It converts the electric energy into vibrations which are sound energy.
Electrical energy -> magnetic energy ---------> sound energy (signal) (electricity in voice coil) (sound waves)
One of the main kinds of speakers needs both. Sound in the form of varying electricity is fed through part of the speaker known as the 'voice coil' which is actually just an electromagnet. Since the electricity in it is varying the magnetism produced by this coil varies too. The voice coil is placed close to a permanent magnet and the voice coil is permitted to move back and forth in response to the electricity going through it. A big cone is fastened to the voice coil to transmit the movements of the voice coil to the air more efficiently. Thus overall the permanent magnet and the electromagnet work together to produce the sound waves that we hear from a speaker. For a more detailed explanation go to the How Stuff Works web site and search for speaker.
Lots of devices do that. A motor will convert electrical energy to mechanical energy (i.e., to movement); a lamp will convert it to light; a speaker will turn it to sound; etc.
Wattage is the power applied to a speaker. More power usually means more volume. The sound pressure that a speaker will produce will be defined by the power applied, the resistance or impedance of the speaker (a lower impedance speaker will be louder) and the sensitivity of the speaker as a whole (the efficiency to turn the power into sound).

The criteria for judging the question and answer portion typically include the clarity and relevance of the question, the depth and relevance of the answer provided, and the speaker's ability to articulate their thoughts coherently and convincingly. Judges may also assess the speaker's confidence, poise, and ability to handle impromptu questions effectively.

Because to drive a speaker you need to amplify the current from the microphone. The microphone alone will not generate enough electricity to move the speaker mechanisms.
There person listening is surrounded on all sides by speakers. The media is programmed to direct certain sounds through certain speakers.
speaker is an output device. It is said as an output device because, most of the speakers are used to hear audio/sounds. The inputs to hear sound from a speaker can be > power/electricity > a device to play the sound (that may be a mic, vcd, dvd, mp3 player or even your computer)
Electronic components used in speakers include capacitors, magnets, voice coils, an electrostatic speaker, and speaker wire. These components allow electricity to be converted into audible sound.
The rhetorical device that protects a claim from criticism by giving the speaker an out is called weaseling. Weaseling involves giving vague answers or adding qualifiers that suggest they may be wrong, which affords plausible deniability to the speaker.

The speaker is looking at a peaceful country scene, with rolling hills, green meadows, and maybe some grazing animals. She hears the gentle rustling of leaves in the breeze, chirping birds, and the distant sound of a babbling brook. Overall, she is surrounded by the soothing sounds of nature.
