Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, and in particular to an automatic microphone lifting speaker. Background Technology

[0002] With the increasing popularity of smart speakers, speakers with integrated microphone lifting functions are gradually becoming the mainstream in the market. In existing technologies, microphone lifting mechanisms mostly employ mechanical reciprocating structures, typically using a torsion spring, locking fasteners, and guide slots to retract and raise the microphone. However, this type of structure has significant drawbacks: the locking fasteners frequently impact the guide slots under the action of the torsion spring, resulting in mechanical noise and affecting the user experience; furthermore, it relies on manual operation and lacks automation.

[0003] To address these issues, some existing technologies attempt to employ electric lifting solutions. For example, a motor drives a threaded rotating component and a lifting cylinder to convert rotational motion into linear motion for microphone lifting. However, such solutions rely on frequent forward and reverse switching of the motor to control the lifting process, resulting in high complexity of the drive circuit, increased costs, and susceptibility to electrical interference and motor wear during frequent reversals. Utility Model Content

[0004] The main purpose of this utility model is to provide an automatic microphone lifting speaker, which aims to solve the problems of collision noise generated when the microphone is raised and lowered and the complexity of motor drive control.

[0005] To achieve the above objectives, this utility model proposes an automatic microphone lifting speaker, comprising:

[0006] The speaker body has a storage slot for mounting a microphone;

[0007] A lifting mechanism is installed in the storage slot. The lifting mechanism includes a lifting device and a driving device. The driving device drives the lifting device to slide in the storage slot.

[0008] The lifting device includes a lifting base and a transmission component connected together. The bottom of the microphone is mounted on the lifting base. The driving device includes a driving component and a rotating component. The driving component drives the rotating component to rotate in the forward direction. The rotating component and the transmission component are always in contact and sliding together, so as to drive the transmission component and the lifting base to rise and fall.

[0009] Optionally, the transmission component is provided with a transmission groove, and the edge of the rotating component is always engaged in the transmission groove.

[0010] Optionally, the rotating component includes a turntable and a rotating rod, the turntable being obliquely connected to the rotating rod, and the rotating rod being connected to the driving component to drive the turntable to rotate.

[0011] Optionally, the rotating rod is connected to the center of the turntable, and the projection of the turntable in the vertical direction is circular.

[0012] Optionally, the bottom wall of the storage slot is provided with a rotating groove, and the rotating rod passes through the bottom wall of the rotating groove and rotates within the rotating groove.

[0013] Optionally, the transmission component includes a transmission rod and transmission protrusions. The transmission rod is fixedly connected to the lifting seat, and two transmission protrusions are provided and spaced apart on the transmission rod, with the two transmission protrusions forming the transmission groove at intervals.

[0014] Optionally, the transmission component further includes rollers, which are disposed on the transmission protrusion, and the two rollers roll in contact with the upper and lower surfaces of the turntable.

[0015] Optionally, a partition is provided in the storage slot, the lifting seat slides on the upper side of the partition, the rotating component is provided on the lower side of the partition, and the transmission rod passes through the partition.

[0016] Optionally, the driving component is a motor, which is fixed to the bottom of the storage slot.

[0017] Optionally, the inner wall of the lifting seat is provided with multiple protrusions, which press and engage the microphone.

[0018] The beneficial effects of this invention are as follows: it solves the problems of mechanical collision noise generated during microphone raising and lowering, and the high complexity and increased cost of the drive circuit due to frequent forward and reverse switching of the motor to control the raising and lowering process. By setting a lifting base to fix the microphone inside the sleeve, the lifting base is connected to the transmission component, and the transmission component abuts against the rotating component. This allows the rotating component to drive the transmission component to rise and fall when the drive component controls the rotation of the rotating component, thereby completing the raising and lowering of the microphone. In this process, the drive component does not need to repeatedly switch the drive direction, simplifying the control circuit and reducing costs. Attached Figure Description

[0034] One embodiment of this utility model provides an automatic microphone lifting speaker box, see reference. Figures 1 to 9 The speaker includes a speaker body 1 and a lifting mechanism 2. The speaker body 1 is provided with a storage slot 11 for mounting a pair of microphones 3. The lifting mechanism 2 is installed in the storage slot 11. The lifting mechanism 2 includes a lifting device 21 and a driving device 22. The driving device 22 drives the lifting device 21 to slide in the storage slot 11. The lifting device 21 includes a lifting base 211 and a transmission component 212 connected to each other. The bottom of the microphone 3 is mounted on the lifting base 211. The driving device 22 includes a driving component 221 and a rotating component 222. The driving component 221 rotates in the forward direction. The rotating component 222 and the transmission component 212 are always in contact and sliding to drive the transmission component 212 and the lifting base 211 to rise and fall.

