[0071] Reference below Figures 1 to 39 The intelligent audio device and the automatic lifting control method of the sound column according to the present invention are described.

[0072] According to an intelligent audio device of an embodiment of the first aspect of the present invention, the intelligent audio device includes a sound column assembly 100, a shell 200 and a driving assembly 300; the shell 200 is provided with at least one first accommodating position 210; one end of the first accommodating position 210 extends to the outer wall of the shell 200 to form a first opening 220; the first accommodating position 210 is used to accommodate the sound column assembly 100; the driving assembly 300 is connected to the sound column assembly 100, and the driving assembly 300 can drive the sound column assembly 100 to reciprocate between a first position and a second position; wherein, when the sound column assembly 100 is located in the first position, the sound column assembly 100 is located in the first accommodating position 210; when the sound column assembly 100 is located in the second position, the sound column assembly 100 is at least partially located outside the first accommodating position 210.

[0073] The sound column assembly 100 is located in the first accommodation position 210, and the housing 200 can accommodate the sound column assembly 100 through the first accommodation position 210. When the sound column assembly 100 needs to be used, the driving 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 located in the second position, the sound column assembly 100 is at least partially located outside the first accommodation position 210, so that the sound column assembly 100 can be used normally. The driving 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 located in the first position, the sound column assembly 100 It moves to the first accommodating position 210 to accommodate the sound column assembly 100. Compared with the plug-in sound column and speaker structure, the intelligent audio device of the present invention can drive the sound column assembly 100 to move and reciprocate between the first position and the second position through the driving assembly 300. It is more convenient to use and has better stability in use. It can intelligently convert the sound field and adjust the degree of freedom. Moreover, since the intelligent audio device of the present invention is connected to the sound column assembly 100 through the driving assembly 300, there is no need to assemble the sound column assembly 110, and it can be used immediately after opening, which makes it more convenient to use and can also reduce transportation costs without separate packaging and transportation.

[0074] Specifically, refer to Figure 3 and Figure 4 The first accommodating position 210 may be a cavity structure formed by five or fewer sides, wherein the first accommodating position 210 may be a cavity structure formed by four sides; of course, the first accommodating position 210 may 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 the storage remains unchanged, and the sound column assembly 100 is completely stored in the shell 200, and the stored sound column assembly 100 cannot be seen from outside the shell 200.

[0075] Specifically, refer to Figure 2The first position is the horizontal plane position of the first opening 220, and the second opening is a preset height position from the horizontal plane of the first opening 220 or the bottom of the speaker; taking the horizontal plane from the first opening 220 as an example, the height position can be 75cm to 120cm.

[0076] Specifically, the top surface of the sound column assembly 100 is used as a determination condition. When the sound column assembly 100 is located at the first position, the top surface of the sound column assembly 100 is located at or below the first position. When the sound column assembly 100 is located at the second position, the distance between the top surface of the sound column assembly 100 located at the second position and the first position is the preset distance.

[0077] Specifically, the driving assembly 300 drives the sound column assembly 100 to move so that the sound column assembly 100 is at least partially located outside the first accommodation position 210, wherein the driving assembly 300 drives the sound column assembly 100 to move in a vertical direction to be located outside the first accommodation position 210, or to move in a horizontal direction to be located outside the first accommodation position 210, and of course, to be located outside the first accommodation position 210 in any direction.

[0078] Specifically, the first opening 220 may be an open opening structure, which is never closed, so that the sound column assembly 100 can be conveniently extended in and out from the first opening 220; after the sound column assembly 100 is stored in the first accommodation position 210, the top end of the sound column assembly 100 can close the first opening 220, so as to prevent foreign matter from falling into the first accommodation position 210 from the first opening 220; of course, according to specific circumstances, a selective closing structure may be provided at the first opening 220, and the first opening 220 may be closed according to circumstances through the selective closing structure. The closing structure may be composed of a cover plate and a rotating shaft, the rotating shaft is connected to the housing 200, and the cover plate may be rotatably connected to the rotating shaft. Rotating the cover plate may enable the cover plate to rotate to close the first opening 220, and when the sound column assembly 100 extends out of the first opening 220, the cover plate may be pushed open. By providing the cover plate, the first opening 220 may be closed, thereby improving the protection capability.

