Alarms, Buzzers, and Sirens
Alarms, Buzzers, and Sirens are devices that produce an audible signal usually like a steady high-pitched hum that is encased within a molded housing. The characteristics are driver circuitry, input type, voltage rated, voltage range, frequency, technology, operating mode, current supply, and port location. The technology is electromechanical, magnetic, piezo, and piezo (with feedback) with a frequency from multiple, 200Hz to 8kHz.
Buzzer Elements, Piezo Benders
Buzzer element products, also known as "benders," are composed of two conductive electrodes sandwiching a piezoelectric material, which exhibits a mechanical deflection when subject to an electric field; or conversely produces an electrical signal when subject to mechanical strain. Products of this type are primarily used to form compact audio signaling devices, often by attachment to the wall of a device's enclosure, which aids transmission of the vibrations produced by applying an electrical signal to the buzzer element into the surrounding air.
Microphones are transducers that convert sound into an electrical signal for storage, transmission and/or rebroadcasting. Ranging from large boom style microphones to small and popular MEMS types, they are differentiated by impedance, voltage rating, sensitivity, frequency range, port location, overall size and mounting type. Analog, I2S, PDM and TDM output interfaces are available.
Speaker products are audio frequency electromagnetic transducers used primarily to turn energy in the format of an electrical signal into mechanical compression waves travelling through an atmospheric air environment for reproduction of speech, music, or similar material. Products designed for general purpose reproduction of partial regions of the human audible frequency range (subwoofers, woofers, tweeters, etc.) are included, as well as full range products and special purpose transducers tailored for headset or in-ear applications.
