Example 1

Referring to fig. 1 to 4, the present embodiment provides an electronic device housing including a housing body 1, an electromagnetic stripe 2, and an electromagnetic grill set 3.

The position on the shell body 1 corresponding to the sound outlet side of the sound outlet component 4 of the electronic device is provided with a sound outlet 11 communicated with the outside, the electromagnetic strip 2 and the electromagnetic grid set 3 are arranged at the sound outlet 11, and the electromagnetic grid set 3 is rotatably connected with the shell body 1, so that when the electromagnetic grid set 3 and the electromagnetic strip 2 are electrified and the electromagnetic grid set 3 and the electromagnetic strip 2 are attracted, the electromagnetic grid set 3 rotates to close the sound outlet 11 relative to the shell body 1, or when the electromagnetic grid set 3 and the electromagnetic strip 2 are electrified and the electromagnetic grid set 3 and the electromagnetic strip 2 are magnetically repelled, the electromagnetic grid set 3 rotates relative to the shell body 1 and at least part of the sound outlet 11 is opened.

In particular, when the electromagnetic grille set 3 is rotatably connected to the shell body 1, and the electromagnetic grille set 3 and the electromagnetic stripe 2 can realize magnetic attraction or repulsion of the electromagnetic grille set 3 and the electromagnetic stripe 2 when being electrified, for example, when currents electrified by the electromagnetic grille set 3 and the electromagnetic stripe 2 are in the same direction, the electromagnetic grille set 3 and the electromagnetic stripe 2 can be magnetic repulsion, and at the moment, the electromagnetic grille set 3 can rotate to be perpendicular to a plane where the sound outlet 11 is located or form a certain included angle relative to the shell body 1 under the action of magnetic mutual exclusion force, and at the moment, the sound outlet 11 is in an open state as shown in fig. 2 so as to facilitate sound. For example, when the current flowing in the electromagnetic grille set 3 and the electromagnetic stripe 2 is different, the electromagnetic grille set 3 and the electromagnetic stripe 2 can attract each other magnetically, the electromagnetic grille set 3 can rotate to be parallel to the plane where the sound outlet 11 is located relative to the shell body 1 under the action of the attraction of the magnetic attraction, and the sound outlet 11 is in a closed state as shown in fig. 3, so that the appearance surface of the whole electronic equipment shell is complete and can be waterproof and dustproof.

In summary, in the electronic equipment housing provided in this embodiment, by arranging the electromagnetic strip 2 and the electromagnetic grating group 3 at the sound outlet 11 of the housing body 1, and enabling the electromagnetic grating group 3 to be rotatably connected to the housing body 1, when audio playing is required, current can be introduced into the electromagnetic strip 2 and the electromagnetic grating group 3 at this time, so that the electromagnetic strip 2 and the electromagnetic grating group 3 are magnetically mutually exclusive, and at this time, the electromagnetic grating group 3 rotates relative to the housing body 1 under the action of the electromagnetic mutual exclusion force to open the sound outlet 11, so that sound playing is convenient; when the audio is not required to be played, current can be introduced into the electromagnetic strip 2 and the electromagnetic grid group 3 at the moment so that the electromagnetic strip 2 and the magnetism of the electromagnetic grid group 3 are attracted, the electromagnetic grid group 3 rotates and rotates relative to the shell body 1 under the action of electromagnetic attraction force to close the sound outlet 11, the appearance surface of the whole shell body 1 is complete so as to avoid affecting the appearance of the whole shell body, and the sound outlet 11 is closed so as to avoid external water or dust and the like from entering the shell body 1 through the sound outlet 11, so that reliable waterproof and dustproof effects are realized.

Referring to fig. 1 to 4, in some embodiments, the electromagnetic grill set 3 includes at least two electromagnetic grills 31, and the electromagnetic strip 2 and the at least two electromagnetic grills 31 are disposed in order along the height direction of the sound outlet 11; when the sound outlet 11 is in a closed state, one of the at least two electromagnetic grids 31 adjacent to the electromagnetic strip 2 is magnetically attracted with the electromagnetic strip 2 and the two adjacent electromagnetic grids 31; when the sound outlet 11 is in the open state, one of the at least two electromagnetic gratings 31 adjacent to the electromagnetic strip 2 and the two adjacent electromagnetic gratings 31 are magnetically repelled.

