The primary objective of speakers is to offer audio output for the listener. The electromagnetic waves are converted into sound waves through the speaker as they are transducers. The devices, like an audio receiver or computer, give audio input to speakers, which may be in the form of analog or digital.

What is the function of speakers in computer?
A computer speaker is an output hardware device that connects to a computer to generate sound. The signal used to produce the sound that comes from a computer speaker is created by the computer's sound card.
How does the speaker work?
Speakers work by converting electrical energy into mechanical energy (motion). The mechanical energy compresses air and converts the motion into sound energy or sound pressure level (SPL). When an electric current is sent through a coil of wire, it induces a magnetic field.
What is a loudspeaker and what is its purpose?
loudspeaker, also called speaker, in sound reproduction, device for converting electrical energy into acoustical signal energy that is radiated into a room or open air.
What is a speaker simple definition?
Speaker is defined as an electrical device used to make sound or music louder. An example of speaker is how music is listened to in a car. ... The definition of a speaker is a spokesperson or a person giving a speech. An example of speaker is the person who people have gathered around to hear talk about something.
Why speaker is an output device?
Speakers receive information from computers (think smartphones, laptops, tablets, etc.) and are, therefore, output devices. This information is in the form of digital audio. As we've discussed, the digital audio must pass through a DAC before it is able to drive the speakers to produce sound.
Where are speakers used?
Loudspeakers are used in radios, audio players, Bluetooth speakers as well as many other areas. Loudspeakers have been used for many years to convert electrical signals into audio sound waves.
What is inside a speaker?
Also known as the “tweeter”, “woofer” & “mid-range”, every speaker uses a different configuration of drivers. Whether a woofer or a tweeter, all drivers comprise of an electromagnetic voice coil, a stationary magnet and a diaphragm. ... The coil needs to be free to move in and out of the magnet gap, but not side to side.
How does a speaker make sound?
The center of the speaker cone is attached to one end, which gets driven back and forth by the moving coil. This cone is held at its edges by an airtight suspension or surround. As the cone moves, it pushes and pulls the surrounding air; by doing so it creates pressure waves in the air, called sound.
What is the difference between a speaker and a loudspeaker?
Senior Member. Loudspeaker is any device that magnifies sound so it can be heard (it can even refer to a megaphone, you know, that cone-shaped hand-held device people address crowds with). Speaker is usually what the sound actually comes out of (these are often covered with cloth-like or metal mesh).
Why do speakers have magnets?
Answer: Every amplifier (speaker) has an electrical current. When the current is changing, it produces a magnetic field. To make the cone (or panel) of the speaker move, magnets are used to create an opposing magnetic field which creates vibrations. These vibrations are the sound we hear.
What is speaker communication?
Key Points. Speech communication, in its simplest form, consists of a sender, a message and a recipient. The speaker and sender are synonymous. The speaker is the initiator of communication. Effective speakers are those who can most clearly delivery their message to their recipients.
What means speaker out?
Only show this user. Originally Posted by xenophobe. Line out is an unpowered line-level signal, meaning it does not contain extra power to run speakers. Speaker-out has power, and generally can adjust the volume with software, like inside windows.
What type of device is speaker?
Printers and speakers are examples of computer output devices. Printers output digital information such as text or image files to a physical medium such as paper. Speakers output the audio from digital files into audible sound waves.
What are analog speakers?
Analog audio consists of a continuous signal with varying voltages that represents sound, directly from the source. The vibrations produced to create those sounds are precisely what is recorded. That may include some noise and echo as well, but that can be eliminated by signal conditioning equipment.
