These sound trees can produce atmospheric sounds such as birdsong, wind, or wildlife sounds, creating a relaxing environment, but they usually play rhythmic music.

A speaker works by converting electrical energy into acoustic vibrations (sound waves). The basic steps of a speaker are as follows:
Introduction of an electrical signal: An audio signal (alternating electrical current) from a source (such as an amplifier) is applied to a voice coil located in the speaker.
Interaction of the electrical signal with a magnetic field: The voice coil is in a constant magnetic field created by the speaker magnet. When an electrical current passes through the coil, it begins to move (according to the law of electromagnetic induction), causing mechanical movement.
Vibrations of the cone: A coil connected to the cone (membrane) transmits this movement to it. The cone vibrates, compressing and rarefying the air around it.
Creating sound waves: These mechanical vibrations of the cone result in the creation of sound waves that travel through the air and reach the listener's ear, turning into perceived sound.
The operating principle of a speaker can vary depending on the type of device:
Electrodynamic speakers use the interaction of a coil and a magnet to move the cone.
Electrostatic speakers work by changing the electric field between electrodes.
Piezoelectric speakers generate sound by changing the shape of the piezoelectric element under the influence of an electric current.
The purpose of speakers is to reproduce an audio signal for various purposes. Depending on the purpose, speakers can be used in different areas:
Home audio and video systems:
Used to play music, movies and other multimedia data.
Includes TV speakers, home theaters, and music centers.
Professional audio equipment:
Used for high-quality and powerful sound reproduction on stages, in recording studios, and at concerts.
Includes concert acoustic systems, studio monitors, microphones, and amplifiers.
Car speakers:
Designed to reproduce audio signals in a car, providing high-quality sound even in noisy conditions.
Portable speakers:
They are compact in size and battery-powered, making them convenient for use outdoors, while traveling, or relaxing.
Computer and multimedia speakers:
Used to reproduce sound on computers, laptops, game consoles, and other devices.
Alert and communication systems:
Installed in crowded places (airports, train stations, stadiums) to transmit voice messages and background music.
Used in security systems for emergency alerts.
Each speaker category is optimized for a specific application, where parameters such as sound quality, power, size and connection type are important.
Speakers (loudspeakers) are classified according to various criteria, such as the operating principle, purpose, frequency range, design features and materials used. Here are the main classifications:
Electrodynamic: the most common type of speaker. Sound is created by the movement of the diffuser under the influence of a magnetic field and alternating current in the voice coil.
Electrostatic: work by creating an electric field between two electrodes, which causes a thin diaphragm to vibrate, creating sound.
Piezoelectric: use a piezoelectric element that changes shape under the influence of electrical voltage, creating vibrations and sound.
Electromagnetic effect emitters: work based on a change in the magnetic field, which sets the diaphragm in motion.
Home speaker systems: used in home audio and video equipment.
Professional speakers: used in recording studios, concert venues and other professional applications that require high power and precision sound reproduction.
Car speakers: designed for use in cars.
Portable speakers: small in size and battery-powered, used for mobile devices.
Studio monitors: specialized speakers for precise sound reproduction in recording studios.
Low-frequency (subwoofers): reproduce bass and the lowest frequencies (20-200 Hz).
Mid-range speakers: designed to reproduce frequencies in the range from 200 Hz to 5 kHz.
High-frequency (tweeters): reproduce high frequencies, usually from 5 kHz and above.
Bandwidth speakers (full-range): capable of reproducing sound across the entire frequency range, although the quality at extreme frequencies may be worse compared to highly specialized speakers.
Cone speakers: the main part of the emitter is made in the form of a cone (diffuser). Most often used in low- and mid-range speakers.
Dome speakers: the diffuser has the shape of a dome and is usually used in high-frequency speakers.
Horn speakers: equipped with a horn that focuses and amplifies the sound, which increases the efficiency of radiation.
Flat speakers: use flat membranes that evenly radiate sound over large areas.
Open (without a case): the speaker works without a case, which leads to a large spread of sound in all directions.
Closed acoustic systems: the speaker is installed in a sealed case, which prevents the spread of sound from the back of the diffuser.
Bass-reflex acoustic systems: the speaker body has a special hole (bass reflex), which improves the reproduction of low frequencies.
Passive radiators: the speaker in combination with an additional element (passive radiator), which oscillates in time with the main emitter to improve bass.
Single-band: the speaker reproduces the entire audio frequency range.
Two-band: the system consists of two speakers (usually low-frequency and high-frequency).
Three-band: the system includes three speakers - low-frequency, mid-frequency and high-frequency, which allows for better reproduction of the entire frequency spectrum.
Active speakers: contain a built-in amplifier, which allows them to reproduce sound without additional equipment.
Passive speakers: require an external amplifier to operate.
These classifications help select speakers for different conditions of use depending on the requirements for sound quality, design features and connection types.
