Headphone / Speaker Toggle Switch

[bigfish313]

Does anyone know of an in-line toggle switch for the headphones?
I want a way to toggle between headphones and the external speaker.
I see the Grey Ghost headphones have a toggle switch build-in, but can't find out what it's for.

Thanks! HH

Most jacks in the detector have a switch built into the jack that disables the speaker when the headphone plug is pushed in.

GG switch is a compatibility switch to allow the headphone to be used on different machines with different headphone jacks and wiring.


Have not seen a device like you are looking for.

The only way to switch between the headphones and the sound coming from the detector is unplugging and plugging the headphones in. Like Jeff said, the switching of sound is built into the detector. The detector would have to be built with a switch. Any headphones you get would be unable to change this, since the headphone jack is built into the detector chip. The switch that is on the headphones you see is probably a on/off switch or volume, definitely not a toggle switch. I don't know of any metal detectors with headphone toggles.

Switches between stereo and mono.

Just out of curiosity, why are you wanting to go back and forth from speaker to HP's?

Google "Garrett Headphone Mod" The 5th or 6th result down will show a way to install a mini toggle switch in the earcup. It was really easy to do and worked well for me. if you flip the toggle back and forth it switches between speaker and phones. The real reason for this mod is because on the AT Pro the waterproof headphone cable is a real pain to unplug.

Beat me to the post.... Same on the CTX also when plugged into the m12 connector

1. I am making some videos for my Facebook people back in Michigan, I want them to hear the sounds. I can't stand using the external speaker and unplugging it all the time is a pita.

2. I am trying to train my 9 yo son how to metal detect and he has the attention span of a hummingbird. It's way better (for me) if I let him play with his friends then call them over when I get a bite. Last summer we had about ten 9 yo kids showing up at our play-dates. Everyone of them wanted to hear the sound.

Here are a couple of the videos... HH

Thank you! That is what I needed to know.
And this is what I did...

I think the only way to switch between headphones and the speaker is through unplugging the cable. I haven’t seen any toggle switch to change between both but it would be a good find if it’s true. I have got a good piece of in-ear headphone which I bought from a headphone dealer in Toronto and an even better speaker on my phone and I love to listen in both.

Did you watch the video? He already did it with a switch.

I don't understand how this could be achieved without going into the control box and rewiring the headphone jack. That would be simple, but the pics on the video are of the inside of the headphone earcup.
From my experience the speaker is physically disconnected from the circuit when the phone plug is inserted in the headphone jack...it's a lever that is pushed open by the headphone plug, opening the path to the speaker. As long as the phone plug is in the jack, there is no path to the speaker. It cannot be turned on.
Like I said, it would be simple to bypass this shutoff design, but you have to do it from inside the box. You can then mount a toggle switch anywhere on the housing, or you can run a wire to the headphones and put the switch there, but I don't see how it could be done without working in the box.
Maybe newer detectors use an updated system, perhaps being impedance-triggered, I dunno, but i'm only familiar with the traditional design.

That's not how it works on my AT Pro. There is no lever. When the jack is plugged in the current goes to the headphones. If the current is interrupted (toggle switch) it goes to the speaker.

Your thinking old school 1/4" audio eddie. The jack does not physically disconnect when inserted. That is also why the speaker on the AT Pro will still work at the same time with a pair of headphones connected that are not of the correct impedance. He simple used a switch in the headphone cup to disconnect the audio path which allows the speaker in the AT to work again.

 

[eddiecurrent]

I would like to know how it does that. yes, I'm thinking old school 1/4" phone plug, but whether its 1/4" or 3.5mm the method for re-directing the signal has been to physically interrupt the circuit at the jack. If anyone knows the theory I'd appreciate an explanation. Maybe I'll ask in the tech forum as well.

(On edit) I just realized we're talking about a specific detector here..the Garret AT pro, a dual use machine with the unusual feature (for water machines) of removeable headphones.
That explains the special design requirement of a different way to switch between internal and external sound.
I'd still be interested in knowing, from a technical perspective, how they designed it.

 

[stevieblunder]

I don't think we are only talking about the AT Pro. Most detectors are wired internally to accept the headphone loop first if it exists. If the headphones are unplugged it automatically switches over to the control box speaker. Take apart any headphone earcup on the cord side. Cut the correct wire in there and the machine will automatically switch to speaker even though the phones are still plugged in because the headphone complete loop is not there anymore. If you put a toggle switch in that cut line you are either completing the loop or interrupting the loop. This mod can be done on pretty much any machine with corded headphones.

 

[stevieblunder]

Also forgot to add this mod is normally done with the AT pro because it is such a hassle to unscrew the waterproof plug to activate the speaker. Even if you don't have that machine it's kinda cool just to reach up to your earcup, flip the switch, and show some bystander what you are hearing through your phones without having to unplug. HH

I have not found that to be the case on detectors (and stereos) i've worked on. The circuit is physically disconnected from the loop when the 1/4" jack is inserted.
Now there are many detectors, incl. the latest models, that I've never worked on, so I can only use my past experience as a guide.
I'd still be interested in knowing how the headphone loop replaces the path to the internal speaker. The only difference I can see is the impedance.

I really believe you are correct in saying it is the change in impedance that forces the machine to change between phones or speaker. Still the toggle switch mod changes the impedance by either completing the loop or interrupting it.
