Abstract

Provided is a structure of a high-pitched speaker vibration film.
The present invention relates to a structure of a kind of treble loudspeaker vibration film. Mainly, the design of the treble loudspeaker vibration film is improved, and the carbon fiber is distorted into a yarn-like texture-unconstrained structure, such as a paper or nonwoven fabric structure. The carbon fiber content is lowered to 100% or less, and an organic or inorganic material is added and molded. Finish into a thin piece with a thickness of 0.02 to 0.15 mm. Since the vibration film structure made by adding organic or inorganic substances to this carbon fiber is extremely thin, the sound quality due to voice vibration can be heard very cleanly and softly, and the structural hardness is also improved by adding organic or inorganic substances to the carbon fiber, It has characteristics that do not affect the sound quality due to moisture and insect damage.

Description

  The present invention is a kind of treble loudspeaker vibration film structure, mainly the treble loudspeaker vibration film (commonly known as DOM) design, and a thin piece composed of carbon fiber or organic or inorganic material is used for sound vibration. The output sound is beautiful and soft. Further, since the structure has a considerable hardness, it has a feature that there is no fear of affecting sound quality due to moisture or insect damage. In addition, the output sound is cleaner and less noisy than a metal vibration film.

  The structure of the high-frequency loudspeaker vibration film of the publicly known technology was devised early by the contractor, but there are concerns that the structural strength of the high-frequency loudspeaker vibration film of paper material is insufficient and is vulnerable to moisture and insect damage. Does not lead to Later, metal (magnesium, aluminum, titanium, beryllium) high-frequency speaker vibration films were commercialized, but these material structures are extremely strong, eliminating the problems of moisture and insect damage. However, since the voice vibration is large and noisy, further structural improvements are needed. In addition, in the known technology, the same kind of product structure uses a high-frequency speaker vibration film made of finely woven fabric made of nylon yarn, cotton wire or kite yarn. This kind of material has no problem of moisture or insect damage, but has a problem such as turbidity in the sound quality of the sound vibration because the structural strength is insufficient. In addition, it cannot be said that the sound quality of structural products such as plastic and rubber is complete with products of known technology. Therefore, it is necessary to develop a product having a structure.

  The inventor has devised a new high-frequency loudspeaker vibration film structure as a result of repeated research and trial production on improvement of the high-frequency loudspeaker vibration film structure. This structure is manufactured by adding carbon fiber or organic or inorganic fiber, and is molded into a very thin piece. This thin one-piece structure is softer in structure than a metal high-pitched speaker vibration film. However, it is harder than a high-frequency speaker vibration film made of nylon or silk thread. The high-frequency loudspeaker vibration film made of metal, nylon thread, or kite string has excellent sound output, eliminates other defects, and has a structurally moderate hardness. For this reason, the sound quality of the audio output is beautiful and soft. In addition, because it is structurally stronger than just paper, it is resistant to moisture and insect damage. The present invention achieves an inventive step and an improvement over various known high-frequency speaker vibration films.

  As shown in FIG. 1, when the present invention is manufactured, after the fiber is cut, it is dispersed in a distorted yarn shape. The turbulent yarn is produced in a dispersed state, or organic or inorganic fibers in addition to carbon fibers (for example, when the carbon fiber component is 50%, 50% organic or inorganic fibers are added. When adding 20% organic or inorganic fiber), add a thin piece like a paper sheet with a thickness of 0.08-0.2mm, dry the thin piece and impregnate the polymer resin After that, after drying again, through processes such as heating and pressurization, it is finished into objects of various shapes with a thickness of 0.02 to 0.15 mm or thinner, and cut into appropriate sizes to make products Finish.

The invention of claim 1 cuts carbon fiber to form an indeterminately shaped structure dispersed in a turbulent thread shape, and after molding into a thin piece such as a paper sheet, it is thinner, various shapes of high-frequency speaker vibration films The structure of a kind of treble speaker vibration film characterized by realizing the above.
The invention of claim 2 is characterized in that the carbon fiber is made into an unconstrained structure dispersed in the form of turbulent yarns, the carbon fiber content of the high-frequency speaker vibration film to be molded is 100% or less, and organic or inorganic fibers can be added. It is set as the kind of high-pitched speaker vibration film structure of claim | item 1.
The invention of claim 3 is a kind of high-pitched speaker vibration film structure according to claim 1, characterized in that the final thin piece has a thickness of 0.02 to 0.15 mm.

  The present invention is an improvement to the structure of a high-frequency loudspeaker vibration film, in which carbon fiber is disturbed and dispersed in an indefinite direction of the yarn, or the composition of the carbon fiber is reduced to 100% and combined with organic or inorganic fibers. Depending on the composition, it is finished into a very thin piece. This structure has a feature that the metal high-frequency loudspeaker vibration film structure itself is soft, and is harder than the high-frequency loudspeaker vibration film structure made of nylon or silk thread, and has an appropriate hardness. For this reason, a kind of new high-pitched speaker vibration film structure in which the sound quality of sound output is clean and soft is provided.

  FIG. 2 shows an example in which the present invention has a carbon fiber content of 50%. First, after the carbon fiber 1 is cut, it is dispersed in a turbulent thread shape, and an organic fiber 2 (which may be practiced with glass fiber, inorganic fiber, etc.), for example, 50% paper fiber is added, and the thickness is 0.08-0 .Since it is a thin piece such as a 2 mm paper sheet, the thin piece is dried and impregnated with a polymer resin, and then dried again, followed by heating and pressurization, and a thickness of 0.02 to 0.15 mm or thinner. Finished in various shapes such as semi-spherical and wrapper-shaped high-frequency loudspeaker vibration film, cut to the required dimensions, pasted around the speaker ring 3 and fixed, making it light and thin with appropriate hardness A high-quality loudspeaker vibration film with clean and soft sound quality can be realized.

  The main object of the present invention is to improve the structure of the treble speaker vibration film, and the composition in which carbon fiber is disturbed and dispersed in an indefinite direction in the direction of yarn or the composition of carbon fiber is reduced to 100% and combined with organic or inorganic fiber. To finish it into a very thin piece. This structure has a feature that the metal high-frequency loudspeaker vibration film structure itself is soft, and is harder than the high-frequency loudspeaker vibration film structure made of nylon or silk thread, and has an appropriate hardness. For this reason, a kind of new high-pitched speaker vibration film structure in which the sound quality of sound output is clean and soft is provided.
