Earphone, corresponding sound source device and control method

Abstract

A wired earphone comprises an audio decoding unit, an audio processing unit, a power distribution unit and an audio device interface unit, wherein the audio decoding unit is used for decoding audio signal data flow; the audio processing unit is used for performing sound effect processing on audio signals; the power distribution unit is at least used for distributing electric power for the audio decoding unit or / and the audio processing unit; and the audio device interface unit is used for receiving the audio signals and electric power from an audio device in a wired connection mode.Provided is a sound source device control method.According to the method, the sound source device is connected with the earphone through a wired interface, and the sound source device selectively outputs digital audio signals having undergone audio decoding processing or / and sound effect processing according to functional characteristic parameters of the audio decoding unit or / and the audio processing unit read from the earphone.After the method is adopted, the sound source device and the earphone not only can be unified in ports, but also can be unified in functions, the same sound source device can adapt to earphones having different performances, the sound source device and the earphone support each other in functions and are reasonably expanded, more selections are supported, and optimum output is maintained.

Description

[0001] The present invention is a divisional application of Chinese patent application 201010298420.4, the filing date of which is October 2, 2010, and the title of the invention is "an earphone, a corresponding sound source device and a control method". technical field [0002] The invention relates to an earphone, a corresponding sound source device and a control method. Background technique [0003] Now, along with the development of technology, more and more sound source equipments such as MP3, DVD player, TV set, radio, telephone, mobile phone etc. appear in people's life, add fun to people's life. When using these devices, there are generally two ways to output audio, one is the speaker, and the other is the earphone. When using earphones as audio output devices, earphones are generally divided into wired earphones and wireless earphones; in addition, according to the channel, earphones are divided into mono earphones, binaural earphones (also known as stereo earphones...

AI Technical Summary

Problems solved by technology

However, there is only a simple connection between the audio source device and the earphone, and the audio source device cannot change the output signal according to the characteristics of the earphone.
