Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0021] Such as figure 1 As shown, the high-power power amplifier circuit based on Class D amplification to promote Class B output includes a power amplifier circuit 1 and a Class D amplifier driving circuit. In the present invention, the power amplifier circuit 1 is connected with a positive Class D amplifier circuit 100 and a negative Class D amplifier respectively In this embodiment, the amplifying and driving circuit 200 is described by taking the positive class D amplifying and driving circuit as an example, and the working principle of the negative class D amplifying and driving circuit is the same as that of the positive class D amplifying and driving circuit.
[0022] The power amplifier circuit 1 receives the sound signal, outputs the signal after being amplified and processed by the power amplifier circuit 1, and inputs the s...
