B, thereby separating the LED board134 and the main LED132 from the electrical components on PCB156B by a gap or distance. PCB156B may be formed to rest on the housing bottom144.

[0100] The PCB 156B and the housing bottom 144 may be connected to each other or to the interior of the outer housing 102 by fasteners, screws, threaded connections, press-fits, clips, clasps, adhesives, heat staking, thermoplastic staking by laser welding or ultrasonic welding, or a combination thereof. For example, the PCB 156B, the main LED board 134, the housing bottom 144, the internal reflector 138, or a combination thereof may be connected by staking or press-fitting through holes or slots on each board to polymer studs, posts, ribs, bosses, or any combination thereof that protrude from a portion of the inner surface of the outer housing 102.

[0101] Figure 2A shows a perspective view of an example of a sleep training device 100. The outer housing 102 may have a front surface 200 including a leading edge 202 as shown in Figure 2A, and a back surface 210 as shown in Figure 2C. The front surface 200 of the outer housing 102 may be at least partially covered by a front textile 106. The front textile 106 can function as the front surface of the sleep training device 100.

[0102] The front textile 106 may be formed concavely from the leading edge 202, or it may be positioned slightly rearward (or inward) relative to the leading edge 202 of the outer housing 102. The leading edge 202 of the outer housing 102 may also partially protect the front textile 106 from damage during transport or normal use.

[0103] The rest button 148 may be concave relative to the outer surface of the curved upper part 104 of the outer housing 102 surrounding the rest button 148. The rest button 148 can be physically pressed when the user is ready to start a sleep-related program (e.g., a wind-down program).

[0104] The rise button 150 may be convex relative to the outer surface of the curved upper part 104 of the outer housing 102 surrounding the rise button 150. The rise button 150 can be physically pressed when the user is ready to start another sleep-related program (e.g., a wake-up program).

[0105] Figure 2B shows a front view of the sleep training device 100. The device 100 may have a clock display unit 204 composed of multiple clock LEDs 122. The clock LEDs 122 can emit or project light through the front textile 106, making the clock display unit 204 visible to the user through the front textile 106.

[0106] The clock display unit 204 may be positioned toward the lower part of the front surface 200 of the outer housing 102. The clock display unit 204 may be connected to the real-time clock integrated circuit (IC) of the device 100.

[0107] Alternatively, the clock display unit 204 may display symbols such as the moon, stars, or sun to indicate to the user whether a wind-down routine or a wake-up routine is in progress.

[0108] The device 100 may include a touch-sensitive brightness adjustment switch 206 and a touch-sensitive volume adjustment switch 208. The brightness adjustment switch 206 and the volume adjustment switch 208 can be operated via a capacitive touch component 120 located on the back of the front textile 106 and the front panel 108.

[0109] The brightness adjustment switch 206 may be located above or below the clock display 204 on the front surface 200 of the device 100. To increase the brightness of the device 100 while in use, the user can physically touch or contact the top of the clock display 204. To decrease the brightness of the device 100 while in use, the user can physically touch or contact the bottom of the clock display 204.

[0110] The volume control switch 208 may be located on the front 200 of the device 100, on the side of the clock display unit 204. To increase the volume of the device 100 while in use, the user can physically touch or contact one side of the clock display unit 204 (the right side of the clock display unit 204 in Figure 2B). To decrease the volume of the device 100 while in use, the user can physically touch or contact the opposite side of the clock display unit 204 (the left side of the clock display unit 204 in Figure 2B).

[0111] Figure 2C shows a rear view of the sleep training device 100. The rear surface 210 of the outer housing 102 may be at least partially covered by the rear textile 110. The rear surface 210 of the outer housing 102 may include a rear edge 212.

[0112] The rear textile 110 may be formed concavely from the trailing edge 212 of the outer housing 102, or positioned slightly behind (or in front of) the trailing edge 212. The trailing edge 212 of the outer housing 102 may also partially protect the rear textile 110 from damage during transport or normal use.

