[0002] FM stands for Frequency Modulation. FM radio function is the same as radio function, which receives broadcast signals transmitted by different power stations by adjusting different frequency bands.

[0027] This invention provides a method, apparatus, device, and storage medium for dynamically adjusting FM broadcasts.

[0028] Please see Figure 1 This is a flowchart illustrating the dynamic adjustment method for FM broadcasting provided in an embodiment of the present invention. This method is applied to an in-vehicle FM broadcasting device, which is connected to a broadcasting base station to receive broadcasts from the base station. The communication between the in-vehicle FM broadcasting device and the broadcasting base station is achieved through FM frequency modulation signals.

[0029] like Figure 1 As shown, the method includes the following steps S110 to S140.

[0030] S110. Obtain signal quality data from the radio station;

[0031] In this embodiment, the FM broadcast dynamic adjustment method is applied to in-vehicle FM broadcasting equipment and is applicable to any type of in-vehicle FM broadcasting equipment. Specifically, when the in-vehicle FM broadcasting equipment listens to a radio station from a base station, the signal received by the equipment is constantly changing due to factors such as the mobile environment and external signal interference, resulting in instability, high noise levels, and poor reception. Therefore, in order to receive high-quality radio signals, after the in-vehicle FM broadcasting equipment listens to a particular radio station, it periodically reads the signal quality data of that radio station program to monitor its signal quality. This signal quality data includes signal strength (level), bandwidth, and noise. The monitored signal quality data is then improved to ensure a better listening experience for the user.

[0032] In one embodiment, step S110 includes the following steps prior to:

[0033] Initialize FM parameter configuration.

[0034] In this embodiment, the FM parameter configuration is initialized. Before the user can implement the various functions of the in-vehicle FM broadcasting device, the various parameters of the device must first be initialized to ensure smooth operation. These FM parameters mainly include bandwidth, maximum soft mute value, soft mute slope, minimum and maximum high-cut values, and stereo mixing.

[0035] In one embodiment, prior to initializing the FM parameter configuration, the following steps are included:

[0036] Obtain and execute the boot command.

[0037] In this embodiment, before initializing the FM parameters in the in-vehicle FM radio device, the user needs to activate the device. Specifically, when the in-vehicle FM radio device receives the power-on command sent by the user, it responds to and executes the power-on command. The user can trigger the power-on command by pressing the power button, or by using wireless communication technology via a smart terminal, such as a Bluetooth smart switch, a Wi-Fi smart switch, or a custom gesture switch (e.g., "OK" for "on," "scissors" for "off"), or by starting the car and powering it on. The specific method for triggering the power-on command is not limited here.

[0038] S120. If it is determined that the signal strength in the signal quality data is greater than or equal to the first preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to the preset lower bandwidth limit and less than the preset upper bandwidth limit, then the bandwidth in the signal quality data is adjusted based on the first preset strategy, and the process of obtaining the signal quality data of the broadcasting station is returned.

[0039] In this embodiment, due to the instability of radio station signal quality, in order to improve the listening experience, the signal quality data of the received radio station is monitored in real time. The signal strength in the signal quality data is compared with a first preset signal strength threshold and a second preset signal strength threshold. The bandwidth in the signal quality data is also compared with a preset upper bandwidth limit and a preset lower bandwidth limit to determine whether the bandwidth parameter in the signal quality data needs adjustment. The first preset signal strength threshold is greater than the second preset signal strength threshold.

[0040] Specifically, if it is determined that the signal strength in the signal quality data is greater than or equal to the first preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to the preset lower bandwidth limit and less than the preset upper bandwidth limit, then the bandwidth parameter in the signal quality data is adjusted based on the first preset strategy to achieve a suitable bandwidth parameter. After adjusting the bandwidth parameter, the operation of obtaining the signal quality data of the radio station is returned, thereby improving the signal quality of the user during the listening process at regular intervals.

[0041] However, when the signal strength and bandwidth in the signal quality data do not meet the above conditions, that is, when it is determined that the signal strength in the signal quality data is greater than or equal to the first preset signal strength threshold, and the bandwidth in the signal quality data is less than the preset lower bandwidth limit or greater than or equal to the preset upper bandwidth limit, then there is no need to adjust the bandwidth parameter in the signal quality data, and the operation of obtaining the signal quality data of the broadcasting station is directly returned.

