National Semiconductor has lots of possible solutions and a great selection of Application Notes. Maybe see if anything at this page looks suitable:

As a class 11 student, it's great that you are interested in amplifying audio using pencil cells. This can be a fun and educational project to learn more about electronics and sound amplification. Here are some steps you can follow to amplify audio using pencil cells:

1. Gather your materials: Besides the small mono speaker and pencil cells, you will also need a small amplifier board, a 3.5mm audio jack, and some wires. You can find these materials at your local electronics store or online.

2. Connect the audio jack to the speaker: Use the wires to connect the audio jack to the speaker. The audio jack will serve as the input for your audio source, such as your iPod.

3. Connect the amplifier board: The amplifier board will serve as the power source for your speaker. Connect the positive and negative terminals of the board to the corresponding terminals on the speaker.

4. Connect the pencil cells: Use the wires to connect the positive and negative terminals of the pencil cells to the corresponding terminals on the amplifier board.

5. Test it out: Once everything is connected, turn on your audio source and play some music. You should now hear amplified sound coming from your speaker.

Remember to handle the pencil cells with care and always dispose of them responsibly. You can also experiment with different types and sizes of pencil cells to see how it affects the sound output.

I hope this helps you amplify your audio and enjoy your music while traveling without using earphones. Keep exploring and learning about electronics, and don't be afraid to ask for help from your teachers or fellow students. Have fun!
