[0089] Please refer to Figures 1 to 3 , Figure 1 FIG1 is a perspective view of the augmented reality glasses 10 and the detachable earphone module according to an embodiment of the present disclosure. Figure 2 is a perspective view of a detachable earphone module 100 according to an embodiment of the present disclosure, and Figure 3An exploded view of the detachable earphone module 100 according to an embodiment of the present disclosure. In this embodiment, the augmented reality glasses 10 can include a frame 11, two temples 12, 13, two speakers 15, and two detachable earphone modules 100, 100A.

[0090] As shown in FIG. 1, the two temples 12, 13 are connected to the two sides of the frame 11, and the two speakers 15 can be respectively disposed in the two temples 12, 13. Each of the temples 12, 13 (e.g., the bottom) is provided with a first sound outlet opening 12H, which is communicated with the speaker 15, so that the sound emitted by the speaker 15 can be transmitted to the outside of the temple 12, 13 through the first sound outlet opening 12H. Figure 1

[0091] Further, the detachable earphone modules 100, 100A are detachably mounted on the temples 12, 13, respectively, and when the user wears the augmented reality glasses 10, the detachable earphone modules 100, 100A are configured to guide the sound emitted by the speakers 15 to the user's ears.

[0092] The number and the disposed position of the speakers 15 are not limited to this embodiment. For example, the augmented reality glasses 10 can only include one speaker 15, which is disposed in the frame 11 and is communicated with the first sound outlet opening 12H and the detachable earphone module 100, 100A through a sound guide channel (not shown in the figure) in the frame 11 and the temple 12.

[0093] In addition, the augmented reality glasses 10 can further include two first blocking pieces 21 and two second blocking pieces 22, which are detachably mounted on the temples 12, 13, and the detachable earphone module 100 or 100A is located between the first blocking piece 21 and the second blocking piece 22.

[0094] The first blocking piece 21 and the second blocking piece 22 can limit the position of the detachable earphone module 100, 100A on the temple 12, 13 to avoid the detachable earphone module 100, 100A from sliding and affecting the user's experience. The first blocking piece 21 and the second blocking piece 22 can be made of a resilient material, for example, made of a rubber material, and can have a U-shaped structure to be smoothly clamped on the temple 12, 13.

[0095] Since the two detachable earphone modules 100, 100A are symmetrically configured, the following paragraphs will only describe the specific structure of the detachable earphone module 100. In this embodiment, as shown in FIG. 2, the detachable earphone module 100 can include a clamping member 102 and a sound outlet assembly 106. Figure 2

[0096] ​​The engaging member 102 is configured to engage with the frame 12, and the engaging member 102 has a sound receiving passage 102T which is located at the first sound outlet opening 12H of the frame 12. The sound outlet assembly 106 is configured to be connected to the engaging member 102, and the engaging member 102 and the sound outlet assembly 106 can be integrally formed, but are not limited thereto. In other embodiments, the engaging member 102 and the sound outlet assembly 106 can be separable and combinable components.

[0097] As shown in FIG. 1, the sound outlet assembly 106 can have an upper cover 108, a bottom cover 112, and an outer cover 114. The upper cover 108 is fixedly coupled to the bottom cover 112 along a main axis MX to form a communication passage 116. The outer cover 114 is fixedly coupled to the bottom cover 112 along the main axis MX to form a front chamber 118 with the bottom cover 112 and the upper cover 108. The communication passage 116 is in communication with the sound receiving passage 102T, and the communication passage 116 is in communication with the front chamber 118. Figure 3 Further, the outer cover 114 has a second sound outlet opening 119 formed thereon and configured to be in communication with the front chamber 118. The second sound outlet opening 119 can be composed of a plurality of sub-openings 1191, and the sub-openings 1191 are formed on the outer cover 114 in a radial manner. It is worth noting that the area of the second sound outlet opening 119 is 20% to 80% of the area of the outer cover 114 when viewed along the main axis MX.

[0098] For example, when the area of the second sound outlet opening 119 is 20% of the area of the outer cover 114, the detachable earphone module 100 can achieve the best bass output effect. As shown in FIG. 2, the outer cover 114 can be provided with one or more flaps 1141 connected to a lever 1143, and the lever 1143 can be moved along a groove 1145 to drive the flaps 1141 to rotate to shield a portion of the sub-openings 1191, thereby adjusting the area ratio of the second sound outlet opening 119 to the outer cover 114 to achieve different sound output effects.

