[0027] Reference Figures 1 to 7The application discloses a portable microphone connecting structure, which comprises an upper combined section 1 and a lower combined section 2, the upper combined section 1 is provided with a clamping piece one, the lower combined section 2 is provided with a clamping piece two, the clamping piece two is a clamping column 5, the clamping piece one is a clamping groove, the clamping piece one can be clamped with the clamping piece two to connect the upper combined section and the lower combined section together, specifically, the upper combined section 1 comprises an upper shell 3, the lower combined section 2 comprises a lower shell 4, the clamping column 5 is arranged on the lower shell 4, the clamping groove is arranged on the upper shell 3, and a contact electric connection structure is arranged between the upper combined section and the lower combined section, so that the microphone circuit in the lower combined section is also communicated with the microphone circuit in the lower combined section, the contact electric connection structure is a metal contact and a metal contact piece, when the clamping column is clamped with the clamping groove, the metal contact and the metal contact piece are also in contact, so that the microphone circuit in the lower combined section is communicated with the microphone circuit in the lower combined section, of course, the clamping piece one and the clamping piece two of the application can also be other structures, for example, a clamping hook and a clamping groove are clamped, or a clamping hook and a clamping block are clamped, etc. The two parts can be disassembled through the above structure, and it is very convenient to carry, when the microphone is needed, the two parts are combined, the microphone is electrically connected with the circuit on the circuit board, and then the microphone can be used. However, the power supply of the above microphone system is always connected, only the microphone is not connected to the circuit on the circuit board, when the two parts of the microphone are combined, the microphone is suddenly connected to the circuit, the system power supply will generate a pulse signal to the microphone, which causes the microphone to emit a harsh noise when being combined, and affects the user experience.
[0028] As another connecting structure of the application, the upper combined section 1 and the lower combined section 2 can adopt a threaded connection structure, an inner thread / outer thread is arranged on the upper combined section 1, and an outer thread / inner thread is arranged on the lower combined section 2, which can also realize the contact connection of the metal contact and the metal contact piece while connecting the upper combined section 1 and the lower combined section 2.
[0029] In order to further solve the above problems, in the present application, the upper combination section 1 and the lower combination section 2 have a combination state of being combined with each other, a pre-combination state of being separable from each other, and a separation state of being completely separated from each other. In the separation state, the upper combination section 1 and the lower combination section 2 are completely not in contact, and are two independent individuals. The upper combination section 1 and the lower combination section 2 are butted to make them enter the pre-combination state, in which the upper combination section 1 and the lower combination section 2 have been in contact but are not locked, and are easily separated under the action of an external force, being a separable state. The lower combination section 2 is movable relative to the upper combination section 1 to freely switch between the combination state and the pre-combination state. In the combination state, the upper combination section 1 and the lower combination section 2 are combined and connected, at this time, they are combined into an integrated structure, and are difficult to separate under the action of an external force, and the lower combination section 2 and the upper combination section 1 can only be separated from each other by switching from the combination state to the pre-combination state. The lower combination section 2 can have multiple movement modes relative to the upper combination section 1 to freely switch between the combination state and the pre-combination state, for example, plug-in movement or rotation.
[0030] The specific structure is: therefore, the clamping groove includes a vertical section 6 and a transverse section 7. One end of the vertical section 6 is in communication with the outside to facilitate the entry of the clamping column 5. When the lower shell 4 is inserted into the upper shell 3, the clamping column 5 is clamped into the vertical section 6 and moved to the bottom end of the vertical section 6, at this time, the upper combination section 1 and the lower combination section 2 are in the pre-combination state, and then rotated to make the clamping column 5 clamped into the end of the transverse section 7, thereby ensuring that the clamping column 5 cannot be easily removed, at this time, the upper combination section 1 and the lower combination section 2 are in the combination state of being combined and connected with each other. Of course, in order to make the transverse section 7 clamp the clamping column 5 more tightly, the groove width of the transverse section 7 gradually narrows from one end in communication with the vertical section 6 to the other end, so that the clamping column 5 will be clamped more tightly during movement in the transverse section 7. Moreover, the clamping column 5 is a cylinder, and the upper shell 3 and the lower shell 4 are both cylinders, so that the upper shell 3 and the lower shell 4 can maintain consistency in appearance no matter how they are rotated. The threaded connection structure and the clamping structure have the same principle, both of which are clamped during rotation, at the same time, the upper combination section 1 and the lower combination section 2 are in the combination state of being combined and connected with each other. Of course, the threaded connection structure requires that the metal contact be preferably a flexible metal contact, which is also a very common component that can be purchased externally, so the structure is not described in detail.
