Abstract

The invention provides a type of earphones which comprise a nonvolatile earphone functional characteristic storage device, wherein the storage device stores functional characteristic parameters of the earphones; and the functional characteristic parameters at least comprise impedance information of the earphones. The invention provides a control method for sound source equipment. The method is characterized in that the sound source equipment comprises a reading module for earphone functional parameters; when the sound source equipment is connected to the earphones, the reading module for the earphone functional parameters can read the functional characteristic parameters of the earphones; the functional characteristic parameters comprise the impedance information of the earphones; and the sound source equipment selects a proper volume and outputs the volume to the earphones according to the impedance information. Through application of the method, the sound source equipment and the earphones can have uniform interfaces and uniform functions; the same sound source equipment can be suitable for earphones with different types of performance; mutual supporting and rational extension of functions are realized; more choices are applicable; and optimal 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...
