[0005] overview This specification describes a system of range extenders and associated methods. The range extenders described herein have improved robustness, simplicity, and compactness compared to conventional range extenders.

[0006] In one aspect, a range extender is disclosed. The range extender includes a housing having an upper housing member and a lower housing member, an audio sensor, a heat sink assembly, a circuit board assembly, a speaker, and a light ring assembly. The housing includes an upper housing member having a generally cylindrical vertical wall and a top end connected to a first end of the vertical wall via a rounded corner, the vertical wall being generally cylindrical about a central axis and having an inner surface and an opposing outer surface, at least a portion of the vertical wall having a non-uniform thickness in the direction of the longitudinal axis based on the outer surface of the vertical wall being curved in the direction of the longitudinal axis, the inner surface of the vertical wall being substantially parallel to the longitudinal axis, and the top end being concave in a side view of the top end. The bottom housing member is connected to the top housing member at a second end of the vertical wall, the bottom housing member having a bottom outer surface and an opposing inner surface, the bottom outer surface defining a plane substantially perpendicular to the central axis, the bottom housing member including a curved edge between the bottom outer surface of the top housing member and the vertical wall. The sound sensor is disposed within the housing and proximate to a top end of the top housing member. The heat sink assembly includes a heat sink and one or more antennas, the heat sink having a cylindrical shape with a radius within a tolerance threshold distance less than a radius of the inner surface of the vertical wall of the top housing member. The circuit board assembly is disposed within the housing proximate to the heat sink assembly, the circuit board assembly communicatively coupled to the one or more antennas, causing the one or more antennas to provide wireless nodes for a wireless mesh network. The speaker assembly is disposed within the housing and connected to the circuit board assembly, the speaker assembly aligned with a plurality of holes in the bottom housing member. A light ring assembly is connected to a bottom exterior surface of the bottom housing member, the light ring assembly being configured to reflect light radially away from the central axis and to diffuse the light to provide a soft glow beneath the bottom housing member.

[0007] In one aspect, a system is disclosed. The system includes a plurality of antennas, a circuit board assembly, a heat sink, a microphone, a speaker assembly, and a housing. The plurality of antennas are configured to transmit and receive communication signals. The circuit board assembly is communicatively connected to the plurality of antennas to provide a wireless node in a wireless mesh network. The heat sink is disposed proximate to the circuit board. The microphone is connected to the circuit board. The speaker assembly is connected to the circuit board such that the circuit board is located between the speaker assembly and the heat sink. The housing has a generally cylindrical shape about a central axis and includes first and second housing members. The first and second housing members form an enclosure around the plurality of antennas, the circuit board assembly, the heat sink, the microphone, and the speaker assembly. The first housing member includes a vertical wall of a cylindrical shape having an inner surface substantially parallel to a central axis. The second housing member includes a plurality of holes aligned with the audio output devices. The light ring assembly is configured to provide a soft glow beneath the second housing member.

[0008] These are just a few examples of how the described techniques and devices can be used to enable range extender devices. Other examples and embodiments are described throughout this specification. Now this specification turns to an example device, and then an example system is described.

[0009] Exemplary Apparatus 1 illustrates a top rear perspective view 100 of an exemplary embodiment of a range extender 102. The range extender 102 includes a housing 104 having a substantially cylindrical shape with rounded edges. The housing 104 has a central axis 106 (e.g., a longitudinal axis). The housing 104 has a smooth exterior surface with nearly invisible features. In one aspect, the housing 104 includes a top housing member 108 and a bottom housing member 110.

[0010] As described further below, the housing includes a seam 112 on an exterior surface of the housing 104. The seam 112 is aligned where the top housing member 108 is attached to the bottom housing member 110. The top housing member 108 may be coupled (e.g., threaded, fastened, clamped, pressed, glued, ultrasonically welded, etc.) to the bottom housing member 110. The range extender 102 also includes a number of holes 114 in the top housing member 108 that are aligned with an audio sensor (not shown in FIG. 1 ) located in the housing 104 for receiving audio input (e.g., voice commands) from a user. The bottom housing member 110 includes a privacy switch 116 for disabling or turning off the audio sensor.

