[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, the descriptions of "first", "second", etc. in the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0042] In response to the technical problems mentioned in the background technology, the present invention proposes a wristband electronic device, which aims to avoid the sound of the speaker being blocked by the wrist skin when worn, so as to improve the sound effect.

[0043] The specific structure of the wristband electronic device proposed by the present invention will be described in detail below in a specific embodiment:

[0044] like Figures 1 to 4 As shown, in one embodiment of a wristband electronic device 100 of the present invention, the wristband electronic device 100 includes a device body 10 and a wristband 30. A speaker 11 is disposed within the device body 10. The wristband 30 is connected to the device body 10 and is intended to be worn on the wrist. A sound output structure 311 is disposed on the surface of the wristband 30 facing away from the wrist. The speaker 11 is connected to the sound output structure 311 via an internal channel 100a. The sound output structure 311 is configured to diffuse sound to the outside world.

[0045] In this embodiment, the wristband electronic device 100 can be a smartwatch, a smart bracelet, or other wristband electronic devices 100. The speaker 11 on the device body 10 and the sound output structure 311 on the wristband 30 can be connected via a sound-conducting structure, such as a hose. Alternatively, the device body 10 and the wristband 30 can be integrally formed, with a channel 100a formed inside the structure to connect the speaker 11 to the sound output structure 311. Alternatively, the speaker 11 on the device body 10 and the sound output structure 311 on the wristband 30 can be connected in other ways.

[0046] The sound-emitting structure 311 can be an arc-shaped groove 31d, which is connected to the speaker 11 through the channel 100a. The sound of the speaker 11 is transmitted from the arc-shaped groove 31d through the channel 100a, which helps to emit sound externally; the sound-emitting structure 311 can also be a plane with multiple sound holes, all of which are connected to the speaker 11 through the channel 100a, and the sound of the speaker 11 is transmitted from the multiple sound holes through the channel 100a; the sound-emitting structure 311 can also be other forms of structures that diffuse sound to the outside world.

[0047] The sound waves emitted by the speaker 11 pass through the air in the channel 100 a and the air in the sound producing groove 31 b and propagate to the sound producing structure 311 .

[0048] It can be understood that a speaker 11 is provided inside the device body 10, the wristband 30 is connected to the device body 10, and a sound output structure 311 is provided on the surface of the wristband 30 facing away from the wrist. The speaker 11 is connected to the sound output structure 311 through the internal channel 100a. The sound output structure 311 is used to diffuse sound to the outside world, so that the sound played by the speaker 11 can be transmitted from the sound output structure on the wristband 30. Since the sound output structure is located on the surface of the wristband 30 facing away from the wrist, after wearing the smart wearable device, the skin of the wrist can be prevented from blocking the sound output structure, and the sound output of the speaker 11 can be prevented from being blocked by the skin of the wrist due to wearing, thereby improving the sound output effect. In this way, when worn, the sound output structure will not be blocked by the flesh of the arm, and the beautiful design of the product will not be affected, thereby improving the user experience.

[0049] like Figures 2 to 4 As shown, in one embodiment of the wristband electronic device 100 of the present invention, the channel 100a includes a sound-producing segment 101a, a sound-guiding segment 103a, and a sound-transmitting segment 105a. The sound-producing segment 101a is disposed within the wristband 30, with one end of the sound-producing segment 101a connected to the sound-emitting structure. One end of the sound-guiding segment 103a is connected to the end of the sound-producing segment 101a facing away from the sound-emitting structure. The sound-transmitting segment 105a is disposed within the device body 10, with one end of the sound-transmitting segment 105a connected to the speaker 11, and the end of the sound-transmitting segment 105a facing away from the speaker 11 is connected to the end of the sound-guiding segment 103a facing away from the sound-producing segment 101a.

[0050] In this embodiment, the sound guide section 103a can use a hose to connect the device body 10 and the wristband 30 to connect the speaker 11 with the sound output structure 311; the sound guide component 33 can also be connected to the wristband 30 by rotatably connecting the sound guide component 33 to the wristband 30, and the sound guide component 33 can be connected to the device body 10 by fixedly connecting the sound guide component 33 to the device body 10, thereby connecting the speaker 11 with the sound output structure 311; other effective methods can also be used.

