[0004] This application provides a wearable device and its wearing component to solve the problem that resonance easily occurs when smart glasses emit sound, causing discomfort to the user.

[0005] To solve the above-mentioned technical problems, this application adopts a technical solution as follows: providing a wearable device. The wearable device includes: a housing, including a recessed section, the top wall of the recessed section forming a downward recess in the wearing state, and the bottom wall of the recessed section having a first sound outlet and a second sound outlet, the first sound outlet being disposed corresponding to the bottom of the recess; a speaker, disposed in the recessed section, and cooperating with a first side wall of the housing to form a resonant cavity; wherein, the first sound outlet and the second sound outlet are both connected to the resonant cavity, the first sound outlet and the second sound outlet are located opposite each other on adjacent sides of the resonant cavity, the first sound outlet and the second sound outlet are both used for sound emission, and the second sound outlet is also used to increase the resonant frequency of the resonant cavity.

[0006] In some embodiments, the resonant cavity has a rectangular cross-section perpendicular to the spacing direction of the sidewalls of the speaker and the housing, and the first sound outlet and the second sound outlet are located on adjacent first and second sides of the rectangle.

[0007] In some embodiments, the ratio of the length of the second sound hole along the extension direction of the second side to the length of the second side is greater than or equal to 0.1 and less than or equal to 0.7.

[0008] In some embodiments, the second sound hole extends from one end of the second side adjacent to the first side to the other end of the second side away from the first side;

[0009] Wherein, the first side is the short side of the rectangle, and the second side is the long side of the rectangle.

[0010] In some embodiments, the second sound outlet and the first sound outlet are spaced apart on the bottom wall; or the second sound outlet and the first sound outlet are connected on the bottom wall. In some embodiments, the recessed section includes a first bent portion and a second bent portion that are bent and connected, the top surfaces of the second bent portion and the first bent portion cooperate to form the recess, and the speaker is disposed in the second bent portion;

[0011] The bottom wall of the recessed section includes a first bottom surface, a second bottom surface, and a third bottom surface that are bent and connected in sequence. The first bottom surface is located at the first bend, the second bottom surface and the third bottom surface are located at the second bend, the first sound outlet is disposed on the second bottom surface, and the second sound outlet is disposed on the third bottom surface.

[0012] In some embodiments, the first sidewall faces the user's head when worn, and the side of the speaker facing away from the resonant cavity is attached to the second sidewall of the recessed section.

The second sound outlet also effectively shortens the cavity length of the resonant cavity to increase its resonant frequency. This makes the frequency response curve of the speaker as flat as possible, thus avoiding discomfort caused by resonance of the resonant cavity during sound generation. Furthermore, the speaker is located in a recessed section, and the bottom wall of the recessed section has a first sound outlet, which allows the first sound outlet to be closer to the ear canal opening when worn, thus improving the user's listening quality.

[0031] This application provides a wearable device 100, in conjunction with reference to [reference needed]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an embodiment of the wearable device provided in this application. Figure 2 yes Figure 1 The diagram shows the exploded structure of the wearable device.

[0032] Wearable device 100 may include glasses, smart bracelets, headphones, hearing aids, smart helmets, smartwatches, smart clothing, smart backpacks, smart accessories, or any combination thereof.

Wearable device 100 may also be a head-mounted device such as a helmet, augmented reality (AR) device, or virtual reality (VR) device.

[0033] In some embodiments, augmented reality (AR) devices or virtual reality (VR) devices may include virtual reality headsets, virtual reality glasses, augmented reality headsets, augmented reality glasses, etc., or any combination thereof. For example, VR devices and / or VR devices may include Google Glass, Oculus Rift, HoloLens, Gear VR, etc.

[0034] The wearable device 100 includes a viewing element 10, a quick-release assembly 20, and a wearing element 30. The viewing element 10 and the wearing element 30 are respectively connected to both ends of the quick-release assembly 20, and both the viewing element 10 and the wearing element 30 can be quickly detached from the quick-release assembly 20. The wearing element 30 can also be configured with the quick-release assembly 20 as a conventional connection structure or an integrated structure.

