[0043] Figure 1A is a schematic diagram of a wireless headphone assembly according to an embodiment of the present invention in a first state. Figure 1B is Figure 1A a schematic diagram of the wireless headphone assembly being converted to a second state. Please refer to Figure 1A and Figure 1B In this embodiment, the wireless headphone assembly 100 includes a charging case 200 and wireless headphones 300, wherein the wireless headphones 300 can be received in the charging case 200, and the charging case 200 is adapted to charge the wireless headphones 300. In addition, the user can take out the wireless headphones 300 from the charging case 200 according to the operation requirements and wear them on the ears.

[0044] The wireless headphones 300 include a sound output part 310 and a sound collection part 320 relative to the sound output part 310. The sound output part 310 may be provided with a speaker, and the sound collection part 320 may be provided with a microphone. Further, the charging case 200 is provided with a sound output hole 201 corresponding to the sound output part 310 and a sound collection hole 202 corresponding to the sound collection part 320. When making a voice call, the user does not need to take out the wireless headphones 300 from the charging case 200, and the wireless headphones 300 can be connected and paired with an electronic device (such as a smart phone, a tablet computer, a notebook computer or a smart watch). The voice of the calling party can be directly sent from the sound output part 310 of the wireless headphones 300 to the sound output hole 201 and transmitted to the outside through the sound output hole 201. On the contrary, the voice of the user can be transmitted from the sound collection hole 202 to the sound collection part 320 of the wireless headphones 300 and collected by the sound collection part 320.

[0045] That is to say, the wireless earphone component 100 provides different voice call modes. The user can directly make a voice call through the charging case 200, so it has excellent operation convenience. In addition to the function of voice call, the wireless earphone component 100 can also be used as a wireless speaker, and play music or other audio through the sound output part 310 of the wireless earphone 300 and the sound outlet hole 201 of the charging case 200.

[0046] Please refer to Figure 1A and Figure 1B , the charging case 200 can be automatically telescoped or manually telescoped. As the charging case 200 is telescoped, the distance between the sound outlet hole 201 and the sound receiving hole 202 can be adjusted between a first distance and a second distance greater than the first distance. In Figure 1A the first state mentioned, the sound outlet hole 201 and the sound receiving hole 202 are separated by the first distance. In Figure 1B the second state mentioned, the sound outlet hole 201 and the sound receiving hole 202 are separated by the second distance. According to the need, the extended charging case 200 is convenient for the user to hold for making a voice call. Relatively, the shortened charging case 200 is convenient for the user to store and carry around.

[0047] In an example, regardless of whether the charging case 200 is in the first state, the second state, or other states between the first state and the second state, the user can choose not to take out the wireless earphone 300 from the charging case 200, and directly receive and transmit sound through the sound outlet hole 201 and the sound receiving hole 202 of the charging case 200.

[0048] In an example, the operation mode of the wireless earphone component 100 can be switched based on the telescoping of the charging case 200. For example, the telescoping state of the charging case 200 is judged through a magnetic sensing mechanism, a light sensing mechanism, other non-contact sensing mechanisms or contact sensing mechanisms, so as to switch between a charging mode, a voice call mode, a music playing mode or other operation modes.

[0049] Please refer to Figure 1A and Figure 1B , the charging case 200 includes a first housing 210 and a second housing 220, and the second housing 220 is slidably connected to the first housing 210. On the other hand, both the first housing 210 and the second housing 220 are hollow housings. The first housing 210 is provided with a sound outlet hole 201 communicating with its internal space, and the second housing 220 is provided with a sound receiving hole 202 communicating with its internal space. Therefore, as the second housing 220 slides relative to the first housing 210, the charging case 200 is telescoped to adjust the distance between the sound outlet hole 201 and the sound receiving hole 202.

[0050] Figure 2A is Figure 1A a schematic cross-sectional view along the line L-L. Figure 2B is Figure 2ASchematic cross-sectional view of the conversion to the second state in the automatic telescopic mode. Please refer to Figure 1A and Figure 2A or Figure 1B and Figure 2B , in this embodiment, the first housing 210 is sleeved on the second housing 220, and the internal space of the first housing 210 is communicated with the internal space of the second housing 220 to facilitate the transmission of sound. Specifically, the first housing 210 has a first groove 211 communicated with the sound outlet hole 201, and the sound output part 310 is received in the first groove 211. Therefore, the sound emitted by the sound output part 310 can be sent from the first groove 211 to the sound outlet hole 201 and transmitted to the outside through the sound outlet hole 201.

[0051] The second housing 220 has a pipe 221 provided corresponding to the first groove 211, and the sound receiving hole 202 is communicated with the pipe 221. Specifically, the sound receiving part 320 is inserted into the internal space of the first housing 210 from the first groove 211. In the first state, the sound receiving part 320 is inserted into the pipe 221. In the second state, the sound receiving part 320 is moved out of the pipe 221 and is located in the internal space of the first housing 210.

