Abstract
The invention discloses a low-distortion earphone speaker support which comprises a support body. A circular hole for containing a magnetic circuit system is formed in the center of the support body. A plurality of reinforcing ribs which are connected to the edge of the support body from the hole wall of the circular hole are arranged on the support body. At least one bent portion is arranged on each reinforcing rib. The bent portions are arranged on the reinforcing ribs, and therefore the path for transmitting vibration of the magnetic circuit system to the edge, for fixing a membrane, of the support body is prolonged; attenuation and delay of vibration in the transmission process are increased according to the prolonging of the vibration transmission path, and therefore the amplitude of vibration modulated to the membrane is decreased, and distortion of a speaker is reduced.
Description
Technical field
The present invention relates to a kind of earphone horn support of earphone horn support, particularly a kind of low distortion.
Background technology
In the time of earphone horn work, due to the existence of active force and reaction force, except the vibration of diaphragm, magnetic circuit system also can vibrate.And this vibration meeting is delivered to diaphragm by support fixing and support magnetic circuit system, give diaphragm a modulation vibration.This modulation vibration is contrary and exist the regular hour to postpone with the direction of vibration of diaphragm, can cause distortion.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of earphone horn support of low distortion.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of earphone horn support of low distortion, comprise rack body, described rack body center is provided with for placing the circular hole of magnetic circuit system, described rack body is provided with some reinforcements that are connected to rack body edge by circular hole hole wall, is provided with the bending part that is at least provided with on described reinforcement.
Described bending part is provided with one, and described reinforcement is L font structure.
Described reinforcement disposes six, the reinforcement of six around round hole axial evenly annular be arranged on rack body bottom.
On rack body end face, offer some air-vents.
Described air-vent is arranged between two adjacent reinforcements, and the air-vent both sides of the edge between two reinforcements are hypotenuse structure, and the extended line of this hypotenuse structure is without the center of rack body.
The invention has the beneficial effects as follows: a kind of earphone horn support of low distortion, comprise rack body, described rack body center is provided with for placing the circular hole of magnetic circuit system, described rack body is provided with some reinforcements that are connected to rack body edge by circular hole hole wall, on described reinforcement, be provided with the bending part that is at least provided with, the present invention by arranging bending part on reinforcement, extend magnetic circuit system vibration and be delivered to the fixedly path at the rack body edge of diaphragm, prolongation along with vibration transfer path, decay and the delay of vibration in transmittance process can strengthen, thereby reduce to be modulated to the Oscillation Amplitude on diaphragm, reduce the distortion of loudspeaker.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is rearview of the present invention;
Fig. 2 is the generalized section of A-A in Fig. 1 of the present invention;
Fig. 3 is front view of the present invention.
Embodiment
Referring to figs. 1 through Fig. 3, Fig. 1 to Fig. 3 is the structural representation of a specific embodiment of the present invention, as shown in the figure, a kind of earphone horn support of low distortion, comprise rack body 1, this rack body 1 is a circular support in the present embodiment, described rack body 1 center is provided with for placing the circular hole 2 of magnetic circuit system, described rack body 1 is provided with some reinforcements 3 that are connected to rack body 1 edge by circular hole 2 hole walls, in the present embodiment, described reinforcement 3 disposes six, the reinforcement 3 of six around circular hole 2 axis evenly annular be arranged on rack body 1 bottom.
As shown in the figure, on described reinforcement 3, be provided with the bending part of, make reinforcement 3 be L font structure, by bending part being set on reinforcement 3, extend magnetic circuit system vibration and be delivered to the fixedly path at the rack body edge of diaphragm, along with the prolongation of vibration transfer path, decay and the delay of vibration in transmittance process can strengthen, thereby reduce to be modulated to the Oscillation Amplitude on diaphragm, reduce the distortion of loudspeaker.
Further, as shown in the figure, between two adjacent reinforcements 3, offer some air-vents 4, because reinforcement 3 is L font structure, article two, 4 both sides of the edge of the air-vent between reinforcement 3 are hypotenuse structure, and the extended line of this hypotenuse is all without the center of circle of rack body 1, and edge is along the line stressed without the center of circle, not easy to break.
Above better enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; as the bending part of reinforcement 3 can be set to a plurality of; make reinforcement 3 be Z-shaped, ripple type etc.; the conversion being equal to that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or accordingly change, all should belong in protection scope of the present invention.
