Description

An active lifting microphone and smart speaker Technical Field

[0001] This invention relates to the field of microphone technology, and more particularly to an active lift microphone and a smart speaker. Background Technology

[0002] A speaker is an electronic device that produces sound, typically used to amplify and play audio signals. With technological advancements, simple sound-playing smart speakers no longer meet user needs, leading to the emergence of smart speakers with built-in microphones for karaoke. Existing karaoke smart speakers come with a built-in microphone and feature a storage structure on the speaker itself for easy storage when not in use.

[0003] In existing smart speaker microphone storage structures, to facilitate users in removing the microphone from the smart speaker, a manual or electric lifting mechanism is usually set inside the speaker to raise and lower the microphone. However, the existing manual or electric lifting mechanism is complex in design and occupies a large amount of space in the smart speaker, affecting the internal layout and volume of the speaker. At the same time, if the lifting mechanism inside the smart speaker malfunctions or loses power, the user cannot remove the microphone, which is very inconvenient. Summary of the Invention

[0004] The main objective of this invention is to provide an active lifting microphone and a smart speaker, aiming to solve the problems of existing lifting structures for microphone storage being complex, space-consuming, and inconvenient to use.

[0005] To achieve the above objectives, the present invention proposes an active lifting microphone, comprising:

[0006] Microphone body; base, the microphone body being slidably inserted into the base; lifting device, the lifting device being disposed between the microphone body and the base, for adjusting the distance between the microphone body and the base.

[0007] To achieve the above objectives, the present invention also proposes a smart speaker, including a speaker body, wherein the speaker body has a storage slot for mounting any of the above-mentioned active lifting microphones.

[0008] The beneficial effects of this invention are as follows: This invention incorporates a lifting device between the microphone body and the base, enabling active lifting of the microphone. This solves the problems of existing microphone storage lifting structures being complex, space-consuming, and inconvenient to use. Furthermore, existing lifting devices occupy a significant amount of space within the speaker enclosure, affecting layout. When the lifting device malfunctions, the entire speaker enclosure needs to be sent for repair. The speaker enclosure is heavy, resulting in high shipping costs. This invention reduces the space occupied within the speaker enclosure, and the lifting structure is integrated inside the microphone. When the lifting structure malfunctions, only the microphone needs to be sent for repair, reducing the burden on the user. Attached Figure Description

[0071] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0072] It should be noted that if the embodiments of the present invention 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.

[0073] Furthermore, if the embodiments of this invention 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, a feature 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 invention.

[0074] Example 1:

[0075] One embodiment of the present invention provides an active lift microphone, referring to Figures 1 and 2, comprising:

[0076] Microphone body 11; base 12, the microphone body 11 is slidably inserted into the base 12; lifting device, the lifting device is set between the microphone body 11 and the base 12, and is used to adjust the distance between the microphone body 11 and the base 12.

[0077] In existing technologies, active lifting microphones are typically inserted into a storage cavity. After insertion, the top of the microphone is either below or flush with the opening of the cavity. To remove the microphone, the user needs to use a lifting device to lift it up so that its top protrudes from the cavity opening. In this embodiment, a lifting device is integrated into the active lifting microphone itself. This device actively lifts the microphone for easy removal, eliminating the need for an additional lifting device as in existing technologies. The structure is simpler, the cost is lower, and space is saved.

[0078] It should be noted that the lifting device in this embodiment can be an electrically powered lifting device. Specifically, a drive cylinder can be installed between the microphone body 11 and the base 12. The drive cylinder pushes the microphone body 11 to slide along the base 12, thereby adjusting the distance between the microphone body 11 and the base 12, realizing the active lifting and taking out of the microphone. Furthermore, a motor lead screw linear drive module of the prior art can be installed between the microphone body 11 and the base 12. The motor drives the lead screw to rotate forward or reverse, driving the nut on the lead screw to move up and down along the lead screw. After connecting the microphone body 11 to the nut, the nut can drive the microphone body 11 to rise and fall, thereby adjusting the distance between the microphone body 11 and the base 12, realizing the active lifting and taking out of the microphone.

[0079] A control element for driving the cylinder or motor to start or stop can also be integrated on the microphone body 11. Specifically, the control element can be a touch sensor in the prior art. The user presses or touches the touch sensor to make the touch sensor receive an on or off signal, and then the main control board of the active lifting microphone controls the cylinder or motor to start or stop, thereby adjusting the distance between the microphone body 11 and the base 12, so as to realize the removal and storage of the active lifting microphone.

[0080] In this embodiment, the lifting device can be manually operated. Specifically, the lifting device includes:

[0081] The reset component has two ends connected to the microphone body 11 and the base 12, respectively. The spring-loaded component is located next to the reset component and has two ends connected to the microphone body 11 and the base 12, respectively. The spring-loaded component has a locked state and an unlocked state. When the spring-loaded component is in the locked state, the microphone body 11 is fixed to the base 12. When the spring-loaded component is in the unlocked state, the microphone body 11 can slide along the base 12.

[0082] In this embodiment, the reset component adopts an elastic element 131. Through the cooperation of the reset component and the spring-lifting component, the microphone body 11 can be manually raised and lowered. The user only needs to press the spring-lifting component to switch between the locked and unlocked states of the spring-lifting component. Thus, under the elastic force of the elastic element 131, the microphone body 11 is driven to lift and lower, completing the removal and storage of the actively raised and lowered microphone.

[0083] Specifically, after the active lifting microphone is stored in the storage cavity, as shown in Figure 1, the active lifting microphone is in its initial state, the spring-loaded component is locked, the microphone body 11 is not raised, and the microphone body 11 is fixed to the base 12. When it is necessary to remove the active lifting microphone, the user presses the top of the microphone body 11 (the end of the microphone body 11 away from the base 12), the spring-loaded component is unlocked, changing from the locked state to the unlocked state. Referring to Figure 2, the microphone body 11 slides towards the end away from the base 12, the active lifting microphone rises as a whole, and the top of the active lifting microphone extends beyond the opening of the storage cavity, thus facilitating the user to remove the active lifting microphone. It should be noted that the unfolded length of the active lifting microphone in Figure 2 is only an example, and its unfolded length can be adjusted according to actual needs.

[0084] Referring to Figures 3 and 4, the lifting assembly includes: a locking device 132, rotatably mounted on the microphone body 11; and a guide groove 133, formed on the base 12 along the lifting direction of the active lifting microphone. The locking device 132 and the guide groove 133 are slidably connected. The locking device 132 and the guide groove 133 have a locked state and an unlocked state. When the locking device 132 and the guide groove 133 are in the locked state, the microphone body 11 is fixed to the base 12. When the locking device 132 and the guide groove 133 are in the unlocked state, the microphone body 11 can slide along the base 12.

[0085] In this embodiment, the structure of elastic element 131, fastener 132 and guide groove 133 can realize the switching between locked and unlocked states of the lifting component. The structure is simple, easy to operate, and occupies little space. It can avoid the excessive size of the active lifting microphone. At the same time, it avoids the problem of failure to lift normally due to circuit failure when using electric lifting in the prior art, thus ensuring the stability of lifting.

[0086] After the active lifting microphone is stored in the storage cavity, as shown in Figure 1, the active lifting microphone is in its initial state. The locking fastener 132 is locked to the guide groove 133, the microphone body 11 is not raised, the elastic element 131 is compressed, and the microphone body 11 is fixed to the base 12. When it is necessary to remove the active lifting microphone, the user presses the top of the microphone body 11 (the end of the microphone body 11 away from the base 12). At this time, the locking fastener 132 will slide and rotate in the guide groove 133, thereby unlocking the locking fastener 132 and the guide groove 133, changing from the locked state to the unlocked state. At this time, the elastic restoring force of the elastic element 131 will be applied between the microphone body 11 and the base 12. Thus, the microphone body 11 receives the elastic force of the elastic element 131. Referring to Figure 2, the microphone body 11 slides towards the end away from the base 12. During this process, the locking fastener 132 will slide along the guide groove 133, and the active lifting microphone will be raised as a whole. The top of the active lifting microphone will exceed the opening of the storage cavity, making it convenient for the user to remove the active lifting microphone. Compared with existing lifting devices, the lifting component in this embodiment has a simpler structural design. The locking and unlocking states of the lifting component can be switched by sliding and rotating the fastener 132 in the guide groove 133. The user only needs to press the end of the microphone body 11. The operation is very simple, and the cost is lower, the space occupancy is small, and it is easy to integrate into an active lifting microphone.

[0087] Referring to Figure 6, the guide groove 133 includes a first groove 1331 and a second groove 1332. When the fastener 132 is located in the first groove 1331, the fastener 132 can rotate within the first groove 1331 to achieve state switching between the fastener 132 and the guide groove 133. When the fastener 132 is located in the second groove 1332, the fastener 132 can slide within the second groove 1332 to achieve sliding of the microphone body 11 along the base 12.

