[0045] In order for those skilled in the art to better understand the present scheme, the technical solutions in the embodiments of the present scheme will be clearly described below in combination with the drawings in the embodiments of the present scheme. Obviously, the described embodiments are part of the embodiments of the present scheme, not all. Based on the embodiments in the present scheme, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present scheme.
[0046] The term "include" and other any variants thereof in the specification and claims of the present scheme and the above-mentioned drawings means "include but not limited to", which is intended to cover non-exclusive inclusion, and is not limited to the examples listed in the text. In addition, the terms "first" and "second" and the like are used to distinguish different objects, not to describe a specific order.
[0047] The implementation of the present disclosure will be described in detail below in combination with specific drawings:
[0048] Figure 1 is a structural schematic diagram of a report podium microphone light control box provided by an embodiment of the present disclosure. Referring to Figure 1 , the report podium microphone light control box includes a brightness adjustment module, a color temperature adjustment module, a first controller and a color temperature indicator light module.
[0049] The first controller is connected with the brightness adjustment module and the color temperature adjustment module respectively. The color temperature adjustment module is connected with the color temperature indicator light module.
[0050] The brightness adjustment module is configured to generate a brightness adjustment signal and transmit the brightness adjustment signal to the first controller, and the color temperature adjustment module is configured to generate a color temperature adjustment signal and transmit the color temperature adjustment signal to the first controller.
[0051] The indicator light module is configured to indicate the light information of the light supplement module on the microphone.
[0052] In the embodiment, the reporting podium microphone light control box is used to control the light effect of the light supplement module on the reporting podium microphone through wireless transmission. The reporting podium microphone includes a plurality of microphone units arranged on a base, the plurality of microphone units are arranged in sequence along the length direction of the base, the housings of the microphone units on the two sides are provided with light supplement windows, the light supplement windows face the base, and the light supplement lamps (i.e. the light supplement modules) are arranged in the light supplement windows.
[0053] In the embodiment, the brightness adjustment module is used to generate a brightness adjustment signal, so that the brightness of the light supplement module on the microphone can be adjusted according to actual needs. The color temperature adjustment module is used to generate a color temperature adjustment signal, so as to change the color temperature of the light supplement module on the microphone. Two knobs (a brightness knob and a color temperature knob) are arranged on the reporting podium microphone light control box, the brightness knob is connected with the brightness adjustment module, and the color temperature knob is connected with the color temperature adjustment module. The user can manually control the two knobs to adjust to a suitable light effect.
[0054] The first controller is used to receive the brightness adjustment signal and the color temperature adjustment signal transmitted by the brightness adjustment module and the color temperature adjustment module, process and analyze the signals, transmit the processed brightness adjustment signal and color temperature adjustment signal to the second controller on the reporting podium microphone through the wireless communication module, and the second controller receives the brightness adjustment signal and the color temperature adjustment signal to control the color temperature and the brightness of the light supplement lamp. The color temperature indicator light module can indicate the current light color temperature information of the microphone light supplement module in an intuitive way (such as different colors or brightness changes), so that the user can quickly understand the current color temperature state and facilitate further adjustment. The color temperature indicator light module can be installed on the surface of the control box.
[0055] For example, the user rotates the brightness knob corresponding to the brightness adjustment module to change the resistance value of the internal circuit, thereby generating a corresponding brightness adjustment signal, and transmitting the brightness adjustment signal to the first controller.
[0056] The user rotates the color temperature knob corresponding to the color temperature adjustment module to change the resistance value of the internal circuit, thereby generating a corresponding color temperature adjustment signal, and transmitting the color temperature adjustment signal to the first controller.
[0057] After receiving the brightness adjustment signal and the color temperature adjustment signal, the first controller analyzes and processes the signals and uses them to control the light supplement module on the podium microphone. At the same time, the color temperature adjustment module transmits the color temperature adjustment signal to the color temperature indicator light module, so that the indicator light displays the current color temperature state in a specific way (such as color change).
