Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to a height-adjustable microphone and a smart speaker. Background Technology

[0002] In daily life, microphones are usually used in conjunction with speakers. Microphones are generally detachable and placed on a microphone stand or stored inside a speaker. Speakers usually have sleeves for inserting and storing microphones. When the microphone is not in use, it is inserted into the sleeve, making it convenient to carry and store.

[0003] Existing speaker enclosures typically feature a manual or electric lift-up and retraction mechanism at the bottom of the microphone sleeve. This mechanism secures the microphone when it is retracted into the speaker sleeve, allowing for easy lifting and retraction. However, this lift-up and retraction mechanism occupies a significant amount of space within the speaker enclosure, impacting its spatial layout. Utility Model Content

[0004] The main purpose of this utility model is to provide a height-adjustable microphone and a smart speaker, aiming to solve the problem that setting the height-adjustable storage structure inside the speaker's sleeve would occupy a large amount of space and affect the speaker's spatial layout.

[0005] To achieve the above objectives, this utility model proposes a height-adjustable microphone, comprising:

[0006] Microphone body;

[0007] The microphone body is slidably inserted into the base;

[0008] A lifting device is provided between the microphone body and the base for adjusting the distance between the microphone body and the base;

[0009] The lifting device includes a reset component, a fixing component, and a hook component; the reset component is used to keep the microphone body and the base in a separated state; the fixing component is disposed at the bottom of the microphone body; the hook component is disposed at the base and is used to lock with the fixing component when subjected to force and colliding with the fixing component, thereby keeping the microphone body and the base in a locked state.

[0010] Optionally, the hook component includes a housing, a lever, and a swinging component. The housing is fixed to the base. One end of the lever is rotatably disposed inside the housing. The swinging component swings relative to the housing. One end of the swinging component is provided with a hook portion that engages with the fixed component, and the other end is provided with a locking portion that slides and locks along the lever.

[0011] Optionally, the fixing member is provided with a fixing groove with a horizontal opening, and the front end of the hook is provided with a roller. When the microphone body is subjected to force and moves downward, the roller rolls at the bottom of the fixing member and is engaged in the fixing groove through the opening of the fixing groove.

[0012] Optionally, the paddle is provided with a locking groove, and the locking part is a protrusion structure provided on the surface of the swing member. When the swing member swings, the locking part slides along the paddle to push the paddle to swing. The locking part slides into the locking groove, and the swing member locks with the paddle.

[0013] Optionally, the paddle has a guide block on the wall of the locking groove. The guide block extends along the swing direction of the locking part, and the locking part slides relative to the guide block. The guide block pushes the locking part to slide out of the locking groove, and the swinging member unlocks from the paddle.

[0014] Optionally, the swing member is provided with a first rotating shaft and a first driving member between the hook and the locking part. The first rotating shaft passes through the housing, the swing member swings around the first rotating shaft, and the first driving member is sleeved on the first rotating shaft and drives the swing member to swing in the opposite direction to reset.

[0015] Optionally, the hook component is further provided with a second rotating shaft and a second driving member. The second rotating shaft passes through the paddle and the housing respectively, and the second driving member is disposed between the paddle and the housing to drive the paddle to rotate in the opposite direction and reset.

[0016] Optionally, a first protruding edge is provided on the inner side of the lower end of the microphone body, and a second protruding edge is provided on the outer side of the upper end of the base. The upper edge of the first protruding edge abuts against the lower edge of the second protruding edge to prevent the base from detaching from the microphone body.

[0017] Optionally, a limiting protrusion is provided on the inner side of the lower end of the microphone body, and a limiting groove is provided on the outer side of the base. The limiting protrusion moves up and down along the limiting groove to restrict the rotation of the base.

[0018] A smart speaker includes a speaker body and the aforementioned liftable microphone, wherein the speaker body has a storage cavity for mounting the liftable microphone.