[0031] As shown in the figure, in particular, the lower shell 4 includes an outer connector 8 and a cylindrical shell 9, the outer connector 8 is inserted into the lower shell 4 at one end and fixed with the lower shell 4; the upper shell 3 includes a cylindrical shell 10 and an inner connector 11 fixed in the cylindrical shell 10, the clamping column 5 is located on the outer wall of the outer connector 8, and the clamping groove is located on the inner wall of the inner connector 11, the part of the outer connector 8 exposed outside the cylindrical shell 9 can be inserted into the inner connector 11 and make the clamping column 5 and the clamping groove clamped, the cylindrical shell 9 and the cylindrical shell 10 are made of metal, and the outer connector 8 and the inner connector 11 are made of plastic, because it is difficult and costly to set the clamping groove or the clamping column 5 on the metal, we use the combination of plastic and metal, because plastic can be injection molded into complex shapes, and if pure plastic is used, it will have the defects of not being beautiful and not being durable.
[0032] The outer connector 8 includes a connecting cylinder 12, the diameter of the connecting cylinder 12 is greater than the diameter of the outer connector 8, and the connecting cylinder 12 is located in the cylindrical shell 9; the end of the inner connector 11 is provided with a convex ring 13, and the end of the cylindrical shell 10 abuts against the convex ring 13. The purpose of the above structure is to be able to position during installation, so that the outer connector 8 can ensure the depth of insertion into the cylindrical shell 9 through the connecting cylinder 12, and the cylindrical shell 10 can also ensure the position of the inner connector 11 in the cylindrical shell 10 through the abutment with the convex ring 13.
[0033] As a specific structure of the threaded connection structure: in this application, the inner wall of the inner connector 11 is provided with an internal thread, and the outer wall of the outer connector 8 is provided with an external thread, of course, the clamping column 5 and the clamping groove are cancelled, so as to realize the same function of the clamping column 5 and the clamping groove through the rotation of the internal thread and the external thread.
[0034] As shown in the figure, the end of the outer connector 8 is provided with a circular groove 27, the battery compartment is arranged at the bottom of the groove 27, the battery compartment is two circular holes, the battery cover 30 is located in the groove 27 and the buckle structure is arranged between the battery cover 30 and the groove 27, of course, in order to save materials, the bottom end of the outer connector 8 is provided with a fixing seat 15, the fixing seat 15 includes a partition plate 28 and a supporting plate 29 connected vertically with the partition plate 28, the supporting plate 29 is provided with a spring and a contact piece respectively at both ends to contact the battery, so that the outer connector 8 does not have to be longer than the battery, thereby saving materials.
[0035] As shown in the figure, the buckle structure includes elastic buckling blocks 31 arranged on the side edge of the battery cover 30 and buckle holes (not shown in the figure) arranged on the inner wall of the groove 27. The elastic buckling blocks 31 can be buckled into the buckle holes. The elastic buckling blocks 31 can not only be buckled into the buckle holes, but also can be deformed under pressure to separate from the buckle holes when the battery cover 30 is pulled out. Considering that the hole on the outer connecting head 8 is not beautiful enough, a limiting block is arranged on the inner wall of the groove 27. The buckle hole is surrounded by the limiting block and the wall of the groove 27.