[0088] In this embodiment, the first groove 1331 and the second groove 1332 are distributed along the sliding direction of the microphone body 11. In the sliding direction of the microphone body 11, the first groove 1331 is located below the second groove 1332. The locking member 132 can slide within the second groove 1332 and slide and rotate within the first groove 1331. Specifically, in the initial state, when the locking member 132 is not locked to the guide groove 133, the microphone body 11 and the base 12 are subjected to the elastic force at both ends of the elastic member 131. The microphone body 11 will move towards the end away from the base 12, thereby the locking member 132 will slide to the top of the second groove 1332. When the user presses down on the microphone body 11, the microphone body 11 slides towards the base 12, and the locking member 132 will slide along the second groove... Part 1332 slides into the first groove 1331. After the locking device 132 enters the first groove 1331, it will rotate to lock the locking device 132 with the guide groove 133. At this time, the elastic element 131 is compressed. When unlocking is required, the user presses the end of the microphone body 11 again, causing the locking device 132 to continue to rotate in the first groove 1331, thereby unlocking the locking device 132 with the guide groove 133. After the locking device 132 and the guide groove 133 are unlocked, the elastic restoring force of the elastic element 131 lifts the microphone body 11. The locking device 132 slides from the first groove 1331 into the second groove 1332 and returns to the initial position at the top of the second groove 1332, completing the lifting of the microphone body 11, making it convenient for the user to take out the active lifting microphone.

[0089] Referring to Figure 5, the first end of the fastener 132 is rotatably connected to the microphone body 11, and the second end of the fastener 132 is provided with a first abutment 1321, a second abutment 1322, a third abutment 1323 and a fourth abutment 1324 in sequence along its rotation direction.

[0090] A first abutting surface 1325 is formed between the first abutting portion 1321 and the second abutting portion 1322, and a second abutting surface 1326 is formed between the third abutting portion 1323 and the fourth abutting portion 1324. The first abutting surface 1325 and the second abutting surface 1326 are parallel.

[0091] Referring to Figure 6, the first groove 1331 includes a first sidewall 13311, a second sidewall 13312, a third sidewall 13313, a fourth sidewall 13314, a fifth sidewall 13315, a sixth sidewall 13316, and a seventh sidewall 13317. A first corner 13318 is formed between the second sidewall 13312 and the third sidewall 13313, and a second corner 13319 is formed between the sixth sidewall 13316 and the seventh sidewall 13317. When the fastener 132 and the guide groove 133 are locked, the first abutting part 1321 abuts against the seventh sidewall 13317, the second abutting part 1322 abuts against the first sidewall 13311, and the fourth abutting part 1324 abuts against the fifth sidewall 13315.

[0092] In this embodiment, the contact portion and contact surface of the fastener 132 abut against the sidewalls and corners of the first groove 1331 and the second groove 1332 to achieve sliding and rotation of the fastener 132, thereby completing the locking and unlocking between the fastener 132 and the guide groove 133. Specifically, referring to Figures 7 to 17, the movement process between the fastener 132 and the guide groove 133 and the switching between the unlocking and locking states are described in detail.

[0093] Referring to Figure 7, the fastener 132 and the guide groove 133 are not locked. Under the elastic force of the elastic member 131, the fastener 132 rises to the first end away from the base 12. The fastener 132 is located at the top of the second groove 1332. At this time, the active lifting microphone is stored in the storage cavity, and the top of the active lifting microphone extends beyond the opening of the storage cavity. The active lifting microphone is not fully stored.

[0094] When the active lifting microphone needs to be fully stored in the storage cavity, the microphone body 11 needs to be fully pressed into the storage cavity. At this time, the user needs to press the end of the microphone body 11. During this process, referring to Figure 8, the active lifting microphone will slide down along the second groove 1332 into the first groove 1331. During the downward sliding of the microphone body 11, the elastic element 131 will be compressed. Referring to Figures 9 and 10, when the active lifting microphone slides at the junction of the first groove 1331 and the second groove 1332, the first abutting surface 1325 formed between the first abutting part 1321 and the second abutting part 1322 abuts against the second corner 13319, thereby driving the locking device 132 to rotate counterclockwise during the process of the locking device 132 sliding from the second groove 1332 to the first groove 1331. Referring to Figure 11, when the locking device 132 moves to the bottom of the first groove 1331, its second abutment surface 1326 abuts against the first corner 13318. At this time, the locking device 132 can no longer move downwards. The user's hand, which is used to press down the microphone body 11, feels the counter-pushing force and receives the signal that the microphone body 11 has been pressed down to the end, and then releases the hand. After the user releases the hand, the microphone body 11 will rise under the elastic restoring force of the elastic element 131. Since the second abutment surface 1326 abuts against the first corner 13318 and the fourth abutment part 1324 abuts against the fourth side wall 13314, the locking device 132 will continue to rotate counterclockwise during the rising process, as shown in Figure 12.

[0095] Referring to Figure 13, when the locking device 132 rises again to the junction of the first groove 1331 and the second groove 1332, the second abutting part 1322 abuts against the first side wall 13311, and the groove formed between the first abutting part 1321 and the fourth abutting part 1324 is stuck at the second corner 13319. At this time, the locking device 132 is stuck there and cannot rise. The locking device 132 and the guide groove 133 are locked together and in a locked state. The active lifting microphone is completely stored in the storage slot 42, completing the storage of the active lifting microphone.

[0096] When the active lifting microphone needs to be removed, i.e., the microphone body 11 rises out of the opening of the storage cavity, the user needs to press the end of the microphone body 11 again. The locking member 132 slides downward toward the first groove 1331. At this time, the elastic member 131 is compressed again. Referring to Figure 13, at the moment the locking member 132 slides downward, the second abutment 1322 separates from the first side wall 13311, and the seventh side wall 13317 provides abutment force to the first abutment 1321, thereby driving the locking member 132 to continue to rotate counterclockwise during the downward movement. Referring to Figures 14 and 15, when the locking member 132 slides down to the bottom of the first groove 1331 again, the second abutment 1322 abuts against the second side wall 13312, and the locking member 132 can no longer descend. The user's hand receives a counter-pushing force and receives a signal that the microphone body 11 has been pressed into place, and then releases the hand. After the user releases their hand, the microphone body 11 will rise and rotate counterclockwise under the elastic restoring force of the elastic element 131. Referring to Figure 16, the second abutment part 1322 abuts against the second side wall 13312, and the first abutment surface 1325 and the second abutment surface 1326 of the locking fastener 132 both extend along the sliding direction of the microphone body 11, and the locking fastener 132 is opposite to the opening of the second groove 1332. At this time, the locking fastener 132 will continue to rise under the elastic restoring force of the elastic element 131, rising from the first groove 1331 to the top of the second groove 1332, and returning to the initial position, as shown in Figure 17. At this time, the microphone body 11 is lifted up, and its end extends beyond the opening of the storage cavity, making it convenient for the user to take out the active lifting microphone.

[0097] The elastic element 131 is configured as a spring, with its first end mounted on the base 12. The microphone body 11 has a positioning groove 111 for inserting the second end of the spring. It should be noted that the elastic element 131 can be made of a material with elastic stretching properties, as is available in the prior art, or it can be made of a structure with a telescopic function, depending on the internal space of the actual active lifting microphone. In this embodiment, the elastic element 131 is configured as a spring, which is a standard component in the prior art, offering a wide range of selectable elastic properties, low cost, and easy installation. During use, one end can be fixed inside the base 12, for example, by adhesive or snap-fit, making the spring and base 12 a single unit. A corresponding positioning groove 111 is provided on the microphone body 11. After the microphone body 11 is inserted into the base 12, the other end of the spring is inserted into the corresponding positioning groove 111, so that both ends of the spring abut against the microphone body 11 and the base 12 respectively, facilitating the lifting and lowering movement of the microphone body 11.

[0098] Referring to Figures 3 and 4, the base 12 is provided with at least one limiting post 121 along the lifting direction of the active lifting microphone, and the microphone body 11 is provided with limiting slots 112 that are respectively inserted into the limiting post 121. When the microphone body 11 and the base 12 are connected, the limiting post 121 and the limiting slot 112 can be inserted into each other, thereby effectively positioning the microphone body 11 and the base 12 for installation, facilitating the installation of the two. At the same time, the limiting post 121 and the limiting slot 112 can effectively support and guide the lifting movement of the microphone body 11, ensuring the stability of the microphone body 11 during the lifting process. Specifically, in this embodiment, two limiting posts 121 and two limiting slots 112 are respectively provided, and the two limiting posts 121 and the two limiting slots 112 are symmetrically arranged on the cross-sections of the base 12 and the microphone body 11, which can ensure the stability of the force and further improve the stability of the microphone body 11 during the lifting process.

[0099] The base 12 has a first protruding edge 122 along its edge at one end, and the microphone body 11 has a second protruding edge 113 that engages with the first protruding edge 122 at one end. After the microphone body 11 is inserted into the base 12, the first protruding edge 122 and the second protruding edge 113 are engaged and fixed, which can limit the sliding of the microphone body 11 and prevent the microphone body 11 from becoming loose from the base 12. In this embodiment, the first protruding edge 122 and the second protruding edge 113 are arranged in a ring around the outer periphery of the base 12 and the microphone body 11, respectively. The outer edge of the first protruding edge 122 or the second protruding edge 113 can be chamfered to provide a certain guidance during the engagement process, so as to facilitate the engagement of the first protruding edge 122 and the second protruding edge 113 together.

[0100] Example 2:

[0101] As shown in Figures 18-26, an active lifting microphone differs from Embodiment 1 in that the lifting device 4 includes a rotary drive 41, the drive end of the rotary drive 41 is connected to a rotating disk 42, and the rotating disk 42 is connected to the transmission component 2 to drive the transmission component 2 to move up and down.

[0102] Referring to Figures 18 to 20, when the rotary drive 41 is activated, the rotary drive 41 drives the rotating disk 42 to rotate, the rotating disk 42 drives the transmission gear 43 to rotate, and the transmission gear 43 meshes with the transmission groove 21 of the transmission component 2, thereby driving the transmission component 2 to rise and fall in the vertical direction through the meshing action with the transmission groove 21, thereby realizing the automatic raising and lowering of the microphone body 1.

