[0048] An embodiment of the present invention provides an active lifting microphone, referring to Figure 1 and Figure 2 ,include:

[0049] Microphone body 11;

[0050] A base 12, on which the microphone body 11 is slidably plugged;

[0051] A lifting device is provided 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 .

[0052] In the prior art, when the microphone 1 is stored, it is usually inserted into a storage cavity. After the microphone 1 is inserted into the storage cavity, its top is lower than the opening of the storage cavity or flush with the opening of the storage cavity. When the user takes out the microphone 1, the user needs to use a lifting mechanism to lift the microphone 1 so that its top extends out of the opening of the storage cavity to facilitate the removal of the microphone 1. In this embodiment, a lifting device is integrated in the microphone 1 itself, and the microphone 1 is actively lifted by the lifting device to facilitate the removal of the microphone 1. The need to additionally add a lifting mechanism in the prior art is eliminated, the structure is simpler, the cost is lower, and space waste is avoided.

[0053] It should be noted that the lifting device in this embodiment can adopt an electric lifting device. Specifically, a driving cylinder can be installed between the microphone body 11 and the base 12. The driving 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, and realizing the removal and storage of the microphone 1; further, a motor screw linear drive module in the existing technology can be installed between the microphone body 11 and the base 12, and the motor drives the screw to rotate forward or reverse, driving the nut on the screw to move up and down along the screw. After the microphone body 11 is connected to the nut, the microphone body 11 can be driven by the nut to move up and down, thereby adjusting the distance between the microphone body 11 and the base 12, and realizing the removal and storage of the microphone 1.

[0054] Furthermore, a control element for driving the cylinder or motor to start or shut down can be integrated on the microphone body 11. Specifically, the control element can adopt a touch sensor in the prior art. The user presses or touches the touch sensor so that the touch sensor receives an on or off signal, and then the main control board of the microphone 1 controls the start or shut down of the driving cylinder or motor to adjust the distance between the microphone body 11 and the base 12, thereby realizing the removal and storage of the microphone 1.

[0055] Furthermore, the lifting device in this embodiment can adopt a manual lifting method. Specifically, the lifting device includes:

[0056] A reset component, the two ends of which are respectively connected to the microphone body 11 and the base 12;

[0057] A pop-up assembly is arranged on the side of the reset assembly, and the two ends of the pop-up assembly are respectively connected to the microphone body 11 and the base 12. The pop-up assembly has a locked state and an unlocked state. When the pop-up assembly is in the locked state, the microphone body 11 is fixed to the base 12. When the pop-up assembly is in the unlocked state, the microphone body 11 can slide along the base 12.

[0058] In this embodiment, the reset component adopts an elastic member 131. Through the cooperation of the reset component and the pop-up component, the microphone body 11 can be manually raised and lowered. The user only needs to press the pop-up component to switch the locking and unlocking states of the pop-up component. Under the action of the elastic force of the elastic member 131, the microphone body 11 is driven to rise and fall, completing the removal and storage of the microphone 1.

[0059] Specifically, in this embodiment, the microphone 1 is stored in the storage cavity. Figure 1As shown, the microphone 1 is in the initial state, the pop-up assembly is in the locked state, the microphone body 11 is not raised, and the microphone body 11 is fixed to the base 12; when the microphone 1 needs to be taken out, 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 pop-up assembly is unlocked and converted from the locked state to the unlocked state, thereby, referring to Figure 2 , the microphone body 11 slides toward the end away from the base 12, the microphone 1 is lifted as a whole, and the top of the microphone 1 exceeds the opening of the storage cavity, making it easier for the user to take out the microphone 1. It should be noted that Figure 2 The expanded length of the microphone 1 is only an example, and its expanded length can be adjusted according to actual needs.

[0060] Further, refer to Figure 3 and Figure 4 , the spring-lift assembly includes:

[0061] A clamping member 132 rotatably mounted on the microphone body 11 ;

[0062] A guide groove 133 is formed on the base 12 along the lifting direction of the microphone 1, and the clamping member 132 is slidably connected to the guide groove 133;

[0063] There are a locked state and an unlocked state between the clamping member 132 and the guide groove 133; when the clamping member 132 and the guide groove 133 are in the locked state, the microphone body 11 is fixed to the base 12, and when the clamping member 132 and the guide groove 133 are in the unlocked state, the microphone body 11 can slide along the base 12.

[0064] In this embodiment, the structure of the elastic member 131, the clamping member 132 and the guide groove 133 can realize the switching of the locked state and the unlocked state of the pop-up assembly. The structure is simple, the operation is convenient, and the space occupation is small. It can avoid the microphone 1 from being too large. At the same time, it avoids the problem of normal lifting due to circuit failure when the electric lifting method is used in the existing technology, thereby ensuring the stability of the lifting.

