Technical Field

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

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

[0003] In existing speaker microphone storage structures, the microphone is raised or lowered by setting a manual or electric lifting mechanism inside the speaker. This structure not only occupies a large amount of space inside the speaker, but also affects the spatial layout of the speaker. 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 problems of microphones not being able to actively rise and fall and occupying too much internal space of the speaker body.

[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 and the base for adjusting the distance between the microphone body and the base;

[0009] The lifting device includes a reset component, a hook component, and a locking block. The locking block is disposed on the base. The side of the locking block facing the microphone body has an inclined surface, and the side of the locking block away from the inclined surface has a locking groove.

[0010] Wherein, one end of the hook assembly slides on the inclined surface and engages with the locking groove, and the hook assembly disengages from the locking groove in the natural state of the reset assembly.

[0011] Preferably, the hook assembly includes a mounting block and a swing arm;

[0012] One end of the swing arm is rotatably connected to the mounting block via a torsion spring, and the other end of the swing arm is provided with a hook shaft that engages with the locking groove.

[0013] Preferably, the lifting device further includes a guide assembly, which is installed inside the base and has a guide cavity, the opening of which is located below the swing arm;

[0014] The side of the locking block is fixed to or integrally formed with the inner wall of the guide cavity.

[0015] Preferably, the end of the swing arm away from the mounting block is provided with an arrow-shaped guide block, and the bottom of the guide cavity is provided with a guide fold surface that moves in conjunction with the guide block.

[0016] Preferably, the inner wall of the guide cavity opening end is provided with a flat angle.

[0017] Preferably, the reset assembly includes a reset spring, one end of which is elastically connected to the mounting block and the other end of which is elastically connected to the guide assembly.

[0018] Preferably, the inner wall of the microphone body facing the base has a plurality of first protrusions, the plurality of first protrusions having the same axis, and the outer side of the base has a second protrusion in cooperation with the first protrusions. When the microphone body is inserted into the base, the first protrusion is located below the second protrusion.

[0019] Preferably, the inner wall of the microphone body facing the base has a plurality of limiting posts in a vertical direction, the plurality of limiting posts being arranged in a ring, and the outer side of the base having a groove that fits into the corresponding limiting post.

[0022] The beneficial effects of this utility model are as follows: The height-adjustable microphone slides along the inclined surface of the locking block via a hook assembly and engages with the locking slot, achieving one-button quick lifting and stable locking. The operation is smooth and has strong resistance to displacement. Secondly, the reset assembly can instantly disengage from the locking slot to complete automatic reset. Combined with the low-friction path design of the inclined surface, it reduces component wear and extends service life. The above design adopts an overall hidden structure layout, with mechanical locking to prevent accidental activation and no need for external tools or power supply. It takes into account operational safety, compact space and simple appearance, and solves the problem of the microphone body occupying too much internal space of the speaker body. Furthermore, the lifting device is integrated inside the height-adjustable microphone. When the lifting device fails, only the height-adjustable microphone needs to be mailed for repair or a new height-adjustable microphone needs to be directly replaced. This effectively avoids the problem of having to mail the entire speaker for repair when the lifting device built into the speaker fails, which is common in the prior art, reducing the burden on users.

[0042] This utility model provides a height-adjustable microphone; please refer to [reference needed]. Figures 1-4The height-adjustable microphone includes a microphone body 100, a base 200, and a lifting device. The microphone body 100 is slidably inserted into the base 200. The lifting device is located between the microphone and the base 200 and is used to adjust the distance between the microphone body 100 and the base 200. The lifting device includes a reset component 1, a hook component 2, and a locking block 3. The locking block 3 is located 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. Component 2 disengages from locking slot 32 when component 1 is in its natural state after reset. The above design adopts an integrated hidden layout with mechanical locking to prevent accidental activation and requires no external tools or power supply. It balances operational safety, compact space and simple appearance, and solves the problem that the microphone body 100 occupies too much internal space in the speaker body 300. Secondly, the lifting device is integrated inside the liftable microphone. If the lifting device fails, only the liftable microphone needs to be mailed for repair or a new liftable microphone needs to be replaced directly. This effectively avoids the problem of having to mail the entire speaker for repair when the lifting device built into the speaker fails, which is common in the prior art, and reduces the burden on users.

