[0027] Reference Figure 1 , Figure 1 The structural schematic diagram of an electronic device of some embodiments of the present application.

[0028] In a first aspect, as Figure 1 shown, the embodiments of the present application provide an electronic device 100, the electronic device 100 comprising an audio assembly 200 and a housing 300, the audio assembly 200 being arranged in the housing 300, the housing 300 comprising a first surface 310 arranged towards the audio assembly 200, the first surface 310 being provided with a flow guide groove 330, the flow guide groove 330 being used to deflect at least part of the airflow entering the chamber of the flow guide groove 330.

[0029] The audio assembly 200 of the electronic device 100 works to cause air in the inner cavity thereof to oscillate, and the airflow of the oscillation can impact the shell 300 of the electronic device 100 to cause vibration of the shell 300. The impact force of the airflow on the shell 300 can be decomposed into a force perpendicular to the first surface 310 and a force parallel to the first surface 310. Since the shell 300 is provided with connecting mechanisms such as bolts and rivets on the circumferential side thereof, the vibration amplitude of the shell 300 caused by the impact force parallel to the first surface 310 is small, and the vibration of the shell 300 is mainly caused by the impact force perpendicular to the first surface 310. For example, the audio assembly 200 can be a loudspeaker module or a receiver module.

[0030] Optionally, the flow guide groove 330 is recessed from the first surface 310, or a plurality of flow guide blocks (not shown in the figure) are protrudingly arranged on the first surface 310, and the flow guide groove 330 is arranged between two adjacent flow guide blocks and is enclosed by the first surface 310 and the two opposite side walls of the two adjacent flow guide blocks. The flow guide block is fixedly connected to the first surface 310, or the flow guide block is detachably arranged on the first surface 310.

[0031] The electronic device 100 provided by the embodiment of the present application comprises an audio assembly 200 and a shell 300, the audio assembly 200 is arranged in the shell 300, and the shell 300 is provided with a flow guide groove 330 on the first surface 310 facing the audio assembly 200. When the audio assembly 200 works, the vibration of the air in the shell 300 is caused, and the deflection of the vibrating air occurs after the vibrating air enters the flow guide groove 330, so as to reduce the impact force of the airflow on the shell 300 and improve the problem of vibration of the shell 300 caused by the impact of the airflow.

[0032] Therefore, by arranging the flow guide groove 330 on the first surface 310 of the shell 300, when the airflow in the shell 300 oscillates due to the work of the audio assembly 200, the flow guide groove 330 can deflect the airflow entering the flow guide groove 330, so as to reduce the impact force of the airflow on the shell 300, and improve the problem of poor user experience caused by the vibration of the shell 300.

[0033] Referring to Figure 2 and Figure 3 , Figure 2 the structural schematic view of the shell of the electronic device of some embodiments of the present application; Figure 3 the schematic view of the flow guide groove of the electronic device of some embodiments of the present application.

[0035] The extending direction of the first side wall 334 intersects the thickness direction of the shell 300, and the slot opening area is greater than the slot bottom area. The first side wall 334 is a side wall 331 arranged at least partially inclined in the flow guide groove 330.

The first side wall 334 is arranged inclined. Illustratively, the airflow impacts on the action point of the first side wall 334, and force decomposition occurs at the action point, the impact force of the airflow is decomposed into a vertical force perpendicular to the surface of the first side wall 334 and a parallel force parallel to the surface of the first side wall 334, wherein the vertical force causes the shell 300 to vibrate at the action point, but the parallel force does not cause the shell 300 to vibrate at the action point, and the vertical force is less than the original airflow impact force, which achieves the purpose of reducing the vibration of the shell 300.

[0037] Part of the parallel force will impact the shell 300 in the length or width direction of the shell 300, but the device shell 300 is fixed by screws, buckles and the like, so this part of the parallel force will not cause the shell 300 to vibrate significantly.

[0038] Optionally, the flow guide groove 330 is a tapered groove provided only with the side wall 331, and in the case of a fixed slot opening area, the tapered groove can be provided with a larger area of the side wall 331, that is, the first side wall 334 in the tapered groove can be provided with a larger area to improve the flow guiding capacity of the flow guide groove 330.

The first sidewall 334 arranged in an inclined manner can deflect at least part of the airflow impacting the shell 300, decompose part of the impact force of the airflow acting on the shell 300, reduce the impact force of the airflow on the shell 300, and improve the problem of poor user experience caused by the vibration of the shell 300 due to the impact of the airflow.

