Whether music, games, movies or a small video in between, whether Skype conversations with friends or family or business video conference, no sound is no computer today and no laptop, tablet and smartphone more. However, the built-in speakers, if present, often do not provide the desired sound or volume. However, PC speakers that can be connected not only to the computer but also to many other playback devices provide good sound throughout the room, or in the case of portable, battery-powered devices even outdoors.
Top 10 PC Speakers
What are PC speakers needed for?
Whether desktop PC, laptop or netbook, tablet PC or smartphone, computers are now part of everyday life and are often used in multimedia. Of course, it depends on the right sound and the PC speakers come into play here. The small speakers are very versatile and not only suitable for the PC. They can be connected to many different playback devices and provide a rich sound that the playback device itself cannot afford in most cases. For example, you can connect the speaker boxes to
- Desktop PCs on the desk
- Laptops, notebooks or netbooks
- mobile devices such as smartphones or tablet PCs
- MP3 player
- Language assistants like Echo Dot
There are usually two reasons to use PC speakers:
- The device itself is not equipped with speakers
- The player has an internal speaker that does not provide the desired sound and/or volume
Desktop PCs, which are usually equipped with a sound card but do not have their own internal speakers, fall into the first category. To enable sound at all, speakers must be connected to the PC.
The second category includes many other devices such as smartphones, tablet PCs, laptops and notebooks, TV sets or MP3 players. These devices usually have an internal speaker or, in the case of MP3 players, a headphone jack. However, the existing speakers in many cases do not provide the desired sound or volume level, so additional external computer speakers are connected. With good PC speakers, the home computer quickly replaces the old stereo and even the smartphone or the MP3 player are quite well suited to fill a whole room with music with good sound. Games or movies on the PC, The PC speakers give the tablet or laptop a whole new sound quality and the sound does not crawl even in fast and loud action scenes. The same applies to televisions, which today often offer a good picture, but often also disappointing sound qualities. Especially with a bit louder scenes, it quickly happens that the bad sound spoils the movie pleasure. However, with the right connections, PC speakers can be easily connected to the TV, and the stereo speakers make the sound even more realistic. that the bad sound spoils the movie pleasure.

How do PC speakers work?
Knowing which features make a good PC speaker and what to look for when buying PC speakers is not a bad thing for knowing how the PC speakers work. The way they work does not differ fundamentally from other speakers, so here. we take a look at the inner workings and functioning of loudspeakers.
As a rule, all loudspeakers consist of these components:
- Do the washing up
- permanent magnets
In the center of the speaker is at least one coil. It consists of a wound wire through which current pulses flow. These current pulses, which constantly change direction, are sent from the connected playback device, which converts the stored sound recordings into current pulses.
Within the wound coil, the individual turns are isolated from each other, so that the current can not skip, but must run through all the turns. This creates an electromagnetic field in the interior of the loudspeaker that, just like the current pulses, changes direction over and over again. Other magnetic fields are generated by the permanent magnets in the speaker, which are located at both ends of the coil. There are always two permanent magnets per coil in the loudspeaker. The inner permanent magnet with the north pole points towards the coil, while the outside magnet with the south pole points towards the coil. Unlike the coil, the magnets do not require electrical current to build up a magnetic field, and the various magnetic fields apply a force to each other that causes the coil to reciprocate. This is done in time with the current pulses and thereby the membrane, which usually consists of a thin film or special cardboard, and which is fixed depending on the design of the speaker to the coil or the permanent magnet, also vibrated. These vibrations are transmitted to the air, which, depending on whether the membrane swings forward or retracts, is compressed or diluted and in this way, sound waves are generated. If these sound waves reach the ears, they are transformed into sounds. These vibrations are transmitted to the air, which, depending on whether the membrane swings forward or retracts, is compressed or diluted and in this way, sound waves are generated.

If these sound waves reach the ears, they are transformed into sounds.
A lateral displacement of the speaker diaphragm is prevented by the so-called spider, a kind of spring, and a flexible edge suspension, the so-called bead. So the membrane always springs back to its original position.
The history of the speaker
The first electrodynamic loudspeaker was patented in 1874 by the German industrialist and inventor Ernst Werner von Siemens. Even with this speaker, a diaphragm was moved through a copper coil. Already a few years earlier, in 1861, the German teacher Philipp Reis had developed a loudspeaker in connection with the telephone invented by him, which also consisted of copper wire, which was wound around a knitting needle and vibrated instead of a membrane a wooden box. The first sentences spoken by this speaker included the sentences “The horse does not eat cucumber salad” and “The sun is from copper”. These unusual sentences had been specially chosen by Reis to prevent
Due to the not yet mature construction of the speaker, the sentences sounded very distorted and quiet, but the transmission worked. Rice, however, died young and could claim neither the invention of the phone nor the invention of the speaker.
The electrodynamic loudspeaker patented by Ernst Werner von Siemens was further developed and improved in the following years by various inventors and finally, in 1925 the Americans Chester Rice and Edward Kellogg developed the electrodynamic loudspeaker as we know it today.
There are these types of PC speakers
The electrodynamic loudspeaker is not even 100 years old, but a lot has happened during this time. So today there are many different forms of speakers for different purposes. Also with the PC loudspeakers, there are different kinds, which we want to throw a closer look here,
Anyone who thinks of the loudspeaker boxes of a hi-fi system or a home theater system certainly thinks of the amplifier in this context. This amplifier is used to amplify the electrical signals from the sound source and forward it to the speakers. If you were to connect the loudspeakers connected to the amplifier, which are called passive loudspeakers, to a sound source directly and without the amplifier being connected, they would not produce any sound. But how can the PC speakers do without such an amplifier? The answer is simple, as PC speakers are usually active speakers. They have a built-in amplifier and can be connected directly to a sound source and play sound. However, unlike the passive speakers, you will need a power source, because, without power, the integrated amplifier cannot work. The PC speakers are therefore either connected to a power outlet with a power cord or they receive their power via a USB cable directly from the connected playback device. In some cases, there is also a built-in rechargeable battery that charges from the power source, or the boxes can be powered by batteries. This makes the speakers for the PC or other multimedia devices even more flexible and can, for example, be taken outdoors.

