A capacitor C1 (100 nF) is connected between the Vin end and the GND, and the capacitor C1 is used for filtering out the noise of the input power, ensuring that the power input to the voltage stabilizing chip is relatively stable, and reducing the influence of the power supply ripple on the subsequent circuit.

A capacitor C2 (100 nF) is connected between the VOut end and the GND, and the 5V power output is further filtered to enhance the stability of the power supply.

[0016] The sound pickup module comprises a microphone, the first end of the microphone is connected with a bias circuit for providing a bias voltage, the bias circuit comprises at least one resistor, the first end of the microphone is connected with a direct current blocking circuit, the direct current blocking circuit comprises at least one capacitor, and the direct current blocking circuit is connected with the signal processing module. In combination Figure 1As shown, specifically, the microphone MK1 is in the lamp in a position capable of effectively receiving ambient sound. The first end of the microphone MK1 is connected to a biasing circuit composed of a resistor R6 with a resistance of 2.2KΩ, the first end of the resistor R6 is connected to the power supply V33, and the second end of the resistor R6 is connected to the first end of the microphone, providing a stable and suitable bias voltage for the microphone, ensuring that the microphone can work normally and accurately convert the sound signal into a weak electric signal. The first end of the microphone is also connected to a direct current blocking circuit composed of a capacitor C4 with a capacitance of 1uF, the first end of the capacitor C4 is connected to the first end of the microphone, and the second end of the capacitor C4 is connected to the signal processing module, which blocks direct current signals and only allows alternating current sound signals to pass through, avoiding interference from direct current components on subsequent circuits. The electric signal processed by the direct current blocking circuit is transmitted to the signal processing module. To ensure stable operation of the circuit, in the diagram, some configurations are also connected as follows: the second end of the microphone is grounded, the first end of the resistor R6 is connected to the first end of the resistor R2 with a resistance of 2.2KΩ, the first end of the resistor R3 with a resistance of 2.2KΩ, and the first end of the resistor R1 with a resistance of 33KΩ, the second end of the resistor R7 with a resistance of 68KΩ is connected to the second end of the resistor R2 and the first end of the resistor R5 with a resistance of 1KΩ, the second end of the resistor R3 is connected to the second end of the resistor R5, the first end of the capacitor C3 with a capacitance of 1uF, and the first end of the resistor R8 with a resistance of 2.2KΩ, the second end of the resistor R1 is connected to the first end of the resistor R4 with a resistance of 470KΩ, and the second end of the resistor R4 is connected to the second end of the capacitor C3 and the first end of the resistor R9 with a resistance of 120KΩ.

The collector of the transistor Q2 is connected to the second end of the resistor R1 and then to the power supply V33, the emitter is grounded, and the base and collector are connected to the second end of the capacitor C3. When the weak electric signal from the pickup module is input, the transistor amplifies the signal according to its own amplification characteristics, enhancing the strength of the signal for subsequent processing.

[0018] The control module is a microcontroller, which is provided with an ADC detection pin and a control signal output pin. The ADC detection pin is connected with the output end of the signal processing module, used for receiving the processed electrical signal and performing analog-to-digital conversion detection. The control signal output pin is connected with the LED display module, used for outputting a control instruction to drive the LED display module to work according to the detection result. In combination Figure 1 As shown, specifically, the control module adopts a microcontroller (MCU) with a dedicated ADC detection pin P35 / AN1 and a control signal output pin P34 / LED. The ADC detection pin is closely connected with the output end of the signal processing module. When the processed electrical signal is transmitted to the pin, the microcontroller uses its built-in ADC function to perform analog-to-digital conversion detection on the signal, quickly and accurately obtaining relevant characteristic parameters of the signal, such as the amplitude and frequency of the signal. According to these detection results, the microcontroller analyzes and processes them through the internal preset program algorithm, and sends corresponding control instructions to the LED display module through the control signal output pin to accurately control the working state of the LED display module, realizing intelligent regulation and control of the light effect. For example, in a music playing scene, when the music rhythm speeds up and the volume increases, the microcontroller detects the changes in signal amplitude and frequency, and according to the preset algorithm, outputs instructions to make the LED display module speed up the light flashing frequency, increase the light brightness, and expand the light-emitting area, so as to realize dynamic matching with the music rhythm and volume, and create a lively atmosphere. In particular, this technology (such as the preset program algorithm, intelligent regulation and control algorithm, etc.) can adopt any one of the existing technologies, and is not the content to be protected by the present application, therefore, this text will not be described here. The pins P30 / RX and P31 / TX of the microcontroller are used for serial communication with other devices to realize data transmission and interaction, such as receiving external control instructions or sending circuit state information; the pins P31 / TX, P35 / AN1 and P32 / IN2 are connected with the keys K1, K2 and K3 respectively, and the pin P01 / IN4 is connected with the collector of the transistor Q1. When the corresponding key is pressed, the level state of the corresponding pin will change, and the MCU will perform corresponding operations after detecting the level change to realize the man-machine interaction function. The resistor R12 with a resistance of 100Ω is connected with a plurality of fantasy color LED lamp beads, used for controlling the current size of the LED lamp beads, thereby adjusting the brightness and light-emitting color of the LED lamp beads, and controlling the bright and dark states of the LED lamp beads through the related pins of the MCU, so as to realize 3D display.