[0052] As Figure 1A and Figure 2A shown, in the first state, the user's voice can enter the pipe 221 through the sound receiving hole 202 and is received by the sound receiving part 320. As Figure 1B and Figure 2B shown, in the second state, the user's voice can enter the pipe 221 through the sound receiving hole 202 and is further transmitted to the internal space of the first housing 210 to be received by the sound receiving part 320.

[0053] Please refer to Figure 2A and Figure 2B , in this embodiment, the wireless headphone assembly 100 further includes a driving module 400. Specifically, the driving module 400 is disposed in the first housing 210 and includes a motor 410, a screw 420 coupled to the motor 410, and a driving unit 430 coupled to the screw 420. When the motor 410 drives the screw 420 to rotate, the screw 420 can drive the whole of the driving unit 430 to linearly slide thereon. Since the second housing 220 abuts against the driving unit 430 or the driving unit 430 provides a supporting force for the second housing 220, the driving unit 430 that linearly slides on the screw 420 can drive the second housing 220 to slide relative to the first housing 210 to automatically adjust the telescopic length of the charging case 200 and move the sound receiving part 320 out of the pipe 221 or back into the pipe 221.

[0054] Furthermore, the driving unit 430 includes a driving platform 431 and a positioning member 432, and the positioning member 432 is movably connected to the driving platform 431. On the other hand, the driving platform 431 is sleeved on the screw 420, and the second housing 220 abuts against the positioning member 432. When the motor 410 drives the screw 420 to rotate, the screw 420 can drive the driving platform 431 to linearly slide thereon, and the positioning member 432 slides synchronously with the driving platform 431.

[0055] For example, when the driving platform 431 and the positioning member 432 slide downward synchronously along the sliding direction SD, the second housing 220 contacts the positioning member 432 and slides downward synchronously with the positioning member 432 along the sliding direction SD. Conversely, when the driving platform 431 and the positioning member 432 slide upward synchronously along the sliding direction SD, the positioning member 432 pushes the second housing 220 to slide upward synchronously along the sliding direction SD.

[0056] As Figure 2A shown in Figure 2B , the second housing 220 includes a top 222 and a bottom 223 opposite to the top 222, wherein the duct 221 extends from the top 222 to the bottom 223, and the bottom 223 is provided with a sound receiving hole 202. The top 222 has a top opening 222a, wherein the positioning member 432 passes through the top opening 222a, and at least a part of the positioning member 432 is located in the internal space of the second housing 220. On the other hand, the screw 420 extends from the internal space of the first housing 210 to the internal space of the second housing 220, wherein the screw 420 passes through the top opening 222a, and at least a part of the screw 420 is located in the internal space of the second housing 220.

[0057] Figure 3A is Figure 2A a schematic cross-sectional view of the wireless earphone assembly switching from the automatic telescopic mode to the manual telescopic mode. Figure 3B is Figure 3A a schematic cross-sectional view of switching to the second state in the manual telescopic mode. Please refer to Figure 2A , Figure 3A and Figure 3B , in this embodiment, the driving platform 431 and the positioning member 432 are arranged corresponding to the top opening 222a, and the top 222 abuts against the positioning member 432.

[0058] When the user applies an external force F to the second shell 220 to pull down the second shell 220 along the sliding direction SD, the top 222 can drive (for example, push) the positioning member 432 to move on the driving platform 431. As the second shell 220 continues to slide downward along the sliding direction SD, the positioning member 432 moves out of the second shell 220 through the top opening 222a to separate from the top 222. At this time, the coupling relationship between the second shell 220 and the driving module 400 is manually released, that is, the automatic telescopic mode is released, and it is switched from the automatic telescopic mode to the manual telescopic mode. After switching from the automatic telescopic mode to the manual telescopic mode, the user can manually pull down the second shell 220 to adjust the charging box 200 to the second state. In the second state, the sound receiving part 320 moves out of the pipe 221 and is located in the internal space of the first shell 210.

[0059] In this embodiment, the positioning member 432 is slidably connected to the driving platform 431, and is adapted to slide relative to the driving platform 431 along a sliding direction SD1 perpendicular to the sliding direction SD. Accordingly, the driving unit 430 further includes an elastic member 433, wherein the elastic member 433 may be a compression spring, and opposite ends of the elastic member 433 contact the positioning member 432 and the driving platform 431 respectively, so as to provide elastic force for resetting the positioning member 432 or ensure that the positioning member 432 maintains contact with the top 222 of the second housing 220.

[0060] When the second housing 220 is pulled downward by the external force F and slides downward along the sliding direction SD relative to the first housing 210, the top 222 drives (e.g. pushes) the positioning member 432 to slide along the sliding direction SD1 relative to the driving platform 431, and the elastic member 433 is pressed by the positioning member 432. When the positioning member 432 moves out of the second housing 220 through the top opening 222a and separates from the top 222, the elastic restoring force of the elastic member 433 drives (e.g. pushes) the positioning member 432 to slide along the sliding direction SD1 relative to the driving platform 431 and moves back to the initial position.

[0061] In other examples, the positioning member can be rotatably connected to the driving platform. Accordingly, the driving unit further includes a torsion spring, and the opposite ends of the torsion spring respectively contact the positioning member and the driving platform to provide elastic force for resetting the positioning member or ensure that the positioning member maintains contact with the top of the second shell.

