| Summary, etc. |
Loudspeaker is one of electronic equipment that functioned by converting electrical energy into acoustical energy. Although the loudspeakers seem to have the same function, indeed, not all the system is alike. Each system has its own characteristic, types and functions. As for my active loudspeaker system, the system has its own circuit including crossover and built-in power amplifier. An audio signal can be produced just by connecting a source to the system. The crossover circuit applied in the system is placed between the input and power amplifier. It consists of two filters; low pass and high pass filter. They will split the signal into 2 frequency ranges; low frequency range (0 to 3100 Hz) and high frequency range (3100 Hz – 20000 Hz). After that, the power amplifier stage will increase the signal amplitude for about 20dB to 28dB. Both output signals will then be delivered to two speakers; tweeter and subwoofer. The tweeter will produce the high frequency sounds while low frequency sounds is produced by subwoofer. The system also has its own speaker protection circuit to prevent the speaker from broken down. Finally, an enclosure is constructed as the system platform to place the circuit along with the speakers. Certain guideline like the enclosure type and its appropriate dimension is followed to make sure the final product meets the earlier expectation. -Author |
