随着无线充电技术越来越普遍，越来越多的电子设备应用无线充电技术。例如，新能源汽车搭载无线快充模块，该无线充电模块可以给手机充电。该无线充电模块的最大功率可以达到40W。当无线充电模块以最大功率给手机充电时，手机发出大量的热量。此时，手机需要散热，通常是采用冷却风扇进行散热。但是，冷却风扇在散热时会产生较大的噪声，导致用户抱怨。为了防止冷却风扇在散热时会产生较大的噪声，通常是将冷却风扇进行优化，或者冷却风扇的安装路径进行优化。但是，冷却风扇在散热时依然会产生较大的噪声。

在本申请实施例中，以电子装置是无线充电装置为例进行说明。图2A示出了车辆的结构示意图。如图2A所示，新能源汽车1搭载无线充电装置11，该无线充电装置11用于为电子设备(如手机)进行无线充电。如图2A中所示的A区域中，手机2放在无线充电装置11上，在手机2与无线充电装置11的接触面上设有散热孔111。当无线充电装置11为手机2进行无线充电时，可以为手机2进行散热。具体的，如图2B所示，无线充电装置11包括无线充电模块113和风扇112。风扇112设置在散热孔111处，该风扇112可以为手机散热也可以为无线充电装置11散热。该无线充电模块的最大功率可以达到40W。
目前，由于该无线充电装置位于车辆内部的换挡杆前部，距离驾驶员及副驾驶人耳处距离较近，如，约50cm。当无线充电模块以最大功率给手机充电时，手机发出大量的热量。此时，手机需要散热，为满足散热要求风扇需要较大的转速进行散热。这样，风扇在散热时会产生较大的噪声，导致用户抱怨。
为了解决上述技术问题，本申请实施例提供一种风扇转速的调节方法，该方法应用于电子装置，该方法包括：当检测到车辆内的无线充电模块对电子设备进行无线充电时，电子装置获取车辆的第一车速、车辆内空调的第一档位。电子装置根据第一车速，第一档位，及预设的噪声等级对应关系信息，确定第一噪声等级。该噪声等级对应关系信息用于表征车速、档位和噪声等级的对应关系。电子装置根据第一噪声等级， 调节风扇的转速至第一转速，第一转速小于等于第一噪声等级对应的第二转速，风扇用于为电子设备散热。这样，只要根据噪声等级对应关系信息(或简称，噪声等级表)中的噪声等级来调节风扇的转速，均能掩盖风扇产生的噪声，避免了风扇散热时产生的噪声对用户的干扰。
其中，噪声等级表中的各噪声等级可以是车辆的车速和/或空调的档位对应的噪声等级，也可以是在风扇处于不同转速时产生的噪声被掩蔽时，空调的档位和/或车辆的车速对应的噪声等级。以下针对不同情况对本申请实施例提供一种风扇转速的调节方法进行详细说明：
第一种情况，噪声等级表中的各噪声等级是车辆的车速和/或空调的档位对应的噪声等级。也就是说，噪声等级表是基于车速和空调的档位确定的。
在第一种实施例中，电子设备根据车速和空调的档位产生的噪声，来调节风扇的转速。具体的，电子装置根据第一车速和第一档位，在噪声等级表中查询第一车速和/或第一档位对应的第一噪声等级。电子装置根据第一噪声等级，调节风扇的转速至第一转速。例如，假设：噪声等级表中记载“车速在30km/h＜V≤50km/h范围内，且未开空调，相应的，噪声等级为1级；车速在30km/h＜V≤50km/h范围内，且空调开在2档，相应的，噪声等级为3级”。当第一车速为40km/h，空调开在2档时，电子装置可以在噪声等级表中查找到第一车速和2挡对应的噪声等级为3级。那么，电子装置调节风扇的转速至3级噪声对应的转速。
在此情况下，电子装置根据第一噪声等级调节风扇的转速至第一转速，可以存在以下实现方式：
方式一、电子装置根据噪声等级调节无线充电模块的充电功率，再根据充电功率调节风扇的转速。具体的，电子装置根据第一噪声等级为无线充电模块配置第一充电功率。电子装置根据第一充电功率，及预设的充电功率与风扇转速的对应关系，调节至第一充电功率对应的第三转速。
