DETAILED DESCRIPTION

[0023] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0024] In the present disclosure, unless otherwise stated, the terms "first", "second", etc. are used to distinguish one element from another element and have no order or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only used to explain and illustrate the present disclosure and should not be understood as limiting the present disclosure.

[0025] According to the specific implementation scheme provided by the present disclosure, Figures 1 to 4 As shown in the figure, a shell assembly is provided, which includes a shell 1, a sound insulation member 2 and a driving structure. The shell 1 is provided with an earpiece hole 11 and a sound outlet hole 12 of a speaker. The shell 1 is formed with a sound channel 13 connecting the earpiece hole 11 and the sound outlet hole 12. The driving structure is fixedly arranged on the shell 1 and is transmission-connected with the sound insulation member 2 to drive the sound insulation member 2 to move between a first position and a second position. In the first position, the sound insulation member 2 avoids the sound outlet hole 12. In the second position, the sound insulation member 2 covers the sound outlet hole 12.

[0026] Through the above technical scheme, in the shell assembly provided by the present invention, the shell 1 is provided with an earpiece hole 11 and a sound outlet hole 12 of a speaker and a sound channel 13 connecting the earpiece hole 11 and the sound outlet hole 12 is formed. The driving structure is transmission-connected to the sound insulation member 2 and can drive the sound insulation member 2 to move between a first position and a second position, that is, to move between a position avoiding the sound outlet hole 12 and a position covering the sound outlet hole 12. In other words, the shell assembly can choose to open or close the sound outlet hole 12 according to different needs of users. When the shell assembly is applied to the technical field of mobile phones, the user can choose to cover the sound outlet hole 12 when using the earpiece to make a call, so that the sound is transmitted from the earpiece hole 11 to avoid leakage of the call content. When the user uses the speaker to play the sound, he can choose to open the sound outlet hole 12, so that the sound is transmitted from both the earpiece hole 11 and the sound outlet hole 12 to improve the sound effect.

[0027] In the shell assembly provided in the present disclosure, as an exemplary embodiment, the shell assembly includes a sealing bracket 43, which is installed on the shell 1 and is arranged in close contact with the sound outlet 12. In the first position, the sound insulator 2 can partially overlap with the sealing bracket 43. In the second position, one end of the sound insulator 2 can stop at the sealing bracket 43 and cut off the connection between the sound outlet 12 and the sound channel 13. That is to say, during the movement of the sound insulator 2 between the first position and the second position, it can be arranged in any suitable manner under the condition of not interfering with the sealing bracket 43. In the present disclosure, the sealing bracket 43 is arranged in close contact with the sound insulator 2 to provide a certain guiding effect for the movement of the sound insulator 2. Among them, the sealing bracket 43 is usually composed of a filter and waterproof silica gel, so as to play a certain waterproof and dustproof effect on the inside of the shell while ensuring the sound effect. In the present disclosure, the shape of the sound insulator 2 can be designed according to the shape of the sealing bracket 43 and the sound outlet 12 to achieve complete covering of the sound outlet 12.

[0028] In the housing assembly provided by the present disclosure, the sound insulation member 2 can be arranged in any suitable manner, and the present disclosure does not impose any specific restrictions on this. As an exemplary embodiment, the housing assembly can include a slide groove 16, which is arranged on the housing 1 or the sealing bracket 43, and the sound insulation member 2 is slidably inserted into the slide groove 16, and the slide groove 16 is used to provide a certain guiding effect for the movement of the sound insulation member 2 between the first position and the second position, thereby improving the stability of the installation and movement of the sound insulation member 2, and preventing the sound insulation member 2 from deviating from the movement path or shaking abnormally.

[0029] Among them, the sliding groove 16 can be constructed in any suitable form, and the present disclosure does not make specific limitations thereto. As an exemplary embodiment, the sliding groove 16 has two opposite side walls, and the two side walls can be respectively abutted against the sound insulation member 2 to guide the movement of the sound insulation member 2. In some other embodiments, the sliding groove 16 can also be constructed as a channel arranged along the movement direction of the sound insulation member 2, and the sound insulation member 2 is inserted into the channel and abutted against the inner wall of the channel, which can also achieve the purpose of guiding the movement of the sound insulation member 2. The present disclosure does not make specific limitations thereto.

[0030] In the housing assembly provided by the present disclosure, the driving structure can drive the sound insulation member 2 in any suitable form, and the present disclosure does not make specific limitations thereto. As an exemplary embodiment, referring to Figure 1 or Figure 2 as shown, the driving structure can include a driving motor 31 and a transmission structure. The driving motor 31 is fixed to the housing 1 and is drivingly connected to the sound insulation member 2 through the transmission structure, so as to convert the power provided by the driving motor 31 into a force for driving the sound insulation member 2 to move in the required direction through the transmission structure.

