[0001] The utility model relates to the technical field of piezoelectric buzzer pieces, in particular to a convenient assembly structure of a square buzzer piece. Background Art

[0002] The current structure of the piezoelectric buzzer is to stick a piezoelectric ceramic sheet on a metal substrate. Silver paste is printed on both surfaces of the piezoelectric ceramic sheet as an electrode material. When a high-frequency AC signal is loaded onto the buzzer sheet, the piezoelectric ceramic sheet produces a corresponding regular geometric deformation due to the piezoelectric effect, driving the metal substrate to vibrate and produce sound.

[0003] Publication No. CN212010351U discloses a guide pin for a buzzer. The cross-sections of the guide pin and the card plate of the patent are closed figures composed of two arc segments and two straight segments. It is not easy to roll on the production line. The pin is passed through the top wall of the buzzer and screwed into the sleeve. The bottom wall of the card plate is pressed against the top wall of the buzzer. The card plate and the baffle increase the welding area with the solder, enhance the firmness of the welding, and ensure the stability of the main body; pull the pin rod, insert the bottom end of the buzzer into the sleeve, make the card block on the side wall of the buzzer snap into the arc-shaped card groove on the inner wall of the sleeve and release the pin rod. During the process of the spring returning to its original state, the baffle is pushed to move horizontally, so that the plug block is snapped into the arc-shaped card groove on the side wall of the buzzer, which is beneficial to the installation of the buzzer. Only by pulling the pin rod, the plug block is disengaged from the arc-shaped card groove on the side wall of the buzzer, which is beneficial to the disassembly and maintenance of the buzzer.
