Both the first sound-emitting unit 41 and the second sound-emitting unit 42 are relatively close to the human ear, wherein the second sound-emitting unit 42 is the closest to the human ear, ensuring that the second sound-emitting unit 42 has a lower loudness to meet the wearer's listening needs. The far-field sound pressure level is correspondingly reduced, and the dipole far-field noise reduction effect is superimposed, which can further improve the far-field privacy and enhance the user experience.

When the movable member 30 is in the storage position, as shown in FIG. 2 , the movable member 30 is retracted, and the movable member 30 is rotated to a position where it fits with the inner surface of the temple 20 , so that the first sound-emitting unit 41 and the second sound-emitting unit 41 The unit 42 is remote from the second end of the temple 20 . The width of the temple 20 can be greater than the width of the movable piece 30. When the movable piece 30 is in the storage position, the orthographic projection of the movable piece 30 on the temple 20 does not exceed the temple 20, ensuring that the movable piece 30 can be stored in the temple 20. The inner side does not affect the normal wearing of the smart glasses 100, and at the same time ensures the appearance of the smart glasses 100 to be beautiful.

In some specific embodiments of the present application, the temple 20 is provided with a sliding slot 21 , the sliding slot 21 is inclined relative to the extending direction of the temple 20 , and the movable member 30 is arranged along the sliding slot 21 . Its extension direction is movably set in the chute 21 .

That is to say, referring to FIG. 4 , the temple 20 is provided with a sliding groove 21 , and the sliding groove 21 can extend obliquely with respect to the extending direction of the temple 20 , that is, the sliding groove 21 faces the first part of the temple 20 in the width direction of the temple 20 . The two ends extend obliquely. The movable piece 30 can be arranged on the chute 21, and the movable piece 30 can slide relative to the chute 21. When the movable piece 30 is in the unfolded position, the movable piece 30 can be slid out of the chute 21, and the second movable piece 30 can be slid out of the chute 21. The end slides out to the position close to the ear hole of the human ear. Both the first sound-emitting unit 41 and the second sound-emitting unit 42 can receive the electrical signal sent by the control unit, and the first sound-emitting unit 41 and the second sound-emitting unit 42 receive the electrical signal. Then make a sound. The second sound-emitting unit 42 is closer to the ear hole of the human ear than the first sound-emitting unit 41, so that the second sound-emitting unit 42 can meet the wearer's listening needs by ensuring that the second sound-emitting unit 42 has a lower loudness. The far-field sound pressure level is correspondingly reduced, and then superimposed The far-field noise cancellation effect of the dipole can further improve the far-field privacy and improve the user experience, ensuring that the smart glasses 100 can effectively improve the far-field privacy without affecting the near-ear hearing, and effectively improve the user experience.

When the movable piece 30 is in the storage position, if the user does not need the practical audio playback function, the user can slide the movable piece 30 back into the chute 21 of the temple 20 to ensure that the movable piece 30 fits the temple 20, and use While being convenient, the overall aesthetics of the smart glasses 100 can be improved.

According to an embodiment of the present application, the movable member 30 is a telescopic member, the first end of the movable member 30 is connected to the temple 20 , the second end of the movable member 30 is retractable relative to the first end of the movable member 30 , and the second sound is emitted The unit 42 is disposed at the second end of the movable member 30 .

In other words, the movable member 30 can be a telescopic member, the first end of the movable member 30 can be connected with the temple 20, the second end of the movable member 30 can be retractable relative to the first end of the movable member 30, and the second sound generating unit 42 may be provided at the second end of the movable member 30 . When the movable member 30 is in the unfolded position, by stretching the movable member 30 to extend the second end of the movable member 30 to a position close to the ear hole of the human ear, both the first sound-emitting unit 41 and the second sound-emitting unit 42 can receive control The electrical signal sent by the unit, and the sound is produced after the first sounding unit 41 and the second sounding unit 42 receive the electrical signal. The second sounding unit 42 is closer to the ear hole of the human ear than the first sounding unit 41, so that the second sounding unit 42 can meet the wearer's listening needs by ensuring that the second sounding unit 42 has a lower loudness. The far-field sound pressure level is correspondingly reduced, and then superimposed The far-field noise cancellation effect of the dipole can further improve the far-field privacy and improve the user experience, ensuring that the smart glasses 100 can effectively improve the far-field privacy without affecting the near-ear hearing, and effectively improve the user experience.

When the movable member 30 is in the storage position, the user can drive the movable member 30 to retract to the temple 20 to ensure that the movable member 30 is in contact with the inner surface of the temple 20, so that the first sound-emitting unit 41 and the second The second sounding unit 42 is far away from the second end of the temple 20 , which is convenient to use and can also improve the overall aesthetics of the smart glasses 100 .

Of course, in this application, those skilled in the art should be able to understand that the specific shape of the movable member 30 and the specific movable form of the movable member 30 and the temple 20 can be specifically limited according to actual needs, as long as the movable member 30 can be in the unfolded position The activity forms that can be switched between the storage position and the storage position shall fall within the protection scope of this application. Meanwhile, the smart glasses 100 of the present application can be AR, VR, and various common smart glasses. Other specific structures and working principles of the smart glasses 100 of the present application can be understood and realized by those skilled in the art.
