Specific implementation mode
Come that the present invention will be described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not conflicting
In the case of, the features in the embodiments and the embodiments of the present application can be combined with each other.
Fig. 2 is the structural schematic diagram of earphone according to the ... of the embodiment of the present invention, as shown in Fig. 2, the earphone includes mainly：It raises one's voice
Device 22 and A/D samplers 24, wherein A/D samplers 24 are used to carry out sampling acquisition by the present impedance to loud speaker 22
The current voltage of loud speaker 22, the master controller 1 that current voltage is fed back to the user equipment being connect with earphone (please also refer to
Fig. 3).
In a preferred embodiment of the embodiment of the present invention, which can also include：Power amplifier 26, is used for
Audio data from master controller 1 is amplified, and amplified audio data is sent to loud speaker 22.
In embodiments of the present invention, it is preferable that the number of loud speaker 22 can be 1, accordingly, of A/D samplers 24
Number is also required to be 1；Certainly, in most cases, the number of the loud speaker 22 of earphone is 2, accordingly, of A/D samplers 24
Number samples the present impedance of each loud speaker 22 respectively to need 2.
Resonance is will produce when being placed in an enclosure space generally, due to the loud speaker of earphone, leads to the impedance of loud speaker
Become larger, and then its operating voltage is made to be more than the operating voltage at non-close space, that is to say, that when earphone is put into ear
It waits, ear just constitutes an enclosure space relative to earphone, at this point, the operating voltage of earphone is more than earphone not in ear
Operating voltage.Master controller 1 is according to the current voltage of loud speaker 22, it can be determined that and whether earphone is currently put into ear, from
And it can determine and the audio data of user equipment is exported via earphone or is exported via main loudspeaker (i.e. outside speaker).
