Technical Field

The utility model relates to an audio amplifier technical field especially relates to an audio amplifier box structure.

Background

The loudspeaker box with the plastic shell can finish various shapes, the inside of the loudspeaker box can meet the requirements of various convenient assembly structures, the loudspeaker box is often used in the manufacture of loudspeaker box products, for large-size loudspeaker box products, a large-size shell plastic mold is large, the cost is high, large-size parts are influenced by various factors when injection molding is carried out, the size deviation of the parts is large, the appearance problems such as obvious section difference and the like are easy to occur after the loudspeaker box is assembled, the number of parts is large, the universality is poor, and therefore the loudspeaker box body structure is provided for solving the problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem that the existing loudspeaker box body mould is large, the cost is high, the part size deviation is large, the part universality is poor, and the proposed loudspeaker box body structure is provided.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a loudspeaker box body structure, includes the procapsid and the back casing that pair mutually, all be equipped with the stereo set mounting hole that runs through on procapsid and the back casing, the casing edge one side of procapsid and back casing all is equipped with inserts the bone, the casing edge opposite side of procapsid and back casing all be equipped with insert the recess that the bone matches, the inboard of procapsid and back casing is crisscross to be equipped with fixed screw hole and the fixed screw post that closes mutually.

Preferably, the fixed screw column and the fixed screw hole are provided with a plurality of reinforcing rib plates with the inner wall connecting node of the rear shell/front shell.

Preferably, the stereo set mounting hole is two of symmetry setting, all be equipped with the speaker through the fixed riveted structure in the stereo set mounting hole.

Preferably, the front shell and the rear shell are plastic shells with the same structure, and the front shell and the rear shell are the same parts formed by injection molding in the same mold.

Preferably, an assembly gap is formed between the insertion bone and the groove on the same front shell or the same rear shell.

The utility model provides a pair of loudspeaker box body structure, beneficial effect lies in: the utility model discloses a same procapsid and back casing are made to same mould, have saved the mould expense of audio amplifier design, and then have reduced the part kind, have reduced warehouse work load, simultaneously because procapsid and back casing are same part, the external dimension is unanimous after the assembly, furthest has reduced appearance problems such as section difference, has practicality, is fit for promoting.
