Referring to fig. 1, fig. 1 is an exploded schematic view of a first embodiment of a housing assembly 10 provided in the present application, where the housing assembly 10 of the present embodiment includes a middle frame 11, a decoration 12 and a driving assembly 13.

Referring to fig. 2, fig. 2 is a schematic cross-sectional view of the middle frame 11 and the decoration 12 in fig. 1, in which the middle frame 11 is opened with a sound outlet groove 111, and the sound outlet groove 111 has a sound outlet direction as indicated by an arrow in fig. 2.

The decoration 12 is movably disposed on the sound emitting side of the sound emitting groove 111, and specifically, the decoration 12 moves in a sound emitting direction parallel to the sound emitting groove 111 to open or close the sound emitting groove 111. As shown in fig. 2, the garnish 12 is located substantially at a position where the sound emitting groove 111 is closed.

It is understood that the sound output side is a side from which sound is output through the sound output groove 111.

The driving component 13 is connected to the middle frame 11 and is used for generating magnetic attraction force or magnetic repulsion force, so as to drive the decoration 12 to open or close the sound outlet groove 111 on the sound outlet side.

The driving element 13 can directly or indirectly drive the decoration 12, and in this embodiment, the driving element 13 directly drives the decoration 12 is taken as an example for description. Specifically, the driving assembly 13 includes an electromagnetic induction coil, and the electromagnetic induction coil is connected to the middle frame 11. The electromagnetic induction coil is used for generating magnetic force, and the direction of the magnetic force is parallel to the sound outlet direction of the sound outlet groove 111.

Specifically, the decoration 12 is a magnet, and the electromagnetic induction coil cooperates with the magnet to generate a magnetic attraction force or a magnetic repulsion force to drive the decoration 12 to move relative to the middle frame 11, so that the decoration 12 moves relative to the middle frame 11 in a direction parallel to the sound emitting direction.

Further, the electromagnetic induction coil is disposed on the middle frame 11 and is opposite to the decoration 12 in the direction of the generated magnetic force, so that after the electromagnetic induction coil is energized to generate the magnetic force, the magnetic force drives the decoration 12 to move in the direction parallel to the sound emitting direction, thereby opening or blocking the sound emitting groove 111.

In some embodiments, when the current direction inside the electromagnetic induction coil is clockwise, a magnetic attraction force is generated between the electromagnetic induction coil and the decoration piece; when the current direction in the electromagnetic induction coil is anticlockwise, magnetic repulsive force is generated between the electromagnetic induction coil and the decorating part.

Of course, in other embodiments, when the current direction inside the electromagnetic induction coil is counterclockwise, a magnetic attraction force is generated between the electromagnetic induction coil and the decoration; when the current direction in the electromagnetic induction coil is clockwise, magnetic repulsion force is generated between the electromagnetic induction coil and the decorating part.

As shown in fig. 3, fig. 3 is a schematic diagram showing the movement of the garnish 12 in fig. 1 with respect to the center 11, and when a magnetic repulsive force is generated between the electromagnetic induction coil and the garnish 12, the magnetic repulsive force drives the garnish 12 to move in the direction indicated by the arrow in fig. 3 on the sound-emitting side to open the sound-emitting slot 111. When a magnetic attraction force is generated between the electromagnetic induction coil and the decoration 12, the magnetic attraction force drives the decoration 12 to move in a direction opposite to an arrow shown in fig. 3 on the sound emitting side to block the sound emitting groove 111. As shown in fig. 3, the garnish 12 is located substantially at a position where the sound emitting groove 111 is opened.

Referring to fig. 4 and 5 together, fig. 4 is a schematic structural diagram of sound outlet groove 111 according to some embodiments of the present application, and fig. 5 is a schematic structural diagram of decorative element 12 according to some embodiments of the present application. The side wall of the sound outlet groove 111 is provided with a sliding groove 1111, and the decoration 12 moves relative to the middle frame 11 along the sliding groove 1111.