[0058] For example, in the reporting session of an academic seminar: the conference organizer places the microphone on the podium and turns on the light control box. Since the seminar environment is relatively bright, the organizer first adjusts the brightness to a lower level through the brightness adjustment module to avoid strong light interference with the speaker and the audience. At the same time, considering the seriousness of the academic occasion, the color temperature is adjusted to a higher value (cold color temperature) through the color temperature adjustment module to create a focused and professional atmosphere. At this time, the color temperature indicator light module displays the current cold color temperature state, such as displaying blue.
[0059] As the meeting progresses, the outdoor light gradually weakens, and the speaker finds that the light is too dark and the content on the manuscript is not clear. Therefore, the staff increases the brightness through the brightness adjustment module, and the first controller receives the brightness adjustment signal to wirelessly control the brightness of the microphone light supplement module, so that the speaker can clearly read the manuscript.
[0060] During the intermission, the staff considers that the atmosphere of the second half of the meeting can be slightly relaxed, and adjusts the color temperature to be lower (adjusts to the warm color temperature direction) through the color temperature adjustment module. The color temperature indicator light module changes the display accordingly, such as changing to orange, which intuitively reflects the color temperature change. When the second half of the meeting begins, the speaker reports under the warm color temperature light, which gives people a more friendly and relaxed feeling, which helps to relieve the fatigue of the audience.
[0061] From the above, it can be concluded that through the two independent knobs of brightness and color temperature, the user can conveniently and accurately control the light to meet the diverse needs of light in different scenarios, provide suitable light for the speaker, ensure that the manuscript is clear and visible, and improve the fluency of the speech. At the same time, it brings comfortable visual experience to the audience and avoids discomfort caused by strong light stimulation or dim light.
[0062] The color temperature indicator light module of the present embodiment presents the color temperature state in real time, so that the user can quickly understand and further fine-tune, realizing efficient human-computer interaction.
[0063] The present embodiment uses wireless transmission, which eliminates the constraints of cables, not only facilitating installation and arrangement, but also improving the flexibility of operation. The staff can control the light effect at any time within a certain range to ensure the smooth progress of the reporting activity.
[0064] As shown in FIG. 1, Figure 2 In one embodiment of the present disclosure, the color temperature adjustment module includes:
[0065] resistor R10 and slide rheostat RP3.
[0066] The first end of the resistor R10 is used for connecting the power supply VCC, and the second end of the resistor R10 is connected with the first end of the slide rheostat RP3 and the first controller respectively. The second end of the slide rheostat RP3 is used for grounding.
[0067] In the embodiment, the user rotates the adjusting end of the slide rheostat RP3 to change the resistance value of RP3, and the voltage division of the resistor R10 and RP3 changes according to the series voltage division principle. The voltage division is input as a color temperature adjusting signal into the first controller. The first controller generates a corresponding control signal according to the signal, and controls the color temperature of the microphone light compensation module.
[0068] For example, in a product release meeting of a company, the staff arranges the microphone on the rostrum before the meeting starts. Initially, the slide rheostat RP3 is adjusted to an appropriate position, so that the signal generated by the voltage division corresponds to a high color temperature, and a bright and cold light is created, which is suitable for a formal business occasion. As the meeting enters the product demonstration stage, the staff rotates RP3 to reduce the voltage division, so that the signal received by the first controller changes, and the color temperature of the microphone light compensation module is adjusted to a lower value, so that the audience has a softer visual experience, and the product features are highlighted better.
[0069] The color temperature of the microphone light compensation module can be adjusted more conveniently by the simple operation of the slide rheostat in the embodiment.
[0070] As shown in FIG. 6, in one embodiment of the present disclosure, the brightness adjusting module comprises: Figure 2
[0071] The resistor R11 and the slide rheostat RP4.
[0072] The first end of the resistor R11 is used for connecting the power supply VCC, and the second end of the resistor R11 is connected with the first end of the slide rheostat RP4 and the first controller respectively. The second end of the slide rheostat RP4 is used for grounding.
