Modern manufacturing technology, giving audio a new life, a variety of audio, from small and exquisite can be installed in the pocket, to a few trucks to pull through the equipment, endless. For example: cell phone stereo, mini stereo, U disk radio stereo, bookshelf stereo, floor stereo, home theater, surround sound, karaoke stereo, square stereo, stage stereo, conference stereo, hotel, bookstore stereo, bar stereo and so on. Please remember, can be called audio, its sound effect should have three elements: tone, pitch, loudness three elements.
Anything, should be people-oriented, audio is no exception. From the perspective of human needs, audio can be divided into: personal audio; family audio; application of audio three categories. Personal audio, family audio, people see more, may be better understood. Applied audio bias professional, the use of not universal, so, some strange. This is the reason why this article would like to focus on.
Applied audio, that is, in the public **** place application of audio. Including: square audio, square dance speakers, K song audio, conference audio, stage audio, store audio and so on. What exactly is the difference between this category of audio? How to distinguish? What is the difference between square audio and square dance audio, how to differentiate. The main feature of the square sound is the need for a large environment, for example, Tiananmen Square parade, from the podium to the street array of soldiers, all need sound which is a huge sound project. Another example, the campus of the morning exercise, hundreds of students can hear the sound. Then, square dance sound? She is a team, a few, dozens, hundreds of people can hear the sound is OK . Obviously, it is the size of the space, the number of personnel to distinguish. Therefore, the distinction between square audio and square dance audio, from the point of view of the power required, square audio is high-power, while square dance audio is small power. From the point of view of manipulation, square audio is a professional manipulation, and square dance audio can be manipulated by everyone.
So, we have come to a conclusion, the difference between the sound of the environment size, power size, and the degree of ease of manipulation. This is one of the methods of differentiation. Secondly, the use of function is also an important means of distinction. Still take the square sound and square dance sound as an example. Square sound, people need to play background music before entering the field, and sometimes there are sub-field, the need for sound synchronization, the host can use a wired microphone, and the head of the parade need a wireless microphone, the soldiers need to answer the feedback, the audience needs to join in the cheering, the singer needs to reflect the song (synchronization and synthesis), etc., need to be all parties to cooperate with the director of the general control room, the director of the sound reinforcement, in order to complete the successful completion of the plaza, Pickup, synchronization, synthesis, compilation and broadcasting, general control. And square dance sound, it can be said that she is simple, as long as you can broadcast music or speech or K song on it. Functional differences are vastly different. Thus, the investment price difference is derived.
The above examples, it can be seen that the application of sound can be distinguished from five aspects: 1. application environment difference; 2. power size difference; 3. manipulation of the difference between easy; 4. function how much difference; 5. price difference.
