Description

M254035 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to a component used in a la < (or speaker) as a suspension. [Previous technology] According to the general example, the typical moving coil type P8 structure is shown in the first figure, and includes a power system, a drum paper and a suspension system. The power system further includes: magnet A, pole piece B, upper iron C, gap D and voice coil E. The diaphragm F is a cone-shaped drum paper or a hemispherical sound cone for moving air. The suspension system is composed of the elastic wave G and the overhang structure, which is responsible for the directional movement of the traction diaphragm F. Its working principle is that when an electric current flows through the voice coil, an electromagnetic field is generated. This electromagnetic field is at right angles to the magnetic field of the permanent magnet on the remaining σ, which causes the moving coil to be subject to the gap D (the gap between the voice coil and the magnet). Within the movement. The mechanical force generated by this movement causes the diaphragm F attached to the voice coil to move vertically and vertically (vibration), so that the air vibrates to send audio to the human ear, achieving the purpose of sound restoration for people to listen to. Conversion of electrical energy to acoustic energy. The elastic wave is an important component in the La Ba's suspension system. It is used to support the voice coil so that the diaphragm attached to the voice coil can produce the expected vibration. Its effect is similar to the buffer spring included in the car suspension system. Therefore, whether the elastic wave is suitable or not depends on whether it has sufficient elasticity and strength. Please refer to the second figure for the general known elastic wave structure, which includes a plurality of concentric circular peaks G 1 and troughs G 2, so that the radial section has a continuous wave shape (as shown in the third A); the elastic wave The center hole of G is used to combine the voice coil, and the outer periphery of the elastic wave is used to hang from La's case. This traditional elastic wave structure is based on

M254035 IV. Creation Instructions (2) Contains the reason for the crests and troughs of multiple concentric circles, which makes the BB section of the second figure (the section perpendicular to the radius shown in the third figure B when the elastic wave is subjected to force) ) Although it has sufficient strength, the flexural strength in the AA section of the second diagram (the radius section shown in the third A) is not enough; because the force of the elastic wave is not very average (based on mechanical Factors or if it is placed in an uneven position, etc.), after a period of use, it will easily cause deformation of the elastic wave, which will affect its performance as a horn suspension system. It is necessary to improve based on the lack of this traditional bomb structure.

[New content] "Technical Problems to Be Solved" This creation is mainly to solve the traditional elastic wave. The complex crests and troughs are circular and concentrically arranged with weak strength, so that they are prone to deformation after long-term imbalance. Missing. "Technical means to solve the problem" The first technical means of this creation is to set a plurality of turning points at each crest and trough of the elastic wave, so that each crest and trough are formed into a polygon. With this structure, The radial section of the elastic wave has higher flexibility strength.

The second technical means of this creation is to set a number of turning points on the crests and troughs of a part of the bombardment, so that the crests and troughs of these parts are formed into polygons. With this structure, the radius of the bombardment is The cross section has higher flexibility strength. The third technical method of this creation is to use the mold to shape the elastic wave.

Fourth, the creation instructions (3) Peaks and troughs simultaneously form a turning point. The fourth technical means of this creation is that the points are located at the same position, so that the g ^ wave peak and the turning point set by the trough line are aligned in a straight line, so that the elastic wave at the imperial point is directed toward the center from the outer diameter of the elastic wave elasticity. 9 It is still able to maintain a good "at the strength of" For the change in the shape of the phase peaks and troughs of the concentric circular spring waves of Scitech and the traditional to obtain the intensity 'This is mainly the use of the elasticity of wave holding elastic waves, Let the elasticity of the elastic wave increase, while still being able to maintain longer. Better performance and longer service life [Implementation] The following diagrams will make the creation clearer. After the explanation of the step-by-step method, when the fourth picture shows that the body of this creation is shaped by a plurality of concentrically arranged elastic wave sections with continuous radius sections, the crest 11 and trough 1 2— The first embodiment in which the crests 11 and troughs 12 form a polygonal circular crest and trough are separated by a radius to obtain a high degree of deflection. The first embodiment is based on the annular crests 11 and troughs 2 of the elastic wave. Making the wave shape, a plurality of turning points 1 3 are formed in the same formation f of the forming process, so that, by attacking the polygonal structure, the original plural length is shorter, resulting in elastic wave strength. The elastic wave can be made of various cloths or other materials. The manufacturing method is to cut the pre-cut piece into a circular shape, v mold up and down.

Fourth, the creation instructions (4) ~ --------- the die in advance of the peaks and valleys described in the 'between the molds' in advance the peaks and troughs engraved, received in the sheet: ^ polygon wave required for the elastic wave The upper and lower sides of the sheet body are used in a state where 2 G is combined and applied, and the elastic wave structure and shape of the upper and lower molds are used. 1 force 'allows the sheet body to be shaped into a predetermined first implementation shown in the fourth figure, where each side of the polygon is formed as a straight line 1 4 and the formula is such that the peaks 1 1 and the troughs 12 2 1 3. As shown in the fifth figure, the two straight lines 14 of the second ^ $ of this creation are turning points. The sides of the polygon are formed with a small curvature, and the ^ application method makes the peaks and valleys 15 and the connected two arcs 1 Between the & concave arcs in the direction from the center to the point, as a third embodiment, the peaks can invite the points Z1 and 3. The original curve shown in Figure 6 has a large curvature, and the sides of the polygon recessed in the direction of the center point are formed as the fourth embodiment of the creation. The crest fish = 15, Each side of the polygon with an arc 16 / t protruding toward the outer diameter of the elastic wave shown in the seventh figure is formed as a turning point 13. Between the connected two arcs 16 is a circular wave of a play, and a plurality of circular polygons are analogized. All of the above figures are used to stagger the creative spirit in this creative peak and trough. The system can use polygons, wave crests and troughs 17, after the absence of iC, then set Futai 32 troughs, and multiple circular crests and troughs, according to the Moon Dagger to achieve the effect of improving the flexibility strength. The stated ones are only used to explain the better of this creation. This creation makes any form of limitation. ",, any modification or change made to the creation under phase = shall still cover the scope of protection intended.