[0019] The beneficial effects of this utility model are as follows: This solution incorporates a lifting device inside the microphone, enabling the microphone to actively rise and fall, thus avoiding the impact on the internal space layout of the speaker caused by placing a lifting device inside the speaker enclosure. Furthermore, since the lifting device is integrated inside the microphone, when it malfunctions, only the microphone needs to be mailed in for repair or a new microphone can be directly replaced. This effectively avoids the problem of having to mail the entire speaker enclosure for repair when a lifting device built into the speaker enclosure malfunctions, reducing the burden on users.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0041] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, if the word "and / or" appears throughout the text, it means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0042] One embodiment of this utility model provides a height-adjustable microphone, see reference. Figures 1 to 10 The microphone body 1, base 2, and lifting device 3 are included. The end of the microphone body 1 is slidably inserted into the base 2. The lifting device 3 is disposed between the microphone body 1 and the base 2 and is used to adjust the distance between the microphone body 1 and the base 2. The lifting device 3 includes a reset member 33, a fixing member 31, and a hook member 32. The reset member 33 is used to keep the microphone body 1 and the base 2 in a separated state. The fixing member 31 is disposed at the bottom of the microphone body 1. The hook member 32 is disposed at the base 2 and is used to lock with the fixing member 31 when subjected to force and colliding with the fixing member 31, thereby keeping the microphone body 1 and the base 2 in a locked state.

[0043] This solution incorporates a lifting device 3 inside the microphone, enabling the microphone to actively rise and fall. This avoids the impact on the internal space layout of the speaker caused by placing the lifting device 3 inside the speaker enclosure. Furthermore, the lifting device 3 is integrated within the height-adjustable microphone. If the lifting device 3 malfunctions, the microphone can simply be mailed for repair or replaced directly, effectively avoiding the problem of having to mail the entire speaker enclosure for repair when the lifting device 3, which is built into the speaker enclosure, malfunctions, thus reducing the burden on users. The height-adjustable microphone in this solution is also convenient for storage and removal. When the microphone is inserted into the speaker enclosure for storage, the microphone body 1 moves closer to the base 2, and the fixing piece 31 and the latch 32 engage and lock, completing the microphone storage. When removing the microphone, pressing the microphone body 1 again unlocks the fixing piece 31 and the latch 32, and the reset piece 33 pops the microphone body 1 upwards. In this embodiment, a slot 13 is provided at the bottom of the microphone body 1, and the base 2 is slidably inserted into the slot 13, thereby realizing the relative lifting and lowering movement of the base 2 and the microphone body 1. The outer side wall of the base 2 slides against the groove wall of the slot 13, thereby preventing the base 2 and the microphone body 1 from swaying left and right relative to each other.

[0044] In this embodiment, the fixing member 31 is fixed to the bottom wall of the slot 13, and the hook member 32 is fixed to the base 2. When the microphone is stored in the speaker, the microphone body 1 is pressed down, the base 2 slides along the slot 13, and the hook member 32 collides with and engages with the fixing member 31, locking them in place. At this time, the hook member 32 remains locked, and the microphone body 1 remains locked relative to the base 2, preventing the microphone body 1 from being pulled upwards. When it is necessary to remove the microphone, the microphone body 1 is pressed down again, and the fixing member 31 pushes the hook member 32 downwards to switch the hook member 32 to the unlocked state. Under the reset force of the reset member 33, the microphone body 1 moves away from the base 2, the fixing member 31 separates from the hook member 32, and the microphone body 1 moves upwards to release the limit and pops out of the speaker surface for the user to remove.

[0045] refer to Figure 6 and Figure 7 The reset element 33 is a spring. The bottom wall of the slot 13 has a first limiting groove 131, and the base 2 has a second limiting groove 23. The first limiting groove 131 and the second limiting groove 23 are respectively positioned opposite each other. The two ends of the reset element 33 abut against the first limiting groove 131 and the second limiting groove 23, thereby preventing the reset element 33 from shifting during the retraction and reset process. Alternatively, the reset element 33 could be two repulsive magnets, simply to keep the base 2 and the microphone body 1 away from each other.

