Detailed Implementation

[0067] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention. The technical solutions of this invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0068] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. The intelligent audio device and automatic lifting control method of the sound column according to the present invention are described below with reference to Figures 1 to 39.

[0069] According to a first aspect embodiment of the present invention, the intelligent audio device includes a speaker assembly 100, a housing 200, and a drive assembly 300; the housing 200 is provided with at least one first receiving position 210; one end of the first receiving position 210 extends to the outer wall of the housing 200 to form a first opening 220; the first receiving position 210 is used to receive the speaker assembly 100; the drive assembly 300 is connected to the speaker assembly 100 and is capable of driving the speaker assembly 100 to reciprocate between a first position and a second position; wherein, when the speaker assembly 100 is in the first position, the speaker assembly 100 is located within the first receiving position 210; when the speaker assembly 100 is in the second position, the speaker assembly 100 is at least partially located outside the first receiving position 210.

[0070] The sound column assembly 100 is located within the first receiving position 210. The housing 200 can accommodate the sound column assembly 100 through the first receiving position 210. When the sound column assembly 100 needs to be used, the drive assembly 300 can drive the sound column assembly 100 to move from the first position to the second position. When the sound column assembly 100 is in the second position, it is at least partially located outside the first receiving position 210, allowing it to be used normally. The drive assembly 300 can also drive the sound column assembly 100 to move from the second position to the first position, so that when the sound column assembly 100 is in the first position, it can... The device moves into the first receiving position 210 to accommodate the speaker column assembly 100. Compared to plug-in speaker column and speaker box structures, the intelligent audio device of the present invention can drive the speaker column assembly 100 to move and reciprocate between the first and second positions via the drive component 300. This makes it more convenient to use, provides better stability, and can intelligently switch the sound field and adjust the degree of freedom. Furthermore, since the intelligent audio device of the present invention is connected to the speaker column assembly 100 via the drive component 300, there is no need to assemble the speaker column assembly 110. It is ready to use immediately, which greatly enhances its ease of use and reduces transportation costs, as it does not require separate packaging for transportation.

[0071] Specifically, referring to Figures 3 and 4, the first receiving position 210 can be a cavity structure formed by five or fewer sides, wherein the first receiving position 210 can be a cavity structure formed by four sides; of course, the first receiving position 210 can also be a groove structure. It should be emphasized that after the sound column assembly 100 is stored, the sound output direction of the sound column assembly 100 before and after storage remains unchanged, and the sound column assembly 100 is completely stored inside the outer shell 200, so the stored sound column assembly 100 cannot be seen from the outside of the outer shell 200.

[0072] Specifically, referring to Figure 2, the first position is the horizontal position of the first opening 220, and the second opening is the position at a preset height from the horizontal position of the first opening 220 or the bottom surface of the speaker; taking the horizontal position of the first opening 220 as an example, the height position can be 75cm to 120cm.

[0073] Specifically, the top surface of the sound column assembly 100 is used as the criterion for determination. When the sound column assembly 100 is in the first position, the top surface of the sound column assembly 100 is in the first position or below. When the sound column assembly 100 is in the second position, the distance between the top surface of the sound column assembly 100 in the second position and the first position is the preset distance.

[0074] Specifically, the drive component 300 drives the sound column assembly 100 to move, such that the sound column assembly 100 is at least partially located outside the first receiving position 210. The drive component 300 can drive the sound column assembly 100 to move vertically to be located outside the first receiving position 210, or horizontally to be located outside the first receiving position 210. Of course, it can move in any direction to be located outside the first receiving position 210.

[0075] Specifically, the first opening 220 can be an open structure that is never closed, so that the sound column assembly 100 can easily extend into and out of the first opening 220. After the sound column assembly 100 is stored in the first receiving position 210, the top of the sound column assembly 100 can close the first opening 220 to prevent external materials from falling into the first receiving position 210 from the first opening 220. Of course, depending on the specific situation, a selective closing structure can be provided at the first opening 220. The selective closing structure can close the first opening 220 as needed. The closing structure can be composed of a cover plate and a rotating shaft. The rotating shaft is connected to the housing 200, and the cover plate can be rotatably connected to the rotating shaft. Rotating the cover plate can make the cover plate rotate to close the first opening 220. When the sound column assembly 100 extends out of the first opening 220, the cover plate can be pushed open. By setting the cover plate, the first opening 220 can be closed, thereby improving the protection capability.

[0076] Referring to Figures 1 and 2, it can be understood that the sound column assembly 100 includes a sound column body 120 and a sound column housing 110, with the sound column body 120 connected to the sound column housing 110; the drive assembly 300 is drivenly connected to the sound column housing 110 and / or the sound column body 120, and drives the sound column body 120 and the sound column housing 110 to move.

[0077] The drive assembly 300 is driven to move the sound column housing 110, so that when the drive assembly 300 moves the sound column housing 110, the sound column housing 110 can drive the sound column body 120 to move, so that the sound column body 120 and the sound column housing 110 move together and reciprocate between the first position and the second position.

[0078] Specifically, the sound column housing 110 is disposed outside the sound column body 120 so as to protect the sound column body 120, and the sound-producing unit of the sound column assembly 100 can be disposed inside the sound column body 120.

[0079] The effectiveness of the rear cavity's sealing significantly impacts the low-frequency response of sound, which greatly affects sound quality. The further left the low-frequency peak is, the more prominent the bass becomes, subjectively resulting in a more pleasing sound. Generally, as the rear cavity volume increases, the low-frequency peak of its frequency response curve shifts further to the left, improving low-frequency characteristics. However, when leakage occurs in the rear cavity, low frequencies attenuate, damaging sound quality. The degree of impact from leakage is related to the leakage area and location. Generally, the larger the leakage area, the more severe the low-frequency attenuation. The leakage area and the attenuation of the low-frequency resonant point are approximately linearly related. For the same leakage area, a smaller rear cavity results in greater low-frequency attenuation, meaning the damage caused by leakage is greater.