[0035] In this embodiment, the wearable device 100 is a head-mounted device, and the viewing component 10 can be a lens, a display screen, or a display screen that functions as a lens. The viewing component 10 can also be a lens and its auxiliary components or a display screen and its auxiliary components. The auxiliary components can be a frame or frame, etc., so as to facilitate its interconnection with the quick-release assembly 20.

[0036] Alternatively, the viewing element 10 can also be a dial structure with display function.

[0037] In this embodiment, the wearable device 100 is a pair of glasses, the visible component 10 is the frame, and the wearing component 30 is the temple. The wearable device 100 includes a visible component 10, two sets of quick-release components 20 and two sets of wearing components 30. The two sets of quick-release components 20 are disposed at both ends of the visible component 10, and the two sets of wearing components 30 are respectively connected to the corresponding set of quick-release components 20.

[0038] Optionally, the wearing piece 30 can also be a headband or watch strap, etc. Both ends of the wearing piece 30 can be connected to a set of corresponding quick-release components 20 respectively. Alternatively, one end of the wearing piece 30 can be connected to a set of quick-release components 20, and the other end can be directly connected to the viewing piece 10.

[0039] In other embodiments, the wearable device 100 may also not include the quick-release assembly 20, so that the two ends of the viewing member 10 are connected to the wearing member 30.

[0040] In other words, the wearable device 30 can be directly connected to the visual device 10 or indirectly connected to the visual device 10 through the quick-release assembly 20.

[0041] See also Figures 3 to 6 ,in Figure 3 yes Figure 2 The diagram shows the axial side structure of the wearable component in the wearable device. Figure 4 yes Figure 3 The diagram shows another axial side structure of the wearable device. Figure 5 yes Figure 3 Another axial side view of the wearable device is shown. Figure 6 yes Figure 3 The diagram shows an exploded view of the wearable device.

[0042] The wearable device 30 includes a housing 31 and a speaker 32. The housing 31 includes a recessed section 312. The top wall 315 of the recessed section 312 forms a downward recess 314 in the wearing state. The bottom wall 316 of the recessed section 312 is provided with a first sound outlet 301 and a second sound outlet 302. The first sound outlet 301 is located at the bottom of the recess 314. The speaker 32 is disposed in the recessed section 312 and cooperates with the first side wall 317 of the housing 31 to form a resonant cavity 303. The two sides of the first side wall 317 are respectively connected to the top wall 315 and the bottom wall 316. The first sound outlet 301 and the second sound outlet 302 are both connected to the resonant cavity 303. The first sound outlet 301 and the second sound outlet 302 are located opposite each other on adjacent sides of the resonant cavity 303. The first sound outlet 301 and the second sound outlet 302 are both used to emit sound. The second sound outlet 302 is also used to increase the resonant frequency of the resonant cavity 303.

[0043] In this embodiment, the housing 31 further includes a first connecting segment 311 and a second connecting segment 313. The first connecting segment 311, the recessed segment 312 and the second connecting segment 313 are connected in sequence. The end of the first connecting segment 311 away from the recessed segment 312 is hinged to the quick-release assembly 20, and the second connecting segment 313 is used to be mounted on the user's ear.

[0044] Optionally, the housing 31 may also include a plurality of recessed sections 312, and at least one of the recessed sections 312 may be used to be mounted on the user's auricle, and the recessed section 312 adjacent to the quick-release component 20 may also be hinged to the quick-release component 20; or, the housing 31 may include the recessed section 312 as described above and the second connecting section 313, and the end of the recessed section 312 away from the second connecting section 313 may be hinged to the quick-release component 20.

[0045] Furthermore, taking the scenario of a user wearing the wearable device 100 as an example, in the wearing state, the concave section 312 forms a downward recess 314, that is, the concave section 312 extends towards the ear canal opening, so that the first sound outlet 301 and the second sound outlet 302 provided in the concave section 312 are close to the ear canal opening, which is conducive to transmitting sound to the user.

