Technical Field

[0002] Nowadays, mobile speakers have been widely used in many different occasions, but most of the mobile speakers on the market are mainly composed of built-in batteries and speakers. The performance of the audio amplifier directly affects the sound quality of the entire mobile speaker. At present, the power amplifier system of mobile speakers has different powers, and different places use power amplifiers of different powers. The audio power amplifier often uses a constant power supply voltage, which causes the volume of the audio to be low during playback, resulting in a decrease in the efficiency of the audio power amplifier.

[0003] For example, the patent with application number 202320885678.7 discloses a high-power battery-powered mobile speaker amplifier system, wherein the amplifier system is connected to the load speaker and battery power supply of the mobile speaker respectively, and includes a DCDC module, a voltage stabilizing module and several amplifier modules, wherein the DCDC module is provided with a DC buck module and a DC boost module, wherein the DCDC module transmits the output voltage signal to the amplifier module, and the amplifier module is connected to the load speaker; the amplifier module is used to amplify the power of the signal processed by the DSP processing module and drive the load speaker to play; the voltage stabilizing module is used to maintain a constant power supply output voltage; and the battery power supply is used to power the amplifier system. The high-power battery-powered mobile speaker amplifier system provided by the utility model realizes high-fidelity audio output, thereby improving the efficiency of mobile speaker amplifier processing.
