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 first decoration 12, a spring 13, and an electromagnetic coil 14.

Referring to fig. 2, the middle frame 11 is provided with a sound outlet channel 111, the sound outlet channel 111 has a sound outlet direction as indicated by an arrow in fig. 2, and further, the middle frame 11 is further provided with a through hole 112.

The first decoration 12 is movably disposed on the sound outlet side of the sound outlet channel 111, specifically, the first decoration 12 includes a decoration portion 121 and a force receiving portion 122, the decoration portion 121 is disposed opposite to the middle frame 11 on the sound outlet side of the sound outlet channel 111, and the force receiving portion 122 is connected to the decoration portion 121 and extends to one side of the middle frame 11 far away from the decoration portion 121 through the through hole 112.

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

Wherein, decorative portion 121 is provided with a first sound outlet 1211, and the number of the first sound outlet 1211 can be one or more; optionally, one end of the force-bearing part 122 away from the decoration part 121 is bent, and the number of the force-bearing parts is two.

Referring to fig. 3 and 4 together, the spring 13 is connected to the middle frame 11 and can generate an elastic force to drive the first decoration member 12 to move relative to the middle frame 11.

Specifically, the housing assembly 10 of the present embodiment further includes a connecting member 15, the spring 13 is disposed on one side of the middle frame 11 away from the decoration portion 121, and two ends of the spring 13 are respectively connected to the middle frame 11 and the connecting member 15, so that the elastic force generated by the spring 13 can drive the connecting member 15 to move relative to the middle frame 11, and further, the connecting member 15 is connected to the first decoration 12, so that the connecting member 15 drives the first decoration 12 to move when moving.

Specifically, as shown in fig. 4, the connecting member 15 includes a first portion 151 and a second portion 152, the first portion 151 is connected to one end of the spring 13, the connection may be an abutting connection or a fixed connection in other manners, the second portion 152 is bent and forms a clamping gap 1521 as shown in fig. 4, the force receiving portion 122 of the first decorative portion 12 is inserted into the clamping gap 1521, so that the connecting member 15 is connected to the first decorative portion 12, and the first decorative portion 12 is driven to move when the connecting member 15 is driven by the above-mentioned elastic force.

Optionally, the number of the second portions 152 is two, and the two second portions are respectively connected to the two force receiving portions 122.

It is understood that in other embodiments, the spring 13 can be directly connected to the force-receiving portion 122 of the first decoration 12 to directly drive the first decoration 12 to move relative to the middle frame 11.

Referring further to fig. 3, the direction of the elastic force generated by the spring 13 is perpendicular to the sound emitting direction of the sound emitting channel 111, so that the first decoration 12 moves relative to the middle frame 11 in the direction perpendicular to the sound emitting direction.

Alternatively, the elastic force generated by the spring 13 may be an elastic force generated by compression or an elastic force generated by extension.

Referring to fig. 5, the electromagnetic coil 14 is used for generating a magnetic force opposite to the elastic force direction to drive the first decoration 12 to move relative to the middle frame 11, and the direction of the magnetic force is perpendicular to the sound emitting direction of the sound emitting channel 111, so that the first decoration 12 moves relative to the middle frame 11 in the direction perpendicular to the sound emitting direction.

Specifically, the electromagnetic induction coil 14 is disposed on one side of the middle frame 11 away from the decoration part 121, and is disposed opposite to the connecting member 15 in the direction of the generated magnetic force, so that after the electromagnetic induction coil 14 is energized to generate magnetic force, the magnetic force attracts the driving connecting member 15 to move the driving connecting member 15 in the direction opposite to the direction of the elastic force generated by the spring 13, and further drives the first decoration 12 to move.

Here, when the elastic force of the spring 13 is the elastic force generated by compression, the electromagnetic induction coil 14 is disposed on the same side of the connecting member 15 and the spring 13, and when the elastic force of the spring 13 is the elastic force generated by extension, the electromagnetic induction coil 14 is disposed on the side of the connecting member 14 away from the spring 13, and in the embodiment, the elastic force generated by the spring 13 is taken as the elastic force generated by compression as an example.

Alternatively, the number of the electromagnetic induction coils 14 is two, and the two electromagnetic induction coils are respectively arranged opposite to the two second portions 152 so as to attract the second portions 152 when the magnetic force is generated.

Wherein, the magnetic force generated by the electromagnetic induction coil 14 is greater than or equal to a preset threshold value, so that under the action of the elastic force, the magnetic force drives the first decoration 12 to move.

It will be appreciated that since the magnetic force generated by the electromagnetic coil 14 is opposite to the elastic force generated by the spring 13, the first decorative element 12 needs to be driven to move against the elastic force when the first decorative element 12 is driven to move by the magnetic force.

Referring to fig. 6 and 7 together, the elastic force generated by the spring 13 cooperates with the magnetic force generated by the electromagnetic coil 14 to drive the first decoration 12 to open or close the sound outlet channel 111 at the sound outlet side of the sound outlet channel 111.