[0031] Among them, the transmission structure can be constructed in any suitable form, and the present disclosure does not make specific limitations thereto. As an exemplary embodiment, referring to Figure 3 as shown, the driving structure can further include a support seat 32, a limiting member 33 and a coupling member 34. The transmission structure can include a transmission lead screw 35. The transmission lead screw 35 is rotatably installed on the support seat 32 and one end of the transmission lead screw 35 is drivingly connected to the driving motor 31. The sound insulation member 2 is connected to the coupling member 34. The coupling member 34 is inserted through the transmission lead screw 35 and is threadedly connected to the transmission lead screw 35. The limiting member 33 passes through the coupling member 34 and both ends of the limiting member 33 are fixed to the support seat 32. That is to say, the driving motor 31 can be drivingly connected to the transmission lead screw 35 to drive the transmission lead screw 35 to rotate, and then drive the coupling member 34 and the sound insulation member 2 to move along the axial direction of the transmission lead screw 35. Specifically, the output shaft of the driving motor 31 can be coaxially connected to the transmission lead screw 35. Since the coupling member 34 is screwed to the transmission lead screw 35 and the limiting member 33 passes through the coupling member 34 to limit the circumferential rotation of the coupling member 34 along the transmission lead screw 35, in this way, when controlling the driving motor 31 to rotate and then drive the transmission lead screw 35 to rotate, the coupling member 34 can move along the axial direction of the transmission lead screw 35. By controlling the driving motor 31 to rotate forward or backward, the purpose of making the sound insulation member 2 reciprocate along the axial direction of the transmission lead screw 35 is achieved, and further the sound insulation member 2 can shield or avoid the sound outlet hole 12.

[0032] In the present disclosure, the drive motor 31 can be configured as a rotary motor for controlling the rotation of the transmission lead screw 35. In some other embodiments, the drive motor 31 can also be configured as a push-pull motor, and the output shaft of the push-pull motor can be directly connected to the connector 34 without passing through a transmission structure, so as to drive the connector 34 to perform a reciprocating motion in the required direction, and the purpose of shielding or avoiding the sound outlet hole 12 by the sound insulation member 2 can also be achieved.

[0033] In the housing assembly provided by the present disclosure, the support seat 32 can be configured in any suitable form to achieve the purpose of supporting the drive structure and fixing the drive structure to the housing 1, and the present disclosure does not make specific limitations thereto.

In this way, on the one hand, the support seat 32 can provide an installation space for the arrangement of the transmission lead screw 35 and the limiting member 33, and on the other hand, the drive structure is fixed to the housing 1 through the support seat 32, improving the reliability of the installation between the two. In addition, in some other embodiments, the support seat 32 can also be directly fixed to the housing 1 by means of pasting, welding, etc., and the present disclosure does not make specific limitations thereto.

[0034] In the housing assembly provided by the present disclosure, the sound insulation member 2 and the connector 34 can be connected in any suitable manner, such as bonding, snap connection or connection by fasteners, etc., and the present disclosure does not make specific limitations thereto. As an exemplary embodiment, referring to Figure 3 as shown in, one of the sound insulation member 2 and the connector 34 can be provided with a connection hole 21, and the other of the sound insulation member 2 and the connector 34 can be provided with a connection pin shaft, and the connection pin shaft is inserted into the connection hole 21 to enable the fixation of the sound insulation member 2 and the connector 34. The fitting connection manner between the connection pin shaft and the connection hole 21 is not only simple to install, but also can effectively prevent the disconnection between the connector 34 and the sound insulation member 2.

[0035] In the housing assembly provided by the present disclosure, as an exemplary embodiment, referring to Figure 4 as shown in, the housing 1 includes a middle frame 41 and a plate body 42, the middle frame 41 surrounds the edge of the plate body 42 and is connected to the edge of the plate body 42, and the sound outlet hole 12 can be provided on the middle frame 41. Among them, the middle frame 41 is used to provide a supporting effect for the plate body 42, and the speaker is installed on the plate body, so that the emitted sound can pass through the sound channel 13 and be transmitted to the middle frame 41, that is, the outside of the electronic device, through the sound outlet hole 12.

[0036] In the housing assembly provided by the present disclosure, as an exemplary embodiment, referring to Figure 4As shown, the board body is formed with a mounting portion 15, and the driving structure can be mounted on the mounting portion 15. The housing 1 assembly further includes a cover plate 5, and the cover plate 5 can be fixedly mounted on the board body 42 and cover the mounting portion 15. Among them, the mounting portion 15 can be configured as a groove formed by being recessed from the surface of the board body 42. When the cover plate 5 covers the mounting portion 15, on the one hand, it can make the surface of the middle frame 41 flat, avoiding affecting the supporting effect of the board body 42 on other electronic components such as the screen. On the other hand, it can further improve the sealing performance of the electronic device, preventing water, dust, etc. from entering through the sound outlet hole 12 and affecting the service life of other electronic components. In addition, the cover plate 5 can be installed and fixed to the board body 42 in any suitable manner. In the present disclosure, the shape of the cover plate 5 matches the shape of the mounting portion 15, and it can be fixed to the board body 42 by snap connection. During installation, just align the board body 42 with the mounting portion 15 and press, then the fixation between the cover plate 5 and the board body 42 can be achieved. The present disclosure does not make specific limitations on this either. In addition, the cover plate 5 can also be connected to the board body 42 through fasteners such as bolts and screws, or connected to the board body 42 by bonding.
