Description

Cold extrusion processing device for U-shaped iron of loudspeaker

Technical Field

The utility model belongs to the technical field of the speaker, especially, relate to cold extrusion processing device of speaker U iron.

Background

The speaker is also called a horn. The loudspeaker is a transducer for converting an electric signal into an acoustic signal, and the quality of the loudspeaker has great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, and is the most important component for the audio effect. Loudspeakers are of a wide variety and vary widely in price. The audio frequency electric energy makes the paper cone or the diaphragm vibrate and generate resonance (resonance) with the surrounding air through electromagnetic, piezoelectric or electrostatic effect to make sound. The low-grade plastic sound box cannot overcome resonance due to the fact that the box body is thin, and has no tone quality (a part of designed plastic sound boxes are far better than inferior wood sound boxes); the wooden sound box reduces the sound pollution caused by the resonance of the box body, and the sound quality is generally better than that of the plastic sound box. Generally, multimedia sound boxes are designed in a double-unit two-frequency-division mode, a smaller loudspeaker is responsible for medium-high output, another larger loudspeaker is responsible for medium-low output, and the materials of the two loudspeakers are selected according to the selection: the high pitch unit of the multimedia active sound box takes a soft dome as a main part (in addition, a titanium film dome and the like for simulating a sound source) and can reduce the ice-cold feeling of high-frequency signals by matching with a digital sound source, thereby giving people the feeling of ice-cold, delicateness and soul. The multimedia loudspeaker box has more soft ball tops such as a silk film with better quality and a PV film with lower cost. The bass unit determines the characteristics of the sound box, and the selection is relatively important, and the most common ones are as follows: the paper cone is also provided with a plurality of glue-coated paper cone, a paper-based wool cone, a compressed cone and the like, common loudspeakers are natural in tone, low in price, good in rigidity, light in material and high in sensitivity, the defects of poor moisture resistance and difficulty in control of consistency during manufacturing are overcome, and the paper cone is manufactured in a top-level HiFi system according to a ratio, so that sound output is very average, and the reducibility is good. The bulletproof cloth has wider frequency response and lower distortion, is the first choice for people who love powerful bass, and has the defects of high cost, complex manufacturing process, low sensitivity and poor light music effect. The wool weaving basin is soft in texture, has excellent performance on soft music and light music, but has poor bass effect and lacks strength and impact. PP (polypropylene) basin, it is popular in the top-grade sound box extensively, the uniformity is good, the distortion is low, all aspects of performance can be circled and can be some. In addition, fiber-type diaphragms and composite diaphragms are rarely used in popular sound boxes due to their high price. Naturally, the larger the speaker size, the better, the larger the size of the woofer, the better the performance in the low frequency part, which can be selected among the options. Enclosures made with high performance speakers mean lower transient distortion and better sound quality. The loudspeaker of the common multimedia loudspeaker box woofer is mostly between 3-5 inches. Enclosures made with high performance speakers also mean lower transient distortion and better sound quality.

Traditional speaker U indisputable cold extrusion processingequipment is difficult for adjusting mostly, can not extrude according to the thickness of U indisputable when using to can influence the extrusion quality of U indisputable.
