I. The characteristics of stage acoustics are different.

 

 

 

(1) Professional speakers need to reproduce ultra-bass sounds dynamically. Professional speakers have many very low frequencies, such as explosions in movies, disco bass drums, etc. The frequencies are even lower than 20Hz, and the louder pressure level can exceed 1dB. Such sounds are not necessarily heard by the ear, but by the sound. Voice. It gives people the feeling that a hi-fi speaker doesn't need it.

 

 

 

(2) In the three aspects of voice dialogue, music and sound effect, music requires higher fidelity, while movies need better sound effect, because people pay more attention to visual and linguistic dialogue than details when watching movies. Music, so professional audio systems are not too many. Emphasizing the performance of sound, paying attention to the sound effect of loud and loud sound, setting off the atmosphere, high-fidelity speaker is a kind of high-fidelity sound, requiring accurate reproduction of the original sound, paying attention to the frequency of direct and broad and beautiful sound, therefore requiring fidelity higher than professional speakers.

 

 

 

2. Different structures of speakers

 

 

 

Professional speakers are usually used in large occasions, such as large halls, stadiums and so on. In order to create an atmosphere for a sound system, its system is usually composed of multiple speakers, and a special supersonic box is used to highlight the bass effect. Music programs are usually recorded in two channels, because the speaker only needs two speakers. Use a bass box.

 

 

 

3. The requirements for timbre are different

 

 

 

The speaker has a decisive influence on the sound system of the sound system. The speaker emphasizes the perfect playback of music, the taste of music, the expressive force of fine details, and the use of soft and delicate sound. The professional sound system mainly uses language and effect sound playback, and pays attention to the momentum and strength of sound. In order to produce more shocking sound effects, the speaker needs to be controlled. Sound, with a good sense of speed, from light songs to thunder and lightning can perform well.
