1, the speakers
The speaker has a variety of FenLeiShi: according to the change can methods can be divided into electric, magnetic, piezoelectric, digital, etc; According to the diaphragm structure can be divided into single basin, composite paper paper, composite guide, coaxial, etc; According to the diaphragm can be divided into beginning cone basin type, ball type, plate type, belt conveyor, etc; The replay can be divided into high frequency, intermediate frequency, low frequency and frequency band the speaker; Can be divided into the form of the magnetic circuit magnetic type, magnetic type, double magnetic circuit type and block type, etc; According to the nature of the magnetic circuit can be divided into ferrite magnets, boron neodymium magnets, alnico magnets speakers; According to the diaphragm materials can be divided into paper and paper cone speaker, etc.
A, the most widely electricity-powered loudspeaker, it USES voice coil and diaphragm between constant magnetic field force vibration and sound. Dynamic bass speaker in the majority with cone tub, mediant loudspeaker is cone tub or ball type more, high-pitched loudspeaker with ball type and belt conveyor, the cylinder is commonly used.
B, the loudspeaker cone basin of simple structure, high energy conversion efficiency. It USES the diaphragm material is given priority to with the pulp material, or material such as wool, silk, carbon fiber, in order to increase its rigidity, damping and waterproof performance. Basin of a new generation of dynamic cone speaker use non-paper-made diaphragm materials, such as polypropylene, mica polypropylene carbide, carbon fiber textiles, bulletproof, glass fiber cloth, hard aluminum foil, CD ripple composite material, such as improving performance improvement.
C, ball loudspeaker has a soft ball and hard ball. Soft ball diaphragm of the speaker color silk, silk, cotton, chemical fiber and composite materials of phenolic resin impregnated, its characteristic is mellow replay sound quality; Hard ball speaker diaphragm colour materials such as aluminum alloy, titanium alloy and beryllium alloys, its characteristic is replay sharp sound.
D, no radiation mode of the speaker and the loudspeaker cone basin is different, this is after the diaphragm vibration, sound after the trumpet to spread out again. Its characteristic is acoustic conversion and high radiation efficiency, distance, small distortion, but replay a narrow band and directivity.
E, the belt type of speaker voice coil directly manufacture throughout the diaphragm (aluminum alloy polyimide film, etc.), direct coupling between voice coil and diaphragm. Voice coil production of alternating magnetic field interacting with a constant magnetic field, the vibration and radiation belt type diaphragm sound waves. Its characteristic is fast response speed, small distortion, replay the sound quality is exquisite, administrative levels feels good.
