Electromagnetic Transducers

Electromagnetic sound generators consist of a swinging metal diaphragm driven by an electro-magnetic circuit. These transducers are small and provide a wider frequency range compared with piezoelectric sound generators. They are the right choice for applications, where different frequencies are used to create different sounds.

Typical applications are kitchen devices, medical and health care accessories, cellular phones, PDS, etc. In general, electro-magnetic sound generators have a higher current consumption than piezo sound generators but they need lower voltage to achieve their maximum SPL output.
