步骤101、根据获取的输出电流与输出电压，确定出扬声器数量。
本申请实施例的各步骤可以由计算机设备执行。计算机设备包括但不限于智能电视、智能电视的外接设备或智能电视与外接设备等。
本申请实施例中，图2为本申请实施例提供的一种智能检测模块的示意图，如图2所示，图2所示的智能检测模块搭载于计算机设备，智能检测模块包括主芯片、音频功率放大模块、扬声器模块、检测电路与对比电路。其中主芯片与音频功率放大模块连接，音频功率放大模块与扬声器模块和检测电路连接，扬声器模块与检测电路连接，检测电路与对比电路连接，对比电路与音频功率放大模块连接。
音频功率放大模块的输出端向扬声器模块输送输出电流（Iout），向检测电路与扬声器模块输送输出电压（Vout），对比电路向音频功率放大模块发送反馈信号。计算机设备采集输出电流与输出电压；根据输出电流与输出电压，确定出扬声器的数量。
步骤102、根据扬声器数量，确定出系统通道。
本申请实施例中，系统通道包括2.0通道、2.1通道、4.0通道、4.1通道、5.1通道、5.1.2通道、7.1通道、7.1.4通道中至少一个。
步骤103、根据扬声器数量与系统通道，确定出目的音效参数。
本申请实施例中，图3为本申请实施例提供的一种匹配参数模块的示意图，如图3所示，图3示出的匹配参数模块搭载于计算机设备，匹配参数模块中预先存储了多个音效参数。计算机设备根据扬声器数量与系统通道，从多个音效参数中，确定出目的音效参数。
本申请实施例提供了一种声道的确定方法，根据获取的输出电流与输出电压，确定出扬声器数量；根据扬声器数量，确定出系统通道；根据扬声器数量与系统通道，确定出目的音效参数，由于高配、中配以及低配的计算机设备会分别对应不同的音效参数，从而在计算机设备确定出扬声器的数量之后，可根据扬声器的数量确定出计算机设备的音效参数，实现了计算机设备的高配、中配或低配的配置，使厂商无需多次研发扬声器系统，降低了厂商开发扬声器系统的设计成本，节省了人力资源与研发资源。
图4为本申请实施例提供的另一种声道的确定方法的流程图，如图4所示，该方法包括：
步骤201、根据采集的输出电流与输出电压，生成至少一个负载阻值。
本申请实施例中，如图2所示，主芯片的输出端将检测信号发送至音频功率放大模块。音频功率放大模块的输入端接收主芯片发送的检测信号，音频功率放大模块的输出端向扬声器模块和检测电路发送输出电压，向扬声器模块发送输出电流。扬声器模块的输入端接收音频功率放大模块发送的输出电流，扬声器模块的输出端将输出电流发送至检测电路，从而使环路中的检测电路可以自行识别到输出电流。检测电路将检测到的输出电流再发送至对比电路，对比电路中包括多个检测电路，每个检测电路均负责对输出电流进行校验，且均与扬声器模块中的扬声器进行连接，得到扬声器模块中每个扬声器的阻抗值。
步骤202、根据至少一个负载阻值，确定出扬声器数量。
本申请实施例中，计算机设备根据至少一个负载阻值与有效阈值范围，统计出至少一个在有效阈值范围内的负载阻值的有效数量；将有效数量作为扬声器数量。
如图2所示，对比电路将反馈信号发送至音频功率放大模块，反馈信号中包括至少一个负载阻值，音频功率放大模块筛选出在有效阈值范围内的至少一个负载阻值；音频功率放大模块向主芯片发送状态信号，状态信号中包括至少一个在有效阈值范围内的负载阻值，主芯片统计在有效阈值范围内的负载阻值的有效数量，将该有效数量作为扬声器数量。例如，由于扬声器的电阻值通常大于或等于2Ω且小于或等于32Ω，当负载阻值大于32Ω时，表明音频功率放大模块的输出端为开路；当负载阻值大于或等于2Ω且小于或等于32Ω时，表明扬声器模块中包括至少一个扬声器；当负载阻值小于2Ω时，表明扬声器模块处于短路状态。因此。有效阈值范围可以为负载阻值大于或等于2欧姆且小于或等于32欧姆的范围，当主芯片接收到的状态信号中包括4个大于或等于2欧姆且小于或等于32欧姆的负载阻值时，表明计算机设备中包括4个扬声器。