[0080] Referring to Figures 8 and 9, depending on the specific circumstances, the drive assembly 300 can be driven and connected to the sound column housing 110 and the sound column body 120. Specifically, the drive assembly 300 is built into the sound column body 120 and extends out of the sound column body 120 to connect to the sound column housing 110. The drive assembly 300 first pushes the sound column body 120 to rise, and then drives the housing 110 to rise; the drive assembly 300 can first push the housing 110 to fall, and then drive the sound column body 120 to fall.

[0081] Referring to Figures 8 and 9, the drive assembly 300 can be equipped with multiple motors to cooperate with multiple screws, thereby driving the sound column housing 110 and the sound column body 120 to move up and down respectively. This allows the drive assembly 300 to drive the sound column body 120 to extend from the first opening 220 to the outside of the first receiving position 210, while the sound column housing 110 remains inside the first receiving position 210. Alternatively, the drive assembly 300 can also drive the sound column housing 110 to extend from the first opening 220 to the outside of the first receiving position 210, while the sound column body 120 remains inside the sound column housing 110.

[0082] Depending on the specific circumstances, the drive assembly 300 can be driven to connect with the sound column body 120; the sound column body 120 and the sound column housing 110 abut against each other. After the drive assembly 300 drives the sound column body 120 to rise, it can also drive the sound column housing 110 to rise together until the bottom of the sound column housing 110 rises to the first opening. The outer shell 100 limits the rising position of the sound column housing 110, and the sound column body 120 continues to rise to its predetermined position. After the drive assembly 300 drives the sound column body 120 to fall, it can also drive the sound column housing 110 to fall together until the sound column housing 110 falls to its predetermined position. The outer shell 100 limits the falling position of the sound column housing 110, and the sound column body 120 continues to fall to its predetermined position, until it is located in the first receiving position 210.

[0083] Referring to Figures 26 and 29, specifically, a sliding block 101 can be provided inside the sound column housing 110, and a sliding groove 102 can be provided outside the sound column body 120. The sliding block 101 is slidably disposed in the sliding groove 102, which can limit the stability of the relative sliding between the sound column housing 110 and the sound column body 120. The sliding block 101 can be a rack, which makes the sound column body 120 and the sound column housing 110 fit tightly, thereby reducing the gap between the two.

[0084] Referring to Figures 23, 24, and 25, specifically, the drive assembly 300 can drive the sound column body 120 and the sound column housing 110 to move, so that a portion of the sound column housing 110 can move from the first opening 220 to outside the first receiving position 210, and a portion of the sound column body 120 can move to outside the sound column housing 110, so that the sound column assembly 100 can move to a position between the first position and the second position.

[0085] Referring to Figures 1 and 2, it can be understood that the sound column housing 110 is disposed through and sleeved outside the sound column body 120; the sound column body 120 is slidably connected to the sound column housing 110 and can slide relative to the sound column housing 110 in a first direction; the drive assembly 300 is connected to the sound column body 120 and the sound column housing 110, and the drive assembly 300 can drive the sound column housing 110 to move at least partially from the first opening 220 to outside the first receiving position 210, and can drive the sound column body 120 to move at least partially outside the sound column housing 110.

[0086] The sound column housing 110 is sleeved on the sound column body 120 to protect the sound column body 120. The sound column housing 110 is disposed through a first direction, and the sound column body 120 slides back and forth in the first direction within the sound column housing 110. By providing the driving component 300, the sound column housing 110 can be driven to extend from the first opening 220 to the outside of the first receiving position 210, so that the sound column assembly 100 extends from the first opening 220. Furthermore, the driving component 300 can drive the sound column body 120 to extend from inside the sound column housing 110 to outside the sound column housing 110, so that the sound column body 120 can perform sound production normally, preventing the sound column housing 110 from blocking the sound emitted by the sound column body 120 and ensuring the sound quality of the sound column body 120.

[0087] Specifically, the sound column housing 110 is provided to form a first through-hole and a second through-hole, the first through-hole and the second through-hole are arranged opposite to each other, and the sound column body 120 can slide relative to the sound column housing 110 through the first through-hole and the second through-hole.

[0088] Referring to Figures 4, 5, 10, 11 and 12, it can be understood that the drive assembly 300 includes a drive member 301 and a first screw 310; the first screw 310 is threadedly connected to the sound column housing 110; the drive member 301 is drivenly connected to the first screw 310 and is capable of driving the first screw 310 to rotate around a first direction.

[0089] Since the first screw 310 is threadedly connected to the sound column housing 110, when the driving member 301 drives the first screw 310 to rotate around the first direction, it can drive the sound column housing 110 to move along the first direction, thereby enabling the sound column housing 110 to extend from the first opening 220 or retract into the first receiving position 210.

[0090] Specifically, the shape of the first opening 220 is non-circular, and the cross-section of the sound column housing 110 is also non-circular. The outer wall of the sound column housing 110 abuts against the inner wall of the first opening 220 to prevent the sound column housing 110 from rotating within the first receiving position 210.

[0091] Specifically, the cross-section of the first receiving position 210 is non-circular, and the cross-section of the sound column housing 110 is also non-circular. The outer wall of the sound column housing 110 abuts against the inner wall of the first receiving position 210 to prevent the sound column housing 110 from rotating within the first receiving position 210.

[0092] Specifically, after the drive assembly 300 drives the sound column housing 110 to rise, it can also drive the sound column body 120 to rise together. The bottom of the sound column body 120 can be raised or lowered to the first opening 220, so as to reduce the height of the sound column assembly 100 and adapt to the surrounding environment.

[0093] Referring to Figures 4, 5, 10, 11 and 12, it can be understood that the drive assembly 300 also includes a second screw 320; the drive member 301 is drivenly connected to the second screw 320 and is capable of driving the second screw 320 to rotate; the second screw 320 is threadedly connected to the sound column body 120.