[0103] Referring to Figures 20 to 22, the transmission component 2 is provided with two sets of transmission grooves 21 arranged in parallel, and both sets of transmission grooves 21 are arranged along the lifting direction of the transmission component 2.

[0104] The rotation center of the rotating disk 42 is located on the center line between the two sets of transmission grooves 21. The rotating disk 42 is provided with a number of transmission teeth 43 that mesh with the transmission grooves 21 along its circumference. The number of transmission teeth 43 mesh with only one set of transmission grooves 21 in any rotation state.

[0105] In existing smart speaker microphone storage structures, transmission mechanisms often employ complex gear, chain, or lead screw transmission methods. However, these methods are complex, have high maintenance costs, and are prone to vibration and noise during use. Therefore, in this embodiment, a transmission groove 21 and transmission teeth 43 structure are used, which greatly simplifies the transmission structure and reduces costs while ensuring transmission stability. Specifically, when the rotary drive 41 starts and drives the rotating disk 42 to rotate, the transmission teeth 43 move along the transmission groove 21 that meshes with it, thereby driving the transmission component 2 to complete the lifting and lowering motion, realizing the lifting and lowering of the microphone body 1. It should be noted that this embodiment adopts a double transmission groove 21 structure design, ensuring the stability and balance of the transmission. The rotation center of the rotating disk 42 is precisely located on the center line between the two transmission grooves 21, ensuring that the rotating disk 42 can engage with the transmission grooves 21 evenly and smoothly during rotation. When the rotating disk 42 rotates, at any given time only one set of transmission teeth 43 is engaged with one set of transmission grooves 21, while the other set of transmission grooves 21 is in an unoccupied state. This design achieves continuous transmission through alternating engagement, avoiding movement jamming. The entire process of the rotary drive component 41 only requires rotation in the same direction to complete the lifting and lowering drive of the transmission component 2, without the need for forward and reverse rotation, which can simplify the design of the drive circuit and reduce costs.

[0106] The transmission component 2 has a rectangular slot 22, and two sets of transmission slots 21 are respectively arranged on one set of symmetrical sides of the rectangular slot 22. By creating the rectangular slot 22 on the transmission component 2, the overall weight is reduced, and the strength of the transmission component 2 is enhanced through reasonable structural design, making the microphone more stable during lifting and lowering, while also reducing energy consumption. The two sets of symmetrical sides of the rectangular slot 22 serve as the mounting positions for the transmission slots 21, which not only facilitates processing and installation, but also optimizes the transmission path, reduces friction and loss during transmission, and improves transmission efficiency. The overall transmission structure is more compact and has a high space utilization rate.

[0107] The transmission process between transmission component 2 and rotating disk 42 is explained in detail in Figures 23-26.

[0108] It should be noted that the figure shows the relative positions of the transmission component 2 and the rotating disk 42. In actual transmission, the position of the rotating disk 42 remains fixed, while the transmission component 2 moves up and down. Specifically, in the initial state, the rotating disk 42 is located at the top of the rectangular slot 22, and the transmission component 2 is at its lowest point. At this time, the transmission gear 43 engages with the transmission groove 21 on the left. When the microphone needs to be removed, the microphone body 1 needs to be driven to rise, that is, the transmission component 2 needs to be driven to rise. At this time, the rotation drive component 41 drives the rotating disk 42 to rotate clockwise. As the rotating disk 42 rotates, the transmission gear 43 engages with the transmission groove 21, thereby lifting the transmission component 2. Referring to Figure 24, this is the state diagram of the transmission component 2 during the lifting process. After the transmission gear 43 separates from the transmission groove 21 on the left, it engages with the transmission groove 21 on the right. At this time, referring to Figure 25, the rotating disk 42 is located at the bottom of the rectangular slot 22, the transmission component 2 is at its highest point, and the microphone body 1 is also raised to its highest point, making it convenient for the user to remove the microphone. When the microphone body 1 needs to be retracted, the rotary drive 41 continues to rotate, driving the rotating disk 42 to continue rotating, and the transmission gear 43 rotates further, pressing the transmission component 2 down and retracting it. Referring to Figure 26, this is a state diagram of the transmission component 2 during its descent. Finally, when the rotating disk 42 is at the top of the rectangular slot 22, that is, when the transmission component 2 is at its lowest point, it returns to its initial position, as shown in Figure 23. At this point, the retraction action of the microphone body 1 is completed.

[0109] The principle of the outer shell 11 and the base 3 in this embodiment is the same as that in embodiment 1. Referring to Figures 19 and 20, the microphone body 1 includes an outer shell 11, the transmission component 2 is installed inside the outer shell 11, the outer shell 11 is slidably inserted into the base 3, the outer periphery of the end of the base 3 is provided with a first protruding edge 31, and the end of the outer shell 11 is provided with a second protruding edge 12 that abuts against the first protruding edge 31.

[0110] The base 3 is also equipped with a lifting guide assembly, and the transmission component 2 is connected to the lifting guide assembly. In this embodiment, by adding a lifting guide assembly inside the base 3, the lifting of the microphone body 1 can be effectively guided, ensuring the stability and smoothness of the lifting process.

[0111] Specifically, the lifting guide assembly includes two parallel guide rails 5. Each guide rail 5 includes a fixed part 51 and a sliding part 52. The fixed part 51 is connected to the base 3, and the sliding part 52 is connected to the transmission component 2. In this embodiment, by designing parallel guide rails 5 as the lifting guide assembly, the stability and accuracy of the transmission component 2 during the lifting process are further improved, noise and vibration are reduced, and the fixed part 51 and sliding part 52 of the guide rails 5 have stronger structural stability and can withstand the force generated by the transmission component 2 during the lifting process, thereby enhancing the overall structural strength and making the microphone more stable and reliable during long-term use.

[0112] The rotary drive component 41 is configured as a drive motor. In this embodiment, using a drive motor as the rotary drive component 41 enables faster and smoother lifting movements. Compared to traditional manual or mechanical lifting methods, the drive motor offers higher efficiency and more stable performance. By equipping it with a corresponding control system, such as a motor controller and position sensors, precise control of the microphone body 1's lifting position can be achieved.

[0113] A sensing module 13 is provided on the side of the microphone body 1 away from the base 3. The sensing module 13 is used to detect contact signals so that the rotary drive 41 drives the transmission component 2 to move up and down when it receives a contact signal.

[0114] Specifically, in this embodiment, the sensing module 13 can be configured as two, including a pressure sensor and an infrared temperature sensor. Both sensors are connected to the microphone's control chip. When an object is detected pressing / touching the top of the microphone, the pressure sensor sends a signal to the control chip. When the temperature of the object touching / pressing the microphone is within the human body temperature range, the infrared temperature sensor sends a signal to the control chip. It should be noted that, to avoid accidental microphone lifting, in this embodiment, the control chip only determines that a user's hand is touching the microphone when it simultaneously receives signals from both the pressure sensor and the infrared temperature sensor. This triggers a drive command to the rotation drive 41, controlling the microphone body 1 to lift.

[0115] Example 3:

[0116] As shown in Figures 27-34, an active lifting microphone differs from Embodiment 1 in that 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 separated. The fixing member 31 is located at the bottom of the microphone body 1, and the hook member 32 is located on the base 2. The hook member 32 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 locked.

[0117] This design incorporates a lifting device 3 inside the microphone, enabling the microphone to actively rise and fall, thus avoiding the impact on the internal space layout of the speaker enclosure caused by installing the lifting device 3 inside the enclosure. Furthermore, the actively lifting microphone in this design facilitates storage and retrieval. When the microphone is inserted into the speaker enclosure for storage, the microphone body 1 moves closer to the base 2, and the fixing member 31 engages with the hook member 32 to lock the microphone in place. When removing the microphone, pressing the microphone body 1 again unlocks the fixing member 31 and the hook member 32, and the reset member 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 slides into the slot 13, thereby enabling relative lifting and falling movement between the base 2 and the microphone body 1. The outer wall of the base 2 slides against the groove wall of the slot 13, preventing the base 2 and the microphone body 1 from wobbling relative to each other.

[0118] 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.

[0119] Referring to Figures 31 and 32, 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 to each other. The two ends of the reset element 33 abut against the first limiting groove 131 and the second limiting groove 23, respectively, 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.

[0120] Referring to Figures 28 and 29, the latch 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.

[0121] 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.

[0122] Referring to Figure 30, the fixing member 31 has a horizontally open fixing groove 311, and the front end of the hook 3231 is provided with a roller. When the microphone body 1 is subjected to force and moves downward, the roller rolls at the bottom of the fixing member 31 and is engaged in the fixing groove 311 through the opening. The roller at the front end of the hook 3231 can rotate, thereby allowing the roller to roll and slide into the fixing groove 311 along the 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.

[0123] 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. 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.

[0124] Referring to Figures 32 and 34, the 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.

[0125] 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. 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 swing 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. The guide block 3222 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.

[0126] 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.

[0127] The swing member 323 has a first rotating shaft 3233 and a first driving member 3234 disposed 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 to 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.

[0128] The hook component 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. 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 the 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.

[0129] In this embodiment, the principle of the outer shell and the base 2 engaging is the same as in embodiment 1. The inner wall of the slot 13 opening is provided with a second protruding edge 11, which is arranged in a circumferential manner. A first protruding edge 21 is located on the upper outer wall of the base 2, and its upper side is a slope. The lower side of the first protruding edge 21 serves as a stop. When the microphone body 1 and the base 2 move away from each other, the upper side of the second protruding edge 11 abuts against the lower side of the first protruding edge 21, thereby preventing the second protruding edge 11 from moving and thus preventing the base 2 from accidentally disengaging from the slot 13.