步骤203、根据扬声器数量与获取的第一通道，确定出系统通道。
本申请实施例中，第一通道为预先设置的扬声器的通道。确定出的系统通道为计算机设备可使用的通道。第一通道可包括2.0通道、2.1通道、4.0通道、4.1通道、5.1通道、5.1.2通道、7.1通道、7.1.4通道中至少一个。如图3所示，计算机设备中存储第一通道，计算机设备根据扬声器的数量，从第一通道中确定出系统通道。当计算机设备中仅包括2个扬声器时，系统通道为2.0通道；当计算机设备中包括4个扬声器时，系统通道可以为2.0通道与4.0通道。
步骤204、根据扬声器数量与系统通道，查找出至少一个音效参数。
本申请实施例中，目的音效参数包括音色均衡器参数、自动线性失真补偿参数、低音增强参数、立体声拓展参数、动态范围控制参数中至少一个。
计算机设备中存储了多个音效参数。每个音效参数都是根据不同扬声器数量与系统通道进行调试，保证了该扬声器数量与系统通道下，发挥扬声器最优的音质。计算机设备包括数字信号处理（Digital Signal Processing，DSP）芯片，工作人员可预先将扬声器数量、系统通道与目的音效参数的对应关系添加至DSP芯片中。计算机设备通过预先设置的数量通道与音效参数的对应关系，查找出至少一个音效参数。如图3所示，当扬声器数量的数量为4，系统通道为2.0通道与4.0通道时，查找出4个扬声器与2.0通道对应的音效参数，并查找出4个扬声器与4.0通道对应的音效参数。
步骤205、根据音效参数的优先级，从至少一个音效参数中确定出目的音效参数。
本申请实施例中，计算机设备中可预先存储音效参数的优先级。音效参数的优先级可根据输出的音质的高低来决定。例如，如图3所示，计算机设备查找出4个扬声器与2.0通道对应的音效参数，并查找出4个扬声器与4.0通道对应的音效参数。但计算机设备根据4个扬声器与4.0通道对应的音效参数输出的声音的音质高于计算机设备根据4个扬声器与2.0通道对应的音效参数输出的声音的音质，因此，4个扬声器与4.0通道对应的音效参数的优先级高于4个扬声器与2.0通道对应的音效参数的优先级，计算机设备确定出目的音效参数为4个扬声器与4.0通道对应的音效参数，
计算机设备根据确定出的目的音效参数播放声音，从而使计算机设备输出最优的音效，达到最优的音效效果。且当用户对声音的品质要求增加时，用户无需更换计算机设备或计算机设备的扬声器系统才可以达到对于音质的要求，可通过增加计算机设备的扬声器的数量的方式，使计算机设备确定出更优质的音效参数。
本申请实施例提供了一种声道的确定方法，根据获取的输出电流与输出电压，确定出扬声器数量；根据扬声器数量，确定出系统通道；根据扬声器数量与系统通道，确定出目的音效参数，从而通过配备不同的扬声器数量，实现了计算机设备的高配、中配或低配的配置，降低了厂商开发扬声器系统的设计成本，增加了声音播放的可拓展性，提升了产品的差异化，也无需为每个型号的计算机设备设置音效参数，节省了人力资源与研发资源，且为用户后期进行扬声器系统个性化升级增加了可能性与便利性，使用户可以在不更换计算机设备或扬声器系统时，也能满足对声音品质的追求。
