Embodiment Construction

[0012] As shown in Figure 1, it is a hardware architecture diagram of the sound output system. The system includes a sound output device 10 and an audio output device 20 . In this embodiment, the audio output device 10 is an earphone as an example. The earphone 10 includes a memory 100 , a signal modem 102 , an analog interface 103 , a signal splitter 104 and an audio output unit 105 . The audio output device 20 includes an analog interface 200, a detection module 201, a signal modem 202, a signal separator 203, a characteristic parameter acquisition module 204, a memory 206, a microprogram control unit 207, and a signal output unit 208 . A signal adjustment unit 209 , a codec (CODEC) 210 and an audio signal amplifier 211 .

[0013] The analog interface 103 of the earphone 10 is connected to its signal splitter 104 . The memory 100 of the earphone 10 is connected to the signal modem 102 and stores the compensation characteristic parameters of the earphone 10 , and the compe...

Abstract

A method for outputting sound includes providing an analog interface by sound output unit, converting compensation character parameter stored in sound output unit to be high frequency parameter signal and sending it to audio output unit through analog interface, restoring high frequency parameter signal to be compensation character parameter and regulating audio signal as per said parameter then converting audio signal to be analog audio signal being outputted to analog interface of sound output unit and outputting sound corresponding to analog audio signal by sound output unit. A sound output system used for realizing said method is also disclosed.

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 spiritual life are getting higher and higher. Most of them like to enjoy music in their spare time. Therefore, audio output devices have become more and more popular, and the use of earphones has become more and more popular. The more widely heard the sound. [0003] The frequency range of the sound that can be heard by the human ear is generally 20Hz-18KHz, the frequency range of language is about 150Hz-4KHz, and the frequency range of various music is about 40Hz-18KHz; the energy of human voice is mainly concentrated in 200Hz- 35KHz frequency range. Therefore, in order to ensure the output of sound with good sound quality, the earphone needs to have a wide bandwidth and avoid signal delay. ...
