[0002] In the process of using traditional radios, users often need to manually adjust the volume to adapt to different environmental noise levels, which is not only cumbersome to operate, but also difficult to achieve the best listening effect.

These advantages together make the system perform well in providing personalized and convenient listening experience.

[0076] Embodiment 2

[0077] When the environment perception module in the first embodiment is working, the following steps are included:

[0078] Data collection: The microphone, color temperature detection device and CMOS sensor work simultaneously to collect environmental noise, color temperature information and real-time environmental images respectively. The environmental noise is used to determine the noise level of the environment where the radio is located, so as to perform adaptive volume control according to the noise level of the environment where the radio is located, such as increasing the volume in a noisy environment and reducing the volume in a quiet environment. The color temperature information is used to determine whether the radio is in an indoor environment or an outdoor environment, so as to control the radio to output a larger volume in an outdoor environment. The environmental image is used to determine the number of people near the radio, so as to control the increase of the radio volume according to the increase in the number of people.

[0079] Data preprocessing: the collected data is transmitted to a dedicated signal processing chip for preprocessing. The noise signal collected by the microphone is filtered, amplified, and converted into a digital signal that can be used to judge the noise level, thereby converting the collected data into analyzable digital signals and data to obtain standardized data.

[0080] Data transmission, the standardized data is transmitted to the core processing module, waiting for further analysis by the core processing module.

[0081] By integrating microphones, color temperature detection equipment and CMOS sensors, the synchronous collection of environmental noise, color temperature and real-time images is achieved. The radio volume can be intelligently and dynamically adjusted according to the environmental noise level, indoor and outdoor environment and the number of people, which improves the user experience. At the same time, the data conversion in the preprocessing stage ensures that the core processing module can analyze data efficiently and accurately, which improves the overall intelligence and automation level of the system.

[0082] Embodiment 3

[0083] The core processing module in the first embodiment includes the following steps when receiving and processing the environmental condition parameters collected by the environmental perception module and executing the adaptive volume adjustment algorithm according to the processing results:

[0084] Data reception,The core processing module first receives data from various sensors;

[0085] Data preprocessing: further preprocessing the received raw data to improve the accuracy and reliability of the data;

[0086] Data analysis and fusion: Process the noise signals collected by the microphone to calculate the ambient noise level, and analyze the data collected by the color temperature detection device to determine whether the radio is in an indoor or outdoor environment; determine the number of people around: estimate the number of people in the room and their activity status by processing and analyzing the data of the CMOS sensor;

[0087] Adaptive volume adjustment algorithm execution, based on the analyzed and fused data, the core processing module executes the adaptive volume adjustment algorithm, first distinguishes between indoor and outdoor environments, sets different volume benchmarks for different environments, then considers the impact of the number of people and activity status on the volume, and corrects the volume benchmark. Based on the set volume benchmark, the volume is dynamically adjusted according to the ambient noise level. Finally, the core processing module outputs the corresponding control signal to adjust the volume of the radio.

[0088] The following formula is used to express the strength of the noise signal:

[0089] P noise =V noise 2 / R;

[0090] Among them, P noise Represents the power of the noise signal, V noise represents the voltage amplitude of the noise signal, and R represents the impedance of the microphone.

[0091] The core processing module receives and processes data from microphones, color temperature detection devices and CMOS sensors to accurately analyze and integrate environmental noise levels, indoor and outdoor environments, and the number of people near the radio, and then executes an adaptive volume adjustment algorithm. It can intelligently set and adjust the radio volume according to different environmental conditions, significantly improving the accuracy and intelligence of volume adjustment, and providing users with a more comfortable and personalized listening experience.

[0092] Embodiment 4

[0093] When the core processing module in the third embodiment determines that the radio is in an indoor environment, it first selects an indoor volume benchmark, and then adjusts the volume benchmark according to the number of people. For example, when the number of people is 1, the volume benchmark remains unchanged. When the number of people increases by 1, the volume benchmark increases by a fixed percentage, and the fixed percentage of increase can be personalized by the user through the buttons in the user interface module, such as 5% of the initial value and 10% of the maximum value, until the increase upper limit of 60% of the volume benchmark is reached. Then, the volume benchmark is corrected according to the activity status of the people. When the people are in a stationary state, the volume benchmark remains unchanged. When it is detected that there are people in an active state, the volume benchmark is increased according to the number of active people. Among them, when there is one active person, it is increased by 9% again on the basis of the above volume benchmark. When there are two active people, it is increased by 15% again on the basis of the above volume benchmark. This value is set by the factory until the increase upper limit of 200% of the volume benchmark is reached. Finally, the volume is dynamically adjusted according to the environmental noise level. When the noise is large, the volume is increased, and when the noise is small, the volume is reduced.