[0094] Since the second screw 320 is threadedly connected to the sound column body 120, when the driving member 301 drives the second screw 320 to rotate around the first direction, it can drive the sound column body 120 to move along the first direction, thereby enabling the sound column body 120 to extend from inside the sound column housing 110 or retract into the sound column housing 110.

[0095] Specifically, the cross-section of the sound column housing 110 is non-circular, and the cross-section of the sound column body 120 is also non-circular. The outer wall of the sound column body 120 abuts against the inner wall of the sound column housing 110 to prevent the sound column body 120 from rotating inside the sound column housing 110.

[0096] Specifically, the drive unit 301 can drive a rotary motor.

[0097] Referring to Figures 4, 5, 17, 18, and 19, it can be understood that the second screw 320 is rotatably connected to the sound column housing 110; the second screw 320 is through-hole disposed, and the second screw 320 is slidably sleeved on the first screw 310; a sliding groove 302 is provided on the first screw 310, and a slider 303 is provided on the second screw 320, and / or, the sliding groove 302 is provided on the second screw 320, and the slider 303 is provided on the first screw 310; the slider 303 is slidably disposed within the sliding groove 302; the extending direction of the sliding groove 302 is in the same direction as the axial direction of the first screw 310.

[0098] The second screw 320 is disposed through and sleeved outside the first screw 310. One of the first screw 310 and the second screw 320 is provided with a groove 302, and the other is provided with a slider 303. The slider 303 is slidably disposed in the groove 302, so that the first screw 310 and the second screw 320 can rotate synchronously. The driving member 301 drives the first screw 310 to rotate, which can drive the second screw 320 to rotate. The first screw 310 and the second screw 320 can slide relative to each other in a first direction.

[0099] Of course, depending on the specific circumstances, at least one groove 302 and one slider 303 are provided on the first screw 310 and the second screw 320 respectively. The groove of the first screw 310 cooperates with the slider of the first screw 310, and the slider of the first screw 310 cooperates with the groove of the first screw 310, so as to further improve the stability of the relative sliding of the first screw 310 and the second screw 320.

[0100] Referring to Figures 2, 5, and 12, specifically, the driving member 301 drives the first screw 310 to rotate, enabling the sound column housing 110 to move along the first direction. Since the second screw 320 is rotatably connected to the sound column housing 110, the sound column housing 110 can drive the second screw 320 to move along the first direction. When the driving member 301 drives the first screw 310 to rotate, it can drive the second screw 320 to rotate, causing the sound column body 120 to also move along the first direction. Therefore, when the driving member 301 drives the first screw 310 to rotate, the sound column housing 110 can move relative to the outer shell 200 along the first direction, allowing the sound column housing 110 to extend from the first opening 220, and the sound column body 120 can move relative to the sound column housing 110 along the first direction, allowing the sound column body 120 to extend from inside the sound column housing 110 to outside the sound column housing 110.

[0101] Referring to Figures 8 and 9, specifically, when the sound column housing 110 extends from the first opening 220 and the sound column body 120 extends from inside the sound column housing 110 to outside the sound column housing 110, both the sound column housing 110 and the sound column body 120 are located outside the first receiving position 210, and the sound column assembly 100 achieves two-stage lifting and lowering, at which time the sound column assembly 100 is in the second position.

[0102] Referring to Figure 6, specifically, when the sound column housing 110 extends from the first opening 220 into the first receiving position 210, and the sound column body 120 extends into the outside of the sound column housing 110, both the sound column housing 110 and the sound column body 120 are located within the first receiving position 210, and the sound column assembly 100 achieves two-stage lifting and lowering, at which time the sound column assembly 100 is in the first position.

[0103] Referring to Figures 17, 18, and 19, specifically, a slider 303 is provided on the inner wall of the first screw 310, and a groove 302 is provided on the outer wall of the second screw 320. The slider 303 is slidably disposed in the groove 302. The groove 302 is through-hole disposed so that the second screw 320 can pass into the first screw 310.

[0104] Of course, depending on the specific circumstances, a groove 302 is provided on the inner wall of the first screw 310, and a slider 303 is provided on the outer wall of the second screw 320; in other cases, a slider 303 and a groove 302 are provided on the inner wall of the first screw 310, and a slider 303 and a groove 302 are also provided on the outer wall of the second screw 320. The slider 303 on the inner wall of the first screw 310 is slidably disposed within the groove 302 on the outer wall of the second screw 320, and the groove 302 on the inner wall of the first screw 310 is slidably disposed within the slider 303 on the outer wall of the second screw 320, so as to improve the stability of the connection.

[0105] Referring to Figure 17, multiple sliders 303 can be provided, and multiple sliding grooves 302 are correspondingly provided. Multiple sliders 303 are slidably disposed in multiple sliding grooves 302, so as to further improve the stability of the connection, improve the stability of the relative sliding of the first screw 310 and the second screw 320, and improve the stability of the synchronous rotation of the first screw 310 and the second screw 320.

[0106] Since the height of the sound column assembly 100 can also be relatively high within the first receiving position 210, which is relatively high, the sound column assembly 100 can also be raised relatively high. Referring to Figures 30 to 35, it can be understood that the drive assembly 300 includes a third screw and a drive member 301, and the drive member 301 is drivenly connected to the third screw. The sound column assembly 100 includes a sound column body 120 and a sound column housing 110, the sound column body 120 is connected to the sound column housing 110, the third screw is threadedly connected to the sound column housing 110 and / or the sound column body 120, and the drive member 301 drives the third screw to rotate, thereby driving the sound column housing 110 and the sound column body 120 to reciprocate. Alternatively, the sound column assembly 100 includes a sound column body 120, the third screw is threadedly connected to the sound column body 120, and the drive member 301 drives the third screw to rotate, thereby driving the sound column body 120 to reciprocate.

