一种语音信号的输出方法和电子设备
本申请要求于2022年8月11日提交到国家知识产权局、申请号为202210960657.7、发明名称为“一种语音信号的输出方法和电子设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及终端技术领域，尤其涉及一种语音信号的输出方法和电子设备。
背景技术
目前，为了减少手持通话中声音的泄露，电子设备可以通过陶瓷驱动屏幕的发声组件发声。这样，用户手持通话的过程中，陶瓷驱动屏幕的发声组件中，屏幕发声区域可以正对用户的耳朵，电子设备发出的声音，可以大部分进入用户的耳中，只有极少一部分声音会泄露到周围环境中，所以，周围环境中的其他人，无法听清楚用户的通话内容，从而可以很好地保护用户的隐私。
但是，如果用户增大通话音量，进一步提高声音在人耳内的响度，就会增大陶瓷驱动屏幕的发声组件中陶瓷器件的驱动，这样的话，泄露到用户周围的声音强度也会增大，其他人便可以听清楚用户的通话内容，从而造成用户隐私的泄露，用户体验较差。
发明内容
本申请实施例提供了一种语音信号的输出方法和电子设备，以解决目前电子设备在手持通话的场景中，增大音量会造成用户通话内容的泄露，用户体验较差的问题。
第一方面，本申请实施例提供了一种语音信号的输出方法，该方法用于电子设备，所述电子设备包括第一发声组件和第二发声组件，所述第一发声组件设置于所述电子设备的第一位置，用户手持所述电子设备通话时，所述第一位置靠近所述用户的耳朵，所述第二发声组件设置于与所述第一位置不同的第二位置，所述方法包括：生成第一语音信号，所述第一语音信号是指根据下行语音信号生成的干扰信号；生成第二语音信号，所述第二语音信号是指对所述下行语音信号进行时延处理后，得到的与所述第一语音信号具有相同时延的语音信号；在相同的输出时间，分别通过所述第一发声组件输出所述第二语音信号，以及通过所述第二发声组件输出所述第一语音信号。
这样，可以通过根据下行语音信号生成的干扰信号，对下行语音信号进行掩蔽。在用户手持电子设备进行通话时，进入用户耳朵的声音强度足够大，可以保证用户可以清楚地听到通话内容。而对于周围环境中的其他人，由于干扰信号对下行语音信号的掩蔽作用，传到这些人耳朵的声音的强度较小，信息不完整，使得这些人无法听清楚用户的通话内容，从而很好地保护了用户的隐私，用户的体验更好。
在一种实现方式中，所述生成第一语音信号，包括：生成第一功率谱密度，所述第一功率谱密度是指根据所述下行语音信号计算得到的功率谱密度；根据所述第一功率谱密度生成所述第一语音信号。

这样，生成的第一语音信号，可以掩蔽掉下行语音信号中功率谱密度值较大的频点的信号，后续同时输出第一语音信号和第二语音信号之后，使得进入用户周围环境中其它人耳中的声音的强度减弱，从而无法听清楚用户的通话内容，可以很好地保护用户的隐私，用户的体验更好。

这样，当功率谱密度值大于第一平均功率的频点较为集中时，可以确定出较为准确的掩蔽信号，后续掩蔽效果较好。
在一种实现方式中，所述根据所述第一频点生成所述掩蔽信号，包括：如果所述第一频点的数量为多个，且所有所述第一频点中频率值最大的第一频点与频率值最小的第一频点之间，频率值相差大于等于第一预设频率阈值，则在所有所述第一频点中选出对应功率谱密度值最大的第一频点、频率值最大的第一频点和频率值最小的第一频点，确定为第四频点；在各所述第四频点附近，与各所述第四频点之间，频率值相差小于等于第二预设频率阈值处，分别选取一个频点，确定为第五频点；根据预设人耳掩蔽效应曲线，确定所述第五频点对应的幅值，所述幅值用于表征信号的强弱；根据所述第五频点的频率值和所述第五频点对应的幅值，生成所述掩蔽信号。
这样，当功率谱密度值大于第一平均功率的频点分布较为离散，且频率值最大的频点与频率值最小的频点之间频率值相差较大时，可以确定出较为准确的掩蔽信号，后续掩蔽效果较好。
