[Prior art and its problems]

Resonance plates mainly change the sound quality depending on the intensity of the sound depending on the acoustic system. Because of this, the equipment uses good acoustic materials and has sufficient strength design. By applying the I have to make sure that this is a win.

0003 However, the resonant plate of a speaker made using conventional technology has an ordinary and unfavorable sound quality. Using the material, also simply insert one rough acoustic coil from the center into the rough resonator plate above. Because the vertical vibration is not corrected, deformation accidents regularly occur. Easy to use; more recently, a type of so-called honeycomb flat speaker has been introduced in the United States and Japan. There were some products that were damaged, or there were unavoidable flaws that made them easily deformed.

[Means to solve the problem]

In order to solve the above problems, this idea is a kind of acoustic resonator plate body. The ripple-like shape is formed using a press machine, and the direction of the ripples is determined by the shape of one inside. From the center, it is strictly spread horizontally around the four circumferences, and there is a straight line between the peaks and valleys. The main body of the resonator plate has an upper piece and a lower piece, and is connected completely. The rippling part ▲hin▼ in the center of the upper and lower pieces is tightly covered; In addition, another paper tube type magnetic coil is tightly connected to the resonance plate body. This increases the amplification of the sound so that the top and bottom of the resonator plate has the function of vibration, and also The main body of the resonator plate is formed into a triangular prism like reinforced concrete, and its strike direction is also ripple-shaped. , the straight line of the rays maintains maximum stability, so hard and uncorrected variations are avoided. Since it cannot be shaped and is easily manufactured, we also confirmed that it is easy to make a book; A new structure featuring a triangular transverse wave type resonator plate.

【Example】

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0006] If you refer to ▲Figures▼1 and ▲Figure▼2, you will see a kind of triangular structure that shows an example of the configuration of this invention. In the transverse ripple type resonant plate assembly (10), the main body (12) of the resonator plate has an upper It is composed of a piece (13), a lower piece (14), and a paper tube coil (15). In 2), the shape of the ripples (16) is pressed by a press machine, and the shape of the ripples (16) is pressed. In the strike direction, from one center point, it spreads horizontally around the four circumferences in a tight manner. Between the peaks and valleys of ripples (16), there is a straight line of rays that continues and connects. In addition, by establishing appropriate strength and weight, the wave of the material is determined by the strength of the material used. The distance, wave height, and width of wave peaks and wave troughs are appropriately designed, and the top of the resonator plate body (12) is and below are provided with an upper piece (13) and a lower piece (14), which are centered from one center point. Each ripple part ▲Hin▼ (16) was assembled into a circular triangular prism with reinforced concrete. The origin of the vibration is the end of the ripple (16) where it has spread. Because there was one soft circular arc type concave groove (31); A paper tube type coil (15) is tightly connected to the main body (12) at the tip. , because the coil on the surface of the paper tube (15) can act as a magnetic field, the acoustic effect In addition, the resonator plate body (12) is made of a triangular prism made of reinforced concrete, as described above. It has a ripple-shaped dip point (16) in its strike direction, so it maintains considerable stability. , unexpected deformations that are not corrected cannot easily be made.

[Effect of the idea]

With the configuration explained above, this device has a triangular transverse wave type, and mainly uses the transverse wave. The strike direction of the crest is horizontally distributed from one central point to all four circumferences, and then Since the horizontal ripples covered from the bottom piece are highly stable, there is little deformation in this case, and the frequency is extremely low. It has many high efficiency conditions for speakers, and is easy to manufacture. Since there was a simple drawback, we constructed a new structure of the triangular horizontal ripple type resonator plate of the present invention. ing.
