## Abstract

In this device, three chambers, three chips with multiple holes and three membranes senses and magnifies sound signal from miles away to a magnitude that can be heard by device holder. Sound wave enter from the membrane, vibration energy is transmitted by highly compressed air within chamber 3, which then is magnified by multiple small holes in its chip. The same vibration is magnified by compressed air in chamber 2, which then is magnified by multiple small holes in its chip. Then the vibration is magnified by compressed air in chamber 1, which then is magnified by multiple small holes in its chip. Device holder adjust the air density in chamber 1, 2 and 2 by sliding chamber 3 inside chamber 2, and by sliding chamber 2 inside chamber 1. Sound wave is magnification in proportion to air compression ratio between two connected chambers, and magnified by holes on each of the three chips, thereby sound wave received from miles away is tremendously magnified.

## Claims

### Claim 1

A new method to magnify sound wave mechanically by filling three connected chambers with chips with multiple holes, compressed air, sound sensing membrane, and by sliding three connected chambers to adjust compress air pressure to a peak ratio.
