Brazier sound system

The utility model discloses a brazier sound system, which is used for sampling left and right sound channel signals and a bass signal, and filtering and weighting the left and right sound channel signals and the bass signal to obtain a first filtering signal and a second filtering signal, and the controller is used for receiving the first filtering signal and the second filtering signal, superposing the first filtering signal and the second filtering signal, performing smooth filtering to obtain a first numerical value, when the first numerical value continuously reaches a rhythm point threshold for multiple times, considering that the rhythm point is a music rhythm point, and then controlling the electromagnetic valve to act through the PWM module so as to control the flame to rhythm according to the music rhythm. According to the invention, the flame rhythm does not lag behind the music beats. 本发明公开了一种火盆音响系统，其将左右声道信号和低音信号进行采样，并将左右声道信号和低音信号进行过滤、加权处理以得到第一滤波信号和第二滤波信号，并将第一滤波信号和第二滤波信号进行叠加并进行平滑滤波以得到第一数值，在第一数值连续多次