[0036] As shown in the figure, the battery cover 30 is further provided with an elastic plate 32. The elastic plate 32 has a gap with the battery cover 30. The elastic buckling blocks 31 are arranged on the elastic plate 32. In this way, the elastic buckling blocks 31 can be buckled into or out of the buckle holes through the bending deformation of the elastic plate 32. Of course, the elastic buckling blocks 31 can also be made of soft rubber to achieve the purpose of being buckled into or out of the buckle holes through deformation. However, the structure of the elastic plate 32 is still the best choice.
[0037] As shown in the figure, the side edge of the battery cover 30 is provided with a positioning block (not shown in the figure). The inner wall of the groove 27 is provided with a limiting block (not shown in the figure) for limiting the positioning block. The battery cover 30 is fixed by the positioning block and the buckling block, so as not to be pulled out of the groove 27. The groove 27 is provided with two vertical columns 33. The battery cover 30 is provided with two positioning holes matched with the two vertical columns 33. In this way, the battery cover 30 cannot rotate and be pulled out of the groove 27. Metal elastic probes are arranged in the corresponding vertical columns 33, respectively. The two first conductive contacts 211 and the two second conductive contacts 212 are the contact ends of the metal elastic probes exposed through the through holes on the vertical columns 33.
[0038] In the above structure, the power source is a battery. The installation of the battery is achieved by the buckling and separation of the battery cover 30 and the groove 27 to realize the installation or replacement of the battery. Moreover, after the two parts of the microphone are combined, the battery cover 30 can be hidden in the microphone shell, so that the battery cover 30 cannot be seen in appearance, and the overall structure looks beautiful. Moreover, after the outer connecting head 8 and the inner connecting head 11 are buckled tightly, the battery cover 30 will be pressed, so that the battery cover 30 will not be bounced out when falling.
[0039] As Figure 10As shown, the contact electric connection structure is that: the first electric conductor 111, the second electric conductor 112 and the third electric conductors 113 are arranged on the upper combined section 1 and separated from each other, so that there is no electric connection between the first electric conductor 111, the second electric conductor 112 and the third electric conductors 113. Specifically, the first electric conductor 111, the second electric conductor 112 and the third electric conductors 113 are metal conductive pieces on a circular circuit board 14 arranged on the bottom surface of the inner hole of the inner connecting head 11. Among them, the third electric conductors 113 can be one or more according to actual conditions. The microphone is used to obtain sound signals, generally has two wiring ends, the first electric conductor 111 and the second electric conductor 112 are respectively used for electrically connecting with the two wiring ends of the microphone. The two first electric contact points 211 and the two second electric contact points 212 are arranged on the lower combined section 2, and the two first electric contact points 211 and the two second electric contact points 212 are located on the end surface of the outer connecting head 8, so that when the outer connecting head 8 is inserted into the inner connecting head 11, the electric contact points and the electric conductors will be in contact. The microphone naturally has a microphone circuit, which can be a conventional circuit in the existing microphone. Since the audio signal generated by the microphone needs to be obtained, the microphone circuit naturally needs to be provided with two audio input ports, and at the same time, the microphone circuit needs to be powered to work, which has a power input end for electrically connecting with the power supply 23. The two first electric contact points 211 are respectively used for electrically connecting with the two audio input ports of the microphone circuit, and the two second electric contact points 212 are respectively used for electrically connecting with the power supply 23 and the power input end of the microphone circuit. Therefore, the two first electric contact points 211 need to be electrically connected with the first electric conductor 111 and the second electric conductor 112 respectively, so as to connect the microphone into the microphone circuit, so that the microphone circuit can obtain the audio signal generated by the microphone. And the two second electric contact points 212 must be electrically connected, so that the power supply 23 can supply power to the microphone circuit, and the microphone circuit can work, thereby realizing the corresponding function of the microphone circuit.
