[0029] EMBODIMENT
[0030] As Figure 1 shown, a sound box lamp effect control system includes lamp beads / lamp strips, and further includes an audio signal amplification module, a controller and a first connector, the audio signal amplification module is connected with the controller, the controller is connected with the first connector, and the first connector is used to be connected with the lamp beads / lamp strips. The audio signal amplification module is used to amplify the audio signal of a sound source and send to the controller, the controller is used to receive the amplified audio signal, and based on the amplitude and frequency of the audio signal, a preset lamp effect adjustment instruction is called, the controller sends the preset lamp effect adjustment instruction to the lamp beads through the first connector, and the controller adjusts at least one of the color, brightness, flicker frequency and light-on sequence of the lamp beads / lamp strips through the preset lamp effect adjustment instruction.
[0031] Among them, the lamp bead is the commonly used RGBLED lamp bead with chip in the prior art, and the lamp strip is a plurality of RGBLED lamp beads connected in series.
[0032] By reference, the preset lamp effect adjustment instruction is shown in the following table:
[0033]
[0034] In this embodiment, the audio signal amplification module amplifies the input audio signal, and the amplified audio signal is transmitted to the controller. The controller analyzes the received audio signal and selects an appropriate lighting effect adjustment command based on the amplitude and frequency of the audio signal. As shown in the table above, these commands are pre-set and correspond to different equivalent modes. The controller sends the selected lighting effect adjustment command to the LED beads / LED strips through the first connector. After receiving the command, the LED beads / LED strips change parameters such as color, brightness, flashing frequency, and lighting sequence according to the command requirements, thereby producing the corresponding lighting effect.
[0035] For reference, such as Figure 2 and Figure 3 As shown, the audio signal amplification module includes a first capacitor C409, a first resistor R404, a second resistor R405, a second capacitor C410, a third resistor R406, a transistor Q401, a third resistor R407, and a fourth resistor R409.
[0036] One end of the first capacitor C409 is connected to one end of the first resistor R404, and the other end of the first resistor R404 is connected to the second capacitor C410. The second resistor R405 is connected in parallel between the first resistor R404 and the second capacitor C410. One end of the third resistor R406 is connected to the base of the transistor Q401, and the other end of the third resistor R406 is connected to the collector of the transistor Q401. The other end of the third resistor R406 is connected to one end of the fourth resistor R409. The other end of the fourth resistor R409 is connected to the controller U403.
[0037] The other end of the first capacitor C409 is grounded. When the audio signal is input to the audio signal amplification module, the first capacitor C409 is used to filter out noise in the audio signal to avoid noise interference affecting the performance of the amplifier.
[0038] The first resistor R404 can be either an adjustable resistor or a fixed resistor.
[0039] In one possible application scenario, a vertical light strip is arranged on the surface of the sound box, and the light effect to be achieved is that when the volume of the sound box changes from small to large, the lamp beads on the light strip light up from the bottom to the top, and as the volume changes, the light on the light strip will have a jumping effect, when the volume is the largest, the light jumping amplitude is the highest, and when the volume is the smallest, the light starts from the bottom of the light strip. In this application scenario, the first resistor R404 can be set as a fixed resistor, and the resistance value of the first resistor R404 is 5.1KΩ, which allows a higher voltage gain. This means that even a small change in the audio signal can be significantly amplified by the audio signal amplification module, making the light more sensitive to changes in sound. In this case, the light can start when the volume is small, and when the volume is the largest, the light can be very bright and even "jump to the top of the sound box", that is, the light effect reaches the strongest state.
[0040] In another possible implementation, the first resistor R404 can be an adjustable resistor, such as Figure 2 As shown, the resistor R404 is marked as "470R / 5K1", which means that the resistance can be adjusted between 470 ohms (Ω) and 5.1 kilohms (kΩ), so as to adapt to different models of sound boxes.
[0041] It should be noted that the second resistor R405, the third resistor R406, the third resistor R407 and the fourth resistor R409 are all bias resistors.
[0042] Among them, as Figure 2 shown, the model of the controller U403 is CA51F152S1. The 6th pin of the controller is connected with the fourth resistor.
[0043] For reference, as Figure 2 and Figure 4 shown, it further includes a second connector CN405 and a third connector CN403, the first connector CN404 is connected with the 2nd pin of the controller U403, the second connector CN40 is connected with the 3rd pin of the controller U403, and the third connector CN403 is connected with the 5th pin of the controller U403; the first connector CN404, the second connector CN405 and the third connector CN403 are used to connect different lamp beads / light strips.
