Detailed knowledge of car audio related parameters[汽车美容装饰]

carIt is the place where music is most needed: when you are driving alone on a vast journey, the melodious music can sweep away the fatigue of the journey, and run down a journey full of energy; when you are stuck in a sea of cars and do not know where to go, beautiful music can ease A nervous mood, if equipped with electronic maps and satellite navigation devices, can also help you get out of trouble as soon as possible; the car is also the most unsuitable place for listening to music: noise and resonance will greatly reduce the beautiful music; the space in the car is limited. Coupled with the reflection of sound waves from steel plate and glass, all these make car audio and home audio have completely different characteristics.Shenzhen FeiyangCar stereoMr. Liang, a senior technician in the Changsha store, has been engaged in audio modification for nearly ten years. At the request of the author, he explained the relevant parameters and terminology knowledge of car audio:

Power: It is one of the most important parameters of the audio system, which means the capacity of the audio system with load. There are three types of power: one is the peak power (PMPO), which represents the maximum output power of the system at a moment; the other is the maximum continuous output power, which is a very important indicator; the third is the maximum undistorted power, which is for high-fidelity audio systems. Is very important. Usually the system with a continuous output power of 50W, the peak power can reach more than 1000W, and the undistorted power is only about 20W.

Signal-to-noise ratio: It is an important parameter that indicates the sound quality of the audio system. It is the ratio of the output signal strength to the noise signal strength, taking the common logarithm and multiplying by 10, the unit is decibel (dB). The signal-to-noise ratio of inferior portable radio cassette recorders is less than 30 decibels, while the signal-to-noise ratio of high-end CD players can reach more than 90 decibels. For example, the Japanese Clarion CD host is one of the best;

Frequency response: abbreviated as frequency response, it is an index that indicates the broadness of the system's reproduced sound range. The frequency range that the human ear can feel is 20-20000 Hz. The frequency response of high-quality speakers, power amplifiers and CD players can reach this range. For example, the frequency response of the world's top speakers, MOREL, and the JBL power amplifier of "America's Zun" is 5-25000HZ. Far beyond the normal indicators, it can be called a giant in audio equipment.