[0040] In the embodiment, the two first conductive contacts 211 are always in contact with the first and second conductive bodies 111 and 112 respectively, and the two audio input ports of the microphone circuit are electrically connected to the two wire ends of the microphone respectively during the free switching between the combined state and the pre-combined state of the upper combined section 1 and the lower combined section 2. When the upper combined section 1 and the lower combined section 2 are in the pre-combined state, the two second conductive contacts 212 are disconnected, and the power supply 23 does not supply power to the microphone circuit. When the upper combined section 1 and the lower combined section 2 are in the combined state, the two second conductive contacts 212 are in contact with the same third conductive body 113, and the two second conductive contacts 212 are electrically connected, and the power supply 23 supplies power to the microphone circuit. In other words, the switching function is realized by whether the two second conductive contacts 212 are in contact with the same third conductive body 113. Therefore, when the microphone is combined, the electrical connection time of the microphone and the microphone circuit is earlier than the time when the power supply is connected to the microphone circuit. In this way, the pulse noise generated when the microphone is combined can be effectively eliminated, and the user experience is improved.
[0041] In an embodiment, the upper combined section 1 and the lower combined section 2 are arranged to realize the free switching between the combined state and the pre-combined state by rotating the lower combined section 2 relative to the upper combined section 1. That is, when the two are in the pre-combined state, the lower combined section 2 can be rotated relative to the upper combined section 1 to the combined state, and when the two are in the combined state, the lower combined section 2 can be rotated relative to the upper combined section 1 to the pre-combined state.
[0042] For this connection structure, the corresponding first and second conductive bodies 111 and 112 are concentrically arranged as circular rings, and the third conductive body 113 is an arc segment concentrically arranged with the first conductive body 111. Therefore, the first, second and third conductive bodies 111, 112 and 113 are concentrically arranged, and the straight line distance between the two ends of the third conductive body 113 should be greater than or equal to the distance between the two second conductive contacts 212, so that the two second conductive contacts 212 can be electrically connected to the same third conductive body 113.
[0043] In the process of rotating the lower combined section 2 relative to the upper combined section 1 from the pre-combined state to the combined state, the rotating paths of the two first conductive contacts 211 coincide with the first conductive body 111 and the second conductive body 112 respectively, so that in the process of state switching, one of the first conductive contacts 211 is always in contact with the first conductive body 111, and the other first conductive contact 211 is always in contact with the second conductive body 112, so that the microphone is always connected to the microphone circuit. At the same time, the rotating paths of the two second conductive contacts 212 coincide with the circular ring where the third conductive body 113 is located, so that the two second conductive contacts 212 can be rotated to contact the same third conductive body 113, and at least one second conductive contact 212 is not in contact with the third conductive body 113 when the upper combined section 1 and the lower combined section 2 are in the pre-combined state, so that the circuit between the two second conductive contacts 212 is disconnected.
[0044] In an embodiment, the upper combined section 1 and the lower combined section 2 are both cylindrical, and the lower combined section 2 can be inserted into the upper combined section 1 and can be rotated relative to the upper combined section 1. The lower combined section 2 is first inserted into the upper combined section 1, and the two are in a pre-combined state. The lower combined section 2 can be further rotated relative to the upper combined section 1 to a combined state.
[0045] Further, specific structures will be provided for the upper combined section 1 and the lower combined section 2 to realize free switching between the combined state and the pre-combined state through rotation.
[0046] With the foolproof structure design, the user can dock the card column 5 with any one of the card slots to combine the upper combined section 1 and the lower combined section 2, which is convenient for the user to use. At the same time, a plurality of third conductive bodies 113 are also provided, and the adjacent two third conductive bodies 113 are spaced apart by a predetermined distance, so that the user can dock the card column 5 with any one of the card slots to realize the switching function of the second conductive contact 212 contacting or not contacting the same third conductive body 113. When the upper combined section 1 and the lower combined section 2 are in the pre-combined state, at least one second conductive contact 212 is located between the adjacent two third conductive bodies 113, and the circuit between the two second conductive contacts 212 is disconnected.
