Background

The invention of this patent results from the in-person experience of the inventor over the industrial field and work. The inventor has experienced in-person experience of managing production and debugging and overhauling of production line equipment in a factory, and particularly when the inventor commands subordinate staff to overhaul and debug production line equipment in the workshop, the inventor finds that the wireless microphone is connected with the sound amplifying equipment, so that compared with an interphone, the wireless microphone can better transmit instructions to related overhauling and debugging personnel scattered at various places of the workshop in the large field at the same time, and even transmits the instructions to related personnel without the interphone at the first time. As long as a loud speaker or a sound box is installed near each important device on the site of a factory workshop, the instruction of the inventor can be timely transmitted to all operators on the site. If the interphone is used, the situation that the communication signal of the interphone is not smooth or the storage battery in the interphone is not electrified can be often met, so that the interphone is directly and conveniently used by a large loudspeaker or a sound box, and the equipment regulation and control instruction can be simultaneously transmitted to all staff in a workshop site. Along with the general promotion of the industrial informatization degree of China, more and more factories are equipped with industrial control software and hardware called as a distributed control system, the control software of the distributed control system is mainly installed in a workstation computer and is also more and more installed in smart phones of managers at all levels of the factory, and the industrial distributed control system APP software (APP is in an abbreviation form of the first three letters of English Application) installed in the flat smart phones can display various parameters of equipment in real time and even call videos of related cameras, so that the industrial distributed control system APP software is more and more in the industrial production field and is also more and more the standard configuration of managers at all levels. A writer likes to use the distributed control system APP software installed in the smart phone and the wireless microphone for sound amplification at the same time when examining and debugging a large production line in a factory at first, meanwhile, tools such as a torque wrench, a screwdriver, an infrared temperature measuring gun and the like are used, so that various production data displayed by the distributed control system APP in the smart phone need to be paid attention to at any time, and meanwhile, one hand is used for holding a wireless microphone to direct other staff in a workshop field to carry out related debugging or maintenance operations, and at times, a hand is required to be vacated, either the microphone or the mobile phone is put down, tools such as a torque wrench, a screwdriver and the like are operated to debug or overhaul production line equipment, and due to the concentration of attention, therefore, the user often forgets to lose his own smart phone or wireless microphone on the workshop site, and even attaches the smart phone or wireless microphone to his own belt by using two ropes for a while to prevent the smart phone or wireless microphone from being lost. The inventor has now devised an idea of allowing a user to hold a wireless microphone while holding and operating a smart phone with the same hand, so that one of the two hands of the user can hold two non-detachable devices, namely the smart phone and the microphone, while the other hand can leave free a man-machine interface from operating tools such as a torque wrench, a screwdriver, an ammeter, etc., or from operating buttons and a touch screen on a dashboard of a machine tool. In the civil field, the inventor notices that singing with a wireless microphone connected with a sound system is gradually becoming a favorite of consumers and private car owners in recent years, in particular to a wireless microphone which is wirelessly connected with a smart phone of a user in a Bluetooth transmission mode to receive accompanying music and mix the voice received by the microphone and then transmits the accompanying music and the voice to multimedia sound systems such as a vehicle-mounted radio, a vehicle-mounted sound or an indoor sound system for playing through wireless connection modes such as frequency modulation broadcasting and the like. The wireless microphones on the market are generally expensive, one of the main reasons is that many wireless microphones are built with a built-in memory chip for storing song accompaniment and provide an external input interface such as a USB (USB is an abbreviation of Universal Series Bus) interface, and a high-performance microprocessor with a very low price is built for processing functions such as retrieving and playing selected song accompaniment from the built-in memory chip, adjusting song accompaniment and high and low voice of human voice received by the wireless microphone, and the increase of functions also requires a button, a knob or a slide button to be added on the surface of the wireless microphone, and the slightly higher-level wireless microphone also provides a small man-machine interaction interface such as a display screen or a touch screen, including a built-in memory chip, an external input interface, a high-performance microprocessor, The cost and price of a wireless microphone are undoubtedly increased by devices including buttons, knobs, slide buttons and human-computer interaction interfaces. However, in fact, these functions and the corresponding required devices can be completely realized and provided by the existing smart phone, it is well known that the update speed of the hardware of the existing smart phone and the performance improvement speed already exceed the hardware update speed of a desktop computer, and a man-machine operation interface which is pleasant and convenient and fast to use can be provided by matching a large-area touch screen of the modern smart phone with mobile phone APP software which is well-organized, so that an ultra-large-capacity storage space is built in the modern smart phone, hundreds of accompaniment of songs can be put down enough, the accompaniment of the songs can be directly downloaded from the network by using the smart phone, an external input/output interface is not needed, and the music playing software APP application program in the smart phone can easily realize the adjustment of output sound effects such as high and low tones. Therefore, as long as the modern smart phone can be fully utilized, unnecessary expansion of the wireless microphone in function can be completely avoided, so that the production cost and the selling price are reduced, natural and social resources are saved, in fact, the wireless microphone needs to be well done, namely wireless Bluetooth communication with the smart phone and wireless FM broadcast communication with a vehicle-mounted radio or an indoor sound system, and other things can be delivered to the modern smart phone for execution and perfection. In order to perfectly realize the purpose of using the wireless microphone and simultaneously fully utilize the smart phone, and solve the problem of how to simultaneously operate the wireless microphone and the smart phone by a user, the conventional straight bar-shaped wireless microphone comprises an acoustoelectric conversion unit wrapped by a dustproof mesh enclosure at the uppermost end and a handle held by the user below the acoustoelectric conversion unit, when the user wants to simultaneously use the smart phone and the conventional straight bar-shaped microphone, the user needs to hold the handle of the microphone, and hold the smart phone, both hands of the user are occupied, and other things cannot be done, for example, when the user wants to hold a screwdriver, a torque wrench and the like in the industrial field to overhaul equipment or operate various switch buttons on a control panel of the equipment, or when the user wants to drink a drink, or sing a friend together, one of the left hand and the right hand has to be removed, either the smart phone or the wireless microphone is dropped, which is difficult and inconvenient. If a microphone is provided, a user can operate the smart phone and hold the microphone with one hand at the same time, and meanwhile, the use mode and the use habit that the sound-electricity conversion unit which is the same as the traditional wireless microphone is positioned above the palm tiger mouth of the hand holding the microphone by the user are also continued, so that the use requirements of professional users in the industrial field can be met, the requirements in the civil life and entertainment field can be met, more pleasure and convenience can be brought to consumers, and the production cost and the selling price of the microphone can be greatly reduced.

