Miniature loudspeakers can be customised for music or speech, for example, and are used in headsets, headphones, hands-free units, Bluetooth headsets, digital cameras and recording equipment.
The most common are dynamic speaker elements in which a coil attached to a diaphragm moves in an air gap with a concentrated magnetic field. Loudspeakers are available with single and double coils and with an aluminium or copper core. A current through the coil creates a mechanical force which moves the diaphragm/coil proportionally to the current, thus creating a sound wave.
Mini speakers can be customised for music or speech, for example, and are used in headsets, headphones, hands-free units, Bluetooth headsets, digital cameras and recording equipment.
Dynamic speaker elements can be designed to reproduce the entire frequency range or just parts of it (bass, mid-range, treble, etc.). In addition, we can adapt them in production to specific requirements in terms of their characteristics, including impedances of up to 600 ohms.