[0073] In the embodiment, when the user operates the slide rheostat RP4, the resistance value of RP4 changes, and the voltage division of the resistor R11 and RP4 changes according to the series voltage division principle. The voltage division is input as a brightness adjusting signal into the first controller. The first controller generates a corresponding control instruction according to the received signal, and sends the control instruction to the light compensation module on the microphone, so as to adjust the brightness of the light compensation module.
[0074] For example, in a school academic lecture, the microphone is placed on the podium, and the light control box is turned on. At the beginning, the staff adjusts the slide rheostat RP4 to a position where the voltage division is low, so that the brightness of the microphone light compensation module is low, and the bright light does not affect the projection screen of the lecture. As the lecture enters the question and answer session, the faces of the questioners and the speakers need to be illuminated more clearly, and the staff can operate the slide rheostat RP4 to increase the resistance value, so that the voltage division is increased, and the first controller receives a higher voltage signal, thereby controlling the microphone light compensation module to increase the brightness, so that everyone can see each other's facial expressions and actions, and ensure the smooth progress of the interactive session.
[0075] The embodiment can more conveniently adjust the brightness of the microphone light compensation module through the slide rheostat RP4
[0076] As shown in the figure, in one embodiment of the present disclosure, the color temperature indicating light module comprises: Figure 3
[0077] The first end of the resistor R12 is connected with the second end of the resistor R10, and the second end of the resistor R12 is connected with the first end of the MOS tube Q5.
[0078] The second end of the MOS tube Q5 is used for connecting the power supply VDD, and the third end of the MOS tube Q5 is connected with the first end of the indicating light LED3.
[0079] The second end of the indicating light LED3 is used for grounding.
[0080] In the embodiment, the resistor R12 is connected between the resistor R10 and the MOS tube Q5, and plays a role of signal transmission and current regulation. The MOS tube Q5 is used as a voltage-controlled element for amplifying and switching circuit signals. The second end of the MOS tube Q5 is connected with the power supply VDD to obtain electric energy, and the third end is connected with the indicating light LED3, which controls the indicating light LED3 by controlling its conduction or cut-off. The indicating light LED3 is used for directly displaying the light information of the microphone light compensation module, such as the color temperature state. The second end of the indicating light LED3 is grounded to form a loop, and the first end is connected with the MOS tube Q5, which is installed on the surface of the light control box, so as to facilitate the user to view.
[0081] In the embodiment, the resistor R10 transmits the color temperature adjustment signal from the color temperature adjustment module to the resistor R12, and the resistor R12 adjusts the current and then transmits it to the MOS tube Q5. When the color temperature adjustment signal makes the MOS tube Q5 conduct, the power supply VDD supplies power to the indicating light LED3 through the MOS tube Q5, and the LED3 is bright, indicating the color temperature state.
[0082] In the embodiment, the resistor R10 transmits the color temperature adjustment signal from the color temperature adjustment module to the resistor R12, and the resistor R12 adjusts the current and then transmits it to the MOS tube Q5. When the color temperature adjustment signal makes the MOS tube Q5 conduct, the power supply VDD supplies power to the indicating light LED3 through the MOS tube Q5, and the LED3 is bright, indicating the color temperature state.
[0083] This embodiment uses resistor R12, MOSFET Q5, and indicator LED3 to visually display the color temperature adjustment signal. Accurate indication is achieved with a simple circuit, allowing users to quickly understand the color temperature status of the microphone's supplementary lighting module, thus improving operational convenience and the user experience.
[0084] like Figure 4 As shown, in one embodiment of this disclosure, the reporting platform microphone lighting control box further includes a surge protection module, which includes:
[0085] Capacitor C2, resistor R13, op-amp U1, resistor R14, resistor R15, MOSFET Q6, resistor R16, and inductor L1.
[0086] The first terminal of capacitor C2 is used to connect to an external power supply, and the second terminal of capacitor C2 is used to ground.
[0087] The first end of capacitor C2 is connected to the first end of resistor R13, and the second end of resistor R13 is connected to the non-inverting input of operational amplifier U1 and the first end of resistor R14, respectively.
[0088] The second terminal of capacitor C2 is connected to the second terminal of resistor R14.