[0051] It can be understood that the device body 10 and the wristband 30 are connected through the sound guide segment 103a, so that the device body 10 and the wristband 30 do not have to maintain a state of being unable to move relative to each other in order to maintain the continuity of the channel 100a connecting the speaker 11 and the sound output structure 311. That is, since the sound guide segment 103a can maintain the connection between the device body 10 and the wristband 30, it can allow the device body 10 and the wristband 30 to move relative to each other, and can serve as the basis for achieving a rotational connection between the device body 10 and the wristband 30.

[0052] like Figures 2 to 5As shown, in one embodiment of the wristband electronic device 100 of the present invention, the wristband 30 includes a band body 31 and a sound guide component 33. One end of the band body 31 is rotatably connected to the device body 10 and is provided with a receiving groove 31a. The band body 31 is provided with a sound output structure 311. The band body 31 is used to be worn on the wrist. The outer surface of the device body 10 facing the receiving groove 31a is formed with a first connecting port 10a connected to the sound transmission section 105a. The groove wall of the receiving groove 31a is formed with a second connecting port 310a connected to the sound sounding section 101a. The sound guide component 33 is at least partially accommodated in the receiving groove 31a. One end of the sound guide component 33 is connected to the sound transmission section 105a through the first connecting port 10a, and the other end is connected to the sound sounding section 101a through the second connecting port 310a.

[0053] In this embodiment, two lugs are protruding from one end of the belt body 31 facing the device body 10, and the two lugs are spaced apart in the width direction of the belt body 31, thereby forming a receiving groove 31a. There are two ways to set the sound guide component 33. Method 1: a part of the sound guide component 33 is located between the two lugs, and the other part of the sound guide component 33 is exposed in the receiving groove 31a and connected to the first connecting port 10a of the device body 10; Method 2: the entire sound guide component 33 is located between the two lugs, and the device body 10 is provided with a connecting piece protruding from the outer surface of the belt body 31, and the connecting piece has a first connecting port 10a. The connecting piece is connected to the sound guide component 33 to achieve communication. The sound guide component 33 is sandwiched between the two lugs, which can prevent the sound guide component 33 from moving in the width direction of the belt body 31.

[0054] It can be understood that a accommodating groove 31a is provided at one end of the belt body 31 connected to the device body 10, and the sound guide component 33 is accommodated in the accommodating groove 31a, so that the sound guide component 33 can move in the accommodating groove 31a, and the belt body 31 is connected to the device body 10 through the sound guide component 33, so that when the belt body 31 and the sound guide component 33 move relative to each other, the channel 100a is maintained in a connected state to ensure that the speaker 11 is connected to the sound output structure 311.

[0055] like Figures 2 to 4As shown, in an embodiment of the wristband electronic device 100 of the present invention, the sound guide component 33 includes a sound guide adapter 331 and a sound guide tube 333. The sound guide adapter 331 has two ends arranged back to back. One end of the sound guide adapter 331 is inserted into the accommodating groove 31a, and the other end of the sound guide adapter 331 extends toward the first connecting port 10a and is inserted into the first connecting port 10a. A first sound channel 331a connected to the sound transmission section 105a is formed inside the sound guide adapter 331. The sound guide tube 333 is accommodated in the accommodating groove 31a and extends along the rotation axis of the belt body 31 and the device body 10. One end of the sound guide tube 333 is rotatably inserted into the side wall of one end of the sound guide adapter 331, and the other end of the sound guide tube 333 extends toward the second connecting port 310a and is inserted into the second connecting port 310a. A second sound channel 333a is formed in the sound guide tube 333, and the second sound channel 333a is connected to the first sound channel 331a to form a sound guide section 103a.

[0056] In this embodiment, it is understood that one end of the sound guide tube 333 is rotatably inserted into the side wall of one end of the sound guide adapter 331, and the axis of the sound guide tube 333 and the rotation axis of the belt body 31 and the device body 10 are coaxially arranged. Therefore, during the process of rotational connection between the belt body 31 and the device body 10, the connection state of the channel 100a can be maintained by the rotation between the sound guide tube 333 and the sound guide adapter 331 to ensure that the speaker 11 is connected to the sound output structure 311.