[0107] Referring to Figures 30 and 31, specifically, the sound column body 120 is connected to the sound column housing 110. The third screw can pass through the sound column body 120 and the sound column housing 110 and is threadedly connected to the sound column body 120. The driving member 301 drives the third screw to rotate, so as to drive the sound column body 120 and the sound column housing 110 to reciprocate simultaneously. After the sound column body 110 moves, the sound column housing 120 also moves synchronously, so as to expand the acoustic volume of the sound column assembly 100.

[0108] Referring to Figures 32 and 33, specifically, the sound column body 120 is connected to the sound column housing 110, and the third screw can pass through the sound column housing 110 and be threadedly connected to the sound column body 110. The driving member 301 drives the third screw to rotate, thereby driving the sound column body 110 to reciprocate, thereby driving the sound column body 120 to reciprocate. By setting the sound column housing 110, the sound column body 120 can be protected, and the airtightness of the rear cavity space can be improved.

[0109] Referring to Figures 34 and 35, specifically, the third screw can pass through the sound column body 120 and be threadedly connected to the sound column body 120. The driving member 301 drives the third screw to rotate, so as to drive the sound column body 120 and the sound column housing 110 to reciprocate simultaneously. Based on this, the sound column housing 110 is eliminated to simplify the structure of the sound column assembly 100 and reduce the weight of the sound column assembly 100.

[0110] Referring to Figures 5 and 12, it can be understood that the sound column housing 110 includes a first main body 111 and a first lifting nut 112; the first lifting nut 112 is fixedly connected to the first main body 111 and threadedly connected to the first screw 310; the sound column body 120 includes a second main body 121 and a second lifting nut 122; the second lifting nut 122 is fixedly connected to the second main body 121 and threadedly connected to the second screw 320.

[0111] The first lifting nut 112 is fixedly connected to the first body 111 to prevent the first lifting nut 112 from rotating synchronously with the first screw 310, thereby improving the stability of the transmission; the second lifting nut 122 is fixedly connected to the second body 121 to prevent the first lifting nut 112 from rotating synchronously with the first screw 310, thereby improving the stability of the transmission.

[0112] Specifically, the first lifting nut 112 can be located on the outside of the first body 111 to prevent the first screw 310 from affecting the sound-generating element inside the first body 111. Alternatively, the first lifting nut 112 can be located inside the first body 111 to save space occupied by the sound column assembly 100. The second lifting nut 122 can be located on the outside of the second body 121 to prevent the second screw 320 from affecting the sound-generating element inside the second body 121. Alternatively, the second lifting nut 122 can be located inside the second body 121 to save space occupied by the sound column assembly 100.

[0113] Referring to Figures 11, 12, 27, and 28, it can be understood that the first main body 111 is provided with a first through-hole 113, and the second main body 121 is provided with a second through-hole 123; the first through-hole 113 and the second through-hole 123 are arranged opposite to each other; the first lifting nut 112 is provided at the first through-hole 113; the second lifting nut 122 is provided at the second through-hole 123; the first screw 310 passes through the first through-hole 113, and the first screw 310 is at least partially located inside the first main body 111; the second screw 320 passes through the second through-hole 123, and the second screw 320 is at least partially located inside the second main body 121.

[0114] The first opening 113 and the second opening 123 are arranged opposite to each other in a first direction. The first lifting nut 112 is located at the first opening 113; the second lifting nut 122 is located at the second opening 123, such that the first screw 310 passes through the first opening 113 and the second opening 123 in sequence. The first screw 310 is at least partially located inside the sound column body 120 and the sound column housing 110, so as to reduce the space occupied by the first screw 310 and limit the direction of movement of the sound column body 120 and the sound column housing 110. The second screw 320 is sleeved outside the first screw 310, passes through the second opening, and is at least partially located inside the sound column body 120, so as to reduce the space occupied by the second screw 320 and limit the direction of movement of the sound column body 120 and the sound column housing 110.

[0115] Specifically, the first screw 310 and the second screw 320 are arranged in the same direction; the second screw 320 is located inside the sound column housing 110 so that the sound column housing 110 can protect the second screw 320.

[0116] Referring to Figures 5 and 11, it can be understood that the sound column housing 110 includes a first body 111, a connector 114, and a limiting member 116. The connector 114 is connected to the second screw 320, and the limiting member 116 is connected to the first body 111, and a placement cavity 117 is defined between the connector 114 and the first body 111. The connector 114 is rotatably disposed in the placement cavity 117.

[0117] A placement cavity 117 is formed between the limiting member 116 and the first body 111. The position of the connector 114 can be limited by the placement cavity 117. Since the connector 114 is connected to the second screw 320, the position of the second screw 320 can be limited. When the second screw 320 rotates under the drive of the first screw 310, the connector 114 can also rotate within the placement cavity 117.

[0118] When the sound column housing 110 moves along the first direction, the connector 114 can abut against the inner wall of the placement cavity 117 along the first direction, so that the inner wall of the placement cavity 117 can abut against the connector 114, thereby pushing the second screw 320 to move relative to the first screw 310. Thus, when the sound column housing 110 moves, it drives the second screw 320 to move. And since the second screw 320 is threadedly connected to the sound column body 120, the second screw 320 can drive the sound column body 120 to move along the first direction. There can be a gap between the connector 114 and the inner wall of the placement cavity 117. The connector 114 and the inner wall of the placement cavity 117 can abut directly or indirectly. Among them, a filler can be placed in the gap between the connector 114 and the inner wall of the placement cavity 117 to achieve indirect abutment.