[0046] In this embodiment, as Figure 3 As shown, the recessed section 312 includes a first bent portion 3121 and a second bent portion 3122 connected by a bend. The speaker 32 is disposed in the second bent portion 3122. The top walls 315 of the first bent portion 3121 and the second bent portion 3122 cooperate with each other to form a recess 314. In other words, the recess 314 is approximately V-shaped. A first connecting section 311 is connected to the end of the first bent portion 3121 away from the second bent portion 3122, and a second connecting section 313 is connected to the end of the second bent portion 3122 away from the first bent portion 3121.

[0047] The bending connection can be understood as the first bending part 3121 and the second bending part 3122 extending in different directions, or the first bending part 3121 and the second bending part 3122 being set at an angle.

[0048] It should be noted that the top wall 315 of the first bending portion 3121 and the second bending portion 3122 referred to in this article refers to the portion of the top wall 315 of the wearer 30 located on the first bending portion 3121 and the second bending portion 3122, respectively.

[0049] Optionally, the recessed section 312 may also be U-shaped or W-shaped, etc., and this application does not specifically limit it.

[0050] like Figure 4 As shown, the housing 31 also includes a second sidewall 318 opposite to the first sidewall 317. The first sidewall 317, the top wall 315, the second sidewall 318 and the bottom wall 316 constitute the housing 31.

[0051] like Figure 5 As shown, the top wall 315 includes a first top surface 3151 located in the first bend 3121 and a second top surface 3152 located in the second bend 3122, and the first top surface 3151 and the second top surface 3152 constitute the recess 314.

[0052] The bottom wall 316 includes a first bottom surface 3161, a second bottom surface 3162 and a third bottom surface 3163 that are bent and connected in sequence. The first bottom surface 3161 is located in the first bending portion 3121, and the second bottom surface 3162 and the third bottom surface 3163 are located in the second bending portion 3122.

[0053] By setting a second sound outlet 302 connected to the first sound outlet 301 of the resonant cavity 303, and with the first sound outlet 301 and the second sound outlet 302 located on adjacent sides of the resonant cavity 303, both the first sound outlet 301 and the second sound outlet 302 can be used to produce sound. The second sound outlet 302 can also be used to shorten the cavity length of the resonant cavity 303 to increase the resonant frequency of the resonant cavity 303. This makes the frequency response curve of the speaker 32 as flat as possible, avoiding discomfort caused by resonance of the resonant cavity 303 when the user wears it.

[0054] Specifically, if the recessed section 312 only has a first sound outlet 301 connected to the resonant cavity 303, then the resonant cavity 303 is equivalent to being open at one end and closed at the other. When the cavity length of the resonant cavity 303 is equal to one-quarter of the sound wave wavelength, the resonant cavity 303 generates a resonance peak. This resonance peak can easily cause discomfort to the user when wearing the wearable device 100. Therefore, it is necessary to move the resonant frequency of the resonant cavity 303 to a higher level. The higher the frequency, the shorter the wavelength, which means that the cavity length should be as short as possible. Therefore, by opening a second sound outlet 302 on one side of the cavity length, the cavity length of the resonant cavity 303 can be effectively shortened, thereby increasing the resonant frequency of the resonant cavity 303. In other words, in this application, the side where the second sound outlet 302 is located is the side of the resonant cavity 303 with cavity length.

[0055] Specifically, the first sound outlet 301 is disposed on the second bottom surface 3162, and the second sound outlet 302 is disposed on the third bottom surface 3163.

[0056] See also Figure 5 and Figure 7 ,in Figure 7 yes Figure 3 The diagram shows a cross-sectional view of the wearable device.

[0057] In this embodiment, the loudspeaker 32, the first sidewall 317, the top wall 315, and the bottom wall 316 surround and form the resonant cavity 303. The first sound outlet 301 is disposed on the second bottom surface 3162 of the bottom wall 316, and the second sound outlet 302 is disposed on the third bottom surface 3163 of the bottom wall 316. The second sound outlet 302 has the effect of effectively shortening the cavity length of the resonant cavity 303, thereby increasing the resonant frequency of the resonant cavity 303.