[0130] 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 limited to prevent 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.

[0131] Example 4:

[0132] As shown in Figures 35-37, an active lifting microphone differs from Embodiment 1 in that the lifting device includes a reset component 1, a hook component 2, and a locking block 3. The locking block 3 is disposed on the base 200. The side of the locking block 3 facing the microphone body 100 has an inclined surface 31, and the side of the locking block 3 away from the inclined surface 31 has a locking groove 32. One end of the hook component 2 slides on the inclined surface 31 and engages with the locking groove 32. The hook component 2 disengages from the locking groove 32 when the reset component 1 is in its natural state. The above design adopts an overall hidden structure layout, with mechanical locking to prevent accidental contact and no need for external tools or power supply, taking into account operational safety, compact space, and simple appearance.

[0133] Please refer to Figure 35. The hook assembly 2 includes a mounting block 21 and a swing rod 22. One end of the swing rod 22 is rotatably connected to the mounting block 21 via a torsion spring 23, and the other end of the swing rod 22 is provided with a hook shaft 221 that engages with the locking groove 32. In this embodiment, the hook assembly 2 also includes a connecting shaft 24. The mounting block 21 is provided with two shaft holes for the connecting shaft 24 to be inserted. The connecting shaft 24 passes through one shaft hole, then through the swing rod 22, and finally is inserted into the other shaft hole. The torsion spring 23 is provided on the connecting shaft 24 and is located between the swing rod 22 and the shaft hole. One end of the torsion spring 23 is inserted into the side of the swing rod 22. The above arrangement allows the swing rod 22 to swing, thereby allowing the hook shaft 221 on the swing rod 22 to engage with the locking groove 32. Furthermore, this design also allows the hook shaft 221 on the swing rod 22 to disengage from the locking groove 32, and under the action of the torsion spring 23, the hook shaft 221 on the swing rod 22 returns to its initial position.

[0134] In this embodiment, please refer to Figures 35 and 36. The lifting device also includes a guide assembly 4, which is installed inside the base 200. The guide assembly 4 is provided with a guide cavity 41, the opening of which is located below the swing arm 22. The side of the locking block 3 is fixed to or integrally formed with the inner wall of the guide cavity 41. Correspondingly, the end of the swing arm 22 away from the mounting block 21 is provided with an arrow-shaped guide block 222. The bottom of the guide cavity 41 is provided with a guide folding surface 411 that moves in conjunction with the guide block 222. The guide cavity 41 is provided to limit the active position of the swing arm 22 and prevent the swing arm 22 from swinging too much, which would affect the engagement or disengagement of the hook shaft 221 from the locking groove 32. Furthermore, through the cooperation of the guide block 222 and the guide folding surface 411, the vertical movement distance of the swing arm 22 is limited, and the sliding of the guide block 222 on the guide folding surface 411 facilitates the disengagement of the hook shaft 221 from the locking groove 32.

[0135] In order to facilitate the accurate and rapid entry of the swing arm 22 into the guide cavity 41, in this embodiment, the inner wall of the opening end of the guide cavity 41 is provided with a flat angle 412.

[0136] In this embodiment, please refer to Figure 35. The reset component 1 includes a reset spring 11. One end of the reset spring 11 is elastically connected to the mounting block 21, and the other end is elastically connected to the guide component 4. This setting mainly allows the mounting block 21 to be raised and lowered, thereby raising and lowering the microphone body 100. Specifically, when the user presses the microphone body 100, the microphone body 100 is inserted into the base 200, and the bottom of the microphone body 100 presses against the mounting block 21, causing the reset spring 11 to be compressed. This causes the hook shaft 221 on the swing arm 22 to engage with the locking groove 32. At this time, the deformation generated by the reset spring 11 becomes stable. When the user presses down the microphone body 100 again, the reset spring 11 returns to its original deformation, providing a thrust for the microphone body 100 to disengage from the base 200, causing the microphone body 100 to rise, so that the user can hold the microphone body 100.

[0137] Please refer to Figures 36 and 37. The fit between the microphone body 100 and the base 200 is the same as in Embodiment 3. The connection is achieved by a plurality of second protruding edges 101 on the inner wall of the microphone body 100 facing the base 200, and a first protruding edge 201 on the outer side of the base 200 that engages with the second protruding edges 101. To limit the sliding range of the second protruding edges 101, an annular limiting protrusion 203 is provided on the outer side of the base 200 away from the microphone. A plurality of vertically oriented limiting posts 102 are provided on the inner wall of the microphone body 100 facing the base 200, and grooves 202 on the outer side of the base 200 that engage with the corresponding limiting posts 102, restricting the rotational movement of the microphone body 100.

[0138] In this embodiment, the mounting block 21 also has a power supply function. For example, the top of the mounting block 21 is provided with a socket, and the bottom of the microphone is provided with a plug that is connected to the socket. When the microphone body 100 is connected to the base 200, the microphone body 100 can be charged accordingly. Of course, in other embodiments, the mounting block 21 can be a wireless charger, or a charging device with a probe on the top surface, etc.

[0139] Example 5:

[0140] As shown in Figures 38-47, an active lifting microphone differs from Embodiment 1 in that the lifting device 3 includes a fixing member 31, a locking component 32, and a resetting member 33. The fixing member 31 is fixed to the microphone body 1, and the locking component 32 is fixed to the base 2. The locking component 32 includes a locked state and an unlocked state. When the microphone body 1 moves downward, it pushes the locking component 32 to clamp the fixing member 31. When the locking component 32 reaches the locked state, the microphone body 1 continues to move downward to push the locking component 32 to switch to the unlocked state. The resetting member 33 drives the fixing member 31 to separate from the locking component 32, causing the microphone body 1 to spring upward and reset.

[0141] In this design, the microphone body 1 is slidably inserted into the base 2. The locking component 32 and the fixing member 31 are respectively fixed to the base 2 and the microphone body 1. By pressing down the microphone body 1, the locking component 32 clamps the fixing member 31 and locks it in place, preventing the microphone body 1 from sliding upward relative to the base 2, thus allowing the microphone to be stored inside the speaker. When the microphone is removed, pressing the microphone body 1 again switches the locking component 32 to the unlocked state. Under the push of the reset component 33, the locking component 32 separates from the fixing member 31, and the microphone body 1 pops upward.

[0142] Specifically, the bottom of the microphone body 1 is provided with a slot 13, which allows the base 2 to slide into the slot 13, thereby allowing the base 2 to rise and fall relative to the microphone body 1. The diameter of the base 2 is equal to the diameter of the slot 13, so that the outer wall of the base 2 fits against the inner wall of the slot 13 to prevent the base 2 from wobbling left and right relative to the microphone body 1.

[0143] The fixing component 31 is integrally fixed to the bottom wall of the slot 13, and the locking component 32 is fixed to the base 2. It is understood that the positions of the fixing component 31 and the locking component 32 can be interchanged. When the active lifting microphone is retracted into the speaker enclosure, the user presses the microphone body 1 downwards, bringing the microphone body 1 and base 2 closer together. The locking component 32 abuts against the fixing component 31, thus clamping and fixing the fixing component 31. At this time, the locking component 32 is in a locked state, preventing the fixing component 31 from disengaging and the microphone body 1 from popping upwards. The active lifting microphone is completely retracted into the speaker enclosure. When it is necessary to remove the microphone, the user presses the microphone body 1 downwards again, causing the fixing component 31 to push the locking component 32 downwards, switching the locking component 32 to the unlocked state. The locking component 32 releases its restriction on the fixing component 31. Driven by the reset component 33, the microphone body 1 moves upwards, allowing the upper end of the microphone body 1 to extend beyond the surface of the speaker enclosure, making it convenient for the user to grasp and remove the active lifting microphone.

[0144] In this embodiment, the reset member 33 is a spring, with its two ends abutting against the bottom walls of the base 2 and the slot 13, respectively. When the microphone body 1 and the base 2 approach each other, the reset member 33 accumulates a spring force that separates them. When the locking component 32 releases its restriction on the fixing member 31, the reset member 33 releases the spring force, allowing the microphone body 1 and the base 2 to separate relative to each other. Alternatively, the reset member 33 can also be two magnets with repulsive like poles, each mounted on the bottom wall of the slot 13 and the base 2, respectively, to generate a magnetic force that separates them.

[0145] The locking assembly 32 includes a housing 321, a locking member 322, and a swing hook 323. The housing 321 has a lifting channel 3211. The locking member 322 slides along the lifting channel 3211 and is used to clamp and fix the fixing member 31. One end of the swing hook 323 is rotatably connected to the locking member 322, and the other end of the swing hook 323 is set as a hook portion 3231 and locks or unlocks with the housing 321. The housing 321 is fixedly connected to the base 2. The lifting channel 3211 extends along the lifting direction of the microphone body 1. The locking member 322 is disposed in the lifting channel 3211 and slides along the extending direction of the lifting channel 3211. The swing hook 323 is rotatably connected to the locking member 322 and moves up and down along the locking member 322. The hook portion 3231 locks and unlocks the locking member 322 by engaging or disengaging with the housing 321. When the microphone body 1 is pressed down, the fixing member 31 pushes the locking member 322 downward, and the locking member 322 simultaneously clamps the fixing member 31. The hook 3231 engages with the housing 321, causing the locking component 32 to enter the locked state. When the microphone body 1 continues to be pressed down, the hook 3231 of the swing hook 323 disengages from the housing 321, and the locking component 32 switches to the unlocked state.

