[0002] Smart speakers are the product of speaker upgrades. They are a tool for home consumers to access the Internet using voice, such as ordering songs, shopping online, or getting weather forecasts. They can also control smart home devices, such as opening curtains, setting refrigerator temperature, and heating up water heaters in advance.

[0003] The sound reception of the voice control component is generally performed by opening a sound receiving hole on the shell. However, after long-term use, dust is easily accumulated in the sound receiving hole, which affects the normal sound reception of the voice control component and further affects the use of the voice control component.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 - Figure 3 In the embodiment of the utility model, the voice control component includes a second fixed frame 7 and a dustproof mechanism. A voice control module 9 is arranged inside the second fixed frame 7. A microphone 11 for receiving sound is arranged on the voice control module 9. A through hole 21 is opened on the second fixed frame 7 directly above the microphone 11. The dustproof mechanism is arranged on the second fixed frame 7, and is used to retract the microphone 11 into the second fixed frame 7 when no one is there, and extend the microphone 11 out of the second fixed frame 7 when someone is there.

[0027] The dustproof mechanism includes two connecting plates 8, and the two connecting plates 8 are installed at both ends of the sound control module 9. The lower end of the connecting plate 8 is installed with an electric telescopic rod 6 for pushing the connecting plate 8 to move up and down. The electric telescopic rod 6 is vertically installed at the bottom of the second fixed frame 7. The upper end of the sound tube 11 is installed with a fixed block 12 through a through hole 21. The diameter of the fixed block 12 is larger than the diameter of the sound tube 11. A plurality of infrared sensors 10 for detecting whether there are people are installed in a circular array on the side wall of the fixed block 12. A controller 23 is installed on the inner wall of the second fixed frame 7.

[0028] When in use, the infrared sensor 10 detects in real time whether there are people around. If there are people, the infrared sensor 10 sends a signal to the controller 23, and the controller 23 controls the electric telescopic rod 6 to extend. The output end of the electric telescopic rod 6 pushes the connecting plate 8 to move upward, and the connecting plate 8 drives the voice control module 9 to move upward. The voice control module 9 drives the microphone 11 to move upward, and the microphone 11 passes through the perforation 21 and is exposed, so that the microphone 11 can receive the sound made by the person.

[0029] If no one is there, the infrared sensor 10 will not send a signal to the controller 23. The controller 23 controls the electric telescopic rod 6 to retract. The output end of the electric telescopic rod 6 drives the connecting plate 8 to move downward. The connecting plate 8 drives the voice control module 9 to move downward. The voice control module 9 drives the microphone 11 to move downward. The microphone 11 drives the fixing block 12 to move, so that the fixing block 12 blocks the through hole 21, thereby retracting the microphone 11 into the second fixing frame 7 to protect the microphone 11 from dust.

[0030] See also Figure 1 - Figure 5 The smart speaker using the above-mentioned voice control component includes a speaker body 5, the upper end of the speaker body 5 is installed on the lower end of the second fixed frame 7, the lower end of the speaker body 5 is installed with a first fixed frame 1, the upper end of the side wall of the first fixed frame 1 is installed with a mounting frame 14, the height of the mounting frame 14 is half the height of the speaker body 5, and a retaining ring 13 is slidably connected to the inner wall of the mounting frame 14, the upper end of the retaining ring 13 is tightly attached to the lower end of the second fixed frame 7, and the upper end of the first fixed frame 1 is provided with a driving mechanism for making the speaker body 5 and the retaining ring 13 move up and down in opposite directions.

[0031] The driving mechanism includes two symmetrically arranged motors 17, which are installed at the bottom of the first fixed frame 1. A second rotating rod 3 is vertically installed at the output end of the motor 17. A second screw rod 15 is vertically installed at the upper end of the second rotating rod 3 through the top of the first fixed frame 1. The side wall of the second screw rod 15 is connected to a moving block 16 through threaded rotation. A connecting block 18 is installed at one end of the moving block 16 close to the speaker body 5, and an end of the connecting block 18 away from the moving block 16 is installed at the lower end of the side wall of the speaker body 5.

[0032] The lower end of the retaining ring 13 is provided with two internal thread grooves 22 corresponding to the motor 17 one by one, and the inner wall of the internal thread groove 22 is rotatably connected to the first screw rod 4 through a thread, and the lower end of the first screw rod 4 is installed with a first rotating rod 2, and the lower end of the first rotating rod 2 passes through the top of the first fixed frame 1 and is rotatably connected to the bottom of the first fixed frame 1, and a second gear 20 is installed on the side wall of the first rotating rod 2 inside the first fixed frame 1, and a first gear 19 used in conjunction with the second gear 20 is installed on the side wall of the second rotating rod 3 inside the first fixed frame 1, and the first gear 19 and the second gear 20 are meshed with each other, and the thread directions of the first screw rod 4 and the second screw 15 are the same.

[0033] When the speaker body 5 is started, the control module inside the speaker body 5 controls the motor 17 to start, the motor 17 drives the second rotating rod 3 to rotate, the second rotating rod 3 drives the second screw 15 to rotate, under the action of the thread, the second screw 15 drives the moving block 16 to move upward, the moving block 16 drives the connecting block 18 to move upward, and the connecting block 18 drives the speaker body 5 to move upward.

[0034] At the same time, the second rotating rod 3 drives the first gear 19 to rotate, the first gear 19 drives the second gear 20 to rotate, the second gear 20 drives the first rotating rod 2 to rotate, and the first rotating rod 2 drives the first screw 4 to rotate. Under the action of the thread, the first screw 4 drives the retaining ring 13 to move downward, so that the speaker body 5 is completely moved out of the installation frame 14, which is convenient for the speaker body 5 to play sound.

[0035] When the speaker body 5 is not in use, the control module inside the speaker body 5 controls the motor 17 to start, so that the speaker body 5 moves downward, and the retaining ring 13 moves upward, so that the retaining ring 13 and the mounting frame 14 protect the speaker body 5 from dust.