[0046] Further, refer to Figure 2 and Figure 3The latching member 32 includes a housing 321, a lever 322, and a swing member 323. The housing 321 is fixed to the base 2. One end of the lever 322 is rotatably disposed within the housing 321. The swing member 323 swings relative to the housing 321. One end of the swing member 323 is provided with a hook portion 3231 that engages with the fixing member 31, and the other end is provided with a locking portion 3232 that slides and locks along the lever 322. In this embodiment, the housing 321 and the base 2 can be fixedly connected by screws or adhesive. Both the paddle 322 and the swing member 323 are disposed inside the housing 321 and are rotatably connected to the housing 321. Specifically, the paddle 322 is located inside the housing 321, and one end of the paddle 322 is rotatably connected to the housing 321, so that the paddle 322 swings around this end. The swing member 323 is located at the end of the housing 321 near the fixing member 31. The hook 3231 and the locking part 3232 swing around the middle position of the swing member 323. The hook 3231 extends out of the housing 321 and is used to engage with the fixing member 31. The locking part 3232 is located inside the housing 321 and abuts against the paddle 322. When the microphone body 1 is pressed closer to the base 2, the hook 3231 abuts against the fixing member 31, and under the push of the fixing member 31, the swing member 323 swings, so that both the hook 3231 and the locking member 3232 swing around the middle of the swing member 323. The hook 3231 engages with the fixing member 31, and the locking member slides along the lever 322 to the locked state. At this time, the swing member 323 cannot swing back to reset, and the fixing member 31 cannot disengage from the hook 3231, thereby locking the microphone body 1 relative to the base 2. When the microphone body 1 is pressed further, the fixing member 31 continues to push the swing member 323 to swing, so that the locking member 3232 continues to swing and switches to the unlocked state with the lever 322. At this time, the swing member 323 swings back to reset, and the fixing member 31 disengages from the hook 3231, thereby unlocking the microphone body 1 relative to the base 2.

[0047] In this embodiment, the rotational positions of the hook 3231, the locking part 3232, and the swing member 323 are such that the line connecting these three forms a triangle. Specifically, the angle between the hook 3231 and the rotation point, and between the locking part 3232 and the rotation point, is 90 degrees. This allows the hook 3231 to drive the swing member 323 to rotate around the rotation point when subjected to a downward thrust, thereby causing the locking part 3232 to swing synchronously. It can be understood that the angles between the hook 3231 and the rotation point, and between the locking part 3232 and the rotation point, can also be set to acute or obtuse angles, as long as the swing member 323 can swing under force.

[0048] Further, refer to Figure 4The fixing member 31 is provided with a fixing groove 311 with a horizontal opening. A roller is provided at the front end of the hook 3231. When the microphone body 1 is subjected to downward force, the roller rolls at the bottom of the fixing member 31 and engages with the fixing groove 311 through its opening. The roller at the front end of the hook 3231 can rotate, allowing it to roll and slide into the fixing groove 311 along its opening. In this embodiment, the opening of the fixing groove 311 is located on the side of the fixing member 31, making the fixing groove 311 a C-shaped groove structure. The fixing groove 311 is arc-shaped and has the same structure as the roller to facilitate the engagement of the roller.

[0049] When the fixing member 31 moves downward, the roller on the hook 3231 abuts against the upper opening edge of the fixing groove 311. Since the line connecting the rotation point of the hook 3231 and the swing member 323 is inclined in the vertical direction at this time, under the pressure of the fixing member 31, the roller on the hook 3231 rotates and slides along the groove wall of the upper opening edge of the fixing groove 311 until it enters the fixing groove 311. During the process of the roller on the hook 3231 entering the fixing groove 311, the swing member 323 swings to make the locking part 3232 slide along the lever 322. When the roller is fully inserted into the fixing groove 311, the locking part 3232 and the lever 322 just reach the locked state. At this time, the hook 3231 hooks the fixing member 31, preventing the microphone body 1 from moving upward. Of course, it should be noted that the front end of the hook 3231 can also be set as an arc-shaped protrusion. The hook 3231 slides against the edge of the opening of the fixing groove 311, so that the hook 3231 can also be inserted into the fixing groove 311 to achieve a locked state.

