Technical Field

[0001] This application relates to the field of wearable device technology, and in particular to a wearable device and its wearable component. Background Technology

[0002] With the release of Google Glass by Google in 2012, the concept of wearable devices such as smart glasses became familiar to the public. Today, more mature wearable devices include smartwatches, VR / AR headsets, and smart glasses.

[0003] Smart glasses often have sound output capabilities. However, due to various reasons, smart glasses often have a low resonant frequency, which makes them prone to resonance when outputting sound, causing discomfort for users. Summary of the Invention

[0004] This application mainly 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, one technical solution adopted in this application is to provide a wearable device. The wearable device includes: a housing with a recessed section forming a downward indentation in the wearing state, the recessed section having a first sound outlet; a speaker disposed in the recessed section and forming a resonant cavity between the speaker and a side wall of the housing, the first sound outlet communicating with the resonant cavity; wherein, in the spacing direction between the speaker and the side wall of the housing, the thickness of the resonant cavity at the end near the first sound outlet is greater than the thickness of the resonant cavity at the end away from the first sound outlet.

[0006] In some embodiments, the thickness of the resonant cavity gradually decreases in the direction from the end near the first sound hole to the end away from the first sound hole.

[0007] In some embodiments, the wearable device includes a shield disposed between the speaker and the sidewall of the housing, and cooperating with the speaker to form a resonant cavity;

[0008] Wherein, the distance between the end of the shield near the first sound outlet and the diaphragm plane of the speaker is greater than the distance between the end of the shield away from the first sound outlet and the diaphragm plane of the speaker.

[0009] In some embodiments, the shield includes a first cover and a second cover connected together, the distance between the first cover and the diaphragm plane of the speaker is greater than the distance between the second cover and the diaphragm plane of the speaker, and the first cover is disposed adjacent to the first sound outlet.

[0010] In some embodiments, the first cover has a first plane facing the speaker, and the second cover has a second plane facing the speaker, the first plane and the second plane being parallel to the diaphragm plane of the speaker, respectively.

[0011] In some embodiments, the shield further includes a third shield connected between the first shield and the second shield, the third shield having a transition surface facing the speaker, two opposite sides of the transition surface connecting the first plane and the second plane respectively, and the distance between the transition surface and the diaphragm plane of the speaker gradually decreasing from the first plane to the second plane.

[0012] In some embodiments, the loudspeaker directly engages with the sidewall of the housing to form the resonant cavity, and the distance between the end of the sidewall of the housing near the first sound outlet and the diaphragm plane of the loudspeaker is greater than the distance between the end of the sidewall of the housing away from the first sound outlet and the diaphragm plane of the loudspeaker.

[0013] In some embodiments, the recessed section is further provided with a second sound outlet, the second sound outlet being connected to the resonant cavity, and the first sound outlet and the second sound outlet being located opposite each other on adjacent sides of the resonant cavity.

[0014] In some embodiments, the recessed section includes a first bent portion and a second bent portion that are bent and connected, the top walls 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;

[0015] 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.

[0016] To address the aforementioned technical problems, another technical solution adopted in this application is to provide a wearable device. This wearable device includes a viewing element and a wearing element as described above, wherein the wearing element is connected to the viewing element.

[0017] The beneficial effects of this application are as follows: Unlike the prior art, this application discloses a wearable device and its wearing component. By defining the thickness of the resonant cavity near the first sound outlet in the spacing direction between the speaker and the side wall of the housing as greater than the thickness of the resonant cavity away from the first sound outlet, the cavity length of the resonant cavity can be effectively shortened, thereby increasing the resonant frequency of the resonant cavity. This allows the frequency response curve produced by the speaker to be as flat as possible, avoiding discomfort to the user caused by resonance of the resonant cavity during sound output.

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.

[0032] 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.

[0038] In other words, the wearable component 30 can be directly or indirectly connected to the visible component 10 via the quick-release assembly 20.

[0039] 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 a cross-sectional view of the wearable device.

[0040] The wearable device 30 includes a housing 31 and a speaker 32. The housing 31 includes a recessed section 312, which has a downward recess 314 in the wearing state. The recessed section 312 is provided with a first sound outlet 301. The speaker 32 is disposed in the recessed section 312 and forms a resonant cavity 303 between it and the side wall of the housing 31. The first sound outlet 301 communicates with the resonant cavity 303 and is used to emit sound. In the direction of the spacing between the speaker 32 and the side wall of the housing 31, the thickness of the resonant cavity 303 at the end near the first sound outlet 301 is greater than the thickness of the resonant cavity 303 at the end away from the first sound outlet 301, thereby relatively shortening the cavity length of the resonant cavity 303 and increasing the resonant frequency of the resonant cavity 303.

