本文通过对男性和女性声音的语音特征的研究,发现男女声的基音频率存在较大的差异,并设计了基于基音频率分析的男女声识别系统。男女声识别系统由以下三个模块电路构成:话筒放大器,低通滤波器,半波整流电路,单片机测量控制模块。话筒放大器采用NE5532P音前置芯片,对语音信号进行放大;八阶低通滤波器MAX293完成基音信号的提取;单片机STC12C5410AD实现频率测量和控制输出功能。经仿真与电路实测,男女声的识别效果良好。(In this paper, the voices of male and female voice characteristics of the findings of a study of the fundamental frequency of the sound of men and women there is a big difference, and the design of frequency analysis based on the pitch of the voice recognition system for men and women. Voice Recognition System for men and women from the circuit the following three modules: the microphone amplifier, low-pass filter, half-wave rectifier circuit, single-chip measurement control module. NE5532P sound using the microphone pre-amplifier chip amplification of voice signals eight MAX293-order low-pass filter to complete the extraction of pitch signal STC12C5410AD single-chip realization of the frequency of measurement and control output. By circuit simulation and measurement, the identification of male and female voices well.)

Android重力感应测试代码
Android 手机重力传感器调用+源码,作者:Himi,手机加速度传感器 ,也称为重力传感器,自SDK 1.5(api 3)就支持传感器了。解释:此传感器不仅对玩家反转手机的动作可以检测到,而且会根据反转手机的程度,得到传感器的值也会不同!sensor = sm.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);//得到一个重力传感器实例
//TYPE_ACCELEROMETER 加速度传感器(重力传感器)类型。
//TYPE_ALL 描述所有类型的传感器。
//TYPE_GYROSCOPE 陀螺仪传感器类型
//TYPE_LIGHT 光传感器类型
//TYPE_MAGNETIC_FIELD 恒定磁场传感器类型。
//TYPE_ORIENTATION 方向传感器类型。
//TYPE_PRESSURE 描述一个恒定的压力传感器类型
//TYPE_PROXIMITY 常量描述型接近传感器
//TYPE_TEMPERATURE 温度传感器类型描述
