[0012] The detailed description set forth below is intended as an illustration of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The accompanying drawings are incorporated into this specification and constitute a part of the detailed description. The detailed description includes specific details to provide a thorough understanding of the subject technology. However, it will be clear and apparent to those skilled in the art that the subject technology is not limited to the specific details set forth herein and may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring the concepts of the subject technology.

[0013] Head-mountable devices (HMDs), such as head-worn displays, headsets, visors, smart glasses, and head-up displays, can perform a variety of functions determined by the components (e.g., sensors, circuitry, and other hardware) included in the HMD during manufacture. For example, an HMD with virtual reality capabilities can replace a natural, real-life environment with virtual content. In another example, an HMD with augmented or mixed reality capabilities allows a user to view certain computer-generated images superimposed on a natural, real-life environment. A band can be attached to the HMD to fit and maintain the HMD on the user's head.

[0014] The subject technology is directed to modifications to the band that facilitate securing / coupling the band to an HMD as well as detaching the band from the HMD. The bands described herein may include an opening that receives a pin or connector from the HMD. To retain the pin within the opening and secure the band to the HMD, the band includes a latch body. The latch body may remain secured within the pin based on one or more springs that bias the latch body within the pin. The band further includes a tab or pull tab designed to actuate the latch body outward from the pin. For example, a user can grasp and pull the tab. When force applied by the user overcomes the biasing force provided by the spring(s), the latch body is detached from the pin, allowing the band to be separated from the HMD.

[0015] To facilitate the mobility of the latch body, the tab can be secured with a bar (or multiple bars). At least one of the bars can act as a pulley, so that the pulley helps actuate the latch body when the tab is pulled. Furthermore, the use of a pulley can allow for different displacements of the tab and the latch body. For example, the tab can move 2 millimeters (mm), but the latch body can move 1 mm and still be detached from the pin of the HMD. The different displacements between the latch body and the tab can improve the user experience interacting with the band.

[0016] These and other embodiments are described below with reference to Figures 1-8. However, those skilled in the art will readily appreciate that the detailed description provided herein with respect to these figures is for illustrative purposes only and should not be construed as limiting.

[0017] According to some embodiments, as shown in FIG. 1 , the system 100a may include a head-wearable device 102 including a frame 104 and a band 106 designed to couple / secure to the frame 104. The frame 104 may be positioned in front of a user's eyes to provide information within the user's field of view. The frame 104 may be provided with nose pads or another mechanism for resting on the user's nose. The frame 104 further includes one or more displays 108 (e.g., one for each eye). The head-wearable device 102 may include a camera 110 for capturing a view of an environment external to the head-wearable device 102. The one or more displays 108 may provide visual (e.g., image or video) output based on the view captured by the camera 110. For example, the one or more displays 108 may transmit light from the camera 110 for the user to view based on the physical environment. The one or more displays 108 may include lens-like optical properties for vision correction based on incident light from the physical environment. Additionally or alternatively, one or more displays 108 may provide information as a display within the user's field of view. The displayed information may be provided to exclude the view of the physical environment or in addition to (e.g., superimposed on) the physical environment.

[0018] The frame 104 and / or band 106 may serve to surround the peripheral region of the head-wearable device 102 and support any internal components in their assembled position. For example, the frame 104 may surround and support various internal components (including, for example, integrated circuit chips, processors, sensors, input / output devices, memory devices, and other circuitry) to provide computing and functional operations for the head-wearable device 102.

[0019] The head wearable device 102 and the band 106 may include mechanisms and modifications for securing and detaching them from one another. For example, the head wearable device 102 includes pins 112a and 112b that may be inserted into openings 114a and 114b, respectively, of the band 106, thus allowing the band 106 to be secured to the head wearable device 102. To remove the band 106 from the head wearable device 102, the band 106 includes tabs 116a and 116b. A force (e.g., a pulling force) applied to the tab 116a releases the pin 112a from the opening 114a, and similarly, a force applied to the tab 116b releases the pin 112b from the opening 114b. Thus, pulling on the tabs 116a and 116b results in the band 106 being detached from the head wearable device 102, as further shown and described below.

[0020] 2, system 100b includes head-wearable device 102 designed to secure to an alternative component. For example, intermediate bands 118a and 118b can be secured to head-wearable device 102. As shown, intermediate bands 118a and 118b include openings 120a and 120b, respectively, that are securable with pins 112a and 112b, respectively, of head-wearable device 102. Intermediate bands 118a and 118b also include tabs 122a and 122b, respectively. Force applied to tabs 122a and 122b causes pins 112a and 112b to release from openings 120a and 120b, respectively.

