[0036] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0037] It should be noted that: similar labels and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0038] The term "and / or" in this paper is only to describe a relationship, which means that there are three kinds of relationships, for example, A and / or B, which means that there are three kinds of situations, such as A alone, A and B together, and B alone.

[0039] Research has revealed that in-vehicle microphone lights have certain limitations in display modes. Most can only switch colors according to preset color playback modes, resulting in a relatively fixed and monotonous display mode. This fixed display mode cannot adjust the light display in real time according to changes in audio intensity and frequency, making it difficult to achieve more complex and diverse dynamic lighting effects. This makes it difficult to meet users' expectations for dynamic lighting effects, leading to a homogenization of user experience in different scenarios and affecting user satisfaction.

[0040] Based on the above research, this utility model provides a microphone control circuit, a vehicle microphone, and a car, which can achieve diverse lighting display effects.

[0041] The following detailed description, in conjunction with the accompanying drawings, describes the microphone control circuit, vehicle microphone, and automobile provided in the embodiments of this utility model.

[0042] See Figure 1 As shown, Figure 1 This is a schematic block diagram of a car provided for some embodiments of the present invention. The car 1000 includes an onboard microphone light 100.

[0043] The vehicle 1000 can include battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and gasoline-powered vehicles, without specific limitations. Furthermore, the type of vehicle 1000 is also not specifically limited; for example, it can be a sedan, bus, truck, or tractor-trailer.

[0044] Optional, see Figure 2 As shown, Figure 2 This is a schematic block diagram of a vehicle-mounted microphone light provided in some embodiments of the present invention. The vehicle-mounted microphone light 100 includes a housing (not shown), and a microphone light control circuit 10 is disposed inside the housing.

[0045] Optionally, the vehicle-mounted pickup light 100 may also include a Bluetooth connector, a wireless network connector, etc., which are not specifically limited here.

[0046] The following is a detailed description of the specific structure of the pickup lamp control circuit.

[0047] See Figure 3 As shown, Figure 3 This is a schematic block diagram of a microphone control circuit provided in some embodiments of the present invention. The microphone control circuit 10 includes a microphone module 11, multiple signal conversion modules 12, and multiple RGB LED groups 13.

[0048] In the present example, N signal conversion modules and N groups of fantasy light groups are taken as an example for illustration, where the specific value of N can be determined according to actual needs, which is not limited here. For example, N can take the value of 5, that is, the pickup lamp control circuit can include 5 signal conversion modules and 5 groups of fantasy light groups.

[0049] Specifically, the pickup module 11 is configured to collect audio information in the environment and generate a target audio signal after processing the audio information.

[0050] Each signal conversion module 12 is connected to the pickup module 11, configured to receive the audio signal output by the pickup module 11, and convert the audio signal into a corresponding display control signal according to the intensity of the audio signal.

[0051] The plurality of fantasy light groups 13 are connected to the plurality of signal conversion modules 12 one by one, each fantasy light group is configured to receive the display control signal output by the signal conversion module connected thereto, and control each fantasy light of the fantasy light group to display according to the received display control signal; wherein each fantasy light group includes a plurality of series-connected fantasy lights, and the number of fantasy lights included in different fantasy light groups can be the same or different.

[0052] In addition, the display colors of the fantasy lights included in different fantasy light groups can be the same or different, and the display colors of the fantasy lights included in the same fantasy light group can also be the same or different. For example, the fantasy light can be an RGB lamp bead, wherein RGB lamp is a light source that produces various colors of light through the combination of red (Red), green (Green), and blue (Blue) colors.

[0053] It can be understood that since each fantasy light group includes a plurality of series-connected fantasy lights, and in actual application, the plurality of series-connected fantasy lights often have a certain delay when transmitting the display control signal, and different fantasy light groups often have different speeds when transmitting the display control signal, so that the display effects of different fantasy light groups are different, and more complex and diversified light control and display effects can be achieved.

[0054] Optionally, each fantasy light in each fantasy light group is connected in series through a data line, and a power line and a ground line are needed for power supply. Each fantasy light can include an intelligent digital interface, a data latch, a signal shaping and amplifying driving circuit, and a high-precision internal oscillator and a programmable constant current control part. These internal circuit modules work together to ensure that the color of each pixel point is highly consistent, so that the final presented light color effect is more uniform and accurate.

[0055] In the data transmission process, each fantasy lamp needs a display control signal of, for example, 24-bit data to control its color and brightness, the display control signal is input through the input end of the first fantasy lamp, the first fantasy lamp extracts the 24-bit data of the display control signal and stores it in the internal data latch, and then forwards the remaining data to the next fantasy lamp through the output end, and the data is sequentially transmitted until all the fantasy lamps receive the data.