Compared with the traditional straight bar-shaped wireless microphone, the handle of the traditional integral straight bar-shaped wireless microphone is the acoustoelectric conversion unit pointing to the upper top end of the handle of the traditional straight bar-shaped wireless microphone, and the acoustoelectric conversion unit is still positioned above the user holding object due to the introduction of the contact plate of the intelligent mobile phone, which is a technical characteristic of the invention for keeping and continuing the habit of the consumer using the traditional wireless microphone. When the invention is implemented specifically, the number of the connecting rods can be two, so that the hollow part between the two connecting rods can well accommodate the protruding part at the joint of the fingers and the palm of the back of the palm of the user, namely the connecting rods and the user are prevented from curling to hold the back of the palm of a smart phone to generate interference, and more comfortable use experience is brought to the user; in addition, the number of more than one connecting rod can more effectively simulate the outer surface of the integral straight-bar-shaped handle of the common wireless microphone, and compared with the single connecting rod, two or more than two connecting rods can enable a user to obtain more comfortable hand feeling experience when the user uses the invention in a traditional mode of using the common wireless microphone by holding the handle; when a user holds the handle of the invention consisting of the base, the smartphone attachment plate and all the connecting rods in a manner of using a common wireless microphone, since the sound-electricity conversion unit is fastened on the base and the handle, the microphone is similar to the common straight bar wireless microphone in shape and function, thus, the present invention can completely enable the user to use the conventional wireless microphone and achieve the same use effect as the common integral straight-plate wireless microphone, as mentioned above, the present invention can also enable the user to hold the smart phone and hold the microphone with the same hand in an innovative microphone using manner, which can be both fish and bear's paw.

As shown in fig. 2 and described with reference to the drawings of fig. 2, when a next mobile phone accessory named "finger ring buckle" is becoming a standard of a smart phone, more and more young people purchase their own smart phones and simultaneously select a finger ring buckle to be adhered to the back of the smart phone. In order to fully utilize the mobile phone accessory which is almost formed into a smart phone standard, the smart phone leaning plate is provided with an overlapped through hole array along the length direction, every two through holes forming the overlapped through hole array are partially overlapped, the through holes can be inserted by a ring and a cylindrical ring hinge frame of a ring buckle accessory on the back surface of a front touch screen of the smart phone, the inner diameter of the overlapped part of the through holes is smaller than the outer diameter of the ring hinge frame, the ring hinge frame can be limited in one through hole and cannot enter the other through hole through the overlapped part between the through holes, and the vertical height position of the ring buckle and the whole smart phone relative to the invention and the palm of a user is fixed after the ring and the ring hinge frame are inserted into one through hole, so that the negative holding of the smart phone by the user can be reduced Carrying out the steps. The hollow interiors of the base and the base are provided with cavities, the two cavities provide necessary space for placing parts of the electronic control system such as a printed circuit board, a storage battery and the like of the electronic control system, and the accommodating function of a hollow handle of a common wireless microphone is actually continued. The industrial and civil dual-purpose microphone also comprises an elastic spiral cable, the upper end and the lower end of the spiral cable positioned between the base and the base respectively extend into the respective cavities of the base and the base, so that electronic control system components in the two cavities of the base and the base can form an electronic control system with complete functions through the spiral cable; in the present invention, the spiral cable also occupies most of the space between the smartphone attachment plate and all the connecting rods, that is, more than half of the space between the smartphone attachment plate and all the connecting rods, and the user can insert four fingers, i.e., the index finger, the middle finger, the ring finger, and the little finger, or the palm of one palm between the base and between all the connecting rods and the spiral cable, then hold one smartphone with the four fingers and the palm around the smartphone attachment plate and the spiral cable, and operate the smartphone with the thumb of the same hand, and the spiral cable originally located between the smartphone attachment plate and all the connecting rods will be elastically deformed by the four fingers or the palm of the user inserted between the smartphone attachment plate and all the connecting rods while being put through And (3) applying extrusion through a ring of the smart phone pasting plate and forcing the ring to perform bending rotation around a ring hinge frame so as to connect the smart phone to the smart phone pasting plate and even the industrial and civil microphones, wherein the same hand of a user holds the smart phone pasting plate and the whole industrial and civil microphones on the same palm of the same hand. The spiral cable similar to the spiral signal line between the microphone and the base of the fixed telephone can play five roles, and can be used as a traditional cable for transmitting electric signals and electric energy; secondly, the smart phone and the whole industrial and civil dual-purpose microphone can be more firmly connected into a whole through the finger buckle after being extruded by the fingers or the palm of a user to generate elastic deformation by utilizing the elasticity of the smart phone, and the user only needs to hold the smart phone to actually hold the smart phone, so that the functions of holding and controlling one smart phone and holding the microphone by the same hand are realized; secondly, even if the user's smartphone is not equipped with a finger ring buckle accessory, the spiral cable is clamped between the smartphone attachment plate and the palm of the user's finger and receives elastic reaction force generated after extrusion, so that the user's finger or palm is actually fastened among the spiral cable, all the connecting rods and even the entire industrial and civil dual-purpose microphone, namely fastened and held on the hand of the user holding and operating the smartphone; third, even if the user's smartphone is not equipped with a finger ring accessory, when the user's curled fingers and palm are wrapped around the smartphone attachment plate to hold the smartphone, the spiral cable that is filled in the user's palm and is elastically deformed by the user's fingers and palm and the smartphone attachment plate will give the user's palm a feeling of fullness similar to holding a normal straight-bar microphone handle, trying to create a hollow void in the user's curled palm due to the thin, thin sheet-like shape of the smartphone attachment plate when the user holds a smartphone around the smartphone attachment plate without introducing the spiral cable. Of course, for a smart phone equipped with a ring buckle accessory, the spiral cable still brings a full and substantial grip feeling to the user; finally, the spiral cable, which occupies most of the space between the smartphone attachment plate and all of the tie bars, also gives the user a full and substantial grip when the user holds the handle of the present invention, which is comprised of the base, the smartphone attachment plate, and all of the tie bars, according to conventional wireless microphone usage, due to the everywhere prominent nature of its spiral periphery, just as the full and substantial grip obtained when holding the generally straight stick handle 11 of a conventional wireless microphone.

In the present invention, the spiral cable is required to have an outer diameter as large as possible to occupy the space between the smartphone attachment plate and all the connecting rods, and is required to ensure that the spiral cable is located as long as possible in the space between the smartphone attachment plate and all the connecting rods. Therefore, the elastic cable binding band can effectively enable the spiral cable to always keep the trend of being located between the smart phone leaning plate and all the connecting rods as far as possible, and therefore the five functions of the spiral cable are smoothly achieved.

As a technical solution further optimized on the above-mentioned optimized technical solution, in order to facilitate a user to perform integral compression and extrusion on the spiral cable when inserting the ring and the ring hinge frame into the overlapping through hole array, an elastic attachment band is closely attached to the back inner side surface of the smartphone attachment plate facing the connection rod and the spiral cable, all elastic cable straps for binding the spiral cable are fastened to one side surface of the elastic attachment band facing the spiral cable, and the elasticity of the elastic attachment band drives the elastic attachment band to always keep a tendency not to deviate from the inner side surface of the smartphone attachment plate. Therefore, when a user inserts the ring and the ring hinge frame of the finger ring buckle accessory on the back of the smart phone into the overlapped through hole array, the user can conveniently grasp all the connecting rods and the spiral cable with one hand, and then pick up the elastic sticking belt with the fingertips and extrude the spiral cable through the elastic sticking belt, so that the elastic sticking belt can be smoothly forced to be flat, and the ring can smoothly enter the inner side of the back of the smart phone sticking plate. In addition, the elastic pasting belt can press, bend and rotate the ring together with the spiral cable by means of the elasticity of the elastic pasting belt, so that the elastic pasting belt always keeps a position of being clung to the inner side surface of the intelligent mobile phone pasting plate, and therefore reliable connection between the intelligent mobile phone and the intelligent mobile phone pasting plate is guaranteed.

