The control unit 23 is connected to the driving motor 21, and the driving motor 21 is connected to the screw 22. The control unit 23 can intelligently control the start and stop and forward or reverse rotation of the driving motor 21, thereby driving the screw 22 to move back and forth along the axial direction of the telescopic handle, and can intelligently control the movement length of the screw 22.

[0034] Preferably, the control unit 23 includes a circuit board assembly 231 and a sensing module 232. The circuit board assembly 231 is connected to the telescopic module 1, and is electrically connected to the sensing module 232 and the drive motor 21, respectively. The sensing module 232 senses external environmental data and calculates the external environmental data through a program, analyzes and judges the calculation results, and controls the number and direction of rotation of the drive motor 21 through the circuit board assembly 231, thereby controlling the length and direction of movement of the screw 22.

[0035] Preferably, the sensing module 232 includes at least one of a gravity sensing module 2311 , a pressure sensing module 2322 and a temperature sensing module 2333 , but does not only include these automatic sensing scene modules.

[0037] Preferably, the control unit 23 also includes a voice control module 2344, which is used to receive the voice command of the identified person to control the start or stop of the driving module 2; the control programs of the gravity sensing module 2311, the pressure sensing module 2322, the temperature sensing module 2333 and the voice control module 2344 can be integrated in the same or multiple chips, electrically connected to or arranged together with the circuit board assembly 231, and jointly arranged on the circuit board bracket 13.

[0038] like Figure 2The above is a schematic diagram of the appearance structure of the telescopic module 1 of the telescopic handle, wherein the telescopic module 1 includes a fixed shell 10 and a movable shell 11, and a sensing member 14 is further provided on the surface of the movable shell 11. The fixed shell 10 and the movable shell 11 are connected and can slide with each other. A mounting hole may also be formed on the outside of the movable shell 11, and the sensing member 14 may be provided in the mounting hole. The sensing member 14 is used to sense external parameters such as pressure, temperature, and light received on the surface of the telescopic module 1, and transmit these parameters to the sensing module 232 of the control unit 23. The sensing member 14 and the sensing module 232 may be connected by electrical connection and / or other means such as spring sheets.

[0039] A sound pickup structure 3 commonly required for a microphone is arranged inside the movable housing 11 , thereby forming an adaptive telescopic microphone with automatic sensing. The sound pickup structure 3 is fixedly connected to the dustproof shell 112 and electrically connected to the circuit board assembly 231 .

[0040] like Figure 6 As shown, it is a schematic diagram of the structure of the microphone with a telescopic handle in the shortened state. When the microphone needs to be extended or retracted, the sensing element 14 is pressed to trigger the control unit 23, which can realize the forward or reverse rotation of the driving motor 41, and drive the lead screw 42 to move in opposite directions along the radial direction of the fixed shell 10, thereby driving the circuit board bracket 13 to move forward or reversely, and the telescopic module 1 as a whole can be controlled to make forward or reverse translational movement along the axial direction of the fixed shell 10, thereby realizing the contraction effect of the microphone.

[0041] Optional, such as Figure 7 As shown, the driving module 2 may further include a nut 24, a lead screw 22 fixed on the bottom shell 101, the nut 24 is electrically connected to the driving motor 21, the driving motor 21 and the nut 24 are fixed on the slider 14 as a whole, the driving motor 21 drives the nut 24 to rotate, and drives the telescopic module 1 to translate as a whole, the automatic telescopic structure is driven by the nut 24, can achieve self-locking, and runs smoothly.

[0042] Optionally, the transmission between the driving motor 21 and the lead screw 22 may also be a gear rack, a crank connecting rod or other structural parts, driving the telescopic module 1 to perform translational movement as a whole.

[0043] Optional, such as Figure 8As shown, it is a schematic diagram of the system control logic of the microphone. For different user groups, such as adults and children who need to use the microphone, the control unit 23 can adaptively control the number of rotations of the drive motor 21 to achieve the change in the length of the microphone, allowing the user to choose the most comfortable length state; at this time, the user can use voice control, such as "microphone pop-up", or issue instructions through gesture sensing, virtual buttons or physical buttons; at this time, the control unit 23 receives the instruction and determines whether the microphone trigger condition is met. If so, the drive motor 21 is controlled to rotate forward or reverse, and the drive module 2 drives the telescopic module 1 to make a translational motion along the length direction to achieve the extension or contraction of the microphone, which is convenient for the user to pick up.

