DMG speaker adapter for larger 23mm speakers

thingiverse

This speaker ring was designed to retrofit a 23mm speaker into the 29mm speaker housing in the original Game Boy DMG-01. It was modified for the GHXamp 23mm 8ohm mini full-range loudspeaker. I use this speaker in Game Boys modded with a class D amp. The speaker carries the markings "YD-2353F". You can purchase them from the GHXamp store on Aliexpress: https://www.aliexpress.com/item/33010437360.html?spm=a2g0s.9042311.0.0.27424c4dL3QepF The original design only worked for shallower speakers, and with the original Retromodding design, the case wouldn't close. I recreated the shape of the original, removed the rear flat piece, allowing the speaker to be placed flush with the collar, and cut out two channels for the speaker terminals, soldered on the outer edge of the speaker. By the way, the flat side faces the inside of the game boy. The angled cut goes out toward the player, in the bottom left edge where the case is slightly angled.