[0042] In one embodiment, step S120 includes:

[0043] The updated bandwidth is obtained by adding the bandwidth in the signal quality data to the first preset step value in the first preset strategy.

[0044] In this embodiment, the first preset strategy is used to increase the bandwidth in the signal quality data based on a first preset step size value. That is, when it is determined that the signal strength in the signal quality data is greater than or equal to a first preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to a preset lower bandwidth limit and less than a preset upper bandwidth limit, the bandwidth is adjusted by adding the bandwidth in the signal quality data to the first preset step size value, thereby achieving a suitable bandwidth parameter value and realizing dynamic adjustment of the bandwidth parameter value.

[0045] S130. If it is determined that the signal strength in the signal quality data is less than the first preset signal strength threshold and greater than the second preset signal strength threshold, and the bandwidth in the signal quality data is greater than the preset lower bandwidth limit and less than or equal to the preset upper bandwidth limit, then the bandwidth in the signal quality data is adjusted based on the second preset strategy, and the process of obtaining the signal quality data of the broadcasting station is returned.

[0046] In this embodiment, due to the instability of radio station signal quality, in order to improve the listening experience, the signal quality data of the received radio station is monitored in real time. The signal strength in the signal quality data is compared with a first preset signal strength threshold and a second preset signal strength threshold. The bandwidth in the signal quality data is also compared with a preset upper bandwidth limit and a preset lower bandwidth limit to determine whether the bandwidth parameter in the signal quality data needs adjustment. The first preset signal strength threshold is greater than the second preset signal strength threshold.

[0047] Specifically, when it is determined that the signal strength in the signal quality data is less than a first preset signal strength threshold and greater than a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, the bandwidth parameter in the signal quality data is adjusted based on the second preset strategy to achieve a suitable bandwidth parameter. After adjusting the bandwidth parameter, the operation of obtaining the signal quality data of the radio station is returned, thereby improving the signal quality of the user during the listening process at regular intervals.

[0048] However, when the signal strength and bandwidth in the signal quality data do not meet the above conditions, that is, when it is determined that the signal strength in the signal quality data is less than the first preset signal strength threshold and greater than the second preset signal strength threshold, and the bandwidth in the signal quality data is less than or equal to the preset lower bandwidth limit or greater than the preset upper bandwidth limit, then there is no need to adjust the bandwidth parameter in the signal quality data, and the operation of obtaining the signal quality data of the broadcasting station is directly returned.

[0049] In one embodiment, step S130 includes:

[0050] According to the second preset step size value in the second preset strategy, the bandwidth in the signal quality data is subtracted from the second preset step size value to obtain the updated bandwidth.

[0051] In this embodiment, the second preset strategy is used to reduce the bandwidth in the signal quality data based on a second preset step size value. That is, when it is determined that the signal strength in the signal quality data is less than a first preset signal strength threshold and greater than a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, the bandwidth is adjusted by subtracting the bandwidth in the signal quality data from the second preset step size value, thereby achieving a suitable bandwidth parameter value and realizing dynamic adjustment of the bandwidth parameter value.

[0052] S140. If it is determined that the signal strength in the signal quality data is less than or equal to the second preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to the preset lower bandwidth limit and less than or equal to the preset upper bandwidth limit, then the bandwidth and soft mute parameters in the signal quality data are adjusted based on the third preset strategy, and the process of obtaining the signal quality data of the radio station is returned.

[0053] In this embodiment, due to the instability of radio station signal quality, in order to improve the listening experience, the signal quality data of the received radio station is monitored in real time. The signal strength in the signal quality data is compared with a first preset signal strength threshold and a second preset signal strength threshold. The bandwidth in the signal quality data is also compared with a preset upper bandwidth limit and a preset lower bandwidth limit to determine whether the bandwidth parameter in the signal quality data needs adjustment. The first preset signal strength threshold is greater than the second preset signal strength threshold.