[0050] Further, refer to Figure 7 and Figure 10The paddle 322 is provided with a locking groove 3221, and the locking part 3232 is a protrusion structure provided on the surface of the swing member 323. When the swing member 323 swings, the locking part 3232 slides along the paddle 322 to push the paddle 322 to swing. The locking part 3232 slides into the locking groove 3221, and the swing member 323 and the paddle 322 are locked. In this embodiment, one end of the paddle 322 is rotatably connected to the housing 321, the locking groove 3221 is provided on the upper side of the other end of the paddle 322, and the locking part 3232 is a protrusion structure that abuts against the upper side of the paddle 322 and slides along the paddle 322. When the fixing member 31 pushes the hook 3231 downward to swing so that the hook 3231 is engaged in the fixing groove 311, the swing member 323 is squeezed and rotated, so that the locking part 3232 swings synchronously and slides along the upper side of the paddle 322. The swing path of the locking part 3232 is arc-shaped, and then the locking part 3232 pushes the paddle 322 to swing during the swing until the locking part 3232 slides to the position of the locking groove 3221 on the paddle 322. The locking part 3232 is engaged in the locking groove 3221, so that the swing member 323 and the paddle 322 are locked. Neither the paddle 322 nor the swing member 323 can swing back to reset. The microphone body 1 and the base 2 are locked.

[0051] Furthermore, the paddle 322 has a guide block 3222 on the groove wall of the locking groove 3221. The guide block 3222 extends along the swing direction of the locking part 3232, and the locking part 3232 slides relative to the guide block 3222. The guide block 3222 pushes the locking part 3232 out of the locking groove 3221, and the swinging member 323 unlocks from the paddle 322. In this embodiment, the guide block 3222 abuts against the locking part 3232 and guides the locking part 3232 to slide out of the locking groove 3221. The guide block 3222 extends obliquely along the swing direction of the locking part 3232, and extends from the middle of the locking groove 3221 to the outer edge of the locking groove 3221. After the locking part 3232 is engaged in the locking groove 3221, it abuts against the guide block 3222. When it is necessary to unlock the microphone body 1 and the base 2, push the microphone body 1 downward. The locking part 3232 continues to swing and slide along the guide block 3222. Since the guide block 3222 extends to the edge of the opening of the locking groove 3221, the locking part 3232 slides out of the locking groove 3221 under the guidance of the guide block 3222. At this time, the locking part 3232 and the paddle 322 are in the unlocked state. The swinging part 323 can swing back to reset, so that the hook part 3231 swings back to slide out of the fixing groove 311, thereby unlocking the microphone body 1 and the base 2.

[0052] It should be noted that the locking part 3232 and the lever 322 can also be unlocked in other ways. For example, the locking part 3232 can be a spherical protrusion structure provided at the end of the swing member 323, and the locking groove 3221 on the lever 322 can be a conical groove structure. When the spherical locking part 3232 is inserted into the conical locking groove 3221, the swing member 323 and the lever 322 are in a locked state. When the swing member 323 is pushed to continue swinging, the spherical locking part 3232 slides out of the locking groove 3221 along the arc-shaped groove wall of the locking groove 3221, so that the microphone body 1 and the base 2 are unlocked.

[0053] Furthermore, the swing member 323 is provided with a first rotating shaft 3233 and a first driving member 3234 between the hook portion 3231 and the locking portion 3232. The first rotating shaft 3233 passes through the housing 321, and the swing member 323 swings around the first rotating shaft 3233. The first driving member 3234 is sleeved on the first rotating shaft 3233 and drives the swing member 323 to swing back and reset. In this embodiment, the first rotating shaft 3233 passes through the swing member 323 and is located at the rotation point in the middle of the swing member 323. The two ends of the first rotating shaft 3233 are respectively engaged with the housing 321, so that the swing member 323 rotates relative to the housing 321 around the first rotating shaft 3233. The first driving element 3234 is a torsion spring, providing the swinging element 323 with a rotational force for reverse swinging and resetting. The first driving element 3234 is sleeved on the first rotating shaft 3233. One torsion arm of the first driving element 3234 is fixed to the swinging element 323, and the other torsion arm is fixed to the housing 321. When the swinging element 323 swings under the downward push of the fixing element 31, the first driving element 3234 accumulates a reverse elastic force. When the locking part 3232 slides out of the locking groove 3221 to switch to the unlocked state, the first driving element 3234 releases the elastic force to drive the swinging element 323 to swing and reset in the opposite direction, causing the hook part 3231 to slide out of the fixing groove 311 and return to its initial position. Of course, it can be understood that the first driving element 3234 can also be a tension spring, with both ends of the tension spring fixed to the swinging element 323 and the housing 321 respectively to provide a resetting force.