在一种实现方式中，所述根据所述第一频点生成所述掩蔽信号，包括：如果所述第一频点的数量为多个，且所有所述第一频点中频率值最大的第一频点与频率值最小的第一频点之间，频率值相差大于等于第一预设频率阈值，则在各频点区间中，按照对应功率谱密度值由大至小的顺序，选出第二预设数量的第一频点，确定为第六频点，其中，各所述频 点区间的终止频点与起始频点之间，频率值相差小于等于第三预设频率阈值，且各所述频点区间包括的第一频点的数量大于等于第三预设数量；确定各所述频点区间对应的第七频点，所述第七频点位于相应频点区间中相邻两个所述第六频点之间；根据预设人耳掩蔽效应曲线，确定所述第七频点对应的幅值，所述幅值用于表征信号的强弱；根据所述第七频点的频率值和所述第七频点对应的幅值，生成所述掩蔽信号。
这样，当功率谱密度值大于第一平均功率的频点有两个或两个以上密集区间，且频率值最大的频点与频率值最小的频点之间频率值相差较大时，可以确定出较为准确的掩蔽信号，后续掩蔽效果较好。
在一种实现方式中，所述根据所述第一频点生成所述掩蔽信号，包括：如果所述第一频点的数量为一个，则在所述第一频点两侧分别选取一个频点，确定为第八频点；根据预设人耳掩蔽效应曲线，确定所述第八频点对应的幅值，所述幅值用于表征信号的强弱；根据所述第八频点的频率值和所述第八频点对应的幅值，生成所述掩蔽信号。
这样，当功率谱密度值大于第一平均功率的频点仅有一个时，可以确定出较为准确的掩蔽信号，后续掩蔽效果较好。

这样，当功率谱密度值大于第一平均功率的频点仅有一个时，可以确定出较为准确的掩蔽信号，后续掩蔽效果较好。
在一种实现方式中，所述根据所述第一功率谱密度生成粉噪信号，包括：确定第二平均功率，所述第二平均功率是指所有第十一频点的功率谱密度值的平均值，所述第十一频点是指所述第一功率谱密度对应的所有频点中，功率谱密度值小于等于第一平均功率的频点，所述第一平均功率是指所述第一功率谱密度对应的所有频点的功率谱密度值的平均值；获取所述第二平均功率对应的预设粉噪带通滤波增益；调整第一带通滤波器的增益为所述预设粉噪带通滤波增益；通过增益调整后的所述第一带通滤波器对粉噪信号源输出的信号进行带通滤波，生成所述粉噪信号。
这样，可以确定出可以与掩蔽信号相互配合的粉噪信号，使得后续生成的干扰信号能够更好地对下行语音信号进行掩蔽，从而较好地保护用户的通话隐私。
在一种实现方式中，所述根据所述第一功率谱密度生成所述第一语音信号，包括：根据所述第一功率谱密度，确定第一平均功率，所述第一平均功率是指所述第一功率谱密度对应的所有频点的功率谱密度值的平均值；确定第十二频点，所述第十二频点是指所述第一功率谱密度对应的所有频点中，对应功率谱密度值大于所述第一平均功率的频点；按照对应功率谱密度值由大至小的顺序，在所有所述第十二频点中选出第四预设数量的第十二频点，确定为第十三频点；根据所述第十三频点，生成陷波滤波器，所述陷波滤波器的陷波频率包括所述第十三频点的频率值；通过所述陷波滤波器对粉噪信号源输出的信号进行陷波滤波，生成所述第一语音信号。
这样，生成的第一语音信号，可以掩蔽掉下行语音信号中除功率谱密度值较大的频点 的信号之外的其余大部分信号，后续同时输出第一语音信号和第二语音信号之后，使得进入用户周围环境中其他人耳中的声音缺失大部分频点的信号的信息，从而无法听清楚用户的通话内容，同样可以很好地保护用户的隐私，用户的体验更好。

具体实施方式
下面结合附图，对本申请的技术方案进行描述。
在本申请的描述中，除非另有说明，“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。此外，“至少一个”是指一个或多个，“至少两个”是指两个或两个以上，“多个”也是指两个或两个以上。“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
需要说明的是，本申请中，“示例性地”或者“例如”等词用于表示作例子、例证或说明。本申请中被描述为“示例性地”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性地”或者“例如”等词旨在以具体方式呈现相关概念。
为了便于理解本申请的技术方案，下面先对本申请提供的技术方案的应用场景进行示例性说明。
