Abstract
A headset includes a pair of earpieces containing wide range speakers capable of outputting wide range sound, a printed circuit board and a connecting device connecting to the earpieces. The printed circuit board includes a receiver for receiving audio signal and transmitting the audio signal to a mixed circuit and a low pass filter. The low pass filter divides a low frequency audio signal from the audio signal and transmits the low frequency audio signal back to the mixed circuit. The mixed circuit adds the audio signal and the low frequency audio signal to from an enhanced low frequency signal and then transmits the enhanced low frequency signal to an amplifier. The amplifier amplifies the enhanced low frequency signal and transmits an amplified signal having enhanced low frequency effect to the wide range speakers. The wide range speakers transform the amplified signal to sound having bass effect.
