Description

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.

preferably, the middle and low sound diaphragm main body, the middle and low sound folding edge, the high sound diaphragm main body and the high sound folding edge are connected through a connector through a high sound fixing ring. The high pitch retainer plate and the connector are used for combining two originally separated high and medium pitch diaphragms into one.
Preferably, the mid-bass diaphragm body is a light plate with a longitudinal corrugation shape, a longitudinal corrugation shape or a thickness gradually changed. 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. The high pitch hem and well bass hem are the isomorphism worker in nature on the integration vibrating diaphragm, and it is littleer than the whole vibrating diaphragm distortion that unites two into one behind the use connector through the high pitch retainer plate.
Preferably, the connection object is an adhesive or a welding object.
Preferably, the integrated diaphragm is driven by a moving coil. The integrated integral diaphragm is pushed by only one moving coil.
Due to the adoption of the technical scheme, the invention has the remarkable technical effects that: the invention only uses a moving coil to push the integrated diaphragm of the high pitch diaphragm, the middle pitch diaphragm, the high pitch edge and the middle pitch edge, which is the real coaxial and synchronous vibrating integral diaphragm, and compared with the magnetic hysteresis distortion of the pseudo coaxial electric loudspeaker formed by mechanically overlapping two units, the pseudo coaxial electric loudspeaker reduces 50 percent, has wide range of sound range and purer timbre.