[0089] The inverting input of op-amp U1 is used to receive the reference signal REF, and the output of op-amp U1 is connected to the first end of resistor R15.
[0090] The second terminal of resistor R15 is connected to the first terminal of MOSFET Q6, the second terminal of MOSFET Q6 is connected to the first terminal of resistor R13, and the third terminal of MOSFET Q6 is connected to the first terminal of resistor R16 and the first terminal of inductor L1, respectively.
[0091] The second terminal of inductor L1 is connected to the second terminals of resistor R16 and resistor R14, respectively.
[0092] The second terminal of MOSFET Q6 is used to provide power supply VCC and power supply VDD.
[0093] In the embodiment, the external power supply is first connected to the capacitor C2, and the capacitor C2 functions as a filter to filter out high-frequency noise in the power supply. The resistor R13 and the resistor R14 form a voltage dividing circuit, and the voltage signal passing through the capacitor C2 is divided and input to the non-inverting input terminal of the operational amplifier U1, and the inverting input terminal of the operational amplifier U1 receives a reference signal REF. The operational amplifier U1 compares the signals at the non-inverting input terminal and the inverting input terminal, and outputs a signal according to the comparison result. The output signal is input to the first terminal of the MOS transistor Q6 through the resistor R15. When the operational amplifier U1 outputs a signal to trigger the MOS transistor Q6 to conduct, the power supply supplies power to the resistor R16 and the inductor L1 through the MOS transistor Q6. The inductor L1 generates a reverse electromotive force when the current changes, thereby suppressing sudden changes in current. The resistor R16 limits the current to a certain extent, and at the same time, the second terminal of the MOS transistor Q6 provides stable power supply VCC and VDD, ensuring that the power supply of the entire system is not affected by power surges.
[0094] For example, in some large meetings or event sites, due to the large number of electrical equipment in the venue, the power supply system may be unstable, such as the start and stop of high-power equipment may cause instantaneous voltage or current fluctuations, resulting in surges. At this time, the anti-surge module can play a role. When such fluctuations occur, the capacitor C2 in the anti-surge module filters out part of the noise, and the operational amplifier U1 controls the conduction state of the MOS transistor Q6 according to the comparison result of the reference signal REF and the divided voltage signal, and uses the characteristics of the inductor L1 to suppress sudden changes in current, and the resistor R16 limits the excessive current, finally provides stable power supply VCC and VDD, ensures the normal work of the report podium microphone light control box and its related equipment, avoids damage or abnormal work of the equipment caused by surges, and ensures the smooth progress of the activity.
[0095] The anti-surge module of the embodiment can effectively deal with the power supply problem of the report podium microphone light control box in a complex power environment. By filtering out high-frequency noise through the capacitor C2, the voltage dividing circuit cooperates with the operational amplifier U1 to accurately compare the signals, and the MOS transistor Q6, the inductor L1 and the resistor R16 work together to suppress sudden changes in current and limit excessive current, ensuring that the output stable power supply VCC and VDD. This not only ensures the normal operation of the light control box and related equipment, but also avoids damage to the equipment caused by surges, reduces the risk of interruption of the activity due to equipment failure, and effectively ensures the smooth progress of the activity.
[0096] In one embodiment of the present disclosure, the report podium microphone light control box further comprises:
[0097] A wireless communication module.
[0098] The wireless communication module is connected with the first controller.
[0099] The first controller is connected with the second controller on the microphone through the wireless communication module.
[0100] In the embodiment, the wireless communication module can use common wireless communication technologies such as Bluetooth, Wi-Fi, etc. Taking Bluetooth as an example, a Bluetooth chip needs to be integrated in the first and second controllers, a corresponding Bluetooth protocol stack needs to be configured, and pairing and communication rules need to be set.