[0079] Reference Figure 1 and Figure 2 It can be understood that the sound column assembly 100 includes a sound column body 120 and a sound column housing 110, and the sound column body 120 is connected to the sound column housing 110; the driving assembly 300 is drivingly 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.

[0080] The driving assembly 300 is drivingly connected to the sound column housing 110, so that when the driving assembly 300 drives the sound column housing 110 to move, 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.

[0081] Specifically, the sound column housing 110 is disposed outside the sound column body 120 , so that the sound column body 120 can be protected by disposing the sound column housing 110 , and the sound generating unit of the sound column assembly 100 can be disposed inside the sound column body 120 .

[0082] Whether the rear cavity space is effectively sealed has a great influence on the low-frequency part of the sound, and the low-frequency part of the sound has a great influence on the sound quality. The further to the left the low-frequency peak is, the more prominent the bass is, and subjectively the sound will be felt to be more pleasant. Generally, as the volume of the rear cavity space continues to increase, the low-frequency peak of its frequency response curve will continue to move to the left, so that the low-frequency characteristics can be improved. However, when there is a leak in the rear cavity space, the low frequency will attenuate, causing damage to the sound quality. The degree of influence caused by the leakage of the rear cavity space has a certain relationship with the leakage area and position. Generally, the larger the leakage area of ​​the rear cavity space, the more severe the low-frequency attenuation, and the leakage area and the attenuation of the low-frequency resonance point are in an approximately linear relationship. Under the condition of the same leakage area, the smaller the rear cavity space, the more severe the low-frequency attenuation, that is, the greater the harm caused by the leakage.

[0083] Reference Figure 8 and Fig. 9 According to the specific actual situation, the driving component 300 can be connected to the sound column shell 110 and the sound column body 120. Specifically, the driving component 300 is built into the sound column body 120 and is arranged outside the sound column body 120 to connect with the sound column shell 110. The driving component 300 first pushes the sound column body 120 to rise, and then the transmission shell 110 to rise; the driving component 300 can first push the transmission shell 110 to drop, and then the sound column body 120 to drop.

[0084] Reference Figure 8 and Fig. 9 Of course, the driving assembly 300 can be provided with multiple motors to cooperate with multiple screws to respectively push the sound column housing 110 and the sound column body 120 up and down, so that the driving assembly 300 can drive the sound column body 120 to extend from the first opening 220 to the outside of the first accommodation position 210, while the sound column housing 110 is still located in the first accommodation position 210, and the driving assembly 300 can also drive the sound column housing 110 to extend from the first opening 220 to the outside of the first accommodation position 210, while the sound column body 120 is still located in the sound column housing 110.

[0085] According to specific actual conditions, the driving component 300 can be connected to the sound column body 120; the sound column body 120 and the sound column housing 110 are in contact with each other. After the driving component 300 drives the sound column body 120 to rise, the sound column housing 110 can be driven to rise together, until the sound column housing 110 rises to the bottom of the sound column housing 110 and is lifted to the first opening. The rising position of the sound column housing 110 is limited by the outer shell 100, and the sound column body 120 continues to rise to its predetermined position; after the driving component 300 drives the sound column body 120 to descend, the sound column housing 110 can be driven to descend together, until the sound column housing 110 descends to its predetermined position. The descending position of the sound column housing 110 is limited by the outer shell 100, and the sound column body 120 continues to descend to its predetermined position. The sound column body 120 continues to descend to its first accommodating position 210.

[0086] Reference Fig.26 and Fig.29 Specifically, a sliding block 101 may be provided in the sound column housing 110, and a sliding groove 102 may be provided outside the sound column body 120. The sliding block 101 may be slidably provided in the sliding groove 102, so as to limit the stability of relative sliding between the sound column housing 110 and the sound column body 120; wherein the sliding block 101 may be a rack, so that the sound column body 120 and the sound column housing 110 are closely matched, thereby reducing the gap between the two.