[0035] The automatic lifting speaker enclosure for microphone 3 in this embodiment solves the problems of mechanical collision noise generated during the lifting and lowering of microphone 3 and the high complexity and increased cost of the drive circuit caused by the frequent forward and reverse switching of the motor to control the lifting and lowering process. By setting a lifting seat 211 inside the sleeve to fix microphone 3, the lifting seat 211 is connected to the transmission component 212, and the transmission component 212 abuts against the rotating component 222, so that when the drive component 221 controls the rotation of the rotating component 222, the rotating component 222 can drive the transmission component 212 to rise and fall, thereby completing the lifting and lowering of microphone 3. In this process, the drive component 221 does not need to repeatedly switch the drive direction, simplifying the control circuit and reducing costs.

[0036] Specifically, the speaker body 1 is the outer shell structure of a smart speaker, and a storage slot 11 is provided on its top or side for storing the microphone 3. The bottom of the microphone 3 is provided with a connecting structure to cooperate with the lifting base 211 for fixation. The connecting structure at the bottom of the microphone 3 can be a buckle or a magnetic component.

[0037] After use, microphone 3 is inserted into storage slot 11, positioning it relative to lifting base 211. The drive unit 22 is then activated, driving component 221 to rotate rotating component 222 clockwise. Rotating component 222 engages with transmission component 212, simultaneously converting circumferential rotation into vertical descent, causing lifting base 211 to move microphone 3 downwards, thus fully retracting it into storage slot 11. When needed, the drive unit 22 is activated again, driving component 221 to continue rotating rotating component 222 clockwise. Rotating component 222 continues circumferential rotation, simultaneously converting circumferential rotation into vertical descent, causing lifting base 211 to move microphone 3 upwards. Microphone 3 extends out of storage slot 11 for user removal. During the microphone 3's lifting and retraction process, drive component 221 only needs to rotate in one direction to complete the lifting and lowering of microphone 3, eliminating the need to repeatedly switch the drive direction of drive component 221, thereby simplifying the control circuit and reducing costs.

[0038] Furthermore, the transmission component 212 is provided with a transmission groove 2124, and the edge of the rotating component 222 is always engaged in the transmission groove 2124. In this embodiment, the transmission groove 2124 is formed on the side of the transmission component 212. During rotation, the edge of the rotating component 222 slides relative to each other within the transmission groove 2124. Since the height of different positions on the circumferential edge of the rotating component 222 is different, the position of the edge of the rotating component 222 engaged in the transmission groove 2124 is also at different heights during rotation, thereby driving the transmission component 212 to move up and down. It can be understood that the shape of the transmission groove 2124 is not limited. For example, the transmission groove 2124 can be a notch structure formed on the transmission component 212 or a protrusion formed by intervals on the transmission component 212, as long as it can ensure that the rotating component 222 is always engaged in the transmission groove 2124.

[0039] Further, the rotating component 222 includes a turntable 2221 and a rotating rod 2222. The turntable 2221 is inclinedly connected to the rotating rod 2222, and the rotating rod 2222 is connected to the driving component 221 to drive the turntable 2221 to rotate. In this embodiment, the turntable 2221 and the rotating rod 2222 are integrally connected, and the other end of the rotating rod 2222 is connected to the driving end of the driving component 221. When the driving component 221 is activated, it drives the turntable 2221 to rotate in the forward direction. The inclined design of the turntable 2221 allows it to continuously abut against the transmission component 212 during rotation, switching the position height of the turntable 2221 against the transmission component 212, thereby converting the rotational motion of the turntable 2221 into the lifting motion of the transmission component 212.

[0040] Furthermore, the rotating rod 2222 is connected to the center of the turntable 2221, and the projection of the turntable 2221 in the vertical direction is circular. In this embodiment, the rotating rod 2222 extends vertically and is connected to the center of the turntable 2221, so that the turntable 2221 and the rotating rod 2222 rotate synchronously around the central axis of the rotating rod 2222. In the vertical direction, the projection of the turntable 2221 is circular, so that the horizontal distance from the center of the turntable 2221 to all points on the edge of the turntable 2221 is the same, so that when the turntable 2221 rotates around its center point, the distance from all points on the edge of the turntable 2221 to the transmission member 212 is equal, and the turntable 2221 can be fully engaged in the transmission groove 2124. It should be noted that, provided that the dimensions of the transmission groove 2124 meet the requirements, the projection of the turntable 2221 in the vertical direction can also be other shapes, such as an ellipse or a near-circular polygon, to ensure that the edge of the turntable 2221 does not detach from the transmission groove 2124.

[0041] Furthermore, the bottom wall of the storage groove 11 is provided with a rotating groove 12, and the rotating rod 2222 passes through the bottom wall of the rotating groove 12 and rotates within the rotating groove 12. In this embodiment, the driving member 221 is fixed to the outer side wall of the lower end of the storage groove 11, and the rotating rod 2222 is connected to the driving member 221 and passes through the bottom wall of the storage groove 11, so that part of the structure of the rotating rod 2222 is located within the rotating groove 12, and the side wall of the rotating groove 12 surrounds the rotating rod 2222, thereby preventing the rotating rod 2222 from swaying left and right and improving the stability of the transmission of the rotating rod 2222.