Specifically, the housing assembly 10 of the present embodiment further includes a second garnish 16, and the second garnish 16 is disposed in a manner corresponding to the sound outlet channel 111 on the sound outlet side of the sound outlet channel and is stacked on the garnish portion 121 of the first garnish 12.

The second decoration 16 has a second sound outlet hole 161, and when the first decoration 12 is driven by the elastic force and the magnetic force, the first sound outlet hole 1211 overlaps or is staggered with the second sound outlet hole 161, so as to open or close the sound outlet channel 111.

Specifically, when the electromagnetic coil 14 is not energized and does not generate magnetic force, the elastic force generated by the spring 13 makes the first ornament 12 assume the initial state as shown in fig. 6, and if the initial state is a state in which the first sound outlet 1211 and the second sound outlet 161 are dislocated, the first decoration element 12 and the second decoration element 16 close the sound outlet channel 111 together, at this time, the electromagnetic induction coil 14 is electrified to generate magnetic force, the magnetic force attracts the first decoration 12 to move leftward as shown in fig. 6 until the first sound outlet 1211 and the second sound outlet 161 are overlapped as shown in fig. 7, so that the first decoration 12 and the second decoration 16 open the sound outlet channel 111 together, when the electromagnetic coil 14 is not energized to generate a magnetic force, the first garnish 12 moves rightward as shown in fig. 7 by the elastic force of the spring 13, and returns to a state where the first sound emission hole 1211 and the second sound emission hole 161 are misaligned as shown in fig. 6.

It is understood that the initial state may be a state where first sound emitting hole 1211 and second sound emitting hole 161 are overlapped to open sound emitting channel 111, and after electromagnetic induction coil 14 is energized to generate magnetic force, first sound emitting hole 1211 and second sound emitting hole 161 are in a staggered state to close sound emitting channel 111.

Optionally, when the sound outlet channel 111 is opened or closed, the magnetic force generated by the electromagnetic induction coil 14 is equal to the elastic force generated by the spring 13, that is, after the magnetic force generated by the electromagnetic induction coil 14 drives the first decoration 12 to open or close the sound outlet channel 111, the magnetic force is equal to the elastic force generated by the spring 13 at this time, so that the first decoration 12 stops moving, and no other structure is needed to stop the first decoration 12 in the moving direction of the first decoration 12. The casing subassembly that this embodiment provided, the elasticity that produces through the spring and the magnetic force that the electromagnetic induction coil produced cooperate to drive first decoration and open or closed sound channel in sound channel's play sound side, make sound channel when not using, this sound channel is closed, and when using, sound channel just can be opened, prevents that external dust from getting into mobile terminal inside through sound channel, has improved the sound effect.

The middle frame 11 is provided with a sound outlet channel 111, and further, the middle frame 11 is further provided with a through hole 112.

The first decoration 12 is movably disposed on the sound outlet side of the sound outlet channel 111, specifically, the first decoration 12 includes a decoration portion 121 and a force receiving portion 122, the decoration portion 121 is disposed opposite to the middle frame 11 on the sound outlet side of the middle frame 11, and the force receiving portion 122 is connected to the decoration portion 121 and extends to one side of the middle frame 11 far away from the decoration portion 121 through the through hole 112.

Foam 21 is attached to the center frame and can provide a spring force to move first garnish 12 relative to center frame 11.

Referring to fig. 9, the foam 21 may directly or indirectly drive the first decoration element 12, in this embodiment, the foam 21 indirectly drives the first decoration element 12 is taken as an example for description, specifically, the housing assembly 20 of this embodiment further includes a connecting element 15, the foam 21 is disposed on one side of the middle frame 11 away from the decoration portion 121, and two ends of the foam are respectively connected to the middle frame 11 and the connecting element 15, so that the elastic force generated by the foam 21 can drive the connecting element 15 to move relative to the middle frame 11, and further, the connecting element 15 is connected to the force receiving portion 122 of the first decoration element 12, so that the connecting element 15 drives the first decoration element 12 to move when moving.

Specifically, the connecting member 15 includes a first portion 151 and a second portion 152, the first portion 151 is connected to one end of the foam 21, the connection may be an abutment or a fixed connection in other manners, the second portion 152 is bent to form a clamping gap 1521, the force receiving portion 122 of the first decorative portion 12 is inserted into the clamping gap 1521, so that the connecting member 15 is connected to the first decorative portion 12, and the first decorative portion 15 is driven to move when the elastic force drives the connecting member 15.

It is understood that in other embodiments, foam 21 may be directly connected to force-receiving portion 122 of first decorative element 12 to directly drive first decorative element 12 to move relative to middle frame 11.

Wherein, the direction of the elastic force generated by the foam 21 is perpendicular to the sound emitting direction of the sound emitting channel 111, so that the first decoration 12 moves relative to the middle frame 11 in the direction perpendicular to the sound emitting direction.

Alternatively, the elastic force generated by the foam 21 may be an elastic force generated by compression or an elastic force generated by stretching.

