    Background noise can interfere with the sounds you hear coming through a set of earphones. To drown out the background noise, you may choose to turn the volume on your CD or MP3 player up to its maximum. But when even this is not enough, you may choose to add an inline amplifier.

    How an Amplifier Circuit Works

    • An audio amplifier circuit converts a small AC signal and turns it into a larger signal. An audio amplifier must reproduce the AC signal without distortion. Some amplifiers, such as the Class-A audio amplifier, waste energy by converting much of the input electrical energy into heat; therefore, if energy savings is a major factor, choose an amplifier based upon a small operational amplifier chip.

    Operational Amplifier Circuit Fabrication

    • An operational amplifier, or "op-amp" for short, is an integrated circuit which is capable of amplifying an AC signal without introducing distortion into the signal. The amplification factor, or "gain," in an op-amp circuit can be set by using two resistors connected to the op-amp input leads.
    • To fabricate an audio amplifier using an op-amp, you will need the following: one dual op-amp microchip (such as an LM833 Dual Operational Amplifier), one 1 Kiloohm resistor, one 10 Kiloohm resistor, a DC power supply (such as an alkaline battery), electrical wire, electrical pliers, electronic solder, and a soldering iron.
    • Cut six pieces of wire, and strip 1/2 inch of insulation from each wire end. Twist together one end of the first wire, the op-amp output lead, and one of the leads from the 10 Kiloohm resistor. Twist together the free lead from the 10 Kiloohm resistor, one of the leads from the 1 Kiloohm resistor, and the op-amp inverting input lead.
    • Twist together one end of the second wire, the free lead on the 1 Kiloohm resistor, and the "V-" (sometimes labled as "GND" or "V-EE") lead on the op-amp. Attach the free end of the second wire to the negative DC power supply terminal.
    • Twist together one end of the third wire with the non-inverting input lead. Twist together one end of the fourth wire with the "V+" terminal (which may also be labeled "V-CC") on the op-amp.
    • Connect the audio input to the free end of the third wire, and connect the earphone input to the free end of the first wire.

    How to Make Earphones Sound Louder

    Fanmusic MKII MK2 Portable Earphone Headphone Amplifier

    • Print this article Use a headphone amplifier to boost the audio level of your earphones.

    Make earphones sound louder using a headphone, or earphone amplifier. Many makes and models of headphone amplifiers offer a variety of features. All of them accomplish the same outcome of boosting the signal being fed to your earphones. Many headphone amplifiers allow you to power multiple sets of headphones, permitting several people to listen to an audio source at the same time.

    Instructions

    • Plug the output of your audio source into the input of your headphone amplifier. The type of audio cable needed depends on the output jack or jacks found on the device you listen through.
    • Plug your earphones into a channel on the headphone amplifier.
    • Adjust the gain, or volume control on the headphone amplifier to set the desired volume of your headphones. If the headphone amplifier has multiple channels, there will be a volume control for each headphone output.