目前，电子设备中可以设置多个发声组件，例如，通过陶瓷驱动屏幕的发声组件、顶部设置的扬声器和底部设置的扬声器等。在手持通话的场景中，电子设备通常通过陶瓷驱动屏幕的发声组件和/或顶部设置的扬声器，进行发声。这样的话，用户手持通话的过程中，陶瓷驱动屏幕的发声组件中，屏幕发声区域可以正对用户的耳朵，顶部扬声器也可以紧挨用户的耳朵，电子设备发出的大部分声音，可以进入用户的耳内，仅有极少部分的声音会泄露到周围环境中，周围环境中即使有其他人存在，也无法听清楚用户通话的内容，可以很好的保护用户的隐私。
但是，当用户调高通话的音量，进一步提升声音在耳内的响度时，陶瓷驱动会进一步增大，陶瓷驱动屏幕的发声组件发出的声音，以及顶部设置的扬声器发出的声音，强度也会增大，使得泄露到周围环境中的声音的强度也同步增大，这样的话，周围环境中的其他人，便可以听清楚用户的通话内容，从而导致用户通话内容的泄露，造成用户的隐私泄露，用户体验较差。
为了解决上述技术问题，本申请实施例提供了一种语音信号的输出方法、装置和电子设备。该方法可以应用于电子设备中，通过该方法，电子设备可以根据用户通话过程中的下行语音信号生成干扰信号，然后将下行语音信号和该干扰信号调整至相同的时延后，在相同的输出时间，分别通过电子设备中靠近人耳的第一发声组件输出下行语音信号，以及通过远离人耳的第二发声组件输出干扰信号，从而通过干扰信号对下行语音信号进行掩蔽，使得周围环境中的其他人无法听清楚用户的通话内容，达到保护用户通话隐私的目的，用户的体验更好。
需要说明的是，本申请的电子设备可以是静止的，也可以是移动的。电子设备可以包括通信终端、车载设备、移动设备、用户终端、移动终端、无线通信设备、便携式终端、用户代理、用户装置、服务设备或用户设备(user equipment，UE)等计算机网络中处于网络最外围的设备，主要用于数据的输入以及处理结果的输出或显示等。例如，终端设备可以是移动电话、无绳电话、智能手表、可穿戴设备、平板设备、具备无线通信功能的手持设备、计算设备、车载通信模块或连接到无线调制解调器的其它处理设备等。

例如，仍然如图8所示，第一频点的数量为三个，分别为f1、f2和f3，其中，频率值最大的第一频点f3的频率值为400HZ，频率值最小的第一频点f1的频率值为100HZ，两者相差的频率值为300HZ，小于1000HZ，则可以将第一频点f1、f2和f3，均确定为第二频点。
然后，如图9所示，可以在第二频点f1和第二频点f2中间选取一个频点fa1，还可以在第二频点f2和第二频点f3之间，选取一个频点fa2，然后，将频点fa1和频点fa2确定为第三频点。
之后，可以分别从预先保存的预设频率值中，找到与第三频点fa1的频率值和第三频点fa2的频率值相同的预设频率值，然后再分别找到对应的预设幅值，从而确定出第三频点fa1对应的幅值和第三频点fa2对应的幅值。进而确定出掩蔽信号。
示例性地，如果第一频点的数量为多个，且所有第一频点中频率值最大的第一频点与频率值最小的第一频点之间，频率值相差大于等于第一预设频率阈值，则在所有第一频点中选出对应功率谱密度值最大的第一频点、频率值最大的第一频点和频率值最小的第一频点，确定为第四频点。
然后，在各第四频点与其相邻第一频点之间，分别选取一个频点，确定为第五频点。或者，也可以在各个第四频点附近，与各所述第四频点之间，频率值相差小于等于第二预设频率阈值处，分别选取一个频点，确定为第五频点，即，各个第五频点与其相邻的第四频点之间，频率值相差小于等于第二预设频率阈值。其中，第二预设频率阈值可以根据实际应用场景的需求设置，例如，第二预设频率阈值可以设置为5Hz、20Hz或50Hz等。
之后，根据预设人耳掩蔽效应曲线，确定第五频点对应的幅值。幅值的具体内容可以 参考前述实施例的内容，此处不再赘述。最后，根据第五频点的频率值和第五频点对应的幅值，生成掩蔽信号。掩蔽信号包括频率为第五频点对应的频率值，且幅值为相应第五频点对应的幅值的信号。