[0044] Optionally, the control unit 23 can also determine the pressure or temperature to control the contraction function of the microphone according to the size of the palm and the grip strength; for example, when a person holds the microphone, the pressure sensing module 2322 and the temperature sensing module 2333 of the control unit 23, combined with the external data collected by the sensing component 14, determine and calculate the number of turns that the drive motor 21 needs to make, thereby controlling the lead screw 22 of the drive module 2 to move a certain distance, thereby enabling the microphone to automatically adapt to different user groups and other usage scenarios.

[0045] The specific process is as follows Figure 8 As shown:

[0046] S101, receiving user instructions:

[0047] Receiving user instructions includes extension instructions or contraction instructions. When the extension length of the microphone does not meet the user's comfort level, the user can input extension or contraction instructions to the microphone through voice, gesture sensing, virtual buttons or physical buttons. The user instructions may also include extension parameters.

[0048] S102, obtaining instruction parameters and / or environmental parameters according to user instructions:

[0049] After receiving the user's instructions, if the user directly inputs instructions or parameters through voice, the voice control module 2344 directly obtains the instructions and / or parameters input by the user's voice; if the user directly grasps the fixed shell of the microphone through physical buttons, virtual buttons or palms, the control unit 23 recognizes the button instructions through the gravity sensing module 2311, the pressure sensing module 2322 or the temperature sensing module 2333, or combines infrared sensing / pressure sensors to obtain parameter values ​​such as thermal values / pressure values, and judges the extension and retraction instructions and the distance required to be extended and retracted.

[0050] S103, controlling the driving motor to complete driving according to the instruction parameters and / or environmental parameters:

[0051] After obtaining the instruction parameters and / or environmental parameters, the control unit 23 controls the driving module 2 to start, and triggers the driving motor 21 to rotate forward or reverse and the number of revolutions according to the parameters, driving the telescopic module 1 to extend or compress it by a specific distance, thereby completing the extension and retraction of the microphone.

[0052] Optionally, when the microphone falls, the gravity sensing module 2311 of the control unit 23 cooperates with devices such as gyroscopes, springs and gravity sensors to obtain external environment data and data such as the direction and acceleration of the microphone falling. The control unit 23 determines whether it is necessary to enable the automatic retraction function of the microphone by judging the magnitude of the acceleration change when the microphone falls. If the acceleration change reaches a set threshold, the control unit 23 controls the start of the drive motor 21 to retract the microphone in the direction of reducing acceleration. When the microphone is hit by external force or the microphone is subjected to force in the length direction, the automatic retraction of the microphone can play a certain buffering role, which can reduce the risk of the microphone being damaged.

[0053] The specific judgment logic is shown in Figure 9:

[0054] S201, determining the contraction / extension state of the microphone:

[0055] When the microphone falls, the control unit 23 determines the extension length and state of the microphone itself.

[0056] S202, collecting microphone position parameters or environmental parameters:

[0057] At the same time, the control unit 23 collects the position parameters and environmental parameters of the microphone during the falling process through the gravity sensing module 2311. The environmental parameters include the falling direction, falling time, falling speed, falling acceleration, etc. of the microphone, and determines whether the falling acceleration reaches the threshold.

[0058] S203, controlling the driving direction and driving parameters of the driving module to achieve extension / contraction of the microphone:

[0059] The control unit 23 combines with the gravity sensing module 2311 to collect parameters such as the microphone falling direction, falling time, falling speed, and falling acceleration, and performs rapid calculations at the same time to calculate the rotation direction and specific number of rotations of the drive motor 21. The drive motor 21 drives the lead screw 22 to drive the telescopic module 1 to move in the direction of reducing acceleration, and move an appropriate distance to achieve the extension or contraction of the microphone, ultimately achieving an anti-fall effect.
