Description

Technical Field

[0001] This invention relates to the field of microphone technology, and in particular to a combined microphone contact-type electrical connection structure. Background Technology

[0002] As people's demand for audio equipment increases, audio devices are gradually developing towards intelligence and portability, making it easier for people to sing anytime, anywhere and enjoy the joy of music. Microphones have also evolved from simple sound pickup devices into multifunctional devices integrating speakers and other functional components. To facilitate the portability of microphones, a type of microphone has been introduced on the market that consists of two parts connected by a screw-on connector. One part contains the microphone capsule, and the other part contains the power supply and circuit board. Because the two parts are detachable, they are very convenient to carry. When the microphone is needed, the two parts are combined through the connector, and the microphone capsule is electrically connected to the circuit on the circuit board. However, in existing microphone systems, the power supply is always connected, only the microphone capsule is not connected to the circuit on the circuit board. When the two parts of the microphone are combined, the microphone capsule is suddenly connected to the circuit, and the system power supply generates a pulse signal to the microphone, causing the microphone to emit a harsh noise when combined, affecting the user experience. Summary of the Invention

[0003] This invention provides a combined microphone contact-type electrical connection structure, which can effectively eliminate pulse noise generated when microphones are combined and connected, thereby improving the user experience.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A combined microphone contact-type electrical connection structure includes a detachably connected first connector and a second connector. The first connector and the second connector have a combined state where they are connected to each other and a pre-combined state where they are separable from each other. The second connector can move relative to the first connector to freely switch between the combined state and the pre-combined state. The first connector is provided with a first conductor, a second conductor, and a plurality of third conductors that are separated from each other. Both the first conductor and the second conductor are used for electrical connection with the microphone head. The second connector is provided with two first conductive contacts and two second conductive contacts. The two first conductive contacts are used for electrical connection with the microphone circuit, and the two second conductive contacts are used for electrical connection with the power supply and the power input terminal of the microphone circuit, respectively. During the free switching between the combined state and the pre-combined state, the two first conductive contacts are always in contact with the first conductor and the second conductor, respectively. When the first connector and the second connector are in the pre-combined state, the two second conductive contacts are disconnected. When the first connector and the second connector are in the combined state, the two second conductive contacts are in contact with the same third conductor.

[0006] Preferably, the first and second connectors are configured to freely switch between a combined state and a pre-combined state by rotating the second connector relative to the first connector; the first and second conductors are concentrically arranged rings, and the third conductor is an arc segment concentrically arranged with the first conductor, and the straight-line distance between the two ends of the third conductor is greater than or equal to the distance between the two second conductive contacts; during the process of the second connector rotating relative to the first connector from the pre-combined state to the combined state, the rotation paths of the two first conductive contacts coincide with the first and second conductors respectively, and the rotation paths of the two second conductive contacts coincide with the ring where the third conductor is located, and when the first and second connectors are in the pre-combined state, at least one second conductive contact does not contact the third conductor.

[0007] Preferably, there are multiple third conductors, and there is a preset distance between two adjacent third conductors; when the first connector and the second connector are in a pre-assembled state, at least one second conductive contact is located between two adjacent third conductors.

[0008] Preferably, both the first connector and the second connector are cylindrical, and the second connector can be inserted into the first connector and can rotate relative to the first connector.

[0009] Preferably, the first connector is provided with a first fixing plate that is detachably connected to the first connector, the second connector is provided with a second fixing plate that is detachably connected to the second connector, the first conductor, the second conductor and the third conductor are all provided on the surface of the first fixing plate, and the two first conductive contacts and the two second conductive contacts are all provided on the surface of the second fixing plate.

[0010] Preferably, the first connector is provided with a fixing groove, and the first fixing plate is detachably fixed in the fixing groove by screws.

[0011] Preferably, the second fixing plate is snap-fitted to the second connector.

[0012] Preferably, the third conductor is disposed between the first conductor and the second conductor, and the radius of the first conductor is larger than the radius of the second conductor.

[0013] Preferably, the microphone circuit includes a control module and a power management module electrically connected to the control module. The control module has an audio input port that is electrically connected to two first conductive contacts, and two second conductive contacts that are electrically connected to the input terminals of the power supply and the power management module, respectively.

[0014] Preferably, the control module includes a wireless microphone chip and a wireless communication module electrically connected to the wireless microphone chip.

[0015] Preferably, the power management module includes a boost unit and a filter unit.

