Description
本發明涉及一種喇叭，尤其涉及一種喇叭音膜及其製作方法。The invention relates to a horn, in particular to a horn sound film and a manufacturing method thereof.
習知的一種喇叭音膜包括一圓形的塑膠材質的懸邊部和一紙質的圓形振膜。懸邊部呈中空的環形狀，振膜藉由人工用膠水粘貼於懸邊部的中空處並將懸邊部的中間封閉，振膜的圓心與懸邊部的圓心同心。A conventional horn sound film includes a circular plastic material overhang and a paper circular diaphragm. The hanging portion has a hollow ring shape, and the diaphragm is adhered to the hollow portion of the hanging portion by manual glue and the middle of the hanging portion is closed, and the center of the diaphragm is concentric with the center of the hanging portion.
惟，使用人工用膠水將振膜粘貼於懸邊部上時，容易出現粘貼位置偏移，使振膜和懸邊部的圓心不同心，這樣會增大喇叭的失真程度，影響喇叭的質量。另，習知的使用紙質材料的喇叭音膜之喇叭，通常在高頻的表現上不佳。However, when the diaphragm is attached to the overhang portion by using artificial glue, the offset of the sticking position is likely to occur, and the center of the diaphragm and the hanging portion are not concentric, which increases the distortion of the horn and affects the quality of the horn. In addition, the conventional speaker of a horn sound film using a paper material generally does not perform well at high frequencies.
因此，有必要提供一種在高頻上表現較好的喇叭音膜，以提升喇叭的質量。Therefore, it is necessary to provide a horn sound film that performs well at high frequencies to improve the quality of the horn.
本發明的目的是針對習知技術存在的缺陷和不足提供一種在高頻上表現較好的喇叭音膜及其製作方法，提升喇叭的質量。The object of the present invention is to provide a horn sound film which performs well at high frequencies and a manufacturing method thereof for the defects and deficiencies of the prior art, and to improve the quality of the horn.
為實現上述目的，本發明之喇叭音膜，裝設於一喇叭上，包括一振膜和一懸邊部；振膜由丙烯腈-丁二烯-苯乙烯共聚物塑膠製成，表面電鍍有一層奈米材料；懸邊部由室温硫化硅橡膠模內成型於振膜的外周緣上。To achieve the above object, the horn sound film of the present invention is mounted on a horn, including a diaphragm and a hanging portion; the diaphragm is made of acrylonitrile-butadiene-styrene copolymer plastic, and the surface is plated with A layer of nano material; the overhang portion is molded on the outer periphery of the diaphragm by a room temperature vulcanized silicone rubber.
為實現上述目的，本發明之喇叭音膜的製作方法，包括如下步驟：
步驟1、使用丙烯腈-丁二烯-苯乙烯共聚物塑膠成型出一圓形的振膜；
步驟2、將該圓形振膜表面電鍍上一層奈米材料；
步驟3、將該圓形振膜放置於一模具內，使用室温硫化硅橡膠在該模具內於振膜的外周緣上成型出一圓環狀的懸邊部，懸邊部外表面的內側緣處成型出一圓環形的安裝凹槽，所述振膜的外周緣固定於安裝凹槽內，其圓心與安裝凹槽的圓心同心。
To achieve the above object, the method for fabricating the horn sound film of the present invention comprises the following steps:
Step 1. Using a acrylonitrile-butadiene-styrene copolymer plastic to form a circular diaphragm;
Step 2, plating a surface of the circular diaphragm with a layer of nano material;
Step 3. The circular diaphragm is placed in a mold, and a ring-shaped hanging portion is formed on the outer circumference of the diaphragm in the mold by using room temperature vulcanized silicone rubber, and the inner edge of the outer surface of the hanging portion is formed. A circular mounting groove is formed, and the outer periphery of the diaphragm is fixed in the mounting groove, and the center of the circle is concentric with the center of the mounting groove.
如上所述，本發明喇叭音膜及其製作方法藉由振膜由丙烯腈-丁二烯-苯乙烯共聚物塑膠製成，並在振膜的表面電鍍一層奈米材料，然後使用室温硫化硅橡膠使懸邊部成型於振膜外周緣上，從而能確保振膜與懸邊部同心，避免增大喇叭的失真程度，另，使用本發明喇叭音膜的喇叭之高頻效果比使用紙質材料的喇叭音膜之喇叭更好，藉以提升喇叭的質量。As described above, the horn sound film of the present invention and the manufacturing method thereof are made of acrylonitrile-butadiene-styrene copolymer plastic by a diaphragm, and a layer of nano material is plated on the surface of the diaphragm, and then room temperature silicon sulfide is used. The rubber forms the overhang portion on the outer periphery of the diaphragm, thereby ensuring that the diaphragm is concentric with the hanging portion, and avoids increasing the distortion of the horn. Moreover, the high frequency effect of the horn using the horn sound film of the present invention is higher than that of using the paper material. The speaker of the speaker sound film is better, so as to improve the quality of the speaker.