[0101] In the embodiment, the first controller can process signals from the brightness adjustment module and the color temperature adjustment module, and send control instructions such as adjusting the brightness and color temperature of the light to the wireless communication module connected thereto. The wireless communication module encodes these instructions into wireless signals and transmits them through a specific frequency band. The second controller on the microphone is equipped with a corresponding receiving device, which decodes the wireless signals after capturing them, obtains instructions, and controls the light of the microphone accordingly. At the same time, the second controller can also transmit the state information of the microphone, such as the current brightness and color temperature of the light, to the first controller through the wireless communication module, realizing bidirectional communication.
[0102] For example, in a speech event, it may not be convenient to use wired connection due to personnel movement, equipment arrangement, and other factors. Before the speech, the speaker can use the wireless communication module to remotely adjust the brightness and color temperature of the light of the microphone through the operation interface on the light control box, to adapt to different speech scenes and personal needs, without the need for manual operation near the microphone, saving time and improving efficiency.
[0103] The wireless communication module of the embodiment significantly improves the convenience and flexibility of the report podium microphone light control. Users can remotely control the light to quickly adapt to different scene requirements. Bidirectional communication realizes real-time state feedback, facilitating precise control and greatly improving operation efficiency, providing an efficient and convenient light control experience for report activities.
[0104] In one embodiment of the present disclosure, the report podium microphone light control box further comprises:
[0105] A temperature sensor.
[0106] The temperature sensor is connected to the first controller.
[0107] In the embodiment, the report podium microphone light control box further comprises a refrigeration sheet.
[0108] The refrigeration sheet is connected to the first controller.
[0109] In this embodiment, the temperature sensor is used to monitor the temperature of the surrounding environment or the light control box, and transmit the measured temperature data in the form of an electrical signal to the first controller. The first controller processes and analyzes the received temperature signal, and when the temperature reaches or exceeds the preset critical value, it sends a start signal to the refrigeration sheet. After receiving the signal, the refrigeration sheet starts working, using its thermoelectric effect to transfer heat from one side to the other, thereby achieving the cooling function of the surrounding environment or the equipment in the control box. When the temperature drops to a safe range, the first controller will turn off the refrigeration sheet to avoid excessive cooling and energy waste.
[0110] For example, the temperature sensor can be placed near the key heat-generating areas inside the light control box, such as near the brightness adjustment module, color temperature adjustment module, first controller, etc. to accurately perceive the change in temperature. The temperature sensor can be a thermocouple, thermistor, or digital temperature sensor, which outputs temperature information to the first controller through analog or digital signals. The specific selection can be based on the system's requirements for temperature measurement accuracy and cost.
[0111] The refrigeration sheet is generally a semiconductor refrigeration sheet, which is connected to the output pin of the first controller. The first controller controls the on-off of the refrigeration sheet by controlling the level state of the output pin according to the set logic program. The refrigeration sheet can be installed inside the shell of the light control box and tightly attached to the heat-generating components, such as power circuit boards, electronic chips, etc. to effectively absorb and transfer the heat generated by these components.
[0112] For example, in a continuous international conference that lasts for several days, the microphone light control box on the reporting podium needs to work continuously for a long time. The internal electronic components of the light control box will generate a large amount of heat due to long-term operation, which may affect their performance or even damage the equipment. At this time, the temperature sensor will continuously monitor the temperature, and when the temperature rises to a certain level, for example, exceeds 40℃, the first controller will start the refrigeration sheet to remove the heat from the control box, ensuring that the internal components work within the appropriate temperature range and guarantee the stable operation of the microphone light system, avoiding problems such as light flickering, control failure, etc. caused by overheating, and ensuring the smooth progress of the conference. At the same time, when using the microphone light control box in a high-temperature environment, it can effectively avoid the impact of high ambient temperature on the equipment, providing a good temperature environment for the normal use of the equipment.
[0113] The temperature sensor of the embodiment monitors the temperature in real time, accurately feeds back data to the first controller, and ensures sensitive capture of temperature changes. The refrigeration sheet is started as needed, and timely heat dissipation is achieved to avoid overheating of electronic components due to long-time work or high-temperature environment. This not only ensures stable operation of the microphone light system, prevents light flickering, control failure and other faults, but also prolongs the service life of the equipment, and provides strong support for the smooth development of activities such as conferences.