[0119] Specifically, the driving member 301 drives the first screw 310 to rotate, which enables the sound column housing 110 to move along the first direction. The inner wall of the placement cavity 117 formed by the first main body 111 of the sound column housing 110 and the limiting member 116 abuts against the connecting member 114, so as to drive the second screw 320 connected to the connecting member 114 to move along the first direction and drive the sound column body 120 to move, so that the sound column housing 110 and the sound column body 120 simultaneously extend from the first opening 220 to the outside of the first receiving position 210. Since the driving member 301 drives the first screw 310 to rotate, it can drive the second screw 320 to rotate and enable the sound column body 120 to move relative to the sound column housing 110 along the first direction, so that the sound column body 120 extends from inside the sound column housing 110 to outside the sound column housing 110.

[0120] Specifically, the second main body 121 includes a shell body 118 and a base 119. The shell body 118 is through-hole disposed, and the sound column body is movable through the shell body 118 in a first direction. The base 119 is disposed at one end of the shell body 118, and the first opening 113 is disposed on the base 119.

[0121] Referring to Figures 3 and 4, it can be understood that the outer casing 200 is also provided with a second receiving position 230; the second receiving position 230 is connected to the first receiving position 210, or the second receiving position 230 is separated from the first receiving position 210.

[0122] The second receiving position 230 is used for electronic components, such as microphones.

[0123] The second receiving position 230 can be separated from the first receiving position 210 to prevent the electronic components in the second receiving position 230 from affecting the sound column assembly 100.

[0124] Of course, depending on the specific circumstances, the second accommodating position 230 can be connected to the first accommodating position 210, and the driving component 300 can be placed in the second accommodating position 230 to reduce the space occupied in the first accommodating position 210.

[0125] Referring to Figure 10, it can be understood that the second receiving position 230 is connected to the first receiving position 210; one end of the sound column housing 110 is connected to the sound column body 120; when the sound column body 120 is in the second position, the end of the sound column housing 110 away from the sound column body 120 is located between the sound column body 120 and the outer shell 200.

[0126] After the speaker column assembly 100 is raised, the speaker column body 120 is located in the second position and outside the first receiving position 210. A rear cavity space is defined between the outer shell 200 and the end of the speaker column housing 110 away from the speaker column body 120. The outer shell 200 also seals the bottom of the speaker column assembly 100. This ensures the stability of the air pressure inside the outer shell 200 and expands the volume of the rear cavity space. A low-frequency speaker is also installed in the first receiving position 210. Keeping the outer shell 200 sealed can prevent low-frequency attenuation, and the expansion of the rear cavity space can make the low-frequency peak more pronounced. The leftward shift makes the bass more prominent, improving sound quality. Furthermore, to ensure the airtightness of the rear cavity, fillers such as EVA and silicone can be placed between the outer shell 200 and the speaker column housing 110, and between the speaker column housing 110 and the speaker column body 120, to improve the airtightness of the rear cavity and reduce the degree of leakage. The second receiving position 230 is connected to the first receiving position 210, so that both the second receiving position 230 and the first receiving position 210 can serve as the rear cavity space, thereby further increasing the volume of the rear cavity space.

[0127] Specifically, after the drive assembly 200 drives the sound column housing 110 to move upward, the rear cavity space can be defined between the outer shell 200 and the end of the sound column housing 110 away from the sound column body 120; of course, the rear cavity space can also exist on its own without the drive assembly 200 driving the sound column housing 110 to move upward.

[0128] Referring to Figure 3, specifically, the outer shell 200 is composed of a first shell 201 and a second shell 202, wherein a first receiving position 210 is disposed in the first shell 201, a first opening 220 is disposed on the first shell 201, and a second receiving position 230 is disposed in the second shell 202.

[0129] Of course, depending on the specific circumstances, the first receiving position 210 is located inside the first housing 201, the first opening 220 is located on the first housing 201, and the first housing 201 and the second housing 202 together define the second receiving position 230.

[0130] Specifically, the speaker assembly 40 of the first cavity can be one or more of the following: a low-frequency speaker, a low-frequency speaker and a high-frequency speaker, a low-frequency speaker and a full-range speaker, or a low-frequency speaker, a high-frequency speaker and a full-range speaker.

[0131] Understandably, it also includes a screen assembly, which includes a screen that is movably connected to the housing 200 to improve the ease of use of the screen, and by setting up the screen, the functionality of the smart audio device can be improved.

[0132] The screen 10 is mounted outside the housing 200 via a hinge structure, or it can be mounted outside the top housing 60 or the bottom housing 70.

[0133] Referring to Figure 2, specifically, the microphone, microphone housing structure, low-frequency speaker, and screen assembly can be arranged on the same side of the housing 200, while the speaker column assembly 100 is arranged on the other side, so as to balance the mass on the housing 200 and reduce the possibility of the smart audio device tipping over after the speaker column assembly 100 is raised; wherein, the microphone, microphone housing structure, low-frequency speaker, and screen assembly can all be arranged on the front side of the housing 200, while the speaker column assembly 100 is arranged on the rear side.

[0134] Referring to Figures 1, 15 and 16, it can be understood that the casing is provided with a storage compartment 240 for storing the screen.

[0135] The screen can be moved into the storage compartment 240, which can accommodate the screen; the storage compartment 240 is located on the outer end wall of the housing 200.

[0136] It is understood that the screen assembly also includes a movable connector; the storage position 240 and the first opening 220 are both located on one end face of the housing 200, the storage position 240 is located on one side of the first opening 220, and the movable connector is disposed at the first mounting position or the second mounting position of the storage position 240; the second mounting position is located away from the first opening 220 from the first mounting position and is spaced apart from the first mounting position.

[0137] Referring to Figures 20, 21 and 22, the screen 10 and the first opening 220 are located on the same end face of the housing 200, and the storage position 240 is located on one side of the first opening 220. Specifically, the movable connector can be a hinge structure, such as a hinge or a hinge ring. Of course, the movable connector can also be a cross pivot structure, so that the screen 10 can rotate around a horizontal pivot or around a vertical pivot, so that the display surface and the back shell surface of the screen 10 can face different directions, thereby increasing the degree of rotation of the screen 10.

