Abstract

The sound output system comprises a sound output device and an audio output device. The corresponding method comprises: detecting whether the sound output device is inserted into the audio output device; if yes, using the sound output device to send stored compensation feature parameter to another device; adjusting audio signal, sending signal to the sound output device; using latter to convert the signal into analog audio signal for output. This invention can ensure the effect of audio playback.

Description

【Technical field】 [0001] The invention relates to a sound output system and method, in particular to a sound output system and method with optimized characteristics. 【Background technique】 [0002] With the continuous improvement of people's living standards, people's requirements for the level of spiritual life are also getting higher and higher. Most of them like to enjoy music in their leisure time after tea and dinner, so audio output devices have become more and more popular. In order to listen to portable devices such as audio output devices conveniently, people listen to their voices through earphones, and with the improvement of living standards, users require that earphones can restore audio signals to lifelike sounds. [0003] Human voice and all kinds of music are random signals with complex waveforms. The frequency range of sound that can be heard by the human ear is generally 20Hz-20KHz, the frequency range of language is about 150Hz-4KHz, and the frequency ran...
