Cre-sound Electronics is a Chinese manufacturer with more than 25 years of experience in manufacturing electromagnetic and piezoelectric sound transducers.
The supplier’s offer includes a particularly noteworthy product, i.e. electromagnetic buzzers, which are available directly from the TME warehouses. They come in a variant with an integrated generator, thanks to which the need to modulate the input signal can be avoided. Another variant that is available from our catalogue is the version without a built-in generator. To activate such a buzzer, it is necessary to provide a control signal of the required/desired frequency. The range of supported frequencies spans from 2 kHz to 4 kHz (it varies from product to product). The generated sound level is from 78 dB to 95 dB, and the supply voltage covers the range from 2 V DC to 16 V DC.
The electromagnetic buzzers from Cre-Sound Electronics are designed for surface (SMT) and through-hole mounting (THT). Thanks to their small size and wide operating temperature range, they can be broadly applied in compact devices, sensors, alarms, etc.
