FPGA extended speaker problem

[Kitiyer]

Guys, I am an FPGA beginner, and the development board used does not have a buzzer speaker; now there are audio pulses that can be generated, and there is an urgent need to add a buzzer or speaker that can make sounds. There are GPIO pin headers on the board, I don't know how to connect the external speakers. Do you have any opinions?

Your question has nothing to do with Pro Audio/Sound Reinforcement. Suggest you find a forum that deals with FPGA.

Well, yes, I'm very sorry, I thought there was an answer here.

I found the answer，The audio signal is sent to the speaker after passing through the power amplifier. The common model of low-power audio amplifiers is LM386 TDA2822 (dual channel). Digital power is now more popular.
High-power common power amplifier IC: TDA2030