[0138] Referring to Figures 15 and 16, when the hinge structure connecting the screen 10 is in the first mounting position, when the screen 10 is rotated to the limit position, it does not interfere with the sound column assembly 100, thus avoiding collision between the screen 10 and the sound column assembly 100 during use.

[0139] Referring to Figures 21 and 22, when the hinge structure connecting the screen 10 is in the second mounting position, it can prevent the screen 10 from colliding with the extended sound column assembly 100 when it is flipped, and can reduce the degree to which the screen 10 is blocked by the sound column assembly 100 during use.

[0140] Referring to Figures 6, 7, 15, and 20, specifically, the third opening for placing the microphone can be set on the bottom wall of the storage compartment 240 so that the third opening can be closed through the screen to protect the microphone.

[0141] Referring to Figures 1 to 39, according to a second aspect embodiment of the present invention, the automatic raising and lowering control method for a sound column includes the following steps:

[0142] S1: The first preset condition has been detected, and the sound column rises;

[0143] S2: Second preset condition detected, adjust the height of the sound column;

[0144] S3: The third preset condition has been detected, and the sound column has dropped.

[0145] The automatic raising and lowering control method of the sound column can control the sound column to rise or fall under the first, second, and third preset conditions, so as to adjust the height of the sound column.

[0146] Specifically, the automatic raising and lowering control method for the sound column according to the second aspect of the present invention can be applied to the intelligent audio device according to the first aspect, as shown in FIG39:

[0147] Upon detecting the first preset condition, the drive component 300 drives the sound column assembly 100 to rise; specifically, the drive component 300 can drive the sound column housing 110 and / or the sound column body 120 to rise.

[0148] Upon detecting the second preset condition, the drive component 300 drives the sound column assembly 100 to rise or fall, thereby adjusting the height of the sound column assembly 100. Specifically, the drive component 300 can drive the sound column housing 110 and / or the sound column body 120 to rise, or it can drive the sound column housing 110 and / or the sound column body 120 to fall.

[0149] Upon detecting a third preset condition, the drive component 300 drives the sound column assembly 100 to descend. The drive component 300 can drive the sound column housing 110 and / or the sound column body 120 to descend.

[0150] It is understood that the first preset condition includes at least one of the following: power on; power on and the speaker receives an upward command; power on and the environment meets the upward condition; the second preset condition includes: audio information of the file content and / or playback space environment parameters; the third preset condition includes at least one of the following: power off; power level less than or equal to the power preset value; power on and receives a downward command; power on and the environment meets the downward condition.

[0151] When the smart audio device needs to be used, it must first be powered on. Upon detecting power-on, the drive component 300 drives the speaker column assembly 100 to rise. Furthermore, when the height of the speaker column assembly 100 needs to be adjusted, a rise command can be issued to the speaker column assembly 100 upon power-on. Upon receiving the rise command, the drive component 300 drives the speaker column assembly 100 to rise. The speaker column assembly can receive the command via voice, buttons, scroll wheel, infrared gesture sensing, or other mechanical sensing. Specifically, when the speaker column assembly 100 receives a misreceived rise correction command, the drive component 300 stops driving the speaker column assembly 100 to rise and lowers it back to its previous height. Specifically, the drive component 300 can be set with a preset rise mode. After receiving the rise command, the speaker column assembly 100 can automatically adjust its height according to the user-selected mode, and can move to the predetermined height under the drive of the drive component.

[0152] When the power is on and the surrounding environment meets the conditions for rising, the drive component 300 drives the speaker column assembly 100 to rise. Specifically, meeting the conditions for rising can mean whether there is sufficient space above the speaker column assembly 100 to allow it to rise and avoid collisions with structures above it. Therefore, a distance sensor can be provided to determine whether there is sufficient space above the speaker column assembly 100. When there is sufficient space, the drive component 300 drives the speaker column assembly 100 to rise and move to a second position, or even to the highest position, as is the case with smart audio devices. Located in an outdoor environment; of course, the distance sensor can also determine whether there is enough space around the speaker assembly 100 to avoid collision between the speaker assembly 100 and its surrounding structures; specifically, referring to Figures 36 and 37, when using a smart audio device indoors, after the speaker assembly 120 extends from the first receiving position 210, the distance between the speaker assembly 120 and the ceiling of the room is h1, and the distances between it and the surrounding walls are h2 and h3, respectively. When the values ​​of h1, h2 and h3 are less than a predetermined distance, the drive assembly 300 drives the speaker assembly 100 to retract into the first receiving position 210 to protect the speaker assembly 100.

[0153] The distance sensor can be installed on the housing 200 or on the sound column assembly 100. When the drive assembly 300 drives the sound column assembly 100 to rise, it can drive the sound column assembly 100 to move to a predetermined position or to the highest position, depending on the specific situation.

[0154] Specifically, the surrounding environment meeting the conditions for rising can be whether the speaker column assembly 100 is in an excessively tilted state. For example, if the smart audio device is placed on an uneven outdoor grassy area, when the drive component 300 drives the speaker column assembly 100 to rise, the center of gravity of the smart audio device will change. To prevent the smart audio device from tipping over, a level sensor can be installed. The level sensor can determine whether the speaker column assembly 100 is in an excessively tilted state. When the level sensor determines that the speaker column assembly 100 is in an excessively tilted state, the drive component 300 stops driving the speaker column assembly 100 to rise. The smart audio device can be equipped with a support, and the drive component 300 drives the speaker column assembly 100 to rise.

[0155] Specifically, after the smart audio device is connected to multiple other speakers, the greater the distance between the smart audio device and the other speakers, the higher the drive component 300 drives the sound column component 100 to rise. When the smart audio device is connected to two or three or more speakers, they are generally distributed at equal intervals. The greater the distance between the smart audio device and the adjacent speakers, the higher the drive component 300 drives the sound column component 100 to rise.