示例性的，假设：无线充电模块的充电功率为40W。当无线充电模块采用40W的功率进行充电时，需要风扇以最大转速进行散热。当无线充电模块采用32W的功率进行充电时，需要风扇以最大转速*80％的转速进行散热。以此类推。假设，噪声等级与无线充电模块的充电功率的对应关系如下：噪声等级为3级，相应的，无线充电模块的充电功率为80％*40W；噪声等级为5级，相应的，无线充电模块的充电功率为100％*40W。如上，电子装置调节风扇的转速至3级噪声对应的转速。具体的，电子装置调节无线充电模块的充电功率为32W。假设充电功率与风扇的转速为线性关系，如AX＝BY，其中，A为无线充电模块的最大充电功率，B为风扇的最大转速，X、Y为占空比。例如，无线充电模块的充电功率为80％*40W，相应的，风扇的转速为80％*最大转速。这样，可以动态调整充电功率、风扇散热及噪声等级，可以实现在最大效率充电时，满足散热，且产生的噪声不会导致用户抱怨。
方式二、电子装置根据背景噪声(如车速和空调产生的噪声)与风扇产生的噪声，确定噪声等级，并调节风扇的转速。具体为，电子装置获取风扇的第四转速。电子装置根据第四转速，在预设的风扇转速表中查找第四转速对应的第二噪声等级。风扇转速表用于表征风扇转速与噪声等级的对应关系。当第二噪声等级大于第一噪声等级时， 电子装置将第四转速调至第一转速。
示例性的，假设，当前风扇的转速为最大转速，相应的，风扇的噪声的等级为5级；车速在30km/h＜V≤50km/h范围内，且空调开在2档，相应的，背景噪声等级为3级。在此情况下，电子装置可以确定风扇的噪声的等级大于背景噪声等级。这样，风扇产生的噪声会影响到用户。此时，电子装置将调节风扇的转速。具体的，电子装置将风扇的转速调节至背景噪声等级对应的转速，即电子装置将风扇的转速由最大转速调节至80％*最大转速。这样，背景噪声就掩蔽了风扇产生的噪声，避免了风扇散热时产生的噪声对用户的干扰。
第二种情况，在风扇处于不同转速时产生的噪声被掩蔽时，空调的档位和/或车辆的车速对应的噪声等级。也就是说，噪声等级表是基于风扇的转速、车辆的车速和空调的档位确定的。
具体的，电子装置获取在车辆内空调处于不同档位时人耳处的第一噪声频谱曲线。电子装置获取在车辆处于不同车速时人耳处的第二噪声频谱曲线。电子装置获取在风扇处于不同转速时人耳处的第三噪声频谱曲线。电子装置根据第一噪声频谱曲线、第二噪声频谱曲线、第三噪声频谱曲线和噪声掩蔽原理，确定在风扇处于不同转速时产生的噪声被掩蔽时空调的档位、车辆的车速。电子装置根据在风扇处于不同转速时产生的噪声被掩蔽时空调的档位、车辆的车速，确定噪声等级，并获得噪声等级表。
示例性的，电子装置可以根据第一噪声频谱曲线、第二噪声频谱曲线和第二噪声频谱曲线，确定各转速对应的噪声等级、各车速对应的噪声等级和各档位对应的各噪声的等级。电子装置根据噪声掩蔽原理，可以确定在一转速对应的噪声等级、一车速对应的噪声等级和一档位对应的噪声等级中取最大等级。例如，风扇在最大转速时对应5级噪声，车速在30km/h＜V≤50km/h范围内对应1级噪声，空调打开2档时对应3级噪声。这样，在风扇最大转速、车速30km/h＜V≤50km/h范围内，且空调打开2档时，噪声等级为5级。例如，风扇在最大转速时对应5级噪声，车速在30km/h＜V≤50km/h范围内对应1级噪声，空调打开3档以上时对应5级噪声。这样，在风扇最大转速、车速30km/h＜V≤50km/h范围内，且空调打开3档以上时，噪声等级为5级。再例如，风扇在50％*最大转速时对应0级噪声，车速在30km/h＜V≤50km/h范围内对应1级噪声，空调打开2档时对应3级噪声。这样，在风扇50％*最大转速、车速30km/h＜V≤50km/h范围内，且空调打开2档时，噪声等级为3级。以此类推。电子装置得到在风扇处于不同转速时产生的噪声被掩蔽时空调的档位、车辆的车速对应的噪声等级。例如，如上，车速30km/h＜V≤50km/h范围内，且空调打开3档以上时对应5级噪声；在车速30km/h＜V≤50km/h范围内，且空调打开2档时，噪声等级为3级。以此类推，得到噪声等级表。
