With the development of urban construction, it is necessary to improve the convenience of people\'s life and improve the safety of the public. In the past, the warning, reminder and alert were often done by sirens, alarms or loud speakers. However, the loud sound generated will bring discomfort to the citizen. Therefore, the SBM2 application field and working principle was designed to surpass traditional warning methods and provide a more effective way of notification.

SBM2 application field and working principles can be divided into three main parts, namely, alarm systems, buzzers and sirens. Alarm systems are used to warn people in general of potential dangers, or alert them to take precautionary measures, such as reminding people to wear safety equipment or evacuate a particular area. Buzzers and sirens act as the loudspeakers of these alarm systems and are commonly used to give a warning sound in case of emergency.

The alarm system usually operates on electromagnetic or pressure-sensitive elements. It can detect any pressure, changes in temperature and the presence of a foreign body. When the alarm system is triggered, the electromagnetic or pressure-sensitive elements activate the mechanically-activated switch, thereby activating the alarm.

The buzzer acts as a sound source that can produce a loud sound at a certain frequency when the electricity passes through. They are usually connected to the alarm system by a relay that amplifies the sound and directs it to the speaker. The frequency of the sound is determined by the power supply to the buzzer. It can be adjusted according to the purpose of the alarm.

Sirens are the most commonly used warning device in alarm systems. It consists of an electromechanical device that produces an intermittent sound at a certain frequency. When the sound produced is heard it signals danger to people in the area. The sound can be heard even from a long distance and can also be heard even when there is backgroud noise. The sirens usually work together with alarms in order to warn people in the area about any dangers.

SBM2 application field and working principle have been widely used in disaster and emergency situations. It is often used to warn people when there is a fire, or in extreme cases of natural disaster like floods and earthquakes. It is also used in everyday scenarios such as when there is a robbery or a security breach in a building. They can also be used in factories and warehouses to remind workers to take safety precautions before starting work.

SBM2 application field and working principle have made warning signals and alarms more efficient and reduced the discomfort created by loud noises. It has been especially useful in emergency situations, when quick response is needed to mitigate the risks of danger or harm. With the advancement of technology, these alarm systems are now being integrated with computer networks, which allows for quicker and more accurate responses in emergency situations.