[0156] When the smart audio device is needed, it is necessary to read the audio information of the file content, detect the audio information of the file content, and, based on other audio information such as frequency, loudness, pitch and timbre of the audio of the file content being played, drive the speaker column component 100 to rise or fall through the drive component 300 to adapt to different file content.

[0157] When the smart audio device is needed, the drive component 300 can drive the speaker column assembly 100 to rise or fall according to the playback space environment parameters. Specifically, when there is sufficient space above the speaker column assembly 100 and the smart audio device is indoors, the drive component 300 drives the speaker column assembly 100 to rise to the highest position; when there is sufficient space above the speaker column assembly 100 and the smart audio device is indoors, the drive component 300 drives the speaker column assembly 100 to rise to a predetermined position.

[0158] When the smart audio device is needed, a descent command can be sent to the speaker column assembly 100 upon power-on. The speaker column assembly 100 receives the descent command, and the drive assembly 300 drives the speaker column assembly 100 to descend. The speaker column can receive the command via voice, buttons, scroll wheel, infrared gesture sensing, or other mechanical sensing. Specifically, when the speaker column assembly 100 receives a erroneous descent correction command, the drive assembly 300 stops driving the speaker column assembly 100 to descend and instead drives the speaker column assembly 100 to rise back to its previous height. Furthermore, the drive assembly 300 can be set with a preset descent mode. After receiving the descent command, the speaker column assembly 100 can automatically adjust its height according to the user-selected mode, and can descend to the predetermined height under the drive of the drive assembly.

[0159] When it is necessary to stop using the smart audio device, the power must first be turned off. When the power is detected to be on, the drive component 300 drives the speaker assembly 100 to descend and retract into the first receiving position 210. Furthermore, when the power level is less than or equal to the preset power value, the drive component 300 drives the speaker assembly 100 to descend and retract into the first receiving position 210. This is to prevent the speaker assembly 100 from remaining outside the first receiving position 210 after the power is lost, which would require manual retraction of the speaker assembly 100 into the first receiving position 210, thus reducing damage to the drive component 300. In addition, when the smart audio device is in a rainy environment, the drive component 300 drives the speaker assembly 100 to descend and retract into the first receiving position 210.

[0160] Specifically, a distance sensor can be provided to determine whether there is sufficient space above the speaker column assembly 100. When the space above the speaker column assembly 100 decreases, the drive assembly 300 drives the speaker column assembly 100 to descend, for example, when the smart audio device is in an upward movement state. Of course, the distance sensor can also determine whether there is sufficient space around the speaker column assembly 100. When an object approaches the speaker column assembly 100, the drive assembly 300 drives the speaker column assembly 100 to descend in order to avoid collision between the speaker column assembly 100 and its surrounding structures. The distance sensor can be located on the housing 200 or on the speaker column assembly 100. When the drive assembly 300 drives the speaker column assembly 100 to descend, it can move the speaker column assembly 100 to a predetermined position or into the first receiving position 210, depending on the specific situation.

[0161] Specifically, S2 detects the second preset condition, and adjusting the height of the speaker column is not a necessary step. The smart audio device can choose one of the following raising modes: when the device is powered on, the first preset condition is detected, and the speaker column rises to the highest position; when the device is powered off, the third preset condition is detected, and the speaker column falls to the lowest position, so that the speaker column is stored in the first receiving position 210.

[0162] Specifically, the drive assembly 300 can drive the sound column housing 110 and the sound column body 120 to rise and fall simultaneously, or the drive assembly 300 can drive the sound column housing 110 and the sound column body 120 to rise and fall separately.

[0163] Referring to Figures 26, 27, 28 and 29, it can be understood that the cross-sections of the first opening 220, the sound column body 120 and the sound column shell 110 are all non-circular surfaces.

[0164] Specifically, the outer wall of the sound column housing 110 abuts against the inner wall of the first opening 220, and the inner wall of the sound column housing 110 abuts against the outer wall of the sound column body 120, so that when the first screw 310 and the second screw 320 rotate synchronously, the sound column housing 110 and the sound column body 120 are prevented from rotating, thereby improving the stability of the sound column housing 110 and the sound column body 120 moving in the first direction.

[0165] Referring to Figures 1 and 3, specifically, the smart audio device also includes a front grille housing 30, a top housing 60, and a bottom housing 70. The top housing 60 and the bottom housing 70 are respectively disposed on opposite sides of the outer casing 200. Specifically, the top housing 60 and the bottom housing 70 are distributed vertically, with the outer casing 200 disposed in the middle. The outer casing 200 has a second receiving position 230 for accommodating the speaker assembly 40, and the top housing 60 has a second opening communicating with the second receiving position 230.

[0166] The orientation of the speaker assembly 40 can be the same as the orientation of the first housing 201, the sound output direction of the sound column assembly 100, and the sound output direction of the low-frequency speaker; multiple air ducts 20 can be provided, with the length direction of the air ducts 20 facing the first housing 201.

[0167] The front grille housing 30 is connected to the outer shell 200. The front grille housing 30 is in the shape of a fence panel. The front grille housing 30 can have various striped structures, such as wood grain, or can be made of various materials, such as wood. The front grille housing 30 is provided with a button area, on which various buttons can be set. By pressing the buttons, the smart audio device can be controlled.

[0168] The second housing 202 is provided with a mounting position for installing the front mesh housing 30. The front mesh housing 30 can be installed by plugging, snapping, gluing, screw fixing, hot melting, ultrasonic welding, or welding.

[0169] At least one recessed position 50 is provided on the rear side of the housing 200, and the recessed position 50 is used to set an interface or other structure.

[0170] The speaker assembly 40 in the second receiving position 230 preferably only operates as a low-frequency speaker. With the two-stage lifting of the sound column assembly 100, the high frequency and full frequency of the sound column assembly 100 have met the requirements of the sound field. Moreover, the distance between the speaker assemblies 40 is maximized, the sound field has been fully released and strengthened, and the diffusion range has reached its limit.

