目前,电子设备上的屏幕触控出声回路的延迟的测试,是通过额外一台手机对待测的设备进行高帧率拍摄,通过拍摄的视频拷贝到电脑,对图像轨道进行逐帧人工查阅,以屏幕某个区域颜色变化作为起始信号,视频中音轨的声音信号出现变化的时间点作为结束信号,计算此延迟。屏幕触控出声回路的延迟测试不完整,缺少屏幕从被点击到变色反应这段延迟,一般而言,这部分延迟在100ms左右,,难以保证拍摄测试动作的手机的图像和音轨是同步采集的,不同步会引入误差。使用不同的手机进行拍摄,得到延迟值也不一致,这个误差就是拍摄手机的图像和声音采集不同步导致的。需要人工逐帧看,效率低。At present, the delay test of the screen touch sound loop on the electronic device is to use an additional mobile phone to shoot the device under test at a high frame rate, copy the captured video to the computer, and manually check the image track frame by frame. The delay is calculated by taking the color change of a certain area of the screen as the start signal, and the time point when the sound signal of the audio track in the video changes as the end signal. The delay test of the screen touch sound loop is incomplete, lacking the delay from when the screen is clicked to the color change reaction. Generally speaking, this part of the delay is about 100ms, and it is difficult to ensure that the image and audio track of the mobile phone shooting the test action are synchronized Acquisition, out-of-sync will introduce errors. Different mobile phones are used to shoot, and the delay values obtained are not consistent. This error is caused by the out-of-synchronization of the image and sound collection of the mobile phone. It needs to be manually viewed frame by frame, which is inefficient.

具体实现中,当使用触控设备模拟用户触控屏幕时,由于触控设备集成了应变传感器(压力检测单元),应变变化时,电压信号同时会发生变化,当触控设备离开屏幕时,应变恢复,电压也会恢复到平稳状态,从而整个触控过程,触控设备会产生一段脉冲信号,其中上升沿对应起始接触屏幕的时刻T1(即第一时间),下降沿对应离开屏幕的时刻T2(即第三时间),脉冲信号的宽度对应触控设备施加压力与屏幕接触的时间。电子设备检测到触控屏的触控信号,通过一系列的内部信号处理,包括屏幕响应、网络响应、系统响应等,最终激励扬声器等器件发出声音信号,这个声音信号会被放置在器件附近的拾音设备采集到。拾音设备接收到声音信号的变化,会转换为电压信号的变化,此电压信号会被声卡采集。由于在发声环境下,接收到声音信号的拾音设备所生成的电压信号,比安静环境中所生成的电压信号会有明显变化,从而可以通过对电压波形设置阈值的方式,来检测器件发声时的时刻T3(即第二时间)。In the specific implementation, when the touch device is used to simulate the user's touch screen, because the touch device integrates a strain sensor (pressure detection unit), when the strain changes, the voltage signal will change at the same time. When the touch device leaves the screen, the strain After recovering, the voltage will also return to a stable state, so that during the entire touch process, the touch device will generate a pulse signal, in which the rising edge corresponds to the moment T1 when it first touches the screen (that is, the first time), and the falling edge corresponds to the moment when it leaves the screen T2 (that is, the third time), the width of the pulse signal corresponds to the time when the touch device applies pressure and touches the screen. The electronic device detects the touch signal of the touch screen, and through a series of internal signal processing, including screen response, network response, system response, etc., finally stimulates devices such as speakers to emit sound signals, and this sound signal will be placed near the device Acquired by sound pickup equipment. The change of the sound signal received by the pickup device will be converted into a change of the voltage signal, and the voltage signal will be collected by the sound card. In the sound environment, the voltage signal generated by the pickup device that receives the sound signal will change significantly compared with the voltage signal generated in the quiet environment, so it is possible to detect when the device is sounding by setting a threshold value for the voltage waveform. The moment T3 (ie the second time).
