How To Make Headphone Amplifier with 3D Sound
this project is easy to create, by combining 3D sound processor module with TDA1308 Headphone Amplifier. audio from media player or smartphone feeding to 3D sound module for processing, there is a tactile switch to control on/off 3D, then audio output will go into the headphone amplifier. the amplifier output can be directly connected to drive the headphones. headphones with 32 ohm impedance can easily match with this amplifier. for power supply, its need 5 Volt DC voltage. in video above, I use Li-Ion battery and boosted to 5 Volt using DC converter buck.
