Description

Technical Field

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

[0002] In daily life, microphones are usually used in conjunction with speakers. Microphones are generally detachable and placed in a microphone stand or stored inside a speaker. Speakers usually have a sleeve for inserting the microphone, which allows the microphone to be stored, making it convenient to carry and less likely to be lost. When you need to take out the microphone, press down on the microphone, and the microphone will quickly pop out from the sleeve, thus realizing the lifting and retrieval of the microphone.

[0003] Existing speaker enclosures typically feature a manual or electric lift-up and retraction mechanism at the bottom of the speaker sleeve. The microphone is secured when retracted into the sleeve, and pressing it again releases the mechanism, allowing the microphone to be lifted and retracted. However, this mechanism, placed inside the sleeve, occupies significant space within the speaker enclosure, impacting its spatial layout. Utility Model Content

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

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

[0006] Microphone body;

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

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

[0009] The lifting device includes a fixing component, a locking component, and a resetting component. The fixing component is fixed to the microphone body, and the locking component is fixed to the base. The locking component includes a locked state and an unlocked state. The microphone body moves downward to push the locking component to clamp the fixing component. When the locking component reaches the locked state, the microphone body continues to move downward to push the locking component to switch to the unlocked state. The resetting component drives the fixing component to separate from the locking component, causing the microphone body to spring upward and reset.

[0010] Optionally, the locking assembly includes a housing, a locking member, and a swing hook. The housing has a lifting channel, the locking member slides along the lifting channel and is used to clamp and fix the fixing member, one end of the swing hook is rotatably connected to the locking member, and the other end of the swing hook is configured as a hook portion and is locked or unlocked with the housing.

[0011] Optionally, the locking member has two grippers at its end, which elastically open to grip or release the fixing member.

[0012] Optionally, the fixing member is a cylindrical structure, and the end of the fixing member is provided with a protrusion for the gripper to hold.

[0013] Optionally, the locking assembly further includes a torsion spring connected to the swing hook, the torsion spring driving the swing hook to deflect.

[0014] Optionally, the housing is provided with a guide block on the inner wall of the lifting channel. The guide block includes a locking groove, a first inclined surface and a second inclined surface. When the microphone body moves downward, the hook slides along the first inclined surface and engages with the locking groove, and the swing hook locks with the housing. When the microphone body continues to move downward, the torsion spring drives the hook to swing out of the locking groove, and the swing hook unlocks from the housing. The hook slides back to its original position along the second inclined surface.

[0015] Optionally, the locking assembly further includes a driving member located between the locking member and the bottom wall of the lifting channel, the driving member driving the locking member to spring upward.

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

[0017] Optionally, the lower end of the microphone body is provided with a first positioning post, the first positioning post having a positioning groove, and the base is provided with a second positioning post inserted into the positioning groove to restrict the rotation of the base.

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

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

[0042] One embodiment of this utility model provides a height-adjustable microphone, see reference. Figure 1 and Figure 6 The microphone body includes a microphone body 1, a base 2, and a lifting device 3. The microphone body 1 is slidably inserted into the base 2. The lifting device 3 is disposed between the microphone body 1 and the base 2 and is used to adjust the distance between the microphone body 1 and the base 2. The lifting device 3 includes a 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. The microphone body 1 moves downward to push the locking component 32 to clamp the fixing member 31. 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, so that the microphone body 1 springs upward to reset.

[0043] This embodiment incorporates a lifting device 3 inside the microphone, enabling the microphone to actively rise and fall. This avoids the impact on the internal space layout of the speaker caused by placing the lifting device 3 inside the speaker enclosure. Furthermore, the lifting device 3 is integrated within the height-adjustable microphone. If the lifting device 3 malfunctions, the microphone can simply be mailed for repair or replaced directly, effectively avoiding the problem of having to mail the entire speaker enclosure for repair when the lifting device 3, which is built into the speaker enclosure, malfunctions, thus reducing the burden on the user. 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 on 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 upwards relative to the base 2, allowing the microphone to be stored inside the speaker enclosure. When the microphone is removed, pressing the microphone body 1 again unlocks the locking component 32. Under the push of the reset component 33, the locking component 32 separates from the fixing member 31, and the microphone body 1 pops upwards.

[0044] 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.

[0045] 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 height-adjustable microphone is stored inside the speaker, 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 height-adjustable microphone is completely stored inside the speaker. 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, causing the upper end of the microphone body 1 to extend beyond the surface of the speaker, making it convenient for the user to grasp and remove the height-adjustable microphone.

[0046] Specifically, 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, causing the microphone body 1 and the base 2 to separate relative to each other. It can be understood that the reset member 33 can also be two magnets with the same poles repelling each other, with the two magnets respectively mounted on the bottom wall of the slot 13 and the base 2 to generate a magnetic force that separates them.