[0043] For details, please refer to Figure 2 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.

[0044] In this embodiment, please refer to Figure 2 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 rocker arm 22, and finally inserts into the other shaft hole. A torsion spring 23 is provided on the connecting shaft 24 and is located between the rocker arm 22 and the shaft hole. One end of the torsion spring 23 is inserted into the side of the rocker arm 22. The above arrangement allows the rocker arm 22 to swing, thereby allowing the hook shaft 221 on the rocker arm 22 to engage with the locking groove 32. Furthermore, this design also allows the hook shaft 221 on the rocker arm 22 to disengage from the locking groove 32, and under the action of the torsion spring 23, the hook shaft 221 on the rocker arm 22 returns to its initial position.

[0045] In this embodiment, please refer to Figure 2 and Figure 3The lifting device also includes a guide assembly 4, which is installed inside the base 200. The guide assembly 4 has a guide cavity 41, with the opening end of the guide cavity 41 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 on the one hand, 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.

[0046] 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.

[0047] In this embodiment, please refer to Figure 2 The reset assembly 1 includes a reset spring 11, one end of which is elastically connected to the mounting block 21 and the other end is elastically connected to the guide assembly 4. This arrangement mainly raises and lowers the mounting block 21, 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 compress. This causes the hook shaft 221 on the swing arm 22 to engage with the locking groove 32, at which point the deformation generated by the reset spring 11 becomes stable. When the user presses the microphone body 100 again, the reset spring 11 returns to its original deformation, providing a thrust for the microphone body 100 to detach from the base 200, causing the microphone body 100 to rise, so that the user can hold the microphone body 100.

[0048] For further details, please refer to... Figure 3 and Figure 4 The microphone body 100 has a plurality of first protrusions 101 on the inner wall of the end facing the base 200. The plurality of first protrusions 101 have the same axis. The outer side of the base 200 is provided with second protrusions 201 in conjunction with the first protrusions 101. When the microphone body 100 is inserted into the base 200, the first protrusions 101 are located below the second protrusions 201. The above arrangement allows the first protrusions 101 to slide against the outside of the base 200, thereby allowing the bottom of the microphone body 100 to slide up and down stably on the outside of the base 200.

[0049] In order to limit the sliding range of the first protrusion 101, that is, to limit the sliding distance of the microphone body 100 on the base 200, an annular limiting protrusion 203 is provided on the outer side of the base 200 away from the microphone. The annular limiting protrusion 203 is used to limit the movement of the microphone body 100, that is, to limit the microphone body 100 from continuing to be inserted into the base 200.

[0050] In this embodiment, please refer to Figure 3 and Figure 4 The microphone body 100 has several vertically oriented limiting posts 102 on the inner wall of the end facing the base 200. The limiting posts 102 are arranged in a ring. The outer side of the base 200 has grooves 202 that fit into the corresponding limiting posts 102. The above-mentioned arrangement limits the sliding direction of the microphone body 100 on the base 200. Specifically, it restricts the microphone body 100 to slide only in the vertical direction on the base 200 and prevents it from rotating. This ensures the stable lifting and lowering of the microphone body 100 without any other offset movement that would affect the user's holding of the microphone body 100.

[0051] In fact, 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.

[0052] This utility model also provides a smart speaker, including a speaker body 300 and the aforementioned liftable microphone. The speaker body 300 has a storage cavity 301 for installing the liftable microphone. This arrangement accommodates the microphone inside the speaker. By pressing the liftable microphone, the microphone body 100 can pop out from the storage cavity 301 for the user to hold. The above design accommodates the liftable microphone without using the internal space of the speaker body 300, and also makes the liftable microphone part of the speaker body 300, reducing the risk of the liftable microphone being easily lost.

[0053] 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.
