Test & measurement
A bass shaker works almost identical to an exciter. The most significant difference is that a bass shaker is based on the principle that the low bass frequencies can not only be heard but also be felt. The bass shaker has just as an exciter no diaphragm and uses the object it is attached to as a diaphragm instead. Here at SoundImports, you can buy bass shakers from well-known premium brands such as AuraSound, ButtKicker, Clark Synthesis, Dayton Audio, Monacor and Tang Band! For more information about bass shakers, check out the Dayton Audio tactile transducers buyers guide.
The object that a bass shaker is attached to is used to transmit low-frequency vibrations that physically can be felt. This is called tactile sound which gives a bass shaker also his nickname "tactile transducer". Usually, a bass shaker has an internal mass element inside a case, and the reaction force from vibrating the object the bass shaker is attached to creates the low-frequency bass vibrations. In an exciter, on the other hand, the mass of the motor structure stays fixed by its inactivity, and vibrating energy is moved directly to the surface by the voice coil.
The compact size makes most of the bass shakers almost invisible and is, therefore, a stylish upgrade for the home cinema. A popular spot to place a bass shaker is attached under the couch, a chair or a video gaming chair.
Feeling vibrations instead of hearing the bass? A bass shaker is driven by a voice coil which gets powered by a low-frequency audio signal from an amplifier. A bass shaker handles between 15 to 50 watts typically, but SoundImports also offers bass shakers that can hold up to 400 watts! The voice coil carries force onto the body and even the weight. The body forces being further transferred into the surface on which the bass shaker is being attached.
The technology of bass shakers sounds indeed impressive, but one might ask themselves for what occasion one might need an exciter. Bass shakers bring you one step closer in "becoming one" with the audio experience. Therefore, bass shakers attract lots of attention in home cinemas, in musical performance and in the gaming community. In the home cinema, for example, the primary use is to extend the bandwidth repeat the vibratory signature for the human voice, musical instruments or spectacular sound effects in movies. For musical performance, drummers often use bass shakers mounted on their drum stool so they can "feel" themselves playing – and so does the listener that has a bass shaker installed at home! Also, the gaming community has discovered the benefits of a bass shaker. They claim that bass shakers bring their gaming alive. Bass shakers are in high demand for racing simulators! Therefore, ButtKicker dedicated their mission to produce bass shakers in the focus of the gaming community.
