The Analog Tele-Phonographer is a passive acoustic audio amplifier made for iPhone or iPad, using salvaged brass instruments, stainless steel, and surplus machine parts. Analog Tele-Phonographers use no batteries, electricity, cables, or electronics. They simply harness the sound coming from your device’s built-in speaker, and provide a louder, warmer, richer tone.
