Description
Technical Field
The utility model relates to an audio amplifier field especially relates to an audio amplifier shell.
Background
In recent years, as the size of the sound box is limited due to the smaller and smaller end products, the sound box housing formed by plastic cannot provide sufficient strength in the case of small size, so that the sound box housing partially formed by metal and partially formed by combining plastic is more and more common, and the sound box also has better heat dissipation property due to the metal sheet.
The method is characterized in that the metal sheet needs to be manually placed into the plastic mold, the manual operation is complex, the yield cannot be improved, and the plastic often has injection molding defects such as glue shortage or glue leakage at the metal sheet because the metal sheet needs to be wrapped by a certain amount of plastic and the volume of the sound box is small.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a sound box shell for solve the not enough of prior art.
In order to solve the above problems, the technical solution of the present invention is:
the utility model provides a sound box shell, includes the casing of being made by plastic materials, the casing on be provided with a plurality of casing cavity portions that link up around, casing cavity portion edge is provided with step portion, be provided with the portion of cutting off between the adjacent casing cavity portion, the edge side of casing cavity portion is provided with the casing bump, the casing cavity portion of casing installs the sheetmetal, the area of sheetmetal will be greater than the area of casing cavity portion, the sheetmetal is installed on the portion of cutting off, the sheetmetal edge adopts glue to seal with the casing and bonds.
The utility model has the advantages that: with the sheetmetal through the mode direct mount that bonds on the casing, can the great degree reduce the volume and the plastic thickness of audio amplifier to the equipment is simple during production, and the live time is shorter, and output can obtain great promotion.
Drawings
Fig. 1 is a schematic structural view of a housing of the present invention;
FIG. 2 is a schematic structural view of the present invention;
fig. 3 is a schematic structural diagram of the present invention.
In the figure: 1-shell, 3-metal sheet, 12-shell cavity part, 13-partition part, 14-shell salient point and 15-step part.
Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
Referring to fig. 1-3, the utility model discloses a casing 1 by plastic material makes, casing 1 on be provided with a plurality of casing cavity portions 12 that link up around, casing cavity portion 12 edge is provided with step portion 15, be provided with between the adjacent casing cavity portion 12 and cut off portion 13, the edge side of casing cavity portion 12 is provided with casing bump 14, sheetmetal 3 is installed to casing cavity portion 12 of casing 1, sheetmetal 3's area will be greater than the area of casing cavity portion 12, sheetmetal 3 installs on cutting off portion 13, sheetmetal 3 edge and casing 1 adopt glue sealing bonding.
In practical application, the shell 1 and the lower shell 2 are both made of plastic parts and can be injection-molded by a plastic mold, the shell 1 is provided with a plurality of shell cavity parts 12 which are communicated from front to back, the edges of the shell cavity parts 12 are provided with step parts 15, the metal sheet 3 is installed on the partition parts 13, the partition parts 13 support the metal sheet 3, so that the metal sheet 3 has better strength to prevent the metal sheet from deforming, during installation, glue is directly applied to the periphery of the metal sheet 3 or the shell cavity parts 12 of the shell 1, and then the metal sheet 3 is installed.
The above-mentioned specific implementation is the preferred embodiment of the present invention, can not be right the utility model discloses the limit, any other does not deviate from the technical scheme of the utility model and the change or other equivalent replacement modes of doing all contain within the scope of protection of the utility model.
