car speakers (SPEAKER), also known as car horns, its importance in the car audio system is more prominent, the whole sound system indispensable equipment. .
1 speakers use different environments
1, temperature: the temperature difference between the use of small household appliances speakers in the room, while the car to work outdoors, with large temperature differences in climate change hot and cold, so to anti temperature aging structure can not deform.
2, moisture: car in the rain, water walking sections will be subject to moisture when washing the car, so the car speaker to moisture, now use more cone chemical synthetic materials.
3, anti-dust: a room where speakers appliances less dust, and the car dusty, dust cover to prevent the voice coil required friction noise.
4, noise: considering various vehicle noise and reflections, the materials used are different, using a variety of different noise canceling design approach.
5, the limited-vehicle speaker mounting position, listening to the sound field positioning, treble different design angles. 7, small impedance: low supply voltage car toI want to get high power, impedance speakers are small, multi-use 4Omega; there 3.2Omega; and 2Omega; even 1Omega ;, using dual voice coil, the parallel method up 2Omega; even smaller, this method is very home audio less used.
6, vibration: car speaker anywhere by shock and vibration during movement of the car, the design firm can not be loose.
2. The structure and characteristics of the speaker
limited to car speakers installation problems, high, as the bass sound is difficult and family, is mounted on the same plane, is mixed with customary type methods, high, medium and low in a fixed frames, the majority of the coaxial type, there is also a bridge structure.
The automotive internal structure, better sound field positioning, the use of modular treble and bass separated, connected with passive crossover. In order to obtain high power and good dynamic characteristics tritone formula, it does not have to use a large size of the speaker, a speaker box using a half-box tetrasyllabic path and passive path radiant tetrameter.
1. Tweeter: Multi NdFeB titanium dome tweeter, neodymium silk dome tweeter, NdFeB magnets small size and a strong magnetic force, diaphragm vibration pure silk soft mold, this tweeter sound natural and full, treble legible, but also the use of pure carbon dome type tweeter dome styrene rubber coated polyester tweeter speaker, tweeter mounted in the multi-car dashboard and both sides of the door above, in particular the rotation direction of the support can be freely selected echo. Tweeter application more dimensions of 1 inch and 2Inch. Surface mounting type and form of mosaic.
2. subwoofer: car driving the car road noise and internal structural conditions often make bass weakened, install the appropriate high-performance subwoofer can be the ideal solution to this problem, so as to maintain the natural tone the balance sounds rich depth, breadth, and pure clear, subwoofer and refined using high strength aluminum frames, gold-plated terminals to enhance the overall performance of loudspeakers, having a superior conductivity properties over oxidation and prevent corrosion, a special reinforced bulletproof tympanic membrane, pressing cone epoxy resin coating, and the vent damper double pole extension, the extension and large strontium alloy magnet yoke. Subwoofer applications more size 8 inch, 10 inch, 12 inch, 15 inch, 18 inch
3. woofer: polypropylene multi-cone material, which is a polyethylene made from propylene high-strength thermoplastic resin such as polypropylene has excellent moisture resistance, oil resistance and heat resistance of soluble and extremely excellent, it is very robust, i.e., burst power stand, but also stand by a large volume, while having a high sensitivity , can by a suitable damping effect, show clear and fine vocal music charm, a multi-polypropylene blend iron pots carbon film. Coil heat resistance is good polyimides ammonium power management speaker voice coil bobbin material. Paper, natural rubber basin edge side deformities and fatigue can be prevented. Application of more squawker a size of 4 inches, 5 inches, 6 inches, 6.5 inches, coaxial and split.
