It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. In addition, “and / or” in the specification and claims indicates at least one of the connected objects, and the character “ / ” generally indicates that the front and rear associated objects are in an “or” relationship.

[0048] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application. Figures 1 to 11 The earphone provided by the embodiments of the present application is described in detail below in conjunction with specific embodiments and application scenarios.

[0049] As Figures 1 to 10As shown, the earphone of the embodiment of the present application comprises a shell 10, a sound generating structure 20 and a movable member 30. The shell 10 has a cavity, and the sound generating structure 20 is arranged in the cavity. The sound generating structure 20 divides the cavity into a first sound cavity 11 and a second sound cavity 12. The first sound cavity 11 can serve as a front sound cavity of the sound generating structure 20, and the second sound cavity 12 can serve as a rear sound cavity of the sound generating structure 20. At least one of the shell 10 and the sound generating structure 20 is provided with a passage 21, and the passage 21 communicates the first sound cavity 11 and the second sound cavity 12. The shell 10 is provided with a first sound outlet hole 13 and a second sound outlet hole 14. The first sound outlet hole 13 and the second sound outlet hole 14 can be located on opposite sides of the shell 10, so that when the earphone is worn on a human ear, the first sound outlet hole 13 can face the human ear, and the second sound outlet hole 14 can face the external environment. The first sound outlet hole 13 communicates with the first sound cavity 11, and the second sound outlet hole 14 communicates with the second sound cavity 12. The sound in the first sound cavity 11 can be transmitted out through the first sound outlet hole 13, and the sound in the external environment can enter the second sound cavity 12 through the second sound outlet hole 14. The movable member 30 can move. When the movable member 30 is in a first position, the movable member 30 blocks the passage 21. When the movable member 30 is in a second position, the movable member 30 avoids the passage 21. The movable member 30 can be driven to rotate or move, and the rotation or movement of the movable member 30 can change the position of the movable member 30, so that the movable member 30 can block or avoid the passage 21. The movable member 30 can be driven to move by a driving mechanism. The driving mechanism can be a driving motor. For example, the driving mechanism can drive the movable member 30 to rotate or move.

[0050] The movable member 30 can be driven to move to block or avoid the passage 21 according to actual needs. The earphone can be a wireless earphone. When the movable member 30 blocks the passage 21, the first sound cavity 11 and the second sound cavity 12 are not in communication, and the sound generated by the sound generating structure 20 can be heard through the earphone. At this time, the first sound cavity 11 is isolated from the external environment, and external noise is not easy to enter the user's ear, so that better noise reduction effect and better sound quality effect can be obtained, which is beneficial to the user to obtain an immersive experience. When the movable member 30 avoids the passage 21, the first sound cavity 11 and the second sound cavity 12 are in communication. The sound in the external environment can enter the second sound cavity 12 through the second sound outlet hole 14, and the sound in the second sound cavity 12 can enter the first sound cavity 11 through the passage 21, and then be transmitted out from the first sound outlet hole 13. The first sound cavity 11 and the second sound cavity 12 are in communication. At this time, when the earphone is used, not only the audio played by the earphone can be heard, but also the user can hear the sound in the external environment, so that the perception of the surrounding environment can be improved, and important information can be avoided to be missed or accidents can be avoided.

[0051] In some embodiments, asFigure 3 、 Figures 5 to 10 As shown in FIG. 12, the outer peripheral side wall of the sound generating structure 20 abuts against the inner side wall of the cavity, for example, the sound generating structure 20 can be a circular plate, the outer peripheral side wall of the sound generating structure 20 can be a side wall with a curved surface, so that the edge of the sound generating structure 20 can be sealed with the inner side wall of the cavity. A sealing layer can be arranged between the outer peripheral side wall of the sound generating structure 20 and the inner side wall of the cavity to improve the sealing effect. The channel 21 can be arranged at the edge region of the sound generating structure 20, and the edge region of the sound generating structure 20 can be a region on the sound generating structure 20 within a certain distance from the inner side wall of the cavity. The sound generating structure 20 can be a circular plate, and the edge region of the sound generating structure 20 can be a region on the circular surface within a certain distance from the side wall with a curved surface. The channel 21 can be close to the inner side wall of the cavity, facilitating the arrangement of the movable piece 30 and reducing the influence of the movable piece 30 on the sound cavity.

[0052] In some embodiments, the earphone can further include a driving mechanism, which can be used to drive the movable piece 30 to move between the first position and the second position. The driving mechanism can drive the movable piece 30 to block or avoid the channel 21. The driving mechanism can be a driving motor, for example, the driving mechanism can be used to drive the movable piece 30 to move between the first position and the second position, so that the movable piece 30 can block or avoid the channel 21. The driving mechanism can include an electroactive material, which can be deformed under the input of an electric current. The deformation of the electroactive material can drive the movable piece 30 to move, so that the movable piece 30 can block or avoid the channel 21.

[0053] In some embodiments, as shown in FIG. 13, Figure 1 、 Figure 4 、 Figures 6 to 10 The movable piece 30 can include a magnetic part, for example, at least a part of the movable piece 30 can be a magnetic material or the movable piece 30 can have a magnet. The driving mechanism can include an electromagnet 40, and the movable piece 30 can be arranged between the sound generating structure 20 and the electromagnet 40. Under the input of an electric current to the coil of the electromagnet 40, the electromagnet 40 can drive the movable piece 30 to move away from the sound generating structure 20, so that the movable piece 30 can avoid the channel 21. Under the input of an electric current to the coil of the electromagnet 40, the electromagnet 40 has magnetism, and the movable piece 30 has a magnetic part. Through the magnetic force between the electromagnet 40 and the magnetic part of the movable piece 30, the movable piece 30 can be driven to move away from the sound generating structure 20, so that the movable piece 30 can avoid the channel 21.

[0054] In some embodiments, as shown in FIG. 14, Figure 1 、 Figure 4 、 Figures 6 to 10As shown, the driving mechanism can further include an elastic member 50, which can be arranged between the movable member 30 and the electromagnet 40. When the coil of the electromagnet 40 is powered off, the elastic member 50 drives the movable member 30 to move close to the sound generating structure 20, so that the movable member 30 blocks the passage 21. When the coil of the electromagnet 40 is powered on, the electromagnet 40 has magnetism, and the magnetic force between the electromagnet 40 and the magnetic part of the movable member 30 can drive the movable member 30 to move away from the sound generating structure 20. The movable member 30 can deform the elastic member 50, for example, the elastic member 50 is in a compressed state. When the coil of the electromagnet 40 is powered off, the electromagnet 40 has no magnetism, and the elastic member 50 needs to return to the state before deformation. Under the action of the elastic force of the elastic member 50, the movable member 30 moves close to the sound generating structure 20, and the movable member 30 can block the passage 21. When the coil of the electromagnet 40 is powered on, the movable member 30 can move towards the electromagnet 40, and the elastic member 50 has a buffering effect, which can reduce the collision between the electromagnet 40 and the movable member 30. When the coil of the electromagnet 40 is powered off, under the action of the elastic force of the elastic member 50, the movable member 30 moves close to the sound generating structure 20, and the movable member 30 can block the passage 21. The main board can be arranged on the shell 10 and electrically connected with the electromagnet 40. The main board can supply power to the coil of the electromagnet 40 and control the current input into the coil of the electromagnet 40.

The elastic member 50 can be a spring, which can be sleeved on the guide column 32, so that the spring can stably deform. During the recovery of the deformation of the spring, the spring can stably drive the movable member 30 to move close to the sound generating structure 20, so that the movable member 30 can block the passage 21.
