The reason why the sound system can be called sound, the most basic condition is that there is a function to play back the sound. In the sound system, at least the following points must be mentioned to qualify as sound. This sound system is no exception, car audio is no exception. Car audio mainly includes three parts: main unit, speaker and amplifier. The mainframe is the most important part of the car's audio, just like the human brain, what kind of sound to make, it has to be controlled by the brain. Currently popular hosts include CD host, MP3 plus CD disc box and CD/DVD/car MP5 console. MP5 console has replaced the car CD audio system in general, and the massive hard disk capacity has replaced the traditional disc. Car MP5 has become the mainstream today. Software and media What do you want to hear? Traffic conditions show? Then you have to turn on the radio station and tune to the correct channel. Want to watch TV in the car? It's even simpler. The LCD screen is one of the protagonists of the car audio system, even if you want to watch the DVD. Want to listen to music? Put a favorite record, whether it is CD, MD, or cassette, just mention which singer's song is included, you like Liu Jialiang, I love to listen to hit-pop, whoever listens to who will put the record, buns buns Every love. Sound source The mechanism that can decode software and multimedia is called the sound source. This proper noun seems to be difficult to understand, but it is extremely simple!  Broadcasting is called tuner î€, commonly known as radio;  playing cassette is called cassette player: as for playing CD, it is called CD-Player, î€ is also a laser disc – very simple! Pre-level signal controlî€ To put it simply, the pre-stage is before the post-stage. We generally refer to the amplifier as the post-stage. Therefore, between the audio source and the amplifier, all the processing elements for the music signal are called the pre-level. For example, the control of the volume on the car audio host is part of the pre-stage, which controls the strength of the signal. In other audio equipment, the front-end control part that is more commonly seen, as well as treble and bass adjustment, left and right balance, front and rear volume adjustment, and Loudless loudness control. Also more complicated is the Audio Equalizer (EQ), which has the same functions as the bedside sound, which has the same function as a multi-segment frequency adjustment tone and also displays different pattern screens. In addition, the digital audio processor DSP is also standard equipment for many mainframes. Simply speaking, it simulates the sound characteristics of a space such as a gymnasium, a ballroom or a concert hall. All in all, the organization that deals with or adjusts the signal is the predecessor. Power amplification mechanismî€ Most of the sound signals of the pre-stage control are only a few volts, which is not enough to drive the single unit. Therefore, the signal must be eaten with “powerful pillsâ€, so that the intensity of the signal is stronger, so that it can be calculated by watt (W). The mechanism that strengthens the signal into a power output is called a power amplifier, which is also known as a power amplifier. In general, the total output power of the sound system, that is, the sum of the output power of all the power amplifiers in the system, is used as the classification of the sound system in the size series. Speaker î€ A mechanism that turns electrical energy into sound waves is called a speaker. Perhaps the reader has guessed that the speaker is a commonly known speaker! Right? It can only be said to be half right. A mechanism that can turn a signal into a sound, in addition to a circular or elliptical reciprocating dynamic speaker unit, there are other types of speakers! For example, a ribbon-type ribbon that emits sound with a metal belt and an electrostatic speaker that uses a static-driven planar diaphragm also have a place in the sound. However, in the car audio, the moving-ring speaker is still the mainstream. In addition to the American Infinity and the Taiwanese EVIL, there are ribbon-type car tweeters, all of which are common moving coil type monomers. Transmission mechanismî€ A complete sound system, wire is an indispensable combination, but the wire is often overlooked. In fact, the quality of the wire will directly affect the quality of the sound, because the design of the wire from the material, the twisted structure to the diameter, insulation and impedance values ​​and specifications, will affect the transmission of signals or power. In terms of the use of wire materials, wires with different design orientations, such as power supply, grounding, start-up, signal, speaker, fiber, and special system wires, are required for different materials. There is a difference. For example, for a speaker cable that requires sound quality, the purity of the material must be as high as possible, otherwise too much impurities will affect the full play of the sound. In addition, the terminals between the wire and the equipment are also very important. The firmness of the contact, the size of the contact area, the joint design and material, and the good grounding will also have a significant impact on the sound effect. No matter the size of your car's audio system, when you turn on the car's audio, as long as you can provide the music you want to listen to, and enjoy your hearing, it is the perfect car audio system. 72V Battery Pack ,Lithium Ion Battery Pack,Lithium Battery Pack,Battery Power Pack Zhejiang Casnovo Materials Co., Ltd. , https://www.casnovonewenergy.com
