A passive walnut speaker that amplifies phone audio through carved wood alone.
Echo of Nature is a hand-carved wooden object that passively amplifies sound from a smartphone speaker without electronics, batteries, or wires. The project explores how material, cavity shape, and hand-crafted form can shape perceived warmth and resonance through purely physical means.

Acoustic Premise
The project started with a simple acoustic challenge: to amplify phone audio without using electronics. Echo of Nature uses a carved wooden chamber to direct sound outward, turning the object itself into a passive amplifier.
Chamber Logic
Several small prototypes were made to test chamber depth, opening size, and phone placement. Each version adjusted how sound moved through the object, helping define the final shape of the hollow walnut body.
Hand Craft
The final piece was cut, carved, and sanded by hand from solid walnut. The phone slot was sized to fit the intended device closely, reducing sound leakage between the speaker output and the chamber. Contact areas were smoothed while the outer surface kept a more natural material character.
Acoustic Outcome
The final object demonstrates how chamber depth, material density, and speaker alignment can shape phone audio into a warmer and more directional listening experience.