在此情况下，电子装置可以根据第一车速和第一档位，在噪声等级表中查询第一噪声等级。电子装置根据第一噪声等级，调节风扇的转速至第一转速。这样，只要根据噪声等级表中的噪声等级来调节风扇的转速，均能掩盖风扇产生的噪声。因此，预先生成噪声等级表，再利用该噪声等级表来调整风扇的转速，可以有效提高风扇转速的调节效率。
以下对本申请实施例提供的一种风扇转速的调节方法进行详细介绍。
图3A-图3D为本申请实施例提供的一种风扇转速的调节方法的部分流程示意图。如图3A-图3D所示，以该方法的执行主体是电子装置为例进行说明的，该方法可以分以下阶段进行介绍，具体如下：
第一阶段，构建噪声等级表。如图3A所示：
S301、电子装置获取在车辆内空调处于不同档位时人耳处的第一噪声频谱曲线。
具体的，电子装置根据第一噪声频谱曲线，确定空调的各档位对应的噪声等级。
S302、电子装置获取在车辆处于不同车速时人耳处的第二噪声频谱曲线。
具体的，电子装置根据第二噪声频谱曲线，确定车辆的各车速对应的噪声等级。优选的，为了简化设计、提升使用体验，电子装置可以将车辆的车速按照第一梯度进行分档。其中，第一梯度可以理解为指定数值。例如，10km/h、5km/h、20km/h。
例如，以20km/h为例，电子装置可以将车辆的车速按照20km/h的梯度进行分档。得到车速档位可以如下：30km/h＜V≤50km/h、50km/h＜V≤70km/h、70km/h＜V≤90km/h。
S303、电子装置获取在风扇处于不同转速时人耳处的第三噪声频谱曲线。
具体的，电子装置根据第二噪声频谱曲线，确定风扇的各转速对应的噪声等级。
优选的，为了简化设计、提升使用体验，电子装置可以将风扇的转速按照第二梯度进行分档。其中，第二梯度可以理解为指定占空比。例如，10％、5％、20％。
例如，以10％为例，电子装置可以将风扇的转速按照10％的梯度进行分档。得到转速档位可以如下：0、10％、20％、30％、40％、50％、60％、70％、80％、90％、100％共计11个档位。
在实际应用中，综合考虑无线充电模块工作时，及电子设备(如手机)散热的情况，较低档位的风扇转速不被采用，例如，50％(不包括50％)以下的档位。
S304、电子装置根据第一噪声频谱曲线、第二噪声频谱曲线、第三噪声频谱曲线和噪声掩蔽原理，确定在风扇处于不同转速时产生的噪声被掩蔽时空调的档位、车辆的车速。
具体的，电子装置根据第一噪声频谱曲线、第二噪声频谱曲线、第三噪声频谱曲线，确定空调的各档位对应的噪声等级、车辆的各车速对应的噪声等级和风扇的各转速对应的噪声等级。之后，具体分如下情形进行说明：
情形一、电子装置根据噪声掩蔽原理，空调的档位和/或车辆的车速对应的噪声等级。示例的：
车辆的车速及其对应的噪声等级如下：V≤30km/h，相应的，噪声的等级为0；30km/h＜V≤50km/h，相应的，噪声的等级为1；50km/h＜V≤70km/h，相应的，噪声的等级为2；70km/h＜V≤90km/h，相应的，噪声的等级为3；90＜V≤100km/h，相应的，噪声的等级为4；＞100km/h，相应的，噪声的等级为5。
空调的档位及其对应的噪声等级如下：空调0档，相应的，噪声的等级为0；空调1档，相应的，噪声的等级为1；空调2档，相应的，噪声的等级为2；空调3档以上，相应的，噪声的等级为5。
