The BCT-3 bone conduction transducer from Dayton Audio can produce sound through direct vibration of the bones in the head. Also, this powerful exciter is capable of converting surfaces into speakers via vibration when placed on materials such as desks, walls, doors, and many other solid materials.
Highlights
- Creates sound through vibration transmission
- Turns nearly any surface into a speaker
- Wide 300 to 20,000 Hz frequency response
- Allows you to hear without disturbing others around you
Product Details
Dayton Audio BCT-3 44 x 32mm Bone Conducting Transducer
Unlike conventional transducers that use moving air to produce sound around you, Dayton Audio BCT-3 bone conducting transducer converts the electrical signal into mechanical vibrations so clean, that the brain interprets the vibrating stimulus as excellent sound. Install this exciter to a solid surface, such as a molded headrest, and high-fidelity sound will appear from seemingly nowhere when your head touches it. Your ears are left free to remain aware of their surroundings, greatly increasing personal safety.
When used against materials such as cardboard, wood, steel, and plastics, the BCT-3 operates much like a surface exciter and is capable of moving mass to produce robust sound output; much like an invisible speaker! The BCT-3 is excellent for unique OEM sound applications and for the experimenter, where conventional speakers and exciters cannot be used due to size constraints.
Another field of application for this transducer is 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.
A basic guide to creating invisible sound with exciters
Curious about how to create invisible sound with exciters? In this blog, Ben Zenker, an expert with more than 15 years of experience and 10 internationally reviewed publications, shares his in-depth knowledge on material selection, installation and optimising sound quality. An indispensable resource for the passionate DIY audio enthusiast.
An adhesive backed removable mounting pad is included with the BCT-3 to make it easy to remove the motor assembly if needed.
Note: The frequency response is given when used as a bone conducting transducer. This will change when attached to a substrate, and different substrate materials will have different frequency responses.
