In connection with the preferred embodiment shown in fig. 1, the fastening means may be fastened to the pointing device or to the microphone stand. When the microphone is suspended in the suspension member 21, downward pressure is applied to the suspension member 21 due to the self weight of the microphone, so that the suspension member 21 moves downward; meanwhile, the elastic member 3 is compressed or stretched when the suspension member 21 moves downward, and the downward gravitational potential energy is converted into elastic potential energy to be stored; the downward movement of the inductive counterpart 22 with the suspension member 21 causes a change in the inductive signal of the inductor switch 13, which is related to the control switch signal of the microphone, so that the microphone is disconnected from the electrical signal circuit, and thus the microphone is suspended in the suspension member 21, and the power supply or signal connection is automatically disconnected to turn off the sound amplification function; the service time of the microphone can be prolonged, and noise signals can not be generated to influence users; when the microphone is taken out of the hanging part 21, the hanging part 21 loses the self-weight pressure of the microphone, the elastic potential energy stored in the elastic element 3 is released, the hanging part 21 is pushed or pulled to move upwards to reset, and the elastic potential energy of the elastic element 3 is converted into the gravitational potential energy of the hanging part 21; the induction matching part 22 moves upwards along with the hanging part 21 to reset, and the induction signal of the inductor switch 13 changes to control the microphone to close an electric signal circuit, so that the microphone recovers the functions of amplifying and the like without influencing the use of a user. The microphone induction hanging frame can timely sense whether the microphone is hung in the hanging piece 21 or not, and on the premise of not influencing the use of a user, the microphone electric signals are cut off so as to prolong the use time of the microphone and avoid noise interference when the microphone is not used.
In the preferred embodiment shown in fig. 1, the fixing device is provided with a plurality of vertical guide rods 11, and each guide rod 11 is sleeved with the elastic part 3; the fixed end of the elastic piece 3 is fixed on the fixing device, and the telescopic end is fixed on the moving device. The elastic part 3 is clamped between the fixing device and the moving device and sleeved on the guide rod 11, so that when the suspension part 21 drives the elastic part 3 to move, the elastic part 3 deforms along the direction of the guide rod 11 and stores elastic potential energy, and the elastic potential energy is released along the direction of the guide rod 11 to reset the suspension part 11, thereby ensuring the deformation direction of the elastic part 3 and the moving direction of the suspension part 21, and avoiding the problem that the movement of the suspension part 21 is blocked due to the deflection of the elastic part 3. The elastic member 3 may be a compression member compressed by a force or a tension member stretched by a force.
In order to ensure stable movement and save manufacturing cost, the two guide rods 11 are preferably selected, the upper ends and the lower ends of the two guide rods are respectively fixed on the inner sides of the fixing devices, and the middle parts of the fixing devices are provided with baffle plates 12; the elastic part 3 is a compression spring, and the fixed end of the lower part of the compression spring is fixed on the baffle 12; the moving device comprises a main sliding block 23 with a step hole arranged inside, two guide rods 11 respectively penetrate through the step hole, and a telescopic end at the upper part of the compression spring extends into the step hole and is abutted against the step of the step hole; the inductor matching piece 22 is fixed in the middle of the inner side of the main sliding block 23 and is opposite to the inductor switch 13; the main slider 23 may be fixed to the hanger 21 by a link 25. As shown in fig. 4, which shows an exploded view of the fixing structure of the embodiment, the main slider 23 is in a quadrangular prism shape, and the connecting member 25 penetrates through the induction-coupling member 22 and the main slider 23 and is inserted into the fixing pin 26 at the side of the hanger 21 to fix the induction-coupling member 22 and the main slider 23 to the moving device. In order to distribute the stress of the main slider 23 and make it slide more smoothly, the main slider 23 may be a horizontally fixed elongated shape and fixed to the side of the hanger 21 by a plurality of connecting members 25. In the structure, the guide rod 11 is positioned at the inner side of the fixing device, the elastic part 3 and the main sliding block 23 sleeved on the guide rod, the baffle plate 12 connected with the elastic part 3 and the induction matching part 22 are positioned at the inner side of the fixing device, and only the hanging part 21 extends out of the outer side of the fixing device for users to use, so that the appearance of the whole structure is beautified, the interference of irrelevant signals on the inductor switch 13 is reduced, the cleanness degree of the internal structure is ensured, and the service life of the microphone induction hanging rack is prolonged. The direction of arrow a in fig. 1 is the outside of the fixture, an external structure visible to the user; the direction of arrow B is the inside of the fixture, which is an internal structure not visible to the user.