然后，如图11所示，可以分别在第四频点f4、f5和f6附近，各选取一个频点fa3、fa4和fa5，然后，将频点fa3、fa4和fa5确定为第五频点。

然后，可以根据预设人耳掩蔽效应曲线，确定第八频点对应的幅值，幅值的内容可以参考前述实施例的内容，此处不再赘述。
之后，可以根据第八频点的频率值和第八频点对应的幅值，生成掩蔽信号。掩蔽信号包括频率值为第八频点的频率值，幅值为第八频点对应的幅值的信号。
例如，如图14所示，第一频点只有一个，为频点f17，则可以在第一频点f17两侧分别选取一个频点f18和f19，确定为第八频点。
然后，可以分别从预先存储的预设频率值中，找到与第八频点f18的频率值相同的预设频率值，以及与第八频点f19的频率值相同的预设频率值，然后再分别找到相应的预设幅值，从而确定出第八频点f18对应的幅值，以及第八频点f19对应的幅值。进而确定出掩蔽信号。
具体实现过程，还可以参考前述实施例的内容，此处不再赘述。
示例性地，如果第一频点的数量为一个，则可以在第一频点两侧分别选取一个频点，确定为第九频点。具体实现时，第九频点与第一频点之间，频率值可以相差第五预设频率阈值。其中，第五预设频率阈值可以根据实际应用场景的需求设置。例如，可以将第五预设频率阈值设置为5Hz、10Hz或20Hz等。

之后，可以根据预设人耳掩蔽效应曲线，确定第十频点对应的幅值，幅值的内容可以参考前述实施例的内容，此处不再赘述。最后，可以根据第十频点的频率值和第十频点对应的幅值，生成掩蔽信号。掩蔽信号包括频率为第十频点对应的频率值，且幅值为相应第十频点对应的幅值的信号。
例如，如图15所示，第一频点只有一个，为频点f20，则可以在第一频点f20两侧分别选取一个频点f21和f22，确定为第九频点。
然后，如图16所示，可以分别在第九频点f21与第一频点f20之间，以及第九频点f22与第一频点f20之间，各选取一个频点，分别为频点fa10和fa11，确定为第十频点。

具体实现过程，还可以参考前述实施例的内容，此处不再赘述。
如图17所示，根据第一功率谱密度生成粉噪信号，可以按照以下步骤实现：
步骤S501、确定第二平均功率。
其中，第二平均功率是指所有第十一频点的功率谱密度值的平均值。第十一频点是指第一功率谱密度对应的所有频点中，功率谱密度值小于等于第一平均功率的频点。第一平均功率是指第一功率谱密度对应的所有频点的功率谱密度值的平均值。
步骤S502、获取所述第二平均功率对应的预设粉噪带通滤波增益。
具体实现时，可以根据多次通话试验，在电子设备中预先设置一个增益规则表，增益规则表中对应存储有功率(后续称为预设功率)与粉噪带通滤波增益(后续称为预设粉噪带通滤波增益)。
在执行步骤S502时，电子设备可以从预先设置的增益规则表中，找出与第二平均功率相同的预设功率，然后，再从该增益规则表中，找出与该预设功率对应存储的预设粉噪带通滤波增益，将该预设粉噪带通滤波增益确定为第二平均功率对应的预设粉噪带通滤波增益。
步骤S503、调整第一带通滤波器的增益为所述预设粉噪带通滤波增益。
其中，第一带通滤波器预先设置于电子设备中，用于对粉噪信号源输出的信号进行带通滤波。
步骤S504、通过增益调整后的所述第一带通滤波器对粉噪信号源输出的信号进行带通滤波，生成粉噪信号。
需要说明的是，如果在步骤S201中，生成的第一功率谱密度为第一信号的功率谱密度，则在执行步骤S504时，还需要将第一带通滤波器的带宽设置为第一带宽，然后通过带宽为第一带宽，增益为第二平均功率对应的预设粉噪带通滤波增益的第一带通滤波器，对粉噪信号源输出的信号进行带通滤波，生成粉噪信号。
步骤S302、调整所述掩蔽信号和所述粉噪信号至相同时延。
生成掩蔽信号和粉噪信号之后，需要分别对掩蔽信号和粉噪信号进行时延调节，将掩蔽信号和粉噪信号调整至相同的时延。
步骤S303、根据调整至相同时延的所述掩蔽信号和所述粉噪信号，生成第一语音信号。
一种可能的实现方式中，将掩蔽信号和粉噪信号调整至相同时延之后，可以对调整至相同时延后的掩蔽信号和粉噪信号求和，然后将求和后得到的信号确定为第一语音信号。
