Your english is good enough, do not worry!
You did a fine job making a "flyback" transformer plasma speaker, very good audio quality with almost no distortion. That is not easy.
Making a tesla coil is far more difficult than making a flyback transformer work, and getting a tesla coil to play music is another level of difficulty in addition. Tesla Coils are what is known as a "high Q system", which means a very small change in any variable makes a huge change in performance. Typically you make a plasma speaker by modulating either the supply power or the drive dignal of a high voltage transformer. Most people do it by modulating the drive signal as this does not require high power audio and a very large modulation transformer, but there is a draw back; in order to get good audio out of the tesla coil it takes a large variation in drive signal. High Q systems often begin to suffer big losses or just plain fail when you vary a drive signal significantly. So it is a very complex process to correctly design a working musical / audio tesla coil. Building it is a challenge to even the most experienced.
My advice; read up on tesla coil theory and principles in your native language (if you tell us what that is we might be able to give you the right direction to look in). Then read up on "Class-E topology for inverters and amplifiers" as well as the "half bridge inverter" and "H bridge inverter". Once you have a basic understanding of these systems you can begin to piece together how they fit together with a basic tesla coil to make the SSTCs we make today.
As for your plasma speaker with the flyback, you can only get louder audio out of it by increasing the input voltage and drawing a larger arc to move more air volume. Try 24V if you can, but remember that depending on what ICs you use they may not survive anything over 15V. I would need to see your schematic to tell you if it can handle more power.
Again, nice job!