[0087] Reference Fig.23 , Fig.24 and Fig.25 Specifically, the driving assembly 300 can drive the sound column body 120 and the sound column housing 110 to move, so that the sound column housing 110 can be partially moved from the first opening 220 to the outside of the first accommodation position 210, and the sound column body 120 can be partially moved to the outside of the sound column housing 110, so that the sound column assembly 100 moves to between the first position and the second position.

[0109] Since the height of the sound column assembly 100 itself can be relatively high in the first accommodating position 210 which is relatively high, the sound column assembly 100 can also be raised relatively high; Figures 30 to 35 It can be understood that the driving assembly 300 includes a third screw and a driving member 301, and the driving member 301 is drivingly 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 driving member 301 drives the third screw to rotate to drive the sound column housing 110 and the sound column body 120 to reciprocate, or, 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 driving member 301 drives the third screw to rotate to drive the sound column body 120 to reciprocate.

[0112] Reference Fig.34 and Fig.35 Specifically, the third screw can pass through the sound column body 120 and be threadedly connected with the sound column body 120. The driving member 301 drives the third screw to rotate to drive the sound column body 120 and the sound column housing 110 to reciprocate simultaneously. On this basis, the setting of the sound column housing 110 is cancelled to simplify the structure of the sound column assembly 100 and reduce the weight of the sound column assembly 100.

[0115] Specifically, the first lifting nut 112 can be arranged at the outer position of the first body 111 to prevent the first screw 310 from affecting the sound-emitting element inside the first body 111. The first lifting nut 112 can also be arranged inside the first body 111 to save the space occupied by the sound column assembly 100. The second lifting nut 122 can be arranged at the outer position of the second body 121 to prevent the second screw 320 from affecting the sound-emitting element inside the second body 121. The second lifting nut 122 can also be arranged inside the second body 121 to save the space occupied by the sound column assembly 100.

[0118] Specifically, the axial directions of the first screw rod 310 and the second screw rod 320 are arranged in the same direction; the second screw rod 320 is located in the sound column housing 110 so that the second screw rod 320 can be protected by the sound column housing 110 .

[0120] A placement cavity 117 is defined and formed between the limiting member 116 and the first main body 111. The placement cavity 117 can limit the position of the connecting member 114. Since the connecting member 114 is connected to the second screw 320, the position of the second screw 320 can be limited. When the second screw 320 rotates driven by the first screw 310, the connecting member 114 can also rotate in the placement cavity 117.

[0121] When the sound column housing 110 moves along the first direction, since the connecting member 114 can abut against the inner wall of the placement cavity 117 along the first direction, the inner wall of the placement cavity 117 can abut against the connecting member 114, so that the second screw 320 can be pushed to move relative to the first screw 310, so that the second screw 320 is driven to move when the sound column housing 110 moves, and since the second screw 320 is threadedly connected with the sound column body 120, the second screw 320 can drive the sound column body 120 to move along the first direction; a gap can be set between the connecting member 114 and the inner wall of the placement cavity 117, and the connecting member 114 and the inner wall of the placement cavity 117 can directly abut or indirectly abut, wherein a filler can be placed in the gap that can be set between the connecting member 114 and the inner wall of the placement cavity 117 to achieve indirect abutment.

[0122] Specifically, the driving member 301 drives the first screw 310 to rotate, so that the sound column housing 110 can move in the first direction, and 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 in 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 are simultaneously extended from the first opening 220 to the outside of the first accommodation position 210; because when the driving member 301 drives the first screw 310 to rotate, it can drive the second screw 320 to rotate, and can make the sound column body 120 move relative to the sound column housing 110 in the first direction, so that the sound column body 120 is extended from the inside of the sound column housing 110 to the outside of the sound column housing 110.

