2017.09.26, YAZAKI come to our company for on-site inspection and inspection. YAZAKI general manager personally led the quality, technology, procurement and other departments and a team of 5 people to my company on-site audit

Changzhou Cre-sound Electronics will attend Global Sourcing Fair 2017 from Oct. 11 to Oct 14. below is our booth information:

One Sweden customer need one element use for a personal alarm,his alarm sound is a sound wailing between 2khz and 5khz.The customer hope us to recommend one element so can reach maximum sound pressure.

SMD buzzer because of its ultra small, ultra-thin features, and its shape is square. Piezoelectric buzzer and electromagnetic buzzer can be subdivided into patches so its use and a buzzer, piezoelectric, electromagnetic, dedicated to a variety of telephone, clock, medical equipment, digital products, toys, office equipment, notebook computer, microwave oven, air conditioning, electrical appliances, equipment control panel etc.

Piezoelectric buzzer by pulse current on the piezoelectric ceramic to the vibration of the vocal sound, usually small, often in the side with an acoustic cavity; piezoelectric buzzer is mainly composed of multi harmonic oscillator, piezoelectric buzzer, impedance matching device and resonance box, shell etc.. Some piezoelectric buzzer on the shell is also provided with a luminescent diode from electromagnetic is through the moving part of the coil in the magnetic field of permanent magnet to for

Buzzer and speaker are the acoustic components that can generate sound, if you just need sound to warn or remind, both of them are fine.

The piezoelectric ceramic disc, can be equipped with a variety of ceramic product formula, made into different kinds of applications, products include: piezoelectric buzzer, bone conduction, touch, actuator, drive, transformer has the advantages of small, light, low power consumption and so on.

Buzzer is divided into piezoelectric and electromagnetic type of two categories, The piezoelectric buzzer is based on the piezoelectric effect, the vibration of the metal plate to drive the buzzer sound, is the use of electromagnetic principle, power metal diaphragm suction, no electricity in elastic diaphragm

The piezo element and the buzzer’cavity affect the frequency of piezoelectric buzzer.In theory, any frequency can be achieved, but in order to facilitate users to standardize products, the more common frequencies are 2KHZ and 4KHZ, the two types of frequency is the current mainstream.

Changzhou Cre-sound Electronics will attend Global Sourcing Fair 2017 from April. 11 to April. 14 We are sincerely welcome you come to our booth.

These products are hot items,production capacity can reach 3Million,they are exported to Europe ,Korea,USA and so on.