[0054] Specifically, when the signal strength in the signal quality data is determined to be less than or equal to a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, the bandwidth parameter and soft mute parameter in the signal quality data are adjusted based on a third preset strategy to achieve suitable bandwidth parameter values ​​and soft mute parameter values. After adjusting the bandwidth parameter and soft mute parameter, the process returns to retrieve the signal quality data of the broadcast station, thereby improving the signal quality for the user during listening in real time.

[0055] However, when the signal strength and bandwidth in the signal quality data do not meet the above conditions—that is, when the signal strength in the signal quality data is less than or equal to the second preset signal strength threshold, and the bandwidth in the signal quality data is less than the preset lower bandwidth limit or greater than the preset upper bandwidth limit—then there is no need to adjust the bandwidth parameter and soft mute parameter in the signal quality data, and the operation of obtaining the signal quality data of the broadcast station continues. Soft mute is used when there is a weak signal, poor signal-to-noise ratio, and high noise levels, affecting the listening experience. Soft mute automatically reduces the volume output; that is, it reduces noise by adjusting the soft mute parameter, thereby reducing user discomfort.

[0056] In one embodiment, step S140 includes:

[0057] Based on the third preset step value and the fourth preset step value in the third preset strategy, the bandwidth in the signal quality data is subtracted from the third preset step value to obtain the updated bandwidth, and the soft mute parameter is added to the fourth preset step value to obtain the updated soft mute parameter.

[0058] In this embodiment, the third preset strategy is used to reduce the bandwidth in the signal quality data based on a third preset step value, and to increase the soft mute parameter based on a fourth preset step value. Specifically, when the signal strength in the signal quality data is less than or equal to a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, the bandwidth is adjusted by subtracting the bandwidth in the signal quality data from the third preset step value, and the soft mute parameter is adjusted by adding the soft mute parameter to the fourth preset step value, thereby achieving suitable bandwidth and soft mute parameter values ​​and realizing dynamic adjustment of the bandwidth and soft mute parameter values.

[0059] In one embodiment, step S140 further includes:

[0060] If it is determined that the noise in the signal quality data is greater than a preset noise threshold, and the updated soft mute parameter is greater than or equal to the lower limit of the soft mute parameter and less than the upper limit of the soft mute parameter, then the updated soft mute parameter is increased based on the fourth preset strategy.

[0061] If it is determined that the noise in the signal quality data is less than a preset noise threshold, and the updated soft mute parameter is greater than the lower limit of the soft mute parameter but less than or equal to the upper limit of the soft mute parameter, then the updated soft mute parameter is reduced based on the fifth preset strategy.

[0062] In this embodiment, to ensure the user's listening experience, for cases with weak signal strength (i.e., when the signal strength in the quality data is less than or equal to a second preset signal strength threshold), the soft mute parameter is adjusted to obtain an updated soft mute parameter. Then, for cases where noise does not meet a preset noise threshold, this embodiment further adjusts the soft mute parameter. Specifically, when the noise in the signal quality data is greater than a preset noise threshold, and the updated soft mute parameter is greater than or equal to the lower limit of the soft mute parameter but less than the upper limit of the soft mute parameter, the updated soft mute parameter is further adjusted based on a fourth preset strategy to increase the updated soft mute parameter. The fourth preset strategy is used to adjust the updated soft mute parameter based on a fifth preset step size. The soft mute parameter is then increased. If the noise in the signal quality data is less than a preset noise threshold, and the updated soft mute parameter is greater than the lower limit of the soft mute parameter but less than or equal to the upper limit of the soft mute parameter, the updated soft mute parameter is adjusted again based on a fifth preset strategy to decrease it. The fifth preset strategy is used to decrease the updated soft mute parameter based on a sixth preset step size. If the noise in the signal quality data does not meet the above conditions, there is no need to adjust the updated soft mute parameter; the process can directly return to the operation of obtaining the signal quality data of the broadcast station, thereby achieving dynamic adjustment of the soft mute parameter and ensuring the signal quality of the received broadcast station.

[0063] This method enables dynamic adjustment and configuration of the signal quality data of the radio stations being listened to, in order to improve the signal quality under different environments, thereby enhancing the listening experience for users.