[0011] The range extender device 102 extends the range of an existing Wi-Fi network. In some aspects, the range extender device may function as a node in a wireless mesh network. For example, the range extender device may wirelessly communicate with an access point in a user's home to extend the range of the local wireless network.

[0012] FIG. 2 illustrates a bottom rear perspective view 200 of the exemplary embodiment of the range extender of FIG. 1, where the bottom housing member 110 includes a number of holes 202. The holes 202 are perpendicular to the exterior surface of the bottom housing member 110. The holes 202 align with an audio output device (e.g., a speaker) in the housing 104 to provide a path for audio output from the audio output device. Additionally, the bottom housing member 110 includes an opening 204 that aligns with a power connector through the housing 104, such as a barrel jack of the range extender 102. As will be described further below, a light ring assembly 206 is attached to the bottom housing member 110. The light ring assembly 206 provides a soft glow of light beneath the range extender 102 that indicates different operating states of the device. A soft glow (also referred to as "underglow") is a light that is illuminated by a light source 206 that illuminates the range extender 102 from above. The light ring assembly 206 is preferably a light source that illuminates the range extender 102 from below. The light ring assembly 206 may be ... The glow is a diffuse light that radiates below the range extender 102 and reflects off the surface on which the range extender 102 is placed. In one example, if the microphone is muted, the light glow may be red or amber. If the range extender 102 is active in a call (e.g., a Wi-Fi call, a Voice-over-Internet Protocol (VoIP) call, etc.), the light glow may be red or amber. The glow may be a flashing blue light. Alternatively, the glow may be white when the user is interacting with a virtual assistant running on the range extender. Thus, the light ring assembly 206 may be configured to illuminate the bottom light with any suitable color and brightness to indicate the operational state of the range extender 102. and / or blinking patterns.

[0013] 3A-3D show various elevation views of the range extender 102. FIG. 3A is a front view of the range extender 102 with the central axis 106 displayed vertically. The upper housing member 108 includes a vertical wall 302 that is generally cylindrical (e.g., has an x-axis radius substantially equal to the y-axis radius such that the x-axis radius is within a tolerance of about 10 millimeters of the y-axis radius) about the central axis 106. The upper housing member 108 also includes an upper end 304 that is recessed downward in the front view 300, such that the upper end 304 curves toward the vertical wall 302. The upper end 304 is connected to a first end (e.g., top end) of the vertical wall 302 via a rounded edge 306.

[0014] The bottom housing member 110 shares the central axis 106 with the top housing member 108 and is coupled to the top housing member 108 at a second end (e.g., a lower end) opposite the first end of the vertical wall 302. The bottom housing member 110 includes a rounded edge 308 that may have a similar radius as the rounded edge 306 of the top housing member 108. In the illustrated example, the bottom housing member 110 is substantially shorter in the direction of the central axis 106 than the top housing member 108 such that the seam 112 is located in the lower half of the housing 104. However, the bottom housing member 110 and the top housing member 108 may be of any suitable height such that the seam 112 is located anywhere on the housing where the top housing member 108 is connected to the bottom housing member 110. The radius of the vertical wall 302 about the central axis 106 may be any suitable radius, such as a radius within a range of about 38 millimeters (mm) to about 65 mm.

[0015] The bottom housing member 110 includes a bottom exterior surface (not shown) that defines a planar surface 310. Connected to the bottom exterior surface of the bottom housing member 110 is the light ring assembly 206. Thus, the bottom housing member 110 is disposed between the top housing member 108 and the light ring assembly 206. The legs 312 are connected to the light ring assembly 206. The legs 312 may be formed of any suitable material (e.g., an elastomer) having a sufficiently high coefficient of friction to reduce sliding between the housing 104 and the surface on which the housing 104 rests. In some aspects, the legs 312 may be glued to the light ring assembly 206.

[0016] 3B illustrates a rear view 320 of the range extender 102. As shown in the rear view 320, the bottom housing member 110 includes an opening 204 that provides accessibility to connect a cable (e.g., a power cable) to a power connector 322 within the housing to transfer power to the range extender 102. In one aspect, the privacy switch 116 may be vertically aligned with the opening 204. However, the privacy switch 116 may be located in any suitable location on the top housing member 108 that is prominent yet easy for a user to quickly access.

