The popularity of record players has waxed and waned over the years, but they remain a beloved part of music culture and have even seen a resurgence in recent times.
In this article, we will discuss how record players work, their importance and relevance in today’s world of digital audio, and some tips for maintaining them.
By understanding the inner workings of record players, you can begin to appreciate the history and nostalgia associated with them, as well as enjoy the unique sound quality that vinyl records offer. Let’s get started!
Components of a Record Player
A. Turntable
1. Purpose and Function
The turntable is the base of the record player, it contains a motor that rotates the platter, on which records are placed for playback.
As a result of this rotation, the needle/stylus follows a groove in the vinyl disc and produces sound waves in response to the vibrations.
2. Types of Turntables
There are two main types of turntables – direct-drive and belt-drive. Direct-drive turntables have a motor directly connected to the platter, allowing for more precise control over rotation speed and increased accuracy in reading the grooves, while belt-drive turntables use a rubber belt to connect the motor to the platter.
3. Platter and Mat
The platter is the surface on which a record rests during playback, and it can be made of different materials such as aluminium or acrylic. A mat, usually made of felt or rubber, is placed between the record and platter and helps keep the record in place during playback.
B. Tonearm
1. Purpose and Function
The tonearm is a curved arm attached to the turntable that holds the cartridge and stylus, allowing it to move across the surface of a record. As it moves, it tracks the grooves of the record and produces sound waves in response to the vibrations.
2. Types of Tonearms
There are two main types of tonearms – straight and s-shaped. Straight tonearms have a single pivot point and allow for easy tracking across the surface, while s-shaped tonearms provide more stability during playback by having multiple pivot points.
3. Counterweight and Tracking Force
A counterweight is used to balance the tonearm, allowing it to move freely without creating excessive pressure on the record’s grooves, while tracking force is the amount of pressure exerted by the stylus onto a record as it moves across its grooves.
C. Cartridge
1. Purpose and Function
The cartridge is a small device that holds the stylus, or needle, which is placed in contact with the vinyl disc during playback.
As it moves across the record’s grooves, it picks up vibrations and converts them into electrical signals, which are then amplified through an amplifier and speakers to produce sound.
2. Types of Cartridges
There are two main types of cartridges – moving magnet and moving coil. Moving magnet cartridges use a small electromagnetic field to convert vibrations into electrical signals, while moving coil cartridges use a tiny coil suspended in a magnetic field to do the same.
3. Stylus (Needle) and Cantilever
The stylus, or needle, is the part of the cartridge that actually touches the record. It’s usually made of diamond and is replaced periodically to prevent wear and damage.
The cantilever is a small arm supporting the stylus and allowing it to move freely across the surface of a record.
D. Amplifier and Speakers
1. Role in Producing Sound
The amplifier and speakers are responsible for amplifying the electrical signals from the cartridge and converting them into sound waves that we can hear.
The amplifier takes the low-level signal from the cartridge and increases its power, while the speakers convert these electrical signals into sound by vibrating membranes.
2. Types of Amplifiers and Speakers
There are many different types of amplifiers and speakers, including tube amplifiers, solid-state amplifiers, dynamic speakers, and electrostatic speakers.
Each type has its own advantages and drawbacks in terms of sound quality, power output, size, etc.
3. Other Components
In addition to the amplifier and speakers, there are other components involved in producing sound such as pre-amps, crossovers, power conditioners, and equalizers. These devices are used to control the signal from the cartridge and tweak it for optimal sound quality.
Record Anatomy and Function
A. Grooves and Modulations:
The grooves in a vinyl record are cut with a special stylus and form tiny ridges, known as modulations. These modulations are then read by the stylus as it moves across the surface of the record during playback, producing sound waves that can be heard through an amplifier and speakers.
B. Role in Creating Sound with a Record Player:
The grooves and modulations of a vinyl record are essential for creating sound with a record player.
As the stylus moves across the surface, it reads the ridges of the record, converting them into electrical signals which are then amplified by an amplifier and sent to speakers, producing sound.
The quality of the sound produced is dependent on the type of stylus used and the condition of the record itself. Additionally, factors such as counterweight and tracking force also play a role in determining the quality of playback.

Mechanics of Sound Production
A. Stylus Movement and Vibrations
The stylus, or needle, of a record player is placed in contact with the vinyl disc during playback and moves across its grooves as the record spins. As it does so, it picks up vibrations from the modulations on the surface which are then transferred to the cartridge.
B. Conversion of Vibrations to Electrical Signals
The vibrations picked up by the stylus are then converted into electrical signals by the cartridge, which is attached to the tonearm.
The cartridge uses either a moving magnet or a moving coil system to do this conversion, depending on its type.
C. Amplification and Conversion to Audible Sound
Once the electrical signals are produced by the cartridge, they are sent to an amplifier which increases their power. The amplified signal is then sent to speakers which convert it into sound waves that can be heard.
To ensure optimal sound quality, factors such as counterweight and tracking force should also be considered when playing a record.
Turntable Speed and Pitch
A. RPM and the three standard speeds
The number of revolutions per minute (RPM) is an important concept when it comes to playing records on a turntable. Most vinyl records are designed to be played at three main speeds – 33 1/3, 45, and 78 rpm – depending on their size, type, and age.
B. How to adjust the turntable’s speed
Adjusting the turntable’s speed is a relatively easy task that can be done with a few simple tools.
All you’ll need is a screwdriver, pliers, and some patience. Begin by loosening the screws on either side of the record disc until they are loose enough to turn with your fingers.
Then, adjust the speed dial to either 33 1/3, 45 or 78 rpm depending on the type of record being played. Lastly, re-tighten the screws and check for proper adjustment.
C. Effects of incorrect turntable speed
Playing a record at an incorrect speed can have a detrimental effect on the sound quality and may even damage the record. Playing at too high of a speed can cause distortion, while playing at too low of a speed can result in audio skipping or warping.
Additionally, incorrect speeds will affect the pitch of the music being played, making it either too slow or too fast. That is why it is important to ensure that the record player is set to the correct speed before starting playback.
Overall, understanding how a record player works and properly adjusting its speed are essential for producing high-quality sound. By following these steps, you can make sure your records are playing at their optimal speed and that you get the best audio experience possible.