[0057] like Figures 3 to 5 As shown, in one embodiment of the wristband electronic device 100 of the present invention, a sound guide adapter 331 is inserted into the first communication port 10a at one end, protruding into the inner cavity of the device body 10. A sound guide sleeve 13 is provided within the inner cavity of the device body 10. One end of the sound guide sleeve 13 is sleeved over the end of the sound guide adapter 331 that protrudes into the inner cavity of the device body 10, and the other end of the sound guide sleeve 13 is capped over the speaker 11.

[0058] In this embodiment, one end of the sound guide adapter 331 enters the inner cavity of the device body 10 from the first connecting port 10a. The sound guide sleeve 13 is located in the inner cavity of the device body 10, and the two ends of the sound guide sleeve 13 are interconnected. Among them, one end of the sound guide sleeve 13 is sleeved on one end of the sound guide adapter 331 extending into the inner cavity of the device body 10, and the other end is embedded in the speaker 11. In this way, the speaker 11 can be connected to the sound guide adapter 331, and connected to the sound output structure 311 via the sound guide adapter 331. With such a setting, on the one hand, the sound guide sleeve 13 can prevent sound leakage, and on the other hand, the sound guide sleeve 13 can facilitate the connection of the sound guide adapter 331 to the setting body, and also facilitate the installation of the speaker 11 in the inner cavity of the device body 10, thereby improving assembly efficiency.

[0059] It should be noted that the sound guide sleeve 13 can be a silicone sleeve, a sleeve made of plastic material, or other forms of the sound guide sleeve 13.

[0060] like Figure 3 and Figure 4 As shown, in one embodiment of the wristband electronic device 100 of the present invention, two first sealing rings 3311 are mounted on the end of the sound guide adapter 331 facing away from the accommodating groove 31a. One first sealing ring 3311 is located within the sound guide sleeve 13 and is squeezed by the inner wall of the sound guide sleeve 13. The other first sealing ring 3311 is located within the first communication port 10a and is squeezed by the inner wall of the first communication port 10a.

[0061] It can be understood that a first sealing ring 3311 is located in the sound guide sleeve 13 and is squeezed by the inner wall surface of the sound guide sleeve 13, thereby achieving a sealed connection between the sound guide sleeve 13 and the sound guide adapter 331; another first sealing ring 3311 is located in the first communication port 10a and is squeezed by the inner wall surface of the first communication port 10a, thereby achieving a sealed connection between the inner wall surface of the first communication port 10a and the sound guide adapter 331. In this way, not only can the sound leakage during the propagation of the sound emitted by the speaker 11 in the channel 100a be reduced, but also dust can be prevented from entering the inner cavity of the device body 10. In addition, the use of two first sealing rings 3311 for sealing to prevent sound leakage not only has a good sealing effect, but also, when one of the first sealing rings 3311 fails, there is still another first sealing ring 3311 for sealing, which can effectively ensure the reliability of the seal.

[0062] like Figure 2 、 Figure 5 as well as Figure 6 As shown, in an embodiment of the wristband electronic device 100 of the present invention, the sound guide tube 333 is inserted into one end of the sound guide adapter 331 and is sleeved with a second sealing ring 3331, and the outer surface of the second sealing ring 3331 is squeezed by the inner wall of the first sound channel 331a.

[0063] It can be understood that a second sealing ring 3331 is provided on one end of the sound guide tube 333 inserted into the sound guide adapter 331, and the outer surface of the second sealing ring 3331 is squeezed by the inner wall of the first sound channel 331a, thereby realizing a sealed connection between the sound guide tube 333 and the sound guide adapter 331. In this way, sound leakage during the propagation of the sound emitted by the speaker 11 in the channel 100a can be reduced.