[0129] After the sound column assembly 100 is raised, the sound column body 120 is located at the second position and outside the first accommodation position 210. A rear cavity space is defined between the shell 200 and the end of the sound column housing 110 away from the sound column body 120, and the shell 200 closes the bottom of the sound column assembly 100, which not only ensures the stability of the air pressure inside the shell 200, but also expands the volume of the rear cavity space. A low-frequency speaker is also arranged in the first accommodation position 210. The shell 200 remains in a sealed state to prevent low-frequency attenuation, and the expansion of the volume of the rear cavity space can make the low-frequency peak larger. To the left, the bass is more prominent, improving the sound quality; and, in order to ensure the airtightness of the rear cavity space, fillers such as EVA, silicone, etc. can be arranged between the outer shell 200 and the sound column shell 110, and between the sound column shell 110 and the sound column body 120 to improve the airtightness of the rear cavity space and reduce the degree of leakage of the rear cavity space; wherein, the second accommodating position 230 is arranged in communication with the first accommodating position 210, so that the second accommodating position 230 and the first accommodating position 210 can both be used as the rear cavity space, so as to further increase the volume of the rear cavity space.

[0130] Specifically, after the driving assembly 200 drives the sound column housing 110 to move upward, the rear cavity space is defined and formed 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 by itself without the driving assembly 200 driving the sound column housing 110 to move upward.

[0131] Reference Figure 3 Specifically, the housing 200 is composed of a first shell 201 and a second shell 202 , wherein the first accommodation position 210 is arranged in the first shell 201 , the first opening 220 is arranged on the first shell 201 , and the second accommodation position 230 is arranged in the second shell 202 .

[0135] The screen 10 is installed outside the outer shell 200 through a hinge structure, and can also be installed outside the top shell 60 or the bottom shell 70.

[0136] Reference Figure 2 Specifically, the microphone, the microphone storage structure, the low-frequency speaker and the screen assembly can be arranged on the same side of the housing 200, while the sound 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 sound column assembly 100 is raised; wherein, the microphone, the microphone storage structure, the low-frequency speaker and the screen assembly can all be arranged on the front side of the housing 200, while the sound column assembly 100 is arranged on the rear side.

[0141] Reference Fig.15 and Fig.16 When the hinge structure connected to the screen 10 is located in the first installation position, when the flip screen 10 is located in the first installation position, the screen 10 does not interfere with the sound column assembly 100 when it is rotated to the extreme position, thereby avoiding collision between the screen 10 and the sound column assembly 100 during use.

[0153] It can be understood that the first preset condition includes at least one of the following: power is on; power is on and the sound column receives an ascending command; power is on and the environment meets the ascending 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 is off; power level is less than or equal to the power preset value; power is on and receives a descending command; power is on and the environment meets the descending condition.

[0154] When the smart audio device needs to be used, the power supply needs to be turned on first. When the power supply is detected to be turned on, the driving component 300 drives the sound column component 100 to rise; and, when the height of the sound column component 100 needs to be increased, the power supply can be turned on, and an ascending command can be issued to the sound column component 100. The sound column component 100 receives the ascending command, and the driving component 300 drives the sound column component 100 to rise; wherein, the sound column may receive the command by mechanical energy sensing of sensors such as voice, buttons, rollers, infrared sensing gestures, etc.; specifically, when the sound column component 100 receives an erroneous ascending correction command, the driving component 300 stops driving the sound column component 100 to rise, and the driving component 300 drives the sound column component 100 to descend to the height just located; specifically, the driving component 300 may be provided with an ascending preset mode. After the sound column component 100 receives the ascending command, the height can be automatically adjusted according to the mode selected by the user, and the sound column component 100 can be moved to a predetermined height on the drive of the driving component.