When the microphone is suspended, the fixing device is subjected to a rotating moment caused by the gravity of the microphone in addition to the gravity of the microphone, and the rotating moment causes a certain torque at the joint of the fixing device and the moving device, so that the smoothness of the upward or downward movement of the moving device is influenced. Therefore, the moving device of the present invention may further include a matching slider 24 having a through hole formed therein, so that the suspension member 21 is balanced and does not shake downward when moving upward and downward. The matching slider 24 is fixed on the hanger 21 and moves synchronously with the main slider 23, and the through hole is sleeved on the lower parts of the two guide rods 11 to disperse the stress and torque of the main slider 23. Balls which are in rolling friction with the guide rod 11 can be arranged on the inner walls of the through hole and the stepped hole, so that sliding friction of movement between the main sliding block 23, the matching sliding block 24 and the guide rod 11 is converted into rolling friction, movement resistance is reduced, the problem of movement resistance caused by torque is avoided, and the main sliding block 23 and the matching sliding block 24 can slide more smoothly along the guide rod 11. The engaging slider 24 may be fixed to a fixing pin 26 at the lower portion of the suspension member 21 by a connecting member 25, and the embodiment shown in fig. 4 illustrates the connecting structure of the engaging slider 24 by taking only one connecting member 25 as an example, but the engaging slider 24 may be fixed to a plurality of fixing pins 26 by a plurality of connecting members 25, and the number of the connecting members 25 and the fixing pins 26 is not limited herein.
Generally, the microphone head is heavier than the microphone tail, and in order to ensure the stability of the microphone suspension, the suspension member 21 of the present invention includes an upper holding groove 211 for holding the microphone head and a lower holding groove 212 for holding the microphone tail; the central lines of the upper bearing groove 211 and the lower bearing groove 212 are superposed, and wire groove openings communicated with the outside are formed in the same direction so as to avoid microphone wires of the wired microphone; as shown in fig. 3, the lower end of the hanger 21 is inclined upward, and the inclination angle α of the center line to the vertical horizontal direction is 5 ° to 30 °; the vertical distance between the upper supporting groove 211 and the baffle plate 12 is less than half of the vertical distance between the upper supporting groove 211 and the lower supporting groove 212, so that the baffle plate 12 fixes the elastic member 3 on the upper part of the fixed moving device, the upper supporting groove 211 is used as a main bearing part, and the torque generated by the microphone head at the joint of the fixed device and the moving device is reduced; when the microphone is obliquely placed, the placing angle is more humanized, and the center of gravity is more stable after the microphone is placed; the downward movement of the elastic element 3 can be better controlled under the action of the dead weight.
In a preferred embodiment, the inclination angle α of the central line with respect to the vertical horizontal direction is 15 °, and the vertical distance between the upper holder groove 211 and the baffle 12 is one third of the vertical distance between the upper holder groove 211 and the lower holder groove 212. The inclination angle and the vertical distance both influence the torque of the joint of the torque fixing device and the moving device, and research and development personnel do a lot of experiments to find that the torque generated by the embodiment has better acting force on the elastic part, so that not only can appropriate force be generated, but also the service life of the elastic part can be effectively prolonged.
Public health problems are a particular concern when the present invention is applied to public equipment. In view of this, the heating coils are arranged in the circumferential direction of the upper supporting bracket 211 and the upper supporting groove 212, and corrugated plastic parts are coated outside the heating coils; when the inductor switch 13 is turned off, the microphone is placed in the hanging part 21, the power supply can be controlled to be connected with the heating coil, and the heating coil starts to heat for disinfection and sterilization; when the inductor switch 13 is closed, the induction matching piece 22 is reset, the microphone is picked up, the power supply can be controlled to disconnect the heating coil, and the heating coil stops heating; the residual heat of the microphone can also evaporate the water vapor of the microphone head, so that the microphone head is kept dry. The microphone response stores pylon embodiment that has heating coil in this technical scheme has solved the problem of disinfecting and dry microphone head, and corrugated plastic part can start cushioning effect, and striking and vibrations when making the microphone place are littleer, have reduced the harmful effects to the microphone. If the microphone is heated before the electric signal is disconnected, radiation generated by heating of the heating coil can affect a precision device in the microphone connected with the electric signal, and the long-time radiation can reduce the service life; therefore, the scheme is heated after the electric signal is cut off, and the influence on a precise device is avoided.