[0019] The LED display module includes a plurality of fantasy color LED lamp beads, which are arranged in a 3D light and shadow display layout on the lamp. The plurality of fantasy color LED lamp beads are connected with the control module. Figure 1As shown, in particular, the color-changing LED lamp beads (i.e. the LED lamp beads 1-6 shown in the figure) internally integrate light-emitting chips of different colors (such as red, green, blue, etc.), and through the combination of light-emitting chips of different colors, a rich variety of color effects can be presented. The light and shadow display layout refers to the arrangement of a plurality of LED lamp beads on the lamp according to a specific layout, such as a matrix, a ring, or a three-dimensional distribution, etc., to realize the presentation of 3D light and shadow effects. It is connected to the control pin of the MCU through the resistor R12. It can realize the separate control or combined control of LED lamp beads of different colors, and under the driving of the MCU, it presents a dazzling colorful light effect according to the change of the sound signal, creating a 3D visual atmosphere. For example, when a high-intensity low-frequency sound is detected, the red and yellow LED lamp beads are driven to flash at a high brightness, simulating the jumping effect of the flame; for high-frequency sound, the blue and green LED lamp beads are controlled to light up with a soft gradient effect, creating a lively atmosphere.

[0020] Working principle:

[0021] The microphone picks up the ambient sound, and the sound signal causes the capacitance change inside MK1, generating an alternating voltage signal related to the sound intensity and frequency. The signal is coupled to the circuit composed of transistors Q1 and Q2 through C4 capacitor;

[0022] When the alternating sound signal is input, in the positive half cycle of the sound signal, the base potential of transistor Q1 decreases, transistor Q2 is cut off, and the emitter level of transistor Q2 rises. This sudden change in level is coupled to the base of transistor Q1 through C3 capacitor, making transistor Q1 conduct, and the emitter of transistor Q1 becomes low. At this time, due to the charging characteristics of C3 capacitor, it will maintain the coupling level provided to the base of transistor Q1 to a certain extent, so that transistor Q1 can maintain a relatively stable conduction state in the positive half cycle of the sound signal, thereby ensuring effective amplification of the input signal; in the negative half cycle of the sound signal, the circuit state is reversed, but the charge accumulated by C4 capacitor during the positive half cycle begins to discharge, and its discharge current will affect the potential change of the base of transistor Q1, so that the low level of the emitter of transistor Q1 is maintained at a low level for a certain period of time. The accumulated low level time and amplitude are closely related to the intensity and frequency of the sound signal;

[0023] MCU uses 100 ms as a time slice to detect the level change value by using ADC. According to the detected low level time length and amplitude, MCU outputs control signals to drive the colorful LED lamp beads through P34 / LED pin after internal program processing. When the sound intensity is large and the frequency is low, the capacitor C4 discharges relatively slowly, and the low level time accumulated at the emitter of the transistor Q1 is longer and the amplitude is larger. MCU will recognize this feature after internal program processing, and output control signals to drive the colorful LED lamp beads through P34 / LED pin. For example, more red and yellow LED lamp beads may be driven to flicker at a high brightness and a low frequency, simulating the visual effect of low frequency and large energy such as flame jumping, so as to realize the close association and dynamic matching of sound signal characteristics and LED display effect, present the visual change of 3D stereoscopic effect, and realize sound and light synchronization.

[0024] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified to the technical solution recorded in the foregoing embodiments, or to replace some of the technical features, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the protection scope of the present application.
