The invention relates to a novel trumpet connected by pulling and riveting a screw rod and a method for carrying out pulling and riveting fastening. Bracket connection in an existing vehicle electronic trumpet is threaded connection, and threads easily have the defects of corrosion, leakage, missing and the like, so that the fastening force at the threads is not enough, a bracket falls off, cost is high, the price is expensive, more production procedures are needed and the production rhythm is relatively slow. The novel trumpet comprises a shell (3), wherein a groove is formed in the shell; a screw rod (1) is mounted in the groove; a trumpet bracket (2) sleeves the outer part of the screw rod; the trumpet bracket is in pulling and riveting connection with the screw rod; a hollow knurl is arranged in the screw rod. The invention is applied to the novel trumpet connected by pulling and riveting the screw rod.