On the basis of the preferred embodiment of the present invention, the problem of the resistance of the gravity moment of the microphone to the sliding of the main slider 23 can be further optimized. Besides the balls arranged on the contact surface of the main slider 23 and the guide rod 11, the stepped hole of the main slider 23 can be a flat hole, and the long axis direction of the flat hole is consistent with the axial direction of the connecting piece 25. When the microphone generates a rotation moment on the main slider 23 under the action of gravity, the main slider 23 has a moment of deflecting towards the microphone; in the embodiment, the contact hole between the main sliding block 23 and the guide rod 11 is designed as a flat hole, so that the influence of the deflection moment can be reduced; even if the main slider 23 is slightly deflected, since it has a large fitting clearance in the deflecting direction, no hindrance of sliding is caused.
The sensor switch 13 can be formed by connecting various sensors and sensor circuits. For example, the different gravitational forces generated by the microphone hanging and not hanging can be sensed by means of a force sensitive sensor: when the induction matching part 22 moves downwards or upwards along with the mobile device, parameters such as resistance or capacitance of a force-sensitive sensor in the sensor switch 13 are changed, the parameter change causes the signal change of the sensor switch 13, and whether the microphone is hung on the hanging part 21 is judged according to the signal change; the position of the microphone can also be sensed by a magnetic sensor: when the induction fitting 22 moves downward or upward with the mobile device, the magnetic field of the magnetic sensor in the sensor switch 13 is changed, and whether the microphone is suspended on the suspension member 21 is determined by the change of the magnetic field or the change of the current and voltage caused by the change of the magnetic field. The induction engagement member 22 is sufficient to cause the sensor switch 13 to generate a corresponding sensor signal, and the fixed position thereof can be determined according to the type of the specific sensor switch 13. For example, the induction mating member 22 may be disposed at a position opposite to the sensor switch 13, and perform wireless induction through a non-contact electric field or electromagnetic signal, or may contact the sensor switch 13, so that the force sensor generates a deformation induction signal through a contact force; the specific positions of the sensors can be referred to in the installation mode of each sensor in the prior art, and are not described in detail herein.
The invention preferably uses photosensitive sensors, such as: the sensor switch 13 is an infrared ray correlation sensing piece comprising a transmitter and a receiver, and the sensing matching piece 22 is a sensing shifting piece capable of shielding infrared rays; when the main sliding block 23 is reset upwards, the induction poking sheet is inserted between the emitter and the receiver to block the receiver from receiving the infrared signal of the emitter; when the main sliding block 23 is forced to compress the compression spring downwards, the induction poking sheet moves out between the emitter and the receiver, and the receiver receives an infrared signal of the emitter; the position of the induction dial plate can be judged by judging whether the receiver can receive the infrared signal of the transmitter, and then whether the hanging piece 21 is pressed down or reset is judged, and whether the microphone is positioned in the hanging piece 21 is known.
In a preferred embodiment of the present invention, the elastic member 3 is a compression spring, and in order to prolong the service life of the compression spring, the present invention may further include an extension spring, wherein the upper end of the extension spring is fixed on the baffle 12, and the lower end of the extension spring is fixed on the lower portion of the moving device; when the mobile device moves downwards under the self-gravity of the microphone, the extension spring is driven to extend, and the extension spring and the compression spring store elastic potential energy together. When the dead weight of the microphone is lost, the extension spring and the compression spring release elastic potential energy together, and the extension spring is shortened to reset the mobile device. After a single spring is used alone for a long time, a matching error between the sensor switch 13 and the induction matching piece 22 may occur due to the natural falling of the spring and the like, so that the judgment structure of whether the microphone is positioned in the hanging piece 21 is influenced; embodiments of the present invention use tension members in conjunction with compression members to reduce such errors.
As a preferred embodiment, the size of the extension spring is the same as that of the compression spring, the number of the compression springs is two, the number of the extension spring is one, the lower compression spring bears the weight, the upper extension spring plays a role in adjusting force, and the structure is favorable for matching the sensor switch with the induction matching piece.

The foregoing is only a partial embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
