Embodiment Construction

[0051] 1. Pure tweeter

[0052] Because there is no mechanical processing equipment, the purchased domestic tweeter is used now.

[0053] A) Disposable Harm brand small treble, silver film 25mm, magnet 40mm; first remove the plastic cover, insert a cylindrical thick paper with a height of 8mm into the magnetic gap, and raise the bottom of the magnetic gap to touch the voice coil The position of the port, and then insert the voice coil and use glue to stick the voice coil port to the bottom.

[0054] B) Detachable Feilo YDQG10-4 titanium film dome tweeter, remove the voice coil frame, make a cylindrical iron piece with a diameter of 25mm and a height of 13mm, insert it into the magnetic gap, and the bracket is about higher than the plane after inserting the voice coil, tighten it Screws press the voice coil tightly over the bottom of the added magnetic gap.

[0055] After completing the above steps the Pure Tweeter is complete.

[0056] 2. Clean woofer

[0057] Because ther...

Abstract

The invention aims at providing a new idea of moving-coil loudspeaker pronunciation and structure reconstruction and a general method of a technology for realizing the new idea. By using the method, two problems encountered during decades of development process of the loudspeaker can be solved, wherein the two problems comprise that: electro-acoustic conversion efficiency is low and non-linear distortion is large. The high pitch loudspeaker created in the invention is the ultra-low distorted high pitch loudspeaker of diaphragm jitter pronunciation. The clean bass loudspeaker created in the invention is the ultra-low distorted bass loudspeaker whose voice coil displacement is restricted in a linear area. The full-frequency coaxial loudspeaker created in the invention is formed by coaxial assembly of the pure high pitch and the clean bass loudspeakers. And magnetic-force energy storage inductor and a magnet are added. A no-prescaler technology is used to perform connection. Therefore, the full-frequency coaxial loudspeaker possesses the ultra-low distortion. According to the invention, a tradition loudspeaker structure is changed. If the technology provided in the invention is used in a domestic common loudspeaker, the domestic common loudspeaker can be promoted to a high-grade loudspeaker level. If using units and the no-prescaler technology, a manufactured speaker box can reach a top high fidelity level.

Description

technical field [0001] What the present invention relates to is the basic unit of making various sound reproducing devices—speaker. The present invention is a method invention, aiming at pointing out the new concept of loudspeaker sounding and the new structure of the structure and the general method of realizing the technical process of the new concept and new structure. According to this method, the bottleneck problem encountered in the development of loudspeakers for decades will be solved. According to this method, the quality of the loudspeaker will also be raised to new heights. In particular, the present invention relates to a general approach to the design and manufacturing process of pure tweeters, clean woofers, and full-range coaxial speakers. The so-called pure tweeter is an ultra-low distortion speaker with a pronunciation range above 2.5KHZ and no displacement of the voice coil; the so-called clean woofer refers to an ultra-low distortion speaker with a pronunc...
