Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic products, in particular to a CD player. Background Art
[0002] CD players are popular among many users because of their convenience in carrying and good acoustic effects. Traditional CD players generally only come with one type of face cover, such as a plastic face cover. However, in addition to plastic face covers, there are also metal face covers and fabric face covers. If the existing CD player is equipped with a plastic face cover, it usually cannot be replaced with a metal face cover or a fabric face cover because the face covers made of different materials cannot be commonly assembled with the face shell of the CD player. If you want to replace the face cover, you need to replace the face shell that can be adapted to the face cover together, resulting in the need to equip different molds for production, which is not only inflexible but also significantly increases the cost. Content of the Utility Model
[0003] Aiming at the defects of the prior art, the utility model provides a CD player with a simple structure, more reasonable design, more convenient use, capable of reducing costs and capable of flexibly replacing the face cover.
[0004] To solve the above technical problems, the utility model adopts the following technical solutions: A CD player capable of flexibly replacing the face cover includes a housing, a PCB board and a speaker. The housing includes a middle shell, a face shell and a face cover. A CD door is installed at the bottom of the middle shell. The face shell and the speaker are installed on the middle shell, and the face cover is installed on the face shell. It is characterized in that: there are three types of face covers, namely a fabric face cover, a metal face cover and a plastic face cover. The fabric face cover is equipped with a face cover bracket, and a number of buckling feet with reverse buckles are arranged on the bottom surface of the face cover bracket; the bottom surface of the plastic face cover has the same structure as the face cover bracket and also includes buckling feet; a number of insertion feet are arranged on the bottom surface of the metal face cover; a number of buckling holes matching the buckling feet and a number of insertion holes matching the insertion feet are arranged on the face shell. The fabric face cover is fixedly combined with the face shell by inserting the buckling feet of its face cover bracket into the buckling holes, the plastic face cover is fixedly combined with the face shell by inserting the buckling feet of its bottom surface into the buckling holes, and the metal face cover is fixedly combined with the face shell by inserting the insertion feet of its bottom surface into the insertion holes.
[0005] Furthermore, a number of fixing holes are also arranged on the face shell, and a number of fixing columns matching the fixing holes are respectively arranged on the bottom surfaces of the plastic face cover and the face cover bracket. When the fabric face cover is assembled with the face shell, a strengthened fixing structure is formed by inserting the fixing columns of the face cover bracket into the fixing holes of the face shell. When the plastic face cover is assembled with the face shell, a strengthened fixing structure is formed by inserting the fixing columns of its bottom surface into the fixing holes of the face shell; after each fixing column is inserted into the fixing hole, it is locked with the face shell and the middle shell by screws.
[0006] Furthermore, a number of the plug pins are provided at the edge position and the central area of the metal face cover respectively, and a number of the plug holes corresponding to the plug pins are provided at the edge position and the central area of the face shell respectively.
[0007] Preferably, the metal face cover is an aluminum alloy face cover, a stainless steel face cover or an iron face cover.
[0008] Furthermore, mesh holes for sound transmission are provided at the positions on the face cover bracket that are aligned with the speakers. The cloth face cover covers the surface of the face cover bracket through adhesives, and the face cover bracket is made of plastic material.
[0009] Furthermore, mesh eyes are provided on the surface of the plastic face cover, and mesh holes for sound transmission are provided at the positions on the plastic face cover that are aligned with the speakers.
[0010] Furthermore, there are at least three snap holes, which are arranged along the edge and the middle area of the face shell, and each fixing hole is arranged along the edge of the face shell.
[0011] In the utility model, a variety of fixing structures adapted to different fixing components are arranged on the face shell, such as snap holes adapted to snap feet, fixing holes adapted to fixing posts, plug holes adapted to plug pins, etc. At the same time, a cloth face cover, a metal face cover and a plastic face cover are arranged. The cloth face cover is assembled to the face shell through the face cover bracket with snap feet and fixing posts. The metal face cover is fixed on the face shell by inserting the plug pins into the plug holes, and the plastic face cover is installed on the face shell by the same fixing method as the face cover bracket. In this way, different types of face covers can be replaced more flexibly, which is not only more convenient to use, but also can reduce the mold cost and lower the cost. Description of the Drawings
