However, it is apparent to those skilled in the art that the utility model can be practiced without these specific details. In other embodiments, well-known structures, circuits, materials or methods are not specifically described in order to avoid obscuring the utility model.
[0034] EMBODIMENT
[0035] As Figure 1 shown, a system for controlling the lamp effect of a dual-mode sound box, comprising a first lamp strip, an audio signal amplification module, a controller, a first connector, a second connector, a third connector, a fourth connector, the input end of the audio signal amplification module is connected with the fourth connector, the output end of the audio signal amplification module is connected with the controller, the controller is connected with the first connector, the second connector, the third connector and the fourth connector respectively, and the first lamp strip is connected with the first connector or the second connector or the third connector.
[0036] The fourth connector is used to send the audio signal generated by the sound box front-end power amplifier module to the audio signal amplification module, and the fourth connector is also used to send the adjustment instruction generated by the sound box Bluetooth chip to the controller.
[0037] The audio signal amplification module is used to amplify the audio signal of the front-end power amplifier module and send to the controller.
[0038] The controller is used to receive the amplified audio signal, and call the preset lamp effect adjustment instruction based on the amplitude and frequency of the audio signal, and the controller is also used to receive the adjustment instruction and call the preset lamp effect adjustment instruction based on the adjustment instruction.
[0039] The controller sends a preset light effect adjustment instruction to the first light strip through the first connector or the second connector or the third connector; and the controller adjusts at least one of the color, the brightness, the flicker frequency and the light-on sequence of the first light strip through the preset light effect adjustment instruction.
[0040] Reference, such as Figure 2 With Figure 3 As shown in the figure, 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 triode Q401, a third resistor R407 and a fourth resistor R409; one end of the first capacitor C409 is connected with one end of the first resistor R404, the other end of the first resistor R404 is connected with 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 with the base of the triode Q401, the other end of the third resistor R406 is connected with the collector of the triode Q401, one end of the third resistor R406 is connected with the collector of the triode Q401, the other end of the third resistor R406 is connected with one end of the fourth resistor R409; the other end of the fourth resistor R409 is connected with the controller U403.
[0041] Among them, the other end of the first capacitor C409 is grounded, when the audio signal is input into the audio signal amplification module, the first capacitor C409 is used to filter out the noise in the audio signal, to avoid the noise interference affecting the performance of the amplifier.
[0042] The first resistor R404 can be an adjustable resistor or a fixed resistor.
[0043] In a 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.
[0044] In another possible implementation, the first resistor R404 can be an adjustable resistor, such asFigure 2 As shown, the resistor R404 is labeled as "470R / 5K1", which means that the resistance can be adjusted between 470 Ohms (Ω) and 5.1 kilo Ohms (kΩ), so as to adapt to different types of speakers.
[0045] 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.
[0046] Among them, as Figure 2 As shown, the model of the controller U403 is CA51F152S1. The 6th pin of the controller is connected with the fourth resistor.
[0047] For reference, as Figure 2 and Figure 4 As shown, the first connector CN404, the second connector CN405 and the third connector CN403 are connected with the 2nd pin, the 3rd pin and the 5th pin of the controller U403 respectively.
[0048] Among them, one of the first connector CN404, the second connector CN405 and the third connector CN403 is connected with the first lamp strip, and the other two connectors are reserved for connecting other lamp strips for subsequent expansion.
[0049] 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 wandering, etc.
[0050] For reference, as Figure 2 and Figure 4 As shown, the 1st pin and the 8th pin of the controller are connected with the programmable port CN406. This allows external devices (such as programmers or debugging tools) to program, update firmware or debug the controller. This makes the system flexible to update and modify the control logic to adapt to different application scenarios and needs.
[0051] For reference, the preset light effect adjustment instructions are as shown in the following table:
[0052]
[0053] For reference, as Figure 2 andFigure 5 As shown, the fourth connector CN402 is used to connect 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; and 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 an instruction to the third pin of the fourth connector CN402, and the controller changes the mode of the light strip by 1-10 modes.
[0054] In the embodiment, two modes of starting or changing the light and sound effect mode are provided. One mode is that the front-end power amplifier module generates an audio signal, and the audio signal is input to the audio signal amplification module. The first capacitor C409 filters out noise in the audio signal, and the triode Q401 amplifies the input audio signal. The amplified signal is transmitted to the controller U403, the controller U403 receives the amplified audio signal, and based on the amplitude and frequency of the signal, the preset light effect adjustment instruction is called to realize the adjustment of the light effect mode. The second mode is that the Bluetooth chip in the sound effect can directly send an instruction to the controller U403 through the third pin of the fourth connector. The instruction can be a specific light mode selection, brightness adjustment, color change, etc. The controller U403 receives the instruction from the Bluetooth chip through the third pin of the fourth connector. According to the instruction, the controller U403 will immediately change the mode of the light strip by 1-10 preset light effect modes.
[0055] The controller U403 sends the preset light effect adjustment instruction to the corresponding light strip through the first connector CN404, the second connector CN405 and the third connector CN403. The light strip adjusts the color, brightness, flashing frequency and light-on sequence according to the received instruction. For example, the user can send an instruction through a mobile phone or other Bluetooth device to select different light modes, such as rainbow right rotation, starlight, rainbow spectrum movement, etc.
[0056] The controller U403 sends the preset light effect adjustment instruction to the corresponding light strip through the first connector CN404, the second connector CN405 and the third connector CN403. The light strip adjusts the color, brightness, flashing frequency and light-on sequence according to the received instruction. For example, the user can send an instruction through a mobile phone or other Bluetooth device to select different light modes, such as rainbow right rotation, starlight, rainbow spectrum movement, etc.
[0057] In summary, in this embodiment, the audio signals output by the preamplifier module contain both frequency components and intensity information of the music. These signals are time-varying AC signals that reflect the rhythm, volume, and frequency characteristics of the music. The triode Q401 amplifies the input audio signals, making it easier for the controller U403 to detect changes in the signals. After receiving the amplified audio signals, the controller U403 analyzes the amplitude (i.e., volume) and frequency characteristics of the signals and, based on the amplitude and frequency of the signals, invokes the preset light effect adjustment instructions. For example, when the signal amplitude increases (indicating an increase in volume), the controller may increase the brightness 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 rapidly. In this way, the light effects change in synchronization with the rhythm and intensity of the music, enhancing the user's audio-visual experience. For example, during low-frequency beats, the lights can flash slowly; during high-frequency melodies, the lights can change color or brightness rapidly.
[0058] Users can also send instructions to the controller U403 through a mobile phone or other Bluetooth device through the fourth connector to select different light modes. These instructions can directly control the color, brightness, flashing frequency, etc. of the lights. There can be 1-10 different light effect modes preset to meet the needs of different users. For example, users can choose rainbow right rotation, starlight, rainbow spectrum movement, etc.