[0017] The legs 312 may be of any suitable height y 324, such as a height within the range of about 0.3 mm to about 0.7 mm. The light ring assembly 206 may be of any suitable height z 326, such as a height within the range of about 1.75 mm to about 2.25 mm. In addition, the light ring assembly 206 is recessed from a corner of the bottom housing member 110 by a distance x 328, which may include any suitable distance within the range of about 3.5 mm to about 4.25 mm. The recessed distance x 328 represents the difference between the radius of the light ring assembly 206 and the radius of the outer surface of the bottom housing member 110. The legs 312 are spaced from the light ring assembly 206 by a space equal to a distance q 330. The light ring assembly 206 is inserted from the outer surface by an amount equal to the distance q330. The distance q330 is any value within the range of about 1.25 mm to about 1.75 mm. The heights 324 and 326 and the insertion distances 328 and 33 The combination of 0 provides sufficient space below the housing 104 for the diffuse light provided by the light ring assembly 206 to radiate below the housing 104 and reflect at a particular intensity off the surface on which the range extender 102 rests.

[0018] FIG. 3C illustrates a right elevation 340 of the range extender 102. FIG. 3D illustrates a left elevation 350 of the range extender 102. In one aspect, the housing 104 has a height h 342 in the range of about 75 mm to about 90 mm. As shown, the range extender 102 is The privacy switch 116 has similar contours on the front and right sides. In one aspect, the privacy switch 116 may protrude outwardly from the vertical wall 202 of the upper housing member 108. Alternatively, the privacy switch 116 may be flush with the outer surface of the vertical wall 202 or may be recessed from the outer surface of the vertical wall 202.

[0019] 4 shows a top view 400 of the range extender 102. In the top view 400, the top end 304 of the upper housing member 108 is shown and is generally circular. The top end 304 includes a number of holes 114 that align with audio sensors (not shown) within the housing 104 that are configured to receive audio input from a user, such as a voice command. The top view 400 includes cut line 6-6, which corresponds to the cross-sectional view of FIG.

[0020] FIG. 5 shows a bottom view 500 of the range extender 102. The bottom housing member 110 includes a plurality of holes 202. The plurality of holes 202 may be arranged in any suitable pattern or arrangement on the bottom housing member 110. Here, the plurality of holes 202 are arranged in four rows along the rounded edge 308 of the bottom housing member 110. In addition, the legs 312 include recesses 502 (e.g., indentations, holes) that indicate the location of the cantilever members 504 that are hidden behind the legs 312 (as represented by the dotted lines) on the light ring assembly 206. The cantilever members 504 are formed in the light ring assembly 206 and connected to the light ring assembly 206 at a fulcrum. The cantilever members 504 are flush with the light ring assembly 206. The recesses 502 are aligned with the free ends of the cantilever members 504. The cantilever member 504 is bendable by a force applied to its free end (e.g., at the location of the recess 502 on the leg 312) and interacts with a reset mechanism (described below in connection with FIG. 10D ) on a circuit board assembly disposed within the housing 104. In one aspect, the cantilever member 504 functions as a reset button that a user can press to reset the range extender 102.

[0021] Figure 6 shows a cross-sectional view 600 of the range extender device 102 of Figure 4 taken in a horizontal cutting plane in the direction indicated by cutting line 6-6. The range extender device 102 includes various hardware components within a housing 104 in a compact assembly. For example, the range extender device 102 includes a heat sink assembly 602 that supports multiple antennas 604 mounted thereto. The heat sink assembly 602 is disposed within the housing 104 proximate to an inner surface of a vertical wall 302 of the upper housing member 108. Additionally, the antennas 604 are disposed proximate to (e.g., adjacent to) the inner surface of the vertical wall 302 within a tolerance distance of 2 mm.

[0022] The range extender device 102 also includes a number of printed circuit board assemblies (PCBAs), including a first PCBA 606, a second PCBA 608, and a third PCBA 610. The PCBA 606 is disposed proximate to and abuts the top end 304 of the upper housing member 108. As described further below, the PCBA 606 is coupled to one or more touch sensors 612, one or more light emitting components 614, and one or more audio sensors (not shown in FIG. 6, but described in connection with FIG. 12). The PCBA 606 is further described below in connection with FIG. 12. The PCBAs 606, 608, and 610 are each made of a metal, e.g., glass, such as FR4 material. The PCBA 606, 608, and 610 may be a printed circuit board (PCB) having multiple layers and / or electrical traces, plated through holes for through-hole components, and / or pads for surface mount components. At least one of the PCBA 606, 608, and 610 includes one or more components configurable to implement a virtual assistant capable of processing speech input from a user to identify a query or command and initiating a corresponding function, including providing a speech output responsive to the query or command.

