Sometimes the transducer is itself referred to as a speaker, particularly when a single one is mounted in an enclosure or as surface-mounted device (as in a wall-mounted speaker, car audio speaker, and so on). There are many different types of speaker drivers. The most common ones are the woofer, mid-range and tweeter, as well as subwoofers which are becoming very common. Less common types of speaker drivers are supertweeters and rotary woofers, a new technology that is still proprietary of Eminent Technology.\u0026lt;\/td\u0026gt;\u0026lt;\/tr\u0026gt;\u0026lt;\/table\u0026gt;] cssheader=[boxoverheader] cssbody=[boxoverbody]\"\u003edriver\u003c\/span\u003e, 38 mm (1.5 in) \u003cspan class=\"dictionary\" title=\"header=[\u0026lt;span class=boxoverheaderplain\u0026gt;Definition of\u0026lt;\/span\u0026gt; Voice Coil:] body=[\u0026lt;table width=400\u0026gt;\u0026lt;td\u0026gt;The voice coil is the coil of wire fixed to a cylinder at the apex of the loudspeaker cone that interacts with a magnetic field. With the help of other speaker components, the voice coil is the active transducer that converts electrical signals from the amplifier or receiver into mechanical energy, which we hear as sound. The voice coil cylinder is the part of the speaker around which the voice coil is wound. More advanced speakers offer a heat-resistant voice coil to prolong speaker life.\u0026lt;\/td\u0026gt;\u0026lt;\/tr\u0026gt;\u0026lt;\/table\u0026gt;] cssheader=[boxoverheader] cssbody=[boxoverbody]\"\u003evoice coil\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"spec\"\u003eHigh-\u003cspan class=\"dictionary\" title=\"header=[\u0026lt;span class=boxoverheaderplain\u0026gt;Definition of\u0026lt;\/span\u0026gt; Frequency:] body=[\u0026lt;table width=400\u0026gt;\u0026lt;td\u0026gt;The number of times a periodic waveform cycles, or repeats, over a period of time.\u0026lt;\/td\u0026gt;\u0026lt;\/tr\u0026gt;\u0026lt;\/table\u0026gt;] cssheader=[boxoverheader] cssbody=[boxoverbody]\"\u003eFrequency\u003c\/span\u003e Waveguide\u003c\/span\u003e: Crossfired Waveguide\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"spec\"\u003eFinish\u003c\/span\u003e: Black DuraFlex finish.
