What is an exciter?
An exciter, also known as a body shaker, is a speaker that consists of neither a cone nor a frame. It merely functions by vibrating a rigid surface that got taped or screwed on to create sound. Their size makes them almost invisible and is the perfect option when the shape or size of an ordinary speaker is an issue. Try a few on doors, ceiling panels, windows, projection screens—whatever excites you! Here at SoundImports, you can buy exciters from quality brands such as Dayton Audio, Monacor, Tectonic Elements and Visaton.

How does an exciter work?
A typical exciter includes a voice coil, electrical connection terminals, a suspension system, a motor assembly, and an adhesive ring or coupling plate, which attaches the exciter to the mounting surface. At the point when a signal is sent to the exciter, the unit starts to vibrate at the frequency of the signal, and those vibrations move through the exciter's mounting surface along these lines transmitting sound - the outcome is surprisingly melodic and accurate. Sounds amazing; however, for what reason would you utilize an exciter. Next to the mentioned advantages of their size when space is an issue, body shakers have another distinctive element - exciter technology is a financially smart option compared to standard speakers that permit sound multiplication practically anyplace it is wanted.
Where do you use an exciter?
Exciters can be used almost everywhere. However, it is crucial to be aware of the fact that every surface sounds different. A body shaker mounted on a wooden desk will create a different sound than an exciter mounted onto a glass door. Size also matters – a wooden floor will create a different sound image than the mentioned wooden desk. Once you have decided on a material and a location, the next decision should be the right type of exciter since there are several types of exciters, each with its own benefits and features. However, the selection of an exciter is connected to several factors and questions regarding the application surface and its substrate, size and weight of the mounting surface coverage area and desired sound result.

What are flat-panel speakers and how do they work?
Another field of application for exciters is for so-called DML or flat-panel speakers. DML stands for Distributed Mode Loudspeakers and is a term for speakers that catch the eye with their incredibly slim design. The motor of a so-called DML speaker functions similarly to ordinary speakers with the difference that it vibrates a basic panel — made of plastic, metal, composite, or another material — and does away with the complicated structure of traditional speakers. To generate sound waves, the entire panel vibrates.
A popular way of displaying DML speakers is by covering their cases as paintings or pictures and hanging them onto the wall. However, one should be aware that a pair of DML speakers will not reach the sound quality of floor standing audiophile HiFi speakers; physical laws also apply to DML speakers. However, DML speakers can have an extraordinary sound quality for their size. They are used in situations where full-sized speakers either do not fit or would distract the furnishing of a room. One of the most popular application fields for DML speakers is the rear speakers from a home cinema, where ordinary rear speakers do not fit behind the couch!