[0041] Specifically, the housing 31 has a top wall 315, a bottom wall 316, a first side wall 317 and a second side wall 318, and the first side wall 317, the top wall 315, the second side wall 318 and the bottom wall 316 constitute the housing 31; wherein, in the wearing state, the first side wall 317 is close to the user's head, and the second side wall 317 faces the side away from the user's head.

[0042] In this embodiment, as Figure 6 As shown, a resonant cavity 303 is formed between the speaker 32 and the first side wall 317 of the housing 31; in other embodiments, a resonant cavity 303 is formed between the speaker 32 and the second side wall 318 of the housing 31; wherein the first sound outlet 301 is disposed on the bottom wall 316.

[0043] In this embodiment, as Figure 3 As shown, the housing 31 also includes a first connecting section 311 and a second connecting section 313. The first connecting section 311, the recessed section 312 and the second connecting section 313 are connected in sequence. The end of the first connecting section 311 away from the recessed section 312 is hinged to the quick-release assembly 20. The second connecting section 313 is used to be mounted on the user's ear.

[0044] The top wall 315, bottom wall 316, first side wall 317 and second side wall 318 also specifically constitute the first connecting section 311, the recessed section 312 and the second connecting section 313.

[0045] 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.

[0046] Further, see Figure 5Taking the scenario of a user wearing the wearable device 100 as an example, when wearing it, 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 provided in the concave section 312 is close to the ear canal opening, which is conducive to transmitting sound to the user.

[0047] In this embodiment, in conjunction with reference to Figure 3 and Figure 6 The recessed section 312 includes a first bent portion 3121 and a second bent portion 3122 that are bent and connected. 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. The first connecting section 311 is connected to the end of the first bent portion 3121 away from the second bent portion 3122, and the second connecting section 313 is connected to the end of the second bent portion 3122 away from the first bent portion 3121.

[0048] 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.

[0049] 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.

[0050] Optionally, the recessed section 312 may also be U-shaped or W-shaped, etc., and this application does not specifically limit it.

[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, the second bottom surface 3162 and the third bottom surface 3163 are located in the second bending portion 3122, and the first sound outlet 301 is disposed on the second bottom surface 3162.

[0053] By limiting the thickness of the resonant cavity 303 at the end near the first sound outlet 301 to be greater than the thickness at the end away from the first sound outlet 301 in the spaced direction between the speaker 32 and the side wall of the housing 31, the cavity length of the resonant cavity 303 can be shortened to increase the resonant frequency of the resonant cavity 303. This makes the frequency response curve generated by the speaker 32 as flat as possible and avoids discomfort caused by resonance of the resonant cavity 303 when the user wears it.

[0054] Specifically, if the recessed section 312 is only provided with the 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 wavelength of the sound wave, the resonant cavity 303 generates a resonance peak. The 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 limiting the thickness of the resonant cavity 303 near the first sound outlet 301 to be greater than the thickness of the resonant cavity 303 away from the first sound outlet 301 in the spacing direction between the speaker 32 and the first side wall 317 of the housing 31, compared with the method where the distance between the first side wall 317 and the speaker 32 is equal everywhere, the cavity length of the resonant cavity 303 can be shortened and the resonant frequency of the resonant cavity 303 can be increased.

[0055] See Figure 6 The thickness of the resonant cavity 303 at the end near the first sound outlet 301 is greater than the thickness of the resonant cavity 303 at the end away from the first sound outlet 301. For example, the resonant cavity 303 has two different thicknesses: the section near the first sound outlet 301 has a first thickness, and the section away from the first sound outlet 301 has a second thickness, with the first thickness being greater than the second thickness; or, the thickness of the resonant cavity 303 gradually decreases in the direction from the end near the first sound outlet 301 to the end away from the first sound outlet 301.

[0056] Optionally, the thickness of the resonant cavity 303 gradually decreases from the end near the first sound outlet 301 to the end away from the first sound outlet 301. The direction of the resonant cavity 303 from the end near the first sound outlet 301 to the end away from the first sound outlet 301 is defined as the length direction of the resonant cavity 303. It can be understood that the thickness of the resonant cavity 303 can decrease linearly or non-linearly along the length direction of the resonant cavity 303; for example, the thickness of the resonant cavity 303 remains constant in a certain section near the first sound outlet 301, while gradually decreasing in a certain section away from the first sound outlet 301; or, the thickness of the resonant cavity 303 gradually decreases in a certain section near the first sound outlet 301, while remaining constant in a certain section away from the first sound outlet 301.

[0057] In some embodiments, the loudspeaker 32 directly engages with the first sidewall 317 of the housing 31 to form a resonant cavity 303. The distance between the end of the first sidewall 317 of the housing 31 near the first sound outlet and the diaphragm plane of the loudspeaker 32 is greater than the distance between the end of the first sidewall 317 of the housing 31 away from the first sound outlet 301 and the diaphragm plane of the loudspeaker 32.