[0044] In this embodiment, the audio signal is input from the sound source to the audio signal amplification module. The first capacitor C409 filters out the noise in the audio signal, and the triode Q401 amplifies the input audio signal. The amplified signal is transmitted to the controller U403, which receives the amplified audio signal and calls the preset light effect adjustment instructions based on the amplitude and frequency of the signal. These instructions include different light effect modes, such as rainbow right rotation, starlight, rainbow spectrum movement, etc.
[0045] By reference, as shown in Figure 2 With Figure 4 As shown, the first pin and the eighth pin of the controller are connected to the programmable port CN406. This allows external devices (such as programmers or debugging tools) to program, firmware update or debug the controller. This makes the system flexible to update and modify the control logic to adapt to different application scenarios and needs.
[0046] By reference, as shown in Figure 2 It also includes a fourth connector CN402 for connecting with the front-end power amplifier module of the sound box and the Bluetooth chip of the sound box; the second pin of the fourth connector CN402 is connected with the audio signal amplification module; the third pin of the fourth connector CN402 is connected with the first pin of the controller. The front-end power amplifier module or the Bluetooth chip sends instructions to the third pin of the fourth connector CN402, and the controller will change the mode of the lamp beads / lamp strips, changing 1-10 modes.
[0047] In this embodiment, two ways to start or change the light and sound effect mode are provided. One is to generate an audio signal through the front-end power amplifier module, and the audio signal is input to the audio signal amplification module. The first capacitor C409 filters out the noise in the audio signal, and the triode Q401 amplifies the input audio signal. The amplified signal is transmitted to the controller U403, which receives the amplified audio signal and calls the preset light effect adjustment instructions based on the amplitude and frequency of the signal, to realize the adjustment of the light effect mode. The second is that the Bluetooth chip in the sound effect can send instructions directly to the controller U403 through the third pin of the fourth connector. These instructions can be specific light mode selection, brightness adjustment, color change, etc. The controller U403 receives the instructions from the Bluetooth chip through the third pin of the fourth connector. According to these instructions, the controller U403 will immediately change the mode of the lamp beads / lamp strips, changing 1-10 preset light effect modes.
[0048] The controller U403 sends preset light effect adjustment instructions to the corresponding lamp beads / lamp strips through the first connector CN404, the second connector CN405 and the third connector CN403. The lamp beads / lamp strips adjust the color, brightness, flicker frequency and light-on sequence according to the received instructions. For example, the user can send instructions through a mobile phone or other Bluetooth devices to select different light modes, such as rainbow right rotation, starlight, rainbow spectrum wandering, etc.
[0049] The controller U403 sends preset light effect adjustment instructions to the corresponding lamp beads / lamp strips through the first connector CN404, the second connector CN405 and the third connector CN403. The lamp beads / lamp strips adjust the color, brightness, flicker frequency and light-on sequence according to the received instructions. For example, the user can send instructions through a mobile phone or other Bluetooth devices to select different light modes, such as rainbow right rotation, starlight, rainbow spectrum wandering, etc.
[0050] In summary, in this embodiment, the audio signal output by the preamplifier module contains the frequency component and intensity information of the music. These signals are alternating signals that change over time, reflecting the rhythm, volume and frequency characteristics of the music. The triode Q401 amplifies the input audio signal, making it easier for the controller U403 to detect changes in the signal. After receiving the amplified audio signal, the controller U403 analyzes the amplitude (i.e. volume) and frequency characteristics of the signal, and based on the amplitude and frequency of the signal, the controller U403 calls the preset light effect adjustment instructions. For example, when the signal amplitude increases (indicating an increase in volume), the controller may increase the brightness of the lights or change the color of the lights; when the signal frequency is high (indicating high-frequency music), the controller may cause the lights to flash quickly. In this way, the light effect changes in synchronization with the rhythm and intensity of the music, enhancing the user's audio-visual experience. For example, at low frequency beats, the lights can flash slowly; at high frequency melodies, the lights can change color or brightness quickly.
[0051] The user can also send instructions to the controller U403 through the fourth connector through a mobile phone or other Bluetooth devices to select different light modes. These instructions can directly control the color, brightness, flicker frequency, etc. of the lights. 1-10 different light effect modes can be preset to meet the needs of different users. For example, the user can select modes such as rainbow right rotation, starlight, rainbow spectrum wandering, etc.
[0052] As Figure 2 With Figure 5 As shown in the figure, it can be understood that it also includes a power module U402 connected to the controller U403. The power module U402 can output a 5-volt DC power supply to power the controller U403.
[0053] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