[0054] Furthermore, the hook member 32 is also provided with a second rotating shaft 324 and a second driving member 325. The second rotating shaft 324 passes through the paddle 322 and the housing 321 respectively, and the second driving member 325 is disposed between the paddle 322 and the housing 321 to drive the paddle 322 to rotate in the opposite direction and reset. In this embodiment, the second rotating shaft 324 passes through the paddle 322 and the housing 321 respectively, so that the paddle 322 swings relative to the housing 321 around the second rotating shaft 324. The second rotating shaft 324 is located at the end of the paddle 322. The second driving member 325 is sleeved on the second rotating shaft 324 and provides the paddle 322 with a driving force for swinging back and resetting. The second driving member 325 is a torsion spring, with one torsion arm of the second driving member 325 fixed to the paddle 322 and the other torsion arm fixed to the housing 321. The locking part 3232 abuts against the upper side of the paddle 322, and when the locking part 3232 swings, it synchronously pushes the paddle 322 downwards, allowing the locking part 3232 to engage in the locking groove 3221. At this time, the second driving member 325 accumulates a reverse elastic force. When the locking part 3232 slides out of the locking groove 3221, the limit of the reverse swing of the paddle 322 is released, and under the drive of the second driving member 325, the paddle 322 swings back to its original position around the second rotating shaft 324. It can be understood that the second driving member 325 can also be a tension spring.

[0055] Furthermore, a first protruding edge 11 is provided on the inner side of the lower end of the microphone body 1, and a second protruding edge 21 is provided on the outer side of the upper end of the base 2. The upper edge of the first protruding edge 11 abuts against the lower edge of the second protruding edge 21 to prevent the base 2 from detaching from the microphone body 1. In this embodiment, the inner wall of the opening of the slot 13 is provided with a first protruding edge 11, which is arranged in a circumferential manner. The second protruding edge 21 is provided on the outer wall of the upper end of the base 2, and the upper side of the second protruding edge 21 is set as a slope. When the base 2 is inserted into the slot 13, the slope of the second protruding edge 21 abuts against the first protruding edge 11 and slides relative to it. The first protruding edge 11 presses against the second protruding edge 21, thereby deforming the base 2 and inserting it into the slot 13. The lower side of the second protruding edge 21 is a stop surface. When the microphone body 1 and the base 2 move away from each other, the upper side of the first protruding edge 11 abuts against the lower side of the second protruding edge 21, thereby blocking the movement of the second protruding edge 21 and preventing the base 2 from accidentally detaching from the slot 13.

[0056] Furthermore, a limiting protrusion 12 is provided on the inner side of the lower end of the microphone body 1, and a limiting groove 22 is provided on the outer side of the base 2. The limiting protrusion 12 moves up and down along the limiting groove 22 to restrict the rotation of the base 2. The limiting protrusion 12 is located on the inner wall of the slot 13, and the extending direction of the limiting protrusion 12 is the same as the insertion and sliding direction of the base 2. The extending direction of the limiting groove 22 is consistent with the extending direction of the limiting protrusion 12, and the width of the limiting groove 22 is equal to the width of the limiting protrusion 12. The limiting protrusion 12 is inserted into the limiting groove 22, and the limiting protrusion 12 slides vertically along the limiting groove 22. When the limiting protrusion 12 is inserted into the limiting groove 22, the base 2 and the microphone body 1 are circumferentially rotated and limited, thereby preventing the base 2 from deflecting. It can be understood that the limiting protrusion 12 can also be provided on the outer wall of the base 2, and the limiting groove 22 can also be provided on the inner wall of the slot 13.