The sliding grooves 1111 are opened on the opposite side walls of the sound outlet groove 111, that is, two sliding grooves 1111 are generally opened and located at the corresponding positions of the opposite side walls. For example, the sound emitting slot 111 may have a long side wall with a large area and disposed oppositely and a short side wall with a small area and disposed oppositely, and the sliding slot 1111 may be disposed on the long side wall with an opposite side wall or the short side wall with an opposite side wall. In the embodiment of the present application, the sliding groove 1111 is disposed on the short side wall disposed opposite to the short side wall, that is, the sliding groove 1111 is opened at the corresponding position of the short side wall disposed opposite to the sound outlet groove 111.

Of course, in other embodiments, the sliding grooves 1111 may be opened on the side walls of the sound outlet groove 111 to enhance the stability of the decoration 12 moving relative to the middle frame 11.

Further, the decoration 12 generally includes a body portion 121 and a sliding portion 122, and the sliding portion 122 is engaged with the sliding slot 1111 to move the body portion 121 relative to the middle frame 11. The sliding portions 122 are disposed corresponding to the sliding grooves 1111, that is, when the decoration 12 is assembled with the middle frame 11, each sliding portion 122 has a corresponding sliding groove 1111, and the corresponding sliding portion 122 is slidably connected to the sliding groove 1111. Specifically, the correspondence relationship between the main body 121 and the sliding portion 122 of the garnish 12 can refer to the correspondence relationship between the chute 1111 and the sound emitting groove 111. In the embodiment of the present application, two sliding portions 122 are provided, and are slidably connected to the two sliding grooves 1111 respectively.

Referring again to fig. 2 to 5, the side wall of the sound exit groove 111 is disposed obliquely in the sound exit direction of the sound exit groove 111, and the cross-sectional area of the sound exit groove 111 gradually increases along the sound exit direction. That is, the area of the end of the sound outlet groove 111 close to the electromagnetic induction coil is smaller than the area of the end of the sound outlet groove 111 far away from the electromagnetic induction coil. In other words, the sound outlet groove 111 is substantially a trapezoid structure, the upper bottom surface of the trapezoid is disposed on the inner sidewall of the middle frame 11, and the lower bottom surface of the trapezoid is disposed on the outer sidewall of the middle frame 11, so as to form a trapezoid structure in which the cross-sectional area of the sound outlet groove 111 gradually increases in the sound outlet direction.

It can be understood that the sound outlet groove 111 is substantially in a horn structure along the sound outlet direction, which is beneficial to enhancing the sound effect. The decoration member 12 is accommodated in the sound outlet groove 111, and moves in the sound outlet groove 111 to open or close the sound outlet groove 111.

Specifically, the garnish 12 is similar to the shape of the sound emitting groove 111, i.e., the garnish 12 is contoured with reference to the sound emitting groove 111. The ornamental member 12 is also substantially trapezoidal in configuration to facilitate opening or closing of the sound outlet channel 111 as the ornamental member 12 moves within the sound outlet channel 111.

Further, the width of the garnish 12 in the sound-emitting direction is smaller than the depth of the sound-emitting groove 111 in the sound-emitting direction. Specifically, in the direction along the sound emitting direction, the garnish 12 has a width L, and the sound emitting groove 111 has a depth H, wherein the width L < the depth H. Preferably, the width L is less than or equal to 1/2 and the depth H is designed to allow the decorative element 12 to have a certain movement space in the sound outlet groove 111.

It can be understood that in the present embodiment, the decoration 12 is used to open or close the sound groove 111, and when the decoration 12 closes the sound groove 111, the end of the decoration 12 close to the electromagnetic coil completely covers the corresponding end of the sound groove 111.

Furthermore, the sound outlet groove 111 is opened or sealed by the decoration part 12, so that not only can the function of preventing dust be achieved, but also water vapor can be prevented from entering the electronic equipment, and the service life of the electronic equipment is further influenced. When the sound outlet groove 111 is opened by the decoration 12, the sound outlet groove 111 is in a sound state, so that airflow is blown to the outside of the electronic device, and dust and moisture are difficult to enter the inside of the electronic device. When the decorative member 12 blocks the sound groove 111, the passage of dust and moisture into the inside of the electronic apparatus is blocked.

The casing subassembly that this embodiment provided, through electromagnetic induction coil and magnet cooperation production magnetic attraction or magnetism repulsive force to drive the decoration and open or shutoff sound groove in the sound side of going out of sound groove, make sound groove when not using, this sound groove of going out is closed, and when using, sound groove just can be opened, prevents that external dust and steam from getting into electronic equipment inside through sound groove of going out, has improved the sound effect. In addition, when the sound outlet groove is used, the middle frame is communicated with the external space, and vibration caused by sound wave transmission of the closed space can be weakened or eliminated.