[0155] When the power is turned on and the surrounding environment meets the rising condition, the driving component 300 drives the sound column component 100 to rise; specifically, the surrounding environment meeting the rising condition may be whether the height space above the sound column component 100 is sufficient for the sound column component 100 to rise, so as to avoid the sound column component 100 from colliding with the structure above it. Therefore, a distance sensor may be provided, and the distance sensor may be used to determine whether the height space above the sound column component 100 is sufficient. When the height space above the sound column component 100 is sufficient, the driving component 300 drives the sound column component 100 to rise and move to the second position, or to the highest position, for example, the smart audio device is located in an outdoor environment; of course, the distance sensor may also determine whether the space around the sound column component 100 is sufficient to avoid the sound column component 100 from colliding with the structure around it; specifically, refer to Fig.36 and Fig.37 When the smart audio device is used indoors, after the sound column assembly 120 is extended from the first accommodation position 210, the distance between the sound column assembly 120 and the ceiling of the room is h1, and the distances from the surrounding walls are h2 and h3 respectively. When the values ​​of h1, h2 and h3 are less than the predetermined distances, the driving assembly 300 drives the sound column assembly 100 to be retracted into the first accommodation position 210 to protect the sound column assembly 100.

[0156] Among them, the distance sensor can be set on the housing 200, and can also be set on the sound column assembly 100; when the driving assembly 300 drives the sound column assembly 100 to rise, it can drive the sound column assembly 100 to move to a predetermined position according to specific circumstances, and can also drive the sound column assembly 100 to move to the highest position.

[0157] Specifically, the surrounding environment satisfies the rising condition by determining whether the sound column assembly 100 is in an excessively tilted state. For example, the smart audio device is placed on an uneven outdoor grassy area. When the driving assembly 300 drives the sound column assembly 100 to rise, the center of gravity of the smart audio device will change. In order to prevent the smart audio device from tipping over, a horizontal sensor may be provided. The horizontal sensor may be used to determine whether the sound column assembly 100 is in an excessively tilted state. When the horizontal sensor determines that the sound column assembly 100 is in an excessively tilted state, the driving assembly 300 stops driving the sound column assembly 100 to rise. The smart audio device may be installed with a support, and the driving assembly 300 drives the sound column assembly 100 to rise.

[0158] 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 height to which the driving component 300 drives the sound column component 100 to rise. When the smart audio device is connected to two or more speakers, they are generally evenly spaced. The greater the distance between the smart audio device and the adjacent speakers, the higher the height to which the driving component 300 drives the sound column component 100 to rise.

[0159] When the intelligent audio device needs to be used, the audio information of the file content needs to be read and detected. According to other audio information such as the frequency, loudness, pitch and timbre of the audio of the file content being played, the sound column component 100 can be driven up or down by the driving component 300 to adapt to different file contents.

[0160] When the smart audio device needs to be used, the driving component 300 can drive the sound column component 100 to rise or fall according to the playback space environment parameters; specifically, when the height space above the sound column component 100 is sufficient and the smart audio device is indoors, the driving component 300 drives the sound column component 100 to rise and move to the highest position; when the height space above the sound column component 100 is sufficient and the smart audio device is indoors, the driving component 300 drives the sound column component 100 to rise and move to a predetermined rising position.

[0161] When the smart audio device needs to be used, the power can be turned on, and a descending command can be issued to the sound column assembly 100. The sound column assembly 100 receives the descending command, and the driving assembly 300 drives the sound column assembly 100 to descend; wherein the sound column may receive the command by voice, button, roller, infrared sensing gesture or other sensor mechanical energy sensing; specifically, when the sound column assembly 100 receives the mistakenly received descending correction command, the driving assembly 300 stops driving the sound column assembly 100 to descend, and the driving assembly 300 drives the sound column assembly 100 to rise to the height just located; specifically, the driving assembly 300 may be provided with a descending preset mode, and after the sound column assembly 100 receives the descending command, the height can be automatically adjusted according to the mode selected by the user, and the sound column assembly 100 can be driven by the driving assembly to descend to a predetermined height.