[0021] Additionally, intermediate bands 118a and 118b can be secured to band 126, which is used to wrap around a user's head. As shown, intermediate bands 118a and 118b include pins 128a and 128b, respectively. Band 126 includes openings 130a and 130b that can receive pins 128a and 128b of intermediate band 118a and 118b, respectively.

[0022] The intermediate bands 118a and 118b can accommodate several features. For example, the intermediate bands 118a and 118b may include audio assemblies 132a and 132b, respectively. The audio assemblies 132a and 132b may each include a speaker module designed to generate sound waves (e.g., acoustic energy) based on one or more signals and commands from the head-wearable device 102. Additionally or alternatively, the audio assemblies 132a and 132b may each include a microphone designed to convert received audio signals (e.g., from a user or the environment) into electrical signals that are provided to the head-wearable device 102. The intermediate bands 118a and 118b may also each include a power source 134a and a power source 134b, respectively. The power sources 134a and 134b can provide power to the audio assemblies 132a and 132b, respectively. Additionally, the power sources 134a and 134b can provide an alternative power source for the head-wearable device 102.

[0023] Referring to FIG. 3 , band 206 is designed to be secured to a head-wearable device. Band 206 may take the form of band 106 ( FIG. 1 ) or may take the form of intermediate band 118 a, intermediate band 118 b, and band 126 (shown in FIG. 2 ). As shown, band 206 includes a strap 236 that acts as a main body or band body used to carry several components. For example, band 206 includes an opening 214 formed in strap 236. Opening 214 represents a through-hole in strap 236 and is used to receive a pin or connector of the head-wearable device (not shown in FIG. 3 ). As shown, opening 214 includes a tablet or pill shape; however, other shapes are possible. For example, opening 214 can generally be shaped to correspond to the shape of a pin so that opening 214 can receive the pin.

[0024] Band 206 also includes a latch body 238 housed within strap 236. As shown, latch body 238 extends at least partially into opening 214. To actuate latch body 238 to move out or at least partially out of opening 214, band 206 includes tab 216. Tab 216 may include, by way of non-limiting example, multiple structures (e.g., thread, polymer strands) woven together. Tab 216 can be displaced or pulled, and the displacement of tab 216 causes actuation of latch body 238 to move at least partially out of opening 214. When the force displacing tab 216 is removed, tab 216 returns to its original position and latch body 238 returns to its position within opening 214.

[0025] Band 206 further includes a ring 240 that extends along opening 214. Furthermore, ring 240 extends into opening 214. In this manner, ring 240 engages with the pin when the pin is inserted into opening 214. Advantageously, ring 240 effectively closes or blocks the gap between strap 236 and the pin at opening 214, thus limiting or preventing objects, such as the user's hair, from entering opening 214. Band 206 also includes a cap 242 that covers several components housed in strap 236.

[0026] Referring to FIG. 4, ring 240 follows the general shape of opening 214. Cap 242 (shown in FIG. 3) has been removed to show additional features. For example, band 206 includes springs 244a and 244b carried within strap 236. Springs 244a and 244b are connected to latch body 238 and each act as a biasing element that biases latch body 238 toward opening 214 so that a portion of latch body 238 extends through opening 214. Also shown in FIG. 4, tab 216 is between springs 244a and 244b.

[0027] Band 206 further includes bar 246a and bar 246b. Bar 246a is engaged with latch body 238 and extends at least partially through the latch body. Bar 246a may function as a pulley during user interaction with tab 216. In this manner, bar 246a facilitates actuation of latch body 238 based on a force (e.g., a pulling force) applied to tab 216, as will be described below. Tab 216 is also secured to strap 236 by wrapping around and engaging bar 246b. Band 206 may include a stationary frame 248 or other stationary object located within strap 236 that holds bar 246b stationary / fixed.

[0028] 5, spring 244a (and spring 244b shown in FIG. 4) provides a biasing or spring force that maintains latch body 238 within opening 214. Tab 216 wraps around bar 246a and terminates in and is connected to bar 246b, which is held in place by stationary frame 248. Tab 216 also extends through opening 250 formed in strap 236. Thus, tab 216 is partially within strap 236 and partially outside of strap 236.

[0029] The opening 214 may include a tapered surface 252. In this manner, the opening 214 may include a tapered opening having a surface opening 254a and a surface opening 254b, where the diameter of the surface opening 254a is smaller than the diameter of the surface opening 254b. In other words, the diameter of the surface opening 254b is larger than the diameter of the surface opening 254a. Additionally, the ring 240 is positioned between the surface opening 254a and the latch body 238. However, other locations are possible, such as between the surface opening 254b and the latch body 238.

