Abstract
The utility model discloses a sound box iron net connecting structure.A shell is provided with a mounting groove, the iron net is provided with a net edge, the net edge is fused into the groove bottom of the mounting groove, the groove bottom of the mounting groove is melted through ultrasonic welding, then the net edge is inserted into the melted groove bottom, and the net edge is firmly connected with the groove bottom of the mounting groove after cooling, so that a through hole is not required to be designed, the iron net does not need to be folded, and the net edge is not exposed outside, thereby the whole body is more attractive.
Description
Technical Field
The utility model relates to a sound box, in particular to a sound box iron net connecting structure.
Background
General audio amplifier all is equipped with the iron mesh lid and prevents to damage the loudspeaker on the loudspeaker, is equipped with the hem on the net limit of iron mesh and is used for the card to go into in the through-hole of audio amplifier casing, and net limit and hem pass the through-hole then the hem card is on the casing.
However, at present, due to the requirement of the shell structure, through holes cannot be formed in the part of the sound box shell where the iron net is installed, and therefore a new structure needs to be designed to achieve installation of the iron net.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a sound box iron net connecting structure.
The technical scheme adopted by the utility model for solving the technical problem is as follows:
the utility model provides a sound box iron mesh connection structure, includes casing and iron mesh, its characterized in that: the iron net is provided with a net edge, and the net edge is fused into the groove bottom of the mounting groove.
The bottom surface of the net edge is provided with a plurality of sawteeth.
The mounting groove is an annular groove, and the net edge is an annular shape matched with the annular groove.
The mounting groove comprises two straight grooves and two semicircular grooves, the straight grooves are located between the semicircular grooves and connected with the two semicircular grooves, the net edge comprises two straight edges and two semicircular edges, the straight edges are located between the two semicircular edges and connected with the two semicircular edges.
And sawteeth are arranged on the bottom surface of the straight edge.
The sawtooth is isosceles trapezoid.
The utility model has the beneficial effects that: according to the utility model, the mounting groove is formed in the shell, the net edge is arranged on the iron net and is fused into the groove bottom of the mounting groove, the groove bottom of the mounting groove is melted through ultrasonic welding, then the net edge is inserted into the melted groove bottom, and the net edge is firmly connected with the groove bottom of the mounting groove after cooling, so that a through hole is not required to be designed, the iron net does not need to be folded, and the net edge is not exposed outside, so that the whole body is more attractive.
Drawings
The utility model is further illustrated with reference to the following figures and examples.
FIG. 1 is a view of the overall structure of the present invention;
FIG. 2 is an exploded view of the present invention;
fig. 3 is a partially enlarged structural view of a saw-tooth portion.
Detailed Description
Referring to fig. 1 to 3, the utility model discloses a sound box iron net connecting structure, which comprises a plastic shell 1 and a metal iron net 2, wherein a mounting groove 3 is formed in the shell 1, a net edge 4 is formed on the iron net 2, and the net edge 4 is fused into the bottom of the mounting groove 3.
As shown in the figure, the mounting groove 3 is an annular groove, the net edge 4 is an annular groove matched with the annular groove, and the concrete structure is as follows: the mounting groove 3 includes the straight flute of two relative settings and the double-phase semicircle recess that sets up relatively, the straight flute is located two just with two between the semicircle recess is connected, the net limit 4 includes the straight flange of two relative settings and the double-phase semicircle limit that sets up relatively, the straight flange is located two between the semicircle limit and with two the semicircle limit is connected, and above-mentioned shape matches and has the aesthetic feeling with the structure of loudspeaker. As a further structure of the application, the bottom surface of the net edge 4 is provided with a plurality of sawteeth 5, because the net edge 4 needs to be embedded into the bottom of a molten groove when ultrasonic welding is carried out, in the process, the plastic is melted by the vibration of the iron net and the friction of the plastic, the inserting position of the net edge 4 is closer to the edge of the shell 1 and the wall of the mounting groove 3 is also thin, the excessive melted plastic can cause the bulge deformation of the single thin position, the bulge deformation and the uneven connection of the shell 1 can be easily caused, the appearance and the connection reliability are seriously influenced, therefore, a plurality of sawteeth 5 are arranged on the bottom surface of the net edge 4, the above problems are solved by the design of the saw teeth 5, as a further structure, the saw teeth 5 are arranged on the bottom surface of the straight edge, the vibration contact between the saw teeth 5 and the groove bottom of the mounting groove 3 is small, so that the amount of the melted plastic becomes smaller and spaces for accommodating the plastic are formed among the saw teeth 5, thereby avoiding the plastic from being extruded and bulging. Because the bulge of straight flute position warp obviously, need not carry out sawtooth 5 processing like this at the bottom surface of whole net limit 4, save the cost, the concrete structure of sawtooth 5 lies in: the saw teeth 5 are isosceles trapezoids, so that the processing is easy.
The sound box iron net 2 connection structure provided by the embodiment of the present invention is described in detail above, and the principle and the embodiment of the present invention are explained by applying a specific example herein, and the description of the above embodiment is only used to help understanding the method and the core idea of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
