实施例一
图1是本公开实施例一提供的一种电子设备外接扬声器的切换方法的流程图，本实施例可适用于电子设备对所连接的外接扬声器判断是否进行切换的情况，该方法可以由电子设备外接扬声器的切换装置来执行，该装置可以由软件和/或硬件的方式实现。参见图1，本实施例提供的电子设备外接扬声器的切换方法具体包括如下步骤S110和S120：
在步骤S110中、检测所述电子设备是否连接有外接扬声器。
其中，所述电子设备可以是智能电视机、激光电视机或投影仪。外接扬声 器可以是以有线方式连接的扬声器，也可以是以无线方式连接的扬声器。该外接扬声器可以是原装扬声器，也可以是非原装扬声器。

其中，所述外接扬声器的性能参数与内部扬声器的性能参数的比较结果可以是：外接扬声器的性能优于内部扬声器的性能、内部扬声器的性能优于外接扬声器的性能或外接扬声器的性能与内部扬声器的性能相似。若比较结果是外接扬声器的性能优于内部扬声器的性能，则将电子设备切换至外接扬声器进行音频播放；若内部扬声器的性能优于外接扬声器的性能，或者是外接扬声器的性能与内部扬声器的性能相似，则继续使用内部扬声器进行音频播放。
具体的，所述性能参数可以包括频率响应范围、谐波失真、信噪比和声道数中的一种或多种。

实施例二

在步骤S210中、检测所述电子设备是否连接有外接扬声器。
在步骤S220中、若检测到所述电子设备连接有外接扬声器后，获取所述外接扬声器的标识。
其中，外接扬声器的标识可以包括外接扬声器的品牌和外接扬声器的型号。外接扬声器的品牌和型号可以通过射频识别技术或无线通信握手协议获取。
在步骤S230中、根据所述外接扬声器的标识从数据库中获取所述外接扬声器的性能参数。
其中，数据库中可以包括扬声器的标识和对应标识的扬声器的性能参数。根据所述外接扬声器的标识从数据库中获取所述外接扬声器的性能参数方式可以是，在数据库中查找与所述外接扬声器的标识匹配一致的扬声器，并从数据库中读取该匹配一致的扬声器的性能参数。
具体的，数据库可以包括本地数据库和/或云端数据库。其中，本地数据库可以设置在电子设备内部，也可以设置在与电子设备连接的存储介质中。云端数据库为设置在远程服务器中数据库。云端数据库中存储的扬声器的标识和扬声器的性能参数的数量大于本地数据库中存储的扬声器的标识和扬声器的性能参数的数量。根据所述外接扬声器的标识从数据库中获取所述外接扬声器的性能参数的方法可以是，从本地数据库查找与所述外接扬声器的标识匹配一致的扬声器，若查找到与所述外接扬声器的标识匹配一致的扬声器，则从本地数据库中获取该匹配一致的扬声器的性能参数；或者是，从远端数据库查找与所述外接扬声器的标识匹配一致的扬声器，若查找到与所述外接扬声器的标识匹配一致的扬声器，则从本地数据库中获取该匹配一致的扬声器的性能参数。
为方便外接扬声器性能参数的获取，可以在本地数据库中存储常用的扬声器的标识和对应标识的扬声器的性能参数。在云端数据库中存储，除本地数据库存储的扬声器的标识和对应标识的扬声器的性能参数之外的，扬声器的标识和对应标识的扬声器的性能参数。
可选地，为提高外接扬声器性能参数的获取速度，可选地，在本地数据库中查找与所述外接扬声器的标识匹配一致的扬声器，若查找到与所述外接扬声 器的标识匹配一致的扬声器，则从本地数据库中获取该匹配一致的扬声器的性能参数；若在本地数据库未查找到与所述外接扬声器的标识匹配一致的扬声器，则在云端数据库中查找与所述外接扬声器的标识匹配一致的扬声器；若在云端数据库中查找到与所述外接扬声器的标识匹配一致的扬声器，则从云端数据库中获取该匹配一致的扬声器的性能参数。
在步骤S240中、将所述外接扬声器的性能参数与内部扬声器的性能参数进行比较；
其中，内部扬声器的性能参数可以从本地数据库、云端数据库或其他存储介质中获取。所述外接扬声器的性能参数与内部扬声器的性能参数的比较可以是，当所述性能参数只有一种时，将外接扬声器的性能参数对应的数值与内部扬声器中相应的性能参数的数值进行比较，若外接扬声器的性能参数对应的数值大于或小于内部扬声器中相应的性能参数的数值，则判断所述外接扬声器的性能优于内部扬声器。例如，若外接扬声器的信噪比大于内部扬声器中相应的频率响应范围，则判断所述外接扬声器的性能优于内部扬声器；若外接扬声器的谐波失真小于内部扬声器中相应的性能参数的数值，则判断所述外接扬声器的性能优于内部扬声器。
当所述性能参数有多种时，可以根据预设性能参数比较标准进行判断。其中，预设性能参数比较标准可以是，若外接扬声器的多种性能参数中指定的一种或两种性能参数优于内部扬声器中相应的性能参数，则判断所述外接扬声器的性能优于内部扬声器。
例如，外接扬声器为5.1声道，则该外接扬声器包括6个声道，即包括一个中央声道、前置左声道、前置右声道、后置左声道、后置右声道和低音声道，声道数为6；内部扬声器为2.1声道，则该内部扬声器包括3个声道，即包括左声道、右声道，以及一个低音声道，声道数为3。预设性能参数比较标准是，若外接扬声器的声道数大于内部扬声器中的声道数，则判断所述外接扬声器的性能优于内部扬声器。因为，外接扬声器的声道数大于内部扬声器的声道数，所以根据预设性能参数比较标准可以判断所述外接扬声器的性能优于内部扬声器。
在步骤S250中、根据比较结果确定是否切换至外接扬声器进行音频播放。
本实施例技术方案，通过将所述外接扬声器的一种或多种性能参数与内部扬声器的一种或多种性能参数进行比较，根据比较结果确定是否切换至所述外 接扬声器，以解决电子设备所连接的外接扬声器的性能不如内部扬声器的性能好时盲目地进行切换的问题，提高电子设备的音频播放效果和用户体验。