[0064] This invention also provides an FM broadcast dynamic adjustment device, which is used to perform any of the aforementioned FM broadcast dynamic adjustment methods.

[0065] Specifically, please refer to Figure 2 , Figure 2 This is a schematic block diagram of the FM broadcast dynamic adjustment device provided in an embodiment of the present invention.

[0066] like Figure 2 As shown, the FM broadcast dynamic adjustment device 100 includes: an acquisition unit 110, a first adjustment unit 120, a second adjustment unit 130, and a third adjustment unit 140.

[0067] Acquisition unit 110 is used to acquire signal quality data of the radio station;

[0068] In this embodiment, the FM radio dynamic adjustment device is configured in an in-vehicle FM radio device and is applicable to any type of in-vehicle FM radio device. Specifically, when the in-vehicle FM radio device listens to a radio station from a base station, the signal received by the device is constantly changing due to factors such as the mobile environment and external signal interference, resulting in instability, high noise levels, and poor reception. Therefore, in order to receive high-quality radio signals, after the in-vehicle FM radio device listens to a particular radio station, it periodically reads the signal quality data of that radio station program to monitor its signal quality. This signal quality data includes signal strength (level), bandwidth, and noise. The monitored signal quality data is then improved to ensure a better listening experience for the user.

[0069] In one embodiment, the acquisition unit 110 is preceded by:

[0070] Initialize FM parameter configuration.

[0071] In this embodiment, the FM parameter configuration is initialized. Before the user can implement the various functions of the in-vehicle FM broadcasting device, the various parameters of the device must first be initialized to ensure smooth operation. These FM parameters mainly include bandwidth, maximum soft mute value, soft mute slope, minimum and maximum high-cut values, and stereo mixing.

[0072] In one embodiment, prior to initializing the FM parameter configuration, the following steps are included:

[0073] Obtain and execute the boot command.

[0074] In this embodiment, before initializing the FM parameters in the in-vehicle FM radio device, the user needs to activate the device. Specifically, when the in-vehicle FM radio device receives the power-on command sent by the user, it responds to and executes the power-on command. The user can trigger the power-on command by pressing the power button, or by using wireless communication technology via a smart terminal, such as a Bluetooth smart switch, a Wi-Fi smart switch, or a custom gesture switch (e.g., "OK" for "on," "scissors" for "off"), or by starting the car and powering it on. The specific method for triggering the power-on command is not limited here.

[0075] The first adjustment unit 120 is configured to adjust the bandwidth in the signal quality data based on a first preset strategy if it is determined that the signal strength in the signal quality data is greater than or equal to a first preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to a preset lower bandwidth limit and less than a preset upper bandwidth limit, and then return to execute the acquisition of the signal quality data of the broadcasting station.

[0076] In this embodiment, due to the instability of radio station signal quality, in order to improve the listening experience, the signal quality data of the received radio station is monitored in real time. The signal strength in the signal quality data is compared with a first preset signal strength threshold and a second preset signal strength threshold. The bandwidth in the signal quality data is also compared with a preset upper bandwidth limit and a preset lower bandwidth limit to determine whether the bandwidth parameter in the signal quality data needs adjustment. The first preset signal strength threshold is greater than the second preset signal strength threshold.

[0077] Specifically, if it is determined that the signal strength in the signal quality data is greater than or equal to the first preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to the preset lower bandwidth limit and less than the preset upper bandwidth limit, then the bandwidth parameter in the signal quality data is adjusted based on the first preset strategy to achieve a suitable bandwidth parameter. After adjusting the bandwidth parameter, the operation of obtaining the signal quality data of the radio station is returned, thereby improving the signal quality of the user during the listening process at regular intervals.

[0078] However, when the signal strength and bandwidth in the signal quality data do not meet the above conditions, that is, when it is determined that the signal strength in the signal quality data is greater than or equal to the first preset signal strength threshold, and the bandwidth in the signal quality data is less than the preset lower bandwidth limit or greater than or equal to the preset upper bandwidth limit, then there is no need to adjust the bandwidth parameter in the signal quality data, and the operation of obtaining the signal quality data of the broadcasting station is directly returned.