In the present invention, as another optimized implementation manner of the above-mentioned overlapped through hole array, a manner of generating the overlapped through hole array on the smartphone attachment plate is not to directly punch a hole on the smartphone attachment plate, the overlapped through hole array is to be located on a back surface of a straight groove along a length direction of the smartphone attachment plate, and the overlapped through hole array is composed of two spring steel wires welded to the straight groove toward a back surface of the spiral cable. That is, the smartphone attachment plate is provided with a straight groove along the length direction thereof, and the two spring steel wires which are welded to the straight groove and face the back of the spiral cable form the overlapped through hole array. The two spring steel wires are provided with a bending structure forming the overlapped through hole array; the width of the straight groove is larger than the outer diameter of the ring hinge frame, the ring hinge frame which extends into the overlapped through hole array can be manually driven to overcome the elasticity of the spring steel wire to prop open the overlapped parts of the through holes in pairs so as to enter the adjacent through hole from one through hole. This facilitates the user in dynamically adjusting the vertical height position of the smartphone relative to the entire industrial and residential wireless microphone when using the present invention. And the elastic overlapped through hole array has good adaptability to the ring buckles of the smart phones with various dimensions as long as the width of the straight groove is controlled to enable the straight groove to accommodate the ring hinge frame.

In summary, the industrial and civil dual-purpose microphone provided by the invention not only enables a user to hold and operate a smart phone with one hand and hold the industrial and civil dual-purpose microphone, but also keeps and continues the use habit of using the traditional straight bar-shaped wireless microphone and the use feeling of the sound-electricity conversion unit above the palm tiger's mouth of the user, provides great convenience for both the industrial field and the civil daily entertainment field, greatly reduces the production and manufacturing cost and the selling price of the industrial and civil dual-purpose microphone provided by the invention due to the simplification of functions, and ensures that the price, the light weight and the mentioned various advantages of the parent and civil dual-purpose microphone are certainly popular with the majority of users.

The ring buckle and its method of use are not described in detail herein since they are almost well known and popular techniques. Of course, as mentioned above, even if the user's smartphone is not equipped with the ring buckle accessory, the functions of holding and controlling the smartphone and holding the product of the present invention can be realized by the same hand.

FIG. 3 is a schematic diagram showing three viewing angles for a first embodiment of an industrial and residential dual-purpose microphone used with a smart phone; in the figure, a horizontal straight line double-direction arrow is separated and indicates two using states whether the first embodiment is connected with the smart phone or not, and also indicates that the smart phone of a user can be combined with the embodiment or can be completely restored from the combined state to the non-combined state, a plus sign in the figure indicates that the smart phone and the invention can be combined for use, and certainly can be completely separated, so that the smart phone 7 can be completely separated from the product of the invention as long as the user draws fingers and palms out of the smart phone attaching plate 4 and all the connecting rods 5, rotates the ring 7021 and draws out the smart phone attaching plate 4 together with the ring hinge rack 7022 from the overlapped through hole array 302, and the scalability and elasticity of the spiral cable 6 similar to a spiral signal line between a fixed telephone base and a microphone can ensure the smart phone and the smart phone to be completely separated from the product of the invention, and the scalability and the elasticity of the spiral cable 6 similar to a fixed telephone base and a microphone can ensure the smart phone and a separation process enabling the mobile phone to abut against the plate 4 is fully feasible. The right side of the horizontal straight-line bidirectional arrow shows a state where the smartphone 7 equipped with the attachment of the finger ring buckle 702 at three observation angles is connected with the present embodiment and can be used by a single hand of a user at the same time, and two horizontal arc bidirectional arrows in the present figure are separated to form three different observation angles of the use state. To highlight the key features of the present embodiment, the figures, like fig. 1, omit the fingers and palm of the user's hand extending between the upper and lower handles, but the reader is fully imaginable of a specific use case with reference to the present specification and all the drawings attached thereto. Referring to fig. 1 and this figure, in the present embodiment, the smart phone backup plate 4 has the technical features of the overlapping through hole array 402 as described above, the inner diameter of the overlapped portion of every two through holes is smaller than the outer diameter of the ring buckle hinge frame 7022, and the inner diameter of each through hole is larger than the outer diameter of the ring buckle hinge frame 7022, the ring 7021 of the ring buckle 702 extending into the back of the smart phone backup plate 4 and bending to the inner side of the back of the smart phone backup plate 4 connects the smart phone 7 and the smart phone backup plate 4 together, and the cylindrical ring buckle hinge frame 7022 in fig. 2 extends into one through hole of the overlapping through hole array 402 on the smart phone backup plate 4 as shown in this figure and fig. 1 and cannot slide up and down, so that the vertical up and down position of the smart phone 7 is fixed, and when the helical cable 6 is crushed, the elastic deformation naturally bends and rotates the bent and rotated through hole array 402 The pressing of the ring 7021 ensures the connection between the smartphone 7 and the smartphone backup plate 4. In this way, the smartphone 7 can be held relatively firmly without falling off easily due to the clamping of a smartphone attachment plate 3. Of course, even for a smartphone without a finger ring buckle, the present invention does not prevent the user from firmly holding the smartphone, and after all, the smartphone attachment plate 4 is only a long and narrow metal sheet, and is sandwiched between the smartphone and the user's fingers or palm, which not only does not cause much interference, but also helps to position the smartphone 7 in a proper direction and position, because the back of the smartphone 7 naturally adheres to the smartphone attachment plate 4 when being held. In fact, most users experience and experience too much to hold and manipulate the smartphone at ordinary times, so there is no undue concern that the smartphone 7 will fall from the user's hand when not connected to the smartphone rest plate 4 unless the user so desires. In summary, the smart phone 7 connected to the smart phone backup plate 4 shown in the figure can be held and controlled steadily, so that the user can completely adjust the vertical height of the smart phone to the position where the sound-to-electricity conversion unit 1 is just above the top of the smart phone 7 as shown in the figure, i.e. the sound-to-electricity conversion unit 1 is located above the handle 11 held by the user when using a common wireless microphone, but the user holds the smart phone 7 not the handle 11 but is used ordinarily when using the present invention. Certainly, the smartphone 7 cannot be held and operated with the same hand when the handle 11 of the ordinary wireless microphone is held, but the present invention can also retain and continue above the tiger's mouth of the palm of the user, that is, above the holding object held by the hand, which is the use feeling and the use habit of the sound-electricity conversion unit 1 that needs to be close to the mouth.

