Surface Mount Buzzer Common Specifications and Application Fields Surface mount buzzers, due to their ultra-small, ultra-thin design and square shape, are commonly used in various applications. Both piezoelectric and electromagnetic buzzers can be subdivided into surface mount buzzers, so their uses are similar to those of piezoelectric and electromagnetic buzzers, specializing in telephones, clocks, medical equipment, digital products, toys, office equipment, laptops, microwave ovens, air conditioners, household appliances, and equipment control panels, among others.

Surface mount buzzers are commonly available in diameters of 5.0mm, 7.5mm, 8.5mm, 11mm, 14mm, 17mm, with frequencies typically ranging from 2.3kHz, 2.4kHz, 2.7kHz, 3.6kHz, 4kHz, to 4.1kHz and beyond.