[0171] In some embodiments, the smart audio device is provided with a storage structure. The storage structure can be a cavity for accommodating and storing a microphone, with the microphone inserted into the cavity. The cavity depth is greater than or equal to the microphone length. The microphone-storing cavity includes a third opening through which the microphone is inserted vertically or horizontally along its length direction into the cavity for storage. A microphone fixing structure can be provided inside or outside the third opening to fix the microphone after storage. The third opening can be located at any position on the smart audio device, including the top, side, and bottom surfaces of the smart audio device. Alternatively, the storage structure can be a groove into which the microphone is fitted. This is a microphone-insertion storage, with a microphone fixing structure provided inside or outside the groove to fix the microphone after storage. The microphone is inserted vertically or horizontally along its length into the groove for storage. The groove can be located at any position on the smart audio device, including the top, side, and bottom surfaces of the smart audio device.

[0172] Referring to Figures 4, 15, and 16, the microphone storage can be either automatic or manual. Specifically, the housing 100 may contain a third opening, a cylindrical body, and a motor structure. The cylindrical body has a receiving space for accommodating the microphone, which can be inserted into the cylindrical body through the third opening. The cylindrical body is positioned within the second receiving position 230 and at the third opening. The motor is connected to the cylindrical body to drive it to move up and down, thus achieving automatic microphone storage. Alternatively, the housing 100 may contain a third opening and a cylindrical body, with the cylindrical body having a receiving space for accommodating the microphone, allowing the microphone to be inserted into the cylindrical body through the third opening for manual storage.

[0173] In some implementations, the microphone automatically shuts down by a sensing element detecting the distance between the smart audio device and the microphone. Once the sensing element detects that the distance is less than or equal to a preset distance, the microphone automatically shuts down. The sensing element can be one or more, and can be a Hall effect sensor, a proximity sensor, an infrared sensor, or any other single electronic component capable of sensing the distance between the smart audio device and the microphone, or any combination of electronic components. The sensing element can be located on the smart audio device and / or the microphone. Specifically, when the microphone is inserted into the cavity, the sensing element can be located at the third opening of the cavity housing the microphone, so that the microphone shuts down immediately upon insertion into the third opening. The sensing element can also be located at the end of the cavity away from the third opening to prevent the sensing element from being exposed and aging due to the third opening facing outwards. When the microphone is fitted into the groove, the sensing element can be located at one end, the middle, or both ends of the groove.

[0174] In some specific embodiments, the sensing element is a Hall element. The storage structure of the smart audio device and the microphone each have corresponding positions. A magnetic element is set at the corresponding position of the microphone, and a Hall element is set at the corresponding position of the smart audio device; alternatively, a Hall element is set at the corresponding position of the microphone, and a magnetic element is set at the corresponding position of the smart audio device. The trigger condition for the Hall element can be that the detected magnetic field strength reaches a preset value. When the detected magnetic field strength is greater than or equal to the preset value, it means that the distance between the smart audio device and the microphone meets the requirement to trigger feedback, and the microphone needs to be turned off. Preferably, a magnetic element is set at the corresponding position of the microphone, and a Hall element is set at the corresponding position of the smart audio device. Since the microphone moves around during karaoke, it may move to other places with strong magnetic fields. Setting a Hall element on the microphone may cause the microphone to turn off incorrectly, thus affecting the experience. The microphone can be inserted into the storage, and the Hall element is set at the third opening or at the end away from the third opening; of course, the microphone can also be placed into the storage, and the Hall element is set at one end, the middle, or both ends of the groove.

[0175] In some specific implementations, the sensing element is a Hall element. The smart audio device is equipped with a corresponding charging structure, and the microphone is equipped with a corresponding power receiving structure. The trigger condition for the Hall element can be the change in magnetic field caused by the instantaneous power-on when the microphone is charging. When the change in magnetic field is detected, it means that the distance between the smart audio device and the microphone meets the requirement to trigger a howling sound, and the microphone needs to be turned off. The charging structure can be set on the surface of the smart audio device or corresponding to the storage structure. The microphone can be inserted into the storage, with the charging structure set at the end of the cavity structure of the smart audio device away from the third opening. The bottom or end face of the microphone is correspondingly equipped with a power receiving structure, and the Hall element is set near the charging structure. The Hall element only needs to be able to sense the change in magnetic field caused by the instantaneous power-on. Alternatively, the microphone can be placed into the storage, with the charging structure set at one end, the middle, or both ends of the groove in the smart audio device. The microphone is equipped with a corresponding power receiving structure, and the Hall element is set near the charging structure. The Hall element only needs to be able to sense the change in magnetic field caused by the instantaneous power-on. The charging structure can be an inserted charging probe, and the contact can be one or more of a charging probe and a wireless charging structure.

[0176] In some specific embodiments, the sensing element is a Hall element, the smart audio device is provided with a corresponding charging structure, and the storage structure and microphone are each provided with magnetic components. The magnetic components fix the microphone and are located outside the sensing trigger range of the Hall element. The microphone can be placed into the storage compartment, and the charging structure is located at one end, the middle, or both ends of the groove in the smart audio device. The microphone is provided with a corresponding power receiving structure, and the Hall element is located near the charging structure. The Hall element can sense the change in magnetic field caused by the instantaneous power-on. Preferably, the charging structure is located at the bottom of the first receiving groove, and the magnetic component is located at the other end or the middle of the first receiving groove. When the microphone is cylindrical, a button is provided on the microphone surface, and the magnetic component is located on the side opposite to the button, so that the microphone button faces outward from the groove.

[0177] Specifically, in order to prevent the microphone from damaging the structure of the screen 10 on the smart audio device, a sensing structure can be set up. When the screen is off, the sensing structure can sense the position of the screen 10 structure, causing the microphone to drop down quickly, or prompting the user through a speaker that there may be interference between the microphone and the screen 10.
