An audio playing system has a first channel output device, a first equalizer, and a controller. The first equalizer is configured to adjust a received first channel audio signal with a set of first parameters of frequency response and output the adjusted first channel audio signal to the first channel output device in a first mode, and to adjust the received first channel audio signal with the a of second parameters of frequency response and output the adjusted first channel audio signal to the first channel output device in a second mode. In a test mode, the controller is configured to send a set of test audio signals to the first channel output device and to adjust the set of first parameters of frequency response and the set of second parameters of frequency response based on a plurality of pieces of received first confirmation signal.

Audio playing system

An audio playing system has a first channel output device, a first audio modulator and a controller. The first audio modulator is electrically coupled to the first channel output device and having a set of first modulation parameters, the first audio modulator configured to selectively modulate a first channel audio signal with the set of first modulation parameters and output the modulated first channel audio signal to the first channel output device. The controller is electrically coupled to the first channel output device and the first audio modulator, wherein in a test mode, the controller is configured to send a set of test audio signals to the first channel output device, to generate a set of first user parameters based on a plurality of pieces of first confirmation signal, and to adjust the set of first modulation parameters based on the set of first user parameters.

Audio playing system capable of automatically personally compensating

An audio playing system has a first channel output device, a first equalizer and a controller. The first equalizer is electrically coupled to the first channel output device and having a set of first parameters of frequency response, the first equalizer configured to adjust a first channel audio signal with the set of first parameters of frequency response and output the adjusted first channel audio signal to the first channel output device. The controller is electrically coupled to the first channel output device and the first equalizer, wherein in a test mode, the controller is configured to send a set of test audio signals to the first channel output device, to generate a set of first user parameters based on a plurality of pieces of first confirmation signal, and to adjust the set of first parameters of frequency response based on the set of first user parameters.

An audio playing system has a first channel output device, a first equalizer, a second channel output device, a second equalizer, a loudness adjusting button, and a controller. The first equalizer adjusts a first channel audio signal with a set of first parameters of frequency response and output it to the first channel output device. The second equalizer adjusts a second channel audio signal with a set of second parameters of frequency response and output it to the second channel output device. The loudness adjusting button generates a loudness instruction. The controller determines an upper limit of loudness based on the set of first parameters of frequency response and the set of second parameters of frequency response, and adjusts a loudness related to the first channel audio signal and a loudness related to the second channel audio signal based on the upper limit of loudness and the loudness instruction.