[0065] Specifically, after the microphone 1 is stored in the storage cavity, at this time, Figure 1As shown, the microphone 1 is in an initial state, the clamping member 132 and the guide groove 133 are in a locked state, the microphone body 11 is not raised, the elastic member 131 is compressed, and the microphone body 11 is fixed to the base 12; when the microphone 1 needs to be taken out, 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 clamping member 132 will slide and rotate in the guide groove 133, so that the clamping member 132 and the guide groove 133 are unlocked, and the state is changed from the locked state to the unlocked state. At this time, the elastic restoring force of the elastic member 131 will be applied between the microphone body 11 and the base 12, so that the microphone body 11 receives the elastic force of the elastic member 131, refer to Figure 2 , the microphone body 11 slides toward the end away from the base 12. During this process, the clamping member 132 slides along the guide groove 133, raising the microphone 1 as a whole, with the top of the microphone 1 extending beyond the opening of the storage cavity, making it easier for the user to remove the microphone 1. Compared to existing lifting mechanisms, the pop-up assembly in this embodiment has a simpler structural design. The locking and unlocking states of the pop-up assembly can be switched by sliding and rotating the clamping member 132 within the guide groove 133. The user only needs to press the end of the microphone body 11, which is very simple to operate, has lower costs, takes up less space, and is conveniently integrated into the microphone 1.

[0066] Further, refer to Figure 6 , the guide groove 133 includes a first groove portion 1331 and a second groove portion 1332;

[0067] When the clamping member 132 is located in the first groove 1331 , the clamping member 132 can rotate in the first groove 1331 to achieve a state switch between the clamping member 132 and the guide groove 133 ;

[0068] When the fastening member 132 is located in the second groove 1332 , the fastening member 132 can slide in the second groove 1332 to enable the microphone body 11 to slide along the base 12 .

[0069] In this embodiment, the first groove portion 1331 and the second groove portion 1332 are distributed along the sliding direction of the microphone body 11, and in the sliding direction of the microphone body 11, the first groove portion 1331 is located below the second groove portion 1332, the clamping piece 132 can slide in the second groove portion 1332, slide and rotate in the first groove portion 1331. Specifically, in the initial state, when the clamping piece 132 is not locked with the guide groove 133, the microphone body 11 is moved away from the base 12 under the elastic force of the elastic member 131 at both ends, so that the clamping piece 132 slides to the top end of the second groove portion 1332; when the user presses the microphone body 11, the microphone body 11 slides towards the base 12, and the clamping piece 132 slides into the first groove portion 1331 along the second groove portion 1332, and then rotates to realize the locking between the clamping piece 132 and the guide groove 133, at this time, the elastic member 131 is compressed; when unlocking is needed, the user presses the end of the microphone body 11 again, so that the clamping piece 132 continues to rotate in the first groove portion 1331, realizes the unlocking between the clamping piece 132 and the guide groove 133, and after the clamping piece 132 and the guide groove 133 are unlocked, the microphone body 11 is lifted up under the elastic restoring force of the elastic member 131, the clamping piece 132 slides from the first groove portion 1331 to the second groove portion 1332, and returns to the initial position at the top end of the second groove portion 1332, completing the lifting of the microphone body 11, which is convenient for the user to take out the microphone 1.

[0070] Further, with reference to Figure 5 , the first end of the clamping piece 132 is rotationally connected with the microphone body 11, and the second end of the clamping piece 132 is sequentially provided with a first abutting portion 1321, a second abutting portion 1322, a third abutting portion 1323 and a fourth abutting portion 1324 in the rotation direction thereof;

[0071] The first abutting portion 1321 and the second abutting portion 1322 form a first abutting surface 1325 therebetween, and the third abutting portion 1323 and the fourth abutting portion 1324 form a second abutting surface 1326 therebetween, and the first abutting surface 1325 is parallel to the second abutting surface 1326.

[0072] Further, with reference to Figure 6, the first slot portion 1331 includes a first side wall 13311, a second side wall 13312, a third side wall 13313, a fourth side wall 13314, a fifth side wall 13315, a sixth side wall 13316, and a seventh side wall 13317, a first corner 13318 is formed between the second side wall 13312 and the third side wall 13313, and a second corner 13319 is formed between the sixth side wall 13316 and the seventh side wall 13317, when the clamping piece 132 is in a locked state with the guide slot 133, the first abutting portion 1321 abuts against the seventh side wall 13317, the second abutting portion 1322 abuts against the first side wall 13311, and the fourth abutting portion 1324 abuts against the fifth side wall 13315.

