Product Details

Dayton Audio BCE-1 22 x 14mm Bone Conducting Exciter

Unlike conventional transducers that use moving air to produce sound around you, Dayton Audio BCEs (bone conducting exciters) convert the electrical signal into mechanical vibrations so clean, that the brain interprets the vibrating stimulus as excellent sound. Listener's ears are left free to remain aware of their surroundings, increasing personal safety.

When used against materials such as cardboard, wood, steel, and plastics, the BCE operates much like a surface exciter, capable of moving mass to produce robust sound output; much like an invisible speaker! BCEs are excellent for unique OEM sound applications and for the experimenter, where conventional speakers and exciters cannot be used due to size constraints.

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. Polarity is indicated by a small half-moon above the positive solder point.

Specifications: • Power handling: 1 watt RMS/2 watt max • Le: 0.56 mH • Impedance: 4 ohm • Re: 3.99 ohms • Frequency response: 300-19,000 Hz • Magnet weight: 49 oz. • Fs: 2,100 Hz • Dimensions (L x W x H): 0.85" x 0.57" x 0.31".

Dayton Audio BCE-1 22 x 14mm Bone Conducting Exciter
Dayton Audio BCE-1 22 x 14mm Bone Conducting Exciter is rated 4.0 out of 5 by 3.
Rated 5 out of 5 by from good little transducerI didn't realize how small this thing was lol. Sounds good. You will not hear bass thump but you'll hear great sound
Date published: 2014-11-21
Rated 2 out of 5 by from Limited usefulnessI purchased this exiter to vibrate powders and liquids and observe the resultant patterns created at different frequencies. Problem is the mounting screws that secure the vibration plate rise higher than the 1/4 inch plate itself making it difficult to mount a specimen dish without the screws totally damping the vibration. I have worked with the exiter and it functions as described. It's just hard to mount anything on it's plate.

Rated 5 out of 5 by from Great little deviceGreat sound quality, especially when pressed in the "sweet spot" somewhere behind the ear.

Dayton Audio BCE-1 22 x 14mm Bone Conducting Exciter

What's the best way to use this as a bone conducting exciter? Do you just have to hold it to your skull?

Asked by: K0balt

The conduction plate has two tapped holes on it. Can anyone tell me what size screw fits into them? A quick check with calipers shows an ID of 1.15mm so maybe M1.2? I don't know, the Dayton audio page describing the product is also lacking this info.

Asked by: Dteck
So nobody here at parts express could answer this. And I emailed Dayton Audio's support to try and get an answer. They never responded.... I took a shot in the dark and tweeted this question to their social media guys. It took a while but they did get back to me that the plates take 1.5mm screws. They didn't tell me the pitch but hey at least they responded.

The board I want to use with this puts out 10 watts per channel, much more than this requires, but it has a volume control. Is turning down the volume the same as limiting the wattage? If not what could I do to limit the wattage going to the exciter?

Asked by: JeffArd
Yes, you can use the volume control to limit the power going to the exciter.

Do they include mounting screws, data sheets mounting instructions?

Asked by: doug2
These do not include anything other than the exciter. The spec and recommended usage sheets are available for download on the product page.

How do you get it to work? Like wire it up to a mp3 player or something like that

Asked by: hahakbvjksvvsk
Bone conducting exciters often require more power to operate than a battery-powered portable device can provide. You should investigate a small audio amplifier to amplify the signal between your source device and the bone conducting exciter. The BCE-1 exciter can be connected to the amplifier speaker outputs, same as any other small speaker or exciter.

if i use two of this with a tang band wt 2040s 2 inch sub in a small enclosure, will it have some problems. suppose i separate the two sections?

Asked by: arjunm009
These transducers are designed to be mounted to a surface for very low volume sound reproduction. They would not be a good choice for an application like this.
