Button-operated sound toys

Overview

Recently, there have been many button-operated sound toys on Bilibili,
and some friends also wanted to customize the audio,
so this project was created. It makes a sound
when pressed, with not many functions.
The speaker was just randomly selected from the library; you don't need to buy according to the BOM list (but LCSC's online store is convenient and hassle-free). The chip used is the SZY13P005J chip; you can buy it by searching for "audio IC" on Taobao (the seller provides free burning and a capacitor speaker). (Very durable)
. It's very cheap and affordable. LCSC provides 5 PCBs at a time, and the IC seller provides 5 ICs at a time (to prevent clumsy attempts). Soldering is extremely difficult (you can even just plug it in without soldering). Suitable for beginners to replicate.
Detailed tutorials (to be released within a week) can be found on Bilibili: @XC若雨 (follow 若雨喵, thank you!).
