It's Luna Lovegood, she has the hare patronus.
She doesn't have a phone, she's a witch.
They are Spectrespecs, used to see 'wrackspurts', which according to Luna are creatures that float in through your ears and make your brian go fuzzy.
If you have a post-owl, it will deliver her your letter without an address. Otherwise you have asked the wrong question.
