具体实施方式
下面将参照附图更详细地描述本申请的示例性实施例。虽然附图中显示了本申请的示例性实施例，然而应当理解，可以以各种形式实现本申请而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本申请，并且能够将本申请的范围完整的传达给本领域的技术人员。
本申请在现有测试系统中的人工嘴基础上增设了用于模拟人脸部皮肤骨骼振动的振动激励器，通过一种振动激励器和人工嘴协同合作的方式实现对骨传导通话设备测试。
如图1所示，图1示出了根据本申请一个实施例的振动激励器设置位置示意图，在骨传导通话设备1所在的人工头部模型2的佩戴部位处，增设有与骨传导通话设备1相接触的振动激励器3，通过振动激励器3和人工嘴4协同合作的方式实现对骨传导通话设备1测试。振动激励器设置的位置主要取决于骨传导通话设备所在的位置，具体位置可以根据实际测试需求灵活设置，例如，如果骨传导通话设备佩戴在人耳位置，则将振动激励器也设置人耳位置附近并与骨传导通话设备相接触。如果骨传导通话设备根据产品形态不同，需要佩戴在人工头部模型的脸颊、颧骨或鼻梁等位置，则需要将振动激励器也设置在这些位置处，并保证振动激励器与骨传导通话设备相接触。
上述的人工头部模型是现有技术中的ACQUA测试系统中所经常采用的概念。本申请实施例中的人工头部模型具体可以包括脸颊、颧骨、鼻梁、嘴部、耳朵等多个部位，不局限于生理意义上的头部位置。本申请实施例的骨传导通话设备可以是带有麦克风和扬声器的 骨传导通话耳机，当然也可以是其他类型的骨传导通话设备，在此不作具体限定。
图2示出了根据本申请一个实施例的骨传导通话设备测试方法的流程示意图，参见图2，本申请实施例的骨传导通话设备测试方法具体包括如下步骤S210至步骤S240：
步骤S210，将测试音频分别传递至第一数字信号处理器和第二数字信号处理器进行处理。
在进行骨传导通话设备的测试时，需要先获取用于测试的音频，然后将测试音频传递至数字信号处理器(Digital Signal Process，简称DSP)进行处理。DSP是一种专门的微处理器，其处理目标通常是测量、过滤或压缩连续的真实模拟信号，大多数通用微处理器也能成功地执行数字信号处理算法，但是专用的DSP通常具有更好的功率效率，因此它们更适合于便携式设备，如移动电话和耳机等。现有的ACQUA测试系统中，DSP可以设置在一个独立的测量前端(MFE)内，其一端可以连接待测试的骨传导通话设备，另一端可以连接ACQUA测试系统中的主机设备(PC)，承担数据的采集、处理和传输等工作。本申请实施例也可以将两个数字信号处理器设置在上述独立的测量前端内，以进行实时的信号处理、过滤和均衡化等。
上述传递方式可以采用蓝牙传输的方式将测试音频分别传递至两个信号数字信号处理器，当然也可以采用其他的传输方式，在此不一一列举。这里设置两个数字信号处理器的目的是：由于本申请实施例中振动信号和声音信号的信号处理方式和传输效率等存在差异，通过采用两个数字信号处理器分别进行处理和传输控制，可以保证信号处理的准确性和处理效率。
步骤S220，将第一数字信号处理器处理后的音频信号传递至振动激励器，利用振动激励器模拟人发声时相应部位的骨骼振动产生振动信号。
步骤S230，将第二数字信号处理器处理后的音频信号传递至人工头部模型的人工嘴，利用人工嘴模拟人发声产生声音信号。
为了以作区分，这里将上述两个数字信号处理器分别称为第一数字信号处理器(DSP1)和第二数字信号处理器(DSP2)。其中DSP1主要用于对测试音频中与骨骼振动相关的音频信号进行处理，然后将处理好的音频信号传递至振动激励器，使振动激励器可以模拟人嘴部发声时相应部位的骨骼振动，进而产生振动信号。
DSP2主要用于对同一测试音频中与声音相关的音频信号进行处理，然后将处理好的音频信号传递至人工头部模型的人工嘴，通过人工嘴模拟人嘴部发声，进而产生声音信号。
步骤S240，利用骨传导通话设备拾取振动信号和声音信号，并根据骨传导通话设备 拾取的振动信号和声音信号对骨传导通话设备进行测试。
对振动激励器模拟人发声时相应部位的骨骼振动产生的振动信号以及人工嘴模拟人发声产生的声音信号，骨传导通话设备中设置的麦克风可以拾取到人工头部模型的人工嘴发声产生的声音信号，骨传导通话设备内的骨传导传感器可以拾取到人工头部模型上设置的振动激励器振动产生的振动信号。通过上述过程，可以完整的模拟人说话时骨骼的振动和人嘴的发声，为后续得到精准和客观的测试结果提供了基础。最后根据骨传导通话设备拾取到的声音信号及振动信号对骨传导通话设备进行测试，进而可以得到客观的测试结果，完成骨传导通话设备的客观评测。
在本申请的一个实施例中，第一数字信号处理器对测试音频进行的处理包括：获取与振动激励器佩戴部位对应的均衡器曲线；根据均衡器曲线对测试音频进行处理。