[0099] Figure 3 Further, as shown in FIG. 3, the front chamber 118 has a first inner diameter DD1, and the second sound outlet opening 119 has a second inner diameter DD2. The first inner diameter DD1 can be greater than the second inner diameter DD2, and such a configuration can increase the sound output effect of the detachable earphone module 100 at high frequencies.

[0100] Further, as shown in FIG. 4, the outer cover 114 has a third inner diameter DD3, and the second sound outlet opening 119 has a fourth inner diameter DD4. The third inner diameter DD3 can be less than the fourth inner diameter DD4, and such a configuration can increase the sound output effect of the detachable earphone module 100 at low frequencies. Figure 3 In addition, it is worth noting that, as shown in FIG. 5, the outer cover 114 can be provided with one or more flaps 1141 connected to a lever 1143, and the lever 1143 can be moved along a groove 1145 to drive the flaps 1141 to rotate to shield a portion of the sub-openings 1191, thereby adjusting the area ratio of the second sound outlet opening 119 to the outer cover 114 to achieve different sound output effects.

[0101] Figure 1 ​​As shown, the sound emitting assembly 106 is extended along a first direction D1 by the engaging member 102, while the frame 12 is extended along a second direction D2, and the included angle between the first direction D1 and the second direction D2 is between 0 and 90 degrees. Based on such design, the augmented reality glasses 10 and the detachable earphone module 100 can be more ergonomic to increase the comfort when worn by the user.

[0102] In this embodiment, as shown, the detachable earphone module 100 can further include a tuning element 141 disposed on the engaging member 102 and shielding a first opening 102T1 of the sound receiving passage 102T. The tuning element 141 is, for example, a foam or a porous sponge, but is not limited thereto. Based on such configuration, the bass output effect of the detachable earphone module 100 can be increased. Figure 2

[0103] In addition, it is worth noting that the size of the first opening 102T1 is greater than the size of the first sound emitting opening 12H. For example, the size of the first opening 102T1 can be more than twice the size of the first sound emitting opening 12H. Based on such configuration, it can be ensured that the first sound emitting opening 12H is completely within the range of the first opening 102T1, and there is no problem of sound leakage.

[0104] Next, please refer to Figure 2 and Figure 4 . Figure 4 is a perspective view of the detachable earphone module 100 according to an embodiment of the present disclosure from another angle. In this embodiment, the detachable earphone module 100 can further include a first sound insulation element 142 disposed on the engaging member 102 and surrounding the tuning element 141 and the first opening 102T1. Further, the engaging member 102 can have a first hook portion 1021 and a second hook portion 1022, and the first sound insulation element 142 is disposed on an inner wall surface 1024 of the first hook portion 1021 and the second hook portion 1022.

[0105] The first sound insulation element 142 and the tuning element 141 can be made of different materials. For example, the tuning element 141 can be made of, for example, polyurethane (PU) foam, polyethylene (PE) foam, glass fiber cotton, rock wool, polyester fiber, wood wool, mineral wool, etc., and the first sound insulation element 142 can be made of, for example, rubber, resin, calcium silicate board, gypsum board, polyvinyl chloride (PVC) polymer rubber, etc., but is not limited thereto. Further, the density of the first sound insulation element 142 can be greater than the density of the tuning element 141, but is not limited thereto.

[0106] ​In addition, the first sound insulation member 142 can be made of a flexible material, such that when the engaging member 102 is engaged with the frame 12, the first sound insulation member 142 is located between the engaging member 102 and the frame 12 and completely seals the periphery of the first opening 102T1.

[0107] With the configuration of the first sound insulation member 142, it can be ensured that the sound emitted from the first sound outlet opening 12H can completely enter the first opening 102T1 without leaking out from between the engaging member 102 and the frame 12. That is, the first sound insulation member 142 can completely fill the gap between the engaging member 102 and the frame 12.

