FBelec magnetic sounder has several parameters, some of which are also parameters in the Piezo Buzzer circuit, such as voltage, current, and so on. In addition to these, FBelec buzzer 's sound has certain parameters as a sounding device. FBelec concepts of audio frequency and sound pressure of the piezo sounder will then be introduced briefly.

FBelec buzzer's audio frequency is the sound wave frequency of the sound emitted by the buzzer, which is the number of continuous cycles contained in each second. Hertz is the frequency measurement unit (Hz). FBelec frequency range of human hearing is approximately 20-20KHz. Infrasound waves less than 20Hz and ultrasonic waves greater than 20KHz.

FBelec resonant frequency of the buzzer's most commonly used product is 2-4khz. The Piezo Audio Indicator's resonant frequency refers to the frequency point with the highest recommended use and good sound pressure consistency. FBelec frequency of the Audio Devices determines the sound tone of the corresponding product. The lower the tone, the lower the frequency of the sound. The electro-magnetic buzzer 's sound pressure is the rated working signal at both ends of the buzzer, and the DBA value is measured at a distance of 10cm from the sound pressure level. The unit of sound pressure is the decibel (DB). The higher the number of decibels, the louder the sound.

We can learn that the audio frequency and sound pressure of the self-drive piezo buzzer determine the human feeling after the buzzer's sound is received by the human ear, that is, whether the sound we feel is large or not, and whether the sound is sharp or not. You will understand these two concepts better this way.

A Piezo active buzzer connected directly to a DC power supply can do the following: High sound pressure, high sensitivity, low power consumption (generally less than 20ma and no more than 100ma), good reliability, low power consumption, and no circuit are all advantages. Security, air conditioning, refrigerators, instrumentation, reversing radar, microwave ovens, printers, copiers, alarms, electronic toys, automotive electronics, green circuit boards, telephones, timers, audio equipment, automobiles, supermarket gating, and other electronic products are the primary applications.
