As illustrated in your photo, the transducer element (that sits immediately under the replaceable tip) may have suffered damage. Its relative position appears to be out-of-line with reference to the Pencil body.
Has the Pencil been dropped onto its tip, or suffered excessive lateral force? If the tip has been broken, one or other of these two scenarios is very likely - leading to potential damage to the transducer, this internal component being relatively fragile.
If the metal transducer element is intact - and importantly straight and perfectly in-line with the Pencil body - you can try replacing the tip, ensuring that the replacement is screwed snugly into position; you should see a tiny gap, of about the thickness of a sheet of paper, between the tip and pencil body.

If replacing the pencil tip does not resolve this issue, or the tip is not correctly positioned in relation to the pencil body when fitted, then your Pencil is likely to have suffered irreparable damage.