[0162] When it is necessary to stop using the smart audio device, the power supply must be turned off first. When it is detected that the power supply is turned on, the driving component 300 drives the sound column component 100 to descend and retract into the first accommodation position 210; and, when the power supply level is less than or equal to the preset power supply value, the driving component 300 drives the sound column component 100 to descend and retract into the first accommodation position 210, so as to avoid the sound column component 100 being still outside the first accommodation position 210 after the power supply loses power, resulting in the need to manually retract the sound column component 100 into the first accommodation position 210, thereby reducing damage to the driving component 300; and, when the smart audio device is in a rainy environment, the driving component 300 drives the sound column component 100 to descend and retract into the first accommodation position 210.

[0163] Specifically, a distance sensor may be provided, by which it is possible to determine whether the height space above the sound column assembly 100 is sufficient. When the height space above the sound column assembly 100 decreases, the driving assembly 300 drives the sound column assembly 100 to descend, for example, the smart audio device is in an upward moving state; of course, the distance sensor may also determine whether the space around the sound column assembly 100 is sufficient. When there are objects around that are close to the sound column assembly 100, in order to avoid the sound column assembly 100 from colliding with the surrounding structures, the driving assembly 300 drives the sound column assembly 100 to descend; wherein, the distance sensor may be provided on the housing 200, or on the sound column assembly 100; when the driving assembly 300 drives the sound column assembly 100 to descend, it may drive the sound column assembly 100 to move to a predetermined position according to the specific situation, or it may drive the sound column assembly 100 to move into the first accommodation position 210.

[0164] Specifically, S2 detects the second preset condition, and adjusting the height of the sound column is not a necessary step. The smart audio device can choose an elevation mode: when the power is turned on, the first preset condition is detected, and the sound column rises to the highest position; when the power is turned off, the third preset condition is detected, and the sound column drops to the lowest position, so that the sound column is stored in the first accommodation position 210.

[0165] Specifically, the driving assembly 300 can drive the sound column housing 110 and the sound column body 120 to rise and fall simultaneously, or the driving assembly 300 can drive the sound column housing 110 and the sound column body 120 to rise and fall separately.

[0166] Reference Fig.26 , Fig. 27 , Fig.28 and Fig.29 It can be understood that the cross-sections of the first opening 220 , the sound column body 120 , and the sound column housing 110 are all non-circular surfaces.

[0167] 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 avoided from being driven to rotate, thereby improving the stability of the sound column housing 110 and the sound column body 120 moving in the first direction.

[0168] Reference Figure 1 and Figure 3 Specifically, the smart audio device also includes a front mesh shell 30, a top shell 60 and a bottom shell 70. The top shell 60 and the bottom shell 70 are respectively arranged on opposite sides of the outer shell 200. The top shell 60 and the bottom shell 70 are specifically distributed up and down, and the outer shell 200 is arranged in the middle. A second accommodating position 230 for accommodating the speaker assembly 40 is arranged in the outer shell 200, and the top shell 60 is provided with a second opening connected to the second accommodating position 230.

[0169] The orientation of the speaker assembly 40 may be consistent with the orientation of the first shell 201 , the sound direction of the sound column assembly 100 and the sound direction of the low-frequency speaker; a plurality of air ducts 20 may be provided, and the length direction of the air ducts 20 is toward the first shell 201 .

[0170] The front mesh shell 30 is connected to the outer shell 200. The front mesh shell 30 is in the shape of a fence plate. The front mesh shell 30 can have various striped structures, such as wood grain, and can also be made of various materials, such as wood. The front mesh shell 30 is provided with a button area, and various buttons can be set on the button area. The smart audio device can be controlled by pressing the buttons.

[0171] The second housing 202 is provided with an installation position for installing the front net housing 30. The front net housings 30 and the front net housings 30 can be installed by plugging, clamping, gluing, screwing, hot melting, ultrasonic welding, or welding.

[0172] At least one recessed position 50 is disposed on the rear side of the housing 200 , and the recessed position 50 is used to dispose an interface or other structures.

[0173] The speaker assembly 40 of the second accommodating position 230 preferably only operates the low-frequency speaker. In the case of 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 the limit.