[0108] In addition, in other embodiments, the configuration of the first sound insulation member 142 can be omitted, and the engaging member 102 can be made of a flexible material, such as a flexible rubber material. Due to the inwardly flexible force, the first and second hook portions 1021 and 1022 can securely hold the frame 12 on opposite sides of the frame 12, and when the engaging member 102 is engaged with the frame 12, the inner wall surface 1024 of the first and second hook portions 1021 and 1022 can completely adhere to the frame 12 to seal the first opening 102T1 of the sound receiving passage 102T.

[0109] Based on such a configuration, similarly, the sound emitted from the first sound outlet opening 12H can completely enter the first opening 102T1 without leaking out from between the engaging member 102 and the frame 12.

[0110] Next, please refer to Figure 5 , Figure 5 is an exploded view of a detachable earphone module 100B according to another embodiment of the present disclosure. The detachable earphone module 100B is similar in structure to the detachable earphone module 100 of the foregoing embodiments, and the upper cover 108 of this embodiment is also fixedly covered on the bottom cover 112 to form the communication passage 116. It is worth noting that the bottom cover 112 of this embodiment can be further formed with a plurality of staggered partitions 1121 arranged in the communication passage 116 to form a looped pipe 1161.

[0111] Based on such a structural configuration, the path length of the sound traveling in the communication passage 116 can be increased, thereby increasing the overall bass output effect. As shown in Figure 5 , in this embodiment, the bottom cover 112 is formed with three partitions 1121, but the number thereof is not limited thereto. That is, as long as the configuration can form a winding looped pipe 1161, it is within the scope of the present disclosure.

[0112] Next, please refer to Figures 6 to 8 . Figure 6 is a perspective view of a detachable earphone module 100C according to another embodiment of the present disclosure,Figure 7 is a perspective view of the detachable earphone module 100C according to another embodiment of the present disclosure, and Figure 8 is an exploded view of the detachable earphone module 100C according to another embodiment of the present disclosure. Similarly, the engaging member 102 is made of a resilient material and has a first hook portion 1021 and a second hook portion 1022.

[0113] It is worth noting that the first hook portion 1021 and the second hook portion 1022 of this embodiment are separable components, and the first hook portion 1021 is rotatably connected to the second hook portion 1022. For example, as shown in Figure 7 , the engaging member 102 can further include a rotating shaft member 102X fixed to two fixing structures 1022F of the second hook portion 1022 and passing through a receiving structure 1021C of the first hook portion 1021.

[0114] Furthermore, the second hook portion 1022 can further have two resiliently flexible structures 1022E configured to block a portion of the first hook portion 1021. When a user applies a force along a second axial direction AX2 (a force outward), the first hook portion 1021 can push the resiliently flexible structures 1022E to be stretched, and then the first hook portion 1021 can rotate around the rotating shaft member 102X, for example, to a release position (indicated by a dashed line). Figure 6

[0115] Conversely, when the detachable earphone module 100C is to be installed on the frame 12, the user can first engage the second hook portion 1022 with the frame 12, and then apply a force along the second axial direction AX2 (a force inward), so that the first hook portion 1021 can rotate around the rotating shaft member 102X and push the resiliently flexible structures 1022E to be squeezed between the two resiliently flexible structures 1022E.

[0116] Thus, as shown in Figure 7 , the first hook portion 1021 and the second hook portion 1022 can be located on opposite sides of the frame 12 to hold the frame 12. At this time, the first hook portion 1021 is located at an engaging position relative to the second hook portion 1022.

[0117] Based on the above configuration, the user can more easily install or detach the detachable earphone module 100C from the frame 12, and can also easily adjust the position of the detachable earphone module 100C.

[0118] Then, as shown in Figure 8 ​As shown, in this embodiment, the engaging member 102 can further have a movable section 1023, which is protruded from the second hook section 1022 along a first axial direction AX1 toward the bottom cover 112 of the sound emitting assembly 106. Specifically, the bottom cover 112 can further have a receiving section 1123, which is communicated with the communication passage 116, and the receiving section 1123 is configured to receive the movable section 1023, so that the movable section 1023 can move along the first axial direction AX1 within the receiving section 1123.

[0119] As shown in FIG. 1 1, the receiving section 1123 can have a blocking structure 112B, which is configured to block a protruding structure 1025 of the movable section 1023. Based on such configuration, the movable section 1023 can be prevented from moving upwardly out of the receiving section 1123. Figures 6 to 9 .
