Desktop Speaker Classification

Edit:Shenzhen LS Technology Co.Ltd      Date:Jul 10, 2017

Desktop Speaker There are many kinds of speakers in the classification: according to its conversion method can be divided into electric, electromagnetic, Desktop Speaker piezoelectric, digital and other; according to diaphragm structure can be divided into single cone, composite cone, compound horn, with Shaft, etc., according to the beginning of the diaphragm can be divided into cone-type, dome-style, flat, belt and other; Desktop Speaker according to the playback frequency can be divided into high frequency, Desktop Speaker intermediate frequency, low frequency and full band speaker; Desktop Speaker Can be divided into external magnetic, internal magnetic, dual magnetic and shield and other kinds; according to the nature of the magnetic circuit can be divided into ferrite magnets, Desktop Speaker neodymium boron magnets, Desktop Speaker aluminum nickel cobalt magnet speakers; Sub-paper and non-paper cone speakers.

 A, electric speaker is the most widely used, Desktop Speaker it uses the voice coil and the constant magnetic field interaction between the diaphragm vibration and sound. Electric subwoofer to cone-type majority, midrange speakers for the cone-type or the top of the ball, the tweeters with the top of the ball and belt, the type of commonly used.

    B, cone-type speaker structure is simple, Desktop Speaker high energy conversion efficiency. It uses the diaphragm material to pulp material, or mixed with wool, silk, carbon fiber and other materials to increase its rigidity, damping and waterproof performance. The new generation of electric cone speakers use non-paper diaphragm materials, such as polypropylene, mica carbonized polypropylene, Desktop Speaker carbon fiber textile, bulletproof cloth, Desktop Speaker hard aluminum foil, CD corrugated, glass fiber composite materials, improve performance.

    C, the top of the dome has a soft dome and hard dome of the points. Soft ball-shaped speaker of the diaphragm color silk, silk, impregnated with phenolic resin cotton, Desktop Speaker chemical fiber and composite materials, which is characterized by replay sound soft; hard dome speaker diaphragm color aluminum alloy, Desktop Speaker titanium alloy and beryllium alloy and other materials, It is characterized by crisp playback quality.

    D, trumpet speaker radiation and cone-type speaker is different, which is in the diaphragm vibration, the sound through the trumpet and then spread out. Its characteristics are electro-acoustic conversion and radiation efficiency is high, distance, distortion is small, but the playback frequency and directional narrow.

    E, the voice coil of the belt speaker is directly formed on the diaphragm (aluminum alloy polyimide film, etc.), and the voice coil is directly coupled with the diaphragm. Desktop Speaker The alternating magnetic field produced by the voice coil interacts with the constant magnetic field, Desktop Speaker so that the belt diaphragm vibrates and radiates the sound wave. It is characterized by fast response, small distortion, Desktop Speaker replay sound quality, good sense of hierarchy. [Fenye]

    Box

    The box is used to eliminate the short circuit of the loudspeaker unit, Desktop Speaker suppress its acoustic resonance, broaden its frequency response range and reduce distortion. Desktop Speaker Speaker box shape structure of the bookshelf and floor of the points, as well as vertical and horizontal points. The internal structure of the box is closed, inverted, banded, Desktop Speaker empty paper basin, labyrinth, Desktop Speaker symmetrical drive and trumpet and other forms, the most used is closed, inverted and band The

    Floor speakers are large speakers, box height above 750MM, shelves speaker box height below 750MM, 450MM ~ 750MM between the medium-sized bookshelf speakers, Desktop Speaker 450MM following the small bookshelf speakers.

    Home theater system for the front speakers for the vertical speakers, the use of bookshelf-style, but also the use of floor-style, which depends on the size of the audio-visual room, power amplifier size and personal preferences may be. Usually, Desktop Speaker for the audio-visual room in the 15 square meters below, Desktop Speaker should use medium-sized bookshelf speakers; less than 10 square meters should use a small bookcase; Desktop Speaker more than 15 square meters of the room, you can choose medium-sized bookshelf speakers or floor box. Front speaker, center speaker and surround speakers are mostly inverted phase design, followed by closed and 1/4 wavelength loading, Desktop Speaker labyrinth and so on. Subwoofer with band-pass and double-cavity double-open-type majority, Desktop Speaker followed by inverted phase, closed.