[0146] The locking member 322 has two grippers 3221 at its end. These grippers 3221 elastically open and are used to clamp or release the fixing member 31. Two opposing grippers 3221 are located near the fixing member 31 at one end of the locking member 322. The distance between the two grippers 3221 when naturally open is greater than the opening width of the lifting channel 3211. The grippers 3221 clamp the fixing member 31 and retract into the lifting channel 3211, thereby reducing the distance between the two grippers 3221 and increasing the clamping force on the fixing member 31 to prevent the fixing member 31 from disengaging from the locking member 322. In this embodiment, the two grippers 3221 are integrally connected to the upper end of the locking member 322, and the grippers 3221 at the connection point are arc-shaped, thus providing a left-right swinging restoring force to the suspended end of the grippers 3221. The two grippers 3221 are tilted and open in their natural state. When the fixing member 31 moves downward and abuts against the upper end of the locking member 322, the two grippers 3221 are located on both sides of the fixing member 31. When the fixing member 31 continues to push the locking member 322 downward, the two grippers 3221 move downward synchronously. The suspended ends of the two grippers 3221 are squeezed closer together by the side wall of the lifting channel 3211, thereby clamping and fixing the fixing member 31. At the same time, the swing hook 323 descends synchronously with the locking member 322. The hook part 3231 of the swing hook 323 swings to engage with the housing 321, so that the locking member 322 reaches the locked state and cannot spring upward to reset. The two grippers 3221 clamp and fix the fixing member 31. When the locking member 322 switches to the unlocked state, the locking member 322 springs upward, and the two grippers 3221 slide out of the lifting channel 3211 and open relative to each other, thereby releasing their limitation on the fixing member 31. It should be noted that in this embodiment, the width of the lifting channel 3211 gradually decreases from top to bottom, and the inner wall of the lifting channel 3211 extends obliquely, so that the clamping force of the two claws 3221 gradually increases as the locking member 322 gradually descends, preventing the fixing member 31 from accidentally disengaging.

[0147] The fixing member 31 is a cylindrical structure, and its end is provided with a protrusion 311 for clamping by the grippers 3221. In this embodiment, one end of the fixing member 31 is fixed to the bottom of the slot 13, and the end of the fixing member 31 near the locking member 322 is provided with a protrusion 311. There are two protrusions 311, which extend from the two sides of the end of the fixing member 31 to be clamped by the grippers 3221 on both sides of the fixing member 31. Specifically, the protrusions 311 extend obliquely, and the width of the protrusions 311 gradually increases in the direction from bottom to top along the fixing member 31, so that the fixing member 31 is not blocked when it is inserted into the middle of the two grippers 3221, and when the two grippers 3221 come together to clamp, the grippers 3221 can clamp the upper end face of the protrusions 311 to improve the firmness.

[0148] In this embodiment, in order to improve the stability of the clamping member 31 by the jaws 3221 and prevent the clamping member 31 from accidentally slipping out from the middle of the jaws 3221, the suspended end of the jaws 3221 is hook-shaped. That is, when the clamping member 31 is inserted between the two jaws 3221, the two jaws 3221 are relatively close, and the hook-shaped structure of the jaws 3221 engages with the upper end face of the protrusion 311, thereby restricting the clamping member 31 by the hook-shaped structure on the jaws 3221, and further improving the clamping stability.

[0149] The locking assembly 32 also includes a torsion spring 324 connected to the swing hook 323, which drives the swing hook 323 to deflect. One torsion arm of the torsion spring 324 is fixed to the locking member 322, and the other torsion arm is fixed to the swing hook 323. The torsion spring 324 provides a restoring force to the swing hook 323, thereby resetting the swing hook 323 after swinging, so as to facilitate the next swing of the swing hook 323. Specifically, as the swing hook 323 moves downward with the locking member 322, the hook part 3231 is squeezed and swings, causing the hook part 3231 to engage with the housing 321. The torsion spring 324 accumulates torsional elasticity. When the microphone body 1 is pressed again, the hook part 3231 disengages from the housing 321, and the swing hook 323 swings back to reset under the drive of the torsion spring 324.

[0150] The housing 321 has a guide block 3212 on the inner wall of the lifting channel 3211. The guide block 3212 includes a locking groove 3212a, a first inclined surface 3212b, and a second inclined surface 3212c. When the microphone body 1 moves downward, the hook 3231 slides along the first inclined surface 3212b and engages with the locking groove 3212a, locking the swing hook 323 with the housing 321. As the microphone body 1 continues to move downward, the torsion spring 324 drives the hook 3231 to swing out of the locking groove 3212a, unlocking the swing hook 323 from the housing 321. The hook 3231 then slides back to its original position along the second inclined surface 3212c. The guide block 3212 is positioned on the path of the swing hook 323's vertical movement and has an oblique, triangular-like structure. In this embodiment, the first inclined surface 3212b is located on the left side of the guide block 3212, the second inclined surface 3212c is located on the right side of the guide block 3212, and the locking groove 3212a is located at the end of the guide block 3212 away from the locking block. Both the first inclined surface 3212b and the second inclined surface 3212c are inclined to the right, and the inclination angle of the first inclined surface 3212b is greater than the inclination angle of the second inclined surface 3212c, so that the length of the first inclined surface 3212b is greater than the length of the second inclined surface 3212c.

[0151] In the initial state, the swing hook 323 deflects to the right under the deflection force of the torsion spring 324, causing the hook 3231 to point to the right of the center of the guide block 3212, and the hook 3231 is located to the right of the locking groove 3212a. When the microphone body 1 is pressed down, the locking member 322 is pushed down by the fixing member 31, and the two grippers 3221 clamp and fix the fixing member 31. The swing hook 323 moves vertically in sync, causing the hook 3231 to abut against the first inclined surface 3212b and slide down along the first inclined surface 3212b. During the sliding process of the hook 3231, the hook 3231 is pushed by the first inclined surface 3212b, causing the swing hook 323 to gradually deflect to the left, and the torsion spring 324 generates the opposite torque force. As the locking member 322 moves downward, the hook 3231 slides to the lower end of the guide block 3212 and engages in the locking groove 3212a, preventing the locking member 322 from moving upward. At this point, the locking member 322 and the guide block 3212 are locked. Continuing to press down on the microphone body 1, the hook 3231 slides vertically out of the locking groove 3212a, and under the reset torque of the torsion spring 324, the swing hook 323 swings to the right, disengaging the hook 3231 from the locking groove 3212a, thus unlocking the locking member 322 and the guide block 3212. Under the push of the reset member 33, the base 2 moves away from the microphone body 1, causing the hook 3231 to slide upward along the second inclined surface 3212c to complete the reset.

[0152] In this embodiment, the inner wall of the lifting channel 3211 is also provided with a stop block 3213. The stop block 3213 is located at the lower end of the guide block 3212, and the stop block 3213 is positioned to the left of the locking groove 3212a. When the hook 3231 slides along the first inclined surface 3212b to the bottom end of the guide block 3212, the hook 3231 disengages from the obstruction of the first inclined surface 3212b. Driven by the rightward deflection of the torsion spring 324, the hook 3231 deflects to the right to slide into the locking groove 3212a. If the user presses too hard during the sliding process of the hook 3231, the hook 3231 will cross the locking groove 3212a and swing directly to the right side of the locking groove 3212a, resulting in failure to engage. In this embodiment, the stop block 3213 is located on the swing path. When the hook 3231 swings to the right, it will collide with the stop block 3213. The stop block 3213 prevents the hook 3231 from continuing to swing to the right, so that the hook 3231 slides into the locking groove 3212a along the stop block 3213, thereby completing the locking.

[0153] The locking assembly 32 also includes a driving member 325, which is located between the locking member 322 and the bottom wall of the lifting channel 3211. The driving member 325 drives the locking member 322 to spring upward. The driving member 325 is a spring, with its two ends abutting against the bottom wall of the lifting channel 3211 and the bottom of the locking member 322, respectively. The driving member 325 generates a spring force that causes the locking member 322 to slide upward along the lifting channel 3211. When the hook 3231 disengages from the locking groove 3212a, the locking member 322 switches to the unlocked state. The driving member 325 pushes the locking member 322 upward, causing the two grippers 3221 on the locking member 322 to slide out of the lifting channel 3211, thus separating the grippers 3221 from the fixing member 31. The driving member 325 and the reset member 33 act in the same direction. The driving member 325 acts directly on the locking member 322, while the reset member 33 acts directly on the microphone body 1 and the base 2.

[0154] In this embodiment, the matching relationship between the microphone body 1 and the base 2 is the same as in embodiment 1. The connection is achieved by the second protruding edge 11 provided on the inner wall of the microphone body 1 facing the base 2, and the first protruding edge 21 provided on the outer side of the base 2 in conjunction with the second protruding edge 11.

[0155] The microphone body 1 has a first positioning post 12 at its lower end, and the first positioning post 12 has a positioning groove 121. The base 2 has a second positioning post 22 that is inserted into the positioning groove 121 to restrict the rotation of the base 2.

[0156] Example 6:

[0157] As shown in Figures 48-52, an active lifting microphone differs from Embodiment 1 in that the lifting device 3 includes a coaxially mounted fixing member 31, a rotating member 32, and a pressing member 33. The fixing member 31 is installed at the bottom of the base 2. One end of the pressing member 33 abuts against the bottom of the microphone body 1, and the other end of the pressing member 33 is slidably connected to the fixing member 31. The two ends of the rotating member 32 are respectively connected to the fixing member 31 and the pressing member 33. The rotating member 32 has a locked state when it is initially pressed down by the pressing member 33, descending relative to the fixing member 31 and locking onto the fixing member 31; and an unlocked state when it is pressed down again by the pressing member 33, rising relative to the fixing member 31 and sliding onto the fixing member 31.

