[MAX98357A] Changed IC package of class D amplifier from TQFN to WLP

The MAX98357A series of ClassD audio amplifiers is available in TQFN and WLP packages. The WLP package is smaller and more cost-effective than the conventional TQFN package, as it does not require expensive through-hole vias (connection pins that pass through the PCB).

[Speaker] I attended the workshop on acrylic speaker amplifiers. I learned a lot.

I decided to start a speaker business for the hearing impaired in January this year, so this workshop came at the right time when I wanted to deepen my understanding around speakers.