[0047] Further, 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 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.

[0048] Furthermore, 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 elastic 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.

[0049] Furthermore, the fixing member 31 is a cylindrical structure, and its end is provided with a protrusion 311 for clamping by the gripper 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 gripper 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 gripper 3221 can clamp the upper end face of the protrusion 311 to improve the firmness.

[0050] 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.

[0051] Furthermore, the locking assembly 32 also includes a torsion spring 324 connected to the swing hook 323, the torsion spring 324 driving the swing hook 323 to deflect. In this embodiment, 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 under the drive of the torsion spring 324, the swing hook 323 swings back to reset.

[0052] Furthermore, the housing 321 is provided with 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.

[0053] In the initial state, reference Figure 7The swing hook 323 deflects to the right under the deflection force of the torsion spring 324, causing the hook portion 3231 to point to the right of the center of the guide block 3212, and the hook portion 3231 is located to the right of the locking groove 3212a. (Reference) Figure 8 When the microphone body 1 is pressed down, the locking member 322 is pushed downward by the fixing member 31 and moves downward. The two grippers 3221 clamp and fix the fixing member 31, and the swing hook 323 moves vertically in sync, so that the hook part 3231 abuts against the first inclined surface 3212b and slides downward along the first inclined surface 3212b. During the sliding process of the hook part 3231, the hook part 3231 is pushed by the first inclined surface 3212b, so that the swing hook 323 gradually deflects to the left, and the torsion spring 324 generates the opposite torque force. Reference Figure 9 As the locking element 322 moves downward, the hook 3231 slides to the lower end of the guide block 3212 and engages in the locking groove 3212a, thus preventing the locking element 322 from moving upward. At this point, the locking element 322 and the guide block 3212 are locked together. (Reference) Figure 10 Continue pressing down on the microphone body 1. The hook 3231 slides vertically out of the locking groove 3212a. Under the push of the reset torque of the torsion spring 324, the swing hook 323 swings to the right, causing the hook 3231 to disengage from the locking groove 3212a, thus unlocking the locking member 322 from the guide block 3212. (Continue to refer to...) Figure 7 Under the push of the reset component 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.

[0054] 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.

[0055] Furthermore, 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. In this embodiment, 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, and the driving member 325 pushes the locking member 322 upward so that the two grippers 3221 on the locking member 322 slide out of the lifting channel 3211, separating the grippers 3221 from the fixing member 31. It is understandable that the driving component 325 and the reset component 33 have the same direction of force. The driving component 325 acts directly on the locking component 322, and the reset component 33 acts directly on the microphone body 1 and the base 2.

[0056] Further, refer to Figures 1 to 4 The microphone body 1 has a first protruding edge 11 on its lower inner side, and the base 2 has a second protruding edge 21 on its upper outer side. The upper edge of the first protruding edge 11 abuts against the lower edge of the second protruding edge 21 to prevent the base 2 from detaching from the microphone body 1. In this embodiment, the slot 13 has a first protruding edge 11 on its inner wall, which is arranged in a circumferential manner. The second protruding edge 21 is located on the upper outer wall of the base 2, and its upper side is set as a slope. When the base 2 is inserted into the slot 13, the slope of the second protruding edge 21 abuts against and slides relative to the first protruding edge 11. The first protruding edge 11 presses against the second protruding edge 21, thereby deforming the base 2 and inserting it into the slot 13. The lower side of the second protruding edge 21 is a stop surface. When the microphone body 1 and the base 2 move away from each other, the upper side of the first protruding edge 11 abuts against the lower side of the second protruding edge 21, thereby preventing the first protruding edge 11 from moving and thus preventing the base 2 from accidentally detaching from the slot 13.

[0057] Furthermore, a first positioning post 12 is provided at the lower end of the microphone body 1. The first positioning post 12 has a positioning groove 121. The base 2 is provided with a second positioning post 22 that is inserted into the positioning groove 121 to restrict the rotation of the base 2. The first positioning post 12 is located at the bottom of the slot 13 and extends along the sliding direction of the microphone body 1. The positioning groove 121 is opened along the axial direction of the first positioning post 12. The second positioning post 22 is fixed to the base 2 and corresponds to the position of the first positioning post 12. The shape of the second positioning post 22 is the same as the shape of the positioning groove 121. The diameter of the second positioning post 22 is not greater than the diameter of the positioning groove 121 so that the second positioning post 22 can be inserted to guide the relative sliding of the base 2 and the microphone body 1. Specifically, there are two of each of the first positioning post 12 and the second positioning post 22, so that the two second positioning posts 22 are respectively inserted into the two positioning grooves 121, thereby preventing the base 2 from rotating circumferentially relative to the microphone body 1 within the slot 13.