The driving element 23 can directly or indirectly drive the decoration 12, and in the present embodiment, the driving element 23 directly drives the decoration 12 is taken as an example for description. Specifically, the first driving member 231 and the second driving member 232 are electromagnetic induction coils. The first driving member 231 is disposed on the middle frame 11 and connected to the middle frame 11. The second driving member 232 is disposed on the decoration 12 and connected to the decoration 12. The electromagnetic induction coil is used for generating magnetic force, and the direction of the magnetic force is parallel to the sound outlet direction of the sound outlet groove 111.

In other embodiments, the second driving member 232 may be disposed at an end of the decoration element 12 close to the first driving member 231, or the second driving member 232 may be disposed around the decoration element 12.

Specifically, the first driving member 231 and the second driving member 232 are disposed opposite to each other in a direction in which the magnetic force is generated. The first driving element 231 is used for generating a first magnetic force, the second driving element 232 is used for generating a second magnetic force, and the first magnetic force and the second magnetic force are matched to drive the decorating part 12 to move in a direction parallel to the sound emitting direction, so that the sound emitting groove 111 is opened or closed. That is, the first magnetic force and the second magnetic force may be a magnetic attractive force or a magnetic repulsive force therebetween, so as to drive the decoration 12 to move relative to the center frame 11 in a direction parallel to the sound emitting direction.

It can be understood that when the current directions in the first driving member 231 and the second driving member 232 are the same, a magnetic attraction force is generated between the first driving member 231 and the second driving member 232; when the current directions in the first driving element 231 and the second driving element 232 are different, a magnetic repulsive force is generated between the first driving element 231 and the second driving element 232.

As shown in fig. 8, the garnish 12 is located substantially at a position where the sound emitting groove 111 is opened. When a magnetic attraction force is generated between the first driving member 231 and the second driving member 232, the magnetic attraction force drives the decoration 12 to move in a direction opposite to the direction indicated by the arrow in fig. 8 on the sound outlet side to block the sound outlet groove 111. As shown in fig. 7, the garnish 12 is located substantially at a position where the sound emitting groove 111 is closed.

It is understood that reference may be made to the first embodiment regarding the structural features of the garnish 12 and the sound exit groove 111, and the description of this embodiment will not be repeated.

In the embodiment of the present application, the decoration element 12 is made of a flexible material, for example, the decoration element 12 may be made of a flexible material such as rubber, silicon gel, etc., so as to provide a better sealing property when the sound groove 111 is sealed.

Referring to fig. 9, fig. 9 is an exploded schematic view of a third embodiment of a housing assembly 30 provided in the present application, in which the housing assembly 30 of the present embodiment includes a middle frame 11, a decoration 12 and a driving assembly 33; the driving assembly 33 includes a first driving member 331, a second driving member 332, and a third driving member 333.

Referring to fig. 10, fig. 10 is a schematic cross-sectional view illustrating the middle frame 11 and the decoration 12 in fig. 9, the middle frame 11 is opened with a sound outlet groove 111, and the sound outlet groove 111 has a sound outlet direction as indicated by an arrow in fig. 10.

The decoration 12 is movably disposed on the sound emitting side of the sound emitting groove 111, and specifically, the decoration 12 moves in a sound emitting direction parallel to the sound emitting groove 111 to open or close the sound emitting groove 111. As shown in fig. 10, the garnish 12 is located substantially at a position where the sound emitting groove 111 is closed.

The first driving member 331 is connected to the middle frame 11, the second driving member 332 is connected to the garnish 12, and the third driving member 333 is connected to the middle frame 11 or the garnish 12. The first driving element 331, the second driving element 332 and the third driving element 333 are coupled to generate a magnetic attraction force or a magnetic repulsion force, so as to drive the decoration 12 to open or close the sound outlet groove 111 at the sound outlet side.