[0158] Initially, the rotating part 32 is locked. When the microphone needs to be removed from the speaker, the microphone body 1 is pressed, causing the microphone body 1 to descend along with the pressing part 33. The pressing part 33 drives the rotating part 32 to descend and rotate simultaneously, thereby releasing the lock between the rotating part 32 and the fixed part 31. This unlocks the rotating part 32, allowing it to slide upwards along the fixed part 31, thus lifting the pressing part 33 and the microphone body 1, achieving the microphone's upward movement. When the microphone needs to be hidden inside the speaker body 4, it needs to be lowered. At this time, the user presses the microphone body 1 again, causing the pressing part 33 to descend again. The pressing part 33 drives the rotating part 32 to descend and rotate simultaneously, thus rotating the rotating part 32 to the locked position with the fixed part 31, achieving the locked state. At this time, the rotating part 32 cannot slide upwards along the fixed part 31, thus keeping the pressing part 33 and the microphone body 1 in their current positions, achieving the microphone's downward movement.

[0159] This embodiment achieves the switching between the microphone's initial press-to-lock and secondary press-to-unlock states using only the simple structural design of the lifting device 3, thereby quickly raising and lowering the microphone. The structure is simple and stable, reducing manufacturing costs and the failure rate, making it convenient for users and reducing their operating costs.

[0160] Referring to Figures 50 and 51, the pressing member 33 is slidably inserted into the fixing member 31. A plurality of sliders 331 are evenly distributed along the circumference of the outer side wall of the pressing member 33. The inner side wall of the fixing member 31 is provided with a first sliding groove 311 and a plurality of second sliding grooves 312 that are slidably inserted into the plurality of sliders 331. The first sliding grooves 311 and the second sliding grooves 312 are arranged alternately in sequence. The sliders 331 are slidably inserted into the first end of the first sliding groove 311 and the second sliding groove 312 respectively.

[0161] In this embodiment, the pressing component 33 moves up and down along a predetermined path along the slide during the lifting process, ensuring the smoothness and reliability of the microphone's lifting and lowering. This avoids user experience issues caused by shaking or jamming during the lifting and lowering process. Simultaneously, it enhances the connection stability between the pressing component 33 and the fixing component 31, ensuring the structural stability of the lifting device 3 during the lifting and lowering process. The sliding plug-in connection method makes the installation and disassembly of the pressing component 33 and the fixing component 31 more convenient. Users can lift and lower the microphone simply by pressing, eliminating the need for complex operating steps and improving ease of use.

[0162] The outer side wall of the rotating component 32 is evenly distributed with a number of locking blocks 321 along its circumference. The second ends of the first slide groove 311 and the second slide groove 312 are provided with openings for the locking blocks 321 to slide into. The second slide groove 312 is provided with a limiting protrusion 313 for locking the position of the locking blocks 321.

[0163] In this embodiment, a limiting protrusion 313 is added in the second slide groove 312 to limit the displacement of the locking block 321. By switching the locking block 321 between the first slide groove 311 and the second slide groove 312, the locking state and unlocking state of the rotating part 32 can be switched. Specifically, referring to Figure 50, it can be seen that the second slide groove 312 is provided with a limiting protrusion 313. Therefore, the path for the locking block 321 to slide within the second slide groove 312 is small. The rise of the locking block 321 is met by the limiting protrusion 313, thus restricting the locking block 321 from rising along the second slide groove 312 and locking the rotating part 32. Therefore, when the rotating part 32 is located within the second slide groove 312, the rotating part 32 is in a locked state, and the microphone body 1 is in a lowered state. When it is necessary to raise the microphone body 1, press the microphone body 1, and the rotating part 32 will descend through the pressing part 33. When the rotating part 32 descends, it separates from the second slide groove 312. At the same time, the end of the locking block 321 near the pressing part 33 is set with an inclined surface, and the end of the pressing part 33 is provided with an abutment that abuts against the inclined surface. When the pressing member 33 is pressed down, the abutting part 332 presses down the inclined surface to drive the rotating member 32 to descend and rotate synchronously. During the rotation of the rotating member 32, a guide inclined surface 314 adapted to the inclined surface is provided between the openings of the first slide groove 311 and the second slide groove 312, thereby guiding the locking block 321 from the second slide groove 312 into the first slide groove 311. After the locking block 321 enters the first slide groove 311, since no limiting protrusion 313 is provided in the first slide groove 311, the path of the rotating block rising along the first slide groove 311 is much larger than the path of rising along the second slide groove 312, thereby realizing the rise of the rotating member 32, driving the pressing member 33 to rise, and realizing the rise of the microphone body 1.

[0164] An elastic element 34 is also installed inside the base 2, with its two ends abutting against the rotating element 32 and the base 2, respectively. In this embodiment, by setting the elastic element 34, the elastic element 34 is compressed when the rotating element 32 descends, and is in a compressed state when the rotating element 32 is in a locked state. When the rotating element 32 is unlocked, it will rise under the elastic restoring force of the elastic element 34, completing the automatic raising and lowering of the rotating element 32.

[0165] Referring to Figure 52, in this embodiment, the matching relationship between the microphone body 1 and the base 2 is the same as in Embodiment 1. The connection is achieved by the snap-fit ​​of the second protruding edge 11 provided on the inner wall of the microphone body 1 facing the base 2 and the first protruding edge 21 provided on the outer side of the base 2 in conjunction with the second protruding edge 11.

[0166] A limiting post 22 is provided on the outer wall of the base 2 along its axial direction, and a limiting groove 12 is provided on the inner wall of the microphone body 1 to engage with the limiting post 22. The engagement between the limiting post 22 on the outer wall of the base 2 and the limiting groove 12 on the inner wall of the microphone body 1 effectively restricts the rotational freedom of the microphone body 1 relative to the base 2, thereby effectively preventing structural damage or component misalignment caused by accidental twisting during lifting, lowering, or use, ensuring that the microphone always maintains correct directionality. Simultaneously, the axial engagement structure between the limiting post 22 and the limiting groove 12 not only prevents rotation but also provides guidance for the lifting and lowering movement of the microphone. During lifting and lowering, the limiting groove 12 slides along the axial direction of the limiting post 22, ensuring that the microphone body 1 rises and falls smoothly along a predetermined trajectory, avoiding deviation or jamming, and further optimizing the user experience.

[0167] The main bodies of the fixing component 31, the pressing component 33, and the rotating component 32 are all cylindrical. The cylindrical design of the fixing component 31, the pressing component 33, and the rotating component 32 fully utilizes axial space and reduces radial dimension occupation. The rotational symmetry of the cylindrical structure ensures that the lifting device 3 experiences uniform force during rotation and axial movement, avoiding jamming or wear.

[0168] Example 7:

[0169] As shown in Figures 53-59, an active lifting microphone differs from Embodiment 1 in that the lifting device 3 includes a fixed component 32, a reset component 33, and a locking component 31. The fixed component 32 includes a fixed component 321 and a movable component 322, which is movably connected to the fixed component 321, and a locking gap 323 is formed between the movable component 322 and the fixed component 321. The reset component 33 is disposed between the microphone body 1 and the base 2. The locking component 31 is retractably and movably disposed on the side of the fixed component 32, and in the extended state, the locking component 31 is embedded in the locking gap 323 to lock the microphone and the base 2.

[0170] In this embodiment, the microphone body 1 is slidably inserted into the base 2. The locking component 31 and the fixing component 32 are respectively fixed to the microphone body 1 and the base 2. By pressing the microphone body 1, the locking component 31 is inserted into the locking gap 323 and locked. At this time, the microphone body 1 cannot slide upward relative to the base 2, so that the microphone can be stored in the speaker. When the microphone is removed, the microphone body 1 is pressed again, causing the locking component 31 to slide out of the locking gap 323 and switch to the unlocked state. Under the push of the reset component 33, the locking component 31 separates from the fixing component 32, and the microphone body 1 pops upward.

[0171] In this embodiment, the reset member 33 is a spring, and its two ends abut against the bottom wall of the microphone body 1 and the bottom wall of the base 2, respectively. When the microphone body 1 and the base 2 are relatively close, the reset member 33 is compressed by the downward pressure from the microphone body 1, generates elastic deformation, and stores the elastic force that causes the microphone body 1 and the base 2 to separate from each other. When the locking component 31 slides out from the locking gap 323 and switches to the unlocked state, the reset member 33 releases the elastic force, so that the microphone body 1 pops upward.

[0172] The fixing component 32 is mounted on the base 2, and the locking component 31 is mounted on the bottom of the microphone. Specifically, the locking component 31 is integrally fixedly installed on the bottom of the microphone body 1, the fixing component 32 is fixedly installed on the base 2, and the reset component 33 is located between the microphone body 1 and the base 2. The fixing component 32 includes a fixing component 321 and a movable component 322. The fixing component 32 can be fixedly connected to the base 2 by screws or adhesive. When the automatically height-adjustable microphone is stored in the speaker, the user presses the microphone body 1, causing the microphone body 1 to slide downward and move closer to the base 2. The locking component 31 moves downward with the microphone body 1 and is embedded in the locking gap 323 of the fixing component 32, achieving a locked state. At this time, the microphone body 1 cannot slide upward relative to the base 2, thus being stably stored in the speaker. When the microphone needs to be removed, the user presses the microphone body 1 again, causing the locking component 31 to slide downwards and disengage from the locking gap 323, thus switching the locking component 31 to the unlocked state. Driven by the reset component 33, the microphone body 1 moves upwards, allowing the upper end of the microphone body 1 to extend beyond the speaker enclosure surface, facilitating the user's removal of the automatically lifting microphone. If the lifting device 3 malfunctions and requires repair or replacement, only the microphone body 1 and base 2 need to be disassembled for repair; the speaker enclosure does not need to be disassembled, making repair and replacement convenient.

