LU XIANG / No electricity Speaker


The aluminum speaker consisted of identical units includes a resonance box, which requires no electricity.

As current speakers in the market only transmit audio to single direction and require electricity, this speaker transmits audio from mobile phone to multiple directions with longer distance due to the highly reflective aluminum material.

Comparing to current products available in the market, this speaker utilizes aluminum alloy to reveal a sense of quality without heavy weight.