本申请实施例在利用第一数字信号处理器对测试音频进行处理时，可以先获取振动激励器所在的佩戴部位对应的均衡器曲线(Equalizer curve，简称Eq曲线)，均衡器曲线是一种可以分别调节各种频率成分电信号放大量的曲线，其功能就是提升一个特定频率或者衰减一个特定频率，在本申请实施例中主要用于使第一数字信号处理器按照该均衡器曲线对测试音频中与骨骼振动相关的信号进行信号频率等处理。
由于不同佩戴部位对应的均衡器曲线通常不同，因此在利用第一数字信号处理器对测试音频进行处理时，需要按需调用振动激励器佩戴部位所对应的均衡器曲线。例如，如果振动激励器设置在脸颊处，则调用脸颊部位对应的均衡器曲线。
在本申请的一个实施例中，获取与振动激励器佩戴部位对应的均衡器曲线包括：收集人发声时人体头部的不同佩戴部位振动的多个频响曲线；将各佩戴部位振动的多个频响曲线进行归一化处理，得到各佩戴部位各自对应的均衡器曲线并对这些均衡器曲线进行存储；根据振动激励器在人工头部模型的佩戴部位，查询得到与振动激励器佩戴部位对应的均衡器曲线。
本申请实施例在获取不同佩戴部位对应的均衡器曲线时，先收集了大量的人嘴部发声时，人体头部的不同佩戴部位振动的多个频响曲线。这里的频响曲线即频率响应(Frequency Response)曲线，可以简单理解为一个系统对不同频率的输入信号的响应。以骨传导通话耳机设备为例，“耳机频响”是通过电声测试仪内的信号发射器，输出稳定在0-20KHz的平稳信号，再通过接收麦克风来捕捉耳机发出的信号，最后以分贝dB的对数值的形式呈现出来，称之为“频响曲线”，其中频率(Frequency)为横坐标，响应(Relative Response[dB])为纵坐标。
通常情况下，骨传导通话设备在不同佩戴部位所对应的频响曲线是不同的，因此这里需要分别获取不同佩戴部位振动的多个频响曲线，然后将每个佩戴部位振动的多个频响曲线进行归一化拟合处理，得到每个佩戴部位各自对应的均衡器曲线，然后将这些均衡器曲线存储在第一数字信号处理器中，以便于后续按需调用。
在本申请的一个实施例中，第二数字信号处理器对测试音频进行的处理包括：对测试音频进行延时处理，以使同一时间上人工嘴发出的声音信号与振动激励器发出的振动信号同步到达骨传导通话设备。
如前所述，由于本申请对于振动信号的处理和对声音信号的处理是有差异的，因此采用了两个数字信号处理器分别进行处理和控制。本申请实施例中对于声音信号的处理过程相对较为简单，第二数字信号处理器处理后通过人工嘴可以直接将声音发出，而振动信号则需要在第一数字信号处理器中根据均衡器曲线进行一系列处理，处理后振动激励器需要模拟人说话时的骨骼振动来产生振动信号，因此本申请实施例中对于振动信号的处理过程相对复杂，耗时也相对较长，为了保证同一测试音源在经过上述处理后，能够使得人工嘴产生的声音信号与振动激励器产生的振动信号同时到达骨传导通话设备，保证信号传输的同步性，这里可以对第二数字信号处理器中接收到的测试音频进行一些延时处理等操作，进而保证后续骨传导通话设备拾取到的振动信号和声音信号的同步性和一致性，提高后续测试结果的准确性。
在本申请的一个实施例中，根据骨传导通话设备拾取的振动信号和声音信号对骨传导通话设备进行测试包括：将骨传导通话设备拾取的振动信号和声音信号进行合成处理，得到合成音频信号；将合成音频信号与标准音频信号进行比较，得到骨传导通话设备是否合格的测试结果。
本申请实施例在根据骨传导通话设备拾取的振动信号和声音信号对骨传导通话设备进行测试时，可以利用现有技术中的合成算法将骨传导通话设备拾取到的振动信号和声音信号进行合成处理，得到合成音频信号，然后将该合成音频信号与合格产品测得的标准音频信号进行比较，计算两者之间的偏差，如果偏差处于可接受的偏差范围内时，则可以认为骨传导通话设备的测试结果为测试合格，如果偏差没有处于可接受的偏差范围内时，则可以认为骨传导通话设备的测试结果为测试不合格。
当然除了上述测试方法，本领域技术人员也可以根据实际情况灵活选择其他的测试方法，例如可以将骨传导通话设备拾取到的振动信号直接与预设的标准振动信号进行比较，以及将骨传导通话设备拾取到的声音信号直接与预设的标准声音信号进行比较，进而得到 测试结果。
与前述骨传导通话设备测试方法同属于一个技术构思，本申请实施例还提供了骨传导通话设备测试装置。图3示出了本申请一个实施例的骨传导通话设备测试装置的功能框图，参见图3，在骨传导通话设备所在的人工头部模型的佩戴部位处，设置与骨传导通话设备相接触的振动激励器，该装置300包括：测试音频处理单元310、振动信号产生单元320、声音信号产生单元330和信号拾取及测试单元340。其中，

在本申请的一个实施例中，第二数字信号处理器对测试音频进行的处理包括：对测试音频进行延时处理，以使同一时间上人工嘴发出的声音信号与振动激励器发出的振动信号同步到达骨传导通话设备。
在本申请的一个实施例中，信号拾取及测试单元340具体用于：将骨传导通话设备拾取的振动信号和声音信号进行合成处理，得到合成音频信号；将合成音频信号与标准音频信号进行比较，得到骨传导通话设备是否合格的测试结果。
