iPhone7 Stereo High-Low Amplifier

thingiverse

Passive amplification truly revolutionizes audio output from tiny speakers. The iPhone7 boasts two stereo speakers, one at the top and another at the bottom of the phone face, significantly enhancing sound reproduction. This innovative amplifier cleverly positions pickups in both locations to deliver rich, doubled-amplified stereo sound. Moreover, many amplifiers are marred by tinny quality due to their swift cone expansion. In contrast, this exceptional amplifier focuses on length, with a 200mm pathway that expands an impressive 8 times over its distance. This strategic design allows high-band frequencies to amplify effectively and accurately. The mid and low-band frequencies receive equally meticulous treatment, boasting a 400mm path that expands 5 times over its length. The more gradual expansion along this longer path enables the low band to amplify with enhanced clarity. While it may not match the quality of a premium Bluetooth speaker, building one is undeniably a thrilling experience.
