how hole speaker circuit work
Answers
Answer:
At the center of the schematic we have the single "integrated circuit", or IC used in this circuit. This particular IC, LM386, is specifically designed to be used in audio amplifiers.
We've drawn it here as it appears in real life, so you can see which of the 8 legs is which. Notice how the numbers start on the top left, beside the notch and count up as you go counter clockwise. This is generally how the pins on ICs are numbered. The triangle in the middle is the schematic symbol for something called an operational amplifier. This will do the job of taking a small voltage waveform coming from your headphone jack and boosting it to a higher power waveform capable of driving a small speaker.
The lines on the schematics connect the components electrically.
