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.

Description:


A buzzer is an audio signaling device, which may be mechanical , electromechanical , or piezoelectric (piezo for short). Typical uses of buzzers include alarm devices , timers, and confirmation of user input such as a mouse click or keystroke.
 
Piezo buzzer is an electronic device commonly used to produce sound. Light weight, simple construction and low price make it usable in various applications like car/truck reversing indicator, computers, call bells etc. Piezo buzzer is based on the inverse principle of piezo electricity discovered in 1880 by Jacques and Pierre Curie. It is the phenomena of generating electricity when mechanical pressure is applied to certain materials and the vice versa is also true. Such materials are called piezo electric materials. Piezo electric materials are either naturally available or manmade. Piezoceramic is class of manmade material, which poses piezo electric effect and is widely used to make disc, the heart of piezo buzzer. When subjected to an alternating electric field they stretch or compress, in accordance with the frequency of the signal thereby producing sound.
 
The piezo buzzer produces sound based on reverse of the piezoelectric effect. The generation of pressure variation or strain by the application of electric potential across a piezoelectric material is the underlying principle. These buzzers can be used alert a user of an event corresponding to a switching action, counter signal or sensor input. They are also used in alarm circuits.
The buzzer produces a same noisy sound irrespective of the voltage variation applied to it. It consists of piezo crystals between two conductors. When a potential is applied across these crystals, they push on one conductor and pull on the other. This, push and pull action, results in a sound wave. Most buzzers produce sound in the range of 2 to 4 kHz.
 
Our buzzers are widely used to inquartzcrystal clock, air-conditioner instrument, telephone, BP, copycat, alarm, instrument and apparatus, UPS power supply, motorcycle steering gear, electronic toy, computer terminal, electronic watch and etc.

Reliability test:

 

ITEM METHOD OF TEST STANDARD
Dry heat test

After being placed in a chamber with +70±2℃ for 96 hours and then being placed in natural condition for 2 hours, sounder shall be measured.

All specification must be satisfied after the test.

Cold test

After being placed in a chamber with -20±2℃ for 96 hours and then being placed in natural condition for 2 hours, sounder shall be measured.

All specification must be satisfied after the test.

Humidity Test

After being placed in a chamber with, 90%-95%R.H. at +40℃±2℃ for 96 hours and then being placed in natural condition for 2 hours, sounder shall be measured.

All specification must be satisfied after the test.

Temperature Cycle Test

After being placed in a chamber at -20℃±2℃ for 30 minutes, sounder shall be placed at room temperature(+20℃). After 15 minutes at this temperature, sounder shall be placed in a chamber at +70℃±2℃. After 30 minutes at this temperature, sounder shall be returned to room temperature(+20℃) for 15 minutes. After 5 above cycles, sounder shall be measured after being placed in natural condition for 2 hours.

All specification must be satisfied after the test

Vibration Test

Sounder shall be measured after being applied vibration of amplitude of 1.5mm with 10-55Hz band of vibration frequency for 30 minutes. Sweep time is 1 minute.

All specification must be satisfied after the test.

Shock Test

Sounder shall be measured after being applied shock (100G) for each three mutually perpendicular directions to each of 3 times.

All specification must be satisfied after the test.

Terminal Strength Pulling Test

The force 5 seconds of 5N is applied to each terminal.

No visible damage and cutting off.

All specification must be satisfied after the test.

Solder ability Test

Lead terminals are immersed in rosin for 5 seconds and then immersed in solder bath of +255±5℃ for 3±0.5 seconds.

All specification must be satisfied after the test.