[0064] like Figure 2 and Figure 6As shown, in one embodiment of the wristband electronic device 100 of the present invention, the second connecting port 310a extends along the rotation axis of the belt body 31 and the device body 10 on the side wall of the accommodating groove 31a to form a receiving hole 3101a, and the hole wall of the receiving hole 3101a is provided with a sound guide hole 310c connected to the sound transmission section. One end of the sound guide tube 333 facing away from the sound guide adapter 331 is inserted into the receiving hole 3101a, and the other end of the sound guide tube 333 facing away from the sound guide adapter 331 is sealed. The wall of the sound guide tube 333 is provided with a sound hole 333b connected to the second sound channel 333a. The sound hole 333b and the sound guide hole 310c are located in the same area and are connected to each other. Two third sealing rings 3333 are provided on the outer side of the sound guide tube 333. The sound hole 333b and the sound guide hole 310c are both located between the two third sealing rings 3333. The wall of the receiving hole 3101a squeezes the two third sealing rings 3333 respectively.

[0065] In this embodiment, the sound hole 333b and the sound guide hole 310c are located in the same area, meaning that the sound hole 333b is located at a certain section of the sound guide tube 333, and the sound guide hole 310c is located at the same section of the receiving hole 3101a. The sound hole 333b and the sound guide hole 310c can be positioned opposite each other or offset. The sound guide tube 333 has a section that includes the sound hole 333b, and third sealing rings 3333 are respectively mounted on both ends of the section. The two third sealing rings 3333 support the sound guide tube 333 within the receiving hole 3101a, thereby creating a gap between the section of the sound guide tube 333 that includes the sound hole 333b and the wall of the receiving hole 3101a. The sound hole 333b and the sound guide hole 310c can communicate through this gap. Of course, in order to expand the gap to facilitate sound propagation, the two ends of the tube section of the sound guide tube 333 with the sound hole 333b can be respectively provided with abutments along the circumferential direction, and each abutment is covered with a third sealing ring 3333, which relies on the two third sealing rings 3333 to seal and prevent sound leakage.

[0066] Specifically, the rotation axis between the band body 31 and the device body 10 is defined as the rotation axis. The second communication port 310a extends along the groove wall of the accommodating groove 31a to form a receiving hole 3101a, and the receiving hole 3101a is coaxially arranged with the rotation axis. One end of the sound guide tube 333 is inserted into the receiving hole 3101a, so that the sound guide tube 333 is coaxially arranged with the rotation axis. The other end of the sound guide tube 333 is rotatably inserted into the side wall of one end of the sound guide adapter 331. With this arrangement, when the user wears the wristband electronic device 100, the band body 31 rotates about the rotation axis, while the device body 10 and the sound guide adapter 331 remain stationary. The sound guide tube 333 and the sound guide adapter 331 can rotate relative to each other. Therefore, during the process of the band body 31 and the device body 10 being rotated and connected, the band body 31 can be maintained in communication with the device body 10 via the sound guide tube 333 and the sound guide adapter 331, thereby maintaining communication between the speaker 11 and the sound output structure 311.

[0067] As can be understood, the sound hole 333b and the sound guide hole 310c are located in the same area and are interconnected. Two third sealing rings 3333 are provided on the outer side of the sound guide tube 333. The sound hole 333b and the sound guide hole 310c are both located between the two third sealing rings 3333. The wall of the receiving hole 3101a squeezes the two third sealing rings 3333, thereby achieving a sealed connection between the inner wall of the receiving hole 3101a and the ends of the tube section of the sound guide tube 333 provided with the sound hole 333b, while ensuring that the sound hole 333b and the sound guide hole 310c are connected. This not only reduces sound leakage during the propagation of sound from the speaker 11 within the channel 100a, but also prevents dust. The sealing ring is generally an O-ring, which has good elasticity and is easy to install.

[0068] like Figure 1 、 Figure 3 as well as Figure 4 As shown, in an embodiment of the wristband electronic device 100 of the present invention, a sound pronunciation groove 31b is provided on the surface of the wristband 30 facing away from the wrist, and the end of the sound pronunciation segment 101a facing away from the sound guide segment 103a passes through to the bottom wall of the sound pronunciation groove 31b, and the sound pronunciation groove 31b forms a sound output structure 311. The sound pronunciation groove 31b is gradually expanded from the bottom of the groove to the groove mouth in a cross section perpendicular to the depth direction, and the sound pronunciation groove 31b is used to diffuse sound.

[0069] It can be understood that by setting the pronunciation groove 31b, the sound can be diffused and transmitted to the pronunciation segment 101a, so that the pronunciation groove 31b helps to emit the sound, and the sound emitted by the speaker 11 is transmitted along the sound guide tube 333 to the sound transmission cavity 31c, and then transmitted from the sound transmission cavity 31c to the external environment through the sound hole 311b opened at the bottom of the pronunciation groove 31b.