[0047] In an embodiment, the first conductive contact 211 and the second conductive contact 212 described above can both be elastic contacts, so as to ensure that the conductive contacts can still stably contact the corresponding conductive bodies during the relative rotation of the upper combined section 1 and the lower combined section 2.
[0048] In an embodiment, as shown in Figure 6 the third conductive body 113 is arranged between the first conductive body 111 and the second conductive body 112, the radius of the first conductive body 111 is greater than the radius of the second conductive body 112, and the first conductive body 111 is arranged at the periphery of the third conductive body 113.
[0049] In one embodiment, the lower combined section 2 is provided with a fixing seat 15, and the power supply 16 is fixed on the fixing seat 15, and the fixing seat 15 is integrally connected with the lower combined section 2.
[0050] The following will provide a combined microphone applying the combined microphone contact type electric connection structure of the above embodiments, the upper shell 1 is provided with a microphone 18, the lower shell 2 is provided with a power supply 16 and a control circuit board 26, and the control circuit board 26 is provided with a control microphone circuit. The other end of the upper shell 1 is provided with a metal mesh head 17 covering the microphone 18.
[0051] The following will provide a specific circuit diagram of the control microphone circuit, as shown in Figure 8 and Figure 9 The control microphone circuit includes a control module and a power management module electrically connected with the control module, and the control module has an audio input port electrically connected with two first conductive contacts 211 respectively, and two second conductive contacts 212 are electrically connected with the power supply 16 and the input end of the power management module respectively. The power supply 16 transmits a power supply signal to the power management module, and the power management module processes the power supply signal and then transmits it to the control module, so that the control module works.
[0052] In one embodiment, the control module includes a wireless microphone chip and a wireless communication module electrically connected with the wireless microphone chip. As shown in Figure 9 The wireless microphone chip can be a BK95 series chip with 32 pins. The 15th and 16th pins of the wireless microphone chip are two audio input ports, and the two pins are electrically connected with two first conductive contacts 211 respectively, and the two pins can also be connected with an LC filter circuit. The wireless communication module in this application includes a Bluetooth chip and an antenna, and the 10th and 11th pins of the wireless microphone chip are connected with the antenna because the Bluetooth chip is integrated in the wireless microphone chip. Thus, the audio signal can be sent to a mobile phone or other mobile terminal through the antenna.
[0053] In one embodiment, as shown in Figure 8 The power management module includes a boost unit and a filter unit. The boost unit can be a ME2188 chip, which has DC-DC conversion function and boost function, and the 2nd pin is the input end and the 3rd pin is the output end, and finally the VBAT port outputs the power supply signal, and the pin of the wireless microphone chip requiring power supply is the power input end of the control microphone circuit. The positive pole of the battery is electrically connected with one of the second conductive contacts 212, and the other second conductive contact 212 can be electrically connected with the 2nd pin of the ME2188 chip. The filter unit can be a filter capacitor.
[0054] In summary, during the process of switching between the combined state and the pre-combined state of the upper combined section 1 and the lower combined section 2, the two first conductive contacts 211 are always in contact with the first conductive body 111 and the second conductive body 112, respectively, that is, the microphone is always electrically connected to the control microphone circuit, when the upper combined section 1 and the lower combined section 2 are in the pre-combined state, the two second conductive contacts 212 are disconnected, and the power supply 16 does not supply power to the control microphone circuit, when the upper combined section 1 and the lower combined section 2 are in the combined state, the two second conductive contacts 212 are in contact with the same third conductive body 113, at this time, the power supply 16 supplies power to the control microphone circuit. That is, when the microphone is combined, the electrical connection time of the microphone to the control microphone circuit is earlier than the time when the power supply 16 is connected to the control microphone circuit, so that the pulse noise generated when the microphone is combined can be effectively eliminated, and the user experience is improved.