[0113] Device 100 may have a power supply port 214 for receiving a charging cable. The charging cable can be plugged into the power supply port 214 to charge the battery 164. The power supply port 214 is accessible through an opening or notch provided along the outer housing 102, rear textile 110, and rear cover 112. The power supply port 214 may include a Universal Serial Bus (USB) port such as a micro USB, mini USB port, or USB-C port. The power supply port 214 may also have a coaxial barrel receptacle for receiving a coaxial barrel connector. For example, the power supply port 214 may receive a connector for a Universal AC adapter.

[0114] Alternatively, in addition to the battery 164, the device 100 may have an inductive charge receiver housed in the outer housing 102 for receiving wireless power.

[0115] Figure 2D shows another front view of the sleep training device 100. This figure further shows the yarn of the front textile 106, which has warp threads running longitudinally and weft threads running transversely. As shown in Figure 2D, the warp threads are undyed, and the weft threads may be dyed. The yarns may run horizontally and vertically with respect to the x and y axes. The front textile 106 (together with the rear textile 110) adds visual appeal to the sleep training device 100. The front textile 106 (together with the rear textile 110) gives the device 100 a nearly rustic appearance, allowing the device 100 to blend into the bedroom environment. Furthermore, the specially designed front textile 106 can function to dim and soften the light emitted by the main LED 132 from inside the device 100.

[0116] Figure 2E is a black and white image showing a front view of an example of a sleep training device 100 in the illuminated state. When the device 100 is illuminated by the main LED 132, the front textile 106, together with the front panel 108 and the screen-printed layer 118, may display a "sunrise" or "sunset" gradient along the front surface 200 of the device 100. The screen-printed layer 118 can give the device 100 a feathering effect when the device 100 is illuminated from the inside. This softens the sharpness of the light, giving the light emitted from the device 100 a warmer impression. The screen-printed layer 118 may also form a transition region 207 along the front surface 200 of the device 100 when the device 100 is illuminated from the inside. As shown in Figure 2E, the transition region 207 is a substantially horizontal region or horizontal band along the front surface 200 of the device 100, and can make the light appear to melt or blur. In this way, when illuminated from within, device 100 appears to mimic the sun at sunset or sunrise.

[0117] One of the technical challenges faced by the applicant was how to design the sleep training device 100 so that it displays a gentle light that mimics sunrise or sunset. One technical solution discovered and developed by the applicant is to provide a blur effect that represents sunrise or sunset using a screen-printed layer 118 placed on the front panel 108. This blur effect is a gradual transition, which can give the front 200 of the device 100 a gentle appearance. The blur and feather effects can be observed in all colors emitted by the main LED 132.

[0118] Figure 3A shows a front view of the front panel 108 of the sleep training device 100. The front panel 108 may include one or more front speaker grilles 300 and one or more LED openings 302. The front speaker grilles 300 may be located on both sides of the LED openings 302. Each front speaker grille 300 may have multiple individual openings.

[0119] The front panel 108 may have a front panel edge 304 that can be configured to connect to the outer housing 102. The front textile 106 may be wrapped around the front panel 108 so that at least a portion of it fits between the front panel 108 and the outer housing 102.

[0120] The front panel 108 may have multiple LED openings 302 toward the bottom of the front panel 108. The multiple LED openings 302 may be collectively arranged in a rectangular pattern.

[0121] Multiple LED apertures 302 may be collectively arranged in a circular pattern, an elliptical pattern, a triangular pattern, a diamond pattern, or a combination thereof.

[0122] Figure 3B shows a front view of the internal front lower region 126 of the sleep training device. The internal front lower region 126 may have one or more speaker receiving portions 306. One or more speaker receiving portions 306 can function as housings for front speakers 128.

[0123] One or more speaker receiving sections 306 may be located on either the left or right side of the internal front lower region 126.

[0124] Figure 3C shows a front view of the rear cover 112 of the sleep training device 100. The rear cover 112 may include a rear speaker grille 158. The rear speaker grille 158 may be located near the center of the rear cover 112. The rear speaker grille 158 can function as a screen or cover for the main speaker 142. The rear speaker grille 158 may have multiple holes or openings arranged in a densely packed circular pattern.

[0125] Alternatively, the rear speaker grille 158 may have multiple holes or openings arranged substantially in a rectangular, triangular, or elliptical pattern.

[0126] The rear cover 112 may be made of or comprise a portion of polymer materials. For example, the rear cover 112 may be made of polymethyl methacrylate (PMMA), acrylonitrile butadiene styrene (ABS), or polycarbonate (PC).