FIG. 4 shows a schematic view of the first embodiment, disassembled step by step; in the figure, two bidirectional straight arrows are used for separating three state schematic diagrams which are disassembled step by step from left to right, the leftmost side is the state when the smart phone clinging plate 4 is disassembled first, the middle is the state when all the connecting rods 5 are disassembled, and the right side is the state when the base 2 and the base 3 are also disassembled in two parts, so that the right side figure omits parts of electronic control systems such as a printed circuit board, a storage battery, an antenna and the like which are arranged in two cavities 10 of the base 3 and the base 2 for highlighting key technical characteristics. It can also be seen from this figure that the smartphone abutment plate 4 and all connecting rods 5 of the first embodiment are actually two simple sheet metal parts, and the array of overlapping through holes 402 thereon are punched out continuously by the punch of a numerical control press or cut out at one time by a laser cutter. It can be seen from the figure that, both sides of the smartphone attachment plate 4 of the first embodiment have a bending structure in the whole length direction, and the bending of both sides can enhance the strength of the smartphone attachment plate 4 in a thin sheet shape, and can also simulate the cylindrical or long truncated cone-shaped outer surface of a straight bar-shaped handle of a common wireless microphone as much as possible as described above, and can also help to fix the spiral cable 6 so that it is always located inside the back of the smartphone attachment plate to successfully implement the five functions of the spiral cable. In order to make the reader clearly see the assembly and disassembly of the parts, the figure also indicates the matching of some parts and related fasteners and the installation positions thereof by using double-dot chain lines.

Fig. 5 shows a second embodiment of the invention from two viewing angles. Comparing this figure with fig. 1, fig. 3 and fig. 4, it can be seen that the second embodiment is only to add the cable tie 404 and the elastic attachment band 403 on the inner side of the back of the smartphone attachment plate 4 on the basis of the first embodiment, and it can be seen from this figure that the manner of adding the cable tie 404 and the elastic attachment band 403 is also very simple, and it is only necessary to fasten the upper and lower ends of the two on the base 2 and the base 3 with screws together with the upper and lower ends of the smartphone attachment plate 4, respectively. Note that the second embodiment may also be completely free of the elastic abutment band 403 and may leave only one cable tie 404, i.e., the second embodiment has two embodiments, namely only one cable tie 404 and one elastic abutment band 403, respectively. The advantage of adding the elastic bands 403 is that it is convenient for the user to integrally squeeze the spiral cable 6 and fix the ring buckle 7021 together with the spiral cable as described above, and after adding the elastic bands 403 and combining the elastic bands 404, the spiral cable 6 becomes a cylindrical elastic body with a continuous outer surface on the side facing the smartphone attachment plate 4, when a user plugs the ring buckle 7021 and the ring hinge rack 7022 into the overlapped through hole array 402, the cylindrical elastic body can be directly pushed open by the ring buckle 7021 and the ring hinge rack 7022 without pinching the spiral cable 6 flat by one hand, and when the ring 7021 and the ring buckle 7022 are pulled out of the overlapped through hole array 402, the cylindrical elastic body is convenient for being pushed open by the user or directly pulled and hardened out of the ring 7021 of the overlapped through hole array 402 to be pushed open.

Fig. 6 illustrates a third exemplary embodiment of the present invention from two viewing perspectives. In this figure a double-headed curved arrow separates the schematic view of the third embodiment from two viewing perspectives, the figure to the right of the double-headed curved arrow omitting the spiral cable 6 and the cable tie 404 and the elastic abutment band 403 in order to highlight the technical feature that the two spring steel wires 8 form the overlapping through-hole array 402, and in this figure the right side of a right-hand arrow indicates an enlarged close-up of the overlapping through-hole array 402 in the schematic view to the left of the arrow. Note that the third embodiment may also be completely free of the cable tie 404 and the elastic abutment band 403 shown in the figures. In fact, the third embodiment differs from the first and second embodiments only in the implementation of the overlapping via array 402. Unlike the first and second embodiments, in the third embodiment, the overlapping via array 302 is not directly cut out of the smartphone attachment plate 4, but a straight groove 401 is first machined, as mentioned above, the width of the straight slot 401 is sufficient to accommodate the finger ring hinge rack 7022 of the smart phone finger ring buckle 702, which extends into the straight slot 401 and slides up and down in the straight slot 401, the two twisted spring steel wires 8 actually forming the overlapped through hole array 402 are actually welded to the back of the smart phone attachment plate 4 facing the spiral cable 6 and the connection rod 5, the two spring steel wires 8 are deliberately processed into a curved shape and then combined together to form an overlapping through hole array 402, and the gray filled parts at the upper and lower ends of the two spring steel wires 8 in the enlarged view at the rightmost side in the figure indicate the welding seams where the spring steel wires 8 are welded to the inner side of the smartphone attachment plate 4. As mentioned above, the width of the overlapped part of each two of the through holes of the overlapped through hole array 402 is smaller than the outer diameter of the ring hinge frame 7022, so that the third embodiment can completely realize all the functions of the two embodiments, but the third embodiment has the advantage that the overlapped through hole array 402 is elastic, that is, a user can hold the smartphone 7 with force to open two spring steel wires 8 to freely shuttle in the straight slot 401, and after reaching a new height position, the fixed overlapped through hole arrays as in the first and second embodiments can be restored by the elastic force of the two spring steel wires 8, thereby completing the auxiliary fixing of the vertical height of the smartphone 7. In addition, due to the elasticity of the spring wire 8, the present embodiment can be even well adapted to finger ring hinge frames of various sizes without the need to prepare so-called "set meal" sizes of various through hole sizes in advance, because a slightly smaller finger ring hinge frame can be well wrapped by two spring wires 8. Note that fig. 3 may actually demonstrate the effect of the second and third embodiments on the connection of the smartphone 7 to the smartphone attachment plate 4 via the finger ring 702. Finally, referring to all the drawings in the specification except fig. 2, it can be seen that the sound-electricity converting unit 1 wrapped by the dust-proof mesh enclosure and the sound-electricity converting unit above the common integral straight bar-shaped wireless microphone handle 11 shown in fig. 1 are completely the same, and the innovation of the invention lies in the great innovation of the improvement of the traditional microphone handle and the holding mode thereof, especially the creative use of the spiral cable with elasticity.

Detailed Description

The following describes the technical solution of the present invention and three specific embodiments of the present invention in detail with reference to the drawings of the specification and the contents described in the above two sections of the description of the drawings.