[0016] This invention offers the following technical advantages: The invention connects microphones via a first connector and a second connector. During the free switching between the combined and pre-combined states, the two first conductive contacts are always in contact with the first and second conductors, respectively, meaning the microphone is always electrically connected to the microphone circuit. When the first and second connectors are in the pre-combined state, the two second conductive contacts are disconnected, and power is not supplied to the microphone circuit. When the first and second connectors are in the combined state, the two second conductive contacts are in contact with the same third conductor, and power is then supplied to the microphone circuit. In other words, when assembling the microphones, the electrical connection between the microphone and the microphone circuit occurs earlier than the connection between the power supply and the microphone circuit. This effectively eliminates pulse noise generated during microphone assembly, improving the user experience. Attached Figure Description

Detailed Implementation

[0027] The electrical connection referred to in this invention means a direct electrical connection between two components or an indirect connection through intermediate components. The invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] This invention provides a combined microphone contact-type electrical connection structure, such as... Figure 1-3 As shown, it includes a detachably connected first connector 1 and second connector 2. The first connector 1 and second connector 2 have three states: a combined state where they are connected together, a pre-combined state where they are separable, and a completely separated state. In the separated state, the first connector 1 and second connector 2 are not in contact and are two independent entities. Connecting the first connector 1 and second connector 2 brings them into a pre-combined state. In this state, the first connector 1 and second connector 2 are in contact but not locked, and they are easily separated under external force, representing a separable state. The second connector 2 can move relative to the first connector 1 to freely switch between the combined state and the pre-combined state. In the combined state, the first connector 1 and second connector 2 are connected together, forming a single structure that is difficult to separate under external force. Furthermore, the second connector 2 and the first connector 1 can only be separated from each other by switching from the combined state to the pre-combined state. The second connector 2 can move relative to the first connector 1 in various ways to achieve the free switching between the combined state and the pre-combined state, such as by insertion or rotation.

[0029] The first connector 1 is provided with a first conductor 111, a second conductor 112, and several third conductors 113, which are separated from each other. Because they are separated, there is no electrical connection between the first conductor 111, the second conductor 112, and the third conductors 113. One or more third conductors 113 may be provided depending on the actual situation. The microphone is used to acquire sound signals and generally has two terminals. The first conductor 111 and the second conductor 112 are used to electrically connect to the two terminals of the microphone, respectively.

[0030] Two first conductive contacts 211 and two second conductive contacts 212 are provided on the second connector 2. The microphone naturally contains a microphone circuit, which can be a conventional circuit found in existing microphones. Since it needs to acquire the audio signal generated by the microphone, the microphone circuit naturally needs two audio input ports. Simultaneously, the microphone circuit requires power to operate and has a power input terminal for electrical connection with the power supply 23. The two first conductive contacts 211 are respectively used to electrically connect to the two audio input ports of the microphone circuit, and the two second conductive contacts 212 are respectively used to electrically connect to the power supply 23 and the power input terminal of the microphone circuit. Therefore, the two first conductive contacts 211 need to be electrically connected to the first conductor 111 and the second conductor 112 respectively to allow the microphone to be connected to the microphone circuit so that the microphone circuit can acquire the audio signal generated by the microphone. The two second conductive contacts 212 must be connected in a circuit for the power supply 23 to supply power to the microphone circuit, enabling the microphone circuit to operate and thus realize its corresponding functions.

[0031] In this embodiment, during the free switching between the combined state and the pre-combined state of the first connector 1 and the second connector 2, the two first conductive contacts 211 are always in contact with the first conductor 111 and the second conductor 112, respectively. The two audio input ports of the microphone circuit are then electrically connected to the two terminals of the microphone head. When the first connector 1 and the second connector 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. However, when the first connector 1 and the second connector 2 are in the combined state, the two second conductive contacts 212 are in contact with the same third conductor 113, the circuit between the two second conductive contacts 212 is connected, and the power supply 23 supplies power to the microphone circuit. This effectively achieves the switching function by checking whether the two second conductive contacts 212 are in contact with the same third conductor 113. Therefore, when combining the microphone, the electrical connection time between the microphone head and the microphone circuit is earlier than the connection time between the power supply and the microphone circuit. This effectively eliminates the pulse noise generated during microphone combination and connection, improving the user experience.

[0032] In one embodiment, the first connector 1 and the second connector 2 are configured to freely switch between a combined state and a pre-combined state by rotating the second connector 2 relative to the first connector 1. That is, when the two are in the pre-combined state, the second connector 2 can rotate relative to the first connector 1 to the combined state, and when the two are in the combined state, the second connector 2 can rotate relative to the first connector 1 to the pre-combined state.

[0033] In this connection structure, the first conductor 111 and the second conductor 112 are concentrically arranged rings, and the third conductor 113 is an arc segment concentrically arranged with the first conductor 111. Therefore, the first conductor 111, the second conductor 112 and the third conductor 113 are all concentrically arranged. At the same time, the straight-line distance between the two ends of the third conductor 113 should be greater than or equal to the distance between the two second conductive contacts 212. Only in this way can the two second conductive contacts 212 be electrically connected to the same third conductor 113.