根据噪声掩蔽原理，选取空调的档位和车辆的车速对应的最大噪声等级。例如，车速在30km/h＜V≤50km/h范围内，且未开空调，确定噪声等级为1；车速在30km/h ＜V≤50km/h范围内，且空调2档，确定噪声等级为3。以此类推。
情形二、电子装置根据噪声掩蔽原理，确定在风扇处于不同转速时产生的噪声被掩蔽时空调的档位、车辆的车速。
同情形一中所述的车辆的车速及其对应的噪声等级、空调的档位及其对应的噪声等级。再结合风扇的各转速对应的噪声等级。示例性的：
风扇的各转速对应的噪声等级如下：风扇转速占空比为50％，相应的，噪声的等级为0；风扇转速占空比为60％，相应的，噪声的等级为1；风扇转速占空比为70％，相应的，噪声的等级为2；风扇转速占空比为80％，相应的，噪声的等级为3；风扇转速占空比为90％，相应的，噪声的等级为4；风扇转速占空比为100％，相应的，噪声的等级为5。
根据噪声掩蔽原理，在风扇处于不同转速时产生的噪声被掩蔽时空调的档位、车辆的车速，例如：
例1、风扇转速占空比为100％对应5级噪声，车速在30km/h＜V≤50km/h范围内对应1级噪声，空调打开2档时对应3级噪声。这样，在风扇转速占空比为100％、车速30km/h＜V≤50km/h范围内，且空调打开2档时，噪声等级为5级。
例2、风扇占空比为100％对应5级噪声，车速在30km/h＜V≤50km/h范围内对应1级噪声，空调打开3档以上时对应5级噪声。这样，在风扇占空比为100％、车速30km/h＜V≤50km/h范围内，且空调打开3档以上时，噪声等级为5级。
例3、风扇占空比为70％对应2级噪声，车速在30km/h＜V≤50km/h范围内对应1级噪声，空调打开2档时对应3级噪声。这样，在风扇占空比为70％、车速30km/h＜V≤50km/h范围内，且空调打开2档时，噪声等级为3级。
可见，例2和例3中，风扇产生的噪声被掩蔽了，噪声等级由空调的档位和车辆的车速对应的最大噪声等级确定的。在此情况下，电子装置可以确定在风扇处于不同转速时产生的噪声被掩蔽时空调的档位、车辆的车速。之后，电子装置可以执行如下S305，具体的：
S305、电子装置根据在风扇处于不同转速时产生的噪声被掩蔽时空调的档位、车辆的车速，确定噪声等级，并获得噪声等级表(如上述噪声等级对应关系信息)。
在一种具体可实现方式中，预设条件可以包括通知，如图3B所示，S305包括：S3051、S3052、S3053和S3054。S3051、S3052、S3053和S3054具体可实现为：S3051、电子装置在在风扇处于不同转速时产生的噪声被掩蔽时，空调处于第二档位，车辆处于第二车速。S3052、电子装置确定第二档位对应第三噪声等级、第二车速对应第四噪声等级。S3053、当第三噪声等级大于等于第四噪声等级时，电子装置确定第二档位和第二车速对应第三噪声等级。S3054、当第三噪声等级小于第四噪声等级时，电子装置确定第二档位和第二车速对应第四噪声等级。
沿用上述示例性，在例2和例3中，风扇产生的噪声被掩蔽了，噪声等级由空调的档位和车辆的车速对应的最大噪声等级确定的。电装置可以得到表1所示的噪声等级表。如表1所示：
表1
车速\空调挡位 空调0档 空调1档 空调2档 空调3档及以上
V≤30km/h 0 2 3 5
30＜V≤50km/h 1 2 3 5
50＜V≤70km/h 2 2 3 5
70＜V≤90km/h 3 3 3 5
90＜V≤100km/h 4 4 4 5
＞100km/h 5 5 5 5
当然，该噪声等级表也可以根据其他情况进行调整，例如，车辆内增加了其他能够产生噪声的设备，噪声等级表可以结合其他设备产生的噪声进行调整。本申请实施例不做具体限定。
综上，可以得到在风扇处于不同转速时产生的噪声被背景噪声(或称车速和空调档位产生的噪声)掩蔽，该背景噪声等级如表2所示：
表2