Specifically, the present invention provides a first embodiment of an industrial and civil microphone, as shown in fig. 1, which, like the currently popular integral straight-bar wireless microphone, also includes an uppermost sound-to-electricity conversion unit 1 for receiving human voice and converting the human voice into an electrical signal, wherein the industrial and civil microphone can be connected to a multimedia sound system by wireless duplex, and the industrial and civil microphone can also be connected to a smart phone by wireless duplex. That is to say, the industrial and civil dual-purpose microphone provided by the invention can transmit the music accompaniment played by the smart phone and the human voice of the user received by the industrial and civil dual-purpose microphone to the vehicle-mounted radio system, the vehicle-mounted sound system or the indoor sound system in a frequency modulation broadcasting mode, like the common integral straight-bar wireless microphone. As shown in fig. 1 and referring to all the figures except fig. 2, the present invention is different from the conventional integral straight-bar wireless microphone in that the acoustic-electric conversion unit 1 is tightly mounted on a base 2, the dual-purpose microphone for industrial and civil use further comprises a thin-sheet-shaped smartphone attachment plate 4, the upper end of the smartphone attachment plate 4 is tightly fastened on the base 2, the lower end of the smartphone attachment plate 4 is tightly fastened to a base 3 of the dual-purpose microphone for industrial and civil use, the dual-purpose microphone for industrial and civil use further comprises at least one connecting rod 5 connecting the base 2 and the base 3, the upper end of each connecting rod 5 is tightly fastened to the base 2 and the lower end of each connecting rod 5 is tightly fastened to the base 3. As shown in fig. 1, the base 2 of the sound-electricity conversion unit 1 and the base 3 are fixedly connected into a whole through the smartphone attachment plate 4 and all the connecting rods 5, so that the whole straight bar-shaped handle 11 of a common wireless microphone can be simulated. In order to achieve the aforesaid function of holding the dual-purpose microphone for both industrial and civil use provided by the present invention with the same hand while a user holds and operates a flat bar-shaped smart phone, in the present invention, as shown in fig. 1 and referring to all the figures of the specification except fig. 2, the upper end of each of the connecting rods 5 is fastened to one side of the base 2 opposite to the smart phone backup plate 4, the lower end of each of the connecting rods 5 is fastened to one side of the base 3 opposite to the smart phone backup plate 4, that is, all the connecting rods 5 are located at the opposite side of the smart phone backup plate 4, so that a gap 9 is formed between all the connecting rods 5 and the smart phone backup plate 4, as shown in fig. 1 and 3, the gap 9 is used for a user's finger or palm to be inserted, therefore, the base 2 and the acoustoelectric conversion unit 1 thereon, and even the whole industrial and civil dual-purpose microphone can be erected on the finger or the tiger mouth of the user to realize the holding effect. In the present invention, as shown in fig. 1, the base 2, the base 3, the smartphone attachment plate 4 and all the connecting rods 5 that are fastened and connected to the base 2 and the base 3 form a straight rod-shaped whole that can serve as a handle of the industrial and civil dual-purpose microphone that can be held by a user, and in specific implementation, the base 2 and the base 3 only need to be shaped as a rotator and have axial directions thereof located in the same straight direction, and in the first embodiment, the base 2 and the base 3 are both in the shape of a long and narrow truncated cone rotator, so that the present invention retains and continues the customary usage and use experience of a common wireless microphone for the user, that is, the present invention is used by holding the handle assembled by the base 2, the base 3, the smartphone attachment plate 4 and all the connecting rods 5 with one hand. In fact, for the present invention, the handle 11 of the conventional microphone is divided into the base 2 with the upper part installed with the sound-electricity converting unit 1 and the base 3 with the smartphone leaning plate 4 and the connecting rod 5 to connect the base 2 and the base 3 into a hollow handle, and the handle with the hollow space 9 in the middle provides the possibility for the user to hold the smartphone and the microphone with one hand at the same time, that is, the fingers or palm of one hand of the user can penetrate the hollow space 9 in the middle part of the handle to mount the base 2 and even the whole microphone for both industrial and civil use on the fingers or palm to achieve the effect of holding the whole microphone, and the user does not need to hold and use the microphone with the whole hand holding the handle 11 like using the ordinary wireless microphone, therefore, the front ends of the fingers and the part below the tiger's mouth of the palm can obtain necessary freedom degree so as to hold and operate a smart phone. In particular, with reference to fig. 1 and 3, the four fingers or palms of the index, middle, ring and little fingers of one hand of the user can be inserted into the space 9 between the base 2 and the base 3, between the smartphone resting plate 4 and all the connecting rods 5, and be appropriately curled to hold a flat smartphone and also to manipulate the industrial distributed control system APP or multimedia K song APP software installed in the smartphone with the thumb of the same hand, while the whole of the industrial and civil microphone can be mounted on the user's index or palms, while the whole of the acoustic-electric conversion unit 1, which is located above the hollowed-out handle as shown in fig. 3 and 1, is located on the user's hand to achieve the aforementioned effect of being held on the user's hand, as long as the base 2 is connected to the base 3, and the base 1 is located above the hollowed-out handle The user holds the smartphone 7 and then winds up the forefinger and the upper part of the tiger's mouth of the palm, so that the use habit of the common straight-bar-shaped wireless microphone is continued and maintained. As shown in fig. 3, the smart phone backup plate 4 is introduced to position the smart phone 7 in a proper orientation when a user holds the smart phone and holds the dual-purpose microphone for industrial use and civil use provided by the present invention, in the present invention, the inner surface of the back of the thin-plate-shaped smart phone backup plate 4 is located at the opposite side of all the connecting rods 5 as described above, and the outer surface of the smart phone backup plate 4 faces the outer direction of the handle with a hollow-out middle part composed of the upper base 2, the lower base 3, the smart phone backup plate 4 and all the connecting rods 5. Referring to fig. 3, a user's fingers or palm extending into the gap 9 between the base 2 and the base 3 between the smartphone attachment plate 4 and all of the tie bars 5 will then, after a moderate curling, hold a smartphone 7 around the smartphone attachment plate 4, at which time the smartphone 7 will naturally lie closely against the smartphone attachment plate 4, and will naturally lie in a direction towards the acousto-electric conversion unit 1, as shown in fig. 3. Referring to fig. 1 and 3, compared to the conventional straight bar-shaped wireless microphone, the handle of the conventional integral straight bar-shaped wireless microphone is the acoustoelectric conversion unit pointing to the upper top end of the handle of the conventional wireless microphone but the user holds the own smartphone, and in the present invention, the acoustoelectric conversion unit 1 is still located above the user's grip due to the introduction of the smartphone attachment plate 4, which is a technical feature of the present invention that retains and continues the custom of the consumer to use the conventional wireless microphone. In the specific implementation of the present invention, as shown in fig. 1 and 3, the number of the connecting rods 5 can be two, so that the hollow portion between the two connecting rods 5 can well accommodate the protruding portion at the intersection of the fingers and the palm of the back of the palm of the user, that is, the connecting rods 5 can avoid interfering with the palm back of the smartphone held by the user in a curling manner, thereby providing a more comfortable use experience for the user, and of course, the number of the connecting rods 5 can be larger than two to simulate the outer surface shape of the integral straight-bar handle of the conventional wireless microphone as much as possible, referring to all the drawings of the specification except fig. 2, the number of more than one connecting rods 5 can simulate the outer surface of the integral straight-bar handle of the conventional wireless microphone more effectively, compared to the case of using a single connecting rod, two or more than two connecting rods can enable the user to use the conventional wireless microphone in a conventional manner of holding the handle When the invention is used, more comfortable hand feeling experience is obtained; when a user holds the handle of the present invention composed of the base 2, the base 3, the smartphone attachment plate 4 and all the connecting rods 5 in a manner of using a common wireless microphone, as shown in fig. 1, since the sound-electricity converting unit 1 is fastened to the base 2 and even directly above the handle in the present invention, an industrial and civil dual-purpose microphone provided by the present invention is almost the same as a common straight bar-shaped wireless microphone in shape and function, so that the present invention can completely allow the user to use the conventional wireless microphone in the habit and achieve the same using effect as a common integral straight bar-shaped wireless microphone, and can allow the user to hold and manipulate the smartphone and hold the microphone in the same hand in an innovative microphone using manner, can be obtained by fish and bear paw.

