[0061] Embodiment 2
[0062] On the other hand, an embodiment of the present invention provides a mobile terminal, where the mobile terminal includes the earphone circuit described in the first embodiment.
[0063] Specifically, the mobile terminal may be a smart phone, a tablet or a notebook computer.
[0064] The beneficial effects brought by the technical solutions provided in the embodiments of the present invention are:
[0065] 1) By setting the capacitor module, the antistatic performance of the earphone is improved.
[0066] 2) By setting the inductance module, better impedance characteristics can be presented at high frequencies.
[0067] 3) By setting the filter module, it will not only have no obvious impact on the effective audio frequency, but also can effectively suppress the harmonics to achieve the purpose of improving anti-interference and distortion.
[0068] Under the guarantee of the electrical characteristics and performance of the headset, the anti-int...
