Car acoustics to the car, it is the equipment of a kind of auxiliary sex, also do not have what influence to car function, but, rise as what people is born vivid character, everybody is taller and taller also to the requirement of level of acoustics seeing and hearing, car manufacturer also takes the sound equipment of the car seriously increasingly, but to reduce cost, they configured common sound equipment only, although have the high-grade car of the cent of machine of CD, VCD, also be to compare simple, cannot achieve result of perfect seeing and hearing, so, after a lot of people bought new car, the love car that is oneself in succession installs sound equipment. Here, gallop be able to bear or endure the secret that conserve of general car hairdressing tells everybody acoustics of car of choose and buy even the technician of locksmith:
Above all, want to have perfect acoustics, must go to professional place, make the technician over there right original sound system undertakes changing one's costume or dress or change.
Next, the main component of car acoustics is lead plane, result puts He Yangsheng implement, when the choose and buy, want special attention the function of this 3 parts. Judge the actor of low quality of acoustics lead plane, the directest method views its technical index namely. Basically judge from the following respects:
1, output power: The power great majority of bid of present lead plane place is musical power, between 40W-60W, power cannot too big.
2, frequency answers: The frequency limits that person ear can hear is between 20HZ-20KHZ, accordingly this index should reach this numerical value the least, and wider better.
3, letter a confusion of voices compares: It is the scale that points to musical signal and noise, acoustics of general and high-grade car is in 90DB above, this numerical value has been jumped over greatly more.
4, harmonic is lack fidelity (THD) : What this index reflects sound resurgence is reductive degree, numeric smaller specification is reductive degree taller, acoustics is better also.
Result the heart that putting is sound system, result the volume that puts power, the stand or fall of quality is right of music broadcast the intention with a crucial move. The result of average car is put design inside lead plane, power is 10W commonly, 45W, but such cannot listen respectfully is mutiple level the digital music of high-power, want to make sound achieves optimal result, must increase independent power amplifier in the system, its purpose is the voltage of 12 bend over power source rises to 35 bend over, 45 bend over, drive high-power horn with tall voltage, so dynamic limits increased, the broadcasting with musical more perfect talent comes out. So how is result of choose and buy put?
Above all, result put power should match with the power photograph of the horn; Next, should choose to have inside buy scale down implement result put, such meetings make the system is had expanding, can be opposite freely result put and field sound implement undertake assorted, also make adjust at the same time go easily simply, make the acoustic quality of system of a complete set of gets rising. Notice to choose bigger radiator as far as possible even when the choose and buy, because of the output of high-power, inevitable meeting produces bigger quantity of heat, medicinal powder heat is to maintain result one of main factors that put main job.
