The embodiment of the application provides an electronic device, referring to fig. 2a to 2d, fig. 3a and 3b, the electronic device includes: the microphone pickup assembly 1 comprises a housing 2, a display 3 and the microphone pickup assembly 1, wherein the display 3 is arranged on the housing 2, and the microphone pickup assembly 1 is also arranged on the housing 2. The microphone pickup assembly serves as a recording device for video and audio.
The display screen of the electronic device may be a small display screen or a large display screen (for example, 50 inches or more).
In order to reduce the influence on the pickup effect, the appearance attractiveness of the electronic equipment can be improved. The embodiment of the present application provides a microphone pickup assembly 1, referring to fig. 4a and 4b, the microphone pickup assembly 1 includes: the microphone module 12 is provided with a pickup hole 125, the driving structure 13 is relatively fixed with the fixed support 11, the driving structure 13 is connected with the microphone module 12, the driving structure 13 is used for driving the microphone module 12 to move between a lifting position and a falling position along a first direction (such as the P1 direction in fig. 4 b) relative to the fixed support 11, an avoidance hole 201 (such as shown in fig. 3 a) for the microphone module 12 to pass through is formed in the shell 2, the pickup hole 125 is located outside the shell of the electronic device when the microphone module 12 is in the lifting position, the pickup hole 125 is hidden inside the shell of the electronic device when the microphone module 12 is in the falling position (such as shown in fig. 2 b).
When the microphone is required to be started by the video or the microphone is required to be started by the audio, the driving structure can drive the microphone module to move relative to the fixed support, so that the pick-up hole is moved out of the shell to the outside of the shell, and then the pick-up hole is utilized for collecting sound. If the microphone is not needed, the driving structure can drive the microphone module to move relative to the fixed support, so that the pick-up hole exposed outside the shell can be moved to the inside of the shell to be hidden. That is, when the microphone module is not used, the pick-up hole is hidden in the casing, so that the pick-up hole is invisible from the external shape of the electronic device, and the external appearance aesthetic degree of the electronic device can be improved. Compared with the pickup hole which is always exposed outside the shell in the prior art, the influence on the pickup effect is reduced, and the appearance attractiveness of the electronic equipment is improved.
The arrangement position of the microphone pickup assembly 1 in the housing 2 is: referring to fig. 2a, the microphone pickup assembly 1 is arranged in the housing 2 at a position near the top of the housing 1 and near the central area of the housing, and referring to fig. 3a, the avoidance hole 201 is opened at the top of the housing 1. That is, when the pick-up hole is moved out, the pick-up effect is better than setting the pick-up hole at other positions at the top of the housing.
When the microphone pickup assembly is applied to a housing of an electronic device having a large display screen, the arrangement of the pickup holes 125 greatly affects the pickup effect. In order to reduce the influence on the pickup effect, referring to fig. 4a, the pickup holes 125 in the embodiment of the present application are plural, the plural pickup holes 125 are arranged at intervals along the direction perpendicular to the first direction, and the plural pickup holes 125 are symmetrically arranged with respect to the center line O1O2 of the microphone module, the microphone elements in the microphone module are plural, and the plural microphone elements are disposed one-to-one with the plural pickup holes.
The technical effects produced by the design are as follows: referring to fig. 2a, since the plurality of pickup holes 125 are arranged at intervals along the P2 direction perpendicular to the P1 direction and are symmetrically arranged about the center line of the microphone module, the pickup distance (i.e., the distance from the user to the pickup holes) is comparable in fig. 2a regardless of which side of the two sides of the electronic device the user stands on, i.e., whether the user is in the B1 position or the B2 position, so that the pickup effect is almost equal, and it does not occur that the pickup effect is better when the user is in the B1 position than when the user is in the B2 position. In addition, the plurality of pick-up holes 125 are arranged at intervals along the P2 direction perpendicular to the P1 direction, and all the pick-up holes can be exposed or hidden at the same time in the lifting process of the microphone module.
It should be noted that: the symmetrical arrangement of the plurality of pickup holes relative to the center line of the microphone module means that: when the number of the pickup holes is even, the pickup holes with the even number are symmetrically distributed about the central line of the microphone module; when the number of the pick-up holes is odd, one of the pick-up holes is close to the central line of the microphone module, and the rest of pick-up holes are symmetrically distributed relative to the central line of the microphone module.
The plurality of sound pickup holes have a plurality of arrangement modes, and as an example, referring to fig. 2a, the plurality of sound pickup holes 125 are arranged on a straight line parallel to the direction P2; as another example, referring to fig. 2b, the plurality of pickup holes 125 are arranged in a plurality of straight lines, and the pickup holes on each adjacent two straight lines are spaced apart; as another example, referring to fig. 2c, a plurality of sub pickup holes 128 are provided at the periphery of each pickup hole 125, and the sub pickup holes 128 have a smaller aperture than the pickup holes 125, and the plurality of sub pickup holes 128 at the periphery of each pickup hole are annularly arranged.
In order to further improve the appearance aesthetic degree of the electronic equipment, when the microphone module is positioned at the falling position, the top surface of the microphone module is flush with the top surface of the shell.
In order to make the microphone module move along the first direction smoothly under the driving of the driving structure, referring to fig. 4a, the microphone pickup assembly further includes a guiding structure 4, two opposite sides of the microphone module 12 are connected to the fixed support 11 through the guiding structure 4, and the guiding structure 4 is used for guiding the microphone module 12 to slide along the first direction relative to the fixed support 11. I.e. under the guidance of the guiding structure, the microphone module 12 will move smoothly in the first direction.
The structure that can be realized by the guide structure has various cases, and is explained below by means of two embodiments.
Example 1
Referring to fig. 5, 6 and 7, the guide structure 4 includes: the microphone module comprises a guide shaft 14 and a sliding sleeve 15, wherein the guide shaft 14 is relatively fixed with the fixed support 11, the extending direction of the guide shaft 14 is parallel to the first direction, the sliding sleeve 15 is sleeved outside the guide shaft 14, the sliding sleeve 15 can slide along the extending direction of the guide shaft 14, and the microphone module 12 is relatively fixed with the sliding sleeve 15.
When the microphone module 12 is driven by the driving structure to move relative to the fixed support 11, the extending direction of the guiding shaft 14 is parallel to the first direction, so that the sliding sleeve 15 connected with the microphone module 12 slides along the extending direction of the guiding shaft 14, so as to ensure that the microphone module 12 is driven by the driving structure to move stably.
Example two
The guide structure includes: one of the guide rail and the guide groove is arranged on the fixed support, and the other is arranged on the microphone module.
In some embodiments, referring to fig. 8 and 9, the fixed support 11 has lugs 16 at positions near both ends of the guide shaft 14, the lugs 16 have insertion holes, the guide shaft 14 is fixed to the lugs 16 through the insertion holes, and the sliding sleeve 15 is slidably disposed on a shaft section of the guide shaft 14 between the two lugs 16.