[0023] A second PCBA 608 is disposed on the opposite side of the heat sink assembly 602 from the PCBA 606. In particular, the PCBA 608 is disposed between the heat sink assembly 602 and a speaker assembly 616. The speaker assembly 616 is disposed between the PCBA 608 and a third PCBA 610. The PCBA 610 is disposed between the speaker assembly 616 and the bottom housing member 110. Abutting the exterior of the bottom housing member 110 is a light ring assembly 206 including an annular light guide 618 and a reflector 620. The light ring assembly 206 abuts the legs 312.

[0024] The upper housing member 108 also includes a recess on the inner surface of the top end 304. The upper housing member 108 is formed from a partially translucent material (e.g., a polymer or thermoplastic) that allows light to pass through the material if the thickness of the material is below a threshold. For example, a light emitting component 614 (e.g., a light emitting diode (LED)) connected to the PCBA 606 can emit light into a recess on the inner surface of the upper housing member 108. Light passes through the upper housing member 108 at its translucent location based on the thickness of the upper housing member 108 being below a threshold at a location aligned with the light emitting component 614, such as between the recess and the outer surface of the top end 304. The light may correspond to an operational state or functionality of the range extender device 102. Any suitable location on the upper housing member 108 may be used to provide a status light.

[0025] The upper housing member 108 has a substantially uniform thickness at the top end 304 and the rounded edge 306. For example, the inner and outer surfaces of the rounded edge 306 and the top end 304 follow substantially the same curve. However, the vertical walls 302 of the upper housing member 108 may not include a uniform thickness because the inner surfaces of the vertical walls 302 have a substantially zero draft surface (e.g., a generally straight surface with zero taper), while the outer surfaces of the vertical walls 302 have a curvature. In one aspect, the zero draft surface is substantially parallel to the central axis 106 such that the angle between the central axis 106 and the zero draft surface is less than 5 degrees. This zero draft inner surface of the vertical walls 302 allows components within the housing to be slidably removable for easy disassembly and / or slidably insertable for easy assembly. A more detailed view of this aspect is shown in FIG. 7.

[0026] FIG. 7 shows an enlarged view 700 of a portion of the cross-sectional view 600 of FIG. 6 indicated by the dashed circle in FIG. 6, illustrating the connection point between the top housing member 108 and the bottom housing member 110 of the housing 104. In the enlarged view 700, the vertical wall 302 of the top housing member 108 is joined to the bottom housing member 110. As described above, the vertical wall 302 of the top housing member 108 includes a non-uniform thickness based on a zero-draft inner surface 702 and a curved outer surface 704. The curved outer surface 704 provides a smooth surface for the exterior appearance of the range extender 102, while the zero-draft inner surface 702 allows for easy insertion or removal of the internal components of the range extender 102. Also shown in the enlarged view 700 is a portion of the heat sink assembly 602 and a portion of the speaker assembly 616. The bottom housing member 110 includes a plurality of holes 202 (e.g., through holes) in the rounded edge 308, each hole 202 extending from the exterior of the bottom housing member 110 at the location of the respective hole 202. It is perpendicular to the surface.

[0027] The housing 104 includes a vertical step member 706 that connects the bottom housing member 110 to the vertical wall 302 of the top housing member 108. The vertical step member 706 is approximately 0. The central axis 106 of the housing 104 is located at a distance x708 in the range of 1 mm to about 0.3 mm. The vertical step member 706 is inserted toward the outer surface of the top housing member 108 and the bottom housing member 110 (offset from the outer surfaces of the top housing member 108 and the bottom housing member 110). The vertical step member 706 includes a height y710 in the range of about 0.1 mm to about 0.5 mm. The vertical step member 706 creates a horizontal gap (e.g., seam 112 in FIG. 1) between the outer surface of the top housing member 108 and the outer surface of the bottom housing member 110, the gap including a height equal to the height y710 of the vertical step member 706 and a depth equal to the distance x708 the vertical step member 706 is inserted. The resulting gap is substantially uniform from the user's perspective. Without the vertical step member 706, the connection between the top housing member 108 and the bottom housing member 110 may create a seam that is easily perceived by the human eye as being uneven in height. Thus, the gap created by the vertical step member 706 is less likely to be perceived by the user as being uneven.