It should be noted that, in the present invention, as shown in fig. 1 and 3, the length direction of the smartphone attachment plate 4 is actually directed to the acousto-electric conversion unit 1 above the hollow-middle handle formed by the base 2, the base 3, all the connecting rods 5 and the smartphone attachment plate 4, when the user's fingers or palms pass through the smartphone attachment plate 4 and all the connecting rods to hold a smartphone 7 around the smartphone attachment plate 4, the smartphone 7 will be automatically attached to the smartphone attachment plate 4 in a state of being held by the human hand so that the top end above the smartphone can be located below the acousto-electric conversion unit 1, and the effect and the feeling of use of the present invention are the same as those of using a common integral straight-bar wireless microphone, and the difference is that only when the user holds the handle with a hand using a common wireless microphone, the handle is a straight-bar integral handle, when the invention is used, the user holds the smart phone, under two use conditions, the sound-electricity conversion unit 1 is positioned above the crook of the user, the user can still continue the habit and feeling of using the common wireless microphone, and the mode of holding the microphone can be an innovation of the traditional microphone use mode. Certainly, the user can freely adjust the relative distance between the smartphone 7 and the sound-electricity conversion unit 1 according to the preference of the user, and even adjust the smartphone 7 to the position where the sound-electricity conversion unit 1 is located behind the top of the smartphone, so that the user only needs to bring the sound-electricity conversion unit 1 and the smartphone 7 together close to the lips of the user to receive the voice when using the industrial and civil dual-purpose microphone. Certainly, for the invention, the main function of the invention is to enable a user to hold the smartphone with one hand and hold the industrial and civil dual-purpose microphone provided by the invention and to enable the sound-electricity conversion unit 1 to be positioned above the hand tiger mouth, so that the traditional habit that the user holds the smartphone and uses a common wireless microphone can be inherited and maintained, the user can conveniently and freely control the smartphone with the hand holding the microphone to select songs and adjust high and low sounds, and even the user does not delay or obstruct listening to the phone on the way of singing, and the other hand can be left free to do other things, for example, singing while drawing the gesture, singing while drawing friends or giving alcohol to friends and the like. For users in the industrial field, one hand can hold and control the industrial distributed control system software installed in the smart phone and hold a microphone for issuing commands to relevant employees on site, and the other hand can hold equipment such as a wrench and a screwdriver. Referring to fig. 1 and 3, in practice the present invention bisects the handle 11 of a conventional wireless microphone and allows the user's fingers and palm to be inserted into the handle and then curl around a thin sheet-shaped smartphone attachment plate 4 to hold a smartphone, because an elongated smartphone attachment plate 4 is much smaller in size than a full straight bar-shaped integral handle, so that the user can hold the smart phone 7 together with a flat plate without trouble and can operate the industrial distributed control system APP software or the karaoke for entertainment APP software installed in the smart phone with the thumb as freely as usual, for a common wireless microphone, if a user holds a straight rod-shaped integral handle in the palm, the palm inner space is completely occupied, and the user cannot hold and control a smart phone at the same time. In the present invention, referring to fig. 3 and fig. 1, at least two purposes and benefits of introducing the smart phone backup plate 4 are provided, the first is to provide a reference parking position for the smart phone of the user so that the acousto-electric conversion unit 1 can be located above the holding object as using the conventional wireless microphone when the user holds the smart phone, that is, to ensure that the acousto-electric conversion unit 1 is located above the tiger of the palm of the user when the user holds the smart phone, and to retain and continue the use feeling and use habit of the user brought by the acousto-electric conversion unit 1 being located above the tiger of the user when the handle 11 of the common wireless microphone is held. Since the smartphone attachment plate 4 sandwiched between the user's palm or finger and the smartphone is attached to the back surface of the smartphone 7 when the smartphone is held by the user's palm or finger, and the acousto-electric conversion unit 1 is indirectly fastened to the smartphone attachment plate 4 through the base 2 to be integrated, the smartphone 7 is located in the user's palm web and the acousto-electric conversion unit 1 is located above the user's palm web, that is, directly above the direction in which the smartphone extends; secondly, the smartphone attachment plate 4 and all the connecting rods 5 simulate the shape of a straight bar-shaped integral handle of a common microphone, so that a traditional microphone using mode of holding the handle is reserved for a user.

As shown in fig. 2 and described with reference to the drawings of fig. 2, when a next mobile phone accessory named "finger ring buckle" is becoming the standard of a smart phone, more and more young people purchase their own smart phones and simultaneously purchase a finger ring buckle 702 to be adhered to the back of the smart phone. In order to fully utilize the so-called "ring buckle" mobile phone accessory which is almost a smartphone standard, referring to all the figures except fig. 2, in the present invention, the smartphone attachment plate 4 has an overlapping through hole array 402 along the length direction thereof, all the through holes constituting the overlapping through hole array 402 are overlapped with each other in pairs, the through holes can be inserted by a ring 7021 of a ring buckle 702 accessory on the back side of the smartphone relative to the front touch screen thereof and a cylindrical ring hinge frame 7022, the inner diameter of the overlapped parts of the through holes is smaller than the outer diameter of the ring hinge frame 7022, so that the ring hinge frame 7022 can be limited within one through hole and cannot go into another through hole beyond the overlapped part between the through holes as shown in fig. 3, and after the ring 7021 and the ring hinge frame 7022 are inserted into one through hole as shown in fig. 3, the ring buckle 702 and even the whole part of the smartphone 7 can be mutually overlapped with each other through hole The vertical height position of the palm of the user and the present invention is fixed so that the burden of the user holding the smartphone 7 can be reduced. The base 2 and the base 3 of the first embodiment shown in fig. 4 have cavities 10 in their hollow interiors, and these two cavities 10 provide the necessary space for accommodating the components of the electronic control system, such as the printed circuit board and the battery of the electronic control system of the present invention, and actually continue the accommodating function of the hollow handle of the conventional wireless microphone. Referring to all the figures except fig. 2, the industrial and civil dual-purpose microphone further comprises an elastic spiral cable 6, and the upper and lower ends of the spiral cable 6 between the base 2 and the base 3 respectively extend into the respective cavities 10 of the base 2 and the base 3, so that the electronic control system components in the cavities 10 at two positions of the base 2 and the base 3 can form an electronic control system with complete functions through the spiral cable 6; in the present invention, referring to all figures of the specification except fig. 2, the spiral cable 6 occupies most of the space 9 between the smartphone attachment plate 4 and all the tie bars 5 and between the base 2 and the base 3, that is, occupies more than half of the space between the smartphone attachment plate and all the tie bars, and the user can insert four fingers or palms of the index finger, middle finger, ring finger and little finger of one palm into the space between the base 2 and the base 3 and between all the tie bars 5 and the spiral cable 6 and then hold one smartphone around the smartphone attachment plate 4 and the spiral cable 6 with the four fingers and palm, and manipulate the smartphone 7 with the thumb of the same hand, as shown in fig. 1 and 3, the spiral cable 7 originally located between the smartphone attachment plate 4 and all the tie bars 5 The cable 6 presses the four fingers or palms of the user, which are inserted between the smartphone attachment plate 4 and all the connecting rods 5, to be elastically deformed, presses the finger ring 7021, which passes through the smartphone attachment plate 4, and forces the finger ring 7021 to perform bending rotation around the finger ring hinge frame 7022, so that the smartphone 7 is connected to the smartphone attachment plate 4 and even to the industrial and civil microphones, and the same hand of the user holds the smartphone attachment plate 4 and the entire industrial and civil microphones in the same palm. The spiral cable 6, which is similar to a spiral signal line between a microphone and a base unit of a fixed telephone set, can play five roles, and can be used as a traditional cable for transmitting electric signals and electric energy; secondly, as shown in fig. 1 and 3, the smartphone and the entire industrial and civil microphone can be connected more firmly as a whole through the finger ring buckle 702 after being elastically deformed by the squeezing of the user's fingers or palm by using their own elasticity, and then the user only needs to hold the smartphone 7 and actually hold the invention, namely, the aforesaid functions of holding and operating a smartphone and holding a microphone with the same hand are realized, and in fact, the industrial and civil microphone is already held on the palm of the fingers even if the user does not hold the smartphone 7, because the user's fingers or palm are clamped by the spiral cable 6 and all the connecting rods 5 which are elastically deformed; secondly, referring to fig. 1, even if the user's smartphone is not equipped with a finger ring buckle fitting, the elastic reaction force generated after the spiral cable is clamped between the smartphone attachment plate 4 and the palm of the user's finger and squeezed actually fastens the user's finger or palm among the spiral cable 6 and all the connecting rods 5 and even the entire industrial and civil dual-purpose microphone, that is, the hand of the user holding and manipulating the smartphone is tightly held; third, even if the user's smartphone is not equipped with a finger ring accessory, when the user's curled fingers and palm are wrapped around the smartphone attachment plate 4 to hold the smartphone, as shown in fig. 1, the spiral cable 6, which is filled in the user's palm and is elastically deformed by the user's palm and the smartphone attachment plate 4, gives the user's palm a feeling of fullness similar to holding a normal straight-bar microphone handle, trying to create a hollow virtual void in the user's curled palm due to the thin sheet-shaped profile of the smartphone attachment plate 4 when the user holds a smartphone around the smartphone attachment plate 4 without introducing the spiral cable 6 of the present invention, and thus cannot simulate the feeling of fullness of the user in a grip of a normal microphone handle. Of course, as shown in fig. 3, for a smart phone equipped with a ring buckle assembly, the spiral cable 6 still brings a substantial sense of fullness to the user; finally, the spiral cable 6, which occupies most of the space of the gap 9 between the smartphone attachment plate 4 and all the tie bars 5, can also give the user a full and substantial grip due to the everywhere outward protruding nature of the spiral periphery as shown in fig. 1 when the user holds the handle of the present invention, which is composed of the base 2, the base 3, the smartphone attachment plate 4, and all the tie bars 5, according to the conventional wireless microphone usage method, just as the full and substantial grip obtained when holding the integral straight-bar handle 11 of a conventional wireless microphone.