[0058] Since the diaphragm plane of the loudspeaker 32 is approximately flat, the first sidewall 317 is a sidewall of unequal thickness, and its inner wall surface facing the loudspeaker 32 is an inclined surface. The distance between the inner wall surface and the diaphragm plane constitutes the thickness of the resonant cavity 303.

[0059] In other embodiments, such as Figure 6 As shown, the wearable device 30 also includes a shield 33, which is disposed between the speaker 32 and the first side wall 317 of the housing 31, and cooperates with the speaker 32 to form a resonant cavity 303; wherein, the distance between the end of the shield 33 near the first sound outlet 301 and the diaphragm plane of the speaker 32 is greater than the distance between the end of the shield 33 away from the first sound outlet 301 and the diaphragm plane of the speaker 32.

[0060] Furthermore, the shield 33 includes a first shield 331 and a second shield 332 connected together. The distance between the first shield 331 and the diaphragm plane of the speaker 32 is greater than the distance between the second shield 332 and the diaphragm plane of the speaker 32. The first shield 331 is disposed adjacent to the first sound outlet 301.

[0061] The first cover 331 and the second cover 332 can both be at equal distances from the diaphragm plane of the speaker 32, or the distance between the first cover 331 and the diaphragm plane of the speaker 32 can gradually decrease along the length of the resonant cavity 303, while the distance between the second cover 332 and the diaphragm plane of the speaker 32 can remain unchanged along the length of the resonant cavity 303.

[0062] By limiting the distance between the second cover 332 and the diaphragm plane of the speaker 32 to be less than the distance between the first cover 331 and the diaphragm plane of the speaker 32, the cavity length of the resonant cavity 303 is further effectively shortened by utilizing the second cover 332, thereby increasing the resonant frequency of the resonant cavity 303.

[0063] In this embodiment, the first cover 331 has a first plane 334 facing the speaker 32, and the second cover 332 has a second plane 335 facing the speaker 32. The first plane 334 and the second plane 335 are parallel to the diaphragm plane of the speaker 32, so as to simplify the structure of the cover 33 and make it easier to manufacture.

[0064] Optionally, the side of the first cover 331 facing the speaker 32 can also be an inclined surface, the distance between the inclined surface and the diaphragm plane of the speaker 32 gradually decreases along the length of the resonant cavity 303, and the second cover 332 has a second plane 335 facing the speaker, the second plane 335 being parallel to the diaphragm plane of the speaker 32.

[0065] The shield 33 also includes a third shield 333, which is connected between the first shield 331 and the second shield 332. The third shield 333 has a transition surface 336 facing the speaker 32. The two opposite sides of the transition surface 336 are respectively connected to the first plane 334 and the second plane 335. The distance between the transition surface 336 and the diaphragm plane of the speaker 32 gradually decreases from the first plane 334 to the second plane 335, so as to smooth the side of the shield 33 facing the diaphragm plane of the speaker 32 and avoid forming a sharp corner structure that would cause the output sound energy to be lost.

[0066] Further, see Figure 5 and Figure 6 The recessed section 312 may also be provided with a second sound outlet 302, which is connected to the resonant cavity 303. The first sound outlet 301 and the second sound outlet 302 are located on adjacent sides of the resonant cavity 303. The second sound outlet 302 can be used to generate sound and increase the resonant frequency of the resonant cavity 303.

[0067] The speaker 32 can be disposed in the first bend 3121 or the second bend 3122.

[0068] In this embodiment, the loudspeaker 32 is disposed in the first bent portion 3121, 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. Thus, the second sound outlet 302 can effectively shorten the cavity length of the resonant cavity 303, thereby increasing the resonant frequency of the resonant cavity 303.

[0069] See Figure 7 , Figure 7 yes Figure 6 The diagram shows a cross-sectional view of the resonant cavity in the wearable device.

[0070] 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 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, thereby increasing the resonant frequency of the resonant cavity 303.

[0071] 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.

[0072] 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.

[0073] Optionally, the second sound outlet 302 can also be located in the middle of the second side 3032.

[0074] 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.

[0075] For example, when the second sound outlet 302 is not provided, the resonant frequency of the resonant cavity 303 is around 3.4kHz; 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 is 0.3, the resonant frequency of the resonant cavity 303 increases to 4.4kHz; 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 is 0.6, the resonant frequency of the resonant cavity 303 increases to 6.0kHz.

[0076] 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.

[0077] Unlike existing technologies, this application discloses a wearable device and its wearing component. By defining the thickness of the resonant cavity near the first sound outlet as greater than the thickness of the resonant cavity away from the first sound outlet in the spacing direction between the speaker and the side wall of the housing, the cavity length of the resonant cavity can be effectively shortened, thereby increasing the resonant frequency of the resonant cavity. This allows the frequency response curve produced by the speaker to be as flat as possible, avoiding discomfort to the user caused by resonance of the resonant cavity during sound output.

[0078] The above description is merely an embodiment of this application and does 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.
