Mini amplificator piezo

Recommended Posts

Am nevoie de un amplificator cat mai mic ca dimensiuni care sa redea voce pe un difuzor piezo-electric. Are cineva vreo idee? Eu inca nu inteleg cum e cu aceste ?difuzoare? si nu stiu cum de un circuit de ala mic dintr-un ursuletz de pluş si o baterie asa mica scot sunete asa de puternice.. Eu am pus un un astfel de difuzor la un amplificator normal si trebuia sa ii dau la maxim sa ating aproximativ aceeasi putere (amplificatoru are vreo 25W) Astept si ceva lamuriri daca se poate. Tnx!

Mi se pare interesant dar nu am mai auzit ca un ursulet de plus care canta sa aiba 25W!! :rolleyes:

In principiu imi trebuie un amplificator ca pt o portavoce.. doar ca de dimensiuni mult mai mici.. si putere mica de asemenea. sa mearga la 3V maxim si sa fie cu ceva tranzistori smd... nu stiu daca pot sa fac cu transformator deoarece ocupa mult prea mult loc...Mai astept pareri
