Help identifying a part....

Hi I have an android speaker like this **broken link removed** but an "x" part is broken, I know which but I don't know how it's called so please somebody help me identifying the part name so I can buy it and replace the broken... In the back of the board it writes a number (see in photo), Here's the photo:View attachment 60700View attachment 60701

I think it is a potentiometer but does it have a specific name or how do I search for it???

if it is making stepping clicks at 12 or 16 steps per rotation, it could be a rotary encoder.
otherwise it is a resistive potentiometer. once the rotation is found smooth you can find out the total value of the pot , by measuring resistance across outer pins .
then wrt to one side , you could measure with one end of rotation indicating full value as measured earlier. now,rotate by 1/3rd of the 300 odd degrees possible, measure. then rotate another 1/3rd, if the measurements are proportionate approximately, then it is linear one, otherwise logarithmic one. in general volume controls that manage audio are logarithmic.
ps:
a rotary encoder rotates continuously with no end stops .

Now it is broken and it rotates continuously but before it rotated about 30degree and it gets back...sorry I don't know how to explain it so better look at this video how it worked (look the android head)... https://www.youtube.com/watch?v=bb_HUwQ_nwI&feature=related

I think it looks like this: https://www.electro-tech-online.com/custompdfs/2012/02/pec11l.pdf

Looks like a rotory switch to me but may be an encoder.

i should be a rotary encoder your photograph shows that in addition to body pins , the device has 3+2 five pins in all
thus it has also a push to switch facility
and surely it is rotary encoder.

Thank you all, yes it is rotary encoder