[0034] During the rotation of the second connector 2 from the pre-assembled state to the assembled state relative to the first connector 1, the rotation paths of the two first conductive contacts 211 coincide with the first conductor 111 and the second conductor 112, respectively. Thus, during the state switching process, one of the first conductive contacts 211 is always in contact with the first conductor 111, and the other first conductive contact 211 is always in contact with the second conductor 112, ensuring the microphone is always connected to the microphone circuit. Simultaneously, the rotation paths of both second conductive contacts 212 coincide with the ring containing the third conductor 113. This allows both second conductive contacts 212 to rotate to contact the same third conductor 113. Furthermore, when the first connector 1 and the second connector 2 are in the pre-assembled state, at least one second conductive contact 212 is not in contact with the third conductor 113, thus disconnecting the circuit between the two second conductive contacts 212.

[0035] In one embodiment, both the first connector 1 and the second connector 2 are cylindrical. The second connector 2 can be inserted into the first connector 1 and can rotate relative to the first connector 1. The second connector 2 is first inserted into the first connector 1, and the two are in a pre-assembled state. The second connector 2 can then rotate relative to the first connector 1 to the assembled state.

[0036] Furthermore, a specific structure will be provided for the first connector 1 and the second connector 2 to freely switch between a combined state and a pre-combined state through rotation. For example... Figure 1-3As shown, the outer circumferential surface of the second connector 2 is provided with a protruding limiting post 22. The inner sidewall of the first connector 1 is provided with an axial groove 12 extending along the axial direction of the first connector 1 and a positioning groove 121 communicating with the axial groove 12. Both the axial groove 12 and the positioning groove 121 allow the limiting post 22 to move. The axial groove 12 extends all the way to the end face of the first connector 1. When the second connector 2 is inserted into the first connector 1, the limiting post 22 moves into the axial groove 12. One end of the positioning groove 121 communicates with the axial groove 12, and the other end moves away from the axial groove 12 along the circumference of the first connector 1. Therefore, the limiting post 22 must move from the positioning groove 121 to the axial groove 12 to separate from the first connector 1. When the limiting post 22 moves to the end of the positioning groove 121 that communicates with the axial groove 12, the first connector 1 and the second connector 2 are in a relaxed state. At this time, the limiting post 22 can move out of the axial groove 12 along the axial direction, so that the first connector 1 and the second connector 2 are separated. The limiting post 22 can also move circumferentially to the other end of the positioning groove 121. When the limiting post 22 moves to the end of the positioning groove 121 away from the axial groove 12, the first connector 1 and the second connector 2 are in a combined state.

[0037] In another embodiment, both the first connector 1 and the second connector 2 are cylindrical. The inner circumferential surface of the first connector 1 is provided with an internal thread, and the outer circumferential surface of the second connector 2 is provided with an external thread. The first connector 1 and the second connector 2 are connected axially by threads. The first conductive contact 211 and the second conductive contact 212 are both elastic contacts that can extend and retract axially. When the second connector 2 is screwed relative to the first connector 1 until the two first conductive contacts 211 are in contact with the first conductor 111 and the second conductor 112 respectively, the first connector 1 and the second connector 2 are in a pre-combined state. At this time, at least one second conductive contact 212 is not in contact with the third conductor 113. The second connector 2 can be further screwed on until the two second conductive contacts 212 are in contact with the same third conductor 113, at which point the first connector 1 and the second connector 2 are in a combined state.

[0038] To facilitate user operation, a limiting structure can be provided on the first connector 1 or the second connector 2. When the second connector 2 is screwed relative to the first connector 1 to the position of the limiting structure, the limiting structure prevents the second connector 2 from moving further inward relative to the first connector 1. The second connector 2 cannot be screwed further relative to the first connector 1, and at this point, the first connector 1 and the second connector 2 are in a combined state. This allows the user to know that the first connector 1 and the second connector 2 are combined and connected in place, without the need for further screwing. At the same time, it also ensures that when the first connector 1 and the second connector 2 are combined and connected in place, the first connector 1 and the second connector 2 are in a combined state, preventing the user from over-screwing and causing the two second conductive contacts 212 to not contact the same third conductor 113.

[0039] In one embodiment, multiple sets of the aforementioned limiting post 22, axial groove 12, and positioning groove 121 can be provided, employing a foolproof structural design. Users can connect the limiting post 22 to any one of the axial grooves 12 to combine the first connector 1 and the second connector 2, facilitating user operation. Simultaneously, multiple third conductors 113 are also correspondingly provided, with a preset distance between adjacent third conductors 113. Thus, by connecting the limiting post 22 to any one of the axial grooves 12, the user can achieve the switching function of the second conductive contact 212 being in contact with or not in contact with the same third conductor 113. Furthermore, when the first connector 1 and the second connector 2 are in a pre-combined state, at least one second conductive contact 212 is located between two adjacent third conductors 113, and the circuit between the two second conductive contacts 212 is broken.

