[0040] One embodiment of this utility model provides a self-lifting microphone, comprising:
[0041] Microphone body 1, with a transmission component 2 installed at the bottom of the microphone body 1;
[0042] Base 3, the bottom of the microphone body 1 is slidably inserted into the base 3;
[0043] The lifting transmission mechanism 4 is installed inside the base 3. The lifting transmission mechanism 4 includes a rotary drive component 41. The drive end of the rotary drive component 41 is connected to a rotating disk 42. The rotating disk 42 is connected to the transmission component 2 to drive the transmission component 2 to move up and down.
[0044] In existing technology, a microphone is housed in a recessed slot inside the speaker enclosure, with a lifting mechanism within this slot to raise or lower the microphone for easy access. However, this lifting mechanism occupies a significant amount of space within the speaker enclosure, affecting the overall layout. Furthermore, if the lifting mechanism malfunctions, the entire speaker enclosure needs to be sent for repair. The speaker enclosure is also heavy, resulting in high shipping costs.
[0045] This embodiment improves the microphone's structure, reducing the space it occupies inside the speaker enclosure. Furthermore, the lifting mechanism is integrated inside the microphone, so if the lifting mechanism malfunctions, the microphone only needs to be sent for repair, reducing the burden on the user.
[0046] refer to Figures 1 to 4When the rotary drive 41 is started, 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.
[0047] Further, refer to Figures 4 to 6 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.
[0048] 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 plurality of transmission teeth 43 that mesh with the transmission grooves 21 along its circumference. In any rotation state, the plurality of transmission teeth 43 only mesh with one set of transmission grooves 21 for transmission.
[0049] In existing smart speaker microphone storage structures, the transmission mechanism often employs complex gear, chain, or lead screw transmission methods. While these methods can achieve microphone lifting, they are structurally 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 adopted, which ensures transmission stability while greatly simplifying the transmission structure and reducing costs. Specifically, when the rotary drive 41 is activated 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 motion and realize the lifting of the microphone body 1. It should be noted that this embodiment adopts a double transmission groove 21 structural design to ensure transmission stability and balance. 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 meshing, avoiding motion jamming. More importantly, the entire process of the rotary drive component 41 only requires rotating 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 simplifies the design of the drive circuit and reduces costs.
[0050] Furthermore, the transmission component 2 is provided with a rectangular slot 22, and the two sets of transmission slots 21 are respectively arranged on one set of symmetrical sides of the rectangular slot 22.
[0051] In this embodiment, by creating a rectangular slot 22 on the transmission component 2, the overall weight is reduced, and the strength of the transmission component 2 is enhanced through a 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 groove 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.
[0052] Furthermore, the transmission process between the transmission component 2 and the rotating disk 42 is referenced. Figures 7-10 Detailed explanation:
[0053] It should be noted that the figure shows the relative positions of the transmission component 2 and the rotating disk 42. During actual transmission, the rotating disk 42 remains stationary, 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 lifted, i.e., the transmission component 2 needs to be lifted. 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. (Refer to...) Figure 8 This is a diagram showing the state of transmission component 2 during its lifting process. After transmission gear 43 separates from the left transmission groove 21, it engages with the right transmission groove 21. At this point, refer to... Figure 9 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 for easy removal of the microphone. When the microphone body 1 needs to be retracted, the rotation drive component 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. (Refer to...) Figure 10 This is a state diagram showing the descent of transmission component 2. Finally, when the rotating disk 42 is at the top of the rectangular slot 22, that is, when transmission component 2 is at its lowest point, it returns to its initial position, as shown below. Figure 7 As shown, at this time, the microphone body 1 is retracted.
[0054] Further, refer to Figure 3 and Figure 4 The microphone body 1 includes a housing 11, the transmission component 2 is installed inside the housing 11, the housing 11 is slidably inserted into the base 3, the base 3 has a first protruding edge 31 on the outer periphery of its end, and the housing 11 has a second protruding edge 12 that abuts against the first protruding edge 31 at its end.
[0055] In this embodiment, the outer shell 11 and the base 3 are limited by a first protruding edge 31 and a second protruding edge 12. When the outer shell 11 is inserted into the base 3, during the lifting and lowering process of the outer shell 11 on the base 3, the second protruding edge 12 on the outer shell 11 is in contact with the outer side of the base 3, and the first protruding edge 31 on the base 3 is in contact with the inner side of the outer shell 11. The first protruding edge 31 and the second protruding edge 12 play an effective guiding and positioning role. This structure can ensure the stability of the microphone body 1 during the lifting and lowering process and reduce the shaking and displacement during the lifting and lowering process. At the same time, when the outer shell 11 is raised to the highest point, the second protruding edge 12 slides to the bottom of the first protruding edge 31, and the second protruding edge 12 abuts against the first protruding edge 31. The first protruding edge 31 effectively limits the second protruding edge 12, thereby effectively preventing the microphone body 1 from detaching from the base 3.
[0056] Furthermore, 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 to the base 3, the lifting of the microphone body 1 can be effectively guided, ensuring the stability and smoothness of the lifting process.
[0057] 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.
[0058] Furthermore, 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 a position sensor, precise control of the lifting position of the microphone body 1 can be achieved.
[0059] Furthermore, 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.
[0060] 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.
[0061] One embodiment of this utility model also proposes a smart speaker, including a speaker body 6, wherein the speaker body 6 has a storage slot 61 for mounting any of the microphones described above. Since the smart speaker proposed in this embodiment includes all solutions of all the microphone embodiments described above, it at least has the same technical effects as the microphone, which will not be elaborated here.
