The left channel signal L and the right channel signal R are summed with signals, and then the obtained sound signal L+R is obtained. A low pass filter (LPF) is used to remove the high frequency band audio signal, so that the low frequency band sound signal of the sound signal L+R, that is, the 5.1 surround sound left surround channel signal is obtained, and the left surround sound is obtained. After the channel signal is digital-analog converted and power amplified, the fifth speaker 245, which is placed in the fifth sound hole 265, is retransmitted.
所述數位-類比轉換可以藉由數模轉換器加以實現，功率放大則可以採用功放電路加以實現，訊號相加可以藉由訊號相加器來加以實現。 The digital-to-analog conversion can be implemented by a digital-to-analog converter, and the power amplification can be implemented by using a power amplifier circuit, and the signal addition can be implemented by a signal adder.
