30mm Wire Passive Piezo Sound Buzzer

Wired passive piezoelectric buzzer is an electronic component that generates sound through physical vibration, and mainly works on the principle of piezoelectric effect.Piezoelectric effect refers to the accumulation of charge in certain materials when subjected to mechanical stress, and vice versa, that is, when these materials are subjected to electric field, they will deform. This characteristic is used in buzzers.     YY-11 1.Dia.30*5mm black color piezo sound buzzer.2.China professional electroacoustic manufacturer with 50 years history.3.Performance can be adjusted.4.Orange color wire.5.High quality.6.Used in car,electrical appliances.           Product Features *Brand Huasheng *Part number YY-11 *Dimension 30*5mm *SPL(Vocal cavity) more than 72dB *Insulation Resistance more than 1Mohm *Power sensitivity Less than 50mW *Operating temperature -20 ~+50℃ *Housing Color Black *Packing 1000pc…