一种可能的实现方式中，将掩蔽信号和粉噪信号调整至相同时延之后，还可以对调整至相同时延后的掩蔽信号和粉噪信号进行加权求和，然后将加权求和后得到的信号确定为第一语音信号。其中，掩蔽信号和粉噪信号分别对应的权重可以预先通过通话试验确定。
一种可能的实现方式中，将掩蔽信号和粉噪信号调整至相同的时延之后，还可以分别对时延调整后的掩蔽信号和粉噪信号进行增益调整，掩蔽信号对应的增益与粉噪信号对应的增益可以相同，也可以不同，均可以根据通话试验确定，然后预先设置于电子设备中，对掩蔽信号和粉噪信号进行增益调整时，从电子设备中调取即可。
然后，对增益调整后的掩蔽信号和粉噪信号进行求和或加权求和，将求和或加权求和 得到的信号确定为第一语音信号。这样，可以预先根据通话试验，更好地确定合适的掩蔽信号和粉噪信号，使得生成的第一语音信号后续可以更好的掩蔽下行语音信号，在保证用户听清楚通话内容的同时，避免周围环境中的其他人听清楚用户的通话内容，用户体验更好。
按照图6至图17所示的任意一种实施方式，生成的第一语音信号，可以掩蔽掉下行语音信号中功率谱密度值较大的频点的信号，后续同时输出第一语音信号和第二语音信号之后，使得进入用户周围环境中其它人耳中的声音的强度减弱，从而无法听清楚用户的通话内容，可以很好地保护用户的隐私，用户的体验更好。
示例性地，如图18所示，根据第一功率谱密度生成第一语音信号，还可以按照以下步骤实现：
步骤S601、根据第一功率谱密度，确定第一平均功率。
其中，第一平均功率是指第一功率谱密度对应的所有频点的功率谱密度值的平均值。
步骤S602、确定第十二频点。
其中，第十二频点是指第一功率谱密度对应的所有频点中，对应功率谱密度值大于第一平均功率的频点。
步骤S603、按照对应功率谱密度值由大至小的顺序，在所有所述第十二频点中选出第四预设数量的第十二频点，确定为第十三频点。
其中，第四预设数量可以根据实际应用场景的需求设置。例如，可以将第四预设数量设置为3个或5个。
步骤S604、根据所述第十三频点，生成陷波滤波器。
其中，陷波滤波器的陷波频率包括第十三频点的频率值。也就是说，通过该陷波滤波器滤波之后，可以滤掉频率为第十三频点的频率值的信号。
步骤S605、通过所述陷波滤波器对粉噪信号源输出的信号进行陷波滤波，生成第一语音信号。
需要说明的是，如果在步骤S201中，生成的第一功率谱密度为下行语音信号的功率谱密度，则在执行步骤S605时，通过陷波频率包括第十三频点的频率值的陷波滤波器，对粉噪信号源输出的信号进行陷波滤波，将陷波滤波后得到的信号确定为第一语音信号。
如果在步骤S201中，生成的第一功率谱密度为第一信号的功率谱密度，则在执行步骤S605时，还需要将陷波滤波器的带宽设置为第一带宽，然后通过带宽为第一带宽，陷波频率包括第十三频点的频率值的陷波滤波器，对粉噪信号源输出的信号进行陷波滤波，将陷波滤波后得到的信号确定为第一语音信号。
按照图18所示的实施方式，生成的第一语音信号，可以掩蔽掉下行语音信号中除功率谱密度值较大的频点的信号之外的其余大部分信号，后续同时输出第一语音信号和第二语音信号之后，使得进入用户周围环境中其它人耳中的声音缺失大部分频点的信号的信息，从而无法听清楚用户的通话内容，同样可以很好地保护用户的隐私，用户的体验更好。
在其它一些可选的实施例中，电子设备还可以在计算出第一功率谱密度之后，确定第一功率谱密度包含的所有功率谱密度值中，最大的功率谱密度值与第一平均功率之间的差值，是否大于等于预设功率谱密度阈值，如果最大的功率谱密度值与第一平均功率的差值大于等于预设功率谱密度阈值，则通过图18所示的实施方式，生成第一语音信号。或者， 如果最大的功率谱密度值与第一平均功率的差值小于预设功率谱密度阈值，则通过图6至图17所示的任意一种实施方式，生成第一语音信号。其中，预设功率谱密度阈值可以根据实际场景的需求设置。
这样的话，电子设备在实时且连续地获取到下行语音信号之后，可以实时地根据下行语音信号的属性，调整生成第一语音信号的实施方式，从而可以根据下行语音信号的属性，采用更加合适的方式，生成更加适合的干扰信号，在保证用户听清楚通话内容的同时，可以避免用户周围的其他人听清楚用户的通话内容，用户的体验更好。