As mentioned above, since the industrial and civil dual-purpose microphone provided by the present invention only needs to make a few limited functions such as receiving of voice of sound-electricity conversion unit, wireless bluetooth communication between smart phone, and wireless broadcast communication between vehicle-mounted radio or indoor sound system, the other functions can be delivered to modern smart phone for execution and improvement, although the space of the internal cavities 10 of the base 2 and the base 3 is smaller than the internal space of the handle of the whole straight bar shape of the ordinary wireless microphone as shown in fig. 4 and referred to in fig. 1, the area, volume and related parts of the circuit board of the electronic control system do not need to be much because only needs to pay attention to the matters which should be done as above, that is enough to be accommodated in the hollow cavities 10 inside the base 2 and the base 3, compared with other common wireless microphones with various functions, the invention simplifies the functions, greatly reduces the production and manufacturing cost, and can reach a price for the people. Referring to all the drawings of the specification except fig. 2, the invention skillfully utilizes the ring buckle of each smartphone label accessory to connect the smartphone and the smartphone attachment plate 4 and even the whole industrial and civil dual-purpose microphone together by processing the overlapped through hole array 402 on the smartphone attachment plate 4, so that the user can reliably grasp the smartphone 7 to ensure that the smartphone 7 cannot easily fall off under the condition that a thin-sheet smartphone attachment plate is inserted between the palm of the user and the smartphone. That is, after the ring 7021, which is located on the inner side of the back of the smart phone backup plate 4 after extending into a certain through hole of the overlapped through hole array 402, is squeezed by the spiral cable 6, which originally occupies most of the space of the gap 9, and rotates towards the smart phone backup plate 4, the ring can be continuously pressed by the spiral cable 6, so that the smart phone 7 and the smart phone backup plate 4 are connected together. In practice, referring to fig. 1 and 3, all the connecting rods 5 and the spiral cables 6 can be held by one hand and the spiral cables 6 are pressed to increase the distance between the spiral cables 6 and the smartphone attachment plate 4, then the ring 7021 is inserted between the longitudinally continuous channels of the overlapped through hole array, then the cylindrical ring hinge rack 7022 at the root of the ring 7021 is inserted into one of the through holes of the overlapped through hole array 402, and then the user releases the hand pressing the spiral cables 6 around the connecting rods 5, referring to fig. 3 and 1, at the moment, the spiral cables 6 restore the shape occupying most of the space of the gap 9 by means of the elasticity of the spiral cables 6 are pressed and forced to rotate towards the inner side of the back of the smartphone attachment plate 4 and finally fixed at the bending position of the smartphone attachment plate 4, in this way, the smart phone 7 can be connected to the smart phone attachment plate 4 and even the entire industrial and civil microphones relatively firmly, and as shown in fig. 3, the ring hinge frame 7022 cannot move up and down to the adjacent through hole, so the vertical height position of the smart phone 7 relative to the smart phone attachment plate 4 is fixed, and further, the user can hold the smart phone more easily. Of course, the user can also use the feature that the spiral cable 6 can be stretched to push out the spiral cable 6 from between the smartphone attachment plate 4 and all the tie bars 5 when pushing the ring 7021 and the ring hinge rack 7022 into the overlapping via array 402 or pulling the ring and the ring hinge rack 7022 out of the overlapping via array 402, and as before, the user can further force the four fingers or palms to be inserted between the spiral cable 6 and all the tie bars 5 to hold the smartphone 7 around the smartphone attachment plate 4 and the spiral cable 6 and operate the smartphone 7 with the thumb of the same hand. Of course, the industrial and domestic microphones provided by the present invention can be used as usual, as described above, provided that the user's back of the phone is not equipped with a finger ring attachment. Referring to all the drawings of the specification except fig. 2, without loss of generality, the thickness of the thin sheet of the smartphone attachment plate 4 may be set to be not more than one millimeter, so that the ring 7021 can also be easily bent toward the smartphone attachment plate 4 after passing through the smartphone attachment plate 4 so thin as to hook the smartphone 7 onto the smartphone attachment plate 4 and even the entire industrial and civil dual-purpose microphone. In specific implementation, the size of the through holes of the overlapped through hole array is relatively easy to determine, because the inventor finds that the size specification of the lower smart phone finger ring buckle is basically consistent after investigation, for example, the outer diameter of the cylindrical ring hinge frame is generally eight millimeters, and the thickness of the ring is not more than five millimeters, so that the requirement of the above function can be met by setting the diameter of the through holes to be nine to ten millimeters and setting the minimum distance between the overlapped parts of the through holes to be less than eight millimeters. In addition, the smart phone backup plate 4 is actually a simple sheet metal part, and can be blanked and formed by a stamping die at one time, so that the production and manufacturing cost is very low, the selling price is also very low, even if the outer diameter sizes of a plurality of finger ring hinge frames need to be matched, overlapped through hole arrays with different apertures can be completely manufactured for consumers to select when the consumers purchase the microphones, and the selection is called as different 'packages' in the current popular Taobao network shopping, and almost the common knowledge is already known. However, it is said that the overlapped through hole array punched or cut directly on the sheet metal is advantageous and disadvantageous, because it is troublesome for the user to adjust the up-down position of the smart phone, and it may be necessary to push the elastic adhesive tape with the other hand to pull the smart phone with the ring hinge frame and the ring out of a through hole of the overlapped through hole array to adjust the up-down position and then push the ring hinge frame into another through hole of the corresponding height position, so the "hard hole" type overlapped through hole array 402 of the first embodiment has a space for further optimization and improvement; of course, it is necessary for a user who has experienced a relatively large number of times in using the product of the present invention to count which of the through holes of the overlapping through hole array the finger ring buckle of his smartphone is suitable for being inserted into.