[0040] In one embodiment, the first conductive contact 211 and the second conductive contact 212 described above can both be elastic contacts to ensure that the conductive contacts can still maintain stable contact with the corresponding conductors during the relative rotation of the first connector 1 and the second connector 2.

[0041] In one embodiment, a first fixing plate 11 detachably connected to the first connector 1 is provided inside the first connector 1, and a second fixing plate 21 detachably connected to the second connector 2 is provided inside the second connector 2. A first conductor 111, a second conductor 112, and a third conductor 113 are all disposed on the surface of the first fixing plate 11, and two first conductive contacts 211 and two second conductive contacts 212 are all disposed on the surface of the second fixing plate 21. This facilitates the installation, inspection, and maintenance of the first conductor 111, the second conductor 112, the third conductor 113, the first conductive contacts 211, and the second conductive contacts 212. The first conductor 111, the second conductor 112, and the third conductor 113 can all be conductive sheets fixed to the first fixing plate 11.

[0042] In one embodiment, such as Figure 7 As shown, a fixing groove 110 is provided in the first connector 1, and the first fixing plate 11 is detachably fixed in the fixing groove 110 by screws. The fixing groove 110 restricts the movement of the first fixing plate 11 and improves the stability of the fixation.

[0043] In one embodiment, the outer peripheral surface of the second fixing plate 21 is provided with a buckle, and the second fixing plate 21 is buckled to the second connector 2.

[0044] In one embodiment, such as Figure 3 As shown, the third conductor 113 is disposed between the first conductor 111 and the second conductor 112. The radius of the first conductor 111 is larger than the radius of the second conductor 112. The first conductor 111 is disposed around the third conductor 113.

[0045] In one embodiment, a fixing seat 24 is provided on the second connector 2, and the power supply 23 can be fixed on the fixing seat 24. The fixing seat 24 can be integrated with the second connector 2.

[0046] The following will provide a combined microphone that applies the contact-type electrical connection structure of the combined microphone in the above embodiments, such as... Figure 4-7 As shown, the first connector 1 is fixed to the first housing 100, and the second connector 2 is fixed to the second housing 200. The first housing 100 is equipped with a microphone 10, and the second housing 200 is equipped with a power supply 23 and a circuit board 26. The circuit board 26 is equipped with a microphone circuit.

[0047] In one embodiment, the first housing 100 may be cylindrical, the first connector 1 is disposed at one end of the first housing 100, and the other end of the first housing 100 is provided with a metal mesh head covering the microphone 10.

[0048] In one embodiment, the second housing 200 may be cylindrical, and a fixing seat 24 is provided inside the second housing 200. A circuit board 26 is fixed on the fixing seat 24, and the power supply 23 is a battery fixed on the fixing seat 24.

[0049] The following is a detailed circuit diagram of a microphone circuit, such as... Figure 8 and Figure 9 As shown, the microphone circuit includes a control module and a power management module electrically connected to the control module. The control module has audio input ports that are electrically connected to two first conductive contacts 211, and two second conductive contacts 212 that are electrically connected to the input terminals of the power supply 23 and the power management module, respectively. The power supply 23 sends a power signal to the power management module, which processes the power signal and then sends it to the control module to enable the control module to operate.

[0050] In one embodiment, the control module includes a wireless microphone chip and a wireless communication module electrically connected to the wireless microphone chip. For example... Figure 9 The wireless microphone chip can be a BK95 series chip with 32 pins. Pins 15 and 16 of the wireless microphone chip are two audio input ports, which are electrically connected to two first conductive contacts 211 respectively. These two pins can also be connected to an LC filter circuit. The wireless communication module includes an antenna, and pins 10 and 11 of the wireless microphone chip are connected to the antenna. This allows audio signals to be transmitted through the antenna.

[0051] In one embodiment, such as Figure 8As shown, the power management module includes a boost unit and a filter unit. The boost unit can be an ME2188 chip, which has DC-DC conversion and boost functions. Its pin 2 is the input terminal, pin 3 is the output terminal, and the power signal is finally output through the VBAT port. The pin that the wireless microphone chip needs to be powered is the power input terminal of the microphone circuit. The positive terminal of the battery is electrically connected to one of the second conductive contacts 212, and the other second conductive contact 212 can be electrically connected to pin 2 of the ME2188 chip. The filter unit can be a filter capacitor.

[0052] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention, but it should not be construed as limiting the specific implementation of the invention to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention.
