【摘要】 现代声频工程中,在设备控制系统方面,实现友好的人机界面,是一项非常重要的实用指标。提出了在扩声系统中利用声波能实现随机人机互动控制功能的方法。借助于使用者在使用设备时发出的声波物理能,通过拾音器获取声波物理能,向机器内传送控制信息,当这一控制信息传到,且达到启动阈值的能量幅值要求时,通过智能识别和相关控制程序自动发出指令,完成对相关设备的操作控制,从而代替了手动的人工操作,实现了随机的人机互动控制功能。更多还原

【Abstract】 In the modern audio engineering, the realization of the friendly man-machine contact surface is an extremely important practical target in the device control system. The sound wave energy is used in the amplifying system, and the stochastic human-machine interaction control function is realized. The principle is that the sound wave physics energy is sent out to transmit the control information to the machine through the acoustic pickup when the equipment is used. When the control information is gained and the start catfish value satisfies the request of the energy peak-to-peak value, the instruction can be sent out automatically and the correlation equipment operation control is completed through the intelligent recognition and the correlation control procedure. Finally, the stochastic human-machine interaction control function is realized.更多还原