The driving element 33 can directly or indirectly drive the decoration 12, and in the present embodiment, the driving element 33 directly drives the decoration 12 is taken as an example for description. Specifically, the first driving member 331 and the second driving member 332 are both magnets, and the third driving member 333 is an electromagnetic induction coil. The first driving member 331 is disposed on the middle frame 11 and connected to the middle frame 11. The second driving member 332 is disposed on the decoration 12 and connected to the decoration 12. The third driving member 333 is provided on the center frame 11 or on the garnish 12. Preferably, the third driving member 333 is disposed on the middle frame 11 and connected to the middle frame 11, wherein the electromagnetic coil of the third driving member 333 is used to generate a magnetic force, and the direction of the magnetic force is parallel to the sound output direction of the sound output slot 111.

In other embodiments, the second driving element 332 may be disposed at an end of the decoration 12 near the first driving element 331, or the second driving element 332 may be disposed around the decoration 12, or the second driving element 332 may be disposed inside the decoration 12.

Specifically, the first driver 331 and the second driver 332 are disposed opposite to each other in the magnetic force direction. The first driving element 331 and the second driving element 332 attract each other to enable the decorating piece 12 to close the sound groove 111. The magnetic force generated by the third driving member 333 drives the decoration 12 to move so that the decoration 12 opens the sound emitting slot 111.

As shown in fig. 11, fig. 11 is a schematic diagram of the movement of the trim 12 in fig. 9 relative to the middle frame 11, wherein a magnetic attraction force F1 is generated between the first driving element 331 and the second driving element 332, and a magnetic repulsion force F2 is generated between the third driving element 333 and the second driving element 332. When the magnetic attraction force F1 > the magnetic repulsion force F2, the garnish 12 moves relative to the center frame 11 and blocks the sound groove 111, and as shown in fig. 10, the garnish 12 is located substantially at a position where the sound groove 111 is blocked. When the magnetic attraction force F1 < the magnetic repulsion force F2, the garnish 12 moves relative to the center frame 11 and closes the sound groove 111, and as shown in fig. 11, the garnish 12 is located substantially at a position closing the sound groove 111.

Specifically, when the third driving element 333 is not energized and does not generate magnetic force, the magnetic attraction force F1 generated between the first driving element 331 and the second driving element 332 causes the garnish 12 to assume the initial state shown in fig. 10, i.e., the garnish 12 blocks the sound slot 111, at this time, the third driving element 333 is energized to generate the magnetic repulsion force F2, the magnetic repulsion force F2 causes the garnish 12 to move to the right as shown in fig. 11 until the garnish 12 opens the sound slot 111, and further, when the third driving element 333 is not energized to generate the magnetic repulsion force F2, the garnish 12 moves to the left as shown in fig. 11 under the action of the magnetic attraction force F1 and returns to the state shown in fig. 10 where the garnish 12 blocks the sound slot 111.

For example, when the user selects to play the external sound, the sound sensor module of the electronic device converts the received sound signal into an electrical signal, and then controls the driving component to be powered on, i.e. the third driving element 333 to be powered on, so as to generate a magnetic repulsive force opposite to the direction of the magnetic attractive force between the first driving element 331 and the second driving element 332, and further drive the decoration 12 to move to open the sound outlet slot 111. When the user stops playing the external sound, the third driving member 333 is powered off, and the magnetic attraction between the first driving member 331 and the second driving member 332 drives the decoration 12 to move to close the sound outlet 111.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present application are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

Further, when the magnetic repulsive force F2 generated by the third driving element 333 being energized is the same as the magnetic attractive force F1 generated between the first driving element 331 and the second driving element 332, the garnish 12 maintains the state of opening or closing the sound slot 111.

As shown in fig. 13, the garnish 12 is located substantially at a position where the sound emitting groove 111 is closed.

The first driving member 431 is connected to the middle frame 11, the second driving member 432 is connected to the garnish 12, and the third driving member 433 is used to connect the middle frame 11 to the garnish 12. The first driving element 431, the second driving element 432 and the third driving element 433 are matched to generate magnetic attraction or magnetic repulsion, so that the decorative piece 12 can be driven to open or close the sound outlet groove 111 on the sound outlet side.

