85dB SMD 5V Magnetic Buzzer / Surface Mount Buzzer 8.5*8.5*3mm For TV

85dB SMD 3V magnetic surface mounted buzzer for TV 8.5*8.5*3mm

Description:

A magnetic buzzer is based on the electromagnetic principle, the metal diaphragm is pulled when input the power, and spring back without power. And a passive buzzer emits a tone when a voltage is applied across it. Because it does not have built-in oscillating source, so it will not tweet if DC signals are used; instead, you need to use square waves whose frequency is between 2K and 5K to drive it.

Feature:

• They feature extremely low power consumption in comparison to electromagnetic units.
• Because these buzzers are designed for external excitation, the same part can serve as both a musical tone oscillator and a buzzer.
• They can be used with automated inserters.Moisture-resistant models are also available.

• The lead wire type with both-sided adhesive tape installed easily is prepared.

We suggest inputting higher voltage for a piezo buzzer, normally over 9V to have enough SPL. On the other hand, a magnetic buzzer can be driven to generate 85 dB by only 1.5V, but the consumption of the current will be much higher than Piezo one.

To compare the two types of buzzers(Magnetic and Piezo buzzer), the magnetic type can have lower frequency response with the same dimension. Though being limited by the dimension, the SPL of a magnetic buzzer can only reach to 90 dB. The piezo buzzer can achieve the SPL of 120 dB in some spec., some larger size can also easily reach to 100 dB.
