Nowadays, more and more people are buying cars. It is a pleasure to drive and listen to music on the way to and from work. For audiophiles, audio knowledge to know much, but for those who usually do not have time to pay attention to friends, it is easy to confuse the performance of car audio speakers and home appliance speakers, in fact, the two are not the same. Below we through the understanding of car audio speaker performance, structure and characteristics, we can know what is different between them.
The environment used is different
1, temperature: household appliances white microphone used in the room temperature difference is small, and the car in the outdoor work, with the climate change difference in temperature, so to resist the temperature aging structure can not be deformed.
2, moisture-proof temperature: the car in the rain, walk the water section, the car at any time to be threatened by moisture, so the car speakers to prevent moisture, now more use of chemical synthetic materials sound basin.
3, anti dust: home appliance speakers in the room to use less dust, and dust in the car, need to use a dust cover to prevent voice coil friction noise.
4, vibration: car speakers anytime and anywhere by the vibration of the car movement impact, the design should be firm can not loosen.
5, noise: considering all kinds of noise and reflection in the car, the materials used are also different, the high pitch Angle design is different, using various ways to offset different noise.
6, impedance is small: car power supply voltage mea culpa, want to obtain big power, the impedance of loudspeaker is small, use 4 ohm or 3.2 ohm or even 2 ohm more, use parallel method can reach 0.5 ohm, this kind of method home acoustics is rarely used.
Be limited to the problem that car horn installs respect, tall, in, low and domestic acoustics are same very hard, install on same plane, what is customary is the method of mixed model, fix tall, in, bass on a basin frame, majority uses coaxial type, also have to use bridge to connect type structure. According to the internal structure of the car, the sound field positioning is better by combining the pitch and the bass, connected with the passive divider. In order to obtain high power and good dynamic characteristics of the whole domain, it is not necessary to use a large size horn, using a box horn, with half box four-tone circuit and passive radiation four-tone circuit. Due to the small area of the car, but also to obtain a wide frequency, the horn design into an ellipse such as: 6 x 6 inches, 5 x 7 inches, 4 x 6 inches, etc..
Loudspeaker: Use ndfeb half spherical titanium high-pitched, ndfeb and more ball silk high, small volume and powerful magnetic ndfeb magnet, the sound film using pure silk soft mode, this kind of loudspeakers sound natural and plump, high clear, also has the use of loudspeakers of pure carbon dome, besmear of styrene rubber dome type polyester loudspeakers, etc., The treble is installed on both sides of the car dashboard and above the door on both sides. The special rotating support can choose the reverberation direction at will.
Medium woofer: Sound material use polypropylene, which is composed of acrylic polymer of high strength polypropylene thermoplastic resin with excellent wet resistance, solvent resistance and heat resistance is very outstanding, it is very strong, the bear power burst, also stand by large volume, high sensitivity at the same time, by the appropriate damping effect, show a clear and fine music verve, The use of carbon iron mixed with polypropylene basin film. Polyimonium is the material for the voice coil bobbins of high power loudspeakers. The use of natural rubber skin on the rim of the basin can prevent deformity and fatigue.
Ultra low tone horn: Pavement noise in the car and car has been weakened by the internal structure conditions often make the bass effect, install the appropriate performance subwoofer speaker can be the ideal solution to this problem, so as to keep the natural balance of tones sounds depth, breadth, and clear and pure, subwoofer speakers adopt high strength of refined copper and aluminum frame, gold-plated terminal promote the overall performance of the horn, Excellent ELECTRICAL PROPERTIES AND PROTECTION AGAINST OXIDATION AND CORROSION, SPECIAL BULLETPROOF REINFORCED TYMPANUM, EPOXY FINGER COATED PRESS PAPER BOWL, DOUBLE DAMPER VENTILATION, LONG POLE, EXTENDED YOKE AND LARGE STRONTIUM ALLOY MAGNETS.
If you ARE GOING TO upgrade YOUR CAR audio level, it is essential to choose a multi-channel system, which uses multiple power amplifiers and frequency division networks to amplify high, medium and low frequencies separately. Each speaker will not interfere with each other, respectively manage their own frequency range, comprehensive sound effect is mellow and beautiful, so that the perfect reproduction of music, so that you feel music and car integration.