[0073] In this embodiment, the abutting portions, the abutting surfaces of the clamping piece 132 abut against the side walls and the corners of the first slot portion 1331 and the second slot portion 1332 to achieve the sliding and rotating of the clamping piece 132, and to complete the locking and unlocking between the clamping piece 132 and the guide slot 133. Specifically, refer to Figures 7 to 17 , the movement process between the clamping piece 132 and the guide slot 133 and the switching between the locked and unlocked states are described in detail.

[0074] Refer to Figure 7 , the clamping piece 132 is not locked with the guide slot 133, and the clamping piece 132 is lifted to the first end away from the base 12 under the elastic force of the elastic member 131, and the clamping piece 132 is located at the top end of the second slot portion 1332. At this time, the microphone 1 is stored in the storage cavity, and the top end of the microphone 1 exceeds the opening of the storage cavity, and the microphone 1 is not completely stored;

[0075] When it is necessary to completely store the microphone 1 in the storage cavity, it is necessary to completely press the microphone body 11 into the storage cavity. At this time, the user needs to press the end portion of the microphone body 11. In this process, refer to Figure 8 , the microphone 1 slides downward along the second slot portion 1332 into the first slot portion 1331, and the elastic member 131 is compressed during the downward sliding of the microphone body 11; refer to Figure 9 and Figure 10 , when the microphone 1 slides at the junction of the first slot portion 1331 and the second slot portion 1332, the first abutting surface 1325 formed between the first abutting portion 1321 and the second abutting portion 1322 abuts against the second corner 13319, so that the clamping piece 132 is driven to rotate counterclockwise during the sliding of the clamping piece 132 from the second slot portion 1332 to the first slot portion 1331. Refer to Figure 11When the clamping part 132 moves to the bottom of the first slot 1331, the second abutting surface 1326 abuts against the first corner 13318, at this moment, the clamping part 132 can no longer continue to move downward, the user's hand used to press the microphone body 11 downward feels a repulsive force, receives a signal that the microphone body 11 is pressed into place, and then releases the hand. After the user releases the hand, the microphone body 11 rises under the elastic restoring force of the elastic member 131, and since the second abutting surface 1326 abuts against the first corner 13318 and the fourth abutting part 1324 abuts against the fourth side wall 13314, the clamping part 132 continues to rotate counterclockwise during the rising process, as shown in Figure 12 .

In the embodiment, the first convex edge 122 and the second convex edge 113 are arranged in a ring shape along the outer periphery of the base 12 and the microphone main body 11 respectively. In this way, the outer edge of the first convex edge 122 or the second convex edge 113 can be chamfered, so that the first convex edge 122 and the second convex edge 113 are clamped together in a certain direction.

[0081] An embodiment of the utility model discloses an intelligent sound box, refer to Figure 18 , including sound box main body 41, sound box main body 41 is set up with the storage groove 42 for installing any above-mentioned microphone 1. Since the intelligent sound box 4 proposed in the embodiment includes all the schemes of all the storage structures described above, it at least has the same technical effect as the storage structure, which will not be described here.

[0082] In some embodiments, the storage groove 42 can be a cavity for accommodating the microphone 1. Specifically, in the embodiment, the storage groove 42 is formed on the storage assembly, and the depth of the storage groove 42 is greater than or equal to the length of the microphone 1. The storage groove 42 includes an entrance, through which the microphone 1 can be vertically or horizontally inserted into the storage groove 42 to achieve plug-in storage. The microphone 1 fixing structure can be arranged inside or outside the entrance to fix the microphone 1 after storage. The entrance can be arranged at any position of the intelligent sound box 4, including the top surface, side surface and bottom surface of the intelligent sound box 4.

[0083] In some embodiments, the intelligent sound box 4 can be provided with a screen, and can also be provided with a movable structure and a screen storage groove 42. The screen can be closed by the movable structure, so that the screen is stored in the screen storage groove 42. The microphone 1 storage groove 42 can be arranged below the screen, and the microphone 1 is completely stored in the intelligent sound box 4 after the screen is closed.

[0084] Further, the sound box main body 41 is provided with a jacking mechanism for ejecting the microphone 1 from the storage groove 42. The jacking mechanism can adopt a mechanical lifting mechanism in the prior art, or an electric lifting mechanism. In cooperation with the elastic lifting assembly of the microphone 1, when the jacking mechanism fails or is powered off, the user can take out the microphone 1 from the sound box main body 41 through the elastic lifting assembly.