[0079] In one embodiment, the first adjustment unit 120 includes:

[0080] The updated bandwidth is obtained by adding the bandwidth in the signal quality data to the first preset step value in the first preset strategy.

[0081] In this embodiment, the first preset strategy is used to increase the bandwidth in the signal quality data based on a first preset step size value. That is, when it is determined that the signal strength in the signal quality data is greater than or equal to a first preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to a preset lower bandwidth limit and less than a preset upper bandwidth limit, the bandwidth is adjusted by adding the bandwidth in the signal quality data to the first preset step size value, thereby achieving a suitable bandwidth parameter value and realizing dynamic adjustment of the bandwidth parameter value.

[0082] The second adjustment unit 130 is configured to adjust the bandwidth in the signal quality data based on a second preset strategy if it is determined that the signal strength in the signal quality data is less than a first preset signal strength threshold and greater than a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, and then return to execute the process of obtaining the signal quality data of the broadcasting station.

[0083] In this embodiment, due to the instability of radio station signal quality, in order to improve the listening experience, the signal quality data of the received radio station is monitored in real time. The signal strength in the signal quality data is compared with a first preset signal strength threshold and a second preset signal strength threshold. The bandwidth in the signal quality data is also compared with a preset upper bandwidth limit and a preset lower bandwidth limit to determine whether the bandwidth parameter in the signal quality data needs adjustment. The first preset signal strength threshold is greater than the second preset signal strength threshold.

[0084] Specifically, when it is determined that the signal strength in the signal quality data is less than a first preset signal strength threshold and greater than a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, the bandwidth parameter in the signal quality data is adjusted based on the second preset strategy to achieve a suitable bandwidth parameter. After adjusting the bandwidth parameter, the operation of obtaining the signal quality data of the radio station is returned, thereby improving the signal quality of the user during the listening process at regular intervals.

[0085] However, when the signal strength and bandwidth in the signal quality data do not meet the above conditions, that is, when it is determined that the signal strength in the signal quality data is less than the first preset signal strength threshold and greater than the second preset signal strength threshold, and the bandwidth in the signal quality data is less than or equal to the preset lower bandwidth limit or greater than the preset upper bandwidth limit, then there is no need to adjust the bandwidth parameter in the signal quality data, and the operation of obtaining the signal quality data of the broadcasting station is directly returned.

[0086] In one embodiment, the second adjustment unit 130 includes:

[0087] According to the second preset step size value in the second preset strategy, the bandwidth in the signal quality data is subtracted from the second preset step size value to obtain the updated bandwidth.

[0088] In this embodiment, the second preset strategy is used to reduce the bandwidth in the signal quality data based on a second preset step size value. That is, when it is determined that the signal strength in the signal quality data is less than a first preset signal strength threshold and greater than a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, the bandwidth is adjusted by subtracting the bandwidth in the signal quality data from the second preset step size value, thereby achieving a suitable bandwidth parameter value and realizing dynamic adjustment of the bandwidth parameter value.

[0089] The third adjustment unit 140 is used to adjust the bandwidth and soft mute parameters in the signal quality data based on a third preset strategy if it is determined that the signal strength in the signal quality data is less than or equal to a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, and then return to execute the acquisition of the signal quality data of the radio station.

[0090] In this embodiment, due to the instability of radio station signal quality, in order to improve the listening experience, the signal quality data of the received radio station is monitored in real time. The signal strength in the signal quality data is compared with a first preset signal strength threshold and a second preset signal strength threshold. The bandwidth in the signal quality data is also compared with a preset upper bandwidth limit and a preset lower bandwidth limit to determine whether the bandwidth parameter in the signal quality data needs adjustment. The first preset signal strength threshold is greater than the second preset signal strength threshold.

[0091] Specifically, when the signal strength in the signal quality data is determined to be less than or equal to a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, the bandwidth parameter and soft mute parameter in the signal quality data are adjusted based on a third preset strategy to achieve suitable bandwidth parameter values ​​and soft mute parameter values. After adjusting the bandwidth parameter and soft mute parameter, the process returns to retrieve the signal quality data of the broadcast station, thereby improving the signal quality for the user during listening in real time.

