Vehicle horn is a kind of electro acoustic device. The energy transfer process were analyzed through the energetic coil current, magnetic force, and displacement curves which had gotten before, and the process was happened in stage of the action, transaction and reciprocating vibration. The reasonable criterion for checking reciprocating vibration and sounding of horn was proposed, and the criterion was proved by changed the design parameters. The conclusions are of great value for further optimizing of reliability of the electro acoustic device such as electromagnetic horn.
