Vibration and acoustic radiation problems with the speaker cone. Theoretically, the forced vibration state of the cone is ignored and not neglected at various frequencies. The frequency characteristics of the radiated sound pressure, sound power and directivity pattern are calculated.
The surface of the speaker cone needs to cover the insulation. The coil is also a factor in the size of the power level of the speaker. The "burning horn" is actually a voice coil, which is impossible because the voice coil wire is burned through the insulation layer. The higher the temperature at which the insulating material can be exposed, the greater the function of the voice coil. Therefore, the insulating layer becomes one of the crux of the promotion power level. Some speakers mention the application of the XXX low temperature resistant coating. This is the insulation layer is resistant to low temperatures. Advantages and unique new technology analysis are as follows: First, the technical status of speakers and speakers 1. Professional speakers are only used for speakers and speaker boxes for movies, stage, halls, stadiums and other occasions. In recent years, with the development of new materials, new technologies, new structures, new processes, stereo technology, digital technology applications, CD and VCD, professional speakers and their systems have also achieved great development, new products have been Emerge.
The speaker cone design and production instrument can meet the needs of different merchants and achieve the balance between the quality and price of the speaker cone product. The speaker's ability to resist overload is increased, but it also affects the dynamic range of the sound, making the sound range not wide enough, and the tone feels blurry and dim. To this end, the *** method or the measures taken on the power amplifier, so that its output does not suffer from clipping and efficiency overload. In recent years, with the development of digital audio technology, the requirements for speakers have become more demanding. In order to meet the requirements of technological development, to meet the needs of businesses.
The distinctive advantage of the speaker cone is that the key technology of using a directional horn such as a new material is that new products with different shapes of the horn have been emerging. The world's major speaker companies have introduced various forms of AV speaker speakers. They not only have advanced technical properties designed to promote bass. Three-way crossover speaker: DSP surround sound developed on the basis of two-way crossover. DSP surround sound is a 30-inch cone subwoofer developed by two 200mm woofer EVs with digital processing technology. In recent years, the subwoofer's cone can move up and down by 50px, and the 6-inch woofer can achieve 100dB sound pressure level at 50Hz, which is not enough for traditional woofer. Representative products such as KEF's AV1 active active subwoofer. The speaker cone voice coil is the driving unit of the cone cone speaker. It is wound on the paper tube in two layers with very thin copper wires. Usually it is wound around several tens of turns, also called coil, placed on the magnetic core column and guide. The magnetic plate is formed in the magnetic gap. The voice coil is fixed to the paper cone. When the sound current signal enters the voice coil, the voice coil vibration drives the paper cone to vibrate.