[0057] refer to Figure 11 and Figure 12 This utility model also provides a smart speaker, which includes the aforementioned liftable microphone and a speaker body 4. The speaker body 4 is provided with a storage cavity 41 for storing the liftable microphone. The speaker body 4 no longer needs a lifting and storage device inside, thereby improving the space utilization rate inside the speaker body 4 and avoiding affecting its spatial layout.

[0058] The storage cavity 41 is formed on the surface of the speaker body 4, and its structure is the same as that of the aforementioned height-adjustable microphone. The storage cavity 41 extends in a cylindrical shape, and its depth is less than the length of the height-adjustable microphone. Specifically, refer to... Figure 11 When the microphone body 1 and base 2 are in the unlocked state, the microphone body 1 and base 2 are relatively far apart. At this time, the lower end of the base 2 abuts against the bottom wall of the storage cavity 41, and the upper end of the microphone body 1 extends out of the storage cavity 41 for the user to hold and remove. (Reference) Figure 12 When the microphone body 1 and the base 2 are locked, the microphone body 1 and the base 2 are inserted close to each other. At this time, the lower end of the base 2 abuts against the bottom wall of the storage cavity 41, and the microphone body 1 is completely stored in the storage cavity 41. The upper end of the microphone body 1 does not exceed the surface of the speaker body 4, so that the speaker body 4 is kept clean after storage and the height-adjustable microphone is not bumped or worn.

[0059] In this embodiment, the bottom or side wall of the storage cavity 41 is provided with a magnetic suction device to magnetically attract the microphone after it is stored in the storage cavity 41, preventing the microphone from shaking or accidentally falling off the speaker body 4.

[0060] The speaker body 4 has a charging terminal at the bottom of the storage cavity 41 for charging the liftable microphone. This charging terminal is connected to the power supply component of the speaker body 4. The base 2 of the liftable microphone has a power receiving terminal corresponding to the charging terminal. When the liftable microphone is inserted into the storage cavity 41, the power receiving terminal and the charging terminal abut against each other to achieve an electrical connection, allowing the speaker body 4 to charge the liftable microphone. Specifically, in this embodiment, a magnetic attraction element is provided on the bottom wall of the storage cavity 41, and the liftable microphone is wirelessly charged to the speaker body 4 via a wireless connection. The charging terminal is a wireless charging transmitting coil, and the power receiving terminal is a wireless charging receiving coil.

[0061] It is understandable that the charging method for the height-adjustable microphone can also be a plug-in type. For example, the power receiving terminal is an electrical slot 13, and the charging terminal is an electrical probe. When the bottom of the base 2 abuts against the bottom wall of the storage cavity 41, the electrical probe is inserted into the electrical slot 13, so that the height-adjustable microphone and the speaker body 4 are electrically connected, and the height-adjustable microphone is charged. The charging method for the height-adjustable microphone can also be a contact type. For example, the power receiving terminal is an electrical contact, which is recessed or protruding and set at the bottom of the base 2. The charging terminal is an electrical probe. When the bottom of the base 2 abuts against the bottom wall of the storage cavity 41, the electrical probe abuts against the electrical contact and establishes an electrical connection, so that the height-adjustable microphone is charged.

[0062] Furthermore, the base 2 is also equipped with a sensing element 24 for sensing and controlling the shut-off of the liftable microphone, thereby preventing the liftable microphone from colliding or rubbing when inserted into the storage cavity 41, which could cause feedback. When the microphone is inserted into the storage cavity 41, the sensing element 24 generates a sensing signal to control the microphone to shut down. Alternatively, the sensing element 24 can also be located at the opening of the storage cavity 41. When the liftable microphone is inserted into the opening of the storage cavity 41, the liftable microphone approaches the sensing element 24 and receives the corresponding sensing signal to control the shutdown.

[0063] In some specific embodiments, the sensing element 24 is a Hall element and a magnetic element, which are respectively disposed at corresponding positions on the height-adjustable microphone and the storage cavity 41. For example, the base 2 is provided with a Hall element, and the corresponding position on the side wall or bottom wall of the storage cavity 41 is provided with a magnetic element. The trigger 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 microphone may cause feedback, and the microphone needs to be turned off. It should be noted that the sensing element 24 can also be a proximity sensor, an infrared sensor, or other electronic components.

[0064] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
