Reduce rumble vibration

[Erwin Ried]

I have a little wireless keyboard that I use with a raspberry pi, the keyboard is nice but it has an annoying noisy vibration.

How to reduce that vibration? simple resistor should work?

    What are you reffering to ? A mechanical vibration ? I don't understand... Please explain...

[Erwin Ried]

Yes, sorry a tiny small motor with a weight, but it rumbles too strong

[valentinc]

     The motor is inside the keyboard as feedback when you press a key ? Or commanded by the raspberry pi ?

     If the power consumption of the motor is not high (and I guess it shouldn't be if it's one like those used in mobile phone) a simple series resistor will work...

[Erwin Ried]

Yeah it is a small mobile vibration motor. I will try with a resistor

What type model maker is it.

I can imagine, to save batteries, there is an option to switch it off

You could just disconnect it if you don't want it on at all, or measure the current/voltage it uses with a multimeter and find the resistor you would need o reduce it by half.

Almost all the reviews in different places tell about the annoying vibration. It is useful, but it is so strong! It was pretty easy to disassemble but there was an extra screw below the acrylic surface, so it is impossible to do without denting the plastic. I also broke the small smd switch used to switch mouse/keyboard, but I had a similar switch (a bit higher, but solved cutting part of the plastic button).

Tested some resistors and a 100 ohm one leaves the device with a smooth almost invisible rumble, perfect as tactic feedback.
