Abstract
The utility model discloses a sound box, which comprises a decoration net. The decoration net is integrally provided with an inner box body integrally molded by using a mold. The inner box body is provided with a woofer and a circuit board assembly. The two ends of the inner box body are provided with a mid-range tweeter assembly. The mid-range tweeter assembly is composed of a bracket, a phase guiding tube fixed on the bracket, and a mid-range tweeter. The bracket is inserted into the end portion of the inner box body. According to the structure of the utility model, the inner box body is integrally molded by using the mold. In this way, when the inner box body is already molded, the length of the inner box body can be randomly cut. Therefore, by means of only one set of mold, the size requirements on inner box bodies of all types for the sound box can be met, so that the cost is greatly saved. Meanwhile, the inner box body of the sound box is integrally molded instead of the traditional assembly molding mode, thus being better in sealing performance. The acoustics of the sound box is also improved. Moreover, the mid-range tweeter and the phase guiding tube are assembled with the bracket to form the mid-range tweeter assembly in advance, and then the mid-range tweeter assembly is fixedly connected with the inner box body in a plug-in manner. Therefore, the assembly process is greatly simplified and the cost is saved correspondingly.

Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of compact conformation, assembles the audio amplifier simple, cost is low.
The utility model solves the technical scheme that its technical problem adopts:
A kind of audio amplifier, it is characterized in that: comprise decoration website, in decoration website, be provided with by the integrated internal box of mould, bass horn and circuit board assemblies are housed on internal box, internal box two ends are provided with alt horn assembly, this alt horn assembly comprises support, is fixed on phase guide tube and alt loudspeaker on support, and this support is plugged in the end of internal box.
The end of described support is provided with function button.
Described support is provided with bluetooth module.
Described support is provided with link, and the end that described support inserts described internal box by this link forms connection cooperation.
Described link is a cubic stage body, is positioned on an end face of support, and the conflict of the end face of the lateral section of this end face and the end of internal box, thereby realize the installation location of support on internal box.
The contact-making surface of described link and internal box is provided with seal groove.
Described decoration website is provided with ornamental strip, between this ornamental strip and internal box, fixes by the mutual fastening between grab.
The beneficial effects of the utility model are: the utility model discloses a kind of audio amplifier, comprise decoration website, in decoration website, be provided with by the integrated internal box of mould, bass horn and circuit board assemblies are housed on internal box, internal box two ends are provided with alt horn assembly, this alt horn assembly comprises support, be fixed on phase guide tube and alt loudspeaker on support, and this support is plugged in the end of internal box, the internal box of this structure is one-body molded by mould, thereby after its moulding, length can arbitrarily intercept, only need a mold just can realize the dimensional requirement of the internal box of all models of such audio amplifier, thereby save great amount of cost, and one-body molded, compare former assembled formation mode, there is better sealing, the lifting of tonequality is also had to certain help, and alt loudspeaker, phase guide tube and the support of this product are first assembled into alt horn assembly, then by fixing with the mode of internal box socket connection, thereby greatly simplify assembly technology, correspondingly also provided cost savings.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is explosive view of the present utility model;
Fig. 2 is internal structure view of the present utility model;
Fig. 3 is the topology view of internal box;
Fig. 4 is assembled view of the present utility model;
Fig. 5 is the assembled view of alt horn assembly.
Embodiment
With reference to Fig. 1, Fig. 2, the utility model discloses a kind of audio amplifier, comprise decoration website 1, in decoration website 1, be provided with by the integrated internal box 2 of mould, bass horn 3 and circuit board assemblies 4 are housed on internal box 2, internal box 2 two ends are provided with alt horn assembly, and this alt horn assembly comprises support 5, is fixed on phase guide tube 6 and alt loudspeaker 7 on support 5, and this support 5 is plugged in the end of internal box 2.
As shown in the figure, support 5 is provided with link 8, the end that described support 5 inserts described internal box 2 by this link 8 forms to connect and coordinates, and the concrete structure of link 8 is a cubic stage body, be positioned on an end face of support 5 and integrated with support 5, and the end face of the end of the lateral section of this end face and internal box 2 is conflicted, thereby realize the installation location of support 5 on internal box 2, thereby ensure that accurate positioning is convenient in installation process.
