［産業上の利用分野］
この発明はスピーカ用キャビネット、特に車載用スピー
カキャビネット等の直射日光に晒される状態で使用され
るスピーカキャビネットの改良に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a speaker cabinet, particularly a speaker cabinet used in a state where it is exposed to direct sunlight, such as a vehicle-mounted speaker cabinet.
［従来の技術］
従来スピーカキャビネット、特にポータプル機器や車載
用スピーカ装置のスピーカキャビネットは、合成樹脂の
射出成形品の表面に、着色剤又は顔料とアクリル樹脂を
主成分とした材料を密着性、堅さ、色、色調、耐熱性、
耐湿性等を考慮して適宜選択して塗装していた。[Prior art] Conventional speaker cabinets, especially speaker cabinets for portable devices and car-mounted speaker devices, are made by applying a material mainly composed of colorant or pigment and acrylic resin to the surface of a synthetic resin injection molded product for adhesion and hardness. color, tone, heat resistance,
Appropriately selected coatings were applied in consideration of moisture resistance, etc.

少ない顔料を選定した場合であっても顔料に混合して塗
料材を構成する樹脂の劣化により変色する場合が多かっ
た。[Problems to be Solved by the Invention] However, many speaker cabinets used in outdoor environments, such as car-mounted speakers, deteriorate and fade due to direct sunlight, especially the ultraviolet rays contained therein. This tendency is particularly strong in paints with added dyes, and even if pigments that are less susceptible to ultraviolet rays are selected, discoloration often occurs due to deterioration of the resin that is mixed with the pigment and makes up the paint material.
当該退色又は変色の発生は商品価値を著しく低下させる
原因となる。The occurrence of such fading or discoloration causes a significant decrease in commercial value.
