dig up an archive plan of one from the 1900s to treat "hysteria" in women. The ones I see are pretty much a Milwaukee impact driver attached to an "end effector". Should be significant enough for anybody. On the subject of concrete vibration, It looks like exactly what you're looking for, but size wise maybe not. https://www.contractorsdirect.com/M-2500-Internal-Vibrator-Kit This one is 2.5hp and I think that might be way above what you're looking for, but its expensive. You could probably rent one from home depot and see. If nothing else you can get you're hands on it to see how its put together to figure out how to do you're own. Or you find out its just what you're looking for and you have a model number to order. Either way.

 

One more time: A product for a similar application is made by "Hitachi" and marketed for the purpose described. A web search should bring up distributors.

I am totally aware. I get asked to repair some very unusual "toys" for some folks. I am also aware of exactly what the "Hitachi" is used for, aside from sore muscles.

Ok. I was trying to be discrete but my wife has a condition that makes it difficult to “o”.
It takes something very powerful to work.

I don't think he wants to jackhammer his wife's private parts. The purpose intended is for personal pleasure in that very private place a woman has.

 

I googled around and 'linear resonant actuators'. Looks like haptic feedback. Not sure its strong enough.
Have you tried just a solenoid with a captive rod? Might be powerful enough. Could use a function generator to mess around with the frequency of the ac signal you feed into the solenoid. See what works best with it.
Like THIS one on amazon. Its a bit bigger than your 1" but its a place to start.

 

@jiggermole; this is for a sexual device. Delicacy is the important part. You don't want something that can smash tin into thin sheets. Think of what that would do to tender sensitive flesh.

We all need to keep in mind the TS is looking to build his own tool. We need to be delicate in our comments and be practical in offering solutions. Until we knew the exact purpose of this thread we were off on things like cement vibrators and such. The TS wife isn't going to want some industrial earthquake machine between her legs. And that is as personal as I'll get on the matter. Again, delicacy is the key to this thread. Both in comment and in application.

 

There are massage vibrators out there which offer more serious vibe than the typical adult toy store variety. Find a good one and modify it.

You're insistence on gentility shows you haven't been around the internet much. No I was thinking more of the motive solenoid being on the opposite side of the business end. Something you can attach to an existing device. Or you can seal the solenoid in a can like a film canister or something and then embed it in a custom silicone form. Then all you'd have exposed is your power leads. However you plan on doing that. You can buy molds and I think most of the two part silicone is body safe, you may have to look at the mix. The molds might require some digging, or make your own with some plaster of paris maybe. Most of the devices you find use like a haptic motor and are tiny. I figured with a solenoid, it would provide more power and the snap at the end of the solenoid stroke, i thought, might me an interesting change in feel.

Nope! Don't do sex toys or porn.

 

I DID get asked to repair "toys" a couple of times, each time the problem was broken wires in the rather fragile power cords.. I have never seen or been asked to repair any "toy" with a solenoid type of mechanism.
The device referenced as a "Hitachi" is also marketed as a muscle massage appliance, not a sex toy. It has a larger diameter motor and a shaft extension with an unbalanced mass on the shaft. That part was enclosed in a stamped stainless steel housing, not quite spherical. Loose screws and knotted power cords are the damage those toys suffer from.They get repaired instead of replaced because they are far from inexpensive.

 

I was just going off the OPs statement that it needed to be more substantial than a regular one. My brain went for industrial vibratory setups and solenoids as the step up from regular devices. MisterBill, I think the Hitachi one you mentioned may be a good step between industrial level stress relief and normal use. And if it fits the strength and not the form than reconfiguring is still an option. Just double check the silicone is body safe if they do go to make their own.
From my own experience. If you go the route of 3d printing something, be very very sure of the print. I printed in ABS and had to go all the way up to 60% infill before I was satisfied it wouldn't break. Then I treated it with acetone to get the layer lines stronger yet, and smooth. Then destructive testing before making a final one for use. I figured if it could take a static load of 400lbs and also take a good whack with a hammer than normal use wouldn't do any damage to it.

Lots of "Muscle Massage appliances" have been used for self pleasure. Oster makes one with springs you wrap around the palm of your hand. It vibrates like crazy. Here's one for $129.87. Bit pricy but its advantage is one could use it personally or it could be used by a partner. With the sensitivity of fingertips one could modulate just how much stimuli is being introduced to that sweet little spot.

My brain went for industrial vibratory setups

I think most of us went there with "industrial strength" being the focus until the TS made it clear it was being used for Other purposes. Which is fine.

 

Motors between 1.5 inches and 2 inches diameter are used in all kinds of vibrating furniture attachments, Exactly identical scheme, jus a bit too large. BUT it verifies the concept.
Probably slot-car motors would be a suitable size. They should be available in many parts of the world. And not even known to exist, in some other parts of the world.

 

If this doesn't do the trick?!
