No, the sound card is attached to the motherboard of the computer.
The speaker is still attached via a cord it can be positioned for optimum sound
speakers
Speakers are attached to computers for the output of sound. Sound cards are required in the computer for speakers to function. Speakers range from simple; two-speaker output devices to surround-sound and multichannel units.
Sound is generated from a speaker through the vibrations of an electromagnet attached to a diaphragm. The electrical signal from an audio source causes the diaphragm to move back and forth, creating sound waves that travel through the air and are heard as sound.
How about this: What's inside the box? How Sound Wave Intensity changes in a speaker box to outside.
A microphone connected to an amplifier and speaker(s).
Magnets are used in speakers because they play a crucial role in converting electrical signals into sound waves. Inside a speaker, the magnet interacts with a coil of wire attached to a diaphragm, causing the diaphragm to vibrate and produce sound. This vibration creates the audio waves that we hear as music or speech. In essence, magnets help to create the movement needed for sound production in a speaker system.
Internal speakers are speakers that are mounted inside electronic items such as computers or radios. Unlike an iPod, which requires headphones plugged in, equipment with internal speakers do not require headphones or other speakers to be plugged in.
Electric current from the sound card is applied to an electromagnet changing magnetic field pushes a magnet back and forth,which is attached to the speaker cone.The moving speaker cone creates changes in the air pressure which your brain interprets as sound.
The electromagnet in a speaker creates a magnetic field that interacts with the permanent magnet attached to the speaker cone, causing it to move back and forth rapidly. This movement generates sound waves by creating vibrations in the air, which we hear as sound.
Sound eXchange is a piece of software which allows you to manipulate files. The decibels produced by the program are only limited by the speakers you have attached to your computer.
I have Dell's computer and for sound i am using the Liztek's Bluetooth Speakers which is very good to use and the best thing of this speaker is that there's no hassle of wiring because they are wireless.