[0173] The locking assembly 31 includes a mounting base 312, a locking member 311, and a driving member 313. The mounting base 312 is provided with a mounting hole 3122. The locking member 311 is disposed in the mounting hole 3122. The driving member 313 is disposed in the mounting hole 3122 and is used to drive the locking member 311 to extend out of the mounting hole 3122 so that the locking member 311 is embedded in the locking gap 323. In this embodiment, the mounting base 312 is fixed to the bottom of the microphone body 1 and coaxially arranged with the fixing component 32 on the base 2. Two mounting holes 3122 are radially symmetrically opened on the mounting base 312. A locking member 311 and a driving member 313 are arranged in the mounting holes 3122. A locking seat 3111 is provided at the end of the locking member 311 away from the fixing component 32. The locking seat 3111 is fixedly arranged in the mounting hole 3122. The locking member 311 is inserted into the locking seat 3111. The driving member 313 is a spring. The driving member 313 is sleeved on the locking member 311. One end of the driving member 313 abuts against the locking seat 3111, and the other end abuts against the locking member 311, so as to drive the locking member 311 to extend out of the mounting hole 3122 and embed into the locking gap 323. When the microphone body 1 is pressed downwards, the locking member 311 slides downwards. When the locking member 311 moves to the position of the fixing member 321, the fixing member 321 abuts against the locking member 311. At this time, the microphone body 1 continues to move downwards, and the locking member 311 retracts into the mounting hole 3122 under the compression of the fixing member 321. The driving member 313 is in a compressed state. When the locking member 311 slides down to the locking gap 323, the driving member 313 releases the compression force to drive the locking member 311 out of the mounting hole 3122, so that the locking member 311 is embedded in the locking gap 323, thereby locking the locking component 31 and the fixing component 32. When the microphone body 1 continues to be pressed downwards, the locking member 311 slides out of the locking gap 323, and the locking component 31 and the fixing component 32 are unlocked.

[0174] The fixing member 321 includes a guide portion 3211 and a connecting portion 3212. The guide portion 3211 is trapezoidal and a first inclined surface 3213 is formed on the periphery of the guide portion 3211. The connecting portion 3212 is cylindrical. The movable member 322 is trapezoidal. A locking gap 323 is formed between the lower end face of the guide portion 3211 and the upper end face of the movable member 322. Specifically, the guide portion 3211 is trapezoidal, with a first inclined surface 3213 forming on its periphery that slopes upwards along the axis. A connecting portion 3212 is provided at the lower end of the guide portion 3211. The connecting portion 3212 is cylindrical, and the movable member 322 is inverted trapezoidal. The movable member 322 is fitted onto the connecting portion 3212 and can slide axially along the connecting portion 3212. The connecting portion 3212 passes through the movable member 322 and is fixed to the base 2. When the upper end face of the movable member 322 naturally separates from the lower end face of the guide portion 3211, a locking gap 323 is formed, which is annularly distributed. When the locking member 311 moves downwards, it slides along the first inclined surface 3213 of the guide portion 3211 and embeds into the locking gap 323, locking the locking member 311 with the fixing component 32. When the microphone body 1 continues to move downwards, the locking member 311 slides out of the locking gap 323, unlocking the locking member 311 from the fixing component 32. The inclined structure of the guide section 3211 reduces sliding resistance and ensures smooth locking action.

[0175] The area of ​​the lower end face of the guide portion 3211 is larger than the area of ​​the upper end face of the movable member 322. Because the area of ​​the lower end face of the guide portion 3211 is larger than the area of ​​the upper end face of the movable member 322, there is a size difference between the fixed member 321 and the movable member 322. When the locking member 311 slides along the first inclined surface 3213 of the guide portion 3211 to the locking gap 323, the size difference between the fixed member 321 and the movable member 322 will cause the locking member 311 to be stuck in the locking gap 323. At this time, the upper end face of the movable member 322 acts as a limit to the locking member 311, thereby preventing the locking member 311 from coming out of the locking gap 323, and thus achieving a stable locking state. If the area of ​​the lower end face of the guide part 3211 is equal to the area of ​​the upper end face of the movable part 322, the locking part 311 cannot be stably engaged in the locking gap 323, and the movable part 322 cannot effectively restrict the locking part 311. Under the action of gravity or external force, the locking part 311 is very likely to slide out of the locking gap 323, which will cause the microphone body 1 and the base 2 to fail to achieve a stable locking function.

[0176] The locking member 311 has a locking portion 314 at one end near the fixing component 32. The locking portion 314 has a wedge-shaped structure, and a second inclined surface 3141 is formed on the side of the locking portion 314 near the fixing component 32. The second inclined surface 3141 slides along the first inclined surface 3213, and the locking portion 314 slides into the locking gap 323, thus locking the locking member 311 and the fixing component 321. Specifically, the locking member 311 has a locking portion 314 at one end near the fixing component 321. The locking portion 314 has a wedge-shaped structure, with its upper end surface being a plane and its lower end surface being a second inclined surface 3141 that slopes upward. When the locking member 311 moves downward, the second inclined surface 3141 of the engaging portion 314 abuts against the first inclined surface 3213 of the guide portion 3211 and slides downward along the first inclined surface 3213. When the engaging portion 314 slides along the first inclined surface 3213 to the locking gap 323, the upper end surface of the engaging portion 314 abuts against the lower end surface of the guide portion 3211, thereby allowing the locking member 311 to engage in the locking gap 323. When the locking member 311 slides out of the locking gap 323, the second inclined surface 3141 of the engaging portion 314 slides out of the locking gap 323 along the upper end surface of the movable member 322, thereby releasing the locking member 311 from the locking gap 323.

[0177] The movable part 322 has a third inclined surface 3221 on its periphery. The locking part 311 slides along the third inclined surface 3221, and the snap-fit ​​part 314 disengages from the locking gap 323, thus unlocking the locking part 311 from the fixing part 321. When it is necessary to unlock the microphone body 1 and the base 2, press down on the microphone body 1. The second inclined surface 3141 of the latching part 314 slides out of the locking gap 323 along the upper end surface of the movable part 322 and slides down along the third inclined surface 3221. At this time, the locking part 311 is unlocked from the locking gap 323. When the latching part 314 slides to the bottom of the movable part 322, the latching parts 314 on both sides clamp the movable part 322 and drive the locking part 311 to move the movable part 322 upward synchronously through the reverse reset force of the reset part 33 until the upper end surface of the movable part 322 is in contact with the lower end surface of the fixed part 321 to eliminate the locking gap 323. At this time, the locking part 311 passes over the fixed part 321 and continues to move upward, thereby unlocking the microphone body 1 and the base 2.

[0178] The mounting base 312 is a hollow cylinder with a guide channel 3121 on its inner wall for guiding the sliding of the fixing component 32. The guide channel 3121 is located on the inner wall of the mounting base 312 and extends axially along the mounting base 312. A locking member 311 is disposed in the guide channel 3121 and slides along the guide channel 3121 to lock or unlock with the locking gap 323. A latching part 314 locks or unlocks the locking member 311 by engaging or disengaging with the locking gap 323. The diameter of the guide channel 3121 is larger than the diameter of the mounting base 312, allowing the fixing component 32 to slide up and down within the guide channel 3121. When the microphone body 1 is pressed down, the locking member 311 slides down along the guide channel 3121, and the latching part 314 engages with the locking gap 323, locking the locking component 31 and fixing the component 32. When the microphone body 1 continues to be pressed down, the latching part 314 disengages from the locking gap 323, and the locking component 31 and fixing the component 32 switch to the unlocked state.

[0179] In this embodiment, the matching relationship between the microphone body 1 and the base 2 is the same as in embodiment 1. The upper edge of the base 2 is provided with a first protruding edge 21, and the lower inner side of the microphone body 1 is provided with a second protruding edge. The connection is achieved by the second protruding edge engaging with the first protruding edge 21.

[0180] Example 8:

[0181] As shown in Figures 60-61, an active lifting microphone differs from Embodiment 1 in that the lifting device 12 is disposed within the mounting cavity 113 and electrically connected to the controller 14 for adjusting the distance between the microphone body 11 and the base 112. The active lifting microphone also includes a sensing module 13 disposed on the microphone body 11 for detecting contact signals, and a controller 14 disposed within the microphone body 11 and electrically connected to the sensing module 13 for controlling the lifting device 12 to operate when a contact signal is received.

[0182] The outer shell 111 is the outer protective shell of the microphone, used to enclose and protect the internal electronic components. The bottom of the outer shell 111 has a sliding connection structure that allows it to slide against the base 112. The base 112 is the bottom structure of the microphone body 11, forming a mounting cavity 113 with the outer shell 111. Furthermore, the front end of the base 112 has a structure that slides against the outer shell 111, allowing the outer shell 111 and base 112 to slide relative to each other. The mounting cavity 113, enclosed by the outer shell 111 and the base 112, is used to mount the lifting device 12.

