The on-board speaker on a cell phone can only be so powerful, but external speakers can provide a much larger and fuller sound. Having the right external speaker to go along with a cell phone is a critical decision for any music lover, whether they're listening to tunes at home or taking the jam on the road. Many external speakers feature a standard 3.5mm stereo audio input jack; this can be used to connect the speakers to nearly all contemporary mobile phones the same way you would connect a set of headphones. This universal connectivity means that wired speakers will work with just about any mobile phone.

Speaker

Bigger Sound in Smaller Packages
Mobile
phones are fantastic convergence devices that have effectively combined the
functionality of so many separate devices, but their compact size has typically
limited both the volume and quality of the sound their speakers are able to
produce. Fortunately, many external speaker options are available, with
selections in all sizes and price ranges. A wired speaker may be the ideal
choice for you, or you may find that you prefer a wireless model or even a cell
phone dock. Whatever type of speaker you choose, you're sure to enjoy the
larger sound.
If you enjoy listening to music at the beach, by the pool or even in the shower, a waterproof speaker is a must-have tech accessory.

Waterproof speakers will work with most Android and iPhone smartphone models.

Great Music Without Water Worries
Any of these speakers make it easy to enjoy
your favorite tunes while engaging in outdoor activities - and these are just a
few of the many available options. Don't let a little water keep you from
listening to the sounds you love while getting outdoors and staying active,
even if your choice of activities takes you near - or even on - the water.
Chose the model that best meets your needs and you'll be on your way to many
moments of outdoor listening enjoyment.
Sound waves travel through air pressure changes, and the sounds you hear differ depending on how frequent and how big those waves are. Microphones turn sound waves into electric signals, which is how you can record sound onto CDs and other devices. When you play the recorded sound, it's turned back into an electrical current. Speakers work like reverse microphones. They turn the electrical currents into physical vibrations that make the sound waves for your ears to pick up. When everything is tuned properly, the speaker is able to reproduce the vibrations that the original microphone recorded and changed into electrical signals.
The voice coil component of a speaker is actually just an
electromagnet. Electromagnets are coils of wire, and they're normally wrapped
around some kind of magnetic metal, like iron. By running an electrical current
through the wire, you produce a magnetic field surrounding the coil; this field
magnetizes the metal in the middle creating north and south polar orientations.
The difference between an electromagnet and a permanent magnet is that you can
switch the polar orientations on an electromagnet by reversing the current's
flow.
Stereos use this property of electromagnets to
repeatedly reverse the electrical flow. The amplifier switches the signal over
and over, making the red output wire on the stereo switch between positive and
negative charges. The voice coil's electromagnet is placed within a permanent
magnetic field. The two magnets interact, and every time the electromagnet's
polarity changes, the interaction between the magnets changes. When the magnets
are repeatedly repelled and attracted, they move the coil back and forth
quickly, kind of like the piston in an engine. The moving coil presses and
pulls on the speaker cone and vibrates the air in front of the speaker. This
creates sound waves via a driver that vibrates the diaphragm.
