摘　　要：文章研究了音响放大器设计的4个主要部分,即语音放大器、混合前置放大器、音调控制器和功率放大器。首先对可行方案进行分析,然后分别设计各单元电路并计算相关元器件参数,最后在仿真软件中测试了相关技术参数指标,能够有效地保证声音质量,同时能够实现对音调的调节,验证了系统设计的可行性和有效性。该设计对于实际音响放大器的研究有一定参考价值。The design of audio amplifier is mainly divided into four parts, namely speech amplifier, hybrid preamplifier, tone controller and power amplifier. Firstly, the feasible scheme is analyzed, and then the circuit of each unit is designed respectively and the parameters of relevant components are calculated. Finally, the relevant technical parameters are tested in the simulation software, which can effectively ensure the sound quality and realize the adjustment of the tone, and verify the feasibility and effectiveness of the system design. This design has certain reference value for the actual sound amplifier research.