[0058] See Figure 8 , Figure 8 yes Figure 7 The diagram shows three cross-sectional structures of the resonant cavity in the wearable device.

[0059] like Figure 7 and Figure 8As shown, the resonant cavity 303 has a rectangular cross-section perpendicular to the spacing direction of the first sidewall 317 of the speaker 32 and the housing 31. The rectangular cross-section of the resonant cavity 303 can be a rectangle, a square, a parallelogram, or a trapezoid, etc. The first sound outlet 301 and the second sound outlet 302 are respectively located on the adjacent first sidewall 3031 and the second sidewall 3032 of the rectangle. Thus, the second sound outlet 302 can effectively shorten the cavity length of the resonant cavity 303 along the extension direction of the second sidewall 3032, thereby increasing the resonant frequency of the resonant cavity 303.

[0060] In this embodiment, the rectangular cross-section of the resonant cavity 303 is rectangular, the first side 3031 is the short side of the rectangle, the second side 3032 is the long side of the rectangle, and the second sound outlet 302 can effectively shorten the cavity length of the resonant cavity 303 along the long side of the rectangle.

[0061] Furthermore, the second sound outlet 302 extends from one end of the second side 3032 near the first side 3031 to the other end of the second side 3032 away from the first side 3031, which can simultaneously shorten the cavity length of the resonant cavity 303 and enhance the sound output effect of the first sound outlet 301.

[0062] Optionally, the second sound outlet 302 can also be located in the middle of the second side 3032.

[0063] Furthermore, the ratio of the length of the second sound outlet 302 along the extension direction of the second side 3032 to the length of the second side 3032 is greater than or equal to 0.1 and less than or equal to 0.7. A ratio greater than or equal to 0.1 can effectively increase the resonant frequency of the resonant cavity 303, while a ratio less than or equal to 0.7 can prevent the strength or stiffness of the second bend 3122 from being weakened too much. Therefore, a ratio greater than or equal to 0.1 and less than or equal to 0.7 can significantly improve the resonant frequency of the resonant cavity 303 while ensuring that the strength or stiffness of the second bend 3122 still meets the standards.

[0064] For example, see references. Figure 8 and Figure 9 ,in Figure 9 yes Figure 8 Schematic diagram of the frequency response curves corresponding to the three resonant cavity structures.

[0065] Figure 8 The resonant cavity 303 shown in (a) does not have a second sound outlet 302, which corresponds to Figure 9 The resonant frequency of the intermediate resonant cavity 303 is around 3.4kHz; Figure 8 When the ratio of the length of the second sound outlet 302 along the extension direction of the second side 3032 to the length of the second side 3032 shown in (b) is 0.3, it corresponds to Figure 9 The resonant frequency of the intermediate resonant cavity 303 is increased to 4.4kHz; Figure 8 When the ratio of the length of the second sound outlet 302 along the extension direction of the second side 3032 to the length of the second side 3032 shown in (c) is 0.6, it corresponds to Figure 9 The resonant frequency of the middle resonant cavity 303 is increased to 6.0kHz; it can be seen that the setting of the second sound outlet 302 can significantly improve the resonant frequency of the resonant cavity 303.

[0066] The ratio of the length of the second sound hole 302 along the extension direction of the second side 3032 to the length of the second side 3032 can also be 0.1, 0.15, 0.2, 0.25, 0.35, 0.4, 0.5 or 0.7, etc.

[0067] In this embodiment, the second sound outlet 302 and the first sound outlet 301 are spaced apart on the bottom wall 316. That is, there is a prism separating the second sound outlet 302 and the first sound outlet 301 on the bottom wall 316. The prism between the second sound outlet 302 and the first sound outlet 301 can strengthen the bottom wall 316 and reduce the risk of deformation of the first side wall 317 and the second side wall 318.

[0068] In other embodiments, the second sound outlet 302 and the first sound outlet 301 can also be physically connected, that is, on the bottom wall 316, the second sound outlet 302 and the first sound outlet 301 are equivalent to being connected to form a through hole, and are located on adjacent sides of the resonant cavity 303.

