Time is flying away, remember the first time we met in Ningbo in the year of 2005. I'm so happy with you and your team. Thanks for your support and let's look forward to the next years together.

—— Mr. Halit vergili

From partner to friend, you always give me surprise for your goods and service. We appreciate it so much. By the way, the pickled fish sauce is so nice. I'm self-confident of my cooking skills again. Don't forgot hot pot date next time.

Φ12*8.5mm split wire type passive electromagnetic buzzer 2048Hz

 

Description:

 

Electromagnetic buzzers featuring high reliability consists mainly of products that support automotive applications. They are directly mountable to PCBs due to their pin terminals, and are available in small φ12 type and φ16 type designed for broadband applications.

 

A passive buzzer emits a tone when a voltage is applied across it. It also requires a specific signal to generate a variety of tones.

 

Difference between two main types of buzzer: active and passive.
A passive buzzer emits a tone when a voltage is applied across it. It also requires a specific signal to generate a variety of tones. The active buzzers are a lot simpler to use, so these are covered here.
An active buzzer can be connected just like an LED, but as they are a little more robust, you won’t be needing a resistor to protect them.

 

Application:

 

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

Difference between piezo buzzer & magnetic buzzer:

A piezo buzzer generates sound because of the piezoelectric effect from the piezoelectric ceramic which drives the metallic diaphragm to vibrate.

A magnetic buzzer is based on the electromagnetic principle, the metal diaphragm is pulled when input the power, and spring back without power.

The piezo buzzer is driven by square waves, and the magnetic buzzer needs 1/2 square waves to drive.

 

Precautions for use:

 

• Do not supply any voltage higher than applicable to the buzzer.
• Do not use the buzzer outdoors. It is designed for indoor use. If the buzzer has to be used outdoors, provide it with waterproofing measures; it will not operate normally if subjected to moisture.
• Do not apply any mechanical force to the buzzer; otherwise the case may deform and result in improper operation.
• Do not place any shielding material or the like just in front of the sound release hole of the buzzer; otherwise the sound pressure may vary and result in unstable buzzer operation. Make sure that the buzzer is not affected by a standing wave or the like.
• Be sure to solder the buzzer terminal at 350℃ max.(80W max.)(soldering iron trip) within 5 seconds using a solder containing silver.
• Be careful not to drop the buzzer.