[0056] In some possible embodiments, the display control signal is a pulse width modulation (PWM) signal.

[0057] In this way, by changing the duty cycle of the pulse width modulation signal, the brightness of the pickup lamp can be accurately adjusted, and smooth transition of the light brightness can be realized, avoiding sudden brightness changes, so that the light effect is more natural and comfortable.

[0058] Please refer to Figure 4 , Figure 4 The principle block diagram of the pickup lamp control circuit provided by some other embodiments of the utility model. The pickup module 11 includes an audio detection unit 111 and an audio amplification circuit 112. Among them, the audio detection unit 111 is used to detect audio information in the environment and convert the detected audio information into an audio signal output; the audio amplification circuit 112 is connected with the audio detection unit 111 and is used to amplify the audio signal to obtain the target audio signal.

[0059] Exemplarily, the audio detection unit 111 is a microphone.

[0060] In this way, the audio detection unit 111 can sensitively capture the audio information in the environment, and even if the original audio information in the environment is weak, the target audio signal can be ensured to maintain sufficient strength in the transmission and processing process through the audio amplification circuit.

[0061] Optionally, referring again to Figure 4 , the plurality of signal conversion modules include a main signal conversion module 121, and the main signal conversion module 121 is further used to generate an audio control signal in response to a user instruction signal.

[0062] The pickup module 11 further includes an audio control circuit 113, which is connected between the main signal conversion module 121 and the audio amplification circuit 112 and is used to generate an audio processing signal in response to the audio control signal, and the audio processing signal is used to control the audio amplification circuit 112 to amplify the audio signal.

[0063] The user instruction signal can be a voice instruction of the user, a gesture or posture instruction of the user, or an instruction of a key triggered by the user, and the like.

[0064] In this way, the audio control signal can be generated in response to the user instruction signal, the audio processing signal can be generated through the audio control circuit, and the working of the audio amplification circuit can be controlled through the feedback of the audio processing signal to the audio amplification circuit, so that the user's personalized audio control is realized, and the participation of the user is improved.

[0065] In some possible implementation manners, referring back to Figure 4 , the sound pickup lamp control circuit 10 further comprises a key module 14, the key module 14 is connected with the main signal conversion module 121, and the key module 14 is configured to generate the user instruction signal in response to a triggering operation of the user.

[0066] For example, the key module 14 can include a touch key or a manually pressed key.

[0067] In this way, the user can generate the corresponding user instruction signal through a simple triggering operation, without a complex operation process or learning cost, so that the sound pickup lamp can be controlled, such as on-off control and mode switching, to meet the personalized needs of different users.

[0068] Referring back to Figure 4 , the plurality of signal conversion modules further comprise a plurality of slave signal conversion modules 122, and the main signal conversion module 121 is further configured to generate a trigger signal; each slave signal conversion module 122 is connected with the main signal conversion module 121, and each slave signal conversion module 122 is configured to work synchronously in response to the trigger signal.

[0069] Here, the main signal conversion module 121 is specifically configured to generate the trigger signal in response to the user instruction signal.

[0070] In this way, the trigger signal generated by the main signal conversion module 121 can ensure that each slave signal conversion module 122 works synchronously, so that the delay in the signal processing process is reduced, the transmission and processing of the target audio signal between different slave signal conversion modules are performed at the same time, and the overall efficiency of the sound pickup lamp control circuit is improved.

[0071] In order to more intuitively show the working principle of the sound pickup lamp control circuit 10, refer to Figure 5 , Figure 5 is a circuit principle schematic view of the audio detection unit and the audio amplification circuit provided by some embodiments of the utility model. As shown in Figure 5As shown in the figure, the audio detection unit 111 comprises a microphone MIC, a first capacitor C1 and a first resistor R1, and the audio amplification circuit 112 comprises an operational amplifier U1, a second capacitor C2, a third capacitor C3, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5 and a sixth resistor R6.

[0072] The first connecting end (pin 1) of the microphone MIC is connected with the inverting input end (pin 3) of the operational amplifier U1 through the first capacitor C1 and the second resistor R2, and the second connecting end (pin 2) of the microphone MIC is connected with the ground end (GND1).

[0073] Here, the first capacitor C1 functions as a direct current blocking capacitor, which prevents direct current signals from entering the subsequent circuit and allows the audio alternating current signals generated by the microphone MIC to pass through, and then the audio alternating current signals reach the inverting input end of the operational amplifier U1 through the second resistor R2.

