[0031] A column speaker is a special type of audio equipment, known as a "sound column" for its slender, cylindrical design. It typically houses an amplifier board and speakers. When operating, the amplifier drives the speakers, providing more even sound coverage and improved sound propagation. It's particularly well-suited for use in large indoor or outdoor venues, such as conference rooms, churches, stadiums, and plazas.

[0032] In the related art, traditional column sound devices often require manual volume adjustment during use, which is cumbersome to operate and lacks intelligence, affecting the user experience.

[0033] In view of this, an embodiment of the present application provides a sound column device with intelligent volume adjustment, which can automatically adjust the output volume without manual operation, making the application more convenient and effectively improving the user experience.

[0034] Below, in conjunction with specific drawings, a sound column device for intelligently adjusting volume provided in an embodiment of the present application is described in detail.

[0035] The embodiment of the present application provides a sound column device for intelligently adjusting the volume, which can be applied to the technical field of audio equipment. Figure 1 , a sound column device for intelligently adjusting volume provided in an embodiment of the present application mainly includes:

[0036] a processor module, a first microphone, a second microphone, a power amplifier module, a camera, and a speaker;

[0037] The first microphone is used to collect ambient audio when the sound column device is not playing any sound, and the second microphone is used to collect target audio when the sound column device is playing any sound; the first microphone and the second microphone are both connected to the input end of the processor module;

[0038] The output end of the processor module is connected to the input end of the power amplifier module, and the output end of the power amplifier module is connected to the speaker;

[0039] The camera is used to collect image data around the sound column device, and the camera is connected to the input end of the processor module.

[0040] In an embodiment of the present application, a sound column device with intelligent volume adjustment is provided. The sound column device can automatically adjust the output volume without manual operation, which is more convenient to use and can effectively improve the user experience.

[0041] Specifically, in an embodiment of the present application, the sound column device for intelligent volume adjustment includes a processor module, a first microphone, a second microphone, a power amplifier module, a camera and a speaker, wherein the processor module is the core control module of the sound column device, which can be used to receive relevant detection signals, and control the signal output to the power amplifier module by calculation and processing, thereby achieving adjustment of the output volume. Specifically, the processor module may include a DSP chip, and the model of the DSP chip may be SSC3XXQE. The DSP chip has high-performance processing capabilities and supports multiple interfaces, such as serial interface, parallel interface, USB, Ethernet, etc., which is convenient for communication with other hardware. The DSP chip may include functions such as ADC (analog-to-digital converter), DAC (digital-to-analog converter), comparator and timer.

[0042] In this embodiment of the present application, a first microphone within the sound column device is used to collect ambient audio from the sound column device's external environment, i.e., the ambient noise level. The output of the first microphone is connected to the input of a processor module, and the collected ambient audio level can be converted into a related electrical signal (e.g., a voltage value). The analog value of the electrical signal is then converted into the ambient decibel value via an ADC interface within the processor module, thereby determining the volume of the ambient audio. Here, the first microphone can collect audio when the sound column device is not playing sound, thereby avoiding the influence of the sound column device's own sound. The second microphone can collect audio when the sound column device is playing sound, and the collected audio is recorded as the target audio. Similarly, the target audio can also be input into the input of the processor module. The processor module processes the target audio, filtering out the audio emitted by the sound column device itself, and the resulting audio is the ambient audio from the sound column device's external environment, i.e., the ambient noise level. The ambient audio level is determined by combining the results of the first and second microphones, thereby improving the accuracy of determining the volume of the ambient audio. For example, in the embodiment of the present application, the first microphone and the second microphone may be 9.7*6.7mm condenser electret microphone pickups with a sensitivity of -30dB.

[0043] In the embodiments of the present application, the sound column device also includes a camera that can collect image data of the area surrounding the sound column device. Based on this image data, the processor module can analyze and determine the number of people in the area. This can be achieved by including an image sensor chip within the processor module, such as the GC4653 image sensor chip. This chip can be configured with a computer vision algorithm to detect the number of people within the image. It should be noted that in the embodiments of the present application, only hardware with image analysis capabilities is used to detect the number of people, and no specific algorithmic changes are made.

[0044] In an embodiment of the present application, the processor module can analyze the volume of the ambient noise using the audio data collected by the two microphones. Furthermore, combined with the number of people determined by the surrounding image data, the processor module can determine the volume of the sound column device output. For example, the volume of the sound column device output can be positively correlated with the volume of the ambient noise and the number of people. The specific ratio can be set by relevant hardware parameters, which is not limited by the present application. The output of the processor module can be connected to the input of the power amplifier module. The power amplifier module can adjust the output power according to the control signal of the processor module, thereby driving the speaker to emit audio of the corresponding volume.

[0045] In some embodiments, the sound column device further includes a power module, and the power module is used to supply power to the processor module, the first microphone, the second microphone, the power amplifier module, the camera and the speaker.

[0046] In an embodiment of the present application, the sound column device may include a power module, which may include a battery. The battery may be a rechargeable battery, such as a solar cell. In this way, the smart volume control sound column device can be powered by solar energy in an outdoor environment, eliminating the need for frequent battery replacement or manual charging, thereby improving the ease of use of the smart volume control sound column device. In an embodiment of the present application, the output voltage of the power module may be 12V or other values, which is not limited by the present application.

[0047] In some embodiments, the column sound device further comprises a first audio amplification circuit and a second audio amplification circuit;

[0048] The first microphone is connected to the input end of the processor module through the first audio amplifier circuit, and the second microphone is connected to the input end of the processor module through the second audio amplifier circuit.

[0049] In an embodiment of the present application, a related audio amplifier circuit can be provided between the first microphone, the second microphone, and the processor module. The audio amplifier circuit corresponding to the first microphone is denoted as the first audio amplifier circuit, and the audio amplifier circuit corresponding to the second microphone is denoted as the second audio amplifier circuit. These circuits can amplify the collected signals to a certain extent, facilitating analysis by the processor module. Specifically, taking the first audio amplifier circuit as an example, it can include a MAX4467 chip and an SGM8904 operational amplifier chip. The MAX4467 chip can be used to preprocess the collected raw signals, and the SGM8904 operational amplifier chip can amplify and convert the preprocessed signals to obtain a corresponding voltage value, which is input into the ADC interface of the processor module.

[0050] The column sound device provided in the embodiments of this application can automatically adjust the volume based on the current ambient noise level. This effectively solves the problem of traditional column sound devices, where users cannot clearly hear the audio played when the ambient noise level is high or low. The column sound device is intelligent, automated, and user-friendly, meeting the market demand for high-quality, convenient, and personalized audio equipment, and can improve the user experience.
