The seam on walking belt is coming apart.

a small 1/2 inch wide piece of tape around the male piece 1 1/2 wraps. black or duct tape.

Forget fixing.

Try applying a quantity of blu-tack to get a hold on the battery. If you're not bothered about the battery, epoxy glue something you can hold of on (leave to set) and you should have good purchase on the battery. Hope this helps.

first,i never seen uc 280 speakers & dont know if it is a wood or a plastic speaker enclousure. 1. try looking 4 screws again, you might have missed them 2. if you sure there are no screws,you may have a plastic speaker box that was put together with crazy glue. in that case you will have to look for seams to crack or pry with two large flat bladed screwdriver or two very stiff puddy knifes. if you cant find a seam good enough to get a screwdriver into to start the pry job, you will have to take a stiff thin bladed knife that you dont mind ruining the looks of and heat the blade
red with a propsine tourch $12.00athome depot or a gas stove
burner will do & saves you $12.00. even an electric stove burner might work if you put the knife blade on the burner & a heavy black cast iron fry pan in the top of the knife blade.
anyway,one you get the knife blade or flat screwdriver tip hot,you can ment a slot through the plastic enough to get a pry started.
by now you realize that we are going to make somewhat of a mess of your speaker box, but if it is crazy glued together,this is all that can be done about getting it apart.right now,you dont have a working speaker. you may end up with a working speaker that looks like it survived world war 3 in bad shape, but best I can do,so sorry.if you can pry it appart enough to get inside and reconnect the wire, the test to make sure speaker does work,we ate ready to glue it back together. A hot melt glue gun from you local dollar tree or dollar store will do the trick or a tube of crazy glue.alternately,you can use the engineering llc solution
which is ,if its susposed to move and dont, use wd40 but if its not susposed to move but does,use duct tape.
so you can use a good grade of duct tape to hold your speaker box together with,if need be.

in the past,we have used hot melt glue gun to reattach the plastic front of a vw passat so it would be flush with the front fenders when a sheet metal screw didnt work good. used the hot melt to keep the sheet metal screw from coming out and to hold the edge of the plastic in flush to the fender edge. god help who ever takes that apart again. hope he is a good problem solver because that vw solution was from mickey mouse enginenering, llc

Your best bet is 30 min epoxy. As it will harden very stiff and seal the sound in well. Super glue may also work just as well but i think it will dry to quick.

Most home improvement stores will sell in the small 2 part tube. Which when mixed can be applied to stuff.

super glue, duct tape?

a picture would be worth a thousand words here

you should have some electronics experience before attempting a repair like this
rip off the black rubber back
if yours has screw righty tighty lefty loosey
if not cram a small screwdriver in very very carefully and break the back off without injuring yourself
than locate battery pack [looks like watch batteries
unsolder/UN-clip
take battery pack to radio shack [might as well get good ones]
now do the above steps backwards
super glue or black electrical tape [i used that]
or if you really want to impress gray duct tape maybe you could even bedazzle the project?
really its a throw away product i got out the magnifying glass and read the very not-so helpful owners manual that came with my Sansa view
hope this helps please vote

Be extremely careful when trying to trim a belt. Understand that many hazards exist when performing these steps that can result in serious injury. If you have any question whether you can perform these steps or not, please call a professional and do NOT attempt this repair.
There are two methods that can be used to trim a walking belt when it has developed a tattered edge:
1) Remove the belt from the treadmill for trimming.
a) All walking belts are cut at some point during their life, whether in manufacturing or later during service, so this will not compromise the integrity of the belt as long as you cut a straight line and do not leave a rough edge.
b) Remove the walking belt from the treadmill, lay the belt flat and even on the ground, and measure and equal distance on each end of the belt and mark the belt for cutting on each end of the belt. Cut no more than necessary to restore a smooth edge.
c) Use a piece of flat steel or other metal object that is straight and long enough and connect the two markings on the belt with the metal object.
d) Using a new razor knife, box knife, or similar instrument, cut the belt along the steel object. If the knife has a new edge, you should cut through the belt in one or two passes of the knife.
e) Check the belt for a smooth edge and reinstall the belt.

2) Cut the belt while it is mounted on the treadmill. This method should only be considered by those who are familiar with treadmills and very good with tools. This can be a dangerous process.
a) Track or center the belt off center to the opposite side of the tattered edge (i.e.- if the belt is tattered on the right side, track the belt off centered to the left side by about 1/2 to 3/4").
b) Operate the treadmill at a very slow speed. Usually 1.0 or 1.5 MPH will be sufficient.
c) Using both hands, line a new razor knife up on the tattered side of the belt. Make sure to cut no more than necessary to make a smooth edge.
d) With the belt moving and using both hands, lift the knife up and contact the belt making sure to hold the knife steady and keeping your hands and clothing as free from the moving roller as possible. You will not damage the roller to the point where it will hurt the operation of the treadmill.
e) Do not lower the knife until you see the belt separate from the tattered edge. Once this happens, turn the treadmill off, unplug the treadmill, and cut the tattered strip off the treadmill.
f) Track or center the belt and operate normally.

Everything is repairable! Between epoxy, super glue, model glue (works better on the plastics it's designed for) and Duct Tape!?!? Yankee Engineering!!, Come on. :^D

But to answer your question: eBay

yes u can just super glue it.