[0183] The sensing module 13 is disposed on the surface or inside the outer shell 111 of the microphone body 11 and is used to detect contact signals. Specifically, it can be disposed under the microphone grille 114 on the top of the microphone body 11. When a user touches or approaches the microphone, the sensing module 13 can collect the corresponding contact signal.

[0184] The controller 14 is the core control unit of the microphone body 11, located inside the microphone body 11, and electrically connected to the sensing module 13 and the lifting device 12. When the sensing module 13 detects a contact signal, it transmits the signal to the controller 14. In one usage scenario, the controller 14 can determine whether to control the lifting device 12 based on the received signal through its internal program. Specifically, when the controller 14 receives a contact signal, it generates a lift command through its internal program, controlling the lifting device 12 to raise the microphone body 11 relative to the base 112, thus putting the active lifting microphone in a raised state. At this time, a portion of the microphone body 11 will protrude from the vertically positioned speaker storage slot, allowing the user to easily remove the active lifting microphone. Of course, in another usage scenario, the controller 14 can also generate a retract command based on other signals, controlling the lifting device 12 to move the base 112 from away from the microphone body 11 to closer to the microphone body 11, thus putting the active lifting microphone in a retracted state, i.e., returning it to normal use, to avoid affecting the user experience.

[0185] The lifting device 12 is a key component that drives the housing 111 to move relative to the base 112, and it is located inside the mounting cavity 113. The lifting device 12 is electrically connected to the controller 14 and is used to receive commands from the controller 14 to operate. When the controller 14 issues a lifting command, the lifting device 12 can drive the housing 111 to slide relative to the base 112. Since the base 112 abuts against the bottom of the speaker storage slot, the base 112 will not move when the lifting device 12 can drive the housing 111 to slide relative to the base 112. At this time, the housing 111 will move relative to the base 112 in the direction of the extension of the microphone body 11, realizing the separation between the housing 111 and the base 112. At this time, a part of the microphone body 11 will protrude from the vertically set speaker storage slot, and the user can easily take out the active lifting microphone. Conversely, when the controller 14 issues a retraction command, the lifting device 12 can drive the base 112 to slide relative to the outer shell 111, so that the base 112 changes from being away from the microphone body 11 to being close to the microphone body 11, so that the active lifting microphone is in a retracted state, so as not to affect the user experience.

[0186] In some optional embodiments, the lifting device 12 includes a drive motor 121, a transmission gear 122, and a transmission bar 123. The drive motor 121 is fixed on the base 112, the transmission gear 122 is fixed on the shaft of the drive motor 121, and the transmission bar 123 is fixed on the outer shell 111. The transmission bar 123 meshes with the transmission gear 122 for transmission. The drive motor 121 is used to drive the transmission bar 123 to move up and down through the transmission gear 122, so as to realize the approach or separation between the outer shell 111 and the base 112.

[0187] In this embodiment, the drive motor 121 is the power source of the lifting device 12, providing the necessary torque to drive the movement of other components. The drive motor 121 can be fixed to the base 112 to ensure that the motor will not move due to external forces during operation, and also facilitates the connection of the motor to the power supply and control system. The transmission gear 122 is fixed on the shaft of the drive motor 121, and when the drive motor 121 rotates, the transmission gear 122 will also rotate. The function of the transmission gear 122 is to convert the rotational motion of the drive motor 121 into a specific transmission ratio to adapt to the movement requirements of the transmission bar 123. The transmission bar 123 is a key component connecting the housing 111 and the transmission gear 122. It is fixed to the housing 111, arranged along the extension direction of the microphone body 11, and meshes with the transmission gear 122. When the transmission gear 122 rotates, the transmission gear 122 will push the transmission bar 123 up and down through the meshing relationship, thereby driving the housing 111 to move up and down.

[0188] This embodiment of the application utilizes a motor drive and a transmission mechanism involving gears and a transmission bar 123 to easily move the housing 111 of the active lifting microphone up and down, thereby adjusting the microphone's position or shape according to user needs. Furthermore, because the drive motor 121 is fixed to the base 112 and the transmission mechanism is rationally designed, the entire lifting process exhibits high stability, reducing noise and vibration caused by movement. In addition, this lifting device 12 is relatively simple and versatile, applicable to different types of active lifting microphone products; only the transmission ratio and the length of the transmission bar 123 need to be adjusted according to specific requirements. In some alternative embodiments, the drive motor 121 is fixed to the housing 111, and the transmission bar 123 is fixed to the base 112.

[0189] The embodiments of this application can also achieve the approach or separation between the outer shell 111 and the base 112 under the drive of the lifting device 12, but the implementation principles of the two settings are different. In the aforementioned settings, during the process of the active lifting microphone rising, the drive motor 121, the transmission gear 122, and the base 112 remain stationary, driving the transmission bar 123 to move upward, thereby driving the active lifting microphone to rise. In the embodiments of this application, the transmission bar 123 and the base 112 remain stationary, driving the drive motor 121 and the transmission gear 122 to move upward relative to each other, thereby driving the active lifting microphone to rise.

[0190] In some optional embodiments, the base 112 has a first protruding edge 1121 at the end near the outer shell 111, and the outer shell 111 has a second protruding edge 1111 at the end near the base 112. The first protruding edge 1121 can be annular, strip-shaped, or other shapes. The main function of the first protruding edge 1121 is to provide positioning, limiting, support, or sealing functions with the outer shell 111. The second protruding edge 1111 corresponds to the first protruding edge 1121, and its shape, size, and position should match the first protruding edge 1121 to ensure that the two can achieve relative sliding, engagement, or sealing functions. In some specific embodiments, a sealing material (such as a rubber gasket, silicone ring, etc.) is also provided between the first protruding edge 1121 and the second protruding edge 1111 to improve the microphone's waterproof, dustproof, or sound insulation performance.

[0191] In some alternative embodiments, the sensing module 13 includes a pressure sensor 131 and a temperature sensor 132, and the microphone body 11 includes a microphone mesh 114, with the pressure sensor 131 and the temperature sensor 132 disposed under the microphone mesh 114.

[0192] In this embodiment, pressure sensor 131 is used to detect changes in pressure experienced by itself. Temperature sensor 132 can be used to detect whether the pressure sensor 131 has been triggered by the user. Microphone mesh 114 is located at the front end of microphone body 11 and is the part that the user directly contacts. It not only protects the microphone components but also prevents dust and foreign objects from entering. Sensing module 13 (including pressure sensor 131 and temperature sensor 132) is disposed under microphone mesh 114 to better sense changes in the external environment. The sensors can be connected to controller 14 inside microphone body 11 via wires or wirelessly (such as Bluetooth, Wi-Fi, etc.).

[0193] Understandably, when the active lifting microphone is stored in the vertically positioned storage slot inside the external speaker enclosure, the user can press the head of the microphone. At this time, the pressure sensor 131, located under the microphone grille 114, can sense the pressure applied by the user and send a relevant signal to the controller 14. However, in some scenarios, other objects may accidentally touch the head of the active lifting microphone. In this case, the pressure sensor 131 can still sense the pressure and send a relevant signal to the controller 14, potentially causing the controller 14 to misinterpret it as the user pressing the head of the microphone. This could lead the controller to activate the lifting device 12, causing the active lifting microphone to extend out of the storage slot, potentially resulting in a poor user experience.

[0194] Alternatively, in an external speaker with a screen, when the active lifting microphone is stored in the storage slot of the external speaker with a screen, and the screen of the external speaker is retracted and covers the top of the active lifting microphone, if an external force presses on the screen, the screen may transmit pressure to the active lifting microphone. At this time, the pressure sensor 131 may sense the pressure and send a relevant signal to the controller 14. The controller will then control the lifting device 12 to work and make the active lifting microphone extend out of the storage slot. At this time, the active lifting microphone will come into contact with the screen of the external speaker, and may even continuously press on the screen, causing damage to the screen.

[0195] In view of this, the embodiment of this application also includes a temperature sensor 132, and the controller 14 can be configured to operate only when it receives a pressure signal collected by the pressure sensor 131 and a temperature signal collected by the temperature sensor 132 at the same time, and the temperature signal is within a preset range (the normal temperature range of a human finger). This can effectively prevent other objects from accidentally triggering the pressure sensor 131, causing the active lifting microphone to extend out of the storage slot, thereby improving the user experience and avoiding damage to the screen or other components of the external speaker.

[0196] In some alternative embodiments, a magnetic component is provided inside the microphone body 11. The magnetic component is used to attract and fix the active lifting microphone to an external magnetic component when the active lifting microphone is in the retracted position.

[0197] In this embodiment, the magnetic component is a material capable of generating a magnetic field, such as a magnet or ferrite. The external magnetic component is a component that matches the magnetic component of the active-lift microphone. It can be placed in the storage slot of the external speaker enclosure at a position corresponding to the storage location of the active-lift microphone, so as to attract the magnetic component inside the microphone body 11, thereby fixing the active-lift microphone in place. Specifically, the magnetic component inside the microphone body 11 can be a magnet or iron, or a material that can be attracted by a magnet. The external magnetic component in the storage slot of the external speaker enclosure can also be a magnet or iron, or a material that can be attracted by a magnet, but it is necessary to ensure that the two can attract each other. For example, the magnetic component inside the microphone body 11 can be a magnet, and the external magnetic component in the storage slot of the external speaker enclosure can be an iron block. The active-lift microphone being in the storage position means that the active-lift microphone is completely stored in the storage slot of the external speaker enclosure, that is, the outer shell 111 and the base 112 are in contact.