[0174] In some embodiments, the smart audio device is provided with a storage structure, which can be a cavity for accommodating and storing a microphone. The microphone is inserted into the cavity, and the depth of the cavity is greater than or equal to the length of the microphone. The cavity for storing the microphone includes a third opening. Through the third opening, the microphone is vertically or horizontally inserted into the cavity along the length direction to achieve storage. A microphone fixing structure can be set inside or outside the third opening to fix the microphone after it is stored. The third opening can be set at any position of the smart audio device, including the top, side, and bottom surface of the smart audio device. The storage structure can also be a groove, and the microphone is embedded in the groove. The microphone is inserted into the groove. A microphone fixing structure can be set inside or outside the groove to fix the microphone after it is stored. The microphone is vertically or horizontally inserted into the groove along the vertical direction of the length to achieve storage. The groove can be set at any position of the smart audio device, including the top, side, and bottom surface of the smart audio device.

[0176] In some embodiments, the microphone is automatically turned off by a sensing element sensing the distance between the smart audio device and the microphone. After sensing that the distance between the smart audio device and the microphone is less than or equal to a preset distance, the microphone automatically turns off. The sensing element may be one or more, and the sensing element may be a Hall element, a distance sensor, an infrared sensor, or any other single electronic element that can sense the distance between the smart audio device and the microphone, as well as any combination of electronic elements. The sensing element may be disposed on the smart audio device and / or the microphone. Specifically, when the microphone is inserted into the cavity, the sensing element may be disposed at the third opening of the cavity that accommodates the microphone, so that when the microphone is just inserted into the third opening, the microphone is turned off immediately. The sensing element may also be disposed at one end of the cavity away from the third opening to prevent the sensing element from being exposed to the outside due to the third opening facing outward, resulting in aging of the element. When the microphone is fitted into the groove, the sensing element may be disposed at one end, the middle, or both ends of the groove.

[0177] In some specific embodiments, the sensing element is a Hall element, the storage structure of the smart audio device and the microphone each have a corresponding position, a magnetic part is set at the corresponding position of the microphone and a Hall element is set at the corresponding position of the smart audio device, or a Hall element is set at the corresponding position of the microphone and a magnetic part is set at the corresponding position of the smart audio device. The triggering condition of 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 of causing howling, and the microphone needs to be turned off. Preferably, a magnetic part 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 everywhere during karaoke, it may move to other places with large magnetic field strength. The Hall element set on the microphone may cause the microphone to shut down incorrectly, thereby affecting the experience. The microphone can be inserted into the storage, and the Hall element is set at the third opening or at one end away from the third opening; of course, the microphone can be inserted into the storage, and the Hall element is set at one end, the middle, or both ends of the groove.

[0178] In some specific embodiments, the sensing element is a Hall element, the smart audio device is provided with a charging structure, and the microphone is provided with a power receiving structure. The triggering condition of the Hall element can be a magnetic field change caused by the moment of power on when the microphone is charged. When the magnetic field change is detected, it means that the distance between the smart audio device and the microphone is sufficient to cause howling, and the microphone needs to be turned off. The charging structure can be set on the surface of the smart audio device, or it can be set corresponding to the storage structure. The microphone can be inserted into the storage, and the charging structure is set at the end of the cavity structure of the smart audio device away from the third opening. The power receiving structure is correspondingly set at the bottom or the bottom surface of the end of the microphone. The Hall element is set near the charging structure, and the Hall element can sense the magnetic field change caused by the moment of power on; the microphone can be inserted into the storage, and the charging structure is set at one end, the middle, or both ends of the groove of the smart audio device.

When the microphone is cylindrical, a button is provided on the surface of the microphone, and the magnetic member is provided on the other side opposite to the button, so that the microphone button faces the outside of the groove.

[0180] 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. When the screen is turned off, the sensing structure can sense the position of the structure of the screen 10, causing the microphone to drop quickly, or prompt the user through the speaker that the microphone and the screen 10 may interfere with each other.
