Alarms, Buzzers, and Sirens

An alarm, buzzer, or siren is a device which produces a loud sound when activated, usually in order to alert people or other animals to a particular hazard or emergency situation. These devices are used in a variety of applications and come in many shapes and sizes, from the small electronic components found in cell phones to large fire alarms. The SCE048LD3SP1B is a typical example of an alarm, buzzer, or siren used in many common applications.

SCE048LD3SP1B Application Field

The SCE048LD3SP1B is a piezoelectric buzzer used in a variety of applications such as AC/DC power supplies, computers, consumer electronics, automotive systems, security systems, medical systems, industrial automation, vending machines, and many other applications. It is designed to meet the needs of various kinds of applications, with a wide operating range of 4V – 28Vdc.

SCE048LD3SP1B Working Principle

At its core, the SCE048LD3SP1B works on a principle called piezoelectricity. Piezoelectricity is the phenomenon in which certain materials (such as certain crystals and ceramics) produce an electrical charge in response to mechanical stress. When an electrical current is applied, the material vibrates, which generates sound.The SCE048LD3SP1B is composed of two main parts: a Piezo crystal and a magnetic coil. The Piezo crystal is located in the center of the device and vibrates when a current is applied to it. This vibration is amplified by the magnetic coil surrounding the crystal.The SCE048LD3SP1B is well-suited for a variety of applications due to its wide operating range, low current consumption, and good sound pressure level. It has a sound pressure level of 75dB at 10cm. This can be adjusted with an on-board trim pot, which can be used to increase or decrease the sound pressure level.

Conclusion

The SCE048LD3SP1B is a piezoelectric buzzer used in many applications such as AC/DC power supplies, computers, consumer electronics, automotive systems, security systems, medical systems and industrial automation. It operates on the principle of piezoelectricity, which is when certain materials (such as certain crystals and ceramics) produce an electrical charge in response to mechanical stress. The device is composed of a Piezo crystal and a magnetic coil, which work together to amplify the vibrations from the crystal. The SCE048LD3SP1B is well-suited for a variety of applications due to its wide operating range, low current consumption, and good sound pressure level.
