Possibly the first baby triangular pyramid linoleum speaker is born

Made by Vicky.


It uses a tiny fullrange speaker. It should be great for examining how produced music would sound on mobile devices' internal speakers. But it may do a lot more.


How does it sound:
Worse than expected.


Firstly the 2in cheap drive unit was tried on air connected to iPad mini headphone out.
Very bad sound. No high frequency. No bass or mid. Only shrill.


Then 2 hands were used as baffle. Sound much improved in mid range.


Then in linoleum triple pyramid, much better than in air but worse than hands baffle.


Better quality drive units with lower reasonant frequency need to be found.