[0030] Referring to FIG. 6 , a head-wearable device 202 is connected to a band 206. As shown, the head-wearable device 202 includes a pin 212 positioned within an opening 214. As shown, the pin 212 includes a cavity 254 that receives a latch body 238. When the latch body 238 is positioned within the cavity 254, the pin 212 is secured within the opening 214, and the head-wearable device 202 and the band 206 are secured together. To facilitate the process, the latch body 238 may include a chamfered surface 256 that serves as an initial engagement surface between the pin 212 and the latch body 238. As shown, the chamfered surface 256 faces or is oriented toward a surface opening of the strap 236 that initially receives the pin 212 (e.g., surface opening 254b in FIG. 5 ). Furthermore, when the pin 212 is inserted into the opening 214, it engages the ring 240, thus closing the gap between the pin 212 and the strap 236.

[0031] While it may be desirable for the pin 212 to remain within the opening 214, it is generally undesirable for the pin 212 to become stuck or seized within the opening 214. Advantageously, the tapered surface 252 of the opening 214 not only provides additional space / volume for the pin 212 to enter the opening 214, but also prevents undesirable binding or snagging between the pin 212 and the strap 236 at the opening 214.

[0032] To mitigate undesired wobble or movement between the head wearable device 202 and the band 206, the head wearable device 202 may include a ring 258 connected to the pin 212. The ring 258 is designed to at least partially fit into the gap between the pin 212 and the strap 236, as shown in FIG. 6 . The ring 258 may include compressible material(s) (e.g., rubber). In this manner, the ring 258 compresses and conforms to the shape of the gap, thus reducing or preventing wobble of the head wearable device 202 and / or the band 206. The ring 258 therefore mitigates various tolerance issues associated with the tapered surface 252 and / or the pin 212 and / or the opening 214. In some embodiments (not shown in FIG. 6 ), the pin 212 includes a tapered surface and the opening 214 does not include a tapered surface.

[0033] 5 and 6 show the latched position in which the latch body 238 enters the pin 212, thus securing the band 206 to the head wearable device 202.

[0034] 7, a force applied to tab 216 in the direction of arrow 260 displaces tab 216 and simultaneously displaces latch body 238. As a result, latch body 238 is disengaged from cavity 254 in pin 212, causing pin 212 to withdraw from opening 214. The force applied to tab 216 overcomes the biasing force provided by spring 244a (and spring 244b shown in FIG. 4). As shown, latch body 238 is actuated and disengaged, or at least partially disengaged, from opening 214. Thus, FIG. 7 illustrates a latched position in which band 206 can be removed from head-wearable device 202.

[0035] Due in part to tab 216 being wrapped around bar 246a and bar 246a being connected to latch body 238, a force applied to tab 216 that actuates latch body 238 also actuates bar 246a, causing bar 246a to move relative to and toward bar 246b. Also, based on tab 216 being wrapped around bar 246a, the displacement of tab 216 can differ from the displacement of latch body 238. For example, when tab 216 is displaced by distance 262a, latch body 238 is displaced by distance 262b, which is different from distance 262a. As shown, distance 262b is less than distance 262a. In some embodiments, distance 262b is one-half or approximately one-half of distance 262a. It should be noted that when the force applied to tab 216 is released, latch body 238 is actuated by springs 244a and 244b such that latch body 238 moves toward and seats within opening 214.

[0036] Referring to FIG. 8 , a head-wearable device 302 is connected to a band 306. As shown, the head-wearable device 302 includes a pin 312 that is positioned within an opening 314. As shown, the pin 312 includes a cavity 354 that receives a latch body 338. When the latch body 338 is positioned within the cavity 354, the pin 312 is secured within the opening 314, and the head-wearable device 302 and the band 306 are secured together. To facilitate the process, the latch body 338 may include a chamfered surface 356 that serves as an initial engagement surface between the pin 312 and the latch body 338. As shown, the chamfered surface 356 faces or is oriented toward the surface opening of the strap 336 that initially receives the pin 312. Furthermore, when the pin 312 is inserted into the opening 314, it engages the ring 340, thus closing the gap between the pin 312 and the strap 336. Opening 314 may include a tapered surface 352 to allow pin 312 to enter opening 314 and provide additional space / volume for bonding or undesired locking between pin 312 and strap 336 at opening 314. Also, while previous examples of head wearable devices may include a ring (e.g., head wearable device 202 with ring 258 shown in FIG. 6), head wearable device 302 does not include a ring.

[0037] Figures 3-8 show and describe the connection mechanism for one end of the band. However, it should be noted that the band shown in Figures 3-8 includes an additional, opposing end that may include any of the connection mechanisms for that end shown and described in Figures 3-8.