[0044] Referring to Figure 2 and Figure 4 , Figure 4 FIG. 1 is a structural schematic diagram of a shell of an electronic device according to some embodiments of the present application.

[0045] In some embodiments, as shown in Figure 2 and Figure 4 , at least two flow guide grooves 330 are arranged in a spaced manner along the width direction of the shell 300; and / or, at least two flow guide grooves 330 are arranged in a spaced manner along the length direction of the shell 300.

The shell 300 is provided with a plurality of flow guide grooves 330 to improve the shock absorption effect of the flow guide grooves 330. The plurality of flow guide grooves 330 are arranged along the length and width directions of the shell 300, which reduces the processing difficulty of the flow guide grooves 330 and improves the preparation efficiency of the flow guide grooves 330.

[0050] In some embodiments, as shown in Figure 2 and Figure 3 , at least part of the first sidewall 334 is a curved surface curved towards the inside of the flow guide groove 330.

[0051] The first sidewall 334 arranged in a curved manner can be decomposed into an infinite number of micro-planes with different slopes. The airflow impacting the action point will be deflected to the length or width direction of the shell 300 by the infinite number of micro-planes.

[0053] Optionally, the angle between the curved surface and the bottom wall of the flow guide groove 330 is 180°, so that the curved surface can deflect part of the airflow to be parallel to the length or width direction of the shell 300.

[0054] In these embodiments, the first side wall 334 is a curved surface, which can deflect the airflow more smoothly than a flat surface when the airflow hits the first side wall 334, thereby improving the deflection effect of the airflow in the flow guide groove 330 and improving the shock absorption effect of the flow guide groove 330.

[0055] Referring to Figure 4 and Figure 5 , Figure 5 Fig. 1 is a structural schematic diagram of a flow guide groove of an electronic device according to some embodiments of the present application.

[0057] The airflow impact force is decomposed into a first vertical force and a first parallel force on the first side wall 334, the first vertical force causes the shell 300 to vibrate, and the first parallel force is deflected in the flow guide groove 330 and hits the second side wall 335 along the length or width direction of the shell 300, and is decomposed under the action of the second side wall 335, decomposing a second vertical force perpendicular to the second side wall 335 and opposite to the direction of the first vertical force, the second vertical force and the first vertical force partially offset, further reducing the vibration degree of the shell.

[0058] Optionally, the first side wall 334 and the second side wall 335 are both inclined planes, or at least one of the first side wall 334 and the second side wall 335 is a curved surface.

[0059] In these embodiments, the flow guide groove 330 includes a second side wall 335 opposite the first side wall 334, when the airflow is deflected by the first side wall 334 to the second side wall 335, the second side wall 335 continues to deflect the airflow to offset part of the vibration caused by the airflow hitting the first side wall 334, thereby reducing the vibration degree of the shell 300 and improving the user experience.

[0060] In some embodiments, as shown in Figure 3 to Figure 5As shown, the flow guide groove 330 further comprises oppositely arranged inlet end and outlet end, the first side wall 334 is arranged close to the inlet end, and the second side wall 335 is arranged close to the outlet end.

The inlets of the two loop grooves 352 are in communication with the first groove 340, and the outlets of the two loop grooves 352 are oppositely arranged.

[0066] After being deflected by the first side wall 334 of the flow guide groove 330, the airflow flowing along the width or length direction of the shell 300 still has a large flow rate and impact force. This part of airflow may impact other components in the shell 300 to cause the connection of other components to be loose, or this part of airflow may still impact the first surface 310 after being deflected by colliding between other components, thereby causing vibration. Therefore, it is necessary to reduce the impact force of this part of airflow.

The multiple ring groove groups 351 arranged at intervals make the cancellation efficiency of the airflow higher, further improve the ability of the flow guide groove 330 to relieve the vibration of the shell 300, and improve the user experience.

[0075] Considering that the airflow cannot be uniformly distributed in the two loop grooves 352 and the airflow in the loop grooves 352 interferes with each other, the airflow cannot be completely canceled at the outlet end of the ring groove group 351, at this time, part of the airflow will enter the third groove 360 arranged in communication with the second groove 350, the third groove 360 has an inclined third side wall 336, the airflow impacts the third side wall 336, and force decomposition occurs on the third side wall 336 to cancel part of the impact force of the airflow acting on the first side wall 334.