[0085] Furthermore, the speaker body 41 is also provided with a sensing element for sensing the insertion of the microphone 1 into the storage slot 42. It should be noted that when the microphone 1 is connected to the smart speaker 4, it will cause a howling sound if it is too close to the smart speaker 4. The smart speaker 4 emits a harsh howling sound, which greatly affects the user experience. In particular, when the smart speaker 4 stores the microphone 1, the collision and friction sounds between the microphone 1 and the smart speaker 4 during the storage process are more likely to cause howling. Based on this, the microphone 1 can be automatically shut down when it is close to the smart speaker 4 to prevent the microphone 1 from howling when it is close to the smart speaker 4 or when the smart speaker 4 stores the microphone 1.

[0086] In some embodiments, in order to prevent the microphone 1 from howling when it is close to the smart speaker 4 or when the smart speaker 4 receives the microphone 1, the microphone 1 can be automatically shut down when it is close to the smart speaker 4. Specifically, a sensing element can be set on the microphone 1 and / or the smart speaker 4, and the sensing element can be used to sense the distance between the smart speaker 4 and the microphone 1, and generate a corresponding sensing signal after the distance between the smart speaker 4 and the microphone 1 is less than or equal to a preset distance, and send the sensing signal to the control device of the microphone 1, or send the sensing signal to the control device of the microphone 1 through the smart speaker 4, so that the control device controls the microphone 1 to shut down. More specifically, the sensing element can be one or more, which can be a Hall element, a distance sensor, an infrared sensor, and any other single electronic component that can sense the distance between the smart speaker 4 and the microphone 1, as well as any combination of electronic components.

[0087] In some specific embodiments, when the microphone 1 storage structure is a cavity, a sensing element can be positioned at the entrance of the storage slot 42. When the microphone 1 is inserted into the storage slot 42, the sensing element can generate a corresponding sensing signal immediately after the microphone 1 is inserted, thereby shutting down the microphone 1. Alternatively, the sensing element can be positioned at an end of the storage slot 42 away from the entrance. Similarly, a corresponding sensing signal can be generated when the microphone 1 is inserted near the sensing element, shutting down the microphone 1. This can also prevent the sensing element from being exposed to the outside due to the entrance facing outward, which could lead to degradation of the component.

[0088] In some more specific embodiments, the sensing element is a Hall effect element and a magnetic element, which are respectively disposed at corresponding positions on the smart speaker 4 and the microphone 1. For example, the magnetic element is disposed at the corresponding position of the microphone 1 and the Hall effect element is disposed at the corresponding position of the smart speaker 4, or the Hall effect element is disposed at the corresponding position of the microphone 1 and the magnetic element is disposed at the corresponding position of the smart speaker 4. The triggering condition of the Hall effect element may 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 4 and the microphone 1 is sufficient to cause howling, and the microphone 1 needs to be turned off.

[0089] In some preferred embodiments, a magnetic element is provided at the corresponding position of microphone 1, and a Hall effect element is provided at the corresponding position of smart speaker 4. Since users carry microphone 1 with them while singing karaoke, they may move to other places with strong magnetic fields. If a Hall effect element is provided on microphone 1, it may cause microphone 1 to shut down incorrectly, thus affecting the user experience. If the microphone 1 storage structure is a cavity, that is, the microphone 1 is inserted into the storage, the Hall effect element can be provided at the entrance of the storage slot 42 of the smart speaker 4 or at the end away from the entrance.

[0090] In other more specific embodiments, the sensing elements are Hall elements and charging elements, and the charging element includes a charging structure and a power receiving structure. The smart speaker 4 is provided with a charging structure, and the microphone 1 is provided with a power receiving structure. It should be understood that when the charging structure and the power receiving structure abut, there will be a magnetic field change. Based on this, the trigger condition of the Hall element can be set to detect the magnetic field change. When the Hall element detects a magnetic field change, it means that the charging structure of the smart speaker 4 is abutting the power receiving structure of the microphone 1. At this time, the distance between the smart speaker 4 and the microphone 1 is sufficient to cause howling, and the microphone 1 needs to be shut down. Specifically, the charging structure can be set on the surface of the smart speaker 4, or it can be set corresponding to the storage structure. When the storage structure of the microphone 1 is a storage slot 42, that is, when the microphone 1 is plug-in storage, the charging structure is set at the end of the storage slot 42 of the smart speaker 4 away from the entrance, and the power receiving structure is set correspondingly at the bottom or bottom surface of the end of the microphone 1. The Hall element can be set near the charging structure so that the Hall element can sense the magnetic field change caused by the power-on moment.

[0091] In some more specific embodiments, the sensing element is a Hall effect element and a charging element. The charging element includes a charging structure and a power receiving structure. The smart speaker 4 is provided with the charging structure, and the microphone 1 is provided with the power receiving structure. In addition, the smart speaker 4 and the microphone 1 may also be provided with a magnetic member. The magnetic member is located outside the sensing trigger range of the Hall effect element and is used to fix the microphone 1 rather than trigger the Hall effect element.

All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