This makes the speakers for the PC or other multimedia devices even more flexible and can, for example, be taken outdoors.
But not all PC speaker boxes are active speakers, because it is differentiated between different types of speakers such as a soundbar or speaker systems 2.0 or 2.1.
The term soundbar refers to a long and narrow speaker that creates a spatial sound experience even without the use of multiple speakers. Soundbars are especially often combined with a TV because they take up little space and provide a good home theater sound. Soundbars are also offered in the area of PC speakers, but they are much smaller. These are active speakers, which are equipped with an integrated amplifier and usually with two midranges and a subwoofer. The soundbars create a good surround sound with a single device and they are usually equipped with a battery or can be operated with batteries, which makes them particularly mobile.
2.0 speaker system
The 2.0 speaker system is the classic speaker system for the computer. It consists of two loudspeakers connected by a cable. One of the speakers also has a power connector and connectivity to a playback device such as the computer. This loudspeaker is an active box, while the second loudspeaker is a passive box that does not have an integrated amplifier. In the active box is the built-in amplifier, which transmits its signals to both speakers.
5.1 and 7.1 speaker systems
To create a true surround sound, there are also 5.1, 7.1 and even 9.1 speaker systems. However, they are primarily used in home theater systems or hi-fi systems and play no role in the field of PC speakers.
The different connections
The PC speakers presented here are invariably wired, so it is, of course, important that the connections of speakers and sound source match each other. There are different connection types for the audio signal and the power supply.
Connections for transmitting the audio signal
Jack, jack plug
With a jack or jack is in connection with the PC speaker usually meant a 3.5-millimeter jack. Most sound cards, and thus the desktop PC or laptop, have inputs and outputs for a 3.5-millimeter jack and so many PC speakers are equipped with such a plug. To connect the PC speakers with a smartphone or a tablet PC, however, is often a 2.5-millimeter jack necessary. Commercially available adapters are available.
An AUX connection offers the possibility to connect further devices. A jack or RCA cable can be used to connect many other playback devices via the AUX port.
The cinch cable is considered the classic audio connection. With it, for example, the TV set can be connected to the PC speakers.
Connections to the power supply
A USB plug on the PC speakers is usually the power supply of the active speakers. The advantage of a USB connection to the power supply is that no extra power outlet is needed.
The PC boxes can also be supplied with power via a conventional mains plug. This variant is well suited for PC speakers that have their fixed place on the desk and the USB ports remain free for other devices.
A lot of watts, a lot of good?
Many questions surround the purchase of loudspeakers with the right wattage and the PC speakers are no exception. But does high wattage automatically mean that it’s a good speaker that delivers high-quality sound? At least this question can be answered easily, with a clear no. The wattage indicates the power of the speakers, which is not decisive for the quality of the reproduced sound. For example, a PC speaker with a high wattage may sound distorted and unnatural.
The wattage says something about how high the electrical power that is supplied to the speaker through the amplifier. So here’s more on the relationship between speakers and amplifiers, on which one has no influence anyway with active speakers with built-in amplifier.
Why are the PC speakers rushing?
If you find that your PC speakers are rushing, this can have different causes. For example, a faulty cable or cable that is not connected correctly may cause the noise. Check all cables and connections. Another cause of speaker noise may be incorrect volume control. To set the volume correctly, follow these steps:
- Turn the volume on the PC speakers to zero
- Now set the volume on the playback device to about 75%
- Start playback and slowly increase the volume of the speakers until you reach the desired volume
If the noise can not be removed by these measures, check if the noise is not already in the recording.
Why does crackling and crackling in the PC speakers?
In addition to noise, PC speakers can often cause noise when a smartphone or other device emitting radio signals is too close to the speakers. The best way to avoid this is to slightly increase the distance between the interfering devices and the speakers. Often there are already 20 or 30 cm sufficient.
How should the speakers be positioned?
The correct position of the speakers has a great influence on the quality of the sound.
- A soundbar should be placed as centered as possible, as it performs the same task as two individual speakers.
- The two speakers of a 2.0 system are best placed on the left and right of the computer screen. Since a 2.0 system is usually an active box and a passive box, the active box with the connectors should be the one closer to the computer.
- For a 2.1 system, you should also place the speakers to the left and right of the screen. There is no explicit rule for the position of the subwoofer. Often it is placed in the middle, for example under the desk, but it can certainly find a place in a corner. Here it does not hurt to try out different locations and to rely on the ear when positioning.
Maintenance, care, and disposal of PC speakers
Special maintenance or care is not necessary for PC speakers. They should only be wiped regularly with a soft cloth and protected from excessive sunlight. The speakers require slightly more care if the housing is made of real wood. They should be maintained according to the specifications of the manufacturer. You should generally refrain from using water or cleaning agents when cleaning PC speakers. Small spaces can be cleaned well with a soft brush of dust and dirt.
