Abstract: A handheld electronic device includes a first speaker, a second speaker, and an audio controller. The audio controller includes a signal receiving unit, a frequency crossover unit, a harmonic-wave generating unit, a low frequency enhancement unit, and a signal synthesis unit. The signal receiving unit receives an original sound signal and generates a first channel signal and a second channel signal according to the original sound signal. The frequency crossover unit sets a preset frequency crossover point to filter the first channel signal to generate a low frequency signal. The harmonic-wave generating unit generates harmonic waves according to the low frequency signal. The low frequency enhancement unit generates an enhancing low-frequency signal according to the harmonic waves. The signal synthesis unit generates a first channel enhanced signal according to the enhancing low-frequency signal and drives the first speaker.

Abstract: A sound quality evaluation method and a sound quality evaluation system using same are provided. The sound quality evaluation system records playback of a test audio file on a plurality of playback devices to generate a plurality of pieces of audio data, and divides the audio data into a plurality of frequency bands. The sound quality evaluation system calculates the frequency bands to obtain a plurality of evaluation scores of the playback devices. The sound quality evaluation system captures sound quality ranking information corresponding to the playback devices from a reference source, and adjusts the evaluation scores according to the sound quality ranking information, to further obtain a reference model. The sound quality evaluation system adjusts correspondingly evaluation scores of a plurality of to-be-tested playback devices according to the reference model, to obtain sound quality ranking information of the to-be-tested playback devices.
