Buzzer by means of buzzer (6)

I believe the answer is:

beeper

I'm a little stuck... Click here to teach me more about this clue!

'of buzzer' is the definition.
The definition suggests a singular noun which matches the answer.

'buzzer by' is the wordplay.
'buzzer' becomes 'bee' (insect which buzzes).
'by' becomes 'per' (I've seen this in another clue).
'bee'+'per'='BEEPER'

'means' is the link.

Can you help me to learn more?

(Other definitions for beeper that I've seen before include "pager, perhaps" , "electronic device" , "Electronic alarm" , "pager, eg" , "Emitter of electronic sound" .)

I've seen this clue in The Guardian.
