麦克 (Màikè) is the most common Mandarin rendering of 'Mike' (also used for
麦克风 'microphone').
安斯林 (Ānsīlín) renders an '-Anslin/-Ainslie' surname; the syllable pattern matches both the Scottish surname Ainslie and the more obscure Anslin. The middle dot · separates the given name 'Mike' from the surname.
