Removable speakers/earphones for your mobile from LG

With Bluetooth headsets gaining in popularity everyday, cellphone vendors are trying to think of new ways to make them even more comfortable to use. We’ve seen one such interesting attempt from Samsung – with removable Bluetooth headset attached to the phone.

Now it’s LG’s turn to reveal something cool in headsets. And they have come up with removable acoustic transducers.


The basic idea is that these detachable acoustic transducers are configured to perform different functions in different modes.

When  attached to the phone, they act as traditional speakers and microphone. Their batteries are charged there as well.

Transducers then become wireless earphones, when you pop them out of the phone and put them into your ears.

When receiving or making a call, one of them is prompted to become a wireless microphone and the other stays in earphone mode.

The transducers can selectively implement one of a speaker for emanating a sound and a microphone for converting sound waves into electrical signals. For example, the microphone senses small vibrations of the user’s vocal cords when generated through a vibration plate, amplifies them and converts them into electrical signals, and the speaker emanates the sound of the signals from the vibration plate.

LG is rather vague about it, but it seems that you don’t even have to take the thing (in microphone mode) out of your ear, to transmit voice. How this is implemented I have no idea, but I guess it’s doable. You can hear your own voice, afterall, so why can’t this fancy transducer in your ear detect it too?

And it gets better. LG says that you’ll be able to keep one of transducers in earphone mode listening to music/radio in the right ear, while talking on your phone via the other transducer in the left.

You know, for some serious multitasking and continuous partial attention training perhaps…

    I like parts of the idea. Always charged head phones would be great. Even better if there is no need to keep a wire between them – totally wireless stereo. Two concerns, I usually keep on in my ear for lengths of time – perhaps it would be a good idea to enable usage with only one earphone at a time, so that one can always be charging. Second, hopefully they have a loudness limit on the units while in the ear as I expect them to be quite loud to function as speakers.
