Frequency curve


Pins or wires type. Frequency is generally low. The mechanical buzzer is a special electromagnetic buzzer,composed of oscillator, the electromagnetic coil, the magnet and shell.Vibration piece is installed on the shell.

Applications for Buzzers:
Alarm devices
Confirmation of user input (ex: mouse click or keystroke)
Electronic metronomes
Annunciator panels
Game shows
Sporting events
Household appliances

Mechanical transducers

mechanical transducers have moving parts whereas phased array transducers does not. Mechanical transducers have only one crystal which is rocked side to side to create a sector image. Now think about this since the transducer is sweeping side to side that means that even at a high sweep speed the transducer cannot image the tissue continuously. For example when it rocks to the left it is not imaging the right and visa versa. This type of mechanism creates poor spatial resolution for this probe. Plus the fact that one crystal is sending and receiving the pulse as opposed to many with array systems. Since we have one crystal mechanically rotated there is no way to dynamically focus the the instrument therefore mechanical transducers utilize the conventional method of focusing which is a fixed focus. The fixed focus transducer cannot be manipulated therefore if we want to change the focus we must change the transducer. Mechanical transducers transducers are also responsible for creating the Side Lobe Artifact.

Mechanical buzzer

A joy buzzer is an example of a purely mechanical buzzer. They require drivers.

How to distinguish active and passive buzzer?

An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage.

A passive buzzer requires an AC signal to make a sound.

To identify them, if you apply a DC voltage to them and it buzzes, it's an active.
