How do you stop a sound from playing when a tool is unequipped?

So basically I have this stretch of code here:

Saber = script.Parent.part

function onKeyPress(inputObject, gameProcessedEvent)
	if inputObject.KeyCode == Enum.KeyCode.Q then
	if Saber.ParticleEmitter1.Enabled == true then
		Saber.ParticleEmitter1.Enabled = false
		Saber.ParticleEmitter2.Enabled = false
		Saber.ParticleEmitter3.Enabled = false
		Saber.ParticleEmitter4.Enabled = false
		Saber.SurfaceLight.Enabled = false
		Saber.Off:Play()
	else
		Saber.ParticleEmitter1.Enabled = true
		Saber.ParticleEmitter2.Enabled = true
		Saber.ParticleEmitter3.Enabled = true
		Saber.ParticleEmitter4.Enabled = true
		Saber.SurfaceLight.Enabled = true	
		Saber.On:Play()
	end
end
end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)

function Off ()
Saber.Off:Play()
end

script.Parent.Unequipped:connect(Off)

Its a particle emitting light saber, and what its supposed to do is play an on/off sound whenever Q is hit, as Q is the on/off switched assigned, and turn the particles off. The code is almost perfect, however it still plays an on/off when you press Q even when the tool is unequipped/in your backpack. So basically I'm having trouble figuring out how to play the on/off sound when Q is hit ONLY if the tool is equipped.

If any one would be willing to help give me some advice or on what is wrong with the code, then I'll be happy to get that kind of response.

So you're saying the problem is the script is still listening even when it is equipped?

Add a conditional so the script won't fire unless it is equipped.

This can be achieved with the following:

if Saber.Parent.Parent == workspace and inputObject.KeyCode == Enum.KeyCode.Q then

Here's the modified code, except I made a table a for loop can run through.

Saber = script.Parent.part
local toggledProps = {Saber.ParticleEmitter1, Saber.ParticleEmitter2, Saber.ParticleEmitter3, Saber.ParticleEmitter4, Saber.SurfaceLight}

function onKeyPress(inputObject, gameProcessedEvent)
    if Saber.Parent.Parent == workspace and inputObject.KeyCode == Enum.KeyCode.Q then
        if Saber.ParticleEmitter1.Enabled == true then
            for a = 1, #toggledProps do
                toggledProps[a].Enabled = false
            end
            Saber.Off:Play()
        else
            for a = 1, #toggledProps do
                toggledProps[a].Enabled = true
            end   
            Saber.On:Play()
        end
    end
end

game:GetService("UserInputService").InputBegan:connect(onKeyPress)

script.Parent.Unequipped:connect(function()
    Saber.Off:Play()
end)
