I won't use crystal earpiece.I will modify it and i'll give sound from mp3 player ......

Presumably you're aware that AM quality is absolutely abysmal?, and that the crude circuit above will likely produce very little modulation?.

Why do you want to do this with AM instead of FM?.

Because already i built a fm transmitter it is very nice and works very well but i want to learn another modulation

Well you're not, both the normal VHF ones and that 'AM' ones do a crude mixture of FM and AM.