In the present invention, referring to all the figures except fig. 2, the spiral cable 6 needs to smoothly realize the five functions, except that the outer diameter is large enough to occupy the space of the gap 9 between the smartphone attachment plate 4 and all the connecting rods 5, and the spiral cable 6 needs to be ensured to be located in the gap 9 between the smartphone attachment plate 4 and all the connecting rods 5 as far as possible, as a preferred and optimized technical solution of the present invention based on the above technical solution, as shown in fig. 4, in the second embodiment of the present invention, the smartphone attachment plate 4 is equipped with an elastic cable tie 404 facing the connecting rods 5 and the inner side of the back of the spiral cable 6, and the cable tie 404 is inserted into most of the spiral turns of the spiral cable 6 as shown in fig. 4, the cable tie 404 thus ties the spiral cable 6 to the center of the inside of the back of the smartphone attachment plate 4 along the length of the smartphone attachment plate 4. The elastic cable tie 404 can effectively keep the spiral cable 6 always between the smartphone attachment plate 4 and all the connecting rods 5 as much as possible, thereby successfully realizing the five functions of the spiral cable. Note that while FIG. 4 also illustrates an elastic band, generally designated 403, in the above-described embodiment of the second embodiment the elastic band 403 is not incorporated into the second embodiment.

As a technical solution further optimized on the above-mentioned optimized technical solution, in order to facilitate the user to apply the integral pressing compression to the spiral cable 6 when inserting the ring 7021 and the ring hinge frame 7022 into the overlapped through hole array, as a second embodiment of the second embodiment, as shown in fig. 4 and referring to fig. 3, an elastic abutting belt 403 is closely attached to the back inner side surface of the smartphone leaning plate 4 facing the connecting rod 5 and the spiral cable 6, an elastic cable tie 404 for binding the spiral cable 6 is fastened to one side surface of the elastic abutting belt 403 facing the spiral cable 6, and the elasticity of the elastic abutting belt drives the elastic abutting belt 403 to always keep the tendency not to deviate from the inner side surface of the smartphone leaning plate 4. When a user inserts the ring 7021 and the ring hinge frame 7022 of the smart phone back finger ring buckle accessory into the overlapped through hole array, the user can easily grasp all the connecting rods 5 and the spiral cables 6 with one hand, and then lift the elastic attachment band 403 with the fingertips and press the spiral cables 6 through the elastic attachment band 403, so as to smoothly force the elastic attachment band 403 to become flat and smoothly enter the back inner side of the smart phone attachment plate 4. In addition, the elastic attachment band 403 can press and bend the rotated ring 7021 together with the spiral cable 6 by its own elasticity to always keep the ring in close contact with the inner surface of the smartphone attachment plate 4, thereby ensuring reliable connection between the smartphone 7 and the smartphone attachment plate 4.

In the present invention, as another optimized implementation manner of the above-mentioned overlapped through hole array, as shown in fig. 6, in a third embodiment of the present invention, a manner of generating the overlapped through hole array 402 on the smartphone attachment plate 4 is not to directly punch a hole or cut with a laser or plasma beam on the smartphone attachment plate 4, the overlapped through hole array 402 is to be located on a back surface of a straight groove 401 along a length direction of the smartphone attachment plate 4, and the overlapped through hole array 402 is composed of two spring steel wires 8 welded to the straight groove 401 toward a back surface of the spiral cable 6. That is, as shown in fig. 6, the smartphone attachment plate 4 has a straight groove 401 along its length direction, and two spring steel wires 8 soldered to the straight groove 401 toward the back of the spiral cable 6 constitute the overlapped through hole array 402. As shown in fig. 6, the two spring steel wires 8 have a bent structure forming the overlapping through-hole array 402; the width of the straight groove 401 is larger than the outer diameter of the ring hinge frame 7022, and the ring hinge frames 7022 extending into the overlapped through hole array 402 can be manually driven to overcome the elastic force of the spring steel wire 8 to prop the two-by-two overlapped parts of the through holes open so as to enter the adjacent through hole from one through hole. Referring to fig. 3, this facilitates the user to dynamically adjust the vertical height position of the smartphone 7 relative to the entire industrial and residential wireless microphone when using the present invention. Compared with the hard hole type overlapped through hole arrays of the first and second embodiments, the overlapped through hole array rich in elasticity of the third embodiment has good adaptability to ring buckles of smartphones with various sizes as long as the width of the straight groove 401 is controlled to enable the overlapped through hole array to accommodate the ring hinge frame. Note that it is entirely possible for the first and second embodiments to upgrade their respective "hard hole" type overlapping via arrays to such a resilient overlapping via array in the third embodiment.

Two scenarios can be imagined, if an industrial and civil microphone as shown in fig. 1, 5 and 6 is used, in the industrial field, as mentioned above, one hand can be used to hold and control the smart phone with the industrial distributed control APP software installed and simultaneously hold and use the industrial and civil microphone to signal workers in a remote workshop site, while the other hand can be used to freely hold tool equipment such as a wrench, a screwdriver and the like or control an instrument panel; in the civil entertainment field, a user can hold the smart phone 7 and the microphone which are not in the form of a film, the other hand is free, gestures can be carried out along with singing, friends of the user can be drawn, liquor can be drunk by the friends, and the like, and the situation that the user cannot smoothly do things if the user holds the smart phone in the other hand can be imagined.

Finally, it should be noted that the above-described embodiments are not intended to limit the embodiments of the present invention, and any modifications, equivalent replacements, and conventional improvements made within the technical principle of the technical solution provided by the present invention, such as attaching cushions to the inner side surfaces of all the connecting rods facing the spiral cable 6 and the inner side surfaces of the base 2 and the base 3 facing the spiral cable 6, or processing the inner side surfaces of the base 2 and the base 3 facing the spiral cable 6 into an ergonomic concave structure, should be included in the protection scope of the present invention as claimed in the claims.