[0074] Optionally, the first connecting end (pin 1) of the microphone MIC can also be connected with the power supply VDD through the first resistor R1, so as to limit the current passing through the microphone MIC, avoid burning the internal elements of the microphone MIC due to excessive current, thereby protecting the microphone MIC, and through voltage division of the first resistor R1, a relatively stable working voltage can be provided for the microphone MIC, so that the microphone MIC can work at a more suitable voltage, which helps to improve the performance and stability of the microphone MIC.

[0075] Among them, the fifth resistor R5 and the sixth resistor R6 constitute a voltage dividing circuit to provide a stable direct current bias voltage for the non-inverting input end (pin 1) of the operational amplifier U1.

[0076] The amplification multiple of the audio amplification circuit 112 is determined according to the feedback network composed of the second resistor R2 and the third resistor R3, and the amplification multiple is about 1 plus the ratio of the third resistor R3 to the second resistor R2.

[0077] After the amplification processing, the target audio signal (MIC signal) is output from the output end (pin 4) of the operational amplifier U1 and then transmitted to each signal conversion module through the fourth resistor R4.

[0078] Please refer to Figure 6 , Figure 6 The circuit principle schematic diagram of the key module, the main signal conversion module and the audio control circuit provided by some embodiments of the utility model. As shown in the figure, Figure 6 As shown in the figure, the key module 14 comprises a mechanical switch K1.

[0079] In this way, the trigger operation of the mechanical switch can provide instant tactile feedback, so that the user can clearly know whether the operation is triggered, and the user's interactive experience is enhanced.

[0080] The main signal conversion module 121 comprises an analog-to-digital converter U2, a fourth capacitor C4, and a seventh resistor R7.

[0081] The audio control circuit 113 comprises an electronic switch Q1, and a control end of the electronic switch Q1 is connected with the main signal conversion module 121.

[0082] In the present example, a Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) is used as the electronic switch, and in other examples, other elements can also be used as the electronic switch, such as a Bipolar Junction Transistor (BJT), an Insulated Gate Bipolar Transistor (IGBT), etc.

[0083] The audio control circuit 113 further comprises an eighth resistor R8 and a ninth resistor R9.

[0084] When the mechanical switch K1 is pressed, the circuit is turned on, and the user instruction signal (KEY signal) is generated, and the KEY signal is transmitted to the analog input end (pin 2) of the analog-to-digital converter U2. The analog-to-digital converter U2 generates an audio control signal in response to the KEY signal.

[0085] The audio control signal is output from the pin 6 of the analog-to-digital converter U2, and is input to the gate of the electronic switch Q1 through the eighth resistor R8. Here, the eighth resistor R8 is used to transmit the voltage of the input audio control signal to the gate of the electronic switch Q1, and at the same time, the eighth resistor R8 also has a certain current limiting effect. One end of the ninth resistor R9 is connected to the gate (pin 1) of the electronic switch Q1, and the other end is grounded, providing an initial low level for the gate of the electronic switch Q1, so that the electronic switch Q1 remains in the off state when there is no input signal.

[0086] The electronic switch Q1 is in an off state or a conductive state.

[0087] For the off state, when there is no external signal input to the gate of the electronic switch Q1 connected through the eighth resistor R8, due to the effect of the ninth resistor R9, the gate voltage of the electronic switch Q1 is close to 0V, at this time, the drain and source of the electronic switch Q1 are in an off state, and almost no current can pass through.

[0088] For the on state, when a high enough voltage signal is applied to the gate of the electronic switch Q1 through the eighth resistor R8, the electronic switch Q1 is turned on, a low resistance state is presented between the drain and the source of the electronic switch Q1, and current can flow from the drain (pin 3) to the source (pin 2) of the electronic switch Q1, realizing the on state of the circuit. The control of the audio amplification circuit 112 is realized by the on and off of the electronic switch Q1.

[0089] It can be understood that when the electronic switch Q1 is in the on state, the electronic switch Q1 generates an audio processing signal (GD signal) in response to the audio control signal, which is described again with reference to Figure 5 , the GD signal passes through the third capacitor C3 and reaches pin 5 of the operational amplifier U1, and the audio amplification circuit 112 works. Correspondingly, when the electronic switch Q1 is in the off state, the audio amplification circuit 112 does not work.

[0090] When the electronic switch Q1 is in the on state, the audio amplification circuit 112 works, and the target audio signal (MIC signal) obtained after amplification processing is output from the output end (pin 4) of the operational amplifier U1 and transmitted to each signal conversion module through the fourth resistor R4. In this example, it is transmitted to the analog input end (pin 5) of the operational amplifier U1.

[0091] After processing by the analog-to-digital converter U2, a display control signal (PWM signal) is generated, which is transmitted to the corresponding color-changing lamp group through the first output end (pin 7) of the analog-to-digital converter U2 and the seventh resistor R7, ensuring that the display control signal can be stably transmitted to the subsequent circuit module and preventing signal distortion caused by excessive current or impedance mismatch.