The driving element 43 can directly or indirectly drive the decoration 12, and in the present embodiment, the driving element 43 directly drives the decoration 12 is taken as an example for description. Specifically, the first driving member 431 is an electromagnetic coil, the second driving member 432 is a magnet, and the third driving member 433 is a spring. The first driving member 431 is disposed on the middle frame 11 and connected to the middle frame 11. The second driving member 432 is provided on the garnish 12 and connected to the garnish 12. The third driver 433 connects the middle frame 11 and the garnish 12. The electromagnetic coil of the first driving member 431 is used for generating a magnetic force, and the direction of the magnetic force is parallel to the sound emitting direction of the sound emitting slot 111, and the third driving member 333 is used for generating an elastic force opposite to the direction of the magnetic force, and the direction of the elastic force is parallel to the sound emitting direction of the sound emitting slot 111.

In other embodiments, the second driving element 432 may be disposed at an end of the decoration 12 near the first driving element 431, or the second driving element 432 may be disposed around the decoration 12, or the second driving element 432 may be disposed inside the decoration 12.

Specifically, the first driving element 431 and the second driving element 432 are disposed opposite to each other in the magnetic direction, so that when the electromagnetic induction coil is energized to generate a magnetic force, the magnetic force drives the decoration 12 to move in a direction parallel to the sound emitting direction, thereby opening or closing the sound emitting slot 111.

As shown in fig. 14, fig. 14 is a schematic diagram of the movement of the decoration 12 in fig. 12 relative to the middle frame 11, a magnetic force F3 is generated between the first driving member 431 and the second driving member 432, and the magnetic force F3 may be a magnetic attraction force or a magnetic repulsion force. The third driving member 433 generates a spring force F4 opposite to the direction of the magnetic force F3. The direction of the elastic force generated by the third driving member 433 is parallel to the sound emitting direction of the sound emitting groove 111, so that the garnish 12 moves relative to the center frame 11 in the direction parallel to the sound emitting direction. Alternatively, the elastic force generated by the third driving member 433 may be an elastic force generated by compression or an elastic force generated by extension.

The magnetic force F3 may be a magnetic attractive force when the elastic force F4 generated by the third driver 433 is an elastic force generated by compression, and the magnetic force F3 may be a magnetic repulsive force when the elastic force F4 generated by the third driver 433 is an elastic force generated by extension, which is exemplified by the elastic force F4 generated by the third driver 433 in the illustration of the present embodiment.

Wherein, the magnetic force F3 is greater than or equal to the preset threshold value, so that under the action of the elastic force F4, the magnetic force drives the decoration 12 to move.

It will be appreciated that since the magnetic force F3 is opposite to the spring force F4, the spring force F4 must be overcome to move the garnish 12 when the magnetic force F3 moves the garnish 12.

Further, the elastic force generated by the third driving member 433 cooperates with the magnetic force generated between the first driving member 431 and the second driving member 432 to drive the decoration 12 to open or close the sound outlet groove 111 at the sound outlet side of the sound outlet groove 111.

Specifically, when the first driving member 431, i.e., the electromagnetic coil, is not energized and does not generate magnetic force, the third driving member 433, i.e., the spring, generates elastic force to make the decoration 12 in the initial state as shown in fig. 13, i.e., the decoration 12 blocks the sound slot 111, at this time, the electromagnetic coil is energized to generate magnetic force, the magnetic force makes the decoration 12 move to the right as shown in fig. 13 until the decoration 12 opens the sound slot 111 as shown in fig. 14, and further, when the electromagnetic coil is not energized to generate magnetic force, the decoration 12 moves to the left as shown in fig. 14 under the elastic force of the spring and returns to the state that the decoration 12 blocks the sound slot 111 as shown in fig. 13.

It should be understood that the initial state may be a state where the sound emitting groove 111 is opened by the garnish 12, and further, after the electromagnetic induction coil is energized to generate a magnetic force, the garnish 12 is driven to close the sound emitting groove 111.

Optionally, when the magnetic force generated by the electromagnetic coil is equal to the elastic force generated by the spring, the decoration 12 maintains the state of opening or closing the sound groove 111. That is, after the magnetic force generated by the electromagnetic induction coil drives the decoration 12 to open or close the sound outlet groove 111, the magnetic force is equal to the elastic force generated by the spring at this time, so that the decoration 12 stops moving, and no other structure is needed to stop the decoration 12 in the moving direction of the decoration 12.