[0062] Please refer to Figure 2A , Figure 2B , Figure 3A and Figure 3B, in this embodiment, the positioning member 432 has a positioning inclined surface 432a facing the first groove 211 and a reset inclined surface 432b facing the bottom 223. In the automatic telescopic mode, the top 222 of the second housing 220 remains in contact with the positioning inclined surface 432a. When the second housing 220 is pulled down by an external force F and slides downward relative to the first housing 210 along the sliding direction SD, the top 222 drives (e.g., pushes) the positioning member 432 to slide relative to the driving platform 431 along the sliding direction SD1, moving the positioning inclined surface 432a away from the top 222 and causing the positioning member 432 to move out of the second housing 220 through the top opening 222a to switch to the manual telescopic mode.

[0063] Furthermore, during the process of the positioning member 432 moving out of the second housing 220 through the top opening 222a, the top 222 slides from the positioning inclined surface 432a to the reset inclined surface 432b. Based on the elastic force exerted by the elastic member 433 on the positioning member 432, during the process of the positioning member 432 moving out of the second housing 220, the top 222 sequentially contacts the positioning inclined surface 432a and the reset inclined surface 432b and finally separates from the reset inclined surface 432b.

[0064] In one example, during the process of automatically adjusting the telescopic length of the charging case 200, the user can manually push or pull the second housing 220 according to the need to cancel the automatic telescopic mode and switch from the automatic telescopic mode to the manual telescopic mode to adjust the telescopic length of the charging case 200 more immediately or quickly.

[0065] In one example, in a state where the automatic telescopic mode is cancelled, the user can apply an external force F1 to push up the second housing 220, causing the top 222 to slide towards the positioning member 432 and come into contact with the reset inclined surface 432b. During the process of moving the positioning member 432 into the second housing 220 through the top opening 222a, the top 222 first contacts the reset inclined surface 432b and drives (e.g., pushes) the positioning member 432 to slide relative to the driving platform 431 along the sliding direction SD1, moving the reset inclined surface 432b away from the top 222. Then, the positioning member 432 gradually moves into the second housing 220, and the top 222 contacts the positioning inclined surface 432a to return to the automatic telescopic mode.

[0066] In one example, in a state where the automatic telescopic mode is released, the motor 410 can drive the driving platform 431 to slide downward through the screw 420, so that the positioning member 432 slides toward the top 222 of the second housing 220, and the reset inclined surface 432b contacts the top 222. During the process of moving the positioning member 432 into the second housing 220 through the top opening 222a, the top 222 first contacts the reset inclined surface 432b and drives (e.g., pushes) the positioning member 432 to slide relative to the driving platform 431 along the sliding direction SD1, so that the reset inclined surface 432b moves away from the top 222. Then, the positioning member 432 gradually moves into the second housing 220, and the top 222 contacts the positioning inclined surface 432a to return to the automatic telescopic mode.

[0067] In other words, the charging case 200 can be flexibly switched between the automatic telescopic mode and the manual telescopic mode. The user can manually push and pull the second housing 220 to restore or release the coupling relationship between the second housing 220 and the driving module 400, and will not cause damage to the driving module 400.

[0068] Please refer to Figure 1B With Figure 2B , in this embodiment, the first housing 210 further has a sound outlet channel 212 located between the first groove 211 and the sound outlet hole 201, and the sound outlet hole 201 communicates with the first groove 211 through the sound outlet channel 212. On the other hand, the charging case 200 further includes a cover 230 pivotally connected to the first housing 210, and the cover 230 has a second groove 231 corresponding to the first groove 211. Specifically, the inner contours of the first groove 211 and the second groove 231 are complementary to the outer contour of the sound outlet portion 310, so the sound outlet portion 310 can be received in the first groove 211 and the second groove 231.

[0069] In summary, in the wireless earphone assembly of the present invention, the charging case is provided with opposite sound output holes and sound collection holes for the user to directly make a voice call without taking out the wireless earphones from the charging case, so it has excellent operation convenience. Specifically, the sound output holes are arranged corresponding to the sound output parts of the wireless earphones, and the sound collection holes are arranged corresponding to the sound collection parts of the wireless earphones. When making a voice call, the user does not need to take out the wireless earphones from the charging case, and the wireless earphones can be connected and paired with an electronic device (such as a smart phone, a tablet computer, a notebook computer or a smart watch). The voice of the calling party can be directly sent from the sound output part of the wireless earphones to the sound output holes and transmitted to the outside through the sound output holes. On the contrary, the voice of the user can be transmitted to the sound collection part of the wireless earphones through the sound collection holes and collected by the sound collection part. On the other hand, the charging case has an automatic telescopic mode. The extended charging case is convenient for the user to hold for a voice call, and the shortened charging case is convenient for the user to store and carry around. In addition, the user can manually release the automatic telescopic mode and switch to the manual telescopic mode to manually adjust the telescopic length of the charging case.

[0070] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. Any person skilled in the art within the technical field to which the present invention pertains can make some modifications and refinements without departing from the spirit and scope of the present invention.