[0092] The analog-to-digital converter U2 also generates a trigger signal (KI signal), which is transmitted to each of the slave signal conversion modules 122 through the second output end (pin 3) of the analog-to-digital converter U2.

[0093] It can be understood that the circuit structure of the slave signal conversion module 122 is similar to that of the master signal conversion module 121, and will not be described again here.

[0094] In some possible embodiments, referring to Figure 7 , the principle block diagram of the pickup lamp control circuit provided by some embodiments of the present application is shown. Figure 7 The pickup lamp control circuit 10 further includes a gear display module 15, and the gear display module 15 includes a plurality of gear indicator lights. Different gear indicator lights correspond to different gears of the automobile.

[0095] In practical applications, different gear indicator lights correspond to gears of the vehicle, such as P, R, N, S+, S-, etc.

[0096] Specifically, the gear display module 15 is configured to receive a gear signal of the vehicle and control a gear indicator light corresponding to a current gear of the vehicle to be turned on according to the gear signal.

[0097] In this way, by adding the gear display module 15 in the pickup light control circuit 10, the current gear information is directly displayed through the gear indicator light, which helps the driver quickly understand the gear state of the vehicle and enhances the driving safety.

[0098] Optionally, the pickup light control circuit 10 further comprises a power conversion circuit 16 configured to process a supply voltage of an external power supply received to supply power to each circuit element.

[0099] It can be understood that the gear display module 15 shares the power supply and ground with other elements in the pickup light control circuit 10.

[0100] Specifically, referring to Figure 8 , Figure 8 the power conversion circuit of some embodiments of the utility model provides a circuit principle diagram. As shown in Figure 8 , the power conversion circuit 16 comprises a power management chip U3 having a voltage conversion function, an inductor L1, a fifth capacitor C5, a sixth capacitor C6, a seventh capacitor C7, an eighth capacitor C8, a ninth capacitor C9, a tenth resistor R10, an eleventh resistor R11 and a twelfth resistor R12.

[0101] The charging and discharging process of the inductor L1 is controlled by the switch circuit inside the power management chip U3, so as to realize the conversion from the 12V input voltage to the target output voltage. When the internal switch of the power management chip U3 is turned on, the current is stored through the inductor L1; when the internal switch of the power management chip U3 is turned off, the inductor L1 releases energy to maintain the stability of the output voltage.

[0102] The input voltage "IN / 12V" first passes through a filter circuit composed of the sixth capacitor C6 and the seventh capacitor C7, a voltage dividing circuit composed of the eleventh resistor R11 and the twelfth resistor R12, monitors the output voltage in real time, and transmits the feedback signal to the power management chip U3. The power management chip U3 adjusts the switch action inside the power management chip U3 according to this feedback information, so as to stabilize the output voltage and ensure that the "VCC / 5V" output terminal can provide a stable 5V voltage.

[0103] The pickup lamp control circuit, the vehicle-mounted pickup lamp and the automobile provided by the embodiment of the utility model, since multiple signal conversion modules are arranged in the pickup lamp control circuit and connected with the pickup module, one fantasy light group is connected with each signal conversion module, so that the pickup lamp can be controlled to change correspondingly through the audio intensity in the environment, so that the pickup lamp can change the display mode in real time and synchronously with the change of the audio intensity, for example, if the audio intensity frequently changes from weak to strong or from strong to weak, multiple display effects of gradual change of each fantasy light group from more to less or from less to more can be realized, and the different fantasy light groups include multiple series fantasy lights with same or different quantity, so that the display effects of different fantasy light groups are different, more complex and diversified light control and display effects can be realized, the expectation of dynamic light effect of the user is met, and the experience of the user is improved.

[0104] It can be understood that the structure of the embodiment of the utility model does not constitute a specific limitation of the pickup lamp control circuit, the vehicle-mounted pickup lamp and the automobile. In other embodiments of the utility model, the pickup lamp control circuit, the vehicle-mounted pickup lamp and the automobile can include more or fewer components than the illustration, or combine certain components, or split certain components, or different component arrangements. The illustrated components can be implemented in hardware, software or a combination of software and hardware.

[0105] In addition, each of the above modules can include a corresponding circuit or chip, etc. In the present embodiment, the specific circuit of each module is not limited, as long as each module can realize the corresponding function. In addition, each module can be integrated on the same circuit substrate and arranged in the same housing, or can be integrated on different circuit substrates and arranged in different housings. The specific combination can be made according to the actual situation, and no specific limitation is made here.