在其它一些可选的实施例中，根据第一功率谱密度生成第一语音信号，还可以按照下述方式实现：电子设备还可以分别通过图18所示的实施方式，生成一个第一语音信号(在此实施例中，后续可以将该第一语音信号记为第四语音信号)，以及通过图6至图17所示的任意一种实施方式，生成一个第一语音信号(在此实施例中，后续可以将该第一语音信号记为第五语音信号)。然后，将第四语音信号与第五语音信号进行求和或加权求和，将求和或加权求和后得到的信号确定为干扰信号。之后，可以将该干扰信号确定为步骤S202中的第一语音信号。
需要说明的是，在其它一些可选的实施例中，在上述任意一个实施例的基础上，在根据下行语音信号生成第一语音信号之前，均可以先对下行语音信号的属性信息进行调整，例如，调整下行语音信号的信噪比和/或增益等属性信息，然后，根据属性信息调整后的下行语音信号生成第一语音信号，本申请对此不进行限制。
步骤S102、生成第二语音信号。
其中，第二语音信号是指对下行语音信号进行时延处理后，得到的与第一语音信号具有相同时延的语音信号。
需要说明的是，在一些可选的实施例中，在对下行语音信号进行时延处理之前，还可以先对下行语音信号的其它属性信息进行调整，例如，调整下行语音信号的信噪比和/或增益等属性信息。然后再对属性信息调整后的下行语音信号进行时延处理，得到与第一语音信号具有相同时延的语音信号，最后，将得到的语音信号确定为第二语音信号。
还需要说明的是，生成第一语音信号时，对下行语音信号的属性信息的调整方式，与生成第二语音信号时，对下行语音信号的属性信息的调整方式，可以相同，也可以不同，本申请对此不进行限制。
步骤S103、在相同的输出时间，分别通过第一发声组件输出所述第二语音信号，以及通过第二发声组件输出所述第一语音信号。
在相同的输出时间，通过第一发声组件输出第二语音信号，以及通过第二发声组件输出第一语音信号后，第一语音信号和第二语音信号均被转化为声音信号后发出。这样，第一语音信号可以对第二语音信号进行掩蔽，即，下行语音信号的干扰信号可以掩蔽下行语音信号。
其中，由于第一发声组件设置于电子设备的第一位置，在用户手持通话时，第一位置靠近用户的耳朵，甚至正对用户的耳朵，第二发声组件设置于远离用户耳朵的第二位置，这样，在用户调大音量的情况下，即使第一语音信号对第二语音信号进行了掩蔽，进入用户耳朵的声音的强度仍然足够大，用户可以清楚地听清楚通话的内容。而在用户周围的其它人，由于第一发声组件发出的声音和第二发声组件发出的声音都离耳朵较远，在第一语 音信号对第二语音信号进行掩蔽的情况下，进入耳朵的声音强度较小，无法听清楚用户的通话内容，从而达到保护用户通话隐私的目的，用户体验较好。
在一些可选的实施例中，电子设备中还可以设置第三发声组件，第三发声组件可以设置于靠近第一位置的第三位置，例如，第一发声组件可以为陶瓷驱动屏幕的发声组件，第二发声组件可以为设置于电子设备底部的扬声器，第三发声组件可以为设置于电子设备顶部的扬声器。此种应用场景下，本申请提供的语音信号的输出方法，还可以包括：生成第三语音信号，第三语音信号是指对下行语音信号进行时延处理后，得到的与第一语音信号具有相同时延的语音信号；在与第一语音信号和第二语音信号相同的输出时间，通过第三发声组件输出第三语音信号。这样，可以通过第三发声组件发出的声音对第一发声组件发出的声音进行补充，使得用户听到的声音更加清楚，提高用户的体验。
可见，本申请实施例提供的语音信号的输出方法中，可以通过根据下行语音信号生成的干扰信号，对下行语音信号进行掩蔽。在用户手持电子设备进行通话时，进入用户耳朵的声音强度足够大，可以保证用户可以清楚地听到通话内容。而对于周围环境中的其他人，由于干扰信号对下行语音信号的掩蔽作用，传到这些人耳朵的声音的强度较小，信息不完整，使得这些人无法听清楚用户的通话内容，从而很好地保护了用户的隐私，用户的体验更好。
本文中描述的各个方法实施例可以为独立的方案，也可以根据内在逻辑进行组合，这些方案都落入本申请的保护范围中。
