The technology and knowledge of the speaker unit of the relevant equipment of the dubber
When it comes to supporting equipment for sound, the most common one is the sound unit radio recorder, which is also the sound sewage treatment equipment of people we have come into contact with since childhood. But with the development of technology, the sound related equipment we see is becoming more and more advanced. Professional role dubbing equipment, two loudspeakers, and studio equipment all use traditional and advanced human voice processing techniques. [Chinese dubbing]
Someone has made a lot of statistics on other factors affecting the main parts of the digital audio player. The results show that speakers and Bluetooth speakers account for 60% - 70%, program sources account for 15% - 20%, and amplifiers account for 15% - 20%. It can be seen that speakers and Bluetooth speakers are very important in stereo recorders.
Two loudspeakers and wireless speakers are the most important parts of stereo recorders, and the quality level cannot be ignored. Next, Xuanyin Animation dubbing network will introduce the relevant knowledge of the two speakers in detail.

First, the speaker is essentially an ultrasonic transducer that converts DC electrical energy into mechanical energy into internal energy. Its conversion efficiency is not high (generally about 2% - 5%). After working, most of the electrical energy consumed will be converted into heat energy and consumed, so that the voice coil does not heat.
Therefore, it is necessary to use a high strength adhesive between the voice coil and the structure, as well as between the voice coil and the vibrating film, to avoid loosening due to the low heat of the voice coil. [English dubbing]
Second, the division method of the speaker structure: the internal structure of the red button ring-type speaker can also be divided into four types of ordinary film speakers, pencil rubber edge film speakers, two speakers of the Shenji type, elliptical speaker units and dual film sound generating units.
According to the internal structure and energy conversion mechanism, the sound generating unit can be divided into four types: dynamic two speakers (also known as electric two speakers), piezoelectric speaker units, and reed type speakers. Among them, the dynamic sound generating unit has the best comprehensive electrical performance and is most widely used in video recorders.
The main principle of fixed frequency after operation of the third speaker: according to the other operating frequency range of the speaker, the two dynamic speakers can be divided into four types: passive radiator, mid-bass speaker, tweeter and full-band speaker.
Their working audio range: 15-800400khz for full-frequency speakers, 500-6000hz for the two mid-range speakers, and 4000-20000400khz for the tweeter speakers. The two full-band speakers can cover the full range of mid-range, mid-range and tweeter as a whole.
In our daily life, we listen to music brands, advertisements, television broadcasts, etc., all use the result technology of sound processing of advanced speaker units, so we are not familiar with speakers. We need to know them well, so that we can better master the sound recording and animation dubbing.
