Technical Field

[0001] The utility model relates to the technical field of electronic buzzers, in particular to an electronic buzzer which is easy to repair. Background Art

[0002] An electronic buzzer primarily consists of a small number of electronic components and a piezoelectric speaker. The operating principle of an electronic buzzer is based on the piezoelectric effect. When an external voltage is applied to a piezoelectric ceramic crystal, the crystal generates mechanical vibrations, which in turn drive air vibrations, producing sound. This sound is amplified and emitted by the buzzer's resonant cavity. Although the electronic buzzer's circuit structure is simple, it includes components such as a transformer, resistors, transistors, switches, power supplies, and capacitors. Together, these components form a self-oscillating circuit, enabling the buzzer to continuously emit sound.

[0003] Electronic buzzers are widely used in various electronic devices and systems for purposes such as reminders, warnings, notifications, and control. After a period of use, electronic buzzers need to be repaired to prevent malfunctions. Existing electronic buzzers require tools to disassemble them for repair, which is time-consuming and inconvenient. Therefore, an electronic buzzer that is easy to repair is proposed.