For example, the electromagnetic grill set 3 includes two electromagnetic grills 31, such as a first electromagnetic grill 31 and a second electromagnetic grill 31, and the electromagnetic strips 2, the first electromagnetic grill 31, and the second electromagnetic grill 31 are sequentially disposed along the top-to-bottom direction of the sound outlet 11. When the sound outlet 11 needs to be opened, magnetism between the electromagnetic strip 2 and the first electromagnetic grid 31 repels, and magnetism between the first electromagnetic grid 31 and the second electromagnetic grid 31 repels, so that the first electromagnetic grid 31 and the second electromagnetic grid 31 can rotate to be perpendicular to the plane where the sound outlet 11 is located or form a certain included angle under the action of corresponding magnetic repulsive force, and the sound outlet 11 is in an opening state shown in fig. 2. When the sound outlet 11 needs to be opened, the magnetism between the electromagnetic strip 2 and the first electromagnetic grid 31 attracts the magnetism between the first electromagnetic grid 31 and the second electromagnetic grid 31, so that the first electromagnetic grid 31 and the second electromagnetic grid 31 can both rotate to be parallel to the plane where the sound outlet 11 is located under the action of the corresponding magnetic attraction force, and the sound outlet 11 is in a closed state as shown in fig. 3.

As shown in fig. 4, for example, the electromagnetic grill set 3 is set to include 6 electromagnetic grills 31, and for convenience of description, the electromagnetic grills 31 of the electromagnetic grill set 3 are numbered sequentially from the top to the bottom of the sound outlet 11, and the numbers of the electromagnetic grills 31 are respectively No. 1, no. 2, no. 3, no. 4, no. 5, and No. 6. When the electronic equipment is in a non-sounding state, namely the sound emitting assembly 4 is in a silent non-working state, the electromagnetic strip 2 is electrified and generates magnetism, the electromagnetic grids 31 of No. 1, no. 2, no. 3, no. 4, no. 5 and No. 6 are electrified and generate magnetism respectively, wherein the magnetic polarities of the top electromagnetic strip 2 are consistent with the magnetic polarities of the electromagnetic grids 31 of No. 2, no. 4 and No. 6 (such as N poles), the magnetic polarities of the electromagnetic grids 31 of No. 1, no. 3 and No. 5 are consistent (such as S poles), so that the magnetic poles of the top electromagnetic strip 2 and the electromagnetic grids 31 of No. 1 to No. 6 form heteropolar cross, and the principle of heteropolar attraction is realized, and the mutual clinging among the electromagnetic grids 31 of the electromagnetic grid group 3 is realized to close the sound emitting port 11.

Similarly, when the audio-frequency playing function of the electronic equipment is started, the current states of the electromagnetic grids 31 of the top electromagnetic strips 2, 4 and 6 are unchanged, the electromagnetic grids 31 of the top electromagnetic strips 2, 3 and 5 are switched into reverse currents, at the moment, the magnetic poles of the electromagnetic grids 31 of the top electromagnetic strips 2, 1 to 6 are identical, the same poles repel each other, and the tightly closed sound outlet 11 is opened rapidly under the action of the electromagnetic.

When the sound stops and the mobile phone needs to be restored to the silent state, the input currents of the No. 1, no. 3 and No. 5 electromagnetic grids 31 are switched again, and at the moment, the complete closing of the sound outlet 11 is completed due to the attraction of the magnetic materials of the No. 1 to No. 6 grids.

For example, when the number of the electromagnetic gratings 31 is 6 as shown in fig. 4, the number of the limiting structures 5 is also 6, and each limiting structure 5 is located on the same side of the corresponding electromagnetic grating 31, for example, as shown in fig. 4, the limiting structures 5 corresponding to each electromagnetic grating 31 are located on the upper side of the corresponding electromagnetic grating 31, so as to ensure that each electromagnetic grating 31 can rotate to a corresponding angle and then achieve synchronous limiting.

Referring to fig. 1 to 4, in some embodiments, the limiting structure 5 includes a limiting protrusion 51 disposed on an inner wall of the case body 1 and protruding along a direction away from the sound outlet 11, and limiting of the electromagnetic grill 31 is achieved through the limiting protrusion 51, which is reliable in limiting effect, simple in structure, and low in cost.
