Abstract
The invention relates to a car alarm with a piezoelectric ceramic buzzer piece pressed through ultrasonic welding. At present, an internal structure of the alarm is not provided with the piezoelectric ceramic buzzer piece fixed through ultrasonic welding. The car alarm is easy to process, the reliability of a pressing structure is improved, and the processing cost and the processing time are reduced. The car alarm comprises the piezoelectric ceramic buzzer piece (1) and is characterized in that the piezoelectric ceramic buzzer piece pressed through the ultrasonic welding of the car alarm is arranged in one region through pressing parts, and then the upper pressing part (2) and the lower pressing part (3) are welded through the ultrasonic welding. The piezoelectric ceramic buzzer piece is used for the car alarm.
Description
technical field:
the present invention relates to a kind ofly for alarm field, be specifically related to a kind of connected mode of new construction.