[0127] The rear cover 112 may be provided with a snap-fit ​​308. The snap-fit ​​308 can be used to secure the rear cover 112 to the outer housing 102. The snap-fit ​​308 may have a projection for locking onto the rear surface 210 of the outer housing 102.

[0128] The rear textile 110 may be wrapped at least partially around the rear cover 112. The rear textile 110 may be wrapped around the rear cover 112 such that at least a portion of the rear textile 110 is positioned between the rear cover 112 and the outer housing 102.

[0129] The rear cover 112 may include a rear cover edge 310. The rear cover edge 310 may be positioned toward the bottom of the rear cover 112. The rear cover edge 310 may be positioned slightly below and in contact with the outer housing 102 so that the rear cover 112 connects with the outer housing 102. The outer housing 102 may rest on the rear cover edge 310.

[0130] Figure 4A shows a front view of the internal reflector 138 of the sleep training device 100. The internal reflector 138 may include a raised portion 400. The raised portion 400 may extend at least partially along the front surface of the internal reflector 138. The front panel 108 of the device 100 (not shown in Figure 4A) can be fitted onto the raised portion 400 so that it fits inside the internal reflector 138 when assembled.

[0131] The internal reflector 138 may have shelf sections 402 on both sides of the internal reflector 138. The shelf sections 402 may hold the main LED board 134 that holds the main LED 132, and the main LED 132 may be oriented vertically upward. The main LED dimmer 136 may be placed on the main LED board 134 and molded to fit within the internal reflector 138 above the shelf sections 402.

[0132] The main LED dimmer 136 and the main LED board 134 may be connected to the internal reflector 138 via fasteners, screws, threaded connections, or a combination thereof.

[0133] Figure 4B shows a front perspective view of the internal reflector 138 of the sleep training device 100. The internal reflector 138 may include a curved back surface 139. The curved back surface 139 of the internal reflector 138 may be formed as a substantially composite curved surface shape. The curved back surface 139 of the internal reflector 138 may be configured to reflect and guide the light generated by the multiple main LEDs 132 toward the front panel 108 so that when a sleep-related program is started, the light generated by the main LEDs 132 passes through the front panel 108 and the front textile 106 and illuminates them.

[0134] One of the technical challenges faced by the applicant was how to design the sleep training device 100 so that the light generated by the main LED 132 would be softened and dimmed, yet still provide enough light to wake the user when the wake-up program was initiated. One technical solution discovered and developed by the applicant is to design the device 100 having a curved back surface 139 having a substantially composite curved shape for the internal reflector 138 disclosed herein. This curved back surface 139 reflects the light generated or emitted by the main LED 132 (positioned facing vertically upward) and directs it toward the front panel 108 and front textile 110. This gives the light emitted from the device 100 and reaching the user a warm impression, mimicking sunlight coming through a window curtain.

[0135] Returning to Figure 1, device 100 may include one or more processors connected to PCB 156A and / or PCB 156B. The one or more processors may include a communication unit processor, a system processor, or a combination thereof. The communication unit processor may be part of a communication chip along with a communication unit memory and a real-time clock IC. The real-time clock IC can be used by the processor to track time when a user activates a timer function through an application on client device 502 (see Figure 5) or when setting up a time-based sleep-related program.

[0136] The communication chip may be part of a communication module connected to PCB156A and / or 156B. The communication unit processor may be connected to the antenna.

[0159] The voice-enabled assistant device can communicate with a voice-enabled assistant server over a network. The voice-enabled assistant device can detect voice commands from the user and cause the sleep training device to perform actions. For example, such actions may include starting or stopping the sleep training device, adjusting the volume of sounds produced by the main speaker 142 and / or front speaker 128 of the sleep training device 100, playing, pausing, or resuming tracks or sounds stored in the memory of the sleep training device 100 or streamed by the sleep training device 100, starting or stopping the timer function of the sleep training device 100, adjusting the brightness or luminosity of the light produced by the main LED 132, adjusting the color of the light produced by the main LED 132, enabling or starting the lock function, downloading multimedia content from a server or other device, downloading software updates from a server or other device, or a combination thereof.