[0028] FIG. 8 illustrates an example exploded view 800 of the range extender device 102. As shown generally in FIG. 8, a touch sensor 802 is disposed between the PCBA 606 and the upper housing member 108. In particular, the touch sensor 802 is disposed proximate to and in contact with an inner surface of the top end 304 of the upper housing member 108 to detect touch input to the top surface of the upper housing member 108. A heat sink assembly 602 is disposed between the PCBA 606 and the PCBA 608. Fasteners 804 may be used to secure the heat sink assembly 602 to the upper housing member 108. Any suitable fasteners, such as screws, bolts, rivets, etc., may be used. In certain aspects, a thermal interface material 806 (e.g., thermal gel, thermal pad, etc.) and an electromagnetic (EMI) gasket 808 are included between the heat sink assembly 602 and the PCBA 608.

[0029] The PCBA 608 is disposed between the heat sink assembly 602 and the speaker assembly 616. A privacy switch 116 is included proximate (e.g., adjacent) to the speaker assembly 616. A speaker mesh 810 is disposed adjacent to the bottom housing member 110 along the curved edge 308. In one aspect, the speaker mesh 810 is assembled to the bottom housing 110 with an adhesive on the speaker mesh 810. The speaker mesh 810 limits audio distortion and reduces resonance peaks in addition to reducing ingress of dust or liquid into the holes in the bottom housing member 110. Below the speaker assembly 616 is a PCBA 610 that includes one or more LEDs that emit light into the light ring assembly 206. The PCBA 610 may be attached to the bottom housing member 110 via a pressure sensitive adhesive (PSA) 812 or other adhesive, and / or one or more fasteners 813. Additional fasteners 814 may be used to secure the bottom housing member 110 to the speaker assembly 616 or to secure the bottom housing member 110 to the heat sink assembly 602 through holes in the speaker assembly 616.

[0030] Connected to the bottom exterior surface of the bottom housing member 110 is a light ring assembly 206 that includes an annular light guide 618, a reflector 620, a light isolator 816, and a layer of PSA 818. The light isolator 816 reflects light between the annular light guide 618 and the reflector 620, increasing the brightness of the light. The light isolator 816 has the same function as the reflector 620 and can be made from any suitable material, examples of which include white and black PET film. The reflector 620 can have channels or surfaces that are coated or lined with a reflective material to reflect the light emitted by the LEDs on the PCBA 610 back into the annular light guide 618. The light guide 618 diffuses the reflected light to provide an underglow below the housing 104. The PSA 818 bonds the reflector 620 to the annular light guide 618. The ring assembly 206 is disposed between the bottom housing member 110 and the legs 312. Fasteners 820 may be used to secure the light ring assembly 206 to the bottom housing member 110. The legs 312 may be adhered to the light ring assembly 206 using any suitable adhesive (not shown), such as PSA.

[0031] 9 shows a top view 900 and a bottom view 910 of the PCBA 606 of FIG. 8, respectively. The PCBA 606 includes a light-emitting component 902, such as an LED. The light-emitting component 902 is aligned with a recess in the inner surface of the top end 304 of the housing 104 and emits light through the housing 104. As the light is emitted through the housing 104, the color of the light seen by the user is based on the material and paint color of the housing 104. The light-emitting component 902 can be calibrated to emit light based on the state or function of the range extender device 102. Alternatively, the light-emitting component 902 can emit light to indicate the location of a touch-sensitive area on the housing 104.

[0032] The PCBA 606 also includes a number of audio sensors 912, such as microphones. In the illustrated example, the PCBA 606 includes three audio sensors 912. Each audio sensor 912 is aligned with a hole 114 in the upper housing member 108. The PCBA 606 also includes a touch integrated circuit (IC) chip 914 that maps touch input detected by the touch sensors 802 to a specific function. For example, the touch input may correspond to volume up, volume down, play, pause, next, skip, resume, previous track, etc.
