Professional audio generally refers to the audio used in professional entertainment venues such as dance halls, KTV rooms, theaters, conference rooms and stadiums. Professional speakers own high sensitivity,high sound pressure, good intensity, and large receiving power. So, what are the components of professional speaker equipment?

The structure of professional speakers: professional audio equipment consists of monitor mixer; power amplifier mixer; portable mixer; power expander; dynamic microphone; condenser microphone; wireless microphone; speaker; monitor speaker; power amplifier speaker; ultra-low subwoofer ; Equalizer; Reverberator; Effector; Delayer; Compressor; Limiter; Crossover; Noise Gate; CD Player; Recording Deck; Video Disc Player; Projector; Tuner; Song Player; Headphones, etc. Many devices are composed.

There are many types of loudspeakers: according to their energy conversion methods, they can be divided into electric, electromagnetic, piezoelectric, digital, etc.; according to the diaphragm structure, they can be divided into single cones, composite cones, composite horns, and the same There are many kinds of shafts; according to the diaphragm, it can be initially divided into cone type, dome type, flat type, belt type, etc.; according to the replay frequency, it can be divided into high frequency, intermediate frequency, low frequency and full band speakers; according to the magnetic circuit The method can be divided into external magnetic type, internal magnetic type, dual magnetic circuit type and shielded type; according to the nature of the magnetic circuit, it can be divided into ferrite magnets, neodymium boron magnets, and AlNiCo magnet speakers; according to the diaphragm data Divided into paper and non-cone speakers, etc.

The cabinet is used to eliminate the acoustic short circuit of the speaker unit, restrain its acoustic resonance, broaden its frequency response plan, and reduce distortion. The cabinet shape structure of the speaker is divided into bookshelf type and floor type, as well as vertical type and horizontal type. The internal structure of the box has a variety of methods such as closed, inverted, band-pass, empty paper cone, labyrinth, symmetrical drive, and horn type. The most used are closed, inverted and band-pass.

Crossover has the difference between power frequency divider and electronic frequency divider. The main functions of both are frequency band cutting, amplitude-frequency characteristic and phase-frequency characteristic correction, impedance compensation and attenuation. The power divider, also known as the passive post divider, divides the frequency after the power amplifier. It is mainly composed of passive components such as inductors, resistors, capacitors and other passive components to form a filter network, and send the audio signals of each frequency band to the speakers of the corresponding frequency band for reproduction. Its characteristics are low cost, simple structure, suitable for amateurs, but its disadvantages are large insertion loss, low power, and poor transient characteristics.

The difference between professional audio and home audio: Briefly analyze the difference between professional audio and home audio: professional audio generally refers to professional entertainment venues such as dance halls, KTV rooms, theaters, conference rooms, and stadiums. Different places, different requirements for movement and static, and various factors such as the size of the place, are equipped with sound system solutions for different places. General professional audio has high sensitivity, high playback sound pressure, good strength, and large receiving power. Compared with home audio, its sound quality is harder and its appearance is not very sophisticated. However, the performance of monitor speakers is closer to that of home audio, and their appearance is generally more exquisite and exquisite, so this type of monitor speaker is used in home Hi-Fi audio systems regularly.

Home audio equipment:

1. Audio source: The origin of the movement. Common audio sources in the home audio system include cassette recorders, CD players, LD players, VCD players and DVD players.

2. Expansion equipment: In order to use high-power speakers to produce sound, the signal output by the audio source generally needs to be power expanded. The current common expansion equipment is AV amplifiers, which are generally transistor amplifiers, but now some enthusiasts also love tube expanders.

3. Sound reproduction equipment:The speaker, the performance of which will directly affect the sound quality.

4. Connection line: including the connection line from the audio source to the power amplifier and the connection line from the power amplifier to the speaker.

The difference in sound quality:

The sound quality of speakers is very important. The sound quality determines the influence of music on people’s body and mind. The ancients are exquisite: to rule the country with etiquette and music is to use good sound quality and good music to edify people’s temperament and make people’s body, mind, and soul to reach a state of reconciliation, the body and mind of the person will have health improvement together. Therefore, the sound quality is equal to the health of the body.

Good sound quality provides people a feeling of empathy. This feeling is a touch from the depths of the soul, from the most authentic part of people. It feels like a mother’s love for her children, moisturizing things. Silent, but it does exist. Only one sound brings a shock of the soul.

The ultimate goal of the home audio system is to obtain the aspirational listening function, such as the sound function of a theater at home. But the family is different from the theater, so it requires different acoustics for different types of sound. It requires pop music, classical music, light music, etc. to be able to properly recover various musical instruments, and it requires a sense of presence with sound effects for watching movies.
