How Do You Increase The Input Impedance Of Computer Speakers?
Speakers are used to convert alternating current audio signals into mechanical sound waves. As electrical current moves through the speaker coil, a magnetic field is induced across the coil, which moves a permanent magnet in the speaker cone. This action carried out over a period of time will move the surrounding air, causing the formation of a sound wave. Speaker coils present a low level of impedance (typically between 4 and 16 ohms) across the speaker leads. Some audio amplifiers require a high-impedance load to transfer as much power as possible to the speaker. Use an impedance-matching transformer to increase the impedance of a small speaker, such as a computer speaker. Cut eight pieces of wire, and strip one-half inch of insulation from each wire end. Solder one end of the first wire to one of the primary terminals on the first transformer. Solder one end of the second wire to the other primary terminal on the first transformer. Solder one end of the third wire to one of the seco