背景噪声等级 0 1 2 3 4 5
风扇转速占空比 50％ 60％ 70％ 80％ 90％ 100％
第二阶段，使用噪声等级表。如图3C所示：
S306、当检测到车辆内的无线充电模块对电子设备进行无线充电时，电子装置获取车辆的第一车速、车辆内空调的第一档位。
示例性的，在无线充电模块对电子设备进行无线充电时，车辆上的距离传感器可以采集车辆的行驶距离，并将车辆的行驶距离发送电子装置，该电子装置接收到车辆的行驶距离，并根据行驶距离确定车辆的车速。
示例性的，在无线充电模块对电子设备进行无线充电时，车辆内的温度传感器可以检测车辆内的温度，并将车辆的行驶距离发送给电子装置，该电子装置接收到车辆的温度，并根据温度确定空调的档位。
S307、电子装置根据第一车速，第一档位，及预设的噪声等级表，确定第一噪声等级。
该噪声等级表用于表征车速、档位和噪声等级的对应关系。示例性的，该噪声等级表可以如上述表1所示。
S308、电子装置根据第一噪声等级，调节风扇的转速至第一转速，第一转速小于等于第一噪声等级对应的第二转速。
该风扇用于为电子设备散热。或者说，该风扇用于为采用无线充电模块进行充电的电子设备散热。
在电子装置确定第一噪声等级之后，电子装置可以根据第一噪声等级调节风扇的转速。例如，电子装置可以根据上述表2的对应关系，调节风扇的转速。
在一种具体可实现方式中，基于第一阶段中的情形二，如图3D所示，S308包括： S3081和S3082。S3081和S3082具体可实现为：
S3081、电子装置根据第一噪声等级，为无线充电模块配置第一充电功率。
电子装置存储有噪声等级与充电功率的对应关系。由于充电功率越大，需要风扇的转速越大。因此，噪声等级与充电功率的对应关系，可以等同于，噪声等级与风扇转速的对应关系。如上所述，充电功率与风扇的转速为线性关系。可以理解为，充电功率与风扇的转速同步调节。
例如，当电子装置确定第一噪声等级为3级，电子装置可以将无线充电模块的充电功率调整至噪声3级对应的功率。假设：无线充电模块的最大充电功率为40W。当第一噪声等级为3级，电子装置可以将充电功率调整至80％*40W。
S3082、电子装置根据第一充电功率，及预设的充电功率与风扇转速对应关系信息，调节至第一充电功率对应的第三转速，第三转速为第一转速。
其中，预设的充电功率与风扇转速对应关系信息用于表征充电功率与风扇转速的对应关系。
如上所述，充电功率与风扇的转速为线性关系。沿用上述示例，假设：无线充电模块的充电功率为40W。当无线充电模块采用32W的功率进行充电时，需要风扇以最大转速*80％的转速进行散热。
在另一种具体可实现方式中，基于第一阶段中的情形一，如图3D所示，S308包括：S3083、S3084和S3085。S3083、S3084和S3085具体可实现为：
S3083、电子装置获取风扇的第四转速。
具体的，风扇可以将转速发送给电子装置，电子装置接收风扇发送的转速。或者，电子装置的传感器可以采集风扇的转速信息。
S3084、电子装置根据第四转速，在预设的风扇转速表中查找第四转速对应的第二噪声等级。
其中，风扇转速表用于表征风扇转速与噪声等级的对应关系。示例性的，该风扇转速表可以如上述表1。
S3085、当第二噪声等级大于第一噪声等级时，电子装置将第四转速调至第一转速。
也就是说，根据噪声掩蔽原理，当风扇产生的噪声大于背景噪声(如车速和空调档位产生的噪声)时，电子装置将风扇的转速调低，以使风扇的转速产生的噪声小于等于背景噪声。
示例性的，当前风扇的转速为最大转速，相应的，风扇的噪声的等级为5级；车速在30km/h＜V≤50km/h范围内，且空调开在2档，相应的，背景噪声等级为3级。在此情况下，电子装置可以调整风扇的转速，使风扇的噪声的等级小于等于背景噪声等级。这样，风扇产生的噪声不会影响到用户。