[0069] See also Figure 5 and Figure 6 When worn, the first sidewall 317 faces the user's head, and the side of the speaker 32 away from the resonant cavity 303 is attached to the second sidewall 318 of the recessed section 312 to reduce the thickness of the recessed section 312 in the direction from the first sidewall 317 to the second sidewall 318.

[0070] Furthermore, the second sidewall 318 is also provided with a silencing hole 304, which is located in the second bend 3122. The speaker 32 covers the silencing hole 304, and the silencing hole 304, together with the first sound outlet 301 and the second sound outlet 302, forms a dipole. The noise-canceling hole 304, the first sound outlet hole 301, and the second sound outlet hole 302 are all located on different sides of the speaker 32. When worn, the distances from the noise-canceling hole 304, the first sound outlet hole 301, and the second sound outlet hole 302 to the user's ear canal are also different. The sound output from the noise-canceling hole 304 and the sound output from the first sound outlet hole 301 and the second sound outlet hole 302 meet specific conditions (e.g., a phase difference of about 180 degrees) and can form a dipole-like radiation. In the far field, the sound output from the noise-canceling hole 304 and the sound output from the first sound outlet hole 301 and the second sound outlet hole 302 can cancel each other out of phase, thereby reducing the sound leakage volume of the speaker 32 in the far field and preventing the sound output from the speaker 32 from being heard by people nearby, thus making the wearable device 30 more private.

[0071] like Figure 3 and Figure 6 As shown, a first pickup hole 305 is provided at the recess 314, and the wearable piece 30 also includes a first pickup element 33. The first pickup element 33 is disposed at the first bend 3121 and is used to pick up sound through the first pickup hole 305.

[0072] In this embodiment, the first pickup hole 305 is located at the bottom of the recess 314. Since the bottom area of ​​the recess 314 is least affected by the wind speed outside the recess 314, the wind noise of the sound input by the first pickup hole 305 located here is minimal.

[0073] When a user is cycling or running, the wind speed outside the recess 314 is relatively high, while the airflow inside the recess 314 is less affected by the airflow outside the recess 314 due to the obstruction of the recessed section 312. Therefore, by setting the first pickup hole 305 at the recess 314, the wind noise of the sound obtained at the initial stage of the first pickup hole 305 is relatively small, which is beneficial to improving the quality of the obtained sound.

[0074] Optionally, the first pickup hole 305 may also be located in the waist of the recess 314.

[0075] Continue reading Figure 3 and Figure 6 The recessed section 312 is also provided with a second pickup hole 306, which is located on the second side wall 318; the wearable piece 30 also includes a second pickup member 37, which is disposed in the second bend portion 3122 of the recessed section 312 and located on the side of the speaker 32 away from the end of the first bend portion 3121. The second pickup member picks up sound through the second pickup hole.

[0076] The second pickup hole 306 is oriented differently from the first pickup hole 305, so as to obtain ambient noise through the second pickup hole 306. The sound obtained through the first pickup hole 305 and the second pickup hole 306 is then denoised by an algorithm to remove ambient noise.

[0077] The wearable device 30 also includes a circuit board 38 and a battery 39. The circuit board 38 is disposed inside the housing 31, and the battery 39 is disposed in the first connection section 311. The battery 39, the controller, the first pickup element 33, the second pickup element 37 and the speaker 32 are all electrically connected to the circuit board 38.

[0078] Unlike existing technologies, this application discloses a wearable device and its wearing component. By setting a second sound outlet and a first sound outlet connecting the resonant cavity, with the first and second sound outlets located opposite each other on adjacent sides of the resonant cavity, the first sound outlet is used for sound emission, and the second sound outlet is used to shorten the cavity length of the resonant cavity to increase the resonant frequency of the resonant cavity. This makes the frequency response curve of the speaker as flat as possible, avoiding discomfort caused by resonance of the resonant cavity during sound emission. Furthermore, the speaker is located in a recessed section, and the bottom wall of the recessed section has the first sound outlet, which allows the first sound outlet to be closer to the ear canal opening when worn, thus improving the user's listening quality.

[0079] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
