Abstract
A driving circuit for an audio power amplifier and an electronic device are provided. The driving circuit includes an audio codec, an audio power amplifier (PA), a power management integrated circuit (PMIC), a transistor, a speaker, and a motor. The transistor is connected in series with the motor to form a combined body, the speaker is connected in parallel with the combined body to form a two-in-one device, the audio PA is connected in series with the two-in-one device, the PMIC is connected in series with the two-in-one device, and the audio codec is connected in series with the audio PA. In the technical solutions provided in embodiments of the disclosure, a power amplifier can drive both the motor and the speaker, so that a power amplifier may be omitted and the power consumption and cost of the electronic equipment may be reduced.