The electromagnetic coil 14 is used to generate a magnetic force opposite to the above-mentioned elastic force direction to drive the first decoration 12 to move relative to the middle frame 11, and as can be understood, the magnetic force is perpendicular to the sound output direction of the sound output channel 111, so that the first decoration 12 moves relative to the middle frame 11 in a direction perpendicular to the sound output direction.

Specifically, the electromagnetic induction coil 14 is disposed on one side of the middle frame 11 away from the decoration part 121, and is disposed opposite to the connecting member 15 in the direction of the generated magnetic force, so that after the electromagnetic induction coil 14 is energized to generate magnetic force, the magnetic force attracts the driving connecting member 15 to drive the connecting member 15 to move in the direction opposite to the direction of the elastic force generated by the foam 21, and further drives the first decoration 12 to move.

Wherein, when the elastic force of the foam 21 is the elastic force generated by compression, the electromagnetic induction coil 14 is disposed on the same side of the connecting member 15 and the foam 21, and when the elastic force of the foam 21 is the elastic force generated by stretching, the electromagnetic induction coil 14 is disposed on the side of the connecting member 14 away from the foam 21, in this embodiment, the elastic force generated by the foam 21 is taken as the elastic force generated by compression.

It can be understood that, since the magnetic force generated by the electromagnetic coil 14 is opposite to the elastic force generated by the foam 21, when the first decoration 12 is driven to move by the magnetic force, the elastic force needs to be overcome to drive the first decoration 12 to move.

Further, the elastic force generated by the foam 21 cooperates with the magnetic force generated by the electromagnetic coil 14 to drive the first decoration 12 to open or close the sound outlet channel 111 at the sound outlet side of the sound outlet channel 111.

Specifically, the housing assembly 20 of the present embodiment further includes a second garnish 16, and the second garnish 16 is disposed in a manner of being stacked on the decoration portion 121 of the first garnish 12, and is disposed corresponding to the sound outlet channel 111 on the sound outlet side of the sound outlet channel 111.

Specifically, when the electromagnetic induction coil 14 is not energized and does not generate magnetic force, the elastic force generated by the foam 21 makes the first decoration 12 in an initial state, and if the initial state is a state where the first sound outlet 1211 and the second sound outlet 161 are misaligned, the first decoration 12 and the second decoration 16 close the sound outlet channel 111 together, at this time, the electromagnetic induction coil 14 is energized to generate magnetic force, the magnetic force attracts the first decoration 12 to move until the first sound outlet 1211 and the second sound outlet 161 coincide, the first decoration 12 and the second decoration 16 open the sound outlet channel 111 together, and further when the electromagnetic induction coil 14 is not energized and does not generate magnetic force, the first decoration 12 moves in the elastic force direction under the elastic force of the foam 21 to return to the initial state, that is, the first sound outlet 1211 and the second sound outlet 161 are misaligned.

Optionally, when the sound outlet channel 111 is opened or closed, the magnetic force generated by the electromagnetic induction coil 14 is equal to the elastic force generated by the foam 21, that is, after the magnetic force generated by the electromagnetic induction coil 14 drives the first decoration 12 to open or close the sound outlet channel 111, the magnetic force is equal to the elastic force generated by the foam 21 at this time, so that the first decoration 12 stops moving, and no other structure is needed to stop the first decoration 12 in the moving direction of the first decoration 12. The casing subassembly that this embodiment provided, the elasticity that produces through the bubble cotton and the magnetic force that the electromagnetic induction coil produced cooperate to drive first decoration and open or closed sound channel in sound channel's play sound side, make sound channel when not using, this sound channel is closed, and when using, sound channel just can be opened, prevents that external dust from getting into mobile terminal inside through sound channel, has improved a sound effect.

Wherein, the direction of the elastic force generated by the elastic part 312 is perpendicular to the sound emitting direction of the sound emitting channel 111, so that the first decoration 12 moves relative to the middle frame 11 in the direction perpendicular to the sound emitting direction.

Alternatively, the elastic force generated by the elastic portion 312 may be an elastic force generated by compression or an elastic force generated by extension.

The electromagnetic coil 14 is configured to generate a magnetic force opposite to the elastic direction, so as to drive the connecting member 31 and further drive the first decoration 12 to move relative to the middle frame 11, and the direction of the magnetic force is perpendicular to the sound output direction of the sound output channel 111, so that the first decoration 12 moves relative to the middle frame 11 in the direction perpendicular to the sound output direction.

Specifically, the electromagnetic induction coil 14 is disposed opposite to the connecting member 31 in the direction of the generated magnetic force, so that after the electromagnetic induction coil 14 is energized to generate the magnetic force, the magnetic force attracts the driving connecting member 31 to drive the connecting member 31 to move in the direction opposite to the direction of the elastic force generated by the elastic portion 312, thereby driving the first decoration member 12 to move.

When the elastic force of the elastic portion 312 is the elastic force generated by compression, the electromagnetic induction coil 14 is disposed on the same side of the connecting member 31 as the elastic portion 312, and when the elastic force of the elastic portion 312 is the elastic force generated by stretching, the electromagnetic induction coil 14 is disposed on the side of the connecting member 31 away from the elastic portion 312.