[0058] refer to Figure 11 and Figure 12 This utility model also provides a smart speaker, including a speaker body 4 and the aforementioned liftable microphone. The speaker body 4 has a storage cavity 41 for mounting the liftable microphone. In this embodiment, the speaker body 4 does not require a separate lifting and storage device inside, thereby improving the space utilization rate inside the speaker body 4 and avoiding affecting its internal spatial layout.

[0059] The storage cavity 41 is located on the surface of the speaker body 4, and its structure is the same as that of the height-adjustable microphone described above. The storage cavity 41 extends in a cylindrical shape, and its depth is less than the length of the height-adjustable microphone. Specifically, when the microphone body 1 and the base 2 are in the unlocked state, the microphone body 1 and the base 2 are relatively far apart. At this time, the lower end of the base 2 abuts against the bottom wall of the storage cavity 41, and the upper end of the microphone body 1 extends out of the storage cavity 41 for the user to hold and remove. When the microphone body 1 and the base 2 are in the locked state, the microphone body 1 and the base 2 are relatively close together. At this time, the lower end of the base 2 abuts against the bottom wall of the storage cavity 41, and the microphone body 1 is completely stored in the storage cavity 41. The upper end of the microphone body 1 does not exceed the surface of the speaker body 4, thereby keeping the speaker body 4 clean after storage and preventing the height-adjustable microphone from being bumped or worn.

[0060] In this embodiment, the bottom or side wall of the storage cavity 41 is provided with a magnetic suction component, which corresponds to the side of the base 2 of the height-adjustable microphone or the microphone body 1, so that the microphone is magnetically fixed after the height-adjustable microphone is stored in the storage cavity 41, preventing the microphone from shaking or accidentally falling off the speaker body 4.

[0061] The speaker body 4 has a charging terminal at the bottom of the storage cavity 41 for charging the liftable microphone. This charging terminal is connected to the power supply component of the speaker body 4. The base 2 of the liftable microphone has a power receiving terminal corresponding to the charging terminal. When the liftable microphone is inserted into the storage cavity 41, the power receiving terminal and the charging terminal abut against each other to achieve an electrical connection, allowing the speaker body 4 to charge the liftable microphone. Specifically, in this embodiment, a magnetic attraction element is provided on the bottom wall of the storage cavity 41, and the liftable microphone is wirelessly charged to the speaker body 4 via a wireless connection. The charging terminal is a wireless charging transmitting coil, and the power receiving terminal is a wireless charging receiving coil.

[0062] It is understandable that the charging method for the height-adjustable microphone can also be a plug-in type. For example, the power receiving terminal is an electrical slot 13, and the charging terminal is an electrical probe. When the bottom of the base 2 abuts against the bottom wall of the storage cavity 41, the electrical probe is inserted into the electrical slot 13, so that the height-adjustable microphone and the speaker body 4 are electrically connected, and the height-adjustable microphone is charged. The charging method for the height-adjustable microphone can also be a contact type. For example, the power receiving terminal is an electrical contact, which is recessed or protruding and set at the bottom of the base 2. The charging terminal is an electrical probe. When the bottom of the base 2 abuts against the bottom wall of the storage cavity 41, the electrical probe abuts against the electrical contact and establishes an electrical connection, so that the height-adjustable microphone is charged.

[0063] Furthermore, the base 2 is also equipped with a sensing element 23 for sensing and controlling the shut-off of the height-adjustable microphone, thereby preventing the height-adjustable microphone from colliding or rubbing when inserted into the storage cavity 41, which could cause feedback. When the microphone is inserted into the storage cavity 41, the sensing element 23 generates a sensing signal to control the microphone to shut down. Alternatively, the sensing element 23 can also be located at the opening of the storage cavity 41. When the height-adjustable microphone is inserted into the opening of the storage cavity 41, the microphone approaches the sensing element 23 and receives the corresponding sensing signal to control the shutdown.

[0064] In some specific embodiments, the sensing element 23 is a Hall element and a magnetic element, which are respectively disposed at corresponding positions on the height-adjustable microphone and the storage cavity 41. For example, the base 2 is provided with a Hall element, and the corresponding position on the side wall or bottom wall of the storage cavity 41 is provided with a magnetic element. The trigger condition of the Hall element can be that the detected magnetic field strength reaches a preset value. When the detected magnetic field strength is greater than or equal to the preset value, it means that the microphone may cause feedback, and the microphone needs to be turned off. It should be noted that the sensing element 23 can also be a proximity sensor, an infrared sensor, or other electronic components.

[0065] 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.
