High pitch hem and well bass hem integration vibrating diaphragm
Technical Field
The invention relates to a vibrating diaphragm of an electric loudspeaker, in particular to a high pitch edge and middle and low pitch edge integrated integral vibrating diaphragm, wherein the high pitch edge and the middle and low pitch edge of the high pitch vibrating diaphragm are in the same structure and work all the time.
Background
At present, the vibrating diaphragm of the electric loudspeaker has two categories of a high-pitch vibrating diaphragm and a middle-low pitch vibrating diaphragm. High-pitch diaphragms are basically mature except for material changes, and medium-pitch diaphragms mainly comprise cones and flat plates. The selection of the material and the change of the style of the middle and low sound diaphragm are also various. However, the drive for "live sound" has driven innovation in "full range electro-dynamic speaker" units, such as coaxial electro-dynamic speakers and stereo wave coaxial electro-dynamic speakers. Most of the coaxial electrodynamic loudspeakers have obvious individuality, namely a high pitch unit loudspeaker is coaxially or asymmetrically arranged at the front end of the inner side of a middle and low sound vibrating diaphragm, namely the same is the same as JBL company in America, and the structure expands the sound range to the high end and the low end so as to realize the 'whole sound range'. However, the vibration of the treble diaphragm and the bass diaphragm still belongs to a bridge and a road, well water does not make contact with river water, and the phenomena that the number of each blowing is changed and the tone of each walking is changed, namely hysteresis distortion of each blowing is superposed and cannot be perfect are caused. The diaphragms with various structures respectively have moving coils with very different masses, particularly the access of a frequency division circuit and the serial connection of a capacitor in a loop of the moving coil of a treble unit, so that the distortion caused by the moving coils is actually artificial distortion! Contrary to the pursuit of "live sound" and "full range". In this regard, the silk diaphragm was developed exclusively by the president of poplars in taiwan, which is said to achieve "full-range" coverage.
In a word, over one hundred years, the integrated integral diaphragm which is pushed by only one moving coil and vibrates coaxially and synchronously with the high-pitch diaphragm and the middle-low-pitch diaphragm does not appear in the electric loudspeaker product.
Disclosure of Invention
The invention provides an integrated high-pitch vibrating diaphragm and medium-low pitch vibrating diaphragm which can be synchronously pushed by only one moving coil, aiming at the defects that in the prior art, double distortion caused by the driving of the high-pitch vibrating diaphragm and the medium-low pitch vibrating diaphragm by respective moving coils and a coaxial loudspeaker are only mechanical coaxial and do not have false coaxial current coaxial, and develops a new way for realizing a full-range electric loudspeaker unit on the vibrating diaphragm.

The middle and low sound vibrating diaphragms on the whole vibrating diaphragm are processed into longitudinal corrugated shapes or longitudinal corrugated shapes, and are shaped at one time, so that the splitting vibration of the middle and low sound vibrating diaphragms is avoided, and the distortion is reduced. In particular light panels with a gradual thickness variation. The overall mass of the whole diaphragm is greatly reduced, the sensitivity is improved, meanwhile, the strength is increased, the bass is full and thick, and the whole diaphragm is not influenced by air humidity. Through high and low temperature aging treatment, the phenomenon that the timbre changes with the temperature is avoided. The high pitch folding edge and the middle and low pitch folding edge are in the same structure and the same work.

Example 1
Once-shaped conical integrated vibrating diaphragm: see schematic diagram 1. The integrated diaphragm is formed by one-time pressurizing by using the whole piece of the same material. The high-pitch diaphragm main body, the high-pitch folding edges, the middle and low-pitch diaphragm main body and the middle and low-pitch folding edges are integrated, and the integral diaphragm with the same structure and the same work is naturally formed. The movable coil is located lower (bottom) portion in such vibrating diaphragm, and direct juncture with high pitch vibrating diaphragm main part, high pitch hem bonds, and high pitch vibrating diaphragm main part is located the middle part, and well bass vibrating diaphragm and well bass hem are located upper portion. The vibration of the moving coil directly reaches the high-pitch vibrating diaphragm main body and is transmitted to the middle-low pitch vibrating diaphragm main body through the high-pitch folding edge, and synchronous vibration-synchronous fax is achieved.