[0070] Specifically, in order to enhance the sound diffusion function, the sound-producing groove 31b is gradually expanded from the groove bottom to the groove mouth in the cross section perpendicular to the depth direction, forming a trumpet-like structure, which can promote the diffusion of sound and amplify the sound.

[0071] It should be noted that the sound-producing groove 31b can be an arc-shaped groove, a trapezoidal groove, or a groove of other shapes.

[0072] like Figure 3 and Figure 4 As shown, in an embodiment of the wristband electronic device 100 of the present invention, a protrusion 310b is provided on the bottom of the sound groove 31b.

[0073] It can be understood that the protrusion 310b is provided on the bottom of the sound groove 31b, which can prevent the sound guide section 103a from passing through to one end of the bottom wall of the sound groove 31b due to clothing or skin being too tight when collecting sound, that is, preventing clothing or other objects from blocking the sound hole 311b and affecting the sound quality.

[0074] It should be noted that the number of the protrusions 310b can be 1, 2, 3, 4, 5, 6, etc. There is no limitation on the number of the protrusions 310b, and those skilled in the art can set them according to actual needs.

[0075] like Figure 3 and Figure 4 As shown, in an embodiment of the wristband electronic device 100 of the present invention, the wristband 30 is provided with a sound transmission cavity 31c, and a sound hole 311b is provided at the bottom of the sound groove 31b. The end of the sound hole 311b away from the sound groove 31b is connected to the sound transmission cavity 31c, and the cavity wall of the sound transmission cavity 31c is provided with a sound guide hole 310c connected to the sound transmission segment 105a. The sound hole 311b, the sound transmission cavity 31c, and the sound guide hole 310c are connected in sequence to form the sound transmission segment 101a.

[0076] It can be understood that the provision of the sound transmission cavity 31c can diffuse the sound transmitted by the sound hole 311b, thereby promoting the propagation of the sound to the outside world. When multiple sound holes 311b are provided, the sound transmission cavity 31c can simultaneously diffuse the sound transmitted by all the sound holes 311b, thereby promoting the propagation of the sound to the outside world.

[0077] It should be noted that the number of the sound holes 311b can be 1, 2, 3, 4, 5, 6, etc. There is no limitation on the number of the sound holes 311b, and those skilled in the art can set them according to actual needs.

[0078] like Figure 3 and Figure 4 As shown, in an embodiment of the wristband electronic device 100 of the present invention, a groove 31d is provided on the surface of the wristband 30 facing the wrist, and the sound hole 311b is connected to the bottom wall of the groove 31d at one end away from the sound groove 31b. A sound guide hole 310c is provided on the side wall of the groove 31d, and a cover plate 313 is provided at the opening of the groove 31d. The cover plate 313 is used to seal the groove 31d and enclose the groove wall of the groove 31d to form a sound transmission cavity 31c.

[0079] It can be understood that a cover plate 313 is provided at the opening of the groove 31d, and the cover plate 313 can seal the groove 31d. The cover plate 313 and the groove wall of the groove 31d enclose the sound transmission cavity 31c, thereby facilitating the molding of the sound transmission cavity 31c. Specifically, due to the small thickness of the wristband 30, it would be difficult to form the sound transmission cavity 31c in the wristband 30 through an injection molding process. The wristband electronic device 100 of the present invention adopts a groove 31d opened on the surface of the wristband 30, and cooperates with the cover plate 313 for sealing, so that the cover plate 313 and the groove wall of the groove 31d enclose the sound transmission cavity 31c. This method can facilitate processing and manufacturing and reduce the difficulty of the process. In addition, the design of the cover plate 313 can easily clean the dust in the sound transmission cavity 31c to ensure smooth sound transmission.

[0080] It should be noted that the cover plate 313 seals the groove 31d by sticking and fixing the cover plate 313 on the notch of the groove 31d with waterproof double-sided tape; or by sticking and fixing the cover plate 313 on the notch of the groove 31d with laser adhesive film; or other effective sealing methods can be used.

[0081] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
