Hello Great work !!. Can you explain the amplifiers used in JBL Xtreme... Tronsmart Element Mega SoundPulse - They work at 8 V. There are many portable speakers that work at a similar voltage and brutally sound . Interesting that their battery lasts a long time. How did they manage to do that?

[@miguelluizgiacomelli3250]

Beleza mesmo! Ficou com uma sonoridade excelente. Muito gostoso de se ouvir. Parabéns pelo vídeo!

[@stevenA44]

Even thought this isn't built on a circuit board or breadboard, it looks pretty nice.

[@mdashiqurrahman39]

These types of general transistor base class a amplifiers are power eater and about 20-25% efficient. Also input should have 10-47k resistors connected with the gnd to reduce distortion and output should have 100nf series with 4.7-10 ohm resistors connected with gnd to bypass the high frequency.

firstly, thank you so much. Its really good. but i have a question. I didnt add the copper wire. And my amp's sound not much powerful as like yours. I wonder if the reason for this is that.

[@ScienceTechnologyExperiments]

May be you are using low voltage or low ampere power supply. Use 3 or 4 amps power supply and 12 to 18 volts dc. I think it will solve your problem. Thanks for watching & comments.

En las especificaciones del ic, siempre te darán la potencia de salida, así también los amperajes necesarios y el voltaje de entrada. Según entiendo (he buscado bastante), lo mejor, es tener un amplificador más potente de lo que soporta el altavoz, así se previene el clipping. Hay muchos otros problemas asociados a la mala elección del ampli y el altavoz, pero el clipping es uno de los más fáciles de solucionar.