[0094] Among them, the principle formula of the adaptive volume adjustment algorithm is:

[0095] V output =V input *G(P noise ,P ambient ,N)

[0096] Among them, V output Indicates the output volume, V input represents the input volume (i.e., the volume of the original audio signal received by the radio), G represents the gain function, which is based on the ambient noise level P noise , ambient light P ambient and the number of personnel N to calculate the required gain.

[0097] When the core processing module determines that the radio is in an indoor environment, it flexibly applies the indoor volume benchmark and makes intelligent adjustments based on the number of people and their activity status. Users can personalize a fixed percentage of volume increase. At the same time, the system has an upper limit on the increase of the volume benchmark to ensure that the volume adjustment meets user needs while avoiding excessive interference. Finally, it makes dynamic adjustments based on the ambient noise level, achieving highly intelligent, personalized and comfortable adjustment of the radio volume in indoor environments, significantly improving the user experience.

[0098] Embodiment 5

[0099] When the core processing module in the above-mentioned third embodiment determines that the radio is in an outdoor environment, it no longer determines the number of people and the activity status of the people, but directly selects a fixed outdoor volume benchmark, and the selected outdoor volume benchmark is greater than the indoor volume benchmark to adapt to the noisy outdoor environment, and then dynamically adjusts the volume according to the ambient noise level, increasing the volume when the noise is louder and reducing the volume when the noise is smaller.

[0100] When the radio is in an outdoor environment, the core processing module directly adopts a fixed outdoor volume benchmark that is higher than the indoor volume benchmark to adapt to the noisier outdoor environment, and on this basis makes dynamic adjustments according to the ambient noise level. This not only simplifies the processing process, but also ensures that the volume of the radio in the outdoor environment can be clearly conveyed, effectively improving the user's listening experience when using the radio outdoors.

[0101] Embodiment 6

[0102] The user interface module in the above embodiment 1 includes the following functions:

[0103] The radio's power on / off, volume adjustment, working mode and channel selection functions are realized through buttons, thereby realizing the normal use of the radio; the radio's status information, channel information and volume information are displayed on the display screen, so that users can check the working status and the status of the radio conveniently; the volume benchmark of the core processing module in executing the adaptive volume adjustment algorithm is adjusted in a personalized manner through buttons, such as increasing the volume benchmark, reducing the personalized setting of the volume benchmark, and manually adjusting the volume under the current adaptive volume adjustment state; the adaptive volume adjustment function of the core processing module is controlled to be turned on and off through buttons, such as controlling the adaptive volume adjustment function to be turned off in an outdoor environment to ensure the user's listening experience, and controlling the adaptive volume adjustment function to be turned off in a resting state, and manually reducing the volume to ensure the user's resting experience.

[0104] The user interface module enables comprehensive control and status display of the radio, which not only facilitates users to perform basic operations such as switching on and off, adjusting volume, working mode and channel selection, but also allows users to view the radio status in real time through the display screen. More importantly, users can personalize the volume baseline and manually adjust the volume, and flexibly control the switch of the adaptive volume adjustment function, thereby ensuring the best listening and rest experience in different scenarios, significantly improving the radio's ease of use and user satisfaction.

[0105] Embodiment 7

[0106] See also Figure 2 , an adaptive volume adjustment method, comprising the following steps:

[0107] Use the radio adaptive volume adjustment platform to determine whether the current environment is indoor or outdoor;

[0108] When it is determined to be an indoor environment, the CMOS sensor is activated to sense the environment where the radio is located, so as to obtain and output a real-time environment image;

[0109] The core processing module processes and analyzes the real-time environmental image to obtain the number of people and their activity status in the environment where the radio is located;