[0042] Further, the transmission component 212 includes a transmission rod 2121 and transmission protrusions 2122. The transmission rod 2121 is fixedly connected to the lifting seat 211. Two transmission protrusions 2122 are provided and spaced apart on the transmission rod 2121, forming the transmission groove 2124. In this embodiment, one end of the transmission rod 2121 is fixedly connected to the bottom of the lifting seat 211, and the other end of the transmission rod 2121 is suspended. The transmission protrusions 2122 are spaced apart on the side of the transmission rod 2121 in the vertical direction, so that the edge of the turntable 2221 extends into the transmission groove 2124 through the opening on the side of the transmission groove 2124.

[0043] refer to Figures 6 to 9In the initial state, the edge of the turntable 2221 at the high point is engaged in the transmission groove 2124, and the microphone 3 is stored in the storage groove 11. The control drive 221 is activated, and the turntable 2221 rotates. Specifically, it can rotate 180 degrees so that the edge of the turntable 2221 at the high point gradually slides out of the transmission groove 2124, and the edge of the turntable 2221 at the low point gradually slides into the transmission groove 2124. This causes the lower side of the turntable 2221 to press against the transmission protrusion 2122 located on the lower side, causing the transmission rod 2121 to slide downward, thereby driving the microphone 3 to move downward and turning off the drive 221. When microphone 3 needs to be removed, the drive unit 221 is activated again. The drive unit 221 continues to rotate in the same direction, specifically by 180 degrees. Similarly, the edge of the highest point of the turntable 2221 gradually slides into the transmission groove 2124. The upper side of the turntable 2221 presses against the upper transmission protrusion 2122, causing the transmission rod 2121 to move upward, thus extending microphone 3 out of the storage slot 11. Throughout the process, the drive unit 221 only needs to rotate in one direction to complete the raising and lowering of microphone 3, without needing to switch the rotation direction, simplifying the control logic.

[0044] Furthermore, the transmission component 212 also includes rollers 2123, which are disposed on the transmission protrusion 2122. The two rollers 2123 roll in contact with the upper and lower surfaces of the turntable 2221. The design of the rollers 2123 reduces the friction between the turntable 2221 and the transmission protrusion 2122. During the lifting and lowering process, the rollers 2123 roll along the upper or lower side of the turntable 2221 to replace the frictional sliding of the transmission protrusion 2122, making the lifting and lowering transmission process smoother and reducing noise.

[0045] Furthermore, a partition 13 is provided within the storage slot 11, the lifting seat 211 slides on the upper side of the partition 13, the rotating component 222 is disposed on the lower side of the partition 13, and the transmission rod 2121 passes through the partition 13. The partition 13 divides the storage slot 11 into upper and lower spaces. The upper part is used for the lifting and storage of the microphone 3, and the lower part is used for the installation of the turntable 2221 and the rotating rod 2222, thereby improving the compactness and stability of the structure. It can be understood that the partition 13 is provided with a through hole for the transmission rod 2121 to pass through, so as to ensure the stability of the transmission rod 2121. In other embodiments, the sidewall of the through hole on the partition 13 can also be extended to provide a guide structure, such as a groove and a slider, to further restrict the movement direction of the transmission rod 2121 and prevent it from deviating during lifting.

[0046] Furthermore, the driving component 221 is a motor, which is fixed to the bottom of the storage slot 11. The driving component 221 is a stepper motor, and its speed and rotation angle can be precisely adjusted by the control circuit to achieve precise control of the microphone 3's lifting and lowering. Specifically, the driving component 221 drives the rotation of one revolution to control the turntable 2221 to rotate one revolution, thereby enabling the microphone 3 to complete the process of rising and falling.

[0047] Furthermore, the inner wall of the lifting base 211 is provided with multiple protrusions 2111, which press and engage the microphone 3. In this embodiment, the lifting base 211 has a cylindrical structure with multiple protrusions 2111 on its inner wall for pressing and engaging the microphone 3, ensuring that the microphone 3 will not loosen or fall off during lifting. The protrusions 2111 are made of elastic material, such as rubber or silicone, which can firmly fix the microphone 3 without damaging its surface. It is understood that the method of fixing the lifting base 211 to the microphone 3 is not limited; for example, the two can also be connected by magnetic attraction or a locking mechanism.

[0048] The bottom of the lifting base 211 is also equipped with a charging terminal 14, which is connected to the power supply inside the speaker body 1. The bottom of the microphone 3 is equipped with a charging contact. When the microphone 3 is fully retracted, the charging terminal 14 contacts the charging contact to achieve automatic charging. It should be noted that the microphone and the lifting base can also be wirelessly charged through a receiving coil and a transmitting coil.

[0049] 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.
