WARNING SYSTEM BUILT-IN BUZZER

摘要

A warning system having a built-in buzzer is provided to reduce exposed connective lines and to simplify a structure thereof by installing a control unit and a small-sized chime buzzer in a main body case. A door locking switch(22) performs on/off operations according to the locking/unlocking states of a door. A door warning unit(32) receives power from a battery and transmits an operational signal to a control unit when the door locking switch is positioned in the on-state. A seat belt switch(24) performs on/off operations according to the coupling/decoupling states of a seat belt. A control unit(10) receives an operational signal from the door warning unit and the seat belt switch in order to control an alarm lamp and a chime buzzer(50) according to the locking state of the door and the coupling state of the seat belt. The chime buzzer receives an output signal from the control unit and generates alarm sound by using vibration of a sound plate due to magnetic force of a coil of an electromagnet. A main body case(100) includes the control unit and the chime buzzer. A connecting unit is connected to the control unit in order to connect the switches, the warning unit, and the alarm lamp.
