The speaker's structure
our most common speakers for electric type cone paper bowl. Electric cone speaker that in the past, we often say the speaker cone, although now diaphragm still to paper basin mainly, but at the same time, there many vibration membrane of polymer materials, metal diaphragm, with cone loudspeaker calling worthy. Tapered paper cone loudspeaker is generally consists of three most composition:
1, magnetic loop system (permanent magnet & lt; magnet & gt; and stem & lt; yoke "U iron or T iron ', a guide magnetic plate & lt; Hua our & gt;).
2, vibration system (vibration plate < paper bowl, voice film > voice coil).
3, a supporting system (centering support chip < elastic wave >, frame, cushions, terminal board). < br / > details on the above three systems:
1, a voice coil, voice coil is tapered paper cone loudspeaker drive unit, it is very fine copper wire (copper / aluminum) divided into two layers (four layers) around the bone with (paper tube / aluminum / film, etc.), generally around a few laps, placed in the magnetic core and the guide magnetic plate constitutes a magnetic suspected gap. The voice coil is fixed with the paper bowl. When the sound current signal is connected to the voice coil, the vibration of the voice coil is driven by the vibration of the paper.
2, paper basin (drum paper): Cone of paper basin speakers of the conical diaphragm used in many types of materials, there are generally two types of natural and man-made fibers. Natural fiber cotton, wood, often using wool, silk, rayon, nylon, rayon just using glass fiber etc.. Because the paper basin is a speaker of the sound radiation device, in a large extent determines the speaker's voice performance, so no matter what kind of paper bowl, the requirements of both light and rigid, can not be due to environmental temperature, humidity changes and deformation.
3, folding ring (edge flange): folding ring is to ensure that the paper basin along the axial movement of the speaker, limit horizontal movement and set up, and at the same time to stop the paper before and after the air dare to flow. The material of the folding ring is used for the material of the common paper basin. It is also used in plastic, natural rubber and so on.
4, formed by the hanging side and elastic wave of rigid or compliant mobile speed of the cone, the horn all flexible, elastic wave provides about 80%, suspension side to provide about 20%, there are two functions of suspension side, its original work is to keep the voice coil in electrode gap in the heart, however, for the
5 mode of vibration cone edge, damping effect caused by the suspension side is very important, choose drama hanging edge thickness and material to change the reaction of cone horn, distortion of damping and preventing back cone rear sonic reflection can change with the distortion in the model of amplitude and phase, which makes it become a complete cone element and can be implemented in response to the.
6 tool, the damper (Dan Bo): o.d.meter tablets for the binding site to support voice coil and cone, the vertical and not skew. Centering support chip has many concentric rings, the voice coil in the magnetic gap freely on the move without lateral movement, to ensure sound does not ring and the guide magnetic plates collide. Centering support chip dust cover is to prevent external dust fall in the magnetic gap, to avoid dust and voice coil friction, and the speaker occurrence of abnormal sounds. < br / > (centering support chip) elastic wave has some features. The second function is keep the voice coil centered in the gap, also put forward to apply for a avoid external layer of ash particles penetrated inside the gap. At the beginning of the elastic wave is to provide the horn monomer of restoring force. However, elastic wave of hardness and impact horn resonance (FO), the loudspeaker resonance is supple and quality function.
