LG has developed removable acoustic transducers that will be able to perform different functions in different modes – whenever hooked to a cellphone, it acts as traditional speakers and a microphone, but when you remove them, the transducers end up as wireless earphones.
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.
There isn’t further elaboration on LG’s part, and I wonder when will such technology be implemented. As with anything new, sooner is always better – just keep the price point low/affordable.
