为了在小型化的电子设备中实现同步声音虚拟合成,建立一个基于对弦振动物理模型进行模态综合分析的数学模型并离散化,然后创建应用程序模拟某种声音,利用嵌入式并行数据处理板加速声音合成。用户只需输入击打信号,程序就能发出所模拟的声音,用户甚至可以对参数进行实时修改以便得到所需要的声音。该方法可以广泛应用在虚拟现实设备中,实现虚拟现实设备的小型化、便捷化。
In order to realize the synchronous synthesis of virtual sound in miniaturized electronic equipment, a mathematical model based on modal analysis of the string vibration physics model is established and discretized. Then an application program is created to simulate a certain sound. The embedded parallel data processing board Acceleration of sound synthesis. The user simply enters the hitting signal, the program can make the simulated sound, and the user can even modify the parameters in real time to get the desired sound. This method can be widely used in the virtual reality device to realize the miniaturization and convenience of the virtual reality device.