[0062] In some embodiments, the storage slot 61 can be a cavity for accommodating and storing a microphone. Specifically, in this embodiment, the storage slot 61 is formed on the storage component. The depth of the storage slot 61 is greater than or equal to the length of the microphone. The storage slot 61 includes an inlet. Through the inlet, the microphone can be inserted vertically or horizontally into the storage slot 61 along its length to achieve insertion-type storage. A microphone fixing structure can be provided inside or outside the inlet to fix the microphone after storage. The inlet can be set at any position on the smart speaker, including the top, side, and bottom surfaces of the smart speaker.
[0063] In some implementations, the smart speaker may have a screen, a movable structure, and a screen storage slot. The screen can be closed using the movable structure and stored within the screen storage slot. The microphone storage slot 61 may be located below the screen, so that when the screen is closed, the microphone is completely covered by the screen and fully stored inside the smart speaker.
[0064] Furthermore, the speaker body 6 is also equipped with a sensing element for sensing the insertion of the microphone into the storage slot 61. It should be noted that when the microphone is connected to the smart speaker, if it gets too close to the smart speaker, it will cause feedback, resulting in a harsh, piercing sound that severely impacts the user experience. This is especially true when the smart speaker is storing the microphone, as the impact and friction noise during storage increases the likelihood of feedback. Therefore, the microphone can be automatically powered off when it approaches the smart speaker to prevent feedback during this process.
[0065] In some implementations, to prevent feedback when the microphone is near a smart speaker or when the microphone is housed in a smart speaker, the microphone can automatically shut down when it is near the smart speaker. Specifically, a sensing element can be placed on the microphone and / or the smart speaker. This sensing element can detect the distance between the smart speaker and the microphone, and generate a corresponding sensing signal when the distance between the smart speaker and the microphone is less than or equal to a preset distance. This sensing signal is then sent to the microphone's control device, or the smart speaker sends the sensing signal to the microphone's control device, causing the control device to shut down the microphone. More specifically, the sensing element can be one or more, and can be a Hall element, a proximity sensor, an infrared sensor, or any other single electronic component capable of sensing the distance between the smart speaker and the microphone, or any combination of electronic components.
[0066] In some specific embodiments, when the microphone housing structure is a cavity, the sensing element can be located at the entrance of the housing slot 61. When the microphone is inserted into the housing slot 61, the sensing element can generate a corresponding sensing signal to turn off the microphone immediately after insertion. Alternatively, the sensing element can be located at the end of the housing slot 61 away from the entrance. It can also generate a corresponding sensing signal to turn off the microphone when it is inserted near the sensing element, and this also prevents the sensing element from being exposed due to the entrance facing outwards, thus preventing component aging.
[0067] In some more specific implementations, the sensing elements are Hall effect sensors and magnetic elements, respectively positioned at corresponding locations on the smart speaker and microphone. For example, a magnetic element may be positioned at the microphone's location and a Hall effect sensor at the smart speaker's location, or vice versa. The trigger condition for the Hall effect sensor can be that the detected magnetic field strength reaches a preset value. When the detected magnetic field strength is greater than or equal to the preset value, it means that the distance between the smart speaker and microphone is sufficient to trigger a feedback sound, at which point the microphone needs to be turned off.
[0068] In some preferred embodiments, a magnetic element is provided at the corresponding position of the microphone and a Hall element is provided at the corresponding position of the smart speaker. Since users carry the microphone around when singing karaoke, they may move to places with strong magnetic fields. If the Hall element is located on the microphone, it may cause the microphone to shut down incorrectly, thus affecting the experience. When the microphone storage structure is a cavity, that is, when the microphone is inserted into the housing, the Hall element can be located at the entrance of the smart speaker storage slot 61 or at the end away from the entrance.
[0069] In some more specific embodiments, the sensing element is a Hall element and a charging element, the charging element including a charging structure and a receiving structure. The smart speaker is equipped with a charging structure, and the microphone is equipped with a receiving structure. It is important to understand that a magnetic field change occurs the instant the charging structure comes into contact with the receiving structure. Based on this, the trigger condition for the Hall element can be set to detect a change in the magnetic field. When the Hall element detects a change in the magnetic field, it means that the charging structure of the smart speaker is in contact with the receiving structure of the microphone. At this time, the distance between the smart speaker and the microphone is sufficient to trigger a howling sound, requiring the microphone to be turned off. Specifically, the charging structure can be located on the surface of the smart speaker or corresponding to the storage structure. When the microphone storage structure is a storage slot 61, that is, when the microphone is inserted into the storage slot 61, the charging structure is located at the end of the smart speaker storage slot 61 furthest from the entrance, and the receiving structure is correspondingly located on the bottom or end face of the microphone. The Hall element can be located near the charging structure, allowing the Hall element to sense the magnetic field change caused by the instant of power-on.
[0070] In some more specific embodiments, the sensing element is a Hall element and a charging element. The charging element includes a charging structure and a receiving structure. The smart speaker is provided with a charging structure, and the microphone is provided with a receiving structure. In addition, the smart speaker and the microphone may also be provided with magnetic components. These magnetic components are located outside the sensing trigger range of the Hall element and are used to fix the microphone rather than trigger the Hall element.
[0071] Furthermore, the microphone base 3 is equipped with a first charging module 32, and the storage slot 61 contains a second charging module corresponding to the first charging module 32. When the microphone is inserted into the storage slot 61, the microphone is automatically charged. The first charging module 32 and the second charging module can employ existing charging structures, such as an insertion-type charging probe structure, a contact-type charging probe structure, or a wireless charging structure. It should be noted that, to further prevent the microphone from rising due to accidental touch, in addition to the signals generated by the pressure sensor and the infrared temperature sensor, a charging signal is added to trigger the microphone's rise. When all three signals are triggered simultaneously, the rotation drive 41 is activated, driving the microphone body 1 to rise.
[0072] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