[0092] However, when the signal strength and bandwidth in the signal quality data do not meet the above conditions—that is, when the signal strength in the signal quality data is less than or equal to the second preset signal strength threshold, and the bandwidth in the signal quality data is less than the preset lower bandwidth limit or greater than the preset upper bandwidth limit—then there is no need to adjust the bandwidth parameter and soft mute parameter in the signal quality data, and the operation of obtaining the signal quality data of the broadcast station continues. Soft mute is used when there is a weak signal, poor signal-to-noise ratio, and high noise levels, affecting the listening experience. Soft mute automatically reduces the volume output; that is, it reduces noise by adjusting the soft mute parameter, thereby reducing user discomfort.

[0093] In one embodiment, the third adjustment unit 140 includes:

[0094] Based on the third preset step value and the fourth preset step value in the third preset strategy, the bandwidth in the signal quality data is subtracted from the third preset step value to obtain the updated bandwidth, and the soft mute parameter is added to the fourth preset step value to obtain the updated soft mute parameter.

[0095] In this embodiment, the third preset strategy is used to reduce the bandwidth in the signal quality data based on a third preset step value, and to increase the soft mute parameter based on a fourth preset step value. Specifically, when the signal strength in the signal quality data is less than or equal to a second preset signal strength threshold, and the bandwidth in the signal quality data is greater than or equal to a preset lower bandwidth limit and less than or equal to a preset upper bandwidth limit, the bandwidth is adjusted by subtracting the bandwidth in the signal quality data from the third preset step value, and the soft mute parameter is adjusted by adding the soft mute parameter to the fourth preset step value, thereby achieving suitable bandwidth and soft mute parameter values ​​and realizing dynamic adjustment of the bandwidth and soft mute parameter values.

[0096] In one embodiment, the third adjustment unit 140 further includes:

[0097] If it is determined that the noise in the signal quality data is greater than a preset noise threshold, and the updated soft mute parameter is greater than or equal to the lower limit of the soft mute parameter and less than the upper limit of the soft mute parameter, then the updated soft mute parameter is increased based on the fourth preset strategy.

[0098] If it is determined that the noise in the signal quality data is less than a preset noise threshold, and the updated soft mute parameter is greater than the lower limit of the soft mute parameter but less than or equal to the upper limit of the soft mute parameter, then the updated soft mute parameter is reduced based on the fifth preset strategy.

[0099] In this embodiment, to ensure the user's listening experience, for cases with weak signal strength (i.e., when the signal strength in the quality data is less than or equal to a second preset signal strength threshold), the soft mute parameter is adjusted to obtain an updated soft mute parameter. Then, for cases where noise does not meet a preset noise threshold, this embodiment further adjusts the soft mute parameter. Specifically, when the noise in the signal quality data is greater than a preset noise threshold, and the updated soft mute parameter is greater than or equal to the lower limit of the soft mute parameter but less than the upper limit of the soft mute parameter, the updated soft mute parameter is further adjusted based on a fourth preset strategy to increase the updated soft mute parameter. The fourth preset strategy is used to adjust the updated soft mute parameter based on a fifth preset step size. The soft mute parameter is then increased. If the noise in the signal quality data is less than a preset noise threshold, and the updated soft mute parameter is greater than the lower limit of the soft mute parameter but less than or equal to the upper limit of the soft mute parameter, the updated soft mute parameter is adjusted again based on a fifth preset strategy to decrease it. The fifth preset strategy is used to decrease the updated soft mute parameter based on a sixth preset step size. If the noise in the signal quality data does not meet the above conditions, there is no need to adjust the updated soft mute parameter; the process can directly return to the operation of obtaining the signal quality data of the broadcast station, thereby achieving dynamic adjustment of the soft mute parameter and ensuring the signal quality of the received broadcast station.

[0100] This device enables dynamic adjustment and configuration of the signal quality data of the radio stations being listened to, in order to improve the signal quality in different environments and thus enhance the listening experience for users.
